Title: Semiconductor light emitting device
Inventor: HASEGAWA KAZUYOSHI
IPC: H01L31/12
Filed: 1988-03-26
Abstract: PURPOSE:To enable the easy wire bonding, and prevent the invasion of noise due to monitor light, by providing the end-portion of a photo detector on the opposite side of a light emitting element, with a protrusion higher than or equal to the height of the light emitting element, and bonding a gold wire from the surface electrode of a light emitting element of multi-light emitting-point array type, to an electrode pattern formed on the protrusion surface via an insulating layer. CONSTITUTION:A light emitting element 1 of multi-light-emitting-point array type is laminated and joined on a photo detector 2 unified in a body with a stress-relaxation member. Current flows through the photo detector 2 and the gold wire 7, and lights 4 and 5 are emitted from a front end surface and a rear end surface, respectively. The emitted light 5 from the rear end surface is received as a monitor light by a light receiving surface 3 of the photo detector 2, and utilized as an optical signal to an APC circuit for output adjustment of the emitted light 4 from the front end surface. In order to drive independently the light emission from each light emitting point of the light emitting element 1, surface electrodes 6 whose number is equal to the number of the light emitting points are formed on the upper surface of the light emitting element 1. As a result, a gold wire 7 is bonded to each of the surface electrodes 6. Since the monitor light reflecting surface 11 of a protrusion 8 is inclined to the light receiving surface 3 at a suitable obtuse angle, reflected light 12 does not interfere with the emitted light 4. Since the height of the protrusion 8 is higher than the light emitting element 1, the interference of the monitor light 5 is prevented by the gold wires 7.

IPC: G21F9/24
Filed: 1986-03-28
Abstract: The present invention relates to a method of excavating a storage complex in rock for storing radioactive material, or other harmful material. The complex to which the method relates comprises a-hollow body which is formed from a solid material and the interior of which constitutes a storage space for the radioactive material or other harmful material to be stored. The hollow body is located in an inner cavity (4) which is excavated from the rock and which has larger dimensions than the hollow body. The hollow body is spaced from the outer walls of the inner cavity (4) such as to leave a space which is filled with an elastoplastic, deformable material. At least one vertical shaft (2) is driven partially through the location of the space (4), and the space is excavated from the bottom of the shaft (2) and upwards, while filling the space or cavity (4) thus formed substantially at the same time as the cavity is formed.

Filed: 1989-03-24
Abstract: PURPOSE:To avoid danger that a magnetic head occurs malfunction based on an unerased RF synchronizing signal to be generated in the case of overwrite recording by controlling it based on the class of a recording track scanned by the magnetic head whether the RF synchronizing signal is fetched or not. CONSTITUTION:The arrangement of pilot signal patterns for tracking control patterns ATF1 and ATF2 to be formed on a magnetic tape is determined respectively concerning recording tracks TA1, TB1, TA2 and TB2.

Title: Formation method for metal film and wiring
Inventor: YAGI HAJIME
IPC: C23C16/34
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To selectively form a metal film without a patterning operation by an etching operation by a method wherein the metal film is formed, by a catalyst CVD method, on the surface of a substrate layer which is exposed inside an opening part in a mask. SOLUTION: A mask 3 which comprises a desired opening part 2 is formed. After that, a Ti film 4 and a TiN film 5 are deposited in this order by a catalyst CVD method using hydrogen on the surface of a silicon substrate 1, which is exposed inside the opening part 2. That is to say, hydrogen atoms which are heated by a catalyst substance so as to be activated etch a silicon oxide film. As a result, a spontaneous oxide film which is formed on the surface of the silicon substrate 1 is etched and removed from the surface of the silicon substrate 1 inside the opening part 2 in the mask 3. The Ti film is deposited on the surface of the exposed substrate 1. In addition, since the activated hydrogen atoms etch the surface of the mask 3, the Ti film is not deposited on the surface in a certain time. As a result, the Ti film 4 is formed selectively on the surface of the silicon substrate 1.
