Title: Pressure developing device
Inventor: HOSAKA YASUO
IPC: G03G15/08
Filed: 1978-12-07
Abstract: PURPOSE:To perform development free from ground stains by forming a pressure roller with expandable material. CONSTITUTION:The pressure roller 3 of a pressure development device 2 which develops electrostatic latent images formed on a photosensitive drum 1 is formed by covering a thin film 32 composed of conductive material on the surface of a roller body 31 composed of expandable conductive elastic material. If with this arrangement the force for pressing the pressure roller 3 to the photosensitive surface of the photosensitive drum 1 is set relatively large, the pressure being exerted per unit area of the photosensitive surface becomes extremely small, whereby the occurrence of the physical deposition of developer is prevented. Hence, when the magnetic brush formed on the ouside circumferntial surface of a sleeve 43 is deposited on the surface of the pressure roller 3 and the developer is deposited on the electrostatic latent images formed on the photosensitive surface through contact with the photosensitive surface of the photosensitive drum 1, the stable development free from ground stains as against mechanical vibrations of the device is accomplished.

IPC: B62M3/08
Filed: 1993-06-23
Abstract: PURPOSE:To provide pedals for a bicycle which can be coped with to be used after the procedure of use is sufficiently mastered. CONSTITUTION:A preventing means body 8a is mounted on a cleat storing part 11 by a mounting screw 8b. When the preventing means body 8a is left mounted, the cleat is not inserted into the cleat storing part 11, and the engagement of the cleat with locking bodies 6, 7 is impossible, and the shoes can not be connected to the pedals. The head part of the mounting screw 8b is formed to be of special shape so that the removal of the mounting screw 8b may only be executed by using an exclusive removing tool 16. This constitution allows the exclusive removing tool 16 to be stored at the specified part, and releases the prevention of engagement between the cleat and the locking bodies 6, 7 by the preventing means body 8a after the procedure of use is sufficiently mastered, enabling the connection of the shoes.

Title: Photoelectron device and optical fiber
Inventor: HANEDA MAKOTO
IPC: H04B10/07
Filed: 1987-06-18
Abstract: PURPOSE:To couple an optical fiber with a laser diode chip stably and optically for a long period by inserting the optical fiber into a cylindrical positioning fixed body which can deform plastically, calking the positioning fixed body partially, and fixing the tip of the optical fiber. CONSTITUTION:The optical fiber 16 whose tip is to be set facing the projection surface of the laser diode chip 38 is held by the cylindrical positioning fixed body 17 capable of deforming plastically. When the optical fiber is fixed, the tip part of the cylindrical positioning body 17 into which the optical fiber 16 is inserted is calked by being crimped and then fixed by crimping the internal wall of the positioning fixed body 17. Namely, the crimping fixation is performed directly by using neither solder nor resin, so no position shift is caused by the secular material deterioration, etc., of solder or resin. Consequently, when the optical axes of the fiber and laser diode chip are aligned with each other with high accuracy, the optical coupling state does not change and the fixation state which is stable for a long period is obtained.
