Abstract: An actuator unit that drives a switching mechanism for a shift range of an automatic transmission is provided. The actuator unit includes a motor that generates a drive force for driving the switching mechanism, a control substrate that controls the motor, a connector that connects a wire to the control substrate, a housing that includes an opening, a cover that covers the opening, and a shock absorption material that includes a first shock absorption material and a second shock absorption material. The motor and the control substrate are positioned in a housing space defined by the housing and the cover. The control substrate is fixed to the housing. The first shock absorption material and the second shock absorption material are positioned between the control substrate and the cover, and contacts both the control substrate and the cover.

Abstract: An actuator is applied to a shift by wire automatic transmission that operates in response to an electric signal output in accordance with an operation state of an operation member and that performs switching to a selected shift range, and rotates a control shaft provided in the automatic transmission about an axis line. The actuator includes: a case including an insertion hole through which the control shaft is inserted; a motor generating a driving force; gears contained in the case and transmitting the driving force to the control shaft; and an output shaft disposed coaxially with the insertion hole between the gears and the control shaft in the case, the output shaft allowing the control shaft to be inserted through the output shaft such that the control shaft is movable in a direction of the axis line and is rotatable about the axis line integrally with the output shaft.

Abstract: It is an object of the invention to provide a fuel cell system which can reduce vibrations and noises generated upon driving of devices which are the cause of vibration. More specifically, the base portion 100 fixed to the installation surface, support members 111 and 113 on which the devices generating vibration are attached, provided on the base portion and the vibration proofing members 112A and 112B provided between the support members and the base member are provided.

Abstract: [Problem] The object is to provide a fuel cell system capable of ventilating the interior of a casing in a simplified construction and also capable of suppressing the drawing of combustion gas into the interior of the casing even if such gas remains around the casing at the worst.

Abstract: A fuel cell system that can be maintained easily includes a base section fixed on an installation surface, support members installed on the base section, a partition wall attached on the base section and partitioning the space over the base section, and an outer panel detachably secured to the partition wall and the base section.

Abstract: A fuel-cell system is advantageous in preventing exhaust gases to be discharged from an exhaust port from flowing back into an exhaust gas passage without being discharged from the exhaust port. This fuel cell system includes a fuel cell having an anode and a cathode, and an exhaust gas passage having an exhaust port for discharging exhaust gases generated during operation of the fuel cell to the outside. The exhaust gas passage has a backflow suppressing unit at an end portion of the exhaust gas passage on the side of the exhaust port.

Abstract: A temperature sensor is located close to each of a plurality of switching elements. Each of the elements opens and closes a current supplying line from a power supply to a three phase SR motor. A generating circuit of a instruction value for the driving current of the motor generates a target value (It) of the driving current so as to achieve a requested power of the motor and an allowable value of the driving current on the basis of the highest temperature sensed by the temperature sensors. The circuit outputs the target value as an instruction value of the driving current when the target value is smaller than the allowable value and outputs the allowable value as an instruction value of the driving current when the target value is greater than the allowable value.

Abstract: A heat exchanger includes a plurality of tube elements, and a plurality of fins which are alternately stacked together with the tube elements. A tank element is disposed on both sides of the tube elements. At least one of the tank elements is formed of brazing materials and comprises a pair of plates which are U-shaped in cross-section and form an inner space. A partition plate is positioned in the inner space and divides the inner space into a first space adjacent the tube elements and a second space separated from the tube elements by the first space. The partition plate is also provided with a penetrating hole. Each of the tube elements contain at least first and second coolant flow passages. The first coolant flow passages extend through the penetrating holes and into the second space, and the second coolant flow passages extend into the first passage.

Abstract: An evaporator is constructed so as to increaase the efficiency of the heat exchange operation and to decrease the degree of turbulence usually experienced as the coolant flows through the evaporator. A series of tube elements which are alternatingly arranged are provided as the body of the evaporator. Alternatingly arranged inlet and outlet ports at the top and bottom of the tube elements permit the flow of fluid therethrough as it is passed from the inlet conduit through the outlet conduit. An end plate arrangement securely positions the inlet and outlet conduits to the end plate which is connected with the first of the series of tube elements. Due to the connection arrangement between the inlet and outlet conduits and their fixed connection to the end plate, the coolant can flow into and out of the evaporator with an absence of turbulence.
