Title: Accumulator
Inventor: INOUE MASAHIKO
IPC: F16L55/04
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To provide stable performance of an accumulator under a vibrated environment. SOLUTION: A space inside a vessel 1 is divided into two chambers by means of a partition wall 6, one of the chambers being a gas chamber sealing gas, the other being an operation chamber 9 into which fluid can be introduced. The partition wall 6 is a welded bellows 6 prepared by integrally connecting inner and outer diameter portions of a plurality of annular plates 7 with each other due to gas welding, etc., forming bellows. The operation chamber 9 is formed on an inner peripheral side of the welded bellows 6, while the gas chamber 10 is formed on the outer peripheral side. A cylindrical inner wall 12 is arranged on the portion near the inner peripheral surface of the welded bellows 6 inside the operation chamber 9. Direct action of the fluid flowing into the operation chamber 9 to the welded bellows 6 is prevented by the inner wall 12, improving durability of the bellows 6.

Abstract: PURPOSE:To prevent a clutch from sliding while idling, by detecting the lowered r.p.m. of an engine below a normal value to increase a duty ratio of the intermittent driving current to flow to an electromagnetic coil of the clutch. CONSTITUTION:At a normal time the signals of an airconditioning temperature detector 8 and those of a setter 9 inside of a compartment are compared by a comparator 10 to control a transistor Q3 through a delay circuit 11 and a nonstable  multivibrator 12 for driving an electromagnetic clutch for a vehicle air conditioning device 1 through a continuous current at a starting time and through an intermittent current after starting. And when idling, the lowering of the r.p.m. thereof is detected through a detector 13 to be given to a switching circuit 16 through a monostable multivibrator 14 and a comparator circuit 15 for changing a resistance value to be inserted into the nonstable multivibrator 12 to enlarge a duty ratio thereof. Accordingly at the time of the lowered r.p.m. the supply input to the electromagnetic clutch can be enlarged to eliminate sliding for performing constant and excellent air cooling.

Title: Production of high-chromium steel using chromium ore
Inventor: NAKAYAMA KOJI
IPC: C21C5/34
Filed: 1985-06-11
Abstract: PURPOSE:To obtain a high-chromium steel with good efficiency at a high recovery rate by blowing a powder mixture composed of chromium ore and carboneous material to the fire point of a molten iron and melt-reducing the chromium ore at a high temp. CONSTITUTION:The molten iron 2 which is preliminarily dephosphorized is contained in an oxygen top furnace 1. The lance 3 is a composite nozzle which ejects the powder mixture composed of the chromium ore and carboneous material entrained in a carrier gas from the nozzle 31 positioned at the center and ejects gaseous oxygen from the circumferential nozzles 32. The powder mixture is thereby always blown to the fire point of the molten metal and the reduction reaction of the chromium ore progresses in the presence of the carboneous material. The chromium oxide and iron oxide in the ore are migrated as metal into the molten iron by the above-mentioned operation. The chromium- component to be migrated in the slag can be decreased by such method and the efficient production of the high-chromium steel is made possible.

Abstract: PURPOSE: To eliminate dispersion in precision at every measurement point by converting many impulse responses into digital signals and then by processing them.  
     CONSTITUTION: Impulse responses of microphone 4-1, sampled at the timing of signal C-1 of timing control circuit 25 and digitized by A/D converter circuit 7, are sequentially accumulated by accumulator 9 after passing through square-law circuit 8 and sent to register 10 in sequence at the timing of signal C-2, and the contents of register 10 are written at addresses of RAM11 and also inputted to register 12. The contents of register 12 are inputted to subtracter circuit 14 by way of latch circuit 13 and results of sequential subtraction from contents of RAM11 are inputted to display/recorder 19 from interface circuit 18 through RAM17. After data are selected by monitoring the reverberation waveform of unit 19, the microphone is changed over and the same process is repeated. Therefore, precision dispersion at every measurement point can be eliminated.

Title: Pulse amplitude modulating circuit
Inventor: HATTORI SEIJI
IPC: H04N5/335
Filed: 1986-06-02
Abstract: PURPOSE:To simplify circuit constitution and eliminate rounding, and to reduce phase delay by impressing a modulated wave to the power terminal of an amplifying circuit, impressing pulse for modulation to the input side of the amplifying circuit, and leading a wave to be modulated out of the amplifying circuit through its output terminal. CONSTITUTION:When pulses for modulation are at 'high', a modulating wave is applied to the input terminal Ti of a CMOSIC 2 through a resistance R1 and the input to the CMOSIC 2 enter a 'high' state because the modulating wave exceeds a threshold voltage. The input signal is therefore inverted and the output of the CMOSIC 2, i.e. the wave to be modulated goes down to 'low'. When the pulses for modulation are at 'low', on the other hand, a diode D1 turns on, the input to the CMOS IC2 goes down 'low', and the output goes up to 'high'. In this case, the input to the CMOSIC 2 generates an output almost as high as a source voltage because the input is at 'low' and the source voltage is the modulating wave which is an analog video signal at a pulse amplitude modulating circuit 1, so the output of the CMOSIC 2 is almost equal in level to the modulating wave eventually.
