A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. Preferably, the tissue structures will be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment.

In a combined steam and gas turbine engine cycle, a combustion chamber is made durable against high pressure and enlarged in length to increase the operation pressure ratio, without exceeding the heat durability temperature of the system while increasing the fuel combustion gas mass flow four times as much as the conventional turbine system and simultaneously for greatly raising the thermal efficiency of the system and specific power of the combined steam and gas turbine engine.Water pipes and steam pipes are arranged inside the combustion chamber so that the combustion chamber can function as a heat exchanger and thereby convert most of the combustion thermal energy into super-critical steam energy for driving a steam turbine and subsequently raising the operation pressure ratio and the thermal efficiencies of the steam turbine cycle and gas turbine cycle. The combustion gas mass flow can be also increased by four times as much as the conventional turbine system (up to the theoretical air to fuel ratio) and the thermal efficiency and the specific power of the gas turbine cycle are considerably increased.Further, the thermal efficiency of the combined system is improved by installing a magnetic friction power transmission system to transmit the power of the system to outer loads.

A silicon-on-insulator (SOI) RF switch adapted for improved power handling capability using a reduced number of transistors is described. In one embodiment, an RF switch includes pairs of switching and shunting stacked transistor groupings to selectively couple RF signals between a plurality of input / output nodes and a common RF node. The switching and shunting stacked transistor groupings comprise one or more MOSFET transistors connected together in a “stacked” or serial configuration. In one embodiment, the transistor groupings are “symmetrically” stacked in the RF switch (i.e., the transistor groupings all comprise an identical number of transistors). In another embodiment, the transistor groupings are “asymmetrically” stacked in the RF switch (i.e., at least one transistor grouping comprises a number of transistors that is unequal to the number of transistors comprising at least one other transistor grouping). The stacked configuration of the transistor groupings enable the RF switch to withstand RF signals of varying and increased power levels. The asymmetrically stacked transistor grouping RF switch facilitates area-efficient implementation of the RF switch in an integrated circuit. Maximum input and output signal power levels can be withstood using a reduced number of stacked transistors.

Light emitted in side surface directions from side-emitting red, green, and blue LEDs which are arranged on an LED array substrate is introduced into a light guide from side surfaces of a groove-shaped recessed portion, and propagates in the light guide. Thus, the three colors are mixed. The light further propagates in the light guide while being reflected at both side end surfaces of the light guide by the function of a reflective sheet and the like. Thus, color mixing progresses. Further, the light is reflected upward by diffuse reflective means provided on the lower surface of the light guide, and emitted as backlight light to the outside through a diffuse sheet.

A supporting structure is wafer-bonded to the upper face side of a partially or fully processed device wafer. The device wafer includes a transistor having a well region that extends into the substrate material of the device wafer. The source and drain regions of the transistor extend into the well region. After attachment of the supporting structure, the device wafer is thinned from the back side until the bottom of the well region is reached. To reduce source and drain junction capacitances, etching can continue until the source and drain regions are reached. In one embodiment, all of the well-to-substrate junction is removed in a subsequent etching step, thereby reducing or eliminating the well-to-substrate junction capacitance of the resulting transistor. Resistance between the well electrode and the transistor channel is reduced because the well contact is disposed on the back side of the device wafer directly under the gate of the transistor.
