Title: New charge temperature control system supercharger in engine
Inventor: MIYAZAKI SOICHIRO
IPC: F02B29/04
Filed: 1984-08-14
Abstract: PURPOSE:To provide optimum cooling of new charge according to the running condition of an engine to restrain the exhaust of noxious exhaust and intensify supercharging effect by changing over air supplied from a supercharger to any of a supplied air cooler, bypass pipe and water or alcohol injection unit. CONSTITUTION:Air pressurized by a compressor 6 of a supercharger 4 is selected by a change-over valve 12 for changing over flow paths to a new charge cooler 9 or a bypass pipe 11. When the signal from a new charge temperature detector 17 shows low temperature, a control unit 18 operates the change over valve 12 to open the bypass path 11 so that uncooled air is supplied to an engine. When new charge temperature is further raised, the change-over valve closes the bypass path 11 to open the flow path to the new charge cooler 9 so that the new charge is cooled to be sent to the engine. When the new charge temperature is furthermore raised, water or alcohol 15 is injected from a tank 16 through a nozzle 13 by a pump 14 to maintain the new charge temperature at an optimum value.

Abstract: PURPOSE:To manufacture laser elements wherein single longitudinal oscillation is obtained at a high yield rate by optimizing the range of a normalized bonding coefficient kappaL that is proportional to the product of the depth of a diffraction grating and the length of a resonator and the range of a reflectivity at an end surface, in a distributed feedback type laser element having the diffraction grating whose phase shift part is located in the vicinity of the center of the inside and a lightguide structure. CONSTITUTION:A lightguide has a periodic structure in the direction of the axis of a resonator. One or more phase shift regions are formed in the distances from the center of the resonator having said periodic structure in both directions. The distance is less than 20% of the length of the resonator. Or a deformed lightguide region corresponding to said phase shift region in an equivalent mode is provided. The reflectivities at both end surfaces are 5-15%. The value of the product kappaL of a bounding coefficient (kappa) and the length L of the resonator is set at 0.6<=kappaL<=1.0. Within the ranges of 0.6<=kappaL<=1.0 and 5<=R(reflectivity)<=15%, a yield rate of 30-50% is obtained in the ranges characterized by relatively easy manufacture and gentle conditions can be obtained. When the reflectivities at both end surfaces are largely different, the trend becomes different. However, there is no large difference within the ranges of above described manufacturing conditions.

Filed: 1981-10-26
Abstract: PURPOSE:To prevent the occurrence of an uncertain output, by converting and delivering the output of a parallel comparison type A/D converter after converting the output once into a gray code. CONSTITUTION:The analog input voltage VS is fed to comparators 30-37 having different levels of comparison reference voltage. Then a logical circuit 50 detects the boundary between ''1'' and ''0'' for the outputs of the comparators 30-37 and then generates the corresponding gate outputs. In response to this gate output, a 3-bit gray code is delivered from an ROM type code converting circuit 151. The gray code varies successively by just a bit and is uncertain to an intermediate input that is hard to be quantized and therefore produces no  faulty output. The gray code output is converted into a binary code through the  2nd code converter 251 and then delivered.
