IPC: F02B25/04
Filed: 1982-09-14
Abstract: PURPOSE:To improve the efficiency of engine, by providing second scavenging ports on the side of a stage preceding the original scavenging ports, and automatically supplying a feed air, increased in temperature resulting from pressurization effected by a supercharger, from the scavenging ports in a manner that the air passes therethrough without any purpose but scavenging. CONSTITUTION:Second scavenging ports 9 are peripherally provided on the cylinder head side, and are communicated with the upstream side of an intercooler 7 through a second feed air pipe 10 and a check valve 11. While the upper end of a piston 3 is passing through the openings of the scavenging ports 9, hot feed air is supplied as scavenging air in a cylinder 1 through the check valve 11. Further, when the piston 3 reaches the bottom dead point, scavenging ports 2 are opened, and thereby pressure of cold feed air blown up in a pressurizing chamber 8 is high. As a result, the supply of the hot feed air from the scavenging ports 9 is stopped by the check valve 11, only cold air is supplied until the scavenging ports 2 are closed, and an engine is shifted in its compression stroke. Thus, hot feed air, remaining in the condition to be pressurized by a supercharger 5, is mainly utilized as a passing-through air for scavenging, resulting in improvement of the efficiency of engine.

Abstract: PURPOSE:To measure the distance between a nozzle and a work right under the nozzle with good accuracy by constituting the nozzle of a heat-resistant non-metallic material, coating a thin metallic film on the inside surface thereof and providing an eddy current type displacement sensor which detects the distance between the nozzle and the work to the top end thereof. CONSTITUTION:The nozzle 19 is formed of the heat-resistant non-metallic material such as ceramics and is highly resistant to heat. The thin metallic film 21 is coated on the inside surface of such nozzle 19 to reflect a laser beam LB and to prevent the nozzle 19 from injury. A coil 25 as the eddy current type displacement sensor is provided in proximity to the top end of the nozzle 19. The metallic film 21 coated on the inside surface of the nozzle 19 is extremely thin and is apart from the sensor 25; therefore, the greater part of the eddy current flows to the work W side when the sensor 25 is energized by a high frequency. The eddy current flowing in the film 21 is small and is negligible. Thus the sensor 25 can measure the distance L between the nozzle 19 and the work W right under the nozzle with the high accuracy.

Title: Protective device for thyristor bulb
Inventor: KANOU TAKASHI
IPC: H03K17/725
Filed: 1979-12-12
Abstract: PURPOSE: To prevent an element from breaking down by protecting a converter by detecting all forward overvoltage protecting circuits in a tray module entering into continuous operation.  
     CONSTITUTION: To each thyristor element 2, a series circuit of nonlinear resistor 14 and diode 15 is connected in parallel and light emission diode 16 is also connected in the opposite direction to diode 15. The voltage at which nonlinear resistor 14 starts to turn on is set a little bit lower than the operation level of forward overvoltage protecting circuit 12 and much higher than a voltage applied to the thyristor in normal operation. Consequently, when forward overvoltage protecting circuit 12 operates, light emission diode 16 can be turned on with current flowing through nonlinear resistor 14 to send a light signal. Since all light emission diodes emit light when all circuits 12 are in operation, protecting against the stop of a converter is provided by detecting the light emission.
