Title: Installing structure of metallic pipe and installing method of metallic pipe
Inventor: MAEDA TOMOYUKI
IPC: F02M55/02
Filed: 2000-04-18
Abstract: PROBLEM TO BE SOLVED: To provide an installing structure of a metallic pipe and an installing method of the metallic pipe preventing large deforming force from acting on a press-in part and a press-in object of the metallic pipe and capable of improving reliability of a metallic pipe installing part. SOLUTION: In this metallic pipe 24 pressed in a cylinder body 4, a thin part 24a as a low rigidity part is arranged in a position adjacent to the press-in part (a thick part 24b). Thus, even if some force is applied in the direction orthogonal to a shaft to the tip of the metallic pipe 24 existing on the outside, the thin part 24a is deformed before deforming the press-in part of the metallic pipe 24 and the cylinder body 4. Thus, deformation of the press-in part of the metallic pipe 24 and the cylinder body 4 can be prevented. Thus, reduction in a slipping-out load of the metallic pipe 24 is checked, and the reliability of the metallic pipe installing part can be improved.

Title: Color matching method and computer readable recording medium for recording color matching program
Inventor: IZUSHI SATOSHI
IPC: H04N1/46
Filed: 2000-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a color matching method by which a desired image can easily be reproduced without being dominated by a color in a moving direction even when a gray axis is moved. SOLUTION: A gray axis (point P) of an input device is moved so as to be coincident with a gray axis (point P') of an output device. In this case, each of data in the gamut of the input device on an equi-lightness plane is moved in the same direction attended with the gray axis movement. The moving amount of each data is smaller as the moved point of data is remoter from the gray axis (point P). Thus, the point P is coincident with the point P' and points with high saturation are not almost moved. A point (q) with high saturation has only to be moved to a closer point q' even after the adjustment of the gray axis. Thus, the color is not much changed even when the gray axis is moved.
