    摘要: A composite control valve is constructed by a valve housing, first and second diaphragms mounted to the valve housing and disposed to be opposed to each other, a negative pressure working chamber defined between the first and second diaphragms to communicate with a negative pressure generating section in an engine, a first control valve adapted to be opened and closed by advancing and returning of the first diaphragm, and a second control valve adapted to be opened and closed by advancing and returning of the second diaphragm. The first control valve is incorporated into an air vent system for a fuel tank, and the second control valve is incorporated into a fuel passage system extending from the fuel tank to a fuel supply section in the engine. Thus, upon stoppage of the operation of the engine, not only the fuel passage system but also the air vent system leading to the upper space in the fuel tank are blocked simultaneously, thereby preventing release of an evaporated fuel generated in the fuel tank to the atmosphere.

    摘要: A semiconductor device that quickly saves data stored in an area to which power is supplied intermittently. Power is supplied intermittently to a first area. Power is supplied continuously to a second area. A memory is located in the second area. A save circuit saves data used in the first area in the memory before the supply of power being stopped. A restoration circuit restores data which has been saved in the memory to a predetermined circuit in the first area. A power supply control circuit supplies power to the memory if data has been saved in the memory. Otherwise the power supply control circuit stops the supply of power to the memory.

    摘要: In an engine of a compression-ratio variable type, a subsidiary rod and a piston connected to a crankshaft are connected to each other through a connecting rod, and an eccentric shaft mounted at an eccentric location on a support shaft turnably carried in an engine body and the subsidiary rod are connected to each other through a control rod, so that the compression ratio of the engine is changed by changing the turned position of the support shaft. The engine further includes a one-way clutch mounted between the support shaft and the engine body for limiting the direction of turning of the support shaft. The turned position of the support shaft is limited selectively at a plurality of points by a turned-position limiting means, and a load applied to at least one of the support shaft and the turned-position limiting means is moderated by buffering means.

Inside the wave guide layer 23, current blocking layers 24 having a lower refractive index and higher Al-composition than that of the wave guide layer and sandwich a strip-shaped active region 34. This creates a refractive index difference between the active region 34 and buried regions 33 in which each of the current blocking layers 24 exists, thereby forming a refractive index guide structure. Thus, it is possible to obtain a high-output semiconductor laser device of the refractive index guided type which is easy to manufacture.

    摘要: A fuel supply system for a general purpose internal combustion engine is equipped with a sub-fuel tank that retains gasoline fuel supplied from a main fuel tank and houses the high-pressure pump in its interior. In other words, the pump is immersed in the gasoline fuel retained in the tank, so that if an air pocket should occur in the fuel supply pipe between the main fuel tank and pump, the air will be discharged from the sub-fuel tank to the exterior through a fuel return pipe etc., thereby ensuring that the pump does not suck in air. Since fuel injectors can therefore inject gasoline fuel immediately, starting performance is enhanced.
