Title: Manufacture of stretch type shadow mask
Inventor: HAYASHI KEIICHI
IPC: H01J29/07
Filed: 1988-11-28
Abstract: PURPOSE:To make it possible to enlarge a glass envelope, lighten its frame, and also enable fines pitches of high productivity to be formed, by uniformly stretching a very narrow metal sheet over a glass envelope formed by a part of a practically cylindrical face and having a window, and over a frame formed by a part of a practically cylindrical face, the sheet having a round or rectangular hole, and fixing the sheet to the glass envelope and the frame by welding. CONSTITUTION:The glass window portion of a vacuum envelope is formed by a practically cylindrical curved face. Its strength sufficient for withstanding atmosphere can thus be obtained. It is also comprised of an aperture mask 4 of a very narrow holed metal sheet uniformly stretched throughout it. Thermal expansion of a shadow mask during operation caused by impact of electronic beams is thereby absorbed so that apparent thermal decomposition will not occur. Color unevenness is therefore hard to occur due to miss landing even with great currents as compared to a shadow mask on a spherical face, and it is possible to realize high brightness. Also, by the use of the shadow mask made of a metal sheet thin enough as compared to its hole diameter, the time required for the process of hot-etching is shortened and its yield can be improved.

Title: Card reader
Inventor: ABE MINEO
IPC: G06K13/07
Filed: 1989-11-22
Abstract: PURPOSE:To prevent the read / write of information from being defective by backlash by detecting the number of revolution of a transmission shaft in a rotation transmitting mechanism by a rotary encoder and collecting a driving motor. CONSTITUTION:The rotating number of a transmission shaft 22b in a rotation transmitting mechanism 20 includes the backlash in the thrust direction of an output shaft 27 and the backlash of a worm 28 and a worm wheel 29 and therefore, card conveying speed is not fixed but fluctuated.

Accordingly, regardless of backlash, the rotating number of the transmission shaft 22b can be always fixed. Thus, without fluctuating the card conveying speed, the magnetic recorded information of a magnetic card 7 can be read, written and confirming without fail and high-density write is enabled.

Title: Refined and deodorized liquid ester wax and its composition
Inventor: HAYASHI YOSHIYUKI
IPC: A61K8/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for deodorizing a liquid unsaturated ester wax which is an oil of an orange roughy (Hoplosterbus altanticus) or an oil of a dory (a fish of Allocyttus sp. or Pseudocyttus maculatus) that is a natural resource, consisting essentially of a long-chain unsaturated liquid ester wax and containing an extremely readily oxidizable highly unsaturated acid and its glyceride as impurities due to the emission of a strong malodor. SOLUTION: This ester wax is deodorized by using a nickel-aluminum alloy and an alkali metallic hydroxide in combination suitable as a catalyst capable of selectively initiating the hydrogenation only for contained various highly unsaturated acids or their glycerides. Since the neutralization of the highly unsaturated acids, saponification of the glycerides and steam distillation by heat are simultaneously carried out according to the method, extremely excellent deodorizing effects are obtained. When a degumming treatment, a deacidifying treatment, a washing treatment with hot water, a filtering treatment and a heat treatment are added thereto in the method, a much higher level of the deodorization is achieved.
