摘要:
A variable displacement compressor includes a rotor, which is fixed to a drive shaft, and a pivotal swash plate, which is supported on the drive shaft and slides in an axial direction along the drive shaft. A hinge mechanism is located between the rotor and the swash plate. The hinge mechanism rotates the swash plate integrally with the rotor and guides the pivoting and the sliding motion of the swash plate. The hinge mechanism includes a swing arm, which extends from the swash plate. The swash plate is made of aluminum or aluminum alloy material. The swing arm is separate from the swash plate and is made of iron-based metal material. Therefore, while the swash plate is light, the hinge mechanism is strong.

A swash plate type variable displacement compressor comprises cylinder bores, pistons, a suction chamber and a discharge chamber. A suction valve introduces a low pressure gas into a working chamber in each cylinder bore. A discharge valve introduces a high pressure gas in the working chamber into the discharge chamber during a compression stroke. A crank chamber communicates to each of the cylinder bores at rear sides of the pistons. A swash plate is tiltably supported on a drive shaft and connected to each of the pistons through associated rods. The swash plate makes the pistons reciprocate in response to its undulating swing motion and varies its inclination angle based upon pressure differential between pressure in the suction chamber and pressure in the crank chamber therefore adjusting discharge displacement. A gas supply passage communicates each cylinder bore to the crank chamber in order to supply gas having a lower pressure than that in the working chamber at the time of completing the compression stroke. A gas bleed passage communicates the crank chamber to the suction chamber in order to introduce gas in the crank chamber into the suction chamber. A pressure control valve is provided in the gas supply passage or the gas bleed passage to control pressure of gas in the crank chamber. A valve is provided for opening and closing the gas supply passage in the middle of the compression stroke of each of the pistons.

A pneumatic tire 1 which includes a plurality of rib-shaped land portions extending in a tire-circumferential-direction and in which a circumferential groove is formed extending in the tire-circumferential-direction between the land portions. The circumferential groove is provided with an intra-groove groove formed to recess inwardly in a tire-radial-direction from the circumferential groove while having its upper ends at a groove bottom of the circumferential groove. Paired inner wall surface and outer wall surface forming the intra-groove groove each continuously extend in tire-circumferential-direction while meandering in tread-width-direction. The intra-groove groove includes a wide groove portion in which a groove width of the intra-groove groove in tread-width-direction is a predetermined width; and a narrow groove portion which is continuous with the wide groove portion and which has a narrower width than the predetermined width. The wide groove portion and the narrow groove portion are alternately provided in tire-circumferential-direction.

A waterproof case for housing an electronic component includes a case member that has a plurality of breathing holes, and a breathable waterproof filter fitted to the case member at a position corresponding to the breathing holes to cover the breathing holes. For example, open surfaces of at least two of the breathing holes, opened outside of the case member, can be made to face in different directions. Furthermore, the breathing hole has an open area on a side of the breathable waterproof filter, which is larger than an open area of the breathing hole on a side opposite to the breathable waterproof filter, in the case member. Accordingly, the waterproof case enhances waterproofness while circulating air between the inside and the outside of the waterproof case.

A computer system having a hibernation-type resume function which is performed by using an HDD. Provided on the hard disk of the HDD are storage area for storing ordinary data. Also provided on the hard disk is a resume storage area which is large enough to save resume data required to perform a resume operation. The resume storage area is controlled by a BIOS provided for performing the resume operation, not by the operating system (OS) of the computer system. The BIOS accesses the resume storage area when the power supply to the system is switched off, thereby saving the resume data in a resume data memory.

There is provided a webbing take-up device in which a load required to rotate a spool in a webbing drawing direction with reference to a shaft is stabilized in the process of rotating the spool, a stable load can be achieved with small deformation, and miniaturization can be achieved. In an ordinary state, an EA plate keeps its original shape, and the shaft and spool are rotated together with each other. When the shaft is prevented from being rotated in the webbing drawing direction in vehicle sudden deceleration, the EA plate is plastically deformed by a webbing drawing force, and the EA plate is pushed in an internal-angle portion of the spool with rotation of the spool in the webbing drawing direction with reference to the shaft. The EA plate is bent by a U-shaped portion and then wound around the outer periphery of the shaft. The other end portion of the EA plate is pushed into the internal-angle portion at a winding start end portion of the EA plate around the shaft to prevent the subsequential rotation of the spool in the webbing drawing direction with reference to the shaft. Thus, when the webbing is prevented from being drawn, the webbing is drawn by a predetermined length, and energy absorption can be achieved.

A raveling-preventing agent for a glass fiber woven fabric, which contains as essential components a reaction product from an epoxy resin having an epoxy equivalent of 150 to 1,000 and a molecular weight of 500 to 2,000 and a hydroxyl group-containing amine compound, and an isocyanate curing agent. The raveling-preventing agent firmly binds glass fibers together and prevents the raveling of edge-forming warp yarns when applied to sectioned marginal portions of a glass fiber woven fabric. Further it is free from swelling in a solvent used in a thermosetting resin varnish.
