Title: Wall-mount remote controller
Inventor: UMEHARA CHIKAHIRO
IPC: F24H1/00
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent packings from being twisted when a remote controller is inserted into a mounting plate. SOLUTION: After packings 60 are stuck to both surfaces of a mount plate 50, the mount plate 50 is fixed to a wall surface 1 with screws and the main body 10 of a remote controller 10 is obliquely inserted into the plate 50 along a guide piece 54 from above. When the main body 10 is obliquely inserted into the plate 50 from above, the main body 10 can be inserted into the plate 50 without twisting the packings 60, because the downward forces applied to the packings 60 between the main body 10 and plate 50 can be reduced. After inserting the main body 10, the main body 10 is fixed to the plate 50 by screwing screws 2 in the tapped holes 56 of the plate 50 through fixing holes 35 provided in the lower section of the main body 10.

Abstract: PROBLEM TO BE SOLVED: To make the position of a moving piece visually observable and accurately output it via an electric signal, by detecting the reflected light from the moving piece in a transparent taper tube with a digital image sensor. SOLUTION: A moving piece 2 made of white Teflon (R) is vertically moved in a taper tube 1 made of a transparent material by the fluid force of a measured fluid. The moving piece 2 is illuminated by a light source 3 illuminating the whole moving region.

Title: Original platen cover
Inventor: ATOMICHI TAKAHIRO
IPC: G03G15/04
Filed: 1989-12-25
Abstract: PURPOSE:To detect the opening and closing angle of a means covering an original platen by detecting the opening and closing of an original platen cover by using a variable resistance. CONSTITUTION:The original platen cover 2 is opened and closed at a fulcrum A. When an actuator 4 exists uppermost, the resistance value of a slide volume 3 is 10kOMEGA and when the actuator 4 exists lowermost, the resistance value of the slide volume 3 is 0OMEGA. The resistance value of the slide volume 3 is consecutively changed with the movement of the actuator 4. Namely, the actuator 4 exists uppermost when the cover 2 is opened and it comes into contact with the cover 2 when the cover 2 is closed to a certain position. As the cover 2 is gradually closed further, the actuator 4 moves downward and when the cover 2 is perfectly closed, the actuator 4 stops a little upper than the lowermost part. Thus, the angle of the original platen cover is detected.
