Title: Film forming device of thin film and method of forming thin film
Inventor: INAI TAKAAKI
IPC: C23C16/44
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To remove deposition inside a reaction chamber in a short time securely without corroding the inside of the reaction chamber by supplying steam and hydrofluoric acid anhydride simultaneously for removing the deposition inside the reaction chamber in forming an Si oxide film on a substrate. SOLUTION: After mounting a sheet form substrate 2 on a substrate mounting base 3 arranged inside a sealed reaction chamber 1, the inside of the reaction chamber 1 is evacuated. When the film forming of the Si oxide film is performed on the sheet form substrate 2, the Si oxide film is deposited not only on the sheet form substrate 2 but also on components inside the reaction chamber. The inside of the reaction chamber 1 is kept evacuated after the sheet form substrate 2 is taken out from it for the removal of the deposition inside the reaction chamber 1. The deposition in a blow out hole made of fluoroethylene resin and in the reaction chamber 1 is removed by supplying the hydrofluoric acid anhydride and the steam simultaneously through the gas supplying pipes 6a that are plumbed branching from a reaction gas supplying pipe 4.  With this, the deposition inside the reaction chamber 1 can be removed in a short time securely.

Title: Binding tape heater, binding tape heating device and binding device
Inventor: OTA YUTAKA
IPC: B65H37/04
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To conduct heating so that a hot melt adhesive on a binding tape may not come out from both ends in the longitudinal direction of the tape. SOLUTION: Void parts 712b, 712c are formed at an area where both ends in the longitudinal direction of a binding tape T are positioned on the plane part (heater surface) of a protective member 712 for protecting a ceramic heater part 710. The void parts 712b, 712c make heat generation of the ceramic heater 710 difficult to transmit to the binding tape T, thus making a hot melt adhesive layer B1 at both ends in the longitudinal direction on the binding tape T difficult to melt. It is thus possible to inhibit the hot melt adhesive layer B1 from coming out from both the ends in the longitudinal direction of the binding tape T.

Title: Speed selecting mechanism of automatic transmission
Inventor: MIURA MASAKATSU
IPC: F16H63/12
Filed: 1983-05-11
Abstract: PURPOSE:To increase the force required for making D-2 shift to an extent which is equal to or less than a specific % from the force required for making N-D shift, by setting the inclination of the section from the D (drive) position of a detent lever to the 2 position more steeply than the inclination of the section from the N (neutral) position to the D position. CONSTITUTION:A detent mechanism 3 has a plate-like shape which is fixed to one end of a shift lever shaft 21 and makes rotation around the shaft 21, and, at the outer periphery which is the acting margin of the mechanism 3, notches p, r, n, d, s, and l corresponding to the setting position P, R, N, D, S, and L of a shift lever are continuously installed. The inclination 37 of the section at the notch (d) side between the notches (d) and (s) of a detent lever 31 is set more steeply than the inclined line 39 of the section at the notch (n) side between the notches (n) and (d) and, therefore, force which is 15-50% stronger than the force required for shifting the shift lever from the N position to the D position, is required when the shift lever is moved from the D position to the S position. As a result, wrong shifting of the shift lever from the N position to the S position through the D position can be prevented, because a considerable reaction can be felt before the shift lever moves from the D position to the S position.
