Abstract:
A variable capacity wobble plate type compressor with a lubricator for oil-lubricating wobble plate bearings in a crankcase interior, which has an oil dam formed in an entrance of the central bore of a drive plate rotatably mounted on a compressor drive shaft for catching and preserving a lubricating oil scattered by a non-rotary wobble plate during wobbling in the crankcase interior and an oil supply conduit for supplying the preserved oil in the oil dam to the thrust and radial bearings by which the wobble plate is supported on the drive plate.

A variable displacement compressor with a variable angle non-rotary wobble plate, having a control valve assembly which includes a pressure detecting unit for detecting a change in a pressure in the compressor crankcase and a single valve mechanism arranged in a communication passageway between the crankcase and the compressor suction chamber and able to control communication between the crankcase and the suction chamber in association with a pressure changing signal from the pressure detecting unit so that the pressure in the crankcase is maintained at a predetermined pressure value.
Abstract:
A suspension device includes a wheel supporting member configured to rotatably support a wheel. Two links respectively link the wheel supporting member and a vehicle-body side member and are disposed substantially in parallel in a vehicle width direction. At least one projecting portion extends from at least one of the two links towards the other link, and an elastic linking portion links the projecting portion of one of the links to at least one of the other link and the projecting portion of the other link. A toe angle adjusting device is configured to input a force in a direction oriented backward in the vehicle forward-backward direction to the wheel supporting member to adjust a toe-in angle of the wheel.
Abstract:
A variable displacement swash plate type compressor having a cylinder block in which a drive shaft is centrally and axially extended so as to mount thereon a swash plate assembly to drive pistons reciprocally arranged in a plurality of cylinder bores arranged circumferentially about the drive shaft. The swash plate assembly has a rotary swash plate and a non-rotary wobble plate in a crankcase formed in the cylinder block and a mechanism for changing the wobble angle of the swash plate and the wobble plate by turning them about an axis extending at a right angle to the rotating axis of the drive shaft and passing through points which come into registration with respective centers of connection of connecting rods of the pistons and the wobble plate when the pistons are at the top dead center of their strokes within the cylinder bores.

Abstract:
In order to increase performances of an iron oxide-potassium oxide system catalyst to be used for an alkyl aromatic hydrocarbon dehydrogenation reaction in the presence of steam, there is provided an alkyl aromatic hydrocarbon dehydrogenation catalyst wherein a little amount of titanium oxide is added by the mixing and kneading method or by the preceding addition to iron oxide in the production of the iron oxide-potassium oxide system catalyst to be used for the alkyl aromatic hydrocarbon dehydrogenation reaction in the presence of steam. The iron oxide-potassium oxide system catalyst is allowed to contain a little amount of titanium oxide, whereby an activity can be remarkably increased, as well as a selectivity in the same conversion ratio can also be improved in the alkyl aromatic hydrocarbon dehydrogenation reaction, and further the obtained catalyst exhibits stable performances with time on stream.
Abstract:
In a wobble plate type compressor having a wobble plate that converts a rotational motion of a rotatable drive plate having a variable angle of inclination to a linear reciprocating motion of a piston, a method of controlling the wobble plate type compressor to control a displacement of the compressor by changing an angle of inclination of the wobble plate according to a pressure difference between a pressure in a crankcase chamber acting on one side of the piston and a suction pressure acting on the other side of the piston. A solenoid-operated control valve is disposed in a pressure control passage extending from a discharge chamber to the crankcase chamber. The control valve is opened and closed to control the above-mentioned pressure difference, thus controlling the angle of inclination of the wobble plate. An opening of the control valve is increased during a period in which the displacement of the compressor is to be reduced, according to a displacement rapid reduction command signal. In an initial stage of this period, the opening of the control valve is made temporarily wider than in the remaining period.
