Title: Manufacture of insulated gate semiconductor device
Inventor: FUNAKOSHI AKIHIKO
IPC: H01L21/266
Filed: 1993-02-25
Abstract: PURPOSE:To provide a method for manufacturing an insulated-gate type semiconductor device whereby the processing time of its ion implantation can be made short largely, by using a thick oxide film as a mask instead of a resist. CONSTITUTION:A thick oxide film 14 is formed concurrently with the formation of a P<+> region 13. In the process wherein the surface of an element forming part is exposed to the outside, the partly thick oxide film 14 is left on the P<+> region 13. Then, a gate oxide film 15, a gate electrode 16 and a P-type channel region 17 are formed in succession, and by the ion implantation wherein the gate electrode 16 and the left thick oxide film 14 are used as masks, an N<+> source region 18 is formed.

Title: Frozen mold
Inventor: OOHASHI YOSHINOBU
IPC: B22C9/02
Filed: 1980-03-19
Abstract: PURPOSE:To considerably prolong the time when a frozen mold can be left standing by penetrating a binder from the mold molding surface thereby forming a hardened shell layer. CONSTITUTION:After molding or after freezing, a binder is coated on at least the molding surface 2 of a mold 1, by spraying, brushing or immersing therein to allow this to penetrate among the sand grains of the mold 1 from the surface, whereby a hardended shell layer 3 is formed. The binder is ordinary water glass, and is rapidly hardened by bringing the water glass into to contact with a gasous CO2. When the mold formed with the hardened layer 3 in this way is left standing in the atmosphere after freezing, the hardened layer 3 plays the role of a heat insulating layer covering the mold 1 and performs the action of retarding the temp. rise of the entire part of the mold 1 from the surface, thereby maintaining the surface stability of the molding surface 2.

Abstract: PURPOSE:To exclude the air perfectly from the inner part of the member to be adhered and the adhesion clearance, by providing an airtight chamber which encloses the member to be adhered and a heating plate and can open and close at will and fusion-bonding them by heat after reducing the pressure in the chamber. CONSTITUTION:After an adapter plate 2 attached beforehand with a member 5 is set at the predetermined position under a heating plate 3 and a tank 4 is made to descend and contact its lower opening to the adapter plate 2, the inside of an airtight chamber 41 containing the member 5 is evacuated by operating a pressure reducing mechanism 43 and the clearance between inner and outer vessels 51, 54 and the clearance between the flanges 52, 55 of the member 5 are made vacuum. Then, the opposing adhering parts of the member 5 are pressed and fusion-bonded by lowering the heating plate 3. Thus, air is perfectly excluded from the inner part and the adhesion clearance of the member to be adhered by providing the airtight chamber 41 which encloses the member to be adhered and the heating plate 3 and can open and close at will and fusion-bonding by heating after reducing the pressure in the chamber.

Title: Method for detecting failure in temperature sensor and temperature defection device
Inventor: KIKUCHI YOSHITERU
IPC: G01K7/24
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To positively detect the occurrence of disconnection by positively discriminating the disconnection from a normal operation. SOLUTION: A voltage detection part 24 converts the resistance of a temperature switch RT to a voltage value. A history storage part 28 stores a voltage increase history until a voltage value increases, crosses a specific rise zone, and enters a disconnection above a disconnection threshold voltage. A disconnection judgment part 30 discriminates disconnection from switch operation based on the voltage rise history. When a voltage value crosses the rise zone instantly so that it jumps the rise zone, it is judged that disconnection occurred, namely the voltage value of the disconnection zone has been abruptly detected without allowing the voltage value of the rise zone to be detected. On the other hand, when a voltage value crosses the rise zone while spending a certain amount of time, it is judged that the switch operated normally.

IPC: H04B1/04
Filed: 1992-02-25
Abstract: PURPOSE:To prevent interference from being given onto an adjacent line even when a fault takes place in a transmission output control circuit of a transmitter at a sender side. CONSTITUTION:A transmitter 11 at a sender side controls a transmission output in response to reception level information Lr sent from a receiver side. An output detector 14 detects a transmission output level of the transmitter 11. A comparator 15 compares transmission output level information Lt with the reception level information Lr to detect an error in a transmission output and to send an error signal At, which is sent to the receiver side via a multiplexer circuit 16 and the transmitter 11. A receiver 22 at the receiver side detects the error signal At and sends the signal to a changeover controller 24, which selects a line changeover device 61 to the position of a standby line and sends a switching signal Cs to the sender side via a multiplexer circuit 23 and a transmitter 21. A changeover control circuit 13 at the sender side receives the switching signal Cs from the receiver side to throw a line changeover device 51 to the position of the standby line thereby stopping the operation of the transmitter 11.
