Title: Analyzing device coupled with liquid chromatograph-mass spectrometer
Inventor: KANBARA HIDEKI
IPC: H01J49/04
Filed: 1984-04-27
Abstract: PURPOSE:To remove much solvent and to provide a longer life with less contamination of an ionizing part by concentrating the eluate from a liquid chromatograph in atmospheric pressure before introducing the same into a mass spectrometer. CONSTITUTION:One or plural pieces of slender wires or belts or grooved belts consisting of metal or high polymer are attached to the top end of an output column 6 of an LC and the eluate 5 from the LC enters a lower column 13 along the surface of said wire, etc. 8. The solvent in the LC evaporates or volatilizes gradually into the carrier gas flowing in the open region 10 thereof from a carrier gas inflow port 11 toward an outflow port 12 by which the solute is concentrated. A valve or the like provided in the port 12 is operated so that the concd. eluate 5 enters efficiently the inside of the column 13. If the device is constituted in such a way, the eluate from the LC can be concentrated and fed online into an MS. Since much of the solvent is removed, the contamination in the ionizing part is practically eliminated and the life is extended.

Title: Apparatus for measuring thickness
Inventor: NAMURA MICHIHIRO
IPC: G01B17/02
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To accurately measure to the innermost side of a tube including a bent part by providing an ultrasonic probe and a magnet in a thickness measuring apparatus body, and effectively bringing the circular arc surface of the body into close contact with the inner periphery of the tube. SOLUTION: When the thickness of a tube 4 is measured from the inside, a tube 6 is held by a hand, a thickness measuring apparatus body 5 is inserted to the measuring position, and set. The body 5 has a permanent magnet 3. The circular arc surface of the body 5 is effectively brought into close contact with the inner periphery of the tube 4. When an ultrasonic wave receiving and transmitting unit 9 is started to oscillate an ultrasonic wave, the wave is transmitted as a transmission pulse from a cable 8 to the ultrasonic probe 1 of the body 5, and the wave is oscillated toward the tube 4. The wave is propagated at a predetermined directing angle in the thickness direction of the tube 4, reflected on the outer periphery of the tube 4, returned to the probe 1 side, partly returned from the probe 1 to the unit 9 as a reflection echo, and received.  Since the body 5 is inserted into the tube 4 via a coiled spring 7 by the tube 4, the thickness can be effectively measured even at the innermost side of the tube 4 or the bent tube 4.

IPC: G02B6/04
Filed: 1981-06-01
Abstract: A substantially continuous method of and apparatus for forming an article suitable for an optical waveguide preform wherein the starting member is continuously removed is disclosed. The preform is formed by providing a starting member or bait and applying the particulate material to the exterior surface of the starting member to form a coating thereon. The coating is longitudinally translated while simultaneously additional particulate material is applied to the coating to form a preform body with the preform body thereafter being longitudinally translated. While longitudinally translating the preform body and applying additional particulate material to the end thereof, the starting member is continuously removed from the preform body leaving a longitudinal aperture remaining in the preform body. The particulate material may be applied by one or more burners, the output of which may be controlled to provide a predetermined desired cross sectional composition variation of the resulting preform body. The so formed preformed body may thereafter be suitably heated, consolidated, and drawn into an optical waveguide.

Title: Method for driving motor by inverter control
Inventor: YUASA HIDEAKI
IPC: H02P27/06
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent an inverter from failing and to securely obtain a starting torque by driving a motor based on a frequency and a voltage based on a specific polygonal line pattern of frequency and voltage in starting and linearly decreasing the voltage in deceleration stop. SOLUTION: A control method can be applied by outputting a voltage and a frequency following the V/f pattern of a polygonal line V/f control without limiting to V/f control. Then, when the polygonal line V/f control is used for driving a pump requiring a high starting torque, a high starting torque can be obtained by setting a polygonal line voltage V2 and a polygonal line frequency f2 by the polygonal line V/f pattern. However, in the deceleration stop, a load rate rapidly decreases and reaches nearly unloaded state once being started even in the case of highly viscous fluid, so that an inverter output voltage is decreased linearly, thus securing a large starting torque and at the same time preventing an overcurrent and an abnormal load failure from occurring in the deceleration stop.

CONSTITUTION:A channel protective layer area 14 is formed on a gate electrode 2 provided on an active layer area 13 so that the area 14 has the same width as the electrode 2 has. Then a source electrode section 15 and drain electrode section 16 composed of a metal silicide are connected to both outer walls of the thick part of the active layer area 13. Since the electrodes 15 and 16 are formed just outside of the gate electrode 2 on the electrode 2, the source and drain electrodes 15 and 16 do not overlap the electrode 2 and the overlapping capacitance Cgd between the gate electrode and drain electrode can be reduced.
