Title: Liquid fuel combustor
Inventor: YOKOYAMA NOBUYOSHI
IPC: F23N5/02
Filed: 1978-11-11
Abstract: PURPOSE: To greatly reduce power consumption by maintaining the temperature of an evaporation portion of a burner within a proper temperature range using combustion air control means.  
     CONSTITUTION: When a temperature range (d) for setting a predetermined temperature A 2  is set higher than a temperature range (b) for turning on an electric heater 14, the temperature of an evaporation portion 111 is controlled to within a proper temperature range (a) by only increasing and decreasing the amount of combustion air. By this constitution, the temperature control for the evaporation portion 111 does not require assistance of the heater 14, so that the heater 14 functions only for warming up the portion 111 in the starting operation. As a result, power consumption is reduced considerably and the useful life of the heater 14 is prolonged.

Title: Control circuit for loud talking
Inventor: NONAMI TAKAYUKI
IPC: H04M1/60
Filed: 1985-06-26
Abstract: PURPOSE:To avoid interruption of head of speech by adding a delay circuit to the pre-stage of a talking sound volume changeover switch of a loud talking control circuit. CONSTITUTION:A transmission delay circuit 3 is arranged between a microphone amplifier 2 and a transmission sound volume changeover switch 4. In this case, a sound signal to a transmission sound volume detector 11 is extracted between the circuit 3 and the amplifier 2. The voice inputted to a microphone 1 is inputted to the circuit 3 via the amplifier 2, a prescribed value of delay is given and the result is inputted to the switch 4. Thus, since the transmission voice signal is inputted after the switch 4 is changed over sufficiently when the mode is changed over from the reception to the transmission, the interruption of head of speech is avoided.

Title: Photo-excitated dry etching and equipment therefor
Inventor: MOCHIZUKI YASUHIRO
IPC: H01L21/302
Filed: 1987-06-05
Abstract: PURPOSE:To enable the highly precise anisotropic etching only with photo- excitation etching reaction, by making etching gas adsorbed by a substrate and the substrate react with each other by light irradiation. CONSTITUTION:A substrate 1 on which a prescribed mask pattern is formed is set in a reaction vessel, the inside of which is exhausted. Then etching gas 3 is introduced into the reaction vessel, and absorbed by an aperture part of the mask 2 on the substrate 1. The etching gas 3 in vapor phase is exhausted and eliminated, the substrate 1 is vertically irradiated with light, to make the absorbed etching gas 3 and the substrate 1 react with each other, and volatile reaction product is exhausted and eliminated. By repeating the reaction process between the etching gas 3 and the substrate 1, the etching is processed up to a specified depth. In this process, the substrate 1 is vertically irradiated with light. As the result, the bottom part only is etched, and the sidewall is not subjected to etching. Thereby, the anisotropic etching is enabled.

Title: Intake device for engine with supercharger
Inventor: NISHIKAWA TOSHIO
IPC: F02B33/44
Filed: 1988-06-07
Abstract: PURPOSE:To suppress the generation of a stumble caused by over boost on rapid acceleration, by turning off an electromagnetic clutch so as to inhibit operation of a supercharger, when a throttle valve is not opened more than a prescribed opening in the medium/high load range of an engine. CONSTITUTION:In such a state as the opening of a throttle valve 13 detected by a valve opening detecting means 38 is less than a prescribed opening, when an engine 1 is operated in medium/high load range, an inhibiting means 39 keeps an electromagnetic clutch 15 in its OFF-condition so as to inhibit operation of a supercharger 10. Therefore, when the engine 1 is accelerated rapidly, even if the opening action of the throttle valve 13 is later than the ON-action of the electromagnetic clutch 15, intake air pressurized by the supercharger 10 is not confined into an intake passage 5. On the other hand, when the throttle valve 13 is closed by a control means 36 in an engine rotating range which is lower than the minimum rotating speed in the ON-operating range of the electromagnetic clutch 15. The throttle valve is not closed with the supercharger 10 in operating condition. Thus any rise of the operating temperature of the supercharger is avoided so as to improve the durability of the intake device, and a stumble caused by over boost can be prevented.
