Abstract: A valve timing adjusting device includes: a first rotor rotating integrally with a crankshaft; a second rotor integrally secured to an intake or exhaust camshaft; and an engaging cavity provided in one of the first rotor and the second rotor. A lock pin is housed in a housing hole provided in the other of the first rotor and the second rotor, protruded by the energizing force of an energizing device at the time of hydraulic pressure reduction, to thus abut on the wall of the engaging cavity from an oblique direction to give a relative rotating force to the first rotor and the second rotor.

Abstract: A first rotor integrally fixes a housing having the bearing of a camshaft, a case, which internally has a plurality of projecting shoes and which forms hydraulic chambers between these shoes, and a cover, which covers the hydraulic chambers, and the first rotor rotates integrally with a crank shaft. A second rotor has a plurality of vanes each dividing the hydraulic chamber into an advanced-angle hydraulic chamber and a retarded-angle hydraulic chamber, can rotate by a predetermined angle within the first rotor, and is integrally fixed with an intake or exhaust camshaft. A groove accommodating an energizing part, opposed to the shoe of the first rotor and to the vane of the second rotor, is provided on the opposite side to the housing.

Abstract: A hydrodynamic bearing device in which an introducing minimum clearance for causing capillary phenomenon is formed from the location in the proximity of the opening of a communicating path to the open end of the bearing hole in between the cover and the end face on the open end of the sleeve so that the operating fluid from the communicating path in the sleeve flows into the bearing hole by the capillary phenomenon; a vent hole leading to the outside air is formed on the cover; a fluid storage space for storing the operating fluid is formed on the inside surface of the cover or the end face on the open end of the sleeve to communicate the introducing minimum clearance and the vent hole in the circumferential direction; and the air bubbles separated at the fluid storage space are exhausted outward from the vent hole.

Abstract: Due to the fact that a regulator engages with an engagement aperture when hydraulic pressure is low due to unexpected decreases in engine rotation frequency during relative turning of a valve timing control device, the valve timing control device re-enters a regulated state. Control and running of regulation or release of relative rotation position of the valve timing control device by a regulator are performed by an external device distinct from the valve timing control device.

The solenoid valve fixing structure includes a recessing portion (6) disposed on an intake manifold (5), for receiving a solenoid valve (1), and a fixing member (4) having a fixing part (4a) to be fixed to the solenoid valve, a deformable lip (4d), which is an elongated portion of the fixing part to contact elastically with the recessing portion, and an insertion lip (4f), which is another elongated portion of the fixing part and is to be inserted into the recessing portion (6). A solenoid valve (1) can be fixed to the intake manifold (5) strongly and promptly.

Abstract: The present invention relates to a solenoid valve fixing structure. In an apparatus for suppressing evaporated fuel gas emission, of the prior art, the solenoid valve is fixed to a frame of a vehicle independently from the fixing of a check valve or an air filter. Hence, there are drawbacks, for example, that the number of the fabrication elements is large, and the fabrication performance is small.The present invention propose a solenoid valve fixing structure constructed as a module comprised of a solenoid valve, a check valve and an air filter. Namely a solenoid valve 10 and a check valve 8 are fixed onto a cover 3 of an air filter 1. The number of the fabrication elements can be reduced. The size of the apparatus can be made small, by using the module.

Abstract: In a clamping circuit comprising a voltage comparator for comparing an input signal voltage supplied to the signal input terminal and a reference voltage, a clamping circuit of the present invention comprises a bias voltage supplying circuit and a switch circuit inserted between the bias voltage supplying circuit and the signal input terminal. The input signal voltage is compared with the reference voltage by the voltage comparator, and the switch circuit is ON/OFF-controlled on the basis of the comparison result. When the switch circuit is enabled, a bias voltage supplying circuit is supplied to the signal input terminal, and the input signal voltage is clamped at a voltage equal to the reference voltage. When the switch circuit comprises a CMOS transfer gate, a voltage drop does not occur across the switch circuit regardless of the value of the bias voltage.
