摘要:
A reading section optically reads a code from a recording medium having a portion on which multimedia information including at least one of audio information, video information, and digital code data is recorded as an optically readable code. A plurality of processing sections sequentially process the code read by the reading section and output the processed code as the original multimedia information. An operation switch designates the start of reading of the code. A control section causes one or a plurality of the plurality of processing sections to terminate a processing operation for a code which has been read by the time the operation switch is operated, and executes processing for data of the processed code in correspondence with another processing section on a subsequent stage, on the basis of the operation of the operation switch after the start of reading is designated by the operation switch.

The present invention provides parts of a rotation machine which effectively prevent particulates, such as silica, iron oxide, and other particles, contained in a gas to adhere to the rotating machines which work with the gases containing the particulates. An intermediated metal-plated film and a plated film containing fluorocarbon polymer particles provided on the intermediate metal-plated film are deposited on the surfaces of moving blades used in a steam turbine. The plated film containing the fluorocarbon polymer particles includes fluorocarbon polymer particles made of any of Ni-based metals and a plated matrix, and some of the fluorocarbon polymer particles are exposed at the surfaces of the plated matrix.

The present invention is to provide a method of compensating the wavelength dependence of birefringence of an optical part (B) which comprises using a film (a) made of a (co)polymer (α) obtained from at least one olefin selected among 4-methyl-1-pentene, 3-methyl-1-pentene, and 3-methyl-1-butene as a (co)monomer ingredient.
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.

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.

A semiconductor device including a buffer layer 32 on n-GaAs, a clad layer 31, a wave guide layer 30 and a carrier block layer 29 of n-AlGaAs, a side barrier layer 28 of non-doped AlGaAs, an active layer 27 which is formed by two non-doped GaAs quantum well layers and a barrier layer of AlGaAs, a side barrier layer 26 of non-doped AlGaAs, a carrier block layer 25, a wave guide layer 23 and a clad layer 22 of p-AlGaAs, and a cap layer 21 of p-GaAs are grown in this order. 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.

The present invention has an object to provide a steel for a chimney or a gas duct, which is excellent in pitting resistance and rust adhesion in a corrosive environment caused by combustion waste gas in a plant in which the combustion of natural gas occurs. Pitting resistance and rust adhesion are remarkably improved in the steel of the present invention which steel is prepared by using a 5% Cr steel as the base, while reducing an impurity sulfur to not more than 0.010 wt. %, adding titanium within a range of 0.005 to 0.05 wt. %, and further adding nickel alone within a range of 1.0 to 2.5 wt. %, or adding molybdenum alone within a range of 0.10 to 1.0 wt. %, or adding in combination therewith trace amount of copper or molybdenum within a range of 0.10 to 1.0 wt. %.
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.
