Filed: 1984-04-10
Abstract: PURPOSE:To straighten camber of a substrate and to improve yield by controlling the compressive force and tension of the silicon nitride film deposited and formed on the substrate by a plasma CVD method by a plasma oscillation frequency. CONSTITUTION:An SiN film is deposited and formed by a plasma CVD method on the surface 11A part which is recessed and is not the effective part of a thin subsbrate 11 such as a filter substrate or driving element substrate of a color liquid crystal display or the like by setting plasma oscillation freqeuncy to about 50kHz if the substrate 11 is cambered downward. The stress of the SiN film is thereby provided with the tension toward the direction A by which the camber of the substrate 11 is corrected. The SiN film is deposited and formed by the plasma CVD method at about 13.56MHz frequency on the surface part 11A which projects and is not the effective part if the substrate is cambered up ward. The stress of the SiN film is then provided with the compressive force in the direction B by which the camber of the substrate 11 is straightened.

IPC: F16H61/02
Filed: 1983-04-20
Abstract: PURPOSE:To obtain a good driving performance by maintaining a certain amount of microscopic opening for a throttle valve instead of totally closing it at the time of half decelerating to secure a desired deceleration performance, while securing some amount of fuel which goes down along the inner wall face of a suction air passage, and improving the response of the fuel at the time of switching to the following driving. CONSTITUTION:At the time of half decelerating at which an accelerator pedal is released from its depressed condition to carry out deceleration for the total closing, i.e., the deceleration requirement is less than half the defined value, an output from an accelerator pedal position sensor 16, which detects that this accelerator pedal depressing amount alpha is below the first defined value, is received and judged by a third map M3, which, in turn, emits a half decelerating signal ''1'', which causes an analog switch S2 to open. Due to this opening action of the analog switch S2, the target throttle-valve opening theta for the accelerator pedal depressing amount alpha can be obtained by means of a second auxiliary map M2 and, after that, as in the case of regular driving, throttle valve opening up signals or down signals are outputted to a throttle valve opening adjusting device being compared with the actually measured throttle valve opening thereby controlling a feedback.

Title: Oxide superconductor and metal-covered superconducting wire using same
Inventor: NOMURA KATSUMI
IPC: H01B12/00
Filed: 1989-03-23
Abstract: PURPOSE:To have oxide superconductor provided with good characteristics by subjecting a powder, which is obtained by performing quick-cooling freeze drying from the synthesization temp. or provisional baking temp., to a heat treatment for sintering. CONSTITUTION:As a starting material is used a powder, which is obtained at the time of synthesization or provisional baking by performing quick-cooling freeze drying from its temp. range. To perform quick-cooling freeze drying, the quick cooling can be made using liquefied nitrogen, etc., wherein utmost case shall be paid for its atmosphere under the drying stage. Because eventual existence of moisture in the atmosphere causes dew formation, it is preferred to perform the process under the condition with no moisture contained, which is accomplished by conducting vacuum drying or carrying out in a dry atmosphere. Thereby facial adsorption of the powder is prevented, and unnecessary phase segregation or phase change is precluded, while the crushing efficiency due to microcracks is enhanced to lead to enhancement of sintering activeness, resulting in enhancement of the superconductive characteristics of the bulk material or wire.

Filed: 1989-03-22
Abstract: PURPOSE: To keep the temperature profile of a fixing roller nearly constant by controlling the actuation state of a fixing lamp arranged in the interior of the fixing roller as the function of the number of copying sheets where an image has been fixed and the size of the copying sheet. CONSTITUTION: The fixing lamp 82 is designed to generate larger energy output than the fixing lamp 90, and a control logical part 98 compares the measured number of copying sheets with the stored value of the number of sheets passing through a fixing device 62 so as to decide whether the lamps 82 and 90 are energized. Namely, the proper energizing of the lamps 82 and 90 is decided in accordance with the length of the copying sheet, and a cycle where the lamp 82 is energized for first 100 copying sheets, and the lamp 90 is energized to perform copying for the next 50 sheets and the lamp 82 is de-energized is repeated in the case the copying sheet is large. Thus, the surface of the roller 64 is set to the nearly constant temperature profile.
