Title: Disk valve
Inventor: KOSHIDA MICHIHIKO
IPC: C23C16/26
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a disk valve which can maintain an excellent sliding property for a long period, has an excellent abrasion-proof property, and has a long service life. SOLUTION: Hydrogen is included in a diamond form hard carbon film 34, and the hydrogen including amount is made less than 35 atomic %. That is, the diamond form hard carbon film 34 whose hydrogen including amount is made less than 35 atomic % has more than 10GPa in the Knoop hardness (HK), and as a result, it is never abraded in a short time even in the sliding condition with a movable valve body 20, and an excellent sliding property by the self lubricating function of the film 34 itself can be maintained for a long period. In this case, the expression that the hydrogen including amount in the film is less than 35 atomic %, means that along the whole body of the film 34 from the front layer to the film thickness T, the hydrogen including amount is made less than 35 atomic % uniformly.

IPC: G01B11/30
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To provide an inspection apparatus for a flaw, by which the flaw on a plane can be inspected even when a disturbance such as an oil bubble or the like exists. SOLUTION: This apparatus is used to inspect a flaw on the surface of an AT valve plate in which a plurality of holes are formed and to which an oil is stuck.

The image processor 6 sequentially performs a gray processing operation and a binarization processing operation to a camera image, and it extracts a region having a luminance value which is about the same as a flaw part B. Then, on the basis of a length ratio regarding the extracted region, whether the extracted region indicates a flaw or an oil bubble is judged. In addition, on the basis of a change in the luminance value around the extracted region, a region which is based on a plate edge is discriminated. Thereby, only the flaw can be extracted, and the accuracy of the inspection of the flaw can be enhanced.
