Abstract: PURPOSE:To allow the safe attracting and fixing of parts, such as optical elements, which are liable to generate failures and strains, the fixing of parts, such as microoptical elements, without pressurizing these parts and the disposition thereof in proximity to other parts by freely attachably and detachably providing a small parts fixing base having an attraction surface and suction hole for attracting the small parts on a fixing base supporting device to which a negative pressure is transmitted. CONSTITUTION:This device is constituted of a negative pressure generator 12, the cylindrical fixing base supporting device 16 having a negative pressure passage 14 at the center and the optical parts fixing base 24 internally having a hollow part 18 and having the optical parts attraction surface 20 and suction hole 22. The optical parts fixing base 24 is used for attracting and fixing the optical parts which are plane on the surface to be attracted, for example, semiconductor lasers 36 of a chip carrier type, etc. The attraction of the optical parts is executed by pinching the optical parts by means of, for example, pincettes, sucking the optical parts into the suction hole 22 where the negative pressure from the negative pressure generator 12 acts and attracting and fixing the optical parts to the optical parts attraction surface 20. Since the optical parts are attracted to the optical parts attraction surface 20 by the negative pressure, the generation of the failure or distortion in these optical parts by the application of an excess pressure is obviated.

Filed: 1990-09-28
Abstract: PURPOSE:To eliminate the possibility of breakage of wire or inferior insulation by delivering an output from a control amplifier for controlling a finger part drive actuator, to the latter by way of a cushion circuit. CONSTITUTION:The opening and closing condition of an actuator 20 is monitored by a speed or position detecting means 22, the actuator is driven with a light force by a control means 24 for the actuator 20 until a finger part 3 clamps a wire W. After a detecting means 22 detects the clamping of the wire W by the finger part 3, the drive force of the actuator 20 is gradually increased up to a final wire clamping force in accordance with a detection signal from the detecting means 22. As a result, the wire W clamped by the finger part 3 is gradually pulled with no an abrupt tension being exerted thereto, thereby it is possible to eliminate such a disadvantage that the wire W wedges into a head edge.

Title: Semiconductor laser
Inventor: IIO SHINJI
IPC: H01S5/00
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To reduce the cost and stable the wavelength for a long time by approximately equalizing the thermal expansion coefficient of a laser chip to that of a chip fixing member to avoid causing a stress strain due to the thermal expansion difference. SOLUTION: A laser chip 1 is fixed to a heat sink block 10 which is then fixed to a stem 11 made of a CuW having a known relation between the thermal expansion coefficient and compsn. i.e., its thermal expansion coefficient agrees with that of GaAs, the main material of the chip 1, when the Cu to W wt.% ratio is 10:90. By equalizing the thermal expansion coefficient of the heat sink block 10 to that of the chip 1, no stress stain occurs by fixing, thus keeping an accurate oscillation wavelength with a simple structure. The block 10 may be cut from a GaAs wafer, without using the thermal expansion coefficient- adjusted CuW.

Abstract: PURPOSE: To improve the dielectric breakdown strength of an insulator creep surface and consequently the reliability of a device by forming different-level cavities, adjoining at a given clearance on the peripheral surface of an insulator, on a portion contacting the insulator of a lower electric potential conductor. CONSTITUTION: When a high voltage is applied between high and low potential conductors 1 and 2a, a triple junction 6, which is the junction part of the low potential conductor 2a, an insulator 3, and a vacuum 4 region, is hidden in the clearance x part in the stepped cavity of the low potential conductor 2a to shield the electric field. This decreases the electric field strength in the triple junction 6 part to increase the dielectric breakdown strength of the insulator 3 by the share. Consequently, when the same potential difference is given, the interval between the high and low potential conductors can be reduced.
