Title: Production of thin film transistor array
Inventor: TSUTSU HIROSHI
IPC: H01L29/78
Filed: 1987-05-15
Abstract: PURPOSE:To bore apertures without forming eaves parts and to obtain a thin film transistor array at a high yield by forming a resist mask on a 1st metallic layer, insulating layer and Si layer laminated on an insulating substrate and executing wet etching and reactive ion etching successively. CONSTITUTION:ITO layers 1 are selectively provided on a glass plate 7 and Cr layers 2 (scanning lines in common use as gate electrodes) are formed via SiO2 8. Si3N4 9 and i type amorphous Si3A are then laminated thereon and Si3N4 protective layers 10 are selectively provided. The resist mask 11 is formed and the side face etching is executed to bore apertures in the amorphous Si3A by a soln. of HF:HNO3=1:30. The resist in the side face etched part is brought into tight adhesion to the substrate by executing calcination. Apertures are then bored to the Si3N4 9 and the SiO2 8 by an RIE device of a parallel flat plate type using CF4+O2. Since the Si3N4 9 is etched earlier, no eaves are generated and the Si3N4 intrudes inner than the end margins of the resist. The resist 11 is removed and drain electrodes 6 are connected to the ITO 1 through Al layers 5 of the sources in common use as video signal lines and opened windows 4. Finally, the unnecessary layer 3A is removed with the Al layers 5, 6 and the protective layer 10 as a mask. The transistor array is thus completed.

Title: Optical submarine repeater
Inventor: YATSUDA MUNEAKI
IPC: H04B10/07
Filed: 1991-03-19
Abstract: PURPOSE:To improve the accuracy of location of a fault point by providing a changeover means connecting a measurement means to a pressure-proof case upon the occurrence, of a cable fault and a changeover means used to send voltage information from the measurement means to a relay means to the title repeater. CONSTITUTION:Normally a 2nd changeover circuit 5 is kept open and short- circuits a pressure-proof case 6 and a voltage counter circuit 4 based on a control signal superimposed on a main signal from a cable land station on the occurrence of a fault. The circuit 4 counts a voltage between the pressure- proof case 6 and a feeder of an optical submarine repeater and outputs the result to a 1st changeover circuit 3 as an information signal. The circuit 3 based on the control signal connects selectively its output to a modulation circuit input of a forward recovery repeater 1 or a modulation circuit of a return path recovery repeater 2. The modulation circuit of the repeater 1 or 2 superimposes voltage information counted by the voltage counter circuit 4 onto the main signal and transfers the result to a cable land station. Thus, the voltage between the cable having a fault and ground via the pressure-proof case and sea water is measured.

Title: Waveform regulating circuit
Inventor: FUCHINABE YUKIO
IPC: G01D5/36
Filed: 1980-08-31
Abstract: PURPOSE:To facilitate the regulation of the output of a sensor with a simple means by a method wherein the reference voltage of a comparator is switched between two levels and delaying and maintaining the state of the output. CONSTITUTION:The output V1 of a sensor and a reference voltage Vcc are applied to the (-) input terminal and the (+) input terminals, respectively, of a comparator 7. When the output voltage Vc of the comparator 7 exceeds a first reference voltage VPH with the increase of the output V1, the comparator 7 is switched on to generate an output pulse V2. Consequently, the output terminal of the comparator 7 becomes fanout free, namely, earth potential, so that an LED8 is lighted and the reference voltage is changed to a second reference voltage VPL. The voltage Vc will not change until the output V1 drops to the voltage VPL. When the output voltage V1 becomes smaller than the voltage VPL and the comparator 7 is switched off, the output terminal of the comparator 7 becomes high impedance. Consequently, the LED8 is switched off until the output V1 reach the voltage VPH. Thus the lighting period of the LED8 is extended to allow accurate level regulation.
