摘要： A vapor delivery needle is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the vapor delivery needle can be advanced a predetermined distance into the prostate with a solenoid actuation mechanism. Methods associated with use of the energy delivery probe are also covered.

摘要： The present invention controls the pressure and flow rate of fluid, in order to obtain uniform performance, configure a closed loop magnetic circuit so as to include an electromagnet, a flapper, and a yoke material, and elastically deform the flapper itself by Maxwell attractive force generated between a magnetic pole of the electromagnet and the flapper to make the separation distance between the nozzle and the flapper variable. As opposed to a rigid flapper structure that swingably moves around a supporting point, like a conventional servo valve, the electromagnet, the magnetic pole, the nozzle, the flapper, and the like are arranged such that a change in magnetic gap directly leads to a change in air gap.

摘要： Electromagnetic actuators capable of generating a symmetrical bidirectional force are disclosed. The electromagnetic actuators include a housing made of a ferromagnetic material and a shaft made of a magnetically inert material movable along an axis within the housing. In one type of actuator, captive permanent magnets are arranged on opposite interior end walls of the housing and an electromagnetic coil is mounted on a central portion of the shaft. The electromagnetic coil is capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on the direction of current through the electromagnetic coil. In another type of actuator, captive electromagnetic coils are arranged on opposing inner end walls of the housing, and a permanent magnet is mounted on a central portion of the shaft. The electromagnetic coils are capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on a direction of current through the electromagnetic coils.

摘要： A haptic solenoid comprises a base member, a fixed pole which is fixed in place on the base member and which has a coil. A mobile pole is arranged facing the fixed pole with a gap therebetween and which moves by way of being attracted to the fixed pole when power is supplied to the coil. Elastic members which are made from a metallic material and which bias the mobile pole in a direction that distances the mobile pole from the fixed pole when power is not supplied to the coil and guide mechanisms, which guide the movement of the mobile pole. The guide mechanisms are configured so as to guide the movement of the mobile pole so that the mobile pole can only move in a direction facing the fixed pole.

摘要： An electromagnetic switch for a starter. The electromagnetic switch includes a cylindrical slidable member that is separate from a plunger, loosely encompasses an outer circumferential periphery of a plunger rod, and is axially movable integrally with the plunger. Whether the solenoid is in its active or inactive state, the slidable member is at least partially axially inserted into an inner circumferential periphery of a cylindrical bore and an outer circumferential periphery of the slidable member is entirely circumferentially in sliding contact with the inner circumferential periphery of the cylindrical bore.

摘要： The invention relates to a hydraulic transmission valve with a magnetizable housing which is integrally configured in one piece with a pole core cone. The transmission valve according to the invention facilitates comfortably coupling in particular startup clutches, shifting clutches or synchronization clutches in a friction locking manner. Still using a transmission valve of this type is facilitated for fewer to no transmission oil changes. Furthermore a transmission valve of this type can also be used in countries with inferior transmission oil quality. The housing includes a connection. The connection defines an anchor stroke and a concentric arrangement between the pole core cone and a pole tube. Thus, the pole tube is fixated the magnetizable pole flange. An anchor that is exclusively supported in the pole tube is magnetically separated from the pole tube through a separation layer with a thickness of 0.01 mm to 0.06 mm.
