Title: Visual sensor
Inventor: NISHIKAWA KOHEI
IPC: B23K9/127
Filed: 1986-07-11
Abstract: PURPOSE:To obtain the visual sensor that an optical cutting plane line picture image does not depend upon the positional relation of the base metals to be welded each other by forming the composition that a projector, an image pickup device and a work head part stand in a line in the visual sensor rotation radial direction. CONSTITUTION:A projector 39 and image pickup device 35 are supported on a sensor bracket and this bracket is linked to a motor via a speed reducer G. It is therefore rotatable by drawing a different turning radius around a torch axis and scans a weld line 9 by being driven with its turning at the profiling motion time. The overlapped weld line 9 corresponds to the break point 10B located on the optical cutting plane line picture image 10 bending hollowly to the light incident direction Z as shown with the arrow mark and the edge of the upper plate base metal 7A corresponds to the break point 10A located on the optical cutting plane line image 10 bending projectively to the light incident direction Z as shown with the arrow mark. This uneven relation has no concern with the rotation speed of a visual sensor.

Title: Mixed-bed desalinator for condensed water
Inventor: SAKAI KIMIO
IPC: B01J47/04
Filed: 1982-09-20
Abstract: PURPOSE:To remarkably reduce the ratio of radioactive dosage in a plant, while enlarging the deironing ability of the titled desalinator for condensed water, in ion-exchange resin, by increasing the ratio of small-size resin particles, and reducing the particle distribution of cation-exchange resin to the possible minimum. CONSTITUTION:Cation- and anion-exchange resins are used as ion-exchange resin to be received in the desalinator for condensed water, and its particle distribution is made above 500 by a screen index (hereinafter referred to as SI). By making SI larger, i.e. increasing the ratio of small-size resin particles, gaps in the resin bed are narrowed to enhance the effect to capture iron clad as fine particles, and the surface area of the entire body of said resin bed is enlarged to enhance the frequency of the collision of said clad against the resin. Thus, the efficiency of adhesion is improved. Moreover, in order to improve the deironing ability of the resin bed while inhibiting the leakage of contaminating cations from it, the particle distribution of the cation-exchange resin is reduced to the possible minimum so as to increase its surface area.

Title: Conduction testing circuit
Inventor: SAKAMOTO TAKESHI
IPC: G01R31/02
Filed: 1982-09-20
Abstract: PURPOSE:To discriminate a coducting state over a wide range, by supplying electric power to emitters of the 1st and the 2nd transistors (TR) through resistances respectively, applying biases to the base connection between the 1st and the 2nd TRs and the base connection between the 3rd and the 4th TRs, and displaying the output between the 1st and the 4th TRs. CONSTITUTION:When a body to be measured is connected to a measurement-A input 21 while a measurement-B input 22 is grounded, the emitter current of a TR12 flows and base currents of TRs 10 and 11 also flow; the collector current of the TR11 flows through a resistance 18 to apply base biases to the TRs 12 and 13, and the collector currents of the TRs 10 and 13 also flow to drive TRs 14 and 15, operating the circuit. As the resistance of the body to be measured is larger, the collector-emitter impedance of the TR10 increases. The load on the TR10 is the TR13 and it is considered that they are reverse; they operate as active loads mutually, so large output variation is led out.

Under that state, the printed wiring board 4 is advanced through a reflow furnace and soldered. The printed wiring board 4 begins to warp thermally in the vertical direction, but the reinforcing dummy parts 5 provided, perpendicularly to the dummy part 7, at the front and rear ends of the board 4 resist the warping motion thus preventing the printed wiring board 4 from being warped vertically.

Abstract: PURPOSE:To remarkably lower the amount of vaporized ultra-low temperature coolant during demagnetization by giving a resistance as a protection resistance during excitation of superconductive coil and setting it to the optimum resistance value for reducing vaporization of ultra-low temperature coolant during demagnetization. CONSTITUTION:For demagnetization of superconductive coil 1, a change-over means 17 is switched to a demagnetization resistance 16 from a protection resistance 13. Next, a switch 7 is closed, a power is supplied to a heater 5 of a permanent current switch 2 and the switch 2 is closed. When the switch 2 is opened, a current of coil 1 is attenuated in accordance with a time constant determined by a combined resistance of superconductive resistance generated and a resistance 16 and the self-inductance of superconductive coil and thereby the coil 1 is demagnetized. In this case, a value of resistance 16 is selected so that the amount of heat including the heat generated by branching loss of switch 2 during demagnetization, heat of heater 5 consumed by opening the switch 2 and heat migrated from a current lead 8 is minimized. Thereby, the amount of vaporized ultra-low temperature coolant 3 during demagnetization can be lowered remarkably without deterioration of function of resistance 13 being excited.
