Abstract: Two flat fiber bundles of non-twisted filaments are arranged in an overlapped relationship or in a parallel and adjoining relationship, and held by a gripper at two points spaced apart from each other in the filament-extending direction. Compressed air is injected from a nozzle to the overlapped portion of the fiber bundles between the holding points at a plurality of positions arranged in the direction transverse to the filament-extending direction to cause the adjacent filaments to be entangled. The nozzle is moved across the fiber bundles while injecting air. Filaments are thus opened and rotated by the injected air, and thus entangled. A fiber bundle joining apparatus includes support sections and a receiving section provided in a base, a gripper cooperating with the support sections to grip overlapped ends of fiber bundles therebetween, a nozzle, and a regulating member to temporarily hold the fiber bundles and to allow the lower fiber bundle to be slackened.

Abstract: A second processor 6 inserts data to be transmitted and pointer information into a data packet and transmits the data packet at step S20 and then determines whether an acknowledgement from the receiving party has been received at step S22. If no acknowledgement has been received, a determination is made as to whether the number of re-transmissions is equal to or less than a predetermined re-transmission number at step S32. If the re-transmission number is equal to or less than the preset value, then a data packet 16 with the same data is transmitted at step S20. However, if the re-transmission number has reached the preset value, then the number of data bits per data packet is reduced at step S36, and a data packet with reduced data is transmitted at step S20.

Abstract: An apparatus for restricting pivoting of a pivotal axle in a forklift. The forklift has an axle that is supported pivotally relative to a body frame. A damper is arranged between the body frame and the axle to permit and restrict pivoting of the axle. An electromagnetic valve locks the damper to restrict pivoting of the axle. The axle is free to pivot when the pivot angle of the axle relative to the body frame exceeds a predetermined reference angle. A controller refers to the pivot angle and other factors relating to vehicle stability when deciding whether to restrict pivoting of the axle.

Abstract: A driving force transmission unit consists of a gear unit engaging with the motor axes of two AC motors, and a bevel gear for transmitting the driving forces of the two AC motors to an axle.

A drive shaft is supported in the housing. A radial bearing is located in the housing. A holding bore houses the rear end of the drive shaft and the radial bearing. The holding bore is connected to a holding space. A passage connects the holding space and the suction chamber. A restricting member is located in the holding space. The restricting member restricts axial movement of the drive shaft and divides the holding space into a first region and a second region. A clearance is formed between the restricting member and the valve plate assembly. The clearance disappears when the pressure of the crank chamber is increased rapidly.

Abstract: A compressor includes a discharge chamber and a retaining passage, which is located downstream of the discharge chamber. A control valve controls the displacement of the compressor in relation to the pressure difference between a first pressure monitoring point in the discharge chamber and a second pressure monitoring point in the retaining passage. A pressure introducing passage connects the retaining passage to the control valve. The pressure introducing passage has an opening to the retaining passage. An inlet member is located in the retaining passage to cover the opening. The inlet member has a pressure introducing port that functions as the second pressure monitoring point. The pressure of the refrigerant in the retaining passage is supplied from the pressure introducing port to the control valve through the pressure introducing passage. The inlet member easily alters the position of the pressure introducing port in the retaining passage.

Abstract: A cooling apparatus for a fuel cell system having high cooling efficiency. The cooling apparatus includes a chemical heat pump circuit using isopropyl alcohol, acetone, and hydrogen gas as a heat carrier. The chemical heat pump circuit includes an endothermic device incorporated in the fuel cell and an exothermic device for releasing heat from the circuit. The temperature of a heat carrier is increased to a first temperature by the heat of the fuel cell. The chemical heat pump circuit uses the heat of the heat carrier after it is heated to the first temperature to heat the heat carrier to a second temperature, which is higher than the first temperature. The heat of the heat carrier is used for other useful purposes or is simply desorbed. After the heat carrier is heated to the second temperature, the heat carrier is easily cooled by a cooling fan. Thus, the cooling apparatus has a high cooling efficiency.
