Title: Method of chemical decontamination
Inventor: KAWASAKI NOBORU
IPC: G21F9/28
Filed: 1990-07-26
Abstract: PURPOSE:To make it easy to control the density and composition of a decontaminating agent by allowing one part of a decontamination liquid during circulation to pass through a mixed bed type ion exchange resin (demineralizer) so as to remove radioactive nuclides and the decontaminating agent from the decontamination liquid, and injecting a new decontaminating agent in an amount corresponding to that of the decontaminating agent removed. CONSTITUTION:Decontamination and purification are carried out first; i.e., a decontamination liquid is circulated by a recirculation pump 20 for decontamination and also one part of the decontamination liquid is allowed to pass through a demineralizer 34 and radioactive nuclides are removed therefrom and purified water is returned to a steam drum 16. The same amount of decontaminating agent as that of the radioactive nuclides removed when the decontamination liquid is allowed to pass through the demineralizer 34 is continuously injected into a lower header 24 from a chemical injection tank 33 by a chemical injection pump 32 and the density of the decontaminating agent is maintained at a specified value. Next, only decontamination is carried out; i.e., the density of the decontaminating agent is maintained at the specified value and the decontamination liquid is circulated by the pump 20 for decontamination. After decontamination is completed, cooling water is fed to the shell side of a non-regenerative heat exchanger 36 so as to cool the decontamination liquid and also the decontamination liquid is allowed to pass through the demineralizer 34 so as to remove the radioactive nuclides and the decontaminating agent from the decontamination liquid.

Title: Laser marking device
Inventor: ITO HIROSHI
IPC: B23K26/066
Filed: 1987-08-11
Abstract: PURPOSE:To enable marking over a large area with high accuracy by reducing luminous fluxes to increase the energy density of laser light and scanning the laser light to a mask while a work and the mask are held fixed, thereby executing marking. CONSTITUTION:The laser light L outputted intermittently from an oscillator 10 by a control part 18 is condensed in one direction by a 1st optical system 11 and is entered to a plane mirror 16. The mirror 16 is oscillated at the angle corresponding to a pattern 20 and in the direction orthogonal with the longitudinal direction to an elliptical shape to reflect the incident laser light L toward a cylindrical mirror 19. The spots L1-Ln which are respectively made into the parallel luminous fluxes from the laser light L are projected to the mask 21. The laser light past the pattern 20 is condensed by a condenser lens one after another onto the surface of the work 22 so that the image of the pattern 20 is marked on the surface thereof in arbitrary size. The laser light increased in the energy density by a shaping optical system 11 in such a manner is scanned in the form of the parallel luminous fluxes to the mask 21 and, therefore, the fixed state of the mask 21 and the work 22 are maintained and clear marking is executed.

Title: Refrigerator
Inventor: HARA YASUO
IPC: F25D17/08
Filed: 1992-07-01
Abstract: PURPOSE:To promote an automatic defreezing of frozen items when they are stored in the storing box by a method wherein a defreezing promoting mechanism is operated in the case that a temperature decreasing degree within the storing box detected by a temperature sensing means is higher than that of normal cooling operation. CONSTITUTION:As a temperature within a refrigerator is less than a set lower limit temperature, electrical energization for a compressor motor 52a and an air-cooled fan 53 is stopped. However, if temperature of the stored frozen items is sufficiently low, the temperature within the refrigerator is further decreased. Then, as the temperature within the refrigerator is further decreased than a fan starting temperature, a temperature sensor Th3 is electrically energized, so that an exciting coil of a relay R7 is electrically energized and a relay R8 in a self-holding circuit 88 is self held in its ON state. Then, a make contact point R8-2 connected in series with the inter- refrigerator fans 30a and 30b is electrically conducted and then the inter-refrigerator fans 30a and 30b are electrically energized by electrical power supplying passages PW1 and PW2 through this make contact point R8-2. Then, the fan 32 is rotated by fan motors 31 in the inter-refrigerator fans 30a and 30b to circulate air within the chamber RM1 and to promote defreezing operation.

Title: Gate apparatus of printed book feed passage
Inventor: TAKEHARA TORU
IPC: B42C19/08
Filed: 1989-08-02
Abstract: PURPOSE:To make the opening and closing operation of a gate smooth and certain and to prevent the hanging of the front end of a printed book due to the rubbing at the time of gate operation by providing the bearing supporting the gate on the machine body of a feed passage in a freely rotatable manner and a shaking mechanism for allowing the gate to fall in the direction same to the feed direction of the printed book and erecting the same in the reverse direction. CONSTITUTION:The body W fed from the collapsing apparatus of a line by a conveyor is intercepted by the pawls 12 of a gate 1 held to an erected state and stopped in such a state that the front end thereof is in contact with the front surface of the pawls 12. The body W intercepted for a definite period is sent to a lapping apparatus by the falling of the gate. At this time, the operation of a solenoid 33 is transmitted to a shaking shaft 11 through a connection plate 32 and a lever 31 and the pawls 12 of the gate 1 are allowed to fall in the direction same to the feed direction of the body W. Said operation is performed so that the front end of the body follows the pawls 12 of the gate 1 beginning to fall by the feed force of the conveyor and begins to be immediately fed out so as to run on the pawls and the body advances while the front end thereof is supported by the pawls 12 gradually increasing in inclination. By this method, the timing of the opening start of the gate 1 and the feed-out of the body W becomes accurate still more.

Title: Disk stacker with positioning-aiding device
Inventor: DONAATO DOMINIKU EBUANGERISUTA
IPC: B65H15/00
Filed: 1991-08-08
Abstract: PURPOSE: To register the leading edge of a stacked sheet without damaging the sheet regardless of the weight thereof by constituting a rotary disc of a sheet supply means and a registration assisting means for releasing the sheet immediately after the leading edge of the sheet contacts a registration means. CONSTITUTION: A registration assist device presses a sheet located in the slot of a disc 30 against a surface of the disc 30 for a time which begins prior to and extends until just after the time when a leading edge of the sheet contacts a registration wall which strips the sheet from the disc slot. This pressing of the sheet causes a drag force to be applied to the sheet so that the leading edge of the sheet is re-registered with the registration wall to compensate for any bouncing of the sheet away from the registration wall after initial contact therewith. Preferably a foam roller 116 neighboring the disc 30 is moved into and out of a curved plane defined by the disc slot in timed relation to the rotation of the disc 30 to press the sheet against the slot surface.

Abstract: PURPOSE:To permit the perfect removal of fish-eye spitting as well as a long time operation without any breakage of a filter, by a method where a filter, having a filtrating capacity higher than the filter for a core layer, is used for a skin layer. CONSTITUTION:Aromatic polyester sulfon PES films, forming a skin layer and a core layer, are made by combining extruders, equipped with filters, through co-extrusion method. The filter, having smaller diameter of a media and higher filtrating accuracy than the filter for the core layer, is used for the skin layer while one to two sets of extruders are used for the skin layer and one set of extruder is used for the core layer. The filters, to be employed, are provided with a deep layer filtrating structure having the porosity of 5wt% of more while the average diameter of the media for the filter for the extruder for the skin layer is 20mum or less and the same for the extruder for the core layer is 10mum or more. The thickness of the skin layer is within the range of 3-20mum while the thickness of the core layer is within the range of 40-200mum. This PES film has no fish-eye spitting at all and is prominent in the appearance as well as the transparency thereof whereby the deterioration of long-run property due to the increase of a filtrating capacity may be resolved.
