Title: Control device for engine
Inventor: KADOTA TAKASHI
IPC: F16H7/00
Filed: 1985-08-06
Abstract: PURPOSE:To prevent abrasion and breakage of teeth of a timing belt by limiting an increase in output of an engine when the rotation phase difference between a driving gear and a driven gear is a designated value or more to limit the gear skip of the timing belt. CONSTITUTION:A phase difference between a driving gear 33 and a driven gear 39 is detected by a rotation phase difference detecting portion 51a of a control unit. Both gears 33, 39 are connected to each other by a belt 41, and a fixed relationship is kept in the rotation phase difference between the gears, so that when a rotation phase difference exceeding the rotation phase difference is detected, it is judged to be ominous of causing gear skip in the timing belt 41, and a high-level signal S is supplied from the rotation phase difference detecting portion 51a to an engine output limiting portion 51b. On receiving the high level signal S, the engine output limiting portion 51b limits an increase in output of an engine to prevent the occurrence of the gear skip in the timing belt 41.

Title: Method for polishing end face of optical connector for ribbon fiber
Inventor: MURATA OSAMU
IPC: G02B6/36
Filed: 1995-06-15
Abstract: PURPOSE: To project precisely optical fiber parts with few polishing sags by inserting fixedly a press fit pin into a guide pin hole to polish the end faces of the optical fibers. CONSTITUTION: Since a press fit pin 6 has a dummy part 9, polishing pressure is dispersed to adhesives 5 and the dummy part 9 of the press fit pin 6, the polishing pressure is not applied to the end face of an optical connector and polishing sags are hardly caused. Also, since in the subsequent polishing process the press fit pin 6 is shaped to have a conically tapered part 8 pressed into intimate contact with a guide pin inserting hole in the tip part of the optical connector, the press fit pin 6 is held with a wedge effect even if the dummy part 9 is removed by the polishing action in the adhesive removing process. Thus, since the polishing pressure is concentrated to protect a guide pin hole inlet in which the polishing sags are liable to be caused, the polishing sags are hardly caused.

Title: Method and apparatus for recording multiple hologram on recording medium
Inventor: KENESU JII RAIBU
IPC: G03H1/28
Filed: 1987-07-10
Abstract: PURPOSE: To obtain multiple holograms on individual recording media by directing phase-coherent signal light and reference light to respective optical paths, passing the signal light through a gate and generating and converging matrix light on a recording medium through a mask, and controlling the movement of the mask and gate with control signals respectively. CONSTITUTION: The reference light 114 and signal light 116 are generated by dividing the output light 104 of an Ar ion laser. The reference light 114 is directed to the recording medium 132 through an attenuating filter 112 and the mask 130. The signal light 116 is passed through the attenuating filter 142 to pass through the gate 144, spatially modulated by exposure of plural scenes, and made by a multiple-hologram lens 150 into the matrix light 152, which is passed through the mask 130. On the recording medium 132, the passing light interferes with the reference light to form a diffraction pattern. The control signals 160 and 162 are adjusted to move the gate within the movement time of the mask 132, thereby performing the exposure. Consequently, the multiple holograms can be recorded on the individual recording media.
