Title: Production of inactivated silicon oxide thin film
Inventor: OHASHI KAZUNORI
IPC: C23C14/58
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To substantially prevent the occurrence of contamination by the reaction with reactive gases on moisture, to enhance stability and to make cracking difficult by treating an active silicon oxide thin film formed on a substrate with a silicon based water repelling agent, thereby inactivating the surface of the silicon oxide based thin film. SOLUTION: The silicon thin film is formed on the substrate under a vacuum and this silicon thin film is changed by oxidation to the silicon oxide thin film. The surface of the silicon oxide thin film is treated with the silicon based water repelling agent to inactivate the surface of the silicon oxide thin film. A film, which exhibits a static contact angle 0 deg. with water is preferably used as the silicon oxide thin film. The silicon based water repelling agent itself reacts itsself or with the ambient moisture and has silanol groups formed on the spot. These silanol groups are presumed to react with the silanol groups on the surface of the active silicon oxide based thin film to dissipate the silanol groups and to spread inert hydrocarbon groups all over the thin film surface.  The inert hydrocarbon groups are securely bonded with the thin-film by this reaction and therefore the durability is enhanced.

Abstract: PURPOSE:To reduce uncomfortableness dependent upon tracking miss and so on, by recording information of four channel audio signals which are left side and right side signals plus the front and the back are inversed, onto information words of odd sections and even sections of the synchronizing signal respectively. CONSTITUTION:The PCM signal is blocked roughtly by the second synchronizing signal, and further, the block is blocked in details by the first synchronizing signal 1. Information L, R, l and r of four left front, right front, left back and right back channel audio signals are recorded successively onto odd-numbered section A of the first synchronizing signal 1 determined by the second synchronizing signal, and information L and R are recorded on the 13th word and the 14th word. Next, information l and r are recorded on the 1st word and the 2nd word in even-numbered section B, and similarly, information L, R, l and r are recorded successively in order. As a result, in case that a tracking miss occurs, uncomfortableness is reduced because of only change between L and l and between R and r even for exchange between odd-numbered sections and even-numbered sections.

IPC: G11B7/09
Filed: 1980-05-23
Abstract: PURPOSE:To eliminate the occurrence of the vignetting of lens of a laser beam on an objective lens by a reflecting mirror by locating the turning center of the reflecting mirror on the extension line of the reflection optical axis, and setting the turning radius thereof at the length approximately twice the optical path distance between the reflecting mirror and the objective lens. CONSTITUTION:The turning radius of a reflecting mirror 6 is set at the distance 2m about twice the optical path distance m between the reflecting mirror 6 and an objective lens 8. Now, when the mirror 6 turns by an angle phi and comes to the position 6', the incident angle of the laser beam to the lens 8 is 2phi. The laser beam irradiation position of the reflecting mirror 6 moves approximately to 2mphi. This results in that the laser beam reflected from the mirror 6 passes near the point O which is half the turning radius. Now, the lens 8 is located at the point O and this turns out that the laser beam passes always near the center of the lens 8, thereby eliminating the vignetting of lens of the laser beam owing to tracking.
