Inventor: MORI NOBUYOSHI
IPC: G02B15/16
Filed: 1989-12-12
Abstract: PURPOSE:To obtain an about twice variable magnification ratio and to use the zoom lens without using any special correcting means in the case of environmental changes in temperature and humidity by arranging a lens made of a moisture absorptive material between moisture-nonabsorptive lenses, and sealing the moisture absorptive lens with a lens holding member and eliminating a vapor exchange with the outside field. CONSTITUTION:Acryl-based plastic 2 is used for a 3rd and a 6th lens. The acryl-based plastic is easily affected by humidity variation and when the lens is used, an image is deteriorated greatly unless temperature variation and humidity variation are both compensated. For the purpose, by forming a sealed structure with the lens holding member 1, only the temperature variation needs to be compensated. Aluminum or plastic is used preferably for the lens holding member 1. Namely, the moisture nonabsorptive lenses are arranged at both ends in the optical axis direction and the moisture absorptive lens 2 arranged in the intermediate section is sealed hermetically with the moisture nonabsorptive lenses at both ends and the lens holding member 1. Consequently, the influence of the humidity variation is eliminated and the temperature variation is also compensated excellently to obtain the low-cost, compact zoom lens which displays excellent performance even in various environments.

IPC: H01L21/205
Filed: 1987-12-22
Abstract: PURPOSE:To remove a substrate surface oxides at a relatively low temperature, by vaporizing gallium in a vacuum on the surface oxide film of a substrate and forming a gallium oxide by treating gallium with heat, thereby heating and pyrolyzing the gallium oxide in an atmosphere of arsenic. CONSTITUTION:Gallium is vaporized to the same thickness as that of an SiO2 film or more in a high vacuum on the oxide film 2 of an Si substrate 1. When the whole body of the substrate 1 is heated to about 500 deg.C, a reaction takes place at the surface of the substrate and then, gallium oxide Ga2O3 and an oxide film 2 are reduced to form Si. After that, if the substrate 1 is heated to about 580-600 deg.C, while irradiating arsenic, Ga2O3 is thermally decomposed. The arsenic is used as catalyst. SiO2 on the substrate 1 is thus removed and the surface is cleaned.
