Title: Magnetic disk device
Inventor: HONDA SHOHEI
IPC: G11B23/00
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a joining structure of a disk which does not cause devia tion of the disk when impact is applied. SOLUTION: In the disk fixing structure of the magnetic disk device, the disks 1a, 1b are stuck to spacers 2a, 2b which are processed with screw cutting in the inside diameter. The spacers 2a, 2b are fixed to a hub 4 which is processed with screw cutting in the outside diameter. Depending on the joining structure, the inside diameter of a member which is mounted on the hub and the outside diameter of the hub are processed with screw cutting, the member to be mounted is directly screwed and fixed, and therefore, the structure which does not cause deviation of the mounted member is afforded due to metallic contact of the screw part. Thus, the deviation of the disk does not occur.

IPC: C03C15/00
Filed: 1994-08-26
Abstract: PURPOSE: To set a position determining mark in light exposure and separation and to improve processing accuracy by irradiating a photosensitive glass material with excimer laser in a method for exposing the photosensitive glass material, separating, etching, etc. CONSTITUTION: A photosensitive glass material is exposed by using a photomask having formed an exposable pattern simultaneously on plural part materials and the exposed materials are cut and separated into plural part materials. The separated part materials are provided with desired channels, etc., by a process including thermal development and etching. In the processing method, before the cutting and before or after light exposure, the photosensitive glass materials are irradiated with excimer laser at fixed positions.

CONSTITUTION:Anodic gas flowing through each of anodic-gas passages 1A diffuses through a water- repellent porous base-material 5C to reach an anode 4. At this time, the anodic gas is split into a part thereof that diffuses through the water-repellent porous base-material 5C to directly reach the anode 4 and the rest thereof that bubbles in water flowing through each of water-flow passages 5B to indirectly reach the anode 4 so as to by uniformly supplied all over the surface of the anode 4. Water is sufficiently supplied to a fluororesineous cation exchange film 3 through the anode 4 from the water-flow passage 5B so as to maintain the hydrated condition of the film. Since the water flows through the water-flow passage 5B, a head loss is small and the water is easily supplied from outside the cell. Thus reaction gas may be uniformly supplied to the anode while water may be supplied easily to the anode.
