Title: Selective etching method for aluminum oxide thin film
Inventor: TONOYA JIYUNICHI
IPC: H01L21/3065
Filed: 1995-02-27
Abstract: PURPOSE: To etch an aluminum oxide thin film at a high selection ration with aluminum or silicon by containing a saturated or non-saturated carbon and hydrogen gases which contain a boron trichloride gas and fluorine or a non- saturated carbon hydrogen gas and a CO gas or CO2 as an etching gas. CONSTITUTION: The amount of Al etching and AlOx is determined with a contact type offset meter. When total amount of CHF3 gas and CO gas, which occupy the etching gas is increased, the etching rate of both AlOx and Al is decreased. When the total amount of the gas exceeds 120SCcm, the Al etching approaches about zero, which reverses the etching rate of the AlOx and Al. It is therefore, possible to use the process effectively for patterning an aluminum oxide thin film of a semiconductor device or a liquid crystal display device.

Title: Internal-combustion engine having wall face of combustion chamber applied with heat insulating layer
Inventor: KISHISHITA TAKAHARU
IPC: F02B77/11
Filed: 1984-03-02
Abstract: PURPOSE:To produce an internal-combustion engine having excellent volume efficiency while maintaining the insulating effect by covering the wall face of combustion chamber with carbon cloth having surface applied with heat-resistant metal film layer. CONSTITUTION:An insulating member where a heat-resistant metal layer 3 is applied onto a carbon cloth 2 is applied onto the top face of member for forming the wall face of combustion chamber of internal-combustion engine or a piston 1. Preferably, the thickness of the carbon cloth 2 is shorter than 2mm. while nickel or titanium film having the thickness shorter than 0.1mm., for example, is employed as the heat-resistant metal layer 3. Consequently, the insulation performance is improved because of the heat-resistant metal layer 3 applied onto the carbon cloth 2 where the thermal capacity can be reduced because of low heat transmission factor of the carbon cloth 2 while since holding of high temperature gas in the carbon cloth 2 is prevented, the volume efficiency can be improved.

Filed: 1992-01-29
Abstract: PURPOSE:To stabilize an electrode potential of a pH electrode using metal or metal oxide for pH-sensitive film easily in a short time, and facilitate calibra tion operation. CONSTITUTION:After completion of measurement, pH electrode 30 and a comparison electrode 10 are contained in an adaptor 1 attached to a device main body, and electrodes 30, 10 are immersed in solution 15 of pH6.86, which is similar to that of inner liquid 13 of the comparison electrode 10, injected inside it. Electrode plugs of the electrodes 30, 10 are connected to a pH terminal 2 and a comparison terminal 3, and a switch 4 is put on, so the pH electrode 30 and the comparison electrode 10 are shortcircuitted. An electrode potential of the pH electrode 30 is thus returned to its original condition soon to be stabilized. In the meanwhile, the pH terminal of the device main body is shortcircuitted with the comparison terminal, and a gauge pointing value is set at pH6.86. Calibration for one point can thus be performed electrically, thereby need of complicated calibration operation can be eliminated.

Title: Magnetic disc device
Inventor: FUJII TERU
IPC: G11B23/00
Filed: 1985-03-01
Abstract: PURPOSE:To facilitate the assembly of a magnetic disc, a spacer, and a spindle with high precision and to perform the assembling work efficiently by interposing a fluororesin member between the magnetic disc and the fitting part of the spacer and the spindle. CONSTITUTION:A fluororesin film 11 is formed on a fitting surface 10, which is fitted to the spindle, of an assembling hole 9 provided in the center of a magnetic disc 4A having a magnetic paint coated surface 8. Thus, building-in by fitting is facilitated because a coefficient of friction is reduced by one digit or more in comparison with the use of fitting parts consisting of Al together, and the generation of worn powder due to contacting between two parts for building-in by fitting is prevented because the viscosity of the fluororesin is higher than that of Al. Consequently, it is unnecessary to use a conventionally required means, namely, assembling without contacting which avoids pinch, and automatization of the assembling work is facilitated.
