Title: Method for applying resist on metal thin plate, and resist
Inventor: ONO JIRO
IPC: H05K3/06
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To form a resist film having enough adhesion property to a metal thin plate after exposure and development and to suppress residual reaction of the resist film after exposure by adding a film hardening agent to a water-soluble resist which contains casein and dichromate and has photosensitivity and applying the prepared resist on the principal plane of a metal thin plate. SOLUTION: In this method for applying the resist on the metal thin plate, the resist containing casein and dichromate and having photosensitivity to which a film hardening agent is added is applied on the principal plane of a metal thin plate. By applying the resist added with the film hardening agent on the principal plane of the metal thin plate, the resist film having enough adhesion strength to the metal thin plate can be formed after the resist is dried and the resist film formed on the principal plane of the metal plate is exposed and developed with a developer. In this process, the hardness of the developing water used for development gives little influences on the development result. The residual reaction of the resist after exposure can be decreased.

Abstract: PURPOSE:To obtain a magnified picture being interpolated while keep the continuity of a picture element by using the picture elements around a point to be interpolated, obtaining a direction, in which the respective picture elements are continued, and executing interpolation processing by using this direction. CONSTITUTION:To n pcs. of continuous point strings which are faced each other with the interpolation point between, the total sum of insulation values, which is the difference of the picture elements respectively correspondent in the arbitrary direction, is computed as a correlation value in the direction.
