Patent JP-H10309074-A (JP)
Title: Thyristor valve
Inventor: KOBAYASHI ATSUO
IPC: H02M1/00
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a thyristor even when a forward overvoltage is impressed upon the thyristor during a transient period, by injecting electric charges into the gate section of the thyristor regardless of the magnitude and increasing rate of the forward voltage applied across the thyristor during a prescribed period after a feed of a thyristor current is disconnected. SOLUTION: When a feed of a thyristor current IT is disconnected and a reverse voltage appears at a thyristor LTT, a reverse voltage signal RV is detected and inputted to a logic circuit LG2. The circuit LG2 elongates the signal RV and outputs a protecting period setting signal. The setting signal is amplified by means of an amplifier AMP2 and turns off a switching device S2 so as to make a current I2 flow to a light emitting diode LED. Since the current I2 is limited to a sufficiently small value as compared with another current I1 by means of a series impedance Z2, weak optical gate power is inputted to the thyristor LTT only during a transient period. Therefore, even when a forward overvoltage higher than the breakdown voltage of the thyristor LTT is impressed upon the thyristor LTT, the thyristor LTT is not broken, because the thyristor LTT is turned on from a gate section.

Title: Video/audio output device
Inventor: HAYASHI HIROYUKI
IPC: H04M3/56
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To enhance the presence by detecting the position of a talker in a video image so as to control a variable resistor thereby enabling a listener to hear a voice from the position of the talker even with a monaural voice input. SOLUTION: The position of a talker in video data is detected and the level of an input voice at the position is controlled and the resulting data are outputted to a plurality of speakers. That is, a video data input section 101 receives video data including the image of the photograph of the talker and gives the data to a video output section 105 and an area detection section 103. The area detection section 103 detects the position of the talker in the video image based on the video data and gives information denoting the position of the talker to a volume control section 104. The volume control section 104 controls a volume of the voice fed from a voice data input section 102 based on the position information of the talker in response to respective speakers 106 and provides an output of the result.  Thus, by controlling the volume control section 104 based on the detected position and outputting the voice whose volume is controlled to a plurality of the speakers, the position of the voice is changed.

Abstract: PURPOSE:To obtain a thermal spraying film having an excellent adhesion property even with a substrate having ruggedness of shot blasting, etc., by subjecting this substrate to a cleaning treatment by a negative shifting type arc while preheating the substrate within a reduced pressure plasma vessel. CONSTITUTION:The substrate is preheated by the negative shifting type arc under a pressure of <=15Torr and the preheating is stopped before the substrate attains 700 deg.C at the time of the cleaning treatment. The treatment is executed by the procedures of first installing the substrate 5 in a vacuum chamber 1 and evacuating the inside of this chamber, then introducing gaseous plasma into the chamber. The substrate 5 is then moved back and forth in front of a plasma gun 2 and is rotationally moved by using a substrate driving device 6 while a plasma frame is generated in a plasma thermal spraying gun 2 by a plasma generating source 3 and the shifting type arc is generated to the substrate 5 by a shifting type arc current 7. As a result, the entire surface of the substrate 5 is cleaned by the cathode point of the negative shifting type arc and, therefore, the substrate 5 is thereafter retreated and the generation of the shifting type arc is stopped. Henceforth, the thermal spraying is executed by the conventional method.
