Abstract: PURPOSE:To permit determination of an adequate fixing assurance temp. and to eliminate wastefulness such as unnecessary copying interruption of a machine while assuring the fixability by changing the fixability assurance temp. by the output of a thermistor and executing the temp. control of a fixing roller when the total number of copies after supply of a power source attains a prescribed number of copies or the prescribed time elapses. CONSTITUTION:A case in which the temp. of the fixing roller 1 varies with an atmosphere temp. arises even if the output of the thermistor 5 is the same in the case of pressing the thermistor 5 to the peripheral face of the fixing roller and detecting the temp. thereof. The temp. of the fixing roller is, therefore, controlled by adopting the output R1 of the thermistor 5 when the total number of copies attains the prescribed number of copies after the supply of the power source to the copying machine or after the prescribed time elapses and adopting the output R2 smaller than R1 during the time before said attainment of time lapse respectively as the substitution values of the fixability assurance temp. in the case of controlling the fixing by deciding the fixability assurance temp. from the detected output of the thermistor 5. The fixing is thereby effectively controlled without wastefulness.

Title: Mosfet on the basis of gallium arsenic and its product
Inventor: CHO ALFRED Y
IPC: H01L21/336
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To form the alloy of an ohmic metal contact by allowing a gate oxide layer of a product including a metal/oxide/semiconductor field effect transistor on the basis of a first GaAs where a gate metal contact is arranged on a gate oxide layer as a base to be Gd-Ga oxide with a specific Gd:Ga atom ratio. SOLUTION: A protection dielectric layer is formed by depositing SiO2 . The formation of an alloy of an ohmic metal is performed at a temperature within a range of, for example, 400±50 deg.C in He atmosphere in a typical case. The elimination of the protection dielectric requires strictness for preventing the gate oxide from being damaged. More specifically, the composition of the gate oxide is selected properly, namely a Gd-Ga oxide with a Gd-Ga ratio that is 1:7.5 or preferably 1:4 or 1:2 or larger. The etching speed of Gd-Ga oxide in an HF solution depends on the Gd content of the oxide. Therefore, the protection dielectric on the gate oxide can be eliminated without losing the gate oxide and the alloy of the ohmic metal contact can be formed.
