Title: Screen device
Inventor: ISHII HIROKAZU
IPC: G03B21/60
Filed: 1978-05-30
Abstract: PURPOSE: To make possible desired selection of directional angles and achieve the evenness of directional angles by forming plural convex parts at a specified spacing on one surface of a film sheet and evaporating an aluminum film on the convex part surfaces.  
     CONSTITUTION: Concave parts 2 are formed at a spacing of, e.g., about 0.5 to 0.8 mm, by pressing with a press or the like, on one surface of a film sheet 1 constituted by transparent resin or the like and an aluminum film 3 is evaporated on the surface of the convex parts 2, i.e., one surface of the sheet 1. The other side of the sheet 1 is used as a screen. The sheet 1 is extremely soft and permits easy formation of the concave parts 2 having directional angles of ±10° in the vertical directions and ±20° in the horizontal directions through pressing. In addition, the sheet 1 plays the role as a protecting function of the aluminum film 3 and therefore even if the screen is cleaned, flawing of the aluminum film 3 will not occur. This enables the directional angles to be selected as desired and enables the directional angles to be evened.

Abstract: PURPOSE:To make it possible to form specified circuits by an electroless plating method on an electric insulating layer without decreasing insulation reliability between the circuits, by forming a separable resist layer beforehand at a part where a circuit is not formed on the surface of the electric insulating layer, and separating the separable resist layer after the activation of a catalyst. CONSTITUTION:After a catalyst on the surface of an electric insulating layer 1 is activated, electroless plating is performed. Thus a circuit is formed. When a printed wiring board is manufactured in this way, a separable resist layer 5 is formed beforehand on a part where a circuit is not formed on the surface of the electric insulating layer 1. After the catalyst is activated, the separable resist layer 5 is separated, and a catalyst active layer 2 is formed selectively only at a part where the circuit is formed. Thereafter, electroless plating is performed, and a specified circuit 3 is obtained. As the said separable resist layer 5, a material having the following property can be used: the material that is resistant to aqueous solution of hydrochloric acid of palladium chloride; the material that does not hinder the activation of the catalyst at the circuit forming part; and the material that can be separated after the activation of the catalyst. As the separating method, it is desirable that the separation can be simply performed manually since the separation can be ensured.
