Title: Method for manufacturing semiconductor device
Inventor: MATSUMURA TAKAO
IPC: H01L29/47
Filed: 1992-06-18
Abstract: PURPOSE:To provide a GaAs MESFET for excellent microwave band without fluctuating the drain current during the measuring step of DC and high-frequency at all by a method wherein a heat-resistant Schottky metal deposited on the surface of a compound semiconductor substrate exposed in an aperture part formed on an insulating film is to be heat-treated at the temperature within specific range. CONSTITUTION:An insulating film 2 deposited on one main surface of a compound semiconductor substrate 1 is etched away by RIE step so as to form an aperture part on a prospective Schottky gate region. Next, a heat-resistant Schottky metal 4 deposited on the surface of the compound semiconductor substrate 1 exposed in the aperture part is heat-treated at 500-600 deg.C. For example, a silicon oxide film 2 deposited on the GaAs substrate 1 is etched away by RIE step and then heat-treated in Ar atmosphere at 400-500 deg.C to recover the RIE damage. Next, the Schottky metal 4 comprising WSi is deposited and after the heat treatment in Ar atmosphere at 500-600 deg.C, Ti-Au is deposited and etched away to form a gate electrode 5.

Title: Tower type furnace for executing heat treatment to metallic strip material
Inventor: EBNER PETER
IPC: C21D9/00
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To achieve a desired temp. of a strip material without delaying heating of the strip material caused by excessiveness of broken length of a muffle and low temp. part in a furnace, by providing an electric heater, inserting an insulated plug body into the upper position of the muffle and positioning a preheating chamber at the lower position of the plug body. SOLUTION: The insulated plug body 1 having the electric heater 2 is inserted into the upper end part of the muffle 3 extended to the whole length of the furnace. The preheating chamber 4 is positioned at the lower side of the plug body 1, and thereat, the muffle 3 is heated with gas from the outside through a gap 4a. In the furnace having such a constitution, the strip material 6 for executing heat treatment, is carried. Since the vol. of the plug body 1 is far smaller than a furnace without muffle 3, even after interrupting the operation for comparatively long time, a bright annealing application can be obtd. within a short time. Further, since the temp. of the outer wall of the muffle 3 is lowered only a little in the plug body range, the strengths of materials are risen and such danger as to generate an excessive broken length of the muffle 3 does not happen.

Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To provide an environmental equipment for biology experiments which enables the cleanliness of clean space to reliably be maintained and safely be realized at a low cost. SOLUTION: A transparent titanium oxide membrane is formed on the surface of a metallic plate 6 and a shutter 5 made of transparent glass which are partition walls surrounding/forming clean working space S of a clean bench 1. When the clean bench 1 is unused, the titanium oxide membrane is activated under exposure to ultraviolet rays from a germicidal lamp 11 and miscellaneous germs, etc., adhered to the titanium oxide membrane are reliably sterilized by photocatalytic reaction. Since all surfaces of partition walls for the clean working space S are covered with the titanium oxide membrane and are photocatalytically activated e.g. with a germicidal lamp 11, a clean working space S having a high sterilizing characteristics can be realized.

Title: Printer
Inventor: MIYAZONO YUTAKA
IPC: B41J29/377
Filed: 1990-06-19
Abstract: PURPOSE:To make air in a case circulate by movement of a carriage and to cool a printing head therewith by a method wherein a plate member is installed to the carriage that moves the printing head mounted thereon so that the direction in which the carriage travels is intersected by the plate member. CONSTITUTION:Printing is made with a printing head 1 that is driven with a carriage 5 that travels in reciprocation in an air channel. A piston member 31 is made of a flat plate in a shape approximately the same as the sectional shape of the air channel, and travels in reciprocation together with the carriage 5 as it is fixed to the carriage 5 with screws that are inserted through fixing holes 31c. When the carriage 5 travels in one direction, hot air in the air channel is exhausted by effect of the piston member 31 toward the direction of the travel and, at the same time, air on the outside of a case of a printing device is sucked into the air channel from the side opposite to the direction of the travel.. When the carriage 5 travels in the opposite direction, the exhaust and the suction are made likewise. Ventilation in the air channel is made as mentioned above by reciprocating travels of the carriage 5, and thereby the printing head 1 can be cooled down.

Photoresist is applied to the front face of the resin tape, which is then subjected to mask exposure. The liquefied rear protective agent is applied to the rear face of the tape and dried. The copper foil is etched on the photoresist side to form a wiring pattern. Then the photoresist film on the front face of the resin tape and the rear protective agent film on the rear face are simultaneously removed.
