IPC: B32B33/00
Filed: 1987-04-30
Abstract: PURPOSE:To obtain a decorative body which improves a decorative effect and is favorable in adhesion, hard to generate peeling of coating and in a mat or satin tone, by a method wherein the higher it goes upward on a coating layer the greater a containing rate of a pulverulent body increases gradually and a layer to which the pulverulent body is not added is interposed between a base material and the coating layer. CONSTITUTION:A layer 2 to which a pulverulent body is not added is provided on a metallic base material 1 and coating layers 3a, 3b wherein the higher it goes upward on the layer 2 the greater a containing rate of the pulverulent body increases gradually are provided on the layer 2. It is preferable that almost 1-50wt.% for a first layer 3a and 5-60wt.% for a second layer 3b are used for solid content of coating as a content of the pulverulent body, though they are varied according to a kind of the pulverulent body. Adhesion of the coating layer to the base material is improved by providing the layer 2 wherein the pulverulent body is not added on the base material. A reduction of a quantity of the pulverulent body containing within the coating layer is mitigated further by providing the coating layer wherein the higher it goes upward on the coating layer the greater the containing rate of the pulverulent body increase gradually. A decorative body possesses the coating layer, which is high in a decorative effect and in a mat or satin tone, is favorable in adhesion and becomes hard to generate peeling of the coating.

Title: Junction block
Inventor: MIYAMOTO TAKASHI
IPC: H02G3/16
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a junction block for detecting not only the placement state of a connector but also that of a retainer. SOLUTION: A detection piece 44 is provided at one portion of a detection block 30. Then, the height up to the detection piece 44 is set slightly larger than up to the upper end of a first connector 14 in a completely fitted state. Also, the height up to the detection piece 44 is slightly larger than the height of a retainer 21 in a completely fitted state. Therefore, when the first connector 14 is not completely fitted, a detection block 30 is not moved from a non- detection position to a detection position. Also, when the retainer 21 is not been fitted completely, the detection block 30 does not move to the detection position. Therefore, since the fitment of a second connector 15 is prevented, the fitment state of the first connector 14 and the retainer 21 can be detected.

Abstract: PURPOSE:To maintain tensile force of each chain at the same level to keep normal operation by controlling chain drive devices provided separately to every chain train so that driving current values of the chain drive devices are equal to each other even when lengths of the right and left chains are subjected to secular change. CONSTITUTION:Rotational speed indicators 10 are provided respectively to driving sprockets 2a, 2b, ammeters 11 are provided to respective drive motors 6, and the difference in current values is computed by a computing element 12. A control device 8 controls the respective drive motors 6 so that the differ ence in current values of the motors becomes zero. At this time, the driving sprockets 2a, 2b are controlled by means of the speed indicators 10 so that no large speed difference is produced between the sprockets 2a, 2b. As control devices 8 for current of the induction motor 6, various types of control means, for example, primary voltage control, primary frequency control, secondary resistance control are utilized. Thus, since chains 1a, 1b are driven while maintaining the same tensile force constantly, each chain is not disengaged from either one of driving sprockets.

IPC: G11B7/2433
Filed: 1983-06-16
Abstract: PURPOSE:To obtain a memory material which is densely crystalline and provides a high recording density by forming a thin chalcogen glass film in which Se and Ga has a compsn. of a specific ratio on the surface of an org. resin material and coating the surface of the thin chalcogen glass film with a transparent org. resin material. CONSTITUTION:A thin chalcogen glass film having a compsn. contg., by molar %, 85-95% Se and 3-15% Ga is formed on the surface of an org. resin material and the surface of the thin chalcogen glass film is coated with a transparent org. resin material. The thin Ga-Se chalcogen glass film is formed by an ordinary vacuum deposition method. Said film is an amorphous and optically transparent body right after formation but when strong light, for example, the light of a xenon lamp is condensed and irradiated thereto, the film can be changed to a crystalline material having a low transmittivity. The crystallized thin Ga-Se film can be returned to the amorphous state by irradiating the strong laser beam throttled with an optical lens thereto for short time. The crystallization of the amorphous state is further achieved by irradiating the laser beam having the lower intensity than the above-described laser beam to said film.
