Title: Wide-band optical fiber coupler and production thereof
Inventor: SASAKI HIROYUKI
IPC: G02B6/28
Filed: 1989-09-20
Abstract: PURPOSE:To lower the dependency of the branching ratio on wavelengths by using and stretching the stretched part having different stretching ratios of >=2 pieces of optical fibers having the propagation constant equal to each other. CONSTITUTION:Both of two pieces of the optical fibers having the same propagation constant are previously stretched and in this case, a difference is provided in the propagation constants of both by stretching one thereof longer than the other. Two pieces of the optical fibers formed in such a manner are fused and stretched to form an optical fiber coupler. The period of the dependency of the branching ratio on wavelengths of the optical fiber coupler formed in such a manner is larger than the period of the dependency of the branching ratio on wavelengths of the optical fiber coupler produced by fusing and stretching without previously stretching, by which the optical fiber coupler having the lower dependency of the branching ratio on wavelengths is obtd. The max. value of the branching ratio is made into the value smaller than 100% by the difference in the propagation constants in such a manner, by which the dependency of the branching ratio no wavelengths is lowered.

Title: Rotary disc device
Inventor: TSUKAMOTO ATSUKO
IPC: G11B17/038
Filed: 1983-12-26
Abstract: PURPOSE:To uniform pressing face pressure inflicted by a clamp plate and also to insulate the oscillation from a hub by adopting the soft structure for the part between a circumferential part of a clamp plate fixing a rotary disc and a rigid structure tightened to the hub. CONSTITUTION:The clamp plate 5 applied to the magnetic disc device is constituted of a bolt tightening part 5a tightening the clamp plate 5 to the hub with a bolt, a circumferential ridge part 5b pressed into contact on the magnetic disc 1, and a part 5c of the soft structure formed thinnly for the plate thickness with the disc part between the circumference part 5b and the tightening part 5a. The presence of the part 5c of the soft structure absorbs the vibration from the rotary shaft and the hub so as to insulate the vibration with the disc 1. Since the outside of the tightening part 5a is surrounded by the soft structure, the entire rigid structure is attained so as to press the disc 1 with a uniform force thereby decreasing very less the weaving of ruggedness.

Title: Vibration control structure and vibration control device
Inventor: KATAYAMA ISAO
IPC: F16F15/02
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To effectively perform a damping operation in a compact structure even under straight line reciprocating motion vibration having large amplitude by connecting a vibrator that performs straight line reciprocating motion vibration to a rotary damper through a converting mechanism for converting the straight line reciprocating motion vibration into rotation reciprocating vibration. SOLUTION: A converting mechanism 10 is formed in such a constitution that a rack 17 is attached downward on a joint 7 arranged on lower ends of braces 6, 6 while attaching a pinion 16 on a center part of a longitudinal direction of a rotary shaft 11 in a fixed condition. Straight line reciprocating vibration of a horizontal direction generated by an earthquake is damped by resistance of an impeller 12 and a high viscous material 15 as rotary reciprocating motion vibration transmitted from the joint 7 to the shaft 11 of a rotary damper 9 through the rack 17 and the pinion 16.  In the case where amplitude of horizontal straight line reciprocating motion of a building is large, damping can be effectively performed by executing the rotary reciprocating motion of the rotary shaft 11 with large amplitude, and thereby, it is possible to provide a compact structure without enlarging the rotary damper 9.

Abstract: PURPOSE:To enable parts to be detected accurately by providing a means for reflecting an incidence light with a specific diffusion directivity at an upper part of a part holding nozzle tip and a means for picking up the image of the valid reflection light at the lower part of the nozzle. CONSTITUTION:When a nozzle 12 moves to a specified position, a light source 15 projects light toward a diffusion reflection means 14 which is provided at an upper part of a tip of the nozzle 12. Since the diffusion reflection means 14 reflects light from the light source 5 with the diffusion directivity, an image pick-up means 22 at a lower part of the nozzle 12 receives reflection light like parallel light by a diffusion reflection means 14. At this time, the inclination angle of the diffusion reflection means 14 to the nozzle 12 and the position of the light source 15 with respect to the nozzle 12 are so determined that the light-reception angle beta of the image pick-up means 22 for receiving effective reflected light out of the light diffusedly reflected by the diffusion-reflection means 14 is given by beta=90 deg.C+ or -DELTA/2 (deg), where the diffusion directivity angle of the effective reflected light is DELTA(deg), thus enabling a part which are attracted to the nozzle 12 to be detected accurately.

Title: Optical disk device
Inventor: KONDO MASAMICHI
IPC: G11B7/095
Filed: 1994-10-12
Abstract: PURPOSE: To prevent destruction of the recorded data even when a track excepting a target track is irradiated with a beam, by switching output of a laser resonator to reproducing use when an off-track due to external impact is detected at a recording time. CONSTITUTION: When a shock detection signal, that is, 'H' at the time when the off-track due to the external impact occurs is supplied from a shock detection circuit through a terminal 70 when a signal is recorded, a transistor Tr1 is turned on. Thus, a voltage value of a laser power control signal is lowered to a divided voltage value by resistors R22, R21, and an APC circuit 73 makes laser power of a laser diode LD reproducing power based on that. That is, since the power of the laser diode LD is switched from recording use to the reproducing use when the off-track due to the external impact occurs at the recording time in a laser drive circuit, the destruction of information already written on other track close to the target track is prevented in the optical disk device.
