Title: Recording device and heating device used therefor
Inventor: NAGATO KAZUSHI
IPC: G03G15/20
Filed: 1992-03-10
Abstract: PURPOSE:To reduce power consumption and shorten the warming-up time by pressing recorded material through pressure-conductive resin, and applying voltage to the pressure-conductive resin. CONSTITUTION:A heat insulating layer 5 is formed around a core roller 4, and a conductive layer 2, a pressure-conductive resin layer 1 and a conductive layer 3 are formed thereon to form a heating roller 6. Recording paper with a toner image formed thereon is conveyed when the heating roller 6 and a pressure roller 8 is being rotated in pressure contact, and a power supply 7 is connected during the passage of the recording paper so as to heat the heating roller 6, thus performing fixing. Since the volume resistivity of the pressure- conductive resin is reduced sharply in a great deal at the time of pressure being applied thereto, the most of a current is concentrated on the pressure contact part in the case of impressing the power supply 7, so that heating is generated at that part. That is, only the surface of the heating roller 6 and that only the part in pressure contact with the recording paper is heated. Power consumption in a recording device can be thereby reduced.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To decrease the resistance of a high melting point metal silicide film while preventing deterioration of surface profile by purging the gas in a chamber through introduction of an inert gas and returning a wafer back to the chamber after a high melting point metal silicide film is formed thereon in another chamber. SOLUTION: After a wafer 206 is inserted into a chamber 201, residual gas in the chamber 201 is purged by an inert gas and then the chamber 201 is evacuated thus lowering the oxygen partial pressure and the moisture concentration in the chamber 201. Subsequently, the wafer 206 is transferred into a chamber 202 and a high melting point metal silicide film is formed by sputtering and silicification reaction. Inert gas at room temperature is introduced into the chamber 201 during sputtering in order to lower the oxygen partial pressure and the moisture concentration. The wafer 206 is then transferred into the chamber 201 and cooled. The high melting point metal silicide film is protected against oxidation by controlling the oxygen partial pressure and the moisture concentration in the chamber 201 and the temperature of the wafer 206.
