Title: Preparation of tib2 powder
Inventor: IYORI YUUSUKE
IPC: C01B35/04
Filed: 1982-09-29
Abstract: PURPOSE:To prepare TiB2 powder having uniform particle size and low impurity content, by heating TiH2 powder in a plasma generated by applying electrical energy to a boron-containing gas. CONSTITUTION:TiH2 powder is put into a quartz boat, etc., and inserted into a vacuum furnace. A B-containing mixed gas, e.g. a mixture of H2 and BCl3, is introduced into the furnace at 0.1-20 Torr, and heated at >=800 deg.C and at the same time, electrical energy such as high-frequency electrical energy is applied externally to the gas to form the gas plasma. The TiH2 powder is maintained in the atmosphere for a definite time interval and cooled. TiB2 powder having an average particle diameter of about <=2mum, uniform particle size, and low impurity content can be prepared by this process.

Title: Production of fiber
Inventor: KITAOKA KENJI
IPC: C04B35/622
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a uniform, dense and highly pure metal oxide fiber without forming impurities such as sediments in a manufacturing process and to obtain a highly integrated optical modulator using the metal oxide fiber. SOLUTION: This fiber is obtained through the following four processes: the first process in which a raw material containing a hydrate of a metal or a metallic compound is dispersed in an alcoholic solvent having a boiling point of 70 deg.C or higher to prepare a sol solution; the second process in which the sol solution is heated at a temperature not higher than 100 deg.C to polymerize the raw material and make a complex, and thereafter the resultant sol solution is further condensed until it shows spinnability; the third process, in which the treated sol solution is drawn to a gelled precursor of fiber; and the fourth process, in which the precursor of fiber is heated to make a fiber.  Further, an optical modulator to be formed using the fiber has the following structure; plural strings of the fiber 2 are arranged in a almost parallel state on a substrate 4 having V-shaped grooves 5 on the surface; and electric poles 1, 3 are placed on each fiber 2 in a state to be in contact with it so that electric field can be applied on each fiber to change electric property independently.

Title: Method for inspecting defect of glass bottle
Inventor: ITO SHINICHI
IPC: G01N21/90
Filed: 1984-08-16
Abstract: PURPOSE:To prevent the wrong decision of the titled method by measuring continued time of reflected light reflected from the defect of the surface of a glass bottle and discrimination badness only in case the reflected light continues more than the prescribed time. CONSTITUTION:The title is formed of a photoelectric photodetector 1 photodetecting the reflected light reflected from the defect of the surface of the glass bottle rotating at a constant speed, an amplifier 2 amplifying its output waveform and a comparator 4 comparing amplified output with the threshold voltage generated by a threshold voltage generator 3 and making a comparison between two values. A timer 5 is connected with such well known detectors and when the reflected light is photodetected by the photodetector 1, the timer 5 is operated to measure the continued time of the reflected light and a badness signal is outputted only when the reflected light continues, for instance, for >=9msec. Thus, it is prevented that the glass bottle having only foam or a seam line is decided to be the bad bottle by mistake.

Filed: 1990-06-27
Abstract: PURPOSE:To replace a picture without deviating a center of the picture to be replaced by designating a point almost in a center of a range of an object picture to be replaced when one object picture is replaced into other object picture. CONSTITUTION:At first a carriage is moved UP to a point P0(x0, y0) to read an area A. Then a same area whose range is designated with points P1(x1, y1) and P2(x2, y2) is scanned to read a picture and the position of the scanning is calculated so that the point P0 comes in the center of the area of the picture. Then the read picture data is fetched in a RAM. Then an area B is read. At first, the carriage is moved up to the point P1 and the picture is read by scanning the area indicated by the points P1, P2 and the result is stored in the RAM. In the replacement mode, when the area A is required, the picture is read from the RAM and the picture is replaced. When the replacement of the areas A, B is required for the both, the operation above is repeated till the reading of both the areas is finished.

Title: Semiconductor ic package
Inventor: YAMAGIWA AKIRA
IPC: H01L23/10
Filed: 1983-09-19
Abstract: PURPOSE:To reduce the static capacitance of a conductor pattern by a method wherein an insulating material layer having a smaller dielectric constant than a sealing material is interposed between the pattern and the sealing material. CONSTITUTION:The conductor pattern 12 is formed over the first insulation substrate 11 made of ceramic by the vapor deposition method or sputtering method. With respect to the upper cap sealing section, an insulation layer 15 made of ceramic is formed by the film-forming technique so as to cover the pattern 12. After the connection of the semiconductor IC is completed, the second insulation substrate 14 of ceramic the upper cap is welded to the first substrate 11 with the sealing material 13 (low melting point glass). Thus, the pattern 12 is isolated from the sealing material 13 by means of the insulation layer 15 of ceramic having a much smaller dielectric constant than the material 13, i.e., low melting point glass; therefore the static capacitance of the pattern 12 with each other largely decreases.

Filed: 1988-07-08
Abstract: PURPOSE:To enhance the luminous intensity of the central part of a luminous region and to contrive the improvement of an optical coupling efficiency to an optical fiber by a method wherein the region is isolated by concentric circle- shaped grooves. CONSTITUTION:A luminous region 1 is isolated by concentric circle-shaped grooves.

A resin of the optical hardening type may be used so that hardening will occur immediately after it is drawn. Next, after the optical hardening type resin is dripped in the desired region including the chip mount part, resin seal is performed by exposure hardening.

Title: Protective device against commutation failure
Inventor: ROKUTAN HIDEAKI
IPC: H02P7/29
Filed: 1981-10-30
Abstract: PURPOSE:To prevent a battery voltage drop from causing erroneous detection of commutation failures by a method wherein currents in a chopper circuit are detected and signals representing the currents are used to put a commutation failure detecting circuit into operation, when a chopper circuit is made use of for the purpose of controlling a motor. CONSTITUTION:A chopper circuit 8 is used for the driving of a propelling motor 6 aboard a forklift truck or the like. A circuit detecting currents in the propelling motor 6 by means of a detector 7 and detecting circuit 23 for the controlling of a transistor TR3, is added to a stage preceding a commutation failure detecting circuit 19. A normal commutation causes a low potential output from the detecting circuit 23 to turn off the transistor TR3, while a commutation failure turns it on for the effectuation of protection against the failure. Accordingly, erroneous operations under lowered battery voltages can be prevented, it being so set that the absence of trigger signals and motor currents indicate no commutation failure and that there be no need for a protective operation under such conditions.
