Title: Optical semiconductor device
Inventor: YOSHIKAWA TOSHIBUMI
IPC: H01L31/10
Filed: 1978-07-24
Abstract: PURPOSE: To obtain an optical semiconductor device keeping a correlation between the conducted output and the wavelength of a radiating light linear extensively through a structure of PN injections of more than one which are formed to have the depth differentiated in the thickness direction of a semiconductor layer.  
     CONSTITUTION: The first PN junction 5 is formed between a semi-conductor substrate 1 and an N type epitaxial area 2 and at the same time, the second PN junction 6 is also formed between N type epitaxial area 2 and P type area 4. A long wevelength component out of the optical energy radiated through forming the first PN junction 5 at a relatively deep position of the semiconductor layer is absorbed to bring forth an electron/positive hole couple, and further a short wavelength component out of the optical energy radiated through forming the second PN junction 6 in an area near the surface of the semiconductor layer is absorbed to bring forth an electron/positive hole couple.

Title: Electromagnetic clutch motor
Inventor: MATSUBAYASHI JIYUN
IPC: H02K7/112
Filed: 1983-05-25
Abstract: PURPOSE:To suppress unbalance vibration by adjusting the unbalance at a rotor unit which is mainly composed of a rotor, a flywheel and the like before it is assembled in a motor. CONSTITUTION:A rotor shaft 19 is extended from an attachment surface of a flywheel 2 to the outside. A stopper 20 is pushed in so as to prevent the flywheel 2 from protruding out. The shape of the rotor shaft 19 outside the stopper 20 is perfectly cylindrical to the center of the shaft. When an external driving force is given by putting a belt around a rotor 1, the same situation as the rotating condition in a motor when this unit is actually assembled in the motor can be reproduced. The balance can be adjusted by treating the outside circumference of the flywheel 2, adding balance weights and working upon balance adjusting bumps 21.

Abstract: PURPOSE:To reduce the number of parts, to make structure simple and to drive a lens with satisfactory responsiveness in respect to a control current by using glassy carbon with fine and uniform structure for a sliding member. CONSTITUTION:The sliding members of soft magnetic materials 4 and 5 at a fixed part are vertically moved while getting contact each other. In coils 6 and 7, a current flows mutually oppositely. These coils are wound so as to surround movable parts 1,2,3 and 5. The glassy carbon is applied also onto the surface of the soft magnetic material part 4 at the fixed part in contact with the sliding member 5 composed of the glassy carbon with the fine and uniform structure.

Title: Cutting device
Inventor: NISHIGAKI HIDEO
IPC: B26D1/38
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To maintain a contact condition under uniform contact pressure by applying the constitution that one of blades as a pair is formed to have smaller thicknesswise deformation resistance against the support means of the blade at both lengthwise ends than at a lengthwise intermediate position. SOLUTION: The flexural deformation amount of both lengthwise ends 3a and 3b of a moving blade 3 coming in contact with both lengthwise ends 2a and 2b of a stationary blade 2 is small, but both lengthwise ends 2a and 2b of the stationary blade 2 have low thicknesswise deformation resistance against a support plate 21. Thus, both lengthwise ends 2a and 2b, when in contact with the moving blade 3, can be deformed so as to escape therefrom. As a result, contact pressure drops, when both lengthwise ends 2a and 2b of the stationary blade 2 come in contact with both lengthwise ends 3a and 3b of the moving blade 3.

Abstract: PURPOSE:To make each part assembleable to the basis part mounted on an auxiliary table at a parts feeding position and shorten its travel distance as well as to aim at the promotion of high efficiency, by installing an auxiliary driving source which drives the auxiliary table attached to a basic driving part in the same direction as the basis driving part. CONSTITUTION:First of all, a single part, serving as a standard, is taken out of the specified parts feeder 21 and mounted on an auxiliary table 18, then a basic driving part 12 and a driving part 13 are driven, making a hand part 14 move up to the specified parts position, and this part is taken out. Next, at the time of assembling this part to that basic part, the basic driving part 12 is not made to move from this position but made to come into a state of being stopped instead, and the hand part 14 is controlled for its position in both Y, Z directions by the driving part 13, while Y directional position control takes place with the auxiliary table 18 driven. And, when parts assembling is over, likewise the hand part 14 is moved to the other parts position by the basic driving part 12 and the driving part 13, and afterward assembling takes place in regular sequence with the same process so that it is no longer reciprocated between the basic part position, thus a travel distance is well shortened.
