Title: Optical recording medium
Inventor: SUMI TAKAO
IPC: G11B7/243
Filed: 1986-10-31
Abstract: PURPOSE:To greatly enhance heat resistance and light resistance of an optical recording medium at the time of projecting laser light onto the medium for reproduction and increase the number of times the medium can be used, by providing an active metallic oxide layer on a substrate to be coated, and allowing a light-absorbing material to be contained in micropores in the layer. CONSTITUTION:For an active metallic oxide layer provided on a substrate to be coated, a transparent metallic oxide such as activated alumina and activated silica is used. The transparent active metallic oxide layer is provided by, for example, applying a composition having favorable application properties, such as an alumina sol and a silica sol, to the substrate to be coated, and then drying and baking the applied material. A light-absorbing material is allowed to be contained in micropores in the metallic oxide layer. An organic coloring matter having absorptivity at the wavelength of a semiconductor laser and capable of being adsorbed on the metallic oxide layer can be used as the light- absorbing material. Particularly, naphthoquinone, anthraquinone and phthalocyanine coloring matters are effective.

Abstract: PURPOSE:To decrease the floor area to be excavated and reduce a term of setting works, by installing an upper cover to be fixed by an upper cover setting leg, set to the upper surface of a high rigid casing, and enabling a supporting length of an upper cover arm and the setting leg to be reduced. CONSTITUTION:A high rigid casing 5 secures to its upper pat an upper cover setting leg 13, while this setting leg 13 sets an upper cover 7, arranged protruding from a housing 4, to be fixed. In this way, a supporting length of an upper cover arm 7c and the setting leg 13 can be reduced. As a result, the manufacturing cost of a setting part can be reduced while the deformation at concrete placing time can be suppressed because of no necessity for increasing the rigidity as in the past. Further a term of setting works can be reduced because the works both reduce an excavation area of base rock and require only one time concrete placing.

Filed: 1988-10-19
Abstract: PURPOSE:To obtain the quality of a stable conveyance by putting an endless conveying belt between a follower roller near to the downstream side of a photosensitive body and a driving roller of a paper ejecting part so that the conveying belt may be sandwiched between a pair of fixation rollers. CONSTITUTION:A transfer paper 2 after transferred is conveyed to the direction of the pair of the fixation rollers 9 by the endless transfer belt 8 which is put between the follower roller 6 disposed near to the downstream side of the photosensitive body 1 and the driving roller 7 which also functions as a paper ejecting roller disposed below. The pair of paper ejecting rollers are constituted of the paper ejecting roller 12 on the upper side and the roller 7. When the transfer paper 2 is brought into to be held between the fixation roller 14 and a pressurizing roller 15, the paper 2 is ordinarily shocked at the thickness of the paper and a transfer part is influenced by the shock, so that the transfer blur sometimes occurs. But by this constitution, since the transfer paper 2 is conveyed as closely contacting to the belt 8, the transfer blur cannot occur. And the quality of the stable conveyance can be obtained by integrating a conveying system such as the conveying paper after transfer, the fixation part and the paper ejecting part.
