Title: Laminate
Inventor: OOTA KAZUNOBU
IPC: B32B9/00
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to be suitably used mainly for a building material by making it possible to attempt to remove contaminant and harmful substance. SOLUTION: A metal layer 3 is formed on the surface of a synthetic resin base material 1, and an outer layer 6 containing titanium dioxide is formed on the layer 3 via a protective layer 5 having acid resistance. When a light is emitted to the titanium dioxide of the layer 6, the titanium dioxide is activated. Accordingly, if the contaminant made of a nitrogen oxide or sulfur oxide or harmful substance is adhered to or brought into contact with the surface of the layer 6, it is oxidized to an acid substance such as nitric acid or sulfuric acid due to the strong oxidizing power by the activation of the titanium dioxide and the presence of moisture, and the acid substance is washed or wiped off to effectively remove the contaminant or the harmful substance.  Further, even if the acid substance such as the nitric or sulfuric acid is generated, the layer 3 is protected by the layer 5, and hence the layer 3 is not corroded thereby.

Title: Opener and autoclosure drive machanism
Inventor: AZUMA CHIHARU
IPC: E05B83/36
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To easily return an open transmission element by a method wherein a drive member is engaged with a connection member, which moves back and forth between a reference position and an open position, midway in the movement of the connection member from the reference position to a release position and thereafter the drive member is disengaged. SOLUTION: When a drive member 3 is at a reference position and a motor is actuated, the member 3 rotates clockwise and a claw 47 of a ratchet claw engages with the engaging surface of a protrusion of a slider 6 to draw downward the slider 6 and an open cable 8. If the member 3 further rotates, the ratchet claw reaches a release position where it is disengaged from the protrusion, so that forces for pulling the cable 8 are eliminated and the cable 8 is returned upwardly together with the slider 6. Under such conditions, if a motor rotates reversely and the member 3 rotates counterclockwise, the claw 47 makes contact with the inclined escape surface of a protrusion of the slider 6; however, the ratchet claw rotates clockwise and moves into a recess 36, and hence the member 3 continues to rotate counterclockwise.  And the member 3 returns again to the reference position so as to be prepared for a close action.
