Abstract: A fiber reinforced plastics comprises a resin and chopped strands dispersed in the resin, wherein the chopped strands comprise glass fiber chopped strands composed of cut assemblies of glass filaments and high elastic chopped strands composed of cut assemblies of high modulus inorgtanic filaments having higher elastic modulus than the filaments and having 3000 or less number of assembled filaments. By this arrangement, the both chopped strands are closely and uniformly dispersed in the resin and the force interaction between the both chopped stands are enhanced. The resultant plastics has remarkably improved strength and fatigue durability, and higher rigidity than conventional ones.

Thus, the exhaust gas processing apparatus of this invention exhibits improved exhaust gases purifying abilities, even at relatively low temperatures, and less pressure drop.

Abstract: A composite material comprising a resin other than polyamide resin and a layered silicate dispersed therein, said layered silicate having a layer thickness of 7 to 12 .ANG. and an interlayer distance of 30 .ANG. or above. Owing to the layered silicate uniformly dispersed in the resin matrix, the composite material is superior in mechanical characteristics and heat resistance. It also has good water resistance and chemical resistance.

Abstract: The improved structure of an inductor with an amorphous sheet core and a winding has been found. A core assembly has a pair of housing halves made of non-magnetic material with U-shaped track, in which a laminated amorphous sheet is mounted. The ends of the halves are inserted in a winding so that the ends of the cores abut with each other directly or through a gap spacer. The core halves are pressed by spring action to assemble the inductor. The core halves are produced by the steps of winding an amorphous sheet to a coil, inserting the coil in the track of the housing, and impregnating the coil with plastics.

Abstract: In order to reduce the electric power consumption of a battery operated forklift, a terminal of a motor for driving a hydraulic pump of a power steering system is connected to a terminal of a field coil of a wheel drive motor of the battery operated forklift. Thus, an electric power current for the motor of the power steering system is supplied only when the wheel drive motor is operated.

Abstract: A method and apparatus for exhaust gas recirculation for an internal combustion engine in which exhaust gas is recirculated through a recirculation passage connecting the exhaust passage of the engine and the intake passage of the engine. A vacuum-response type recirculation control valve is disposed in the exhaust gas recirculation passage to operate in response to vacuum detected at a vacuum detection port located in the intake passage in the vicinity of a throttle valve. A vacuum tank is connected through a solenoid-actuated change-over valve to the vacuum passage interconnecting the vacuum detecting port and the recirculation control valve, the vacuum tank being in communication with the intake passage downstream from the throttle valve through a check valve.

Abstract: A device for cross-linking of coating material such as rubber or plastic having a vertical or inclined cross-linking tube including a heating portion and a succeeding cooling portion, said heating portion comprising at the side thereof a gas circulating passage having a gas supply device, a gas heating device, a gas cooling device and a filter, said gas circulating passage communicating with an exhaust port above the heating portion and with a gas supply port below the heating portion so that the gas circulate in a direction opposed to the traveling direction of a conducting strand passing therethrough, whereby said conductive strand is heated and cross-linked while residue emitted from the coating material of said conductive strand is effectively removed.

Abstract: When a plasma display panel driven by a conventional driving circuit therefor, spurious pulsed voltages appear across discharge cells which are in the vicinity of a selected discharge cell. A method and apparatus for driving a plasma display panel in a time division manner includes supplying the plasma display panel electrodes with suppress pulse trains for cancelling the spurious pulse voltages coupled thereto. The suppress pulse trains are in synchronism with, and of a polarity opposite to the driving pulses that are supplied to such electrodes in accordance with time division principles.
