A pulley structure having a first rotating member that is rotatable around a first axis. A second rotating member is rotatable around the first axis and in at least partial axial coincidence with the first rotating member. A spring containing chamber is defined between the first and second rotating members. A spring, having axially spaced first and second ends defined by coils, extends around the first axis. At least one coil at each of the first and second axially spaced ends of the spring is radially biased relative to the first axis to thereby be frictionally held against each of the first and second rotating members to thereby allow forces generated by relative rotation between the first and second rotating members to be transmitted through the spring.

Pulley structure

A pulley assembly having first and second members. The first member is capable of cooperating with a power transmission belt to drive/be driven by the belt. The first member is movable guidingly relative to the second member around a first axis. A coil spring has a length and a circumference and a first portion attached to the first member and a second portion attached to the second member so that a force tending to move the first/second member around the first axis is transmitted through the coil spring to the second/first member. At least one of the first and second members has a groove bounded by a surface into which the respective portion of the coil spring is fit. The respective portion of the coil spring is clamp fit within the groove.

Pulley assembly

An elastic member made of, for instance, a rubber material, is fixed to a piston member of a lockup clutch. A wet friction facing is fixed to the elastic member. The elastic member provides a cushioning effect when the lockup clutch is engaged for controlled slippage.

A modular clutch includes a flywheel 2, a clutch cover assembly 3 and a clutch disk assembly 4, which form a single module that in one embodiment is installed directly onto the crankshaft of an engine, and in an alternate embodiment is attached to a flex plate. The modular clutch is configured to be installed and replaced as a unit. The clutch cover assembly 3 has a clutch cover 21, a pressure plate 22 and diaphragm spring 23. The clutch disk assembly 4 has a clutch engagement portion 31 made of a metallic sintered body.

Modular clutch

By the selective use of a homogeneous stable precursor solution in which no polymerization reactions immediately occur and which contains aromatic compounds such as pyrrole, thiophene, aromatic amines or their derivatives, oxidizing agents, and solvents, as a precursor solution of conductive polymer film, a homogeneous and tough conductive polymer film can be obtained when the said precursor solution is cast on a substrate and the solvents are evaporated to remove.

Method for the preparation of conductive polymer film

Polymers of 3,4-substituted pyrrole compounds and their preparation

A fully automatic transmission for use in automobiles requires the use of only a single manually operable switch in the vehicle compartment for selecting the travelling direction. All other functions of the transmission, namely the selection of the speed range, including neutral and the application of a parking mechanism are performed by a hydraulc control system in combination with an electronic control system operating according to a predetermined process.

Vehicular automatic speed change gear assembly

An automatic vehicle transmission is operated simply by driver selection of a forward or backward switch, utilizing an electric and hydraulic control system to effect speed changes among the various forward speeds, neutral and park. Also, during a shift, a solenoid valve is used to temporarily lower the pressure to prevent undue shift shock.

Automatic transmission for vehicles

A control device for regulating the amount of collected fuel and purge air which is delivered to the combustion chamber of an internal combustion engine in addition to its usual mixture of combustion air and fuel includes a valve element which is connected for operation in accordance with the pressure conditions of the fuel intake pipe and carburetor of the internal combustion engine to provide a flow rate of the collected fuel and purge air which is proportional to the flow rate of the usual fuel and air mixture. The device includes a valve body having a diaphragm dividing the interior and which carries a needle valve on one side which is adapted to seat in a valve seat of a line connected to the engine inlet. This same side of the diaphragm is also connected to a line which is adapted to receive accumulated or collected vapors, for example, from the fuel tank or the crank case. The opposite side of the diaphragm is biased by a spring to provide an initial closing action on the needle valve but this biasing force may be overcome by the negative pressure which is conducted to this portion of the body chamber by a sensing line which is adapted to be connected to the carburetor at the location of the venturi.
