Title: Optical multiplexer/demultiplexer
Inventor: MORIMOTO YUKIHIRO
IPC: G02B6/28
Filed: 1986-07-25
Abstract: PURPOSE:To simplify the manufacturing process, and to shorten the manufacturing time by forming an optical fiber installing groove and an optical filter installing groove in an optical waveguide on a substrate, and installing and fixing an optical fiber and an optical filter. CONSTITUTION:Each optical fiber 1a, 1b and 1c, or an optical filter 2 is installed and fixed to each optical fiber installing groove 9a, 9b and 9c, and an optical filter installing grove 10, respectively. For instance, the optical filter 2 which has been installed and fixed has a spectral characteristic for allowing a light beam of a wavelength lambda1 to transmit through, and reflecting a light beam of a wavelength lambda2, and when the light beam of the wavelength lambda1 and the light beam of the wavelength lambda2 are propagated, the light beams transmit through the optical filter 2 and made incident on the optical fiber 1b. On the other hand, the light beam of the wavelength lambda2 is reflected by the optical filter 2 and made incident on the optical fiber 1c. In this way, the light beam of the wavelength lambda1 and the light beam of the wavelength lambda2, which have been propagated through the optical fiber 1a are allowed to branch to the optical fiber 1b or the optical fiber 1c, respectively.

Title: Carbon material for nonaqueous solvent secondary battery negative electrode
Inventor: FUJIURA TAKATSUGU
IPC: H01M4/583
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a carbon material for a nonaqueous solvent secondary battery negative electrode with high capacity and excellent charging/discharging cycle characteristics by carbonizing a carbon precursor having specified physical properties, obtained by heat treating pitch in the specified condition. SOLUTION: Pitch is heat treated under a non-oxidizing atmosphere to obtain a carbon precursor having an atomic ratio of hydrogen to carbon of 0.42 or less. The carbon precursor is carbonized in inert gas atmosphere at about 900 deg.C or higher, or graphitized by further heating at 2000 deg.C or higher. As the pitch used, meso-phase pitch having carbon yield of about 70% or more, a softening point of about 170 deg.C or higher, and an optical anisotropy phase content of about 70% or more is preferable. The production condition is selected so that the particle size of the final carbon material has an average particle size of 1-50μm or so, usually of 2-30μm. Since the carbon material is not melt-bonded between particles, drop in characteristics caused by oxidation of broken surface produced by breaking of primary particles is avoided.

Abstract: PURPOSE:To reduce the number of words in a specific expression recognized as unknown words to improve the analysis precision by retrieving a dictionary with an expression as the retrieval key in the case of morpheme analysis which divides a character string consisting of at least two or more kinds of expression into word units and recognizing unknown words of the character string in the specific expression even at the time of failure of retrieval. CONSTITUTION:A KATAKANA(square form of Japanese syllabary) word recognizing part 8 converts the KATAKANA string detected by a KATAKANA string detecting part 7 to a HIRAGANA(cursive form of Japanese syllabary) string by a HIRAGANA conversion part 9. This HIRAGANA string is regarded as reading information of the KATAKANA string and is used as the retrieval key to retrieve word dictionary parts 2 and 11 by a reading retrieval part 10. When a word is found by retrieval, a KATAKANA word recognizing part 8 recognizes the word in a text string.

Title: Method for processing circuit board and method for recycling the same
Inventor: ONISHI HIROSHI
IPC: B09B5/00
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To enable recycling as an electronic component, by grinding a circuit board in the direction of thickness from the side where a connection terminal is protruding, then separating a part of an electronic component from the circuit board, and separating a part of the connection terminal, a copper foil and solder as mixed powder. SOLUTION: By using a grinder 10 rotating in the direction of an arrow, a circuit board 1 is ground following a rightward arrow from the side where a connection terminal 5 is protruding. At this point, a copper foil 2 and solder 3 are recovered as powder 11 together with a resist and constituent materials of the circuit board 1. By grinding the side of the connection terminal, a part of an electronic component 4 having the solder 3 removed therefrom is separated at the same time from the circuit board 1 in a being thrown out. Thus, reuse of the electronic component can be promoted by separating a part of the electronic component from the circuit board. Also, even when the electronic component cannot be reused as a component, recycling of a material from the electronic component is facilitated by winnowing the electronic component according its type.

Filed: 1993-07-15
Abstract: PURPOSE:To prevent the generation of malfunction in sneak path detection oscillation preventing control by measuring a receiving signal in each radio channel, and regarding the receiving signal as burst-like level variation when the level of the receiving signal is suddenly changed. CONSTITUTION:This radio repeater system is provided with a sampling circuit 9 as a sampling and measuring means for sampling a receiving output from a receiving antenna 1 at a fixed interval and measuring its signal level.

For instance, the sampling speed is assumed as 1000 samples per second. The circuit 10 detects a signal level in each sampling. A controller 7 compares the level of each sample with that of its preceding sample, and when their level difference exceeds a previously determined regulated value, the generation of burst-like level variation is judged and control is executed so that repeating gain is not reduced.

Title: Reagent for immunoassay
Inventor: IMAI KAZUNARI
IPC: C07K19/00
Filed: 1981-11-04
Abstract: PURPOSE:To improve solubility to aq. solns. of neutral regions and sensitivity of immunoassay by binding a compd. having a dissociating group or polar group  to an antibody and changing the isoelectric point of the antibody. CONSTITUTION:Diazonium benzenensulfonate is easily obtained by diazotization of sulfanilic acid. When unreacted matter is removed by dialysis and an isoelectric point is measured by using a primary electrophoresis method, 6-7 PI before the reaction changes to about 5 PI after the reaction. The solubility near neutral pH is improved as well. A marking reagent is prepd. by using this chemical conversion method. Luminol is used for the marked compd. and alubmin as its carrier. When the quantity of the light emitted by the luminol is compared between the case in which amino groups are protected by the diazotized sulfanilic acid against antihuman IgG and the case in which no protection is given, the former exhibits intensity of light emission/1% protein= 800, while the latter exhibits 44.5, whereby the marked antibody of high solubility and high intensity of light emission is obtained.
