According to an embodiment, a gas insulation apparatus (e.g., a gas circuit breaker) includes a high-voltage unit, a zeolite and an insulation gas in a closed vessel. The insulation gas is COgas or a gas including COgas as the main component. The zeolite is contained in a zeolite case and is placed under an insulation gas atmosphere. COis adsorbed on the zeolite before use of the gas insulation apparatus.

An optical disk comprises a mark train, which has at least one shortest mark and at least one other mark, recording readable information by applying a light beam, wherein the shortest mark of the mark train have a width larger than that of the other mark.

Optical disk and method of manufacturing the same

An optical disk has first and second substrates, at least one of which is provided with optically readable pits corresponding to record data, and a reflection film coated on the pits. In the optical disk, the first and second substrates are laminated on each other such that the surface on which the pits are formed, is located inside. Label information, indicative of the record data, is formed on at least one of the surfaces of the first and second substrates, which contact each other.
