Title: Large-diameter control valve
Inventor: NISHIMURA TOSHIYA
IPC: F16K1/42
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To facilitate any control at a minute open area by forming a valve element of a large-diameter control valve into a profile type of valve seat form. SOLUTION: A valve element 1 has one contact point to a valve seat 2 and it is formed into a profile shape as finely increasing a clearance along a valve seat diameter ϕd. Therefore, when a valve element 1 is lifted, a minimal opening part between the valve seat 2 and the valve element 1 shifts as finely increasing the profile along the circular arc of a radius R1 of the valve seat 2. With this shifting, opening is controlled, and a flow gain is also controlled. When the valve seat 2 is of a projection type, an end part of the valve element 1 is formed into a recess type of a radius R3 being larger in curvature than a projection part of the projection type.  With this formation, in a minute open area, an increase in a passage area to the valve opening is made to be smallness as compared with the conventional plug valve, and thus it is possible to cope with the promotion of a large diameter in the control valve.

Also, since the arithmetic result can be rewritten, another fuzzy logical operation can be performed by rewriting the arithmetic result. Thereby, a programmable fuzzy logic circuit can be obtained by rewriting the arithmetic result one after another according to a program.

Title: Reference current source device using semiconductor integrated circuit
Inventor: FUJII TOSHIAKI
IPC: G05F3/30
Filed: 1985-05-27
Abstract: PURPOSE:To control the temperature coefficient of the output current of a reference current source and to reduce the chip occupancy area, by adding a simple external circuit consisting of a variable resistor. CONSTITUTION:The collector resistances of transistors (TR) Q1 and Q2 are divided into resistances R3a/R3b and R4a/R4b respectively. A series circuit of resistances R4c, (Rx+Ry) and R3c is connected to the joint between the resistances R3a/R3b and R4a/R4b. In this case, the resistance (Rx+Ry) serves as a single variable resistor and is attached externally to a semiconductor integrated circuit. Then the resistance (Rx+Ry) is controlled to set the collector currents of the TRs Q1 and Q2 at proper levels. Thus the temperature coefficient of the output current of a reference current source is minimized. Thus the occupancy area of the reference current source can be reduced within a chip since the temperature coefficiency of the output current is controlled by an external variable resistance.

Title: Ratio type turbocharger

IPC: F02B37/00
Filed: 1990-04-29
Abstract: PURPOSE:To improve the rotational efficiency of a turbocharger by dividing a shaft provided between a turbine and a compressor into two, and meshing gears which have different sizes (diameters) each other. CONSTITUTION:In prior arts, turbochargers are constituted such that air is supplied to a mixer utilizing exhaust gas so as to burn air-fuel mixture easily. In this case, however, a combustion efficiency is not improved, since a turbine and a compressor are rotated coaxially. To eliminate the drawback, a shaft 3 provided between a turbine 1 and a compressor 2 is divided into two parts, and gears A, B which have different sizes (diameters) are meshed with each other so as to improve a combustion efficiency. For example, when the size of the gear A is set 1 while the size of the gear B is set the half (1/2) of the gear A, the diameter of the gear B becomes the half of the gear A, so that the gear B can be rotated twice as first as the gear A. It is thus possible to obtain a maximum efficiency.
