Title: Optical package
Inventor: MIYAJIMA HIROE
IPC: G02B6/42
Filed: 1994-04-15
Abstract: PURPOSE:To realize highly accurate low loss optical coupling between a plurality light emitting elements and light receiving elements by interposing an element, e.g. a hologram, for converting the optical path of an optical signal emitted from a light emitting element to the direction of a light receiving element between both elements. CONSTITUTION:An optical integrated circuit 6 and an optical fiber 7 are employed, respectively, as a light receiving element and a light emitting element and a hologram 8 previously provides a diffraction grating forming an optical path for coupling a plurality of objective optical fibers 7 and the light emitting or receiving part of the optical integrated circuit 6 with low loss. When a pentagonal house optical package 1 is employed and the hologram 8 is interposed between the optical fiber 7 and the optical integrated circuit 6, highly accurate low loss optical coupling can be realized through the optical path converting function of the hologram 8 even when optical signals are transmitted between a plurality of optical fibers and the light receiving part of the optical integrated circuit 6.

Title: Digital compression transmitting method of color picture information
Inventor: OGAWA MUTSUO
IPC: H04N1/41
Filed: 1980-06-10
Abstract: PURPOSE:To assuredly keep the compatibility, by carrying out a transmission of picture information other than the white/black one through a combination of codes showing that the run length of the signal received a run length coding is O. CONSTITUTION:A signal compressing circuit 1 is primarily formed with a run  length coding circuit to the facsimile signal of double black and white colors produced by the modified Hoffman system, and detects the change of picture signal B/ WP. Then the subsequent shift pulse SCP is counted by a run length counter 23  and then coded by a ROM24 to be transmitted to the receiver side. For a reception  through a normal facsimile, a decoding circuit has no reaction at all to the signal  whose run length is O and works only with the data of the subsequent run length  equal to n. Thus a red signal is processed as it is in the form of a black or white signal to carry out a picture reproduction.

Filed: 1989-03-31
Abstract: PURPOSE:To facilitate the change of design and the adjustment for moving back a lens and to reduce the number of parts by constituting a camera main body so that three independent parts of the main body are integrally linked. CONSTITUTION:The part of the main body where a spool room is formed, the part of the main body 51 where at least film guiding rail 12 and an image plane forming part 13 are provided and the parts of the main body 52 and 53 where a cartridge room is formed are separately constituted and the respective main body parts are integrally linked.

IPC: G02F1/35
Filed: 1989-03-31
Abstract: PURPOSE:To obtain the optical waveguide consisting of a uniform single crystal of an org. compd. having nonlinearity by packing a soln. dissolved with the prescribed org. compd. into a hollow part to form a core enclosed with a clad, cooling the soln. partially to a supersatd. state to form a seed crystal and further moving the seed crystal in a cooling zone at a specified speed. CONSTITUTION:The soln. prepd. by dissolving the org. compd. which is a nonlinear optical material into a solvent is packed into the space to form the core enclosed by a clad layer and the soln. in the clad layer is cooled partially down to the temp. at which the supersatd. state is attained. This cooled part is moved at the specified speed along the longitudinal direction of the clad layer, by which the seed crystal formed in the initially cooled part is grown along the longitudinal direction of the clad layer. The optical waveguide consisting of the uniform single crystal is obtd. in this way even with the material, such as org. compd. having a large nonlinear optical constant, with which the single crystal is hardly obtainable by a melt solidification system.

Title: Production of silicon single crystal wafer
Inventor: YOKOYAMA TAKASHI
IPC: C30B15/00
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To produce a silicon single crystal wafer for a semiconductor device at a high percent nondefective with respect to oxide film withstand voltage without generating the dislocation cluster by pulling up a silicon ingot with a CZ(Czochralski) method under such conditions that the ratio of (G1 edge)/(G1 center) and the ratio of (inner diameter of OSF (oxidation induced stacking fault)ring)/(single crystal diameter) are controlled so as to be values within specified ranges respectively, wherein each of the G1 center and G1 edge is a temperature gradient defined below. SOLUTION: In this production process, the ratio of (G1 edge)/(G1 center) is controlled so as to be a value within the range represented by the formula I, and the ratio of (inner diameter of OSF ring)/(single crystal diameter) is controlled so as to be a value within the range represented by the formula II, wherein: the G1 center is a temperature gradient ( deg.C/mm) in the axial direction at the center of a single crystal at a temperature in the range of the solid-liquid interface temperature to about 1,350 deg.C; the G1 edge is a temperature gradient ( deg.C/mm) in the axial direction on the periphery of the single crystal at a temperature in the range of the solid-liquid interface temperature to about 1,350 deg.C; and the G2 center is a temperature gradient ( deg.C/mm) in the axial direction at the center of the single crystal at about 1,120 deg.C. In a wafer sliced from the silicon ingot thus produced, by expanding the inner diameter of the OSF ring, the void defect density in a void region existing inside the ring is reduced. Thus, the objective silicon wafer which is appropriately used as a wafer not to be subjected to annealing treatment and also suitable for efficient production, can be produced.

Title: Manufacture of scrap block for steel manufacture
Inventor: NAKAMURA AKINORI
IPC: C22B1/248
Filed: 1981-05-26
Abstract: PURPOSE: To obtain a scrap block for steel manufacture capable of being self- fluxed only by feeding oxygen by mixing scraps of steel products with a specified amount of a carbonaceous solid fuel and compression-molding the mixture.  
     CONSTITUTION: Scraps of steel products are mixed with 5W20wt% carbonaceous solid fuel such as coke, coal or wood chips while maintaining the original shape of the fuel or after suitably crushing the fuel. This mixture is compression- molded to obtain a low grade iron scrap block composed of a scrap part 2 and fuel parts 3. As the internal temp. of a furnace is raised, the fuel 3 in the block is burned to raise the internal temp. of the furnace and to lower the oxidation tendency of air in the furnace. A carburizing and reducing atmosphere is then formed around the fuel 3 at about 800W1,200°C to prevent the oxidation of the scrap part 2. By the carburizing action the m.p. of the scrap is dropped, whereby the meltdown of the scrap is accelerated, and the amount of carbon in molten steel after meltdown is increased.
