Title: Method and system for radiation tomographic
Inventor: GONO MAKOTO
IPC: A61B6/03
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of image quality by linearly correcting a radioactive ray detecting signal according to an irradiation position error in a radioactive ray beam in a detecting element array, and reducing weight of the radioactive ray detecting signal having a large residual error after linear correction on radioactive ray detecting signals of plural views. SOLUTION: An X-ray beam 40 having a width and a thickness in one and the other of the mutually vertical two directions vertical to the irradiating direction is irradiated from an X-ray tube 20 so that the X-ray beam 40 is detected by a detector array 24 by arranging plural X-ray detectors 242, 244 in the width direction and the thickness direction of the X-ray beam 40. A tomographic image is formed on the basis of X-ray detecting signals of plural views obtained by rotating this X-ray irradiating/detecting system.  At this time, the X-ray detecting signals are linearly corrected according to an irradiation position error in the X-ray beam in the arranging direction of a detector train to reduce weight of the X-ray detecting signal having a large residual error after lenear correction as well as to increase weight of the X-ray detecting signal of an opposed view of the X-ray detecting signal having a large residual error.

Title: Chlorinated vinyl chloride resin pipe for sprinkler piping
Inventor: TOMITA HIROSHI
IPC: B29K27/06
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To improve thermal resistance and impact resistance by a method wherein chlorinated vinyl chloride resin of which a chlorine content and a polymerization degree are specified, is used. SOLUTION: A chlorine content of chlorinated vinyl chloride resin is 60-70 wt.%, and its mean degree of polymerization is 600-1400. The chlorinated vinyl chloride is, for example, a vinyl chloride homopolymer; a copolymer of vinyl chloride monomer and a polymerisable monomer having unsaturated bond capable of being polymerized with vinyl chloride monomer; a graft copolymer wherein vinyl chloride is graft copolymerized with polymer, etc., and those are independently or by two or more kinds jointly used. Further, as the method for preparing chlorinated vinyl chloride resin, a water suspension chlorination method is industrially preferable.  Further, as a method for adjusting a chlorine content, for example, vinyl chloride resin may be adjusted at a stage of being chlorinated, and chlorinated vinyl chloride resin of high chlorination degree and that of low chlorination degree or ordinary vinyl chloride resin may be adjusted by blending.

Title: Power supply, discharge lamp operating device and illuminating device
Inventor: KITAMURA NORIYUKI
IPC: H02M7/48
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To attain the control which gives an appropriate gain when loaded and not loaded by comparing the detected value of a voltage change between the output terminals of a power circuit with a reference value, and switching the gain of inverter circuit based on whether it is in excess of the reference value or not. SOLUTION: In a control switching circuit 21, R5 , R6 for detecting the value of voltage VDC between output terminals, and a detecting part 22 constituted for a power dividing circuit with a capacitor C5 are provided. When loading, detected voltage is lower than reference voltage VREF, therefore, a transistor Q2 is operated to indicate a resistance value corresponding to the detected voltage. The voltage determined by the power dividing ratio of (a resistor R7 , the resistance value of the transistor Q2 and a resistor R8 ), and a resistor R9 is supplied between the gate and source of a transistor Q1 to give an appropriate gain.  On the other hand, when no-loading, the detected voltage becomes higher than the reference voltage, therefore, the transistor Q2 is turned off, and controlled with fixed voltage determined by the power dividing ratio of the resistors R8 , R9 between the gate of transistor Q1 and the source. It is thus possible to make control appropriately both in loading and no-loading.

Filed: 1990-04-26
Abstract: PURPOSE:To enable simplification of a surface-roughening process of a surface by effecting a spatter etching following a spattering in a spatter device in which a metal film is formed, thereby making the surface rough. CONSTITUTION:Firstly, a high-frequency spatter device which is available for both spattering and spatter etching is used to effect spattering and spatter etching in turn. A predetermined thickness of aluminum film 31 is formed on a surface of a ceramic substrate 30. Successively, the surface 31a of the aluminum film 31 is subjected to spatter etching, thereby making a rough surface whose average roughness of center line Ra is about 0.2mum. Namely, because the spatter etching is effected successively to the spattering by use of the same spatter device, an efficiency is improved. Next, a resist pattern 33 is formed directly on the surface 31b of an Al film 31A and successively, the Al film 31A is removed. At last, the resist pattern 33 is removed to leave a conductor pattern 34.
