Abstract: A gas pressure-reducing valve includes a pressure-reducing chamber for generating a gas pressure that acts on one surface of a diaphragm, a valve body that can sit on a valve seat having in its central part a valve hole communicating with the pressure-reducing chamber, and a spring biasing the diaphragm in a direction that detaches the valve body from the valve seat. A valve housing is formed by conjoining a body, a partition, and a cover. The partition forms the pressure-reducing chamber between itself and the body and forms a pressure action chamber between itself and the diaphragm. The cover forms the spring chamber between itself and the other surface of the diaphragm and has the peripheral edge of the diaphragm clamped between itself and the partition. The partition has a through hole for allowing the valve stem to run through in an airtight and axially slidable manner and a communicating hole for providing communication between the pressure action chamber and the pressure-reducing chamber.

Abstract: A clutch of the compressor is selectively engaged and disengaged by a coaction of an engine ECU and an air-conditioning ECU. If an air-conditioning system operating switch is detected as being turned on after a startup of an engine is detected, the clutch is changed from an off-state to an on-state to actuate the compressor to discharge a liquid refrigerant therefrom on the condition that an engine coolant temperature is higher than a reference engine coolant temperature. When the engine coolant temperature is higher than the reference engine coolant temperature, e.g., 40° C., the liquid refrigerant stored in the compressor is discharged of its own accord, and hence the amount of the liquid refrigerant stored in the compressor becomes small.

Abstract: In a clutch in which an end wall of a clutch housing made of an iron and a retainer plate secured to the end wall are connected with a transmitting gear made of an iron and disposed between the end wall and the retainer plate for rotation relative to each other in the predetermined range of angle, damper springs and belleville springs for urging the transmitting gear toward the retainer plate are interposed between the end wall as well as the retainer plate and the transmitting gear, and a thrust washer is mounted to an outer surface of the end wall of the clutch housing for preventing the contact of the end wall and the belleville springs; detent bores are provided in the end wall of the clutch housing, and detent claws are formed on a thin thrust washer to be engaged into the detent bores. Thus, the relative rotation of the clutch housing and the thrust washer relative to each other is prevented, while providing a good assemblability of the clutch.

Abstract: A belt for a continuously variable transmission is provided, which is comprised of metal ring assemblies each having a plurality of endless metal rings laminated one on another, and a plurality of metal elements each having ring slots into which the metal ring assemblies are fitted, and the belt is wound around a drive pulley and a driven pulley to transmit a driving force between the pulleys. When the belt leaves the driven pulley, the metal element falls forward in the direction of advancement with respect to the metal ring assembly. For this reason, a rear end of a saddle surface of the ring slot in the direction of advancement is brought into strong abutment against an inner circumferential surface of the metal ring assembly to produce a concentrated stress, thereby shortening the life of the metal ring assembly. In order to prevent this, the radius of curvature of the rear end of the saddle surface in the direction of advancement is larger than that of its front end to reduce the concentrated stress.

Abstract: A bias current IB additionally provided to a current-controlled circuit 13 in a PLL circuit is the sum of bias currents IB1 and IB2 which are generated by a bias adjustment circuit (18, 19, 20, 21 and 22) and a bias current generating circuit (23 and 24), respectively. The bias adjustment circuit adjusts the bias current IB1 in response to an adjustment start signal ADJ such that a control voltage VC converges to a reference voltage VREF, and ceases the adjustment when the convergence has been achieved. The reference voltage VREF is determined to be a value at an almost middle point in a range of the variable VC in the PLL circuit. The bias current generating circuit has a circuit 23 generating a bias voltage VT and a circuit 24 converting the VT into a current IB2, wherein the temperature characteristic of the bias voltage VT is reverse to that of the control voltage VC under the condition that the frequency of an oscillation signal OCLK is fixed.

Abstract: In a cylinder head 1 of an internal combustion engine, communicating passageways 17, 18, 17′, 18′ for coolant are provided between combustion chambers 3 and pass-through holes 21 to 28 at positions which overlap straight lines L1, L2 connecting centers C2, C3 of the exhaust port openings 6a, 7a with centers C5 to C8 of the pass-through holes 25 to 28 and straight lines L3, L4 connecting centers C9, C10 of the intake port openings 4a, 5a with centers C11 to c14 of the pass-through holes 21 to 24 when a mating surface 2 of the cylinder head 1 with the cylinder block is viewed from the bottom. When peripheries of the exhaust port openings 6a, 7a and intake port openings 4a, 5a thermally expand, the suppression of thermal expansion by the bolts at fastening portions is alleviated by the communicating passageways 17, 18, 17′, 18′.

Abstract: In a non-contact IC card, a driving portion 5 sequentially switches a resonance frequency of a resonance circuit 1. A reference voltage generating portion 6 receives an output voltage of resonance circuit 1 for outputting a prescribed reference voltage. An output value measuring portion 7 measures a magnitude of the output voltage of resonance circuit 1 at each resonance frequency using the reference voltage as a reference. An output value storing portion 8 stores a measurement value (an output value). A manner determining portion 9 selects the largest one of the output values stored in output value storing portion 8, and determines a switching manner corresponding thereto as a suitable switching manner. Thus, the suitable switching manner allowing the most efficient power supply can be achieved.
