Filed: 1994-07-28
Abstract: PURPOSE:To improve the laser oscillation as well as increasing the optical output compared with that in case of no front surface coating step by specifying the reflection factor on the front end face in the photo-etching direction within a large output semiconductor laser. CONSTITUTION:In order to facilitate the cleavage in the chip making step, an n-GaAs substrate 1 side is ground to make a wafer about 100mum thick. Next, an n type electrode 9 comprising AuGe/Ni/Au or Au-Sn/Au is formed by electron beam evaporation on the rear surface of the n-GaAs substrate 1 to be heat-treated for coming into ohmic contact. Later, a solder layer 10 is formed also by the electron beam evaporation etc. Later, end faces are formed into a semiconductor laser chip. At this time, a light emitting end face is formed by dryetching step. Furthermore, for the purpose of protection of the end face and the improvement of the efficiency of the optical output, low refection film in the reflection factor of 5-25% is provided on the front end face while high reflection film in the reflection factor of 90-100% is provided on the other rear end face.

Title: Electronic component mounting device
Inventor: ASAI KOUICHI
IPC: H05K13/04
Filed: 1993-06-23
Abstract: PURPOSE:To provide such an electronic component mounting device that a rotating body can be rotated at a high speed while the rotating body holds nozzle holding bodies holding many component attracting nozzles. CONSTITUTION:An index table 32 rotates around a vertical axis while the table 32 supports twenty component mounting units 40. The nozzle holding body 138 of the component mounting head 130 of each unit 40 rotates around a horizontal axis while the body 138 holds six component attracting nozzles 170 in radial directions perpendicular to the horizontal axis. A nozzle selecting device positions one of the nozzles 170 to an actuating position by turning the nozzles 170. Therefore, the numbers of the nozzle holding bodies 138 and component attracting nozzles 170 can be increased without increasing the diameter of the table 32 and the table 32 and bodies 138 can be rotated at high speeds, because the diameters of the bodies 138 can be reduced for holding the same number of nozzles 170 and the diameter of the table 32 can be reduced for supporting the same number of bodies 138 as compared with the case where the nozzle holding bodies are rotated around vertical axes.

When a state where the transfer paper conveying time is less than the first threshold value and not less than the second threshold value is detected once, the image forming operation is continued.

Title: Automatic optical axis deviation inspecting device for optical head
Inventor: USAMI MASAKI
IPC: G11B7/08
Filed: 1993-06-25
Abstract: PURPOSE:To make inspection of an optical axis of a separate type optical head efficient by automating measurement of an optical axis deviation and decision of normal/ defective condition of its adjustment so as to be rapidly and exactly carried out. CONSTITUTION:When a movable part 2B is moved between both ends of a moving range by supplying a driving current to driving coils 31a and 3lb, a laser beam from a laser light source 21, projecting through an objective lens is received by a photosensor 4, where an intensity signal is successively outputted in proportion to its received light quantity. This intensity signal is processed by a signal processing part 6, where intensity data covering the whole area of the moving range is outputted, and this data is compared with an intensity allowable range by a data processing part 7. When the intensity falls within an allowable range, the adjustment of an optical axis of the incident laser beam on the movable part 2B is decided to be normal, and when it falls outside the allowable range, the adjustment is decided to be defective and 'defect' is displayed on an output unit. The measurement of this optical axis deviation and the decision of normal/defective condition of its adjustment are automatically carried out, and by shortening the moving time of the movable part 2B, the inspection is finished in a short time.

Abstract: PURPOSE:To prevent any water content etc. from permeating into elements as well as absorbing any stress by a method wherein the first inorganic film is formed on a metallic wiring and then polyimide film and the second inorganic film are successively formed. CONSTITUTION:After forming Al wiring layers 2 on a silicon substrate 1, a PSG layer 3 is formed on overall surface; a polyimide film 4 is formed on the PSG layer 3; and after forming a posiresist layer 5 on the polyimide film 4, the posiresist layer 5 on one of the Al wiring layers 2 is exposed to be development-removed. Simultaneously with the development-removal of posiresist layer 5, a part of polyimide film 4 in contact with the removed part of posiresist layer 5 is also removed. Next the residual posiresist layer 5 is removed and then an Si3N4 film 6 is formed by CVD process to be coated with another resist for patterning.
