Title: Power supply plug engagement detector
Inventor: KUWABARA HIROAKI
IPC: G08B25/10
Filed: 1990-02-21
Abstract: PURPOSE:To detect the states of plural power supply plugs only by one master machine by allowing an LCX resonance circuit to generate a response signal to a monitoring frequency signal outputted from the master machine when a plug is inserted to a plug socket. CONSTITUTION:Although the resonance current of an LC parallel resonance circuit is quickly attenuated, that of the ALCX parallel resonance circuit is moderately attenuated as compared with the LC type circuit because of the existence of a crystal oscillator 20 and time T0 to be attenuated to a receivable critical level is extended. Since the Q level of the LCX type circuit is high, its resonance waveform is made sharp and a frequency band required for identifying the received response signal can be narrowed, so that plural response signals in different frequency bands can easily identified without generating mixing. Thereby, the intervals of loop antennas 13 corresponding to plug sockets to which power supply plugs 31 to 3n are to be inserted can be expanded and the frequency bands of plural kinds of response signals in a narrow band can easily be identified, so that plural sensor parts can be managed only by one master machine.

Title: Delayed light emission device for electronic flash
Inventor: INOUE HIDEKI
IPC: H05B41/34
Filed: 1986-02-26
Abstract: PURPOSE:To view the state of an invariably constant operation point by obtaining a trigger output pulse when high-frequency pulses are counted by an output counted value from the input point of time of a trigger input pulse. CONSTITUTION:Clock pulses P0 which are oscillated 3 are inputted to an up counter 5 and a presettable down counter 6. Then, the trigger input pulse P1 applied to a trigger input terminal 2 is inputted to an arithmetic control circuit 4, which in case of reading the pulse P1, reads in the number of pulses P0 counted by a counter 5 up to the currently read pulse P1 from the last pulse P1, i.e. counted value N and clears the counter 5. The circuit 4 calculates a proportion constant alpha/2pi=K from a single from an input terminal 1 which corresponds to an operation angle alpha and a signal from one period 2pi of a shuttle and also calculates an output counted value N.K=I from the constant K and counted value N. The counter 6 loads the counted value I at the input point of the pulse P1 to a terminal 2, starts counting with the pulse P0, and obtains the trigger output pulse P2 at a trigger output terminal 8 when counting up to the counted value I.

Title: Method for correcting delay signal
Inventor: YASUDA HIDEYUKI
IPC: H04N9/77
Filed: 1985-02-28
Abstract: PURPOSE:To attain the stable and accurate correction of delay signal without necessity for the delay line of a coil-structure by A/D-converting the luminance signal separated from a composite video signal and by delaying the converted digital luminance signal by an amount corresponding to the delayed amount by means of a digital delay circuit. CONSTITUTION:The digital color difference components (R-Y)dd and (B-Y)dd are delayed to the digital luminance signal Yd by the amount occurred at the processing in a composite video signal processing circuit 2. The digital luminance signal Yd from the A/D converting circuit 3 is inputted to a digital delaying circuit 4, where the said signal Yd is processed to be delayed by the amount equal to that of the delay of the digital color difference components (R-Y)dd and (B-Y)dd, and is outputted. Consequently, the digital luminance signal outputted from the circuit 4 coincides with the signal (R-Y)dd and (B-Y)dd in timing to form the delay-corrected signal.

Title: Treatment of donor killer of silicon wafer
Inventor: MASUI TSUMORU
IPC: H01L21/322
Filed: 1989-02-21
Abstract: PURPOSE:To prevent a decrease of a lifetime of a single-crystal silicon wafer by a method wherein the wafer is heat-treated under a specific condition in an oxygen atmosphere. CONSTITUTION:A donor killer of a single-crystal silicon wafer is heat-treated under conditions at a temperature of 600 to 900 deg.C and for 240 to 10 minutes in an oxygen atmosphere. That is to say, instead of nitrogen or an inert gas which have been used in conventional methods, the oxygen atmosphere is adopted as an atmosphere during a heat treatment of the wafer. Accordingly, when the wafer is heat-treated in the oxygen atmosphere, a comparatively thin silicon oxide film is formed on the surface of the wafer; this film yields a barrier effect to prevent that heavy metal impurities existing on the surface of the wafer, on a jig coming into contact with the wafer or in an atmosphere are diffused to the inside of the wafer. Thereby, it is possible to prevent a decrease of a lifetime of the wafer which may be caused by a contamination of a heavy metal when the wafer is heat-treated by a conventional methods.
