Title: Fiber type optical amplifier
Inventor: MIYAZAKI MAYUMI
IPC: H04B10/07
Filed: 1991-06-12
Abstract: PURPOSE:To control exciting lights of a plurality of exciting light sources and to maintain a level of an output signal light of an optical fiber constant. CONSTITUTION:After exciting output lights of exciting light sources 2, 3 are input to an optical fiber 1 and an input signal light from a signal light input terminal 6a is amplified by the fiber 1, part of it is branched, photoelectrically converted, and then compared with a reference current by an error signal output circuit 14. An error signal of its comparison result is branched by an error signal branching circuit 15, and applied to exciting light source output control circuits 10, 11. Thus, the circuits 10, 11 are so negatively fed back by exciting output signals photoelectrically converted from the sources 2, 3 and the error signal that the levels of the output signal lights of the optical fibers become constant.

Title: Recording and reproducing device
Inventor: YONEDA FUKUO
IPC: G11B17/32
Filed: 1988-07-07
Abstract: PURPOSE:To stablize the recording and reproducing of information with a magnetic head integrated in a negative pressure slider by causing the inclination of the negative pressure slider to be larger in an outer peripheral side rather than the inner peripheral side of a recording medium. CONSTITUTION:A negative pressure slider 3 is fit through a conversion supporting stand 4 to a mobile stand 5 so as to be brought into contact with a disk 1. This conversion supporting stand 4 is inclined in advance and can be moved in the radius direction of the disk 1 by the mobile stand 5 which loads this stand 4. On the other hand, a sliding board 8 is provided on the flowout edge side of the disk 1 in the mobile stand 5 and slided with a press guiding rod 7 which is inclined so as to be high when it is moved in the inner peripheral side of the disk 1. Accordingly, when the mobile stand 5 is moved from the outer peripheral side of the disk 1 to the inner peripheral side, as the stand is moved, the inclination of the mobile stand 5 is changed and the inclination of the loaded negative pressure slider 3 is also changed. Thus, the contact between the negative pressure slider and disk is made stable and the recording and reproducing of the information by the magnetic head, which is integrated in the negative pressure slider, can be stablized.

Title: Processing method for copper circuit of circuit board for inner layer
Inventor: SAGARA TAKASHI
IPC: H05K3/38
Filed: 1990-06-26
Abstract: PURPOSE:To uniformly finish reduction of copper oxide by first oxidizing a copper circuit by a wet type to reduce the oxide and then oxidizing by a dry type. CONSTITUTION:The surface of a copper circuit of a circuit board for an inner layer is oxidized by a method of two stages for oxidizing by a wet type and then oxidizing by a dry type. The wet type oxidizing can be conducted by processing the circuit by using aqueous alkaline solution containing oxidizer such as aqueous alkaline solution containing potassium persulfate, aqueous alkaline solution containing sodium chlorite. The dry type oxidizing can be conducted by heating the circuit at a high temperature in the air. Thus, the copper oxide can be formed on the circuit by oxidizing, and when oxidizing by the wet type, a finely acicular uneven part is generated on the oxide to increase its specific surface area. The adherence of the circuit with the resin in the case of secondary molding with the rough surface of the uneven part can be enhanced.

Title: Stacking connector and its manufacture
Inventor: NAGASE KAZUHISA
IPC: H01R13/03
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To mold connectors different in contact pitch by the use of an single metallic molding tool by coating a connector main body with conductive coating material with a nozzle moved traversely, and thereby forming a conductive film thereon. SOLUTION: The first conductive film 3 of a male connector main body 1 consists of a contact 3a acting as a conductive film formed over the swelling 7 of each web plate 5, and of a connecting terminal 3b acting as a conductive film formed over the surface of a base 1a. On the other hand, in a female connector main body 2, a contact 4a on the inner side of each web plate 6 and each connecting terminal 4b over a base 2a, are formed out of a second conductive film 4. The conductive films can be formed at given intervals by means of a nozzle out of which coating material is injected. For example, in the case of the conductive film 3, coating material is applied while the nozzle is being moved from the tip end of each web plate 5 over to the base 1a. After coating has been over, the connector main body 1 is fed by one pitch so as to allow the following conductive film to be formed then.  Therefore, even a male and a female connector formed out of an single metallic molding tool, can be made different in contact pitch.

IPC: B60K5/12
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a simple structural vibration damping device by which a spring constant in a high frequency zone is reduced, and in which an occupied space is not increased, by forming a dynamic damper of a damper elastic body fixed on the inner circumference of the cylindrical body of an inside member and a mass body fixed in the damper elastic body. SOLUTION: A damper elastic body 25 is fixed in a flange 30, and a mass member 72 is embedded in the approximately center of the damper elastic body 25. Then, a dynamic damper 27 is formed by making this damper elastic body 25 and the mass member 72 to serve as a spring element and a damper element, and a mass body, respectively. When vibration transmitted to an elastic body 24 is vibration in a high frequency zone, vibration is controlled by the dynamic damper 27. Therefore, the dynamic spring constant of the elastic body 24 may not be suddenly increased until it exceeds the resonance frequency of the dynamic damper 27. Hereby, a simple structural vibration damping device can be obtained, by which the spring constant in the high frequency zone can be reduced, and in which an occupied space may not be increased.

IPC: H01L41/09
Filed: 1985-07-31
Abstract: PURPOSE:To obtain a high stable torque of long life by radially moving the surface of a stator frictionally contacted with the contacting surface of a rotor. CONSTITUTION:A stator S is formed of a piezoelectric element 2 and an elastic unit 1, a ring-shaped rotor 3 is contacted under pressure with the unit 1 to contruct a surface wave motor. In this case, the rotor 3 is composed in a ring of constant width so that the center O' is displaced to the center O of the stator S, and the rotor 3 is rotated with the center O of the stator S as the center of rotation. Thus, when the rotor 3 rotates on the stator S, it is fluctuat ed in an arbitrary eccentric amount delta to the stator S. Thus, since the contacting surface of the rotor 3 moves momently on the surface 1a of the stator S, the entire surface 1a of the stator S can be efficiently used, and the wear of only one position can be eliminated.
