Title: Rectangular wave oscillation circuit
Inventor: YAMAGUCHI CHIKATSUGU
IPC: H03K3/0231
Filed: 1990-10-22
Abstract: PURPOSE:To employ a single power supply operational amplifier and to decrease the frequency fluctuation against power supply voltage fluctuation by providing a bias capacitor supplying a discharge current to an output terminal through a noninverting input terminal when the output terminal is at a low level to the oscillation circuit. CONSTITUTION:A voltage -Vi at an inverting input terminal rises by charging of a C1 through a resistor r2 through the inversion of an output voltage from a low level to a high level. On the other hand, a voltage +Vi at a noninverting input terminal rises through resistors r1, r2 to charge a bias capacitor C2. When the voltage -Vi exceeds a voltage +Vi, the voltage Vo decreases its level and the voltage -Vi decreases by the discharge through a diode D. Simultaneously, a voltage Vp at a node P is decreases through the capacitor C1 and further, the capacitor C2 is discharged through the resistors r1, r2, r3 and the voltage +Vi is more decreased. Just after the voltages -Vi, +Vi are equal to each other, the output voltage Vo is inverted to be a high level.

Title: Pll frequency synthesizer and device using the synthesizer
Inventor: MATSUI HIROAKI
IPC: H03L7/183
Filed: 1994-11-18
Abstract: PURPOSE: To provide a PLL frequency synthesizer which can shorten the waiting time needed for setting a dividing ratio and also can quickly set the dividing ratio. CONSTITUTION: The input signal received from an input terminal 2 and the reference signal received from an input terminal 6 are divided by a counter 8 and a reference counter 9 respectively. The output signals of both counters 8 and 9 are compared with each other by a phase comparator 10, and this comparison output is supplied to an output terminal 13 or to an output terminal 12 via a switch 11. If the setting data are inputted from an input terminal 3 while an LE (load enable) signal is kept at 'L', the setting data are fetched by a shift register 7. Then the LE signal is changed to 'H' and a latch clock is outputted from a latch clock generating circuit 15 at the rise of the LE signal. Thus the setting data are transferred to the counters 8 or 9 from the register 7, and the dividing ratios of both counters are changed.  The switch 11 is turned on and the terminal 12 is effective while the LE signal is kept at 'H'.

Title: Production of metal fine powder
Inventor: SATO YOSHITOMO
IPC: B22F9/08
Filed: 1990-10-22
Abstract: PURPOSE:To easily obtain a metal fine powder of small average particle size without variation in the particle size by supplying a heated high pressure gas to an injection nozzle to prevent condensation of the atomizing gas after the gas passed thorough the throat part of this nozzle. CONSTITUTION:A downflow 25 of molten metal 14 is cooled and solidified by injecting high speed gas jet 24 through plural numbers of injection nozzles (not shown in the figure) at the bottom of a nozzle device 17. When high pressure atomizing gas is supplied from a gas reservoir tank 1 to the injection nozzle, the gas changes into a high speed flow while passing through the throat of the nozzle and then rapidly expands to decrease its temp. after passing through the nozzle. During this process, by heating the high pressure gas with a heater device 2 before supplying to the nozzle device 17, the gas temp. decreases to above its condensation temp. Consequently, this prevents variation of the flow rate of the gas jet 24 and energy decay of the high speed gas. Therefore, a metal fine powder of small average particle size can be obtd. without variation of particle size.

Title: Method and device for analyzing electronic circuit operation
Inventor: INOUE YASUAKI
IPC: G06F17/50
Filed: 1993-11-16
Abstract: PURPOSE:To realize a DC operating point analysis method capable of quickly obtaining the DC operating point of an electronic circuit and to analyze the DC operating point of a large-scale analog circuit. CONSTITUTION:The circuit equation system of the electronic circuit is constructed by a correction node solution method (step S2-1.) Based on the obtained correction node equation system, a homotopy equation system is constructed by using Newton homotopy (step S2-2.) Then, an integral curve in the homotopy equation is tracked by the method of an oblique cylinder (step S2-3.) Since the method of the oblique cylinder can maintain the sparseness of a Jacobian matrix high, the integral curve is tracked at a high speed. Since the homotopy equation system is also constructed by using the Newton homotopy based on the correction node equation system, the sparseness of the Jacobian matrix is maintained and the integral curve of the equation system is surely tracked. Thus, the global convergence of a continuous method is guaranteed.

Filed: 1988-11-11
Abstract: PURPOSE:To reduce running agent ratio and to increase a projection height of special section patterns by controlling respective drafting amounts in work roll stands in the final stage and in the preceding stage by following a decided procedure. CONSTITUTION:At rolling for a range of 3-10m length in the top part of a steel sheet, a drafting amount in a work roll stand FL is reduced than a usually required amount and drafting amount in a work roll stand FL-1 in the preceding stage is increased than a usually required amount. Then, for a period of time from bitting the steel sheet top to a time after a required period of time passed, a roll gap amount is maintained and the top part of 3-10m length passes through in the required period of time. After passage of the steel sheet top range, a draft amount in the work roll stand FL is increased and a draft amount in the preceding stage roll stand FL-1 is reduced in correspondence to the increased amount in the stand FL to obtain a product thickness of required value. Hence, running against ratio of a strip generated in initial rolling time is reduced and a projection height of a special section patterns is increased.
