IPC: A61M5/20
Filed: 1988-11-15
Abstract: PURPOSE:To enable a reduction in the possibility of radiation exposure by introducing a determined amount of radioisotope(RI) solution direct into a diluting vial from a IR generator integrally combined into a device by on-line and measuring its radioactivity. CONSTITUTION:A determined amount of RI solution is sampled into a syringe 32 from a RI generator 30 by the opening and closing of opening and closing valves 36, 37 and the operation of the piston 35 of the syringe 32, then the determined amount of the RI solution is injected into a diluting vial 31. The radioactive strength of this RI solution is measured by a radiation detector. On the other hand, a determined amount of physiological salt solution from a physiological salt solution vessel is sampled into a syringe 40, and then the opening and closing valve 39 is opened to inject the determined amount of the physiological salt solution to the diluting vial 31. Hence, the specific radioactivity can be determined from the amount introduced into the vial 31 and the radioactive strength measured by the radiation detector. As a determined amount of the RI solution can be automatically obtained direct from the RI generator in this way, the possibility of radiation exposure of operators can be reduced.

Title: Manufacture of electrostatic chuck
Inventor: WATABE TOSHIYA
IPC: B23Q3/15
Filed: 1989-11-06
Abstract: PURPOSE:To make it possible to minutely and accurately control volume resistivity by a method wherein firing is performed after titania paste is dispersely printed by screen process printing method on the surface of a ceramic green compact, which turns to be an insulating layer. CONSTITUTION:Titania paste 2 is printed by screen process printing method on the surface of the uppermost layer sheet 1a among ceramic green sheets constituting insulating layer. Material 3, which serves as an inner electrode, such as W paste is printed similarly by screen process printing method on the surface of the uppermost layer sheet 1b among ceramic green sheets constituting base material. Since the amount of the titania paste applied on the surface of the sheet 1a by one operation of screen printing cycle can be made smaller than that by solid printing by the method as just mentioned above, the coating amount of the titania paste can be controlled accurately. A laminate 4 and a terminal part 5, which connects inner electrode and power source, are produced by piling up the ceramic green sheets 1.... After that, the laminate 4 is charged in a firing oven so as to be reductively fired.

Title: Reinforcing structure of bridge
Inventor: KAWAKAMI YOSHIMICHI
IPC: E01D1/00
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To give reinforcement in the direction parallel to and perpendicular with the bridge axis without significant increase of a dead weight rate, and prolong the fatigue life of a bridge by providing reinforcing members consisting of FRP lateral girders and vertical girders on the lower surface side of a floor boards, and then fastening the lateral girders to steel main girders. SOLUTION: A concrete floor board 4 is mounted on a pair of steel main girders 3, 3 extending in the longitudinal direction at both sides. Lateral girders 1-1 of an FRP reinforcing member 1 are joined to the steel main girders 3, 3, by bolts 2, and vertical girders 1-2 of the FRP reinforcing member 1 are arranged and joined by bolts so as to be adjacent to the bottom of the concrete floor board 4 and the lateral girders 1-1 of the FRP reinforcing member 1. Since stress exerting the concrete floor board 4 runs to the steel main girders 3 via the FRP reinforcing member 1 not only from flanges 5, the burden stress of the concrete floor board 4 and flanges 5 on the steel main girder can be reduced, resulting in a prolongation of the bridge.  In addition, use of a lightweight FRP material as a reinforcing member can restrain the weight increase of the bridge due to such reinforcement in minimum, thus lessening attendant work accompanied by increasing of dead weight.

Abstract: PURPOSE:To eliminate useless operation or the continuance of ventilating operation to be carried out even after a satisfactorily ventilated state is available by operating automatically a ventilating fan interlocked with the operation of a lighting switch after having left a room and halting the operation of said ventilating fan in automatic mode after a preset time has lapsed. CONSTITUTION:When it is light indoors during daytime, a photoelectric switch EE is turned off so that electric current may not flow to a relay M2. As a result, a constantly open contact a21 remains under an off-state and a lighting device L will not light up. On the other hand, the constantly open contact b1 of the relay M1 is under an off-state by turning on a switch S, which halts the operation of a ventilating fan F. When having left a room, the switch S is turned off by manipulating the knob of a door so that a constantly open contact a12 of the relay M1 may be kept under an off-state, thereby putting out the lighting device L. On the other hand, a constantly open contact a11 is turned in an off-state, but a timer means T maintains a constantly open contact at under an on-state during preset time. By turning off the switch S, the constantly open contact b1 returns to the off-state so that the ventilating fan may be operated while it may be suspended after the preset time is over.
