Title: Thermo-hydric grid and nuclear fuel assembly
Inventor: JIYANNNOERU KANATSUTO
IPC: G21C3/322
Filed: 1992-06-01
Abstract: PURPOSE: To ensure uniform mixing of steam by coupling the surround not directly with a strap but with several simple guides and providing a surround for resisting the impact. CONSTITUTION: An addition grid 36 having mixing blades 48 comprises two sets of intersection straps 42, 44 having a pad 46 separating two continuous supporting grids 20. The straps 42, 44 are secured, at the intersection thereof, to a simple guide 16a by means of the pad 46 while providing a space where a fuel rod supporting grid 18 can slide. A surround 52 around the intersection is fixed, at the upstream and downstream end parts thereof, with guide vanes 54 in order to prevent the grids 20 from hooking each other when a fuel assembly 10 is inserted or removed. The surround 52 is secured through two pairs of extensions 56 to a guide 16b not coupled with the intersection. Since a gap is formed between the straps 42, 44 secured to a guide 16a, impact of the surround 52 causes no damage on the straps 42, 44 and has no effect on the coupling structure of rod grid arrangement.

Filed: 1979-10-31
Abstract: PURPOSE: To prevent the overcurrent from being flowed to the load at a normalcy time, by providing an overcurrent detection point in the normal output voltage besides the overcurrent detection point in the output voltage for test.  
     CONSTITUTION: Switch SW is provided where voltage change-over switch SW(I) and overcurrent protection detection point change-over switch SW(II) are operated while interlocked with each other. Split resistances R 5  and R 6  are so determined that the overcurrent protection detection point for normalcy may be current I 1  for output voltage V 1  for normalcy. Consequently, when switch SW is turned off, the output voltage and the output current are controlled to V 1  and I 1  at a normalcy time. Meanwhile, when switch SW is turned on for test, resistances connected to switch SW are connected in parallel, and the overcurrent protection detection point is switched from I 1  to I 2 , and the output voltage and the output current are V 2  and I 2  at a test time. Thus, the overcurrent can be prevented from being flowed to the load for normalcy.

IPC: B24B9/00
Filed: 1989-06-02
Abstract: PURPOSE:To automate a work to remove burrs by a method wherein a disc sander having a balance weight and rockably supported to the chamfering part of a steel plate in a manner to make profile contact with the chamfering part are arranged in a longitudinal direction. CONSTITUTION:A disc sander to be chamfered is brought into pressure contact with the cut end surface of a steel plate by a profile contact system and is caused to follow waviness and the uneven surface of the cut end surface of the steel plate. Besides, a pressure contact force is regulated by means of a balance weight, and rough chamfering is automatically effected with high efficiency by profile grinding by means of a rigid grinding stone. A belt sander 59 by which finish chamfering is effected softly and resiliently grinds the cut end surface of the steel plate after chamfering. In this case, since a polishing position is set to a free running part 84 between guide pulleys 77 and 78, secondary production of burrs is prevented.

Filed: 1995-06-08
Abstract: PURPOSE: To reduce any noises out of low and high frequencies upon pressing the outer boundary central part and both the ends of a disk pad by forming a pressing surface to press this disk pad by means of a conical surface made up with the turning shaft of a disk rotor as the center. CONSTITUTION: When a brake operating member of a vehicle is operated, brake hydraulic pressure is induced into a pressure chamber 3c from a master cylinder, and a piston 4 is shifted to the left, whereby an inner disk pad 5 is pressed toward a disk rotor via a shim plate 9. On the other hand, a cylinder body 3 is shifted to the right by dint of the hydraulic pressure taken into the pressure car 3c, while an outer disk pad 6 is pressed toward the disk rotor via a shim plate 8 by means of a rear cushion part 3d of the cylinder body 3. At that time, since a pressing surface to press the outer disk pad 6 is formed by a conical surface made up with the turning shaft of the disk rotor as the center, any brake noises are thus reducible.

Abstract: PROBLEM TO BE SOLVED: To improve reliability by coupling a tower through which exhaust gas flows vertically downwardly with another tower located on a forward stream side through which exhaust gas flows vertically upwardly, and blowing powder into the upstream side tower and holding it at a floating state. SOLUTION: Exhaust gas produced in an electric furnace 1 enters an inlet side duct box 6 from a water cooling flue 2, a combustion tower 3, a water cooling flue 4, and a header pipe 5. Further, it flows through a tower A 7 vertically upwardly, and enters a tower B 9 after passage through a 180 degree bent pipe 8 where it flows vertically dwonwardly. During this the exhaust gas is made harmless and flows into a dust box 10. Powder such as slaked lime is supplied from a powder supply apparatus 14 through a piping 15 to a powder supply hole 13 disposed below the tower A 7, and is held at a floating state at all times. As the powder there may be used dust and activated charcoal, etc., from the electric furnace collected by a dust collector.

Title: Image file management device, its method and computer- readable storage medium
Inventor: FUKUZAWA KEIICHI
IPC: H04N5/76
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To allow the title management device to manage contents of many image files from a DIF file reproduced by a VTR and captured by a personal computer in an easy understandable way. SOLUTION: Compressed image data received from an input section 10 and extracted from a DIF file are subjected to decoding, 1-frame storage and JPEG compression, and a JPEG file generating section 24 receiving the processed image data generates an image file. Furthermore, extracted audio data are decoded in time series and stored for a prescribed time, read synchronously with the frame unit processing of the image data and converted into data of a WAV form. Furthermore, a name of the image file is generated on the basis of system data. Contents of the image file can easily be recognized by reproducing a voice recognition file that is generated through the synthesis of the generated file name and the audio data of the WAV form.  Moreover, since the two file names are the same except for their identifiers, the voice recognition file corresponding to image data can easily be found out even in the case of file management by means of a personal computer.
