Filed: 1994-12-20
Abstract: PURPOSE: To form a display pattern according to the presence of a reflection layer and to obtain a display part with high contrast by partially forming the reflection layer on a non-information recording surface in an optical disk. CONSTITUTION: An information recording medium 13 having a pit 12 carrying information and a non-information recording medium 15 having the pit 14 carrying a dummy signal are formed on one surface of a light transmissive substrate 11 made of synthetic resin, and the reflection layer 16 consisting of a metal thin layer is partially formed on the non-information recording medium 15 to form the display part. That is, the display part is formed by the formation of the part on which no reflection layer 16 is formed or the shape of the part on which the reflection layer 16 is formed. Thus, the display pattern is formed according to the presence of the reflection layer of the non-information recording area, and the contrast is enhanced.

IPC: H01C7/12
Filed: 1991-12-19
Abstract: PURPOSE:To contrive to lighten without reducing the durability against inner pressure increase at the time of generation of inside arc as compared with the conventional constitution and reduce a price. CONSTITUTION:A thickness of a cylindrical part excluding bolt parts 11, 12 at both ends of an insulating cylinder 1A receiving an arrester element 10 is substantially same in the dimension as that of a valley part of the bolt parts 11, 12, whereby the insulating cylinder 1A, or the arrester, is lightened.
