Abstract: PURPOSE:To obtain a superthin film free of defects such as pinholes, etc., by a method in which a polyquinazolone polymer of a specific structure is dissolved in a specific liquid saturated halogenated hydrocarbon solution, and the solution is coated on a supporter and then the solvent is vaporized. CONSTITUTION:A polyquinazolone polymer having a bisquinazolone repeating unit of the formula I (where R<1> is a tetravalent organic group, R<2> is each independently an alkyl or an aromatic group, and R<3> is a divalent organic group) is dissolved in a liquid saturated halogenated hydrocarbon solution having one or two carbons whose at least one carbon is substituted with at least two halogen atoms to prepare a coating liquid. The coating liquid is coated on a supporter, e.g., glass, stainless steel, synthetic resin plate, etc., and then coagulated by vaporizing the solvent to form a polyquinazolone polymer film.

Title: Single-acting double pen cylinder
Inventor: USHIYAMA TAKAHIRO
IPC: F15B15/16
Filed: 1981-09-21
Abstract: PURPOSE:To make a space for machinery small by providing double built-in spindles which act by means of compressed air from a cylinder tube and uniting cylinders into a single body. CONSTITUTION:By means of compressed air admitted through a compressed air infusion port 9, and also because a spring 6 has less elastic force than a spring 7, a spindle 5 advances to its maximum and strikes against a catching part 10 of a spindle 2, which is pushed forward. When compressed air is shut out from infusion, both spindles 2, 5 are restored to their former condition. In such a configuration, since an operational distance of a spindle may be doubled and cylinder may be united into a single body even with a short cylinder tube,a space for  machinery may be lessened.

Title: Reclining mechanism which uses spring of spring
Inventor: MATSUMOTO NOZOMI
IPC: F16F7/06
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation of rotation speed due to temperature by providing a slide contact member which is deformed to increase contact pressure when a temperature rises high in a panel turning mechanism such as an acoustic equipment which limits rotation speed by an oil damper. SOLUTION: A panel 1 is energized counterclockwise by a torsion coil spring 8 mounted on a shaft 3a. An intermediate gear 4 supported rotatably meshes with a gear 1a and further meshes with a small gear 5a of an oil damper 5. A slide contact member 7 made of a material having high coefficient of thermal expansion is bonded to a support metal fitting 6 to come in slide-contact with a slide-contact face 1d of the panel 1. When a lock is released, the panel 1 turns due to spring of a torsion coil spring 8. When a temperature rises, resistance torque of the oil damper 5 is reduced, but the slide contact member 7 is expanded to increase friction resistance so as to limit turn speed of the panel 1. The slide contact member 7 may be constituted by bimetal and one end thereof may be in slide-contact with the panel.  Consequently, it is possible to reduce the fluctuation of turn speed and increase a commercial value of a product.
