Patent JP-S5639602-A (JP)
Title: Oscillating circuit
Inventor: KATAGAWA YUTAKA
IPC: H03B5/36
Filed: 1979-09-07
Abstract: PURPOSE:To shorten switching time by shortening the turn-off time of an output transistor by rapidly discharging the charge of the base of the output transistor by way of a current Miller circuit that includes a diode. CONSTITUTION:Between the base and collector of oscillating NPN transistor  (TR)Q11, quartz oscillator XTL1 is connected to form a B-E earthed type oscillator and its emitter is direct grounded. With buffer TRQ15 on, electric current to flow through diode D12 appears at the emitter of load TRQ16 in the output stage of the oscillating circuit by the current Miller circuit, and consequently electric current  flowing to the base of output TRQ17 turns on TRQ17, whose base is accumulated  with charge. With TRQ15 off, on the other hand, the charge of the base of TRQ17 is  rapidly discharged via TRQ16 through the operation of the Miller circuit of TRQ16  and diode 12. Thus, the turn-off time of TRQ17 is shortened, so that the switching time can be shortened.

Title: Method for impregnating porous material
Inventor: FUJIMOTO KENICHIRO
IPC: C04B41/88
Filed: 1992-04-09
Abstract: PURPOSE:To impregnate a sufficient amount of a metal into pores of a porous material. CONSTITUTION:A molten metal is impregnated under pressure into a porous material immersed in the molten metal and the porous material impregnated with the metal is pulled up from the molten metal while maintaining the pressure state as it is in a temperature range from the melting point of the metal to be impregnated to a temperature 120 deg.C higher than the melting point. Consequently, a composite material having an extremely high impregnation ratio of the metal in the porous material is produced even by using a metal having low wetting to the porous material and even without carrying out a specific pretreatment.

Title: Speech detecting device
Inventor: FUKUSHIMA MINORU
IPC: G10L25/21
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To precisely detect whether a reference signal contains a speech signal or not in a system presenting a large acoustic coupling gain or under a condition with a high background noise level. SOLUTION: A background noise power estimating and switching part 4 stops an estimation processing in a background noise power estimating part 2 when the ratio of an acoustic coupling gain component contained in a reference signal Vx is large. This makes a background noise power estimation value Pn becomes close to a value approximating a background noise power around a microphone 10 regardless of the phone call state. Thus, this device reduces a deterioration of a speech detection performance caused by a turn-around of a background noise on a far side to the microphone 10 in a system with the microphone 10 and a speaker 11 in a short distance causing a large acoustic coupling gain, and precisely detects whether a reference signal contains a speech signal or not under a condition with a high background noise level.

Title: Setting circuit for automatic channel selection stopping level of fm receiver
Inventor: YAMAZAKI MASAHIRO
IPC: H03J7/18
Filed: 1983-06-29
Abstract: PURPOSE:To set both the automatic stop level and automatic stereo level at optimum values respectively by setting both levels at different values. CONSTITUTION:A muting signal 7 delivered from a microcomputer for synthesizer is supplied to the base of a switching transistor TR5 in an automatic channel selection mode. Thus the TR5 is turned on by the signal impression. In this case, a variable resistor 4 and a resistor 6 are set in parallel to a terminal 2 of an IC for FMIF amplifier, and the synthetic resistance of both resistors is reduced. Therefore the automatic stop level is set at a high level, that is, the sensitivity is lowered. In a level setting mode the automatic stereo level is set at the optimum value by the resistor 4. Then the automatic stop level is set at the optimum value by the resistor 6.

Title: Chuck pressure controller
Inventor: HORIUCHI HITOSHI
IPC: B23B31/30
Filed: 1991-05-21
Abstract: PURPOSE:To perform compensation change of chuck pressure due to rotation accurately. CONSTITUTION:Pressure sensors 4, 4' detect output pressure of a proportional control valve 3. A compensation circuit 6 outputs a control signal which controls the operation of the proportional control valve 3 by feedback based on a difference between pressure set by pressure command signal from a pressure set circuit 5 which is operated by a subtractor 10 and output pressure which is detected by the pressure sensors 4, 4'. An adder 23 superimposes a dither signal of standard dither frequency from a first dither signal generation circuit l6 which is changed over and selected by a dither frequency change-over switch 19 or a dither signal of low dither frequency from a second dither signal generation circuit 17 on a control signal from the compensation circuit 6. Thus, input pressure-chuck pressure characteristics of chuck are improved by giving dither of low dither frequency to output pressure of the proportional control valve 3, and compensation of change of chuck pressure due to rotation is done accurately.
