Filed: 1990-05-14
Abstract: PURPOSE: To provide a high-performance, single-stage pressure regulating valve by forming, over an orifice tube including a boost means imparting pressure to the other side of a diaphragm means, a gap of a smaller opening than the extension of the orifice tube. CONSTITUTION: A formed cam stem 26 is directly actuated by pressures to an adjustment screw 36 and a diaphragm 20 and a valve disk 60 is linearly moved into a valve seat 52 by a cam contour 33 to open and close a flow passage from a suction port 22 to an exhaust port 24 to maintain downstream control pressure within a lower chamber 18. An orifice tube 50 having a valve seat 52 has a boost cap 80 removably provided at its tube end, and since the orifice 82 thereof is remarkably smaller than the diameter of the orifice tube 50 and greater than the diameter of the valve seat 52, a controlled boost effect can be obtained and the diaphragm 20 can be exposed to a large-volume gas flow chamber and be protected from excess pressure. Thus, a low-cost, single- stage gas pressure regulating valve suited for a wide range of applications can be obtained.

Title: Mechanical supercharger of internal combustion engine
Inventor: OBATA HARUMASA
IPC: F02B29/00
Filed: 1982-07-15
Abstract: PURPOSE:To prevent a transmission belt mechanism and a supercharger from being placed suddenly under load when supercharging operation is started by gradually placing the supercharger under load after rotating it in no-load condition. CONSTITUTION:During idle operation or light load operation, since opening of an intake air throttle valve 26 is small and a supercharge control valve 52 is in an opened position, intake air is sucked into an engine via a bypass duct 50. When the engine load is increased and the intake air throttle valve 26 reaches the first set opening, an electromagnetic clutch operates to put a vane pump 28 in turning. Since the above-mentioned supercharge control valve 52 is opened, no substantial load is placed on the vane pump 28. When the intake air throttle valve 26 exceeds the second set opening, said valve 52 is gradually closed and perfectly closed at last, and the bypass duct 50 is shut off, the vane pump 28 being operated in full-load condition.

IPC: G09F9/30
Filed: 1991-04-24
Abstract: PURPOSE:To provide uniformity of brightness distribution in an EL emitting end surface even with ununiformity of film thickness and film quality in an EL emitting part and a light waveguide path by providing a structure such that the EL emitting part is provided on a substrate with a length thereof changed in accordance with a position in the lengthwise direction of an EL element. CONSTITUTION:An EL element is prepared to measure brightness distribution by using a low-expansion glass as a substrate 1, SiON film as a light waveguide layer 2 and layer constitution of order successively of an ITO electrode/Si3N4/ZnSi3N4/AI electrode from a waveguide path side as an EL emitting part 3. Measurement is performed by a luminous energy sensor to transmit the luminous energy one by one to an arithmetic device while moving the luminous energy sensor successively in the lengthwise direction of the EL element, and a length in a light emitting direction of the EL emitting part in each position is calculated by the arithmetic device. An etching shape of the part 3 is changed so that the part 3 is lengthened in a part of low brightness and shortened in a part of high brightness to obtain an element of small unevenness of brightness in the lengthwise direction of the EL element. In this way, the EL element of uniform brightness in the lengthwise direction of the EL element can be obtained.

Title: Flow cell apparatus
Inventor: MATSUMOTO MASAYOSHI
IPC: G01N15/06
Filed: 1993-05-25
Abstract: PURPOSE:To improve the inspecting accuracy by forming the flow of a sample liquid thin, wide and flat, forming a reduced passage part on the upstream side and forming a parallel flow connected to the reduced passage part at a measuring part, and providing a speed reduction passage part after the measuring part. CONSTITUTION:A flow passage of a flow cell 1 comprises a parallel passage part 1a, a reduced passage part 1b, a measuring passage part 1c and a speed reduction passage part 1d. A sample liquid including particles 20 to be inspected running in a direction of an arrow 25 is discharged into the passage from a nozzle 3, and becomes a sheath flow surrounded by a sheath liquid from a direction of an arrow 24. The sheath flow flows in the flow cell 1 at a constant speed. The sectional area is reduced only in the thicknesswise direction from a discharge port 19 to a photographing part 21, so that the sheath flow is increased in speed and stabilized. For instance, a stable sample flow 23 of, e.g. 1000mm/sec. or more at high speeds is obtained whereby the photographing accuracy is improved. Moreover, since the sample flow 23 discharged from the nozzle 3 is reduced uniformly in the thicknesswise direction, thereby forming a uniform and flat flow, the photographing accuracy is improved also by this arrangement.
