Title: Manufacture of light receipt element of thin film type
Inventor: TAKENOUCHI MUTSUO
IPC: H01L31/0264
Filed: 1980-03-14
Abstract: PURPOSE:To improve a light and dark current ratio by a method wherein the light- dark current ratio of the light receipt element is changed by an oxygen partial pressure of a spattering atmosphere appearing when a light transmissive electrode is spattered, and the oxygen partial pressure value is set near a point where a peak value of the light-dark current ratio is obtained. CONSTITUTION:A band-shape electrode 2 is layer-built to a prescribed thickness on a grounding chrome of a flattened substrate 1 of a quartz glass or the like which is optically polished on the surface, and additionally a photoconductive thin film 3 is formed on the electrode 2 to a prescribed thickness. The light transmissive electrode 4 made of tin oxide is formed on the thin film 3 by a magnetron-type spattering. When the light transmissive electrode 4 is spattered, the oxygen is induced after the attained pressure in a vacuum tank is suppressed under a prescribed value, the oxygen pressure being stabilized at a prescribed pressure, and argon as a spattering gas being induced to effect setting the value of the oxygen partial pressure near the peak value of the light-dark current ratio. Thus, the light transmissive electrode 4 is adapted to have transmissivity of more than 75% and to be 500 in the light-dark rate as the light receipt element and more than 10 PA/LUX in photosensitivity.

Title: Time processor
Inventor: MIZUGUCHI MASAAKI
IPC: G05B19/02
Filed: 1981-03-05
Abstract: PURPOSE:To set sequence control accurately and easily, by setting a diode pin to a crossing of wiring of a matrix shape. CONSTITUTION:Step lines Sl corresponding to the number of steps of sequence control and time setting lines 28S to a jump setting section 30  are provided in a crossing shape. When a step counter designates a step line Sl1, the time set on the step line Sl1 is set to a subtraction counter. The subtraction counter outputs a signal when the result of subtraction reaches zero from the set value. The step counter is advanced by one with this signal. As a result, the next step line Sl2 is designated and the next time is set to the subtraction counter. When the section 30 is set, the step counter stops sequential operation and jumps to a count value ''1'', consequently, the control can be transited to the required operation.

Title: Automatic program searching device of video tape
Inventor: YOSHINAGA KAZUNORI
IPC: G11B27/28
Filed: 1983-02-28
Abstract: PURPOSE:To attain the automatic program searching at a desired position in a simple and assured way without performing previously a complicated operation, by comparing a reproduction mark signal with a reference signal to control the stop of reproduction. CONSTITUTION:A color bar of a video tape is reproduced into a reproduction mark signal and compared with a reference signal by a differential amplifier 1. The output of a waveform shaping circuit 3 is set at a low level with the coincidence between the inputs of both signals. At the same time, the output of a gate 5 is kept at a low level. As a result, a gate 7 is closed and the set output of a timer 6 is cut off. Then the reproduction of the tape is continued, and the output of the amplifier 1 is inverted to a high level by the reproduction output of a credit part. Then the gate 7 is opened with a vertical synchronizing signal supplied from the credit part via a gate 5 and a sampling pulse generator 4. Thus the set output of the timer 6 is delivered as a reproduction stop signal, and at the same time the timer 6 is reset to perform the program searching. In such a constitution, the program searching is automatically performed without having any pre-operation such as recording of a time code, etc.

Abstract: PURPOSE:To generate a call tone from plural radio terminal equipments in a short time simultaneously by allowing a representative radio terminal equipment only designated by a master equipment to return a communication channel switching end signal to the master equipment at a call coming from a wired line and allowing the master equipment to send a bell ring signal in response thereto. CONSTITUTION:When a call comes to a wired telephone line 3, the master equipment 1 checks the idle state of a control channel and sends a signal including only the ID code in the incoming signal when the channel is idle. When radio telephone sets 2, 2' receive an incoming signal including the ID code coincide with the ID code assigned to itself, they return an incoming reply signal in the timing specified by the ID code. Upon the receipt of the incoming reply signal, after a communication channel designation signal is sent, the equipment itself is switched to the designated communication channel. In the reception of a channel switching end signal from the radio telephone set 1 being a representative radio telephone set, a bell ring signal is sent and a call tone is generated simultaneously from the two sets of the radio telephone sets 2, 2'.
