Title: Piston type pump
Inventor: NAKAJIMA MASAFUMI
IPC: F16J9/24
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To prevent the leak of cooling medium from a gap between a piston and a cylinder bore. SOLUTION: Two piston rings 124b are inserted into one groove 124a so that their abutments 124c can be prevented from overlapping each other in axial view of a first piston 124. In this way, two piston rings 124b are adhered to each other with compressing reaction and so two piston rings 124b can be considered as one piston ring in an O-ring shape with no abutments 124c. The leak of cooling medium is thus prevented by a simple C-shaped piston ring 124b, resulting in the increasing manufacturing cost of a compressor to be suppressed.

Title: Organic molecular film removal device using ultraviolet rays and removal thereof
Inventor: TERADA KAZUO
IPC: H01L21/336
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a simple method for completely removing an organic molecular film on a substrate. SOLUTION: An organic high-molecular film to be removed on a substrate is exposed to ultraviolet rays of a wavelength of 180 nm or shorter, whereby the film is completely decomposed and can be removed. Moreover, since the ultraviolet rays of the wavelength of 180 nm or shorter are hardly transmitted to a transparent conductive oxide, such as an ITO(indium-tin oxide), the rays can be used for removing a polyimide orientation film having defects, such as a defective printing, on a TFT array board with an ITO transparent electrode pattern formed on the surface of the structure of a TFT. By having the polyimide orientation film on the TFT array board irradiated with the rays of wavelength of 180 nm or shorter, the defect orientation film on the TFT array board can be completely removed, without giving adverse effects to the characteristics of the TFT.  After that, the defective orientation film is again sent to an orientation film forming process. Similarly, by having the TFT array board irradiated with the rays of the wavelength of 180 nm or shorter prior to an adhesion of an orientation film to the TFT array board, impurities in the TFT array board can be also removed.
