Filed: 1982-11-08
Abstract: PURPOSE:To detect the movement direction of an invader, flame, etc., without requiring any reflecting plate by storing the level of an infrared-ray beam which is emitted by a projector and reflected by an article temporarily as a reference threshold level. CONSTITUTION:The pulse from a pulse oscillator 1 is amplified by an amplifier 2 to turn on an infrared LED3 and reflected light from the article is photodetected by a photodetecting element 4 to obtain a photodetecting signal. Only the reflected component of the self-emitted pulses is extracted from the photodetecting signal by a synchronizing circuit 8 and stored temporarily in a storage circuit 9 as a reference level 9a; and part of it is fed back to an amplifier 7 to obtain an AGC voltage for level adjustment. If an invader passes between the projector photodetector and the article, the photodetecting signal varies beyond an upper/lower limit level range to detect the invasion. Further, plural detectors are used to discriminate the movement direction of the invader. Further, robbery, fire, etc., are detected.

Title: Dosage reducing method for boiling water reactor
Inventor: HOSOKAWA HIDEYUKI
IPC: G21D1/00
Filed: 1994-08-19
Abstract: PURPOSE: To suppress the adhesion of a radioactive material to reduce the surface dosage by forming a layer of a metal oxide to which the radioactive material is hardly adhered on the primary cooling water contact part of structural member. CONSTITUTION: The surface of a structural member is finished into a mirror surface by buffing or electrolytic polishing, and a film of a metal oxide having corundum structure is formed on the water contact part most outside surface of the mirror surface. The metal oxide of corundum structure works as an insulating body to extremely reduce the permeability of radioactive ion, and an ion exchange reaction is made difficult to occur. Since the surface is polished into a mirror surface, the oxide film of corundum structure can be formed in the state where the crack of the film accompanying increase in compression stress at the growth of the oxide film is minimized, and the suppressing effect is enhanced.  The adhesion of radioative can be thus suppressed to the surface coming into contact with primary cooling water of a structural member such as the pressure vessel outer piping or pump of a core water recirculating system or core water purifying system, and the surface dosage cart be reduced to reduce the exposure of a worker engaged in maintenance and inspection.

Title: Automatic compressor for empty can
Inventor: SUZUKI YASUO
IPC: B30B9/32
Filed: 1982-11-09
Abstract: PURPOSE:To sort compressed empty cans to magnetic and non-magnetic materials by providing a permanent magnet and a specific knock-out bar to a press plate for crushing tin plates, Al juice cans, etc. which are charged into the machine and are supported horizontally. CONSTITUTION:An empty can 2 charged into a hopper 1 is dropped onto a vertically movable support metal 3 by a magnet solenoid 5. A hydraulic cylinder 6 upon sensing the drop advances a press plate 7. The can 2 is crushed between a receiving plate 12 and the plate 7 and when it is thoroughly crushed, the plate 7 is retreated. If the can 2 is a non-magnetic material can, the can is pushed out by the plate 12 held pressed by a spring 14 and falls onto a discharging chute 15, from which it is stored in a containing box 16. On the other hand, the magnetic can is attracted to a permanent magnet 11 on the front face of the plate 7 and is returned together with the plate 7, but at this time the rear end of a knock-out bar 8 contacts with a frame 10 and therefore the bar 8 projects from the plate 7 against the force of a spring 9, thereby knocking the can off from the magnet and dropping the same onto a discharging chute 17. The dropped can is stored in a containing box 18.
