Title: Manufacture of semiconductor device
Inventor: MAEKAWA HIROSHI
IPC: H01L21/44
Filed: 1986-05-08
Abstract: PURPOSE:To built a semiconductor light-emitting element free of stress that may otherwise be applied to its light-emitting region by a method wherein an insulating substrate is formed to have prescribed thickness, subjected to necessary manufacturing processes, and then electrodes are built on the substrate and a window layer. CONSTITUTION:On a semi-insulating GaAs substrate 1, a light-trapping layer 2, activation layer 3, and window layer 4 are formed, in that order. The GaAs substrate 1 is subjected to polishing that is performed on its front surface, as the result of which a prescribed thickness (l) is retained. A portion of the GaAs substrate 1 just on a light-emitting region 9 is subjected to etching for the formation of an opening 11. In the opening 11, a titanium-gold-platinum p-type electrode 5 is built. On the surface of the window layer 4, a chromium- gold N-type electrode 6 is built. On the GaAs substrate 1, a gold heat sink 8 is formed. This design prevents stress from being generated in the vicinity of the rear-side P-type electrode 5 attributable to heat produced by a light- emitting element in operation, preventing the light-emitting region 9 from stress that may otherwise be applied thereto and protecting optical output from reduction.

Title: Manufacture of long-fiber reinforced thermoplastic resin composition
Inventor: MURAKAMI HARUFUMI
IPC: B29B11/16
Filed: 1993-04-08
Abstract: PURPOSE:To prevent the direct contacts of a metal and a fiber bundle in a path bent section and prevent the fibers from being damaged during the manufacturing by discharging a molten thermoplastic resin from the first contact side in the upper or lower internal surface of a path at a first contacting position with the apex of the bent section or a section near the apex of the fiber bundle or an upstream position and supplying the contact surface of the fiber bundle with the resin. CONSTITUTION:A fiber bundle to be treated 4 is impregnated with a molten thermoplastic resin during the passage of a path 14 in a crosshead die 6. Said resin is supplied through a feed passage 12, and discharged into the path 14 from discharge openings 16 and 17. The fiber bundle passing in the die 6 is brought into contact with the metal of the die at the apex of the bent section of the path by meandering of a section near to the apex, but said resin is discharged from the first contacting side in the upper or lower internal surface of the path at a position 20, where first contacting is done, or the upstream position to the position 20 in the bent section 18. Accordingly, since a surface brought into with the metal of the die of the fiber bundle 4 is supplied with discharged resin, the molten resin displays lubricating action at the time of a contact with the metal, thus effectively preventing the damage of the fiber bundle.

Title: Apparatus for measuring brightness of light emitting element
Inventor: YOSHINAGA MOTOAKI
IPC: G01J1/04
Filed: 1986-05-12
Abstract: PURPOSE:To systematize an automatic brightness measuring test, by inserting a diffusion filter and an ultraviolet ray pervious filter on the way of the light path from a light emitting element tested to a light receiver in this order so as to be vertical to an optical axis. CONSTITUTION:A predetermined current is made to flow to allow LED11 to light. The light emitted from LED11 is projected to the next diffusion filter 16 and diffused by a frosted glass surface when transmitted through the filter 16. Even if the emitted light from LED11 has a directional characteristic, the brightness of the frosted glass surface becomes almost uniform. Next, the emitted light uniformly diffused passes through an ultraviolet ray pervious filter 17 and only ultraviolet rays of a predetermined wavelength region are uniformly projected to the light receiving surface of a light receiver 12. Because the quantity of the emitted light projected to the light receiving surface is weak, the electric signal resulting from photoelectric conversion by a solar cell 12a is small and successively amplified by an amplifier 12b. The output signal proportional to the brightness of LED11 is guided to a terminal plate 12c to be inputted to the interface of an external computer and a characteristic result is displayed.

Title: Mounting apparatus for mechanical chassis
Inventor: ZANMA SHINJI
IPC: H05K7/14
Filed: 1990-04-25
Abstract: PURPOSE:To effectively damp a vibration simply and at a low cost by a method wherein a vibration-damping material is laid in a part where a mechanical chassis is seated on a main-body frame. CONSTITUTION:A vertical part 6b of a vibration-damping material 6 whose cross section is nearly L-shaped is pushed into a groove 1a-1 in each receiver part 1a; a prescribed edge part at a bent part 2a of a mechanical chassis 2 is seated on a horizontal part 6a. The mechanical chassis 2 is held to a main- body frame 1 by using a mounting metal fitting 8 attached to a boss part 1b by means of a screw 7. In this case, the vibration-damping material 6 converts a vibration energy into a heat energy; it suppresses the resonance amplification of a natural oscillation system, increases the distance attenuation of a vibration propagation and prevents the vibration energy from being accumulated. Thereby, the vibration on the side of the mechanical chassis is absorbed by a characteristic which is inherent in the vibration-damping material 6, and the vibration propagation to the main-body frame can be attenuated sharply.
