Title: Cleaning device for seal surface of cathode-ray tube panel
Inventor: TAGUCHI TETSUJI
IPC: H01J9/46
Filed: 1987-11-17
Abstract: PURPOSE:To improve cleaning effect of a panel seal surface by arranging a vacuum cup above a cleaning conveyor, holding the panel with the vacuum cup, and rubbing the panel seal surface with rollers wetted with cleaning liquid. CONSTITUTION:A vacuum cup 15 is lowered relative to the surface of a panel P supported with conveying and cleaning rollers 12 of a cleaning conveyor 13. While sucking the panel P with the vacuum cup 15, a seal surface of the panel P is pressed against the rollers 12 by means of a specified load. Under this condition, the seal surface of the panel P is rubbed with rollers 12 by reciprocating the vacuum cup 15 in both same and opposite directions of the conveyor while rotating the rollers 12. This makes it possible to effectively clean the seal surface of the panel P.

Title: Joint structure for preventing outflow of back-filling material
Inventor: KAWAKAMI CHITOSE
IPC: E02B3/16
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To strengthen a joint filler by a method wherein stress materials are arranged among supporting materials installed at regular intervals in order to connect the longitudinal direction of the mutual supporting materials, the supporting materials and the stress materials are buried into an elastic body and unified with the joint filler, and mounted on the back of a joint. SOLUTION: The rear of a joint 8 is stuffed with the back-filling material 10 such as soil and sand, and a joint filler 1 is penetrated so as to be curved into the joint 8 and correspond to earth pressure by the back-filling material 10 and wave pressure by backwash. When caissons 6 are moved by the uneven settlement, etc., of the caissons 6 after the installation of the caissons 6, a stress material 4 resists left-right and upper-lower and before-behind movement. Consequently, the fixing section of the joint filler 1 resists the movement by supporting materials 3, and can resist them up to the strength limit of the stress material 4. When the stress material 4 is buried under a loosened state, the stress material 4 can follow up to the shifting of the caissons 6 up to a stretched state. Accordingly, since the joint filler 1 is fixed onto the caissons 6 through the supporting materials 3, the fixing section can resist stress firmly.
