Title: Danger alarm for construction site
Inventor: OKINAGA HIROMITSU
IPC: B60R21/00
Filed: 1989-03-29
Abstract: PURPOSE:To prevent the contact accident on a construction site and to improve safety by receiving the radio wave from a radio wave transmitter and the ultrasonic wave from another ultrasonic wave transmitter/receiver and emitting an alarm when the time overlap of the radio wave and the ultrasonic wave arises. CONSTITUTION:The radio wave from the radio wave transmitter 10 is received in the ultrasonic wave receiving circuit 34 of the ultrasonic wave transmitter/ receivers 12a to 12e when this wave is transmitted. The ultrasonic wave transmitting circuit 36 transmits ultrasonic wave pulses upon lapse of the specified time after receiving the radio wave. The ultrasonic wave is delayed in time and is attenuated in amplitude according to distances and is received in another ultrasonic wave receiving circuit 38. An alarm signal output circuit 39 outputs an alarm signal to operate a buzzer and an alarm lamp when there is the time overlap in the radio wave reception signal from the circuit 34 and the ultrasonic wave reception signal from the circuit 38. The contact accident is prevented and the safety is improved by mounting such ultrasonic wave transmitter/ receivers to construction machinery or the object to be touched.

IPC: H01L21/316
Filed: 1985-04-11
Abstract: PURPOSE:To contrive the simplification of the fabrication process of a silicon oxide film by using the mixed gas of an organic silicon compound gas and an oxygen gas. CONSTITUTION:After reducing the pressure in a reactor 5 to 10<-6>Torr, the mixed gas of an organic silicon compound gas and an oxygen gas are introduced into the reactor 5 from a flow control system 3. After introducing the mixed gas, a high-frequency power is supplied to an RF coil 6 to generate a plasma in the reactor. When a plasma is generated, the mixed gas is decomposed to deposit a silicon oxide film on a substrate 9. After depositing the silicon oxide film, the supply of the mixed gas and the high-frequency power stops. Subsequently, nitrogen gas is introduced into the reactor to remove residual radicals and the pressure in the reactor is restored to the atmospheric pressure. Then the substrate 9 is taken out. By mixing the oxygen gas, the contents of oxygen and hydrogen in the formed film are almost zero so that the high-temperature treatment is not necessary.

Abstract: PURPOSE:To prevent the spread of short-circuiting and the generation of an explosion noise or a smoking phenomenon by filling an insulating resin for insulation among a wires in a case which houses windings and by providing a temperature detecting means which detects the heat conducted from windings to the insulating resin. CONSTITUTION:A flyback transformer is formed with a winding A (a primary winding 33, secondary windings 35a, 35b, 35c), a case 38 which houses the winding A and an insulating resin 37 filled in the case 38. In this case, temperature detecting means which can detect the heat conducted from the winding A at the periphery of the resin 37 are provided. The temperature detecting means consist of a detection line (conductor) 41 extended to the direction of the winding axis of the winding A and a thermocouple (temperature sensor) 40 which detects the temperature conducted to the conductor 41. During the operation, if the temperature in the case 38 is raised above a definite value, the sensor 40 is operated and the movement of a horizontal deflection circuit itself is stopped. This prevents the generation of an explosion noise or a smoking phenomenon.
