A compressor has a compression chamber and a discharge region. The discharge region receives the compressed gas discharged from the compression chamber. A relief valve is mounted to inside of the wall in the discharge region. The relief valve connects the discharge region with the exterior of the compressor so as to discharge the excessively raised pressure in the discharge region.

A liquid crystal apparatus is constituted by a display device for data display, a drive circuit unit for driving the display device, a unit substrate for supplying electric signals to the drive circuit unit, and a tape-form film carrier comprising an insulating substrate and a conductor covered with the insulating substrate for connecting the display device, the drive circuit unit and the unit substrate. A part of the film carrier is provided with a blank portion where the insulating substrate is locally removed to absorb a stress applied to the film carrier. A unit substrate constituting the drive circuit unit is screwed to a supporting member so as to allow a movement thereof relative to the supporting member by use of a space regulating means surrounding the screw shank.

A swash plate compressor in which a drive shaft is rotatably supported in a cylinder block having a crank chamber. The swash plate is rotatably disposed on the drive shaft. Thrust bearings are individually fitted between the movable thrust receiving faces of the swash plate and the stationary thrust receiving faces of the cylinder block. As the drive shaft rotates, the swash plate likewise rotates and reciprocates a piston to compress a refrigerant gas. Annular movable ridges are formed on the front and rear side faces of the swash plate concentric around the drive shaft. Stationary ridges are formed concentrically with the movable ridges on the cylinder blocks to face the individually movable ridges. The stationary ridge has a smaller radius than that of the movable ridge. At the front and rear sides of the swash plate, the facing circumferential portions of the movable ridges and the stationary ridges are individually formed with movable and stationary thrust receiving faces for supporting the elastically deformable thrust bearings. At least one of the movable and stationary ridges are formed with escape faces so as to merge into the movable and stationary thrust receiving faces, for establishing escape faces normally between the corresponding thrust bearings. These escape faces expand and reduce the gaps when the thrust bearings are elastically deformed by the action of the swash plate due to the compression reaction forces caused by the reciprocation of the piston.

An electrical connection structure includes electrodes formed on a device side, electrodes formed on a flexible film carrier having an electrode pattern connected to a drive circuit, and an anisotropic conductive film having metal particles or metal plated particles dispersed therein, interposed between the electrodes on the device side and the electrodes on the flexible film carrier, for electrically connecting the electrodes facing each other through thermocompression bonding. The electrodes on the flexible film carrier are exposed by removing the flexible film at an electrical connection area and the length of each exposed electrode is from 1.5 mm to 2.5 mm.

In a cathode-ray tube apparatus, a deflection yoke is provided on a funnel of a tube and a pair of closed loop coils are provided on a panel and the funnel of the tube at upper and lower sides, respectively. The deflection yoke generates effective magnetic fluxes in the tube and also generates ineffective magnetic fluxes as leakage magnetic fluxes outside of the tube. Some of the leakage magnetic fluxes pass through the coils so that currents are induced in the coils and the resulting induced magnetic fluxes compensate for the leakage magnetic fluxes. Thus, the leakage magnetic fluxes passing through a space in front of the tube are reduced by the compensating magnetic fluxes from the coils.

In a cathode ray tube apparatus, a deflection yoke for generating an effective magnetic field to deflect electron beams in an envelope is provided around a funnel of the envelope. A pair of front magnetic coils are in substantially symmetrical with respect to a horizontal plane including a tube axis and a horizontal direction and are provided on a skirt of the envelope. A pair of rear magnetic coils are also arranged in substantially symmetrical with respect to the horizontal plane and are provided on the deflection yoke. Leakage magnetic fluxes generated from the deflection yoke are reduced by compensating magnetic fluxes generated from the front and rear magnetic coils.
摘要:
A swash plate type compressor comprising a swash plate accommodated in a swash plate chamber. Front and rear housings are attached to the cylinder block to form suction chambers and discharge chambers, respectively. A refrigerating medium is introduced from a suction inlet to the suction chambers via the swash plate chamber and discharged from the discharge chambers. A drive shaft is fixed to the swash plate for reciprocally moving pistons. The drive shaft has a discharge passage in the form of an axial bore formed in the drive shaft for connecting the front discharge chamber to the rear discharge chamber. The discharge passage is thus isolated from the suction system.

An in-line type color CRT electron gun having a triode and a plurality of grids, characterized in that at least one of the plurality of grids is made of a black member or a member on which a black film is formed. The time required for attaining a stable temperature of the member is reduced, thereby improving deviations in static convergence and reducing the time required for an image to be normally displayed.
