Title: Reinforcing structure of existing building
Inventor: FUKUSHIMA JUNICHI
IPC: E04G23/02
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To provide sufficient earthquake resistance by a method wherein a carbon fibre reinforcing material is wound around the upper and lower end parts of a column to repair the named parts, an after-placed reinforced concrete-made wall is integrally built through a beam and an anchor beam between the column and the beam, and the column is built without being integrally built. SOLUTION: A carbon fibre reinforcing material 13 is wound around the upper and lower end parts of a PC-made column 10 to effect reinforcement and an after- placed RC-made wall 12 is integrally built through a beam 11 and an anchor bar 14 but built without being built integrally with the column 10. Since the wall 12 is not built integrally with the column 10, a transmission content of a shearing force by the truss effect of a frame comprising the column 10 and the beam 11 is decreased.  Transmission of a shearing force by an arch effect is main and though a shearing force from an arch is locally increased at the upper and lower end parts of the column 10, since the upper and lower end parts are increased in rigidity through winding of the upper and lower end parts with a reinforcing material 13, a high out-of-plane stress is exerted on the column 10 due to an earthquake force, shear fracture is effectively suppressed.

Title: Method for controlling shape of transparent elastic body
Inventor: KAWABATA TAKASHI
IPC: G02B26/00
Filed: 1984-09-25
Abstract: PURPOSE:To control the shape of a transparent elastic body as desired with high accuracy by providing a transparent electrostrictive member provided with transparent electrodes on the surface of the transparent elastic body, impressing a voltage between the electrodes and changing the electrostrictive member. CONSTITUTION:This information corresponding to an impressed voltage 11 is read out by a ROM12 and the information is converted to the impressed voltage by a digital-analog converter D/A13. The impressed voltage is selected by an adder ADD14 and a switch 15 and is outputted from a terminal 16 to the transparent electrodes 5, 6, 7. An oscillator OSC17 changes over the control by the impressed voltage to the detection as a monitor. More specifically, the shape of the electrostrictive member is monitored by the strain-induced electromotive force owing to a change in the shape of said member. The switch 15 is changed over by the output from the oscillator OSC17 which rises to a high level at the specific time and the output voltage owing to the change in the shape of the electrostrictive member with the terminal 16 is amplified in synchronization with the output from the OSC17 by a synchronizing amplifier 18 and the output thereof is compared with the signal output voltage of the desired shape of the output from the D/A13 by a differential amplifier 19. The difference thereof is applied to the ADD14 by which the impressed voltage is changed and the shape of the electrostrictive member 3 is controlled.

Title: Manufacture of semiconductor integrated circuit device
Inventor: YAMANAKA YOJI
IPC: H01L21/027
Filed: 1988-08-10
Abstract: PURPOSE:To enable effective positioning by forming positioning marks in two directions in manufacturing processes different to each other, and then using them as a pair of positioning marks after that. CONSTITUTION:In a MOS type transistor, positioning margins for a contact hole 102 are in the X direction 105 and in the Y direction 106. Since the one which determines the margin in the X direction is a gate electrode position, the superposition mark in the X direction 204 is made of gate electrode material. On the other hand, the margin in the Y direction 106 is already determined with an active region 101, and it has nothing to do with a gate electrode 103, so the superposition mark in the Y direction 106 is so formed that a contact hole formation process 203 may be conformed to the boundary formed by an active region 201. Since the marks are formed each independently in the X and Y directions with materials which attain the real limits to implement the positioning this way, strict superposition margin can be secured, which is effective for cost reduction and yield rate improvement.

Title: Wide band antenna system
Inventor: KATO YASUTARO
IPC: H01Q9/16
Filed: 1990-07-27
Abstract: PURPOSE:To obtain a wide band characteristic by feeding power through an automatic matching device, which matches the impedance of a feeding point automatically over a wide band to a radiating element. CONSTITUTION:The length of an antenna radiating element 3 is set shorter than the 1/2 wavelength of a peak use frequency and enough shorter than the 1/4 wavelength of a bottom use frequency. In this case, the length of feeder lines 4 from an automatic matching device 5 to the respective radiators are made respectively equal. Therefore, feeding power to be supplied to all the radiating elements 3 is almost equally distributed. Namely, by changing the frequency of power to be applied to a device 1, all the impedances/ of the feeding points are changed at the same degree at the respective radiating elements 3. Thus, antenna gain is prevented from being lowered, and the efficient operation is enabled over a wide band.

Abstract: PURPOSE:To manufacture a uniform paint film all over the outside surface of faceplate of a cathode-ray tube by spraying a paint solution out of a spray nozzle portion in such a condition that reversed polarity potentials are given to the faceplate and the spray nozzle portion arranged opposite to the faceplate respectively. CONSTITUTION:A constant voltage is impressed upon the envelope 22 of a spraying device 1 via a DC voltage source 3 while a cathode-ray tube 12 is arranged opposite to the spray nozzle portion 2 of the device 1 above the nozzle portion 2. A high-voltage button 5 in this cathode-ray tube 12 is earthed via an earthing conductor 7, so that a metal-backed film 21 associated electrically with the high-voltage dutton 5 via an inside conductive film 6 may be set in a potential of polarity reverse to that of the nozzle portion 2 of the device 1 by electrostatic induction. When in this condition a paint solution 10 is sprayed out of the nozzle portion 2, each of grains 11 present in the sprayed solution is attracted to the side of a faceplate 4 by electrostatic force so as to adhere to the outside surface of the faceplate 4. Thus, a paint film of specified thickness may be efficiently manufactured all over the outside surface of the faceplate 4.
