Title: Nuclear reactor control rod driver
Inventor: IZUMITANI MASAKIYO
IPC: G21C7/12
Filed: 1978-02-10
Abstract: PURPOSE: To raise the resistance of a sliding connector to wear and corrosion and eliminate the emission of strong radioactivity such as from radioactive cobalt, by making the sliding connector from a material produced by coating a metal with a hafnium carbide.  
     CONSTITUTION: For example, soft steel SS41, stainless steel 304 or nickel alloy consisting of 15.5% of Cr, 8% of Fe, 0.08% of C and the rest of nickel is used as the coated metal. The hafnium carbide is coated at a thickness of 3 μm or more on the surface of the metal. The main radioactive nuclides, which are produced when neutrons are irradiated to the hafnium carbide in a nuclear reactor, are  175 Hf and  181 Hf. The half-life period of each nuclide is as short as 100 days or less. The gamma-ray energy, which is emitted from each nuclide, is not higher than 0.4 MeV and therefore does not matter to handling. To coat the hafnium carbide on the metal 1, metal hafnium 4 is set in an electric furnace 3 and the furnace is energized.

Title: Filter medium
Inventor: KAWAMURA TSUTOMU
IPC: B01D39/04
Filed: 1980-02-06
Abstract: PURPOSE: A filter medium which consists of small pieces of materials having rubber elasticity and by which extremely high filter and regeneration efficiency is obtained.  
     CONSTITUTION: Materials having rubber elasticity consisting of natural rubber, synthetic rubber and the like such as natural rubber, styrene-butadiene rubber and the like are ground to small pieces of roughly 1W10mm diameters. Next, a packing layer is formed of these small pieces alone or together with other filter materials, and the thus formed layer is used as a filter medium. When exerted with filter pressure, this filter medium compresses to have smaller voids, thereby filtering out down to the small-sized solids in the liquid to be treated with good efficiency. On the other hand, if no filter pressure is exterted thereon, the filter medium restores the original shape owing to rubber elasticity, and at this same instant, it releases the cake having deposited in the spaces among the small pieces to the outside through these spaces, thereby making the occurrence of clogging difficult. Hence, it assures the filtration process which does not cause clogging for a long period of time and offers high filtration efficiency.

Title: Image-forming element and image reader
Inventor: FUJITA KAZUHIRO
IPC: G02B27/18
Filed: 1989-01-24
Abstract: PURPOSE:To prevent image points from being separated from conjugate points in response to eccentric quantity and to prevent resolution from being deteriorated by symmetrically arranging a pair of lenses formed under an identical condition between an optical path separating mirror and a roof mirror. CONSTITUTION:The pair of lenses 12 and 13 are arranged between the optical path separating mirror 10 and the roof mirror 11 and are formed under an identical condition. Besides, the lenses 12 and 13 are symmetrically arranged in close contact with each other so that an axis in a direction (Y direction) orthogonal to both the ridgeline direction (Z direction) and the optical axis direction (X direction) of the roof mirror 11 is a rotating symmetrical axis. Then, even if the curved surfaces of the lenses 12 and 13 are eccentric, each eccentric quantity is identical. Besides, since the lenses are symmetrically arranged, eccentricity is canceled when light fluxes pass the lenses 12 and 13. Therefore, the image points and the conjugate points constantly correspond to each other and the dislocation of image-forming positions is prevented. Then resolving power is heightened.

Title: Preventing method for production of precipitate on bottom of excavated hole
Inventor: YAMAMOTO KIMIO
IPC: E02D5/36
Filed: 1979-02-14
Abstract: PURPOSE: To enable casting of concrete at once while the production of precipitate is prevented, by a method wherein muddy water treated to prevent the precipitation of solid particles of the hole is thrown into the bottom of a hole immediately after the excavation for the replacement thereof with that in the vicinity of the bottom portion of the hole.  
     CONSTITUTION: The treated muddy water 7 is prepared in which individual solid particles are prevented from precipitating since such a material as cement which gives cohesive power to the particles is thrown into the muddy water to generate mutually-tractive force to the particles. After the completion of excavation, in the meanwhile, a pit 2 is lifted slightly up from hole bottom 6 and rotated to circulate only the muddy water in opposite direction so that the muddy water which has a large specific gravity because excavation chips are contained and readily produces precipitate is discharged through pipe 3. Next, the treated muddy water 7 is thrown onto the hole bottom 6 through the head portion of a drill pipe 3 for replacing the muddy water in the vicinity of the hole bottom therewith. Next, the pipe 3 and pit 2 are drawn up, a reinforcing bar basket 8 and a tremie pipe 9 are inserted into an excavated hole 1, and concrete 10 is cast onto the hole bottom 6 so that a pile is completed.
