Title: Organic metal vapor-growth device
Inventor: MURAKAMI TAKASHI
IPC: H01L21/205
Filed: 1988-10-03
Abstract: PURPOSE:To obtain the title device having no trouble with the roll mechanism of its susceptor without accumulation of a reaction product on a magnetic sealing part even when it is used for a long period by a method wherein an introduction hole of one of hydrogen gas, nitrogen gas and algon gas is provided at a part in the vicinity of a magnetic seal unit in the rotary shaft supporting part of a susceptor supporting rod. CONSTITUTION:An introduction hole 13 of one of hydrogen gas, nitrogen gas and algon gas is provided in the vicinity of the magnetic seal unit 6 of the rotary shaft supporting part of a susceptor supporting rod 9. For example, a hydrogen gas introducing hole 13 is provided in the vicinity of the magnetic seal unit 6, and hydrogen gas is introduced therefrom. As a result, an ascending air stream is generated at a bellows part 5, hydrogen gas is jetted out at all times from the gap located between an arsenic-dust protector 4 and the susceptor supporting rod 9, and the hydrogen gas is exhausted from an air exhaust hole. As a reaction product, which becomes the cause of trouble, is light in weight because it is fine grain of carbon and arsenic, the reaction product is washed away by the hydrogen gas jetted out from the gap and exhausted from the air exhaust hole 3. Accordingly, the reaction product passes through the gap between the arsenic-dust protector 4 and the susceptor supporting rod 9, and the reaction product is not accumulated on the magnetic seal unit part 6.

Title: Ceramic discharge lamp
Inventor: OKAMURA KAZUYOSHI
IPC: H01J61/34
Filed: 1989-09-28
Abstract: PURPOSE:To promote evaporation of a light emitting metal condensing in the coldest part and enhance the color rendering property by winding a current feeder on an electricity lead-in member in a plurality of turns, joining them together, allowing the current feeder to generate Joule's heat, and conducting the heat to the coldest part of the light emitting tube through the electricity lead-in member. CONSTITUTION:As holders 10, 10 for light emitting tube are joined with exhaust pipes 5, 5 as electricity lead-in member, the voltage introduced from a lamp base 2 is impressed on electrodes 6, 6 through the exhaust pipes 5, 5. That is, the lamp current flows during the lamp in lighting to the electrodes 6, 6 from the holders 10, 10 as current feeder via the exhaust pipes 5, 5, which thus generates a Joule's heat. This Joule's heat is connected to the exhaust pipe 5. Because this heightens the temp. of exhaust pipe 5, the coldest part is supplied with heat and its temp. rises to promote evaporation of the light emitting metal condensing in this coldest part. The color rendering property is thus enhanced.

Abstract: PURPOSE:To attain the setting coincident with acoustic environment of its own room without being affected from an opposite conference room by interrupting a call from the opposite conference room at the training of an acoustic echo canceller, inserting a white noise signal to a reception line and also interrupting a transmission line. CONSTITUTION:The training of an acoustic echo cancel(EC) is implemented such that a white noise signal(WN) outputted from a test signal generating circuit 8 is received by a reception amplifier 9 via the EC 3 by a test signal inserting circuit 7 and the WN loud-spoken by a speaker 10 is collected by a microphone 1 via an acoustic path of a conference room. A bypass signal of the collected WN is amplified by a transmission amplifier 2 and the amplified signal is inputted to the EC 3, and since the WN selected by the circuit 7 is connected to the input of the EC 3, the EC 3 generates a pseudo echo signal and reaches the converging state. Thus, the EC 3 is trained in the optimum state to the acoustic environment of the conference room, the conference start is prepared, and as soon as the circuit 7 selects the circuit 8, a training signal transmission stop circuit 4 is active and the transmission of an output of a training signal to the transmission line is interrupted.
