Title: Decontamination apparatus for refueling machine of pressure tube reactor
Inventor: TAKAHASHI HIROSHI
IPC: G21C19/19
Filed: 1992-01-16
Abstract: PURPOSE:To perform washing in a pressure container under the state wherein the inner structure of the refueling machine of a pressure tube reactor is attached to the lower head of the pressure container. CONSTITUTION:A decontaminating ring 12a is connected to a high-pressure-water feeding nozzle 16 penetrating a lower head 1 and turned around along the inner surface of the lower head 1. A plurality of jet washing nozzles 12b are arranged in the inner-diameter side of the decontaminating ring 12a. A decontaminating ring nozzle 12 comprises the decontaminating ring 12a and the jet washing nozzles 12b. Under the state, wherein an inter structure 3 is attached, high- pressure water is jetted, and the clad on the surface of the inner structure is washed and removed. Therefore, the exposure dose generated in the disassembling and inspecting works of the refueling machine can be reduced to the value, which is 1/10 or less in comparison with a conventional apparatus.

Inventor: HARA SABURO
IPC: C08J7/00
Filed: 1996-01-20
Abstract: PROBLEM TO BE SOLVED: To improve the surface properties of a synthetic polymer product. SOLUTION: The surface properties (antistatic properties, wettability, dyeability, adsorptivity, antibacterial properties, mildewproofness and sequestering ability) of a synthetic polymer product are improved by irradiating the surface of the product with ultraviolet rays, then applying chitin and chitosan to the surface, and drying the resultant surface to fix both thereon. Since chitin and chitosan are firmly fixed to the surface of a synthetic polymer product, the improved surface properties thus obtained have durability.

Title: Hot-line detachment device
Inventor: SAITO SEIICHI
IPC: G06F3/00
Filed: 1992-02-13
Abstract: PURPOSE:To save the power dissipation by a package to be detached by suspending the supply of clock signals to the electronic circuit of the package to be detached when a detachment mode setting signal is received from the mode setting unit. CONSTITUTION:To a package 1 for which the hot-line detachment is executed, the power is supplied from a 5-V power supply through the power supply connector 3 and the power supply input connector 2. When the change switch 15 of a mode setting unit 14 is turned on, the normal operation mode is set. When the switch is turned off, the detachment mode is set, and then, a signal L is transmitted from a supply controller 12 to the mode setting unit 14. In the supply controller 12, the clock signals transmitted from a clock oscillator 5 through a clock signal line 6 are controlled by a gate 13. Thus, the clock is not transmitted from the supply control circuit 7 to a control line 8. An electronic circuit 9 is detached. Hence, the power is not dissipated. In this way, the power dissipation by the circuit becomes small, and with a simple structure, it becomes possible to prevent the electronic circuit and connectors from being damaged.

Title: Electronic still camera
Inventor: KANEKO KIYOTAKA
IPC: H04N5/335
Filed: 1986-02-12
Abstract: PURPOSE:To substantially include no signal component resulting from the dark current of an image pickup device and to reproduce a still picture of a good picture quality by discharging the dark current immediately before exposing to a solid-state image pickup device and rapidly reading a video signal from the image pickup device after the exposure. CONSTITUTION:When a phase detection signal PG is generated, a system control part 46 counts the progress of this period T2, outputs the first reading signal to a signal processing circuit 20 after the progress and outputs a high speed transfer pulse. Thereby, the signal processing circuit 20 drives the solid-state image pickup device 10 at high speed and discharges a stored charge. When the next signal PG is produced, to a recording part 26, a recording instruction signal is applied only for one unit period from the system control part 46. Therefore, the video signal outputted from the signal processing circuit 20 is modulated only for the period and supplied to a magnetic recording head 30 and recorded on one track of a magnetic disk 32. Thereby, on the one track of the magnetic disk 32, the video signal of one unit is recorded from the position delayed by a prescribed phase T1 from the phase detection signal PG.

At this time, if the sluice valve 9 is opened, the body 1 serves as a valve when the body 1 passes through the liner 2' of the tank A, the water pressure upon the B liner 2 reduces by half and the following body 1 becomes easy to come in the water tank B. Number 4 means a stopper. By the repetition of this operation, the bodies 1, 1... are synchronized with one another, and a power source of a generation plant of no entironmental pollution and no fuel can be obtained.
