Title: Voltage detection circuit, drive circuit and failure detection circuit for thyristor
Inventor: YAMATO IKUO
IPC: H02H7/12
Filed: 1994-12-14
Abstract: PURPOSE: To reduce the cost by decreasing the number of light emitting elements and optical fibers. CONSTITUTION: When forward voltages higher than the clamp voltages of Zener diodes 70, 71 is applied to thyristors 10, 11, a current depending on the clamp voltage flow into an LED 20 which produces light in proportion to the current. The light is transmitted on a signal optical fiber 30 to an optoelectronic converter (O/E) 40 which produces a voltage detection signal. A level decision circuit 80 compares the voltage detection signal with two kinds of decision level 1, 2. When only one thyristor is applied with a forward voltage, only a voltage presence signal 1 goes high but when two thyristors are applied with forward voltage, a voltage presence signal 2 goes high. Consequently, a failure detection circuit 61 can decide whether the thyristor 10 or 11 is faulty based on the voltage presence signals 1 and 2.

Filed: 1991-10-30
Abstract: PURPOSE:To select an arbitrary screen against as a counter measure for preventing the degradation of image quality, especially the deterioration of resolution due to the low bit rate transmission of dynamic images attending on the movement and to transmit the high quality image. CONSTITUTION:The image is transmitted through a frame memory 1 storing arbitrary one screen of the dynamic image to be inputted, a selector 2 selecting either one of the input of a memory or an output video signal, and an information source encoding part 100 using at least the correlation (between frames) in the time base direction. One screen is stored in the frame memory by a frame selection signal, and the same image is transmitted only for the time selecting the memory output in the selector. The correlation between frames becomes '1' equivalently in the encoding using the correlation between frames in the time base direction and the difference with the former frame can be gradually reduced to zero in the lapse of the time. Thus, the high resolution image can be obtained on a reception side even in the low bit rate transfer of the dynamic image with small correlation.

Filed: 1990-11-16
Abstract: PURPOSE:To improve efficiency for processing business by enlarging the applied range of image formation by controlling the selection of the output of synthesizing comment information to the front side or rear side of a recording paper sheet. CONSTITUTION:A copy operation command inputted from a manipulator 400 outputs various commands for operating other units at prescribed timing so that a copy processing as commanded can be executed by a system controller 302. Since it is controlled to synthesize the comment information on the both front and rear sides of the recording paper sheet, the comment information is synthesized on the both front and rear sides of the recording paper sheet by one original read processing although it is conventionally necessary to execute the copy synthesizing operation twice when trying to synthesize the comment information onto the rear side as well. Thus, since the applied range of image formation is enlarged by controlling the selection for synthesizing the comment information to the front side or rear side of the recording paper sheet, efficiency for processing business can be improved.
