Title: Device and method of adjusting luminous intensity of laser diode
Inventor: PIITAA TEI FURAWAAZU
IPC: H01S5/0683
Filed: 1992-08-06
Abstract: PURPOSE: To adjust the intensity of a generated light corresponding to an input signal by applying a part of lights emitted from a laser diode as feedback signal to an optical detector, computing an error signal, and generating a voltage control signal through an integrating amplifier, so as to adjust a current flowing in the laser diode. CONSTITUTION: When an optical feedback signal sent through a light path 36 enters a photodiode 10, a current Id is generated by the photodiode, and the current Id becomes proportional to the intensity of the incident feedback signal. The current flowing into a node 5 is the same as that flows out therefrom, and a difference between a current Idac and the current Id becomes an error current Ie . The error current Ie is integrated in a wide frequency band, and the level of the error current Ie shows a difference between the actual intensity of light emitted from the laser diode 32 and acurate intensity shown by Idac . A servo 2 controls the output of a laser diode to keep the error current Ie zero.

Abstract: PURPOSE:To tighten a nut and a spacer simultaneously, by using a center pin as a guide to true up the nut and the spacer and bring them sequentially to the end of a screw shaft to place the spacer around the screw shaft and the nut on its end. CONSTITUTION:A movable holde 1 is moved forth to put a tightener setting section 15 near a screw shaft 28. After that, a center pin 11, a nut pusher 13 and a nut tightener 9 are moved forth in a tubular member 8a so that the center pin is inserted into the holes of a spacer 24 and a nut 10 supported by chucking claws 26a, 26b.

Title: Rotary-motion converter
Inventor: INOUE HIDEO
IPC: H02N15/04
Filed: 1988-08-25
Abstract: PURPOSE:To convert a rotary motion into piston action in a noncontact manner by forming a section having a Meissner effect onto a disk and turning the disk. CONSTITUTION:A rotary motion converter has the center axis 1 of a rotary motion, a body of revolution 2, on the surface of which superconduction is shaped, and a magnetic flux generator 3. Each superconductor 4-11 is arranged onto the surface of the body of revolution 2 centering around the axis l, and the magnetic flux generator 3 capable of being moved in the direction vertical to a surface on the surface of the body of revolution 2 is disposed. Consequently, when some of the superconductors 4-11 arranged onto the surface of the body of revolution 2 are changed into a normal conductive state or the superconductors 4-11 are removed, a Meissner effect disappears in the sections of the superconductors, and force by diamagnetism is not applied to the magnetic flux generator 3. The body of revolution is moved in the approaching direction by previously applying weak force to the magnetic flux generator 3. Accordingly, the rotary motion of the body of revolution 2 can turn said magnetic flux generator 3 into piston action.
