English to Japanese: US20240285397A1: Connecting skirt for attaching a leaflet to a frame of a prosthetic heart valve General field: Law/Patents Detailed field: Medical: Instruments
Source text - English [0049]
The prosthetic valve 150 can have three main components: a stent or frame, 152, a valvular structure 154, and a sealing member 156. FIG. 1B is a perspective view of the prosthetic valve 150 with the components on the outside of the frame 152 (including the sealing member 156) shown in transparent lines for purposes of illustration. The prosthetic valve 150 can have an inflow end 166 and an outflow end 168.
[0050]
The valvular structure 154 can comprise three leaflets 160, collectively forming a leaflet structure, which can be arranged to collapse in a tricuspid arrangement, although in other examples there can be greater or fewer number of leaflets (e.g., one or more leaflets 160). In some examples, the leaflets 160 can be formed of pericardial tissue (e.g., bovine pericardial tissue), biocompatible synthetic materials, or various other suitable natural or synthetic materials as known in the art and described in U.S. Pat. No. 6,730,118, which is incorporated by reference herein.
[0051]
Each leaflet 160 can be coupled to the frame 152 along its inflow edge 162 (the lower edge in the figures; also referred to as "cusp edges") and at commissures 164 of the valvular structure 154 where adjacent portions (e.g., commissure tabs) of two leaflets are connected to each other. In some examples, the commissures 164 can comprise an attachment member (e.g., comprising fabric, flexible polymer, or the like) arranged across a cell (e.g., commissure cell) of the frame 152, the cell formed by struts of the frame. The attachment member can be secured to the struts of the frame forming the cell and the adjacent portions of the two leaflets can be connected to the attachment member to form the commissure 164 (e.g., as shown in FIGS. 2, and 23-25, as described further below).

人工弁１５０は、３つの主要な構成要素、すなわち、ステント又はフレーム１５２、弁膜構造１５４、及びシール部材１５６を有することができる。図１Ｂは、フレーム１５２の外側にある構成要素（シール部材１５６を含む）を説明のために透明な線で示した人工弁１５０の斜視図である。人工弁１５０は、流入端部１６６及び流出端部１６８を有することができる。
【００５０】
弁膜構造１５４は、３つの弁葉１６０を備えることができ、これらの弁葉１６０は、集合的に弁葉構造体を形成し、三尖配置で折り畳まれるように配置することができるが、他の例において、弁葉の数がより多くなる場合又はより少なくなる場合がある（例えば、１つ以上の弁葉１６０）。いくつかの例において、弁葉１６０は、心膜組織（例えば、ウシ心膜組織）、生体適合性合成材料、又は当技術分野で既知であり、参照によって本明細書に組み込まれる米国特許第６，７３０，１１８号に記載の様々な他の適切な天然材料若しくは合成材料から形成することができる。
【００５１】
各弁葉１６０は、その流入縁部１６２（図面における下縁部であり、「弁尖縁部」とも称される）に沿って、かつ、２つの弁葉の隣接する部分（例えば、交連タブ）が互いに接続される弁膜構造１５４の交連１６４において、フレーム１５２に結合することができる。いくつかの例において、交連１６４は、フレーム１５２のセル（例えば、交連セル）にわたって配置された取付け部材（例えば、布地、可撓性ポリマー、又は等を含む）を備えることができ、このセルは、フレームのストラットによって形成される。取付け部材は、セルを形成するフレームのストラットに固定することができ、２つの弁葉の隣接する部分は、（例えば、図２、及び図２３～図２５に示すように、以下に更に説明するように）取付け部材に接続して交連１６４を形成することができる。
English to Japanese: US20220125483A1: Coupling device for coupling a rod to a bone anchor General field: Law/Patents Detailed field: Mechanics / Mech Engineering
Source text - English [0087]
The actuating member 55 is configured as a cam member or eccentric. More specifically, the outer surface of the actuating member 55 forms a cam surface. The actuating member 55 has a central axis C2 and an outer circumferential surface that is eccentric with respect to the central axis C2. When the actuating member 55 is rotated around the central axis C2, the cam surface of the actuating member 55 engages the engagement surface of the pressure member 5 and drives the pressure member 5 axially in the direction of the second end 3b of the receiving part 3. As a result, the clamping force on the head 7 of the bone anchor 1 is increased, and the angular position of the bone anchor 1 relative to the receiving part 3 is locked.
[0090]
When the actuating member 55 is rotated from the non-locking position shown in FIG. 9a to the locking position shown in FIG. 9b, the cam surface of the actuating member 55 acts on the engagement surface 5e of the pressure member 5. The engagement surface 5e is moved in the direction of the second end 3b of the receiving part 3. As a result, the inner surface of the lower portion 5c of the pressure member 5 is pressed against the head 7 of the bone anchor 1, and the angular position of the bone anchor 1 relative to the receiving part 3 is locked. The locking can be reversed by rotating the actuating member 55 back to the non-locking position, so that the pressure member 5 is no longer urged toward the second end 3b by the cam surface.

作動部材５５は、カム部材又は偏心部として構成される。より具体的には、作動部材５５の外面がカム表面を形成する。作動部材５５は、中心軸Ｃ２と、中心軸Ｃ２に対して偏心する外周面とを有する。作動部材５５が中心軸Ｃ２の周りで回転されると、作動部材５５のカム表面が圧力部材５の係合表面に係合し、圧力部材５を受容部３の第２の端部３ｂの方向に軸方向に駆動する。その結果、骨アンカー１の頭部７に対するクランプ力が増大し、受容部３に対する骨アンカー１の角度位置がロックされる。
【００９０】
作動部材５５は、受容部３の通路３ｃ内に受容される。作動部材５５は、通路３ｃ内において中心軸Ｃ２の周りに回転させることができる。図示の実施形態において、作動部材５５は、通路３ｃの内壁に形成された雌ねじ５７と、作動部材５５の外面に形成された雄ねじ５８とによって通路３ｃ内に保持される。雌ねじ５７は、雄ねじ５８と係合し、作動部材５５が回転されると、作動部材５５は、同時に中心軸Ｃ２に沿って軸方向に移動する。
【００９７】
作動部材５５が図９ａに示す非ロック位置から図９ｂに示すロック位置へと回転されると、作動部材５５のカム表面が圧力部材５の係合表面５ｅに作用する。係合表面５ｅは、受容部３の第２の端部３ｂの方向に移動される。その結果、圧力部材５の下側部分５ｃの内面が骨アンカー１の頭部７に押し付けられ、受容部３に対して骨アンカー１の角度位置がロックされる。作動部材５５を非ロック位置に戻すように回転させることによってロック状態を反転することができ、これにより、圧力部材５は、カム表面によって第２の端部３ｂに向かって付勢されなくなる。
English to Japanese: US20260128665A1: Power converters and methods for protecting power converters General field: Law/Patents Detailed field: Electronics / Elect Eng
Source text - English [0034]
FIG. 1 is a diagram illustrating an exemplary power converter 100, in accordance with some embodiments of the present disclosure. As shown in FIG. 1, the power converter 100 may include a protection circuit 110, a charge pump power conversion circuit 120, a controller 130 and one or more detecting circuits 140. In some embodiments, the power converter 100 includes a clock (not shown) to generate one or more timing signals. The controller 130 may implement a deadtime interval based, at least in part on the one or more timing signals generated by the clock. The protection circuit 110 may be electrically coupled to the charge pump power conversion circuit 120. In some embodiments, the protection circuit 110 may include a switching device 112 between a first terminal 102 (e.g., an input terminal configured to receive an input voltage Vin) and the power conversion circuit 120 (e.g., at a node N1).
[0035]
In the embodiments shown in FIG. 1, the charge pump power conversion circuit 120 may be a Dickson charge pump using a switching network having switches SW0-SW4, and SWA-SWD to control the connection of the supply voltage across the load through capacitors C1-C4. Particularly, the charge pump power conversion circuit 120 may be configured to step-down or step-up the input voltage Vin received from the first terminal 102 via the switching device 112 in an ON condition, by storing a portion or multiples of the input voltage Vin across capacitors C1-C4. Each capacitor C1-C4 may help create an intermediate voltage during part of the operating cycle. As the magnitude of the transformation increases, the number of capacitors used in the charge pump increases.
[0036]
The switches SW0-SW4, SWA-SWD may be used to re-arrange the capacitors C1-C4 into different configurations. In some embodiments, the switches SW0-SW4, and SWA-SWD are configured to switch between two different configurations. Accordingly, capacitors C1-C4 can form a first capacitor network in response to the first configuration of the switches SW0-SW4, and SWA-SWD, and can form a second capacitor network in response to the second configuration of the switches SW0-SW4, and SWA-SWD. In some embodiments, the controller 130 controls and sequences transitions of the switches SW0-SW4, and SWA-SWD based on a timing signal received by the controller 130 in such a way as to incorporate any necessary deadtime or clock phase needed. For example, the controller 130 may implement a deadtime interval during the transition, to prevent all switches SW0-SW4, and SWA-SWD from conducting simultaneously when switching between the first configuration and the second configuration.

図１は、本開示のいくつかの実施形態による一例示的な電力変換器１００を示す図である。図１に示すように、電力変換器１００は、保護回路１１０、チャージポンプ電力変換回路１２０、制御器１３０及び１つ以上の検出回路１４０を含むことができる。いくつかの実施形態において、電力変換器１００は、１つ以上のタイミング信号を生成するクロック（図示せず）を含む。制御器１３０は、クロックによって生成された１つ以上のタイミング信号に少なくとも部分的に基づいて、デッドタイム区間を実施することができる。保護回路１１０は、チャージポンプ電力変換回路１２０に電気的に結合することができる。いくつかの実施形態において、保護回路１１０は、第１の端子１０２（例えば、入力電圧Ｖｉｎを受け取るように構成された入力端子）と電力変換回路１２０（例えば、ノードＮ１において）との間にスイッチングデバイス１１２を含むことができる。
【００３５】
図１に示す実施形態において、チャージポンプ電力変換回路１２０は、コンデンサＣ１～Ｃ４を通じて負荷にわたる供給電圧の接続を制御するためにスイッチＳＷ０～ＳＷ４及びＳＷＡ～ＳＷＤを有するスイッチングネットワークを使用するディクソンチャージポンプとすることができる。特に、チャージポンプ電力変換回路１２０は、コンデンサＣ１～Ｃ４全体にわたって入力電圧Ｖｉｎの一部又は倍数を蓄積することによって、オン状態にあるスイッチングデバイス１１２を介して第１の端子１０２から受け取った入力電圧Ｖｉｎを降圧又は昇圧するように構成することができる。各コンデンサＣ１～Ｃ４は、動作サイクルの一部の間に中間電圧を生成するのに役立つことができる。変圧の大きさが増大するにつれて、チャージポンプで使用されるコンデンサの数が増大する。
【００３６】
スイッチＳＷ０～ＳＷ４、ＳＷＡ～ＳＷＤは、コンデンサＣ１～Ｃ４を異なる構成に再配置するために使用することができる。いくつかの実施形態において、スイッチＳＷ０～ＳＷ４及びＳＷＡ～ＳＷＤは、２つの異なる構成間を切り替えるように構成される。したがって、コンデンサＣ１～Ｃ４は、スイッチＳＷ０～ＳＷ４及びＳＷＡ～ＳＷＤの第１の構成に応答して第１のコンデンサネットワークを形成することができ、スイッチＳＷ０～ＳＷ４及びＳＷＡ～ＳＷＤの第２の構成に応答して第２のコンデンサネットワークを形成することができる。いくつかの実施形態において、制御器１３０は、必要なデッドタイム又はクロック位相を組み込むような形で、制御器１３０が受信したタイミング信号に基づいて、スイッチＳＷ０～ＳＷ４及びＳＷＡ～ＳＷＤの遷移の制御及びシーケンス管理を行う。例えば、制御器１３０は、第１の構成と第２の構成との間を切り替える際に全てのスイッチＳＷ０～ＳＷ４及びＳＷＡ～ＳＷＤが同時に導通することを防止するために、遷移中にデッドタイム区間を実施することができる。
