Title: Ridge waveguide type semiconductor laser element and its manufacture
Inventor: YATANI MITSUYOSHI
IPC: H01L21/306
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To obtain a ridge waveguide type semiconductor laser element which reduces reactive current, improves laser characteristic and has excellent reliability, and its manufacturing method. SOLUTION: In a ridge waveguide type semiconductor laser element 1, an etching stop layer 6 is constituted of a first region 6A which comes in contact with a ridge part 9, and a second region 6B which comes in contact with a pair of first conductivity type GaAs current constriction layers 10, 10. The resistance value of the second region 6B is higher than that of the first region 6A. The second region 6B is formed by irradiation with ions. Regarding the ridge waveguide type semiconductor laser element, a second conductivity type etching stop layer is constituted of a first region which comes in contact with the ridge part, and a second region which comes in contact with a pair of the first conductivity type current constriction layers. Since the resistance value of the second region is higher than that of the first region, a driving current flows from the ridge part, the first region of the second conductivity type etching stop layer, a first clad layer of second conductivity type to an active layer, so that generation of a reactive current which does not contribute to light emission can be reduced.

IPC: G01B11/24
Filed: 1988-07-11
Abstract: PURPOSE:To accurately measure the shape of a fine part by picking up an image of a measured surface with low magnification and high magnification under the same conditions. CONSTITUTION:The light beam emitted by a laser light source 10 is changed in direction by 90 deg. through a mirror 12 and the made into parallel luminous flux by a beam expander 14 to be made incident on a half-mirror 16. This light beam is changed in direction by 90 deg. and the light is emitted on the surface 18 to be measured and also emitted on a reference surface 20. The reflected light beams from the surface 18 to be measured and reference surface 20 are made incident on a low-magnification image forming lens 26 through a beam splitter 24. Further, the light beam which is reflected by the splitter 24 is made incident on a high-magnification image forming lens 30 as interference light. Further, a camera 28 for low-magnification measurement picks up an image of interference fringes corresponding to the low magnification and sends its image signal to a memory 34. Further, a camera 32 for the high magnification picks up an image of interference fringes corresponding to the high magnification and sends its image signal to a memory 40. Thus, the shape of the fine part is accurately measured.
Patent JP-H1117973-A (JP)
Title: Image processor
Inventor: OKAWA TOMOJI
IPC: H04N1/46
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To exactly judge a character, etc., on a colored original by reducing a necessary image area to be referred to. SOLUTION: Subtle dispersion at a border between colors is corrected by correcting judging signals (binary signals) CN, MN, YN in a correction part. For example, in the case of a color between G and C, C and G are separately generated and the color becomes difficult to be observed when it is judged by every pixel. In addition, a color is sometimes judged erroneously due to deviation of a reading position at the border between a color and a white ground. The correction part is constituted of a threshold correction part 61 and memory 62 and threshold data is inputted as inputted data in the threshold correction part 61. The inputted threshold data is corrected at the threshold correction part 61, outputted and the outputted data similarly becomes inputted data of the memory 62.  Consequently, the dispersion of the color is corrected by using two pieces of data like the data in the memory 62 and the threshold data inputted from the previous stage in the threshold correction part 61.

Title: Manufacture of fiber orientated product of short-fiber mixed rubber
Inventor: YOKOBORI SHIZUO
IPC: F16L11/08
Filed: 1993-07-13
Abstract: PURPOSE:To provide a product, reduced in thermal. expansion at a high tempera ture and prominent in the stability of sizes as well as the retaining property of configuration, by a method wherein the oriented direction of short fibers is arrayed concentrically in the lengthwise direction of the short fibers. CONSTITUTION:Short fibers are arrayed concentrically in the lengthwise direction of the short fibers. In the case of a high-speed rotating high-load rubber roller, for example, when a short fiber mixing rubber is employed and the short fibers 13 are arrayed concentrically in the lengthwise direction of the fibers, strain with respect to the direction of arraying of the short fibers is reduced without cancelling the strain effect with respect to the load since the roller receives a load W vertically with respect to the roller whereby the rupturing force of bonding, applied on the bonding surface between the core metal, is reduced.

IPC: G11B5/64
Filed: 1989-07-06
Abstract: PURPOSE:To obtain excellent corrosion resistance by incorporating specified amts. of Ni and an element selected from Ta, Mo and Nb, and the balance Co into a magnetic layer. CONSTITUTION:The magnetic layer contains 8 - 30 atomic% Ni, one or more elements selected from Ta, Mo and Nb by total 3 - 10 atomic% and the balance Co. By this composition, magnetic characteristics of the layer can be significantly improved.

As for a nonmagnetic substrate to be used, reinforced glass, crystallized glass, aluminum alloy and aluminum can be used. A nonmagnetic metal base layer is formed on the nonmagnetic substrate by using Mo, Bi, etc., and preferably Cr or Ti is used for it. Thereby, the obtd. medium is superior for high-density recording and has excellent corrosion resistance.

Title: Pre-treating method for molten iron
Inventor: AOKI MATSUHIDE
IPC: C21C1/02
Filed: 1986-07-23
Abstract: PURPOSE:To prevent wear of a lance nozzle by covering flux combining slag- making improving material having CaO as main composition on molten iron surface and using the exclusive injection lance in desiliconizing process. CONSTITUTION:In the pre-treatment of desiliconization and dephosphorization in the molten iron, the molten iron is charged into the molten iron pre-treating vessel, and the flux combining the slag-making improving material (Mn ore, etc.) having CaO as main composition is covered on the molten iron surface from the initial stage of pre-treatment. At the time of executing the desiliconization under this condition, the lance for exclusive bubbling stirring is separately prepared and the powdery flux having iron oxide as main composition is injected into the molten iron by carrier gas. At the time of completing the desiliconizing treatment, this injection lance is pulled up and while oxygen source is supplied on the molten iron surface, gas for bubbling is blown from a bottom-blowing nozzle to execute the dephosphorization. In this way, wear of the nozzle for injection lance is prevented and its service life is prolonged and this exchanging frequency is decreased.

The parity bit added to the tail of each block is changed alternately in such a way that, for example, an even parity bit Pe is added to the 1st block and an odd parity bit Po is added to the 2nd block, and then, the even parity block Pe is added to the 3rd block, and so on. Therefore, the maximum continuous number of the same code is suppressed to (3m+1).

Title: Surge protective circuit
Inventor: YANAGASE AKIO
IPC: H02H9/04
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To improve the surge withstanding strength by a method, wherein a surge protective diode is connected between 1st and 2nd power supply voltage supply terminals, and a surge absorbing path through the other circuit is secured. SOLUTION: Surge protective diodes D1a and D2a are connected between external terminals (anodes) and power supply terminals (cathodes). Surge protective diodes D1b-D4b are connected between external terminals (cathodes) and grounding terminals (anodes). The feature which is different from the conventional system is that a protective diode D5 is connected between one power supply terminal 1 (anode) and the other power supply terminal 2 (cathode). If a positive surge pulse is applied to the power supply terminals, a part of a surge current flows directly through an internal circuit and into the ground, without flowing through the protective diode as in the conventional system. The remaining surge current flows through the protective diode D5, connected between the one power supply terminal 1 (anode) and the other power supply terminal 2 (cathode) and into the ground.
