Title: Fine etching of transparent conductive film
Inventor: AKAZAWA MASASHI
IPC: H01B13/00
Filed: 1982-01-26
Abstract: PURPOSE:To enable fine etching of high accuracy in etching a substrate having a transparent conductive film in patternlike manner by using metallic pattern formed by photoselective plating as resist. CONSTITUTION:A substrate 2 having a transparent conductive film 1 consisting of tin oxide, indium oxide or their mixture is immersed in dilute aqueous solution of stannous halide about 1min to make the surface of the substrate adsorb divalent tin ions 3 in colloidal state. After drying, it is exposed to light containing ultraviolet rays of wavelength of 250-300nm through a photomask. In the exposed part, divalent tin changes to tetravalent and loses reducing force. When it is immersed in an aqueous solution containing Pd, silver and copper ions, these metals are reduced by divalent tin, and particles of metal that become nuclei of plating deposit with the photomask in positive pattern. Then, it is immersed in nonelectrolytic plating solution to obtain a metallic coating 4, and this is used as resist to etch the film 1. Then, the coating 4 is stripped by dissolving and desired transparent conductive film pattern is obtained.

Title: Magnetic disk device
Inventor: YANAGISAWA MASAHIRO
IPC: G11B33/12
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To suppress decrease in thickness a lubricant film to a min. by possessing a side surface opposite to a circumferential end surface of a magnetic disk plate and setting a space between the circumferential end surface of the magnetic disk plate and an inner wall surface of a side wall opposite to the circumferential end surface to >=0.10mm. SOLUTION: Air flows toward the outside in the radial direction in a space 23 between the rotating magnetic disk plate 11 and the inner side wall surface concerned, for instance, a space 12 between the plates 11 or a space between the plate 11 and the inner side wall surface of an upper lid 24 and a space between the plate 11 and the inner side wall surface of a lower lid 25 or in the vicinities of the circumferential end surface 27 of the plate 11 and the surface of the plate 11. Furthermore, an airflow 18 is generated along the rotating direction of the plate 11. A flowing speed distribution is dependent on a Reynold's number R, and when rotational angular velocity and kinetic viscosity are constant respectively, the smaller the number R and the smaller the space d (the spaces 12, 19 and 23 relative of the plates 11), the nearer to zero becomes the flowing speed V.  This effect is synergetically exhibited in proportion to smaller size of the spaces 12 and 23 respectively. The smaller the space 19 between the circumferential end surface 27 and the side wall 26, the smaller a decreasing rate of the film thickness of a liquid lubricant 20.
