Title: Reaction tube of vapor growth device
Inventor: KAMEI HIDENORI
IPC: H01L21/205
Filed: 1986-01-23
Abstract: PURPOSE:To suppress contamination within a reaction tube by inserting a reaction gas supply tube from the one end of reaction tube up to the part near to the susceptor, providing a purge gas supply port to the outer end and coupling a gas exhaust port to the space between the reaction gas supply tube and internal wall of said reaction tube. CONSTITUTION:When the reaction gas is supplied from a reaction gas supply tube 8 into a reaction tube 1, simultaneously the purge gas is supplied from a purge gas supply port 9 and the gas is exhausted from a gas exhaust port 11, the non-decomposed reaction gas not used for formation of thin film passes on the substrate 7 and flows upward in the space 10 with the purge gas, passes the gas exhaust port 11 and is exhausted to the outside of reaction tube 1. Thereby, the non-decomposed reaction gas not used for formation of a thin film does not pass the periphery of susceptor heated in the course of exhaustion. Accordingly, non-volatile product generated by thermal decomposition of non-decomposed reaction gas included in the exhaust gas is adhered to the internal wall of reaction tube ranged from the region near the susceptor to the down-stream, thereby preventing contamination of internal wall of the reaction tube. The single-sided flow of purge gas and exhaust gas in the reaction tube 1 can be prevented by providing the purge gas supply port 9 and gas exhaust port 11 with an equal interval.

Title: Method for sterilizing container
Inventor: HIRAYAMA TAKAHISA
IPC: B65B55/10
Filed: 1988-01-25
Abstract: PURPOSE:To eliminate non-uniformity of germicide application and heating and efficiently sterilize a container by a method wherein after germicide is sprayed, steam is sprayed and heated with hot air to allow the germicide to be decomposed and vaporized. CONSTITUTION:After inner walls of a liquid container, before filling with content, made of paper forming a bottom face and a body and having an opening on the upper face are sprayed with a 35% water solution of H2O2 then sprayed with steam to be wetted and heated, the inner walls are heated with hot air twice to permit H2O2 to be vaporized and removed. Since germicide after being applied is heated and wetted simultaneously with steam, latent heat is high and heating takes place in short time, but partial heating can be prevented. In addition, the germicide is not vaporized immediately after application and the inner walls of the container are well wetted so that the germicide can be uniformly spread on a plying-up portion.

Title: Production of silver/palladium powder
Inventor: NAKANO KIYOSHI
IPC: B22F9/24
Filed: 1994-02-08
Abstract: PURPOSE:To produce a silver/palladium powder for a conductive paste eliminating an occurrence of a delamination (ply separation) even if the paste is heated at the time of baking the paste by adding formalin to a soln. of glycols in which silver nitrate and palladium nitrate are dissolved and subjecting this mixed soln. to a reducing treatment by heating to produce the silver/palladium powder. CONSTITUTION:The silver nitride and the palladium nitrate corresponding to an required silver/palladium wt. ratio is prepared, and these are added and dissolved to a soln. such as ethylene glycol and propylene glycol. Then formalin is added to this soln. and agitated sufficiently to make a mixed soln.. Next, this mixed soln. is subjected to reducing treatment by heating, that is, when the soln. in heated and reduced at 120-170 deg.C for about 1 hour the silver/ palladium powder boils azeotropicaly, and the powder is recovered, washed and dried. Since this silver/palladium powder does not cause an oxidative expanding phenomenon even if it is heated at the baking temp. of the paste, interlayer separation is prevented.

Title: Accumulator device
Inventor: NARUSE OSAMU
IPC: B41J2/195
Filed: 1980-02-08
Abstract: PURPOSE:To make pulses uniform and smooth by a method wherein a piston in an accumulator is driven and controlled so that a volume within the accumulator may increases and decrease in accordance with the magnitude of an ink pressure and an output ink pressure rise characteristics against an ink pressure from a pump is improved. CONSTITUTION:A piston 3 is rotated through a belt 5 by means of a pulse motor 4 to be moved upward and downward in a guide screw system. An ink pressure of ink fed into an accumulator 1 by means of an ink pressing pump 12 is detected through a pressure detecting sensor 7. When the ink pressure is less than a normal vaue, the piston 3 is made to descend so as to raise the ink pressure within the accumulator 1 without delaying the rising of the ink pressure fed in from the pump 12. The pulse of the ink pressure is detected through the sensor 7 and the output therefrom is sent to a detection circuit 9 and the signal sent from the circuit 9 enters a driving circuit 11 via a control circuit 10 and the output signal from the driving circuit 11 raises the piston 3 in a time band wherein pressure is too large and it lowers the piston 3 in a time band wherein pressure is too small.

Title: Ground fault detector
Inventor: SATO EIICHI
IPC: H02H3/347
Filed: 1990-01-23
Abstract: PURPOSE:To prevent unnecessary operation caused by intermittent switching surge and noises by checking, with a discrimination signal received by a gate circuit, output from a waveform shaping circuit after the time range of the pulse of a gate control signal transmitted from a one-shot circuit. CONSTITUTION:The first output is entered to a signal width discrimination circuit 5 through a gate circuit 4. When the discrimination signal of the signal width discrimination circuit 5 exceeds the discrimination value, a one-shot circuit 6 and a pulse generation circuit 7 transmit a pulse of the specified time range and a count pulse respectively. Because the gate circuit 4 is closed by the pulse for the specified time period, the following output from a waveform shaping circuit 3 cannot pass through the gate circuit 4 and is eliminated. Therefore, only one count pulse is integrated by an integration counter 8, the potential of a capacitor 8a in the integration counter 8 does not reach the discrimination value, and a switching element 10 is not triggered.

Moreover, when the caller and the registered person are dissident, the remote control message controller 13 has a function of receiving and recording a message from the caller. Thus, only a specific person can access the telephone set provided with the remote control message controller 13 from the outside device such as a public telephone set and the telephone set is used to start the remote control message controller of the person to which the own message is desired to be delivered.
