Title: Fuel assembly for light water reactor, part and alloy used for the fuel assembly, and its manufacture
Inventor: NAKAMURA KIYOMI
IPC: C22C16/00
Filed: 1994-03-18
Abstract: PURPOSE:To increase the corrosion resistance and to prevent a radiating damage, by composing the component member of a fuel assembly with a Zr radical alloy, and making the Zr radical alloy in an ultra-minute crystal grain size including Fe. CONSTITUTION:A fuel cladding pipe to cover a uranium pellet for fuel of a fuel is held by a spacer, and plural cladding pipes are housed in a channel box. At least one of these component members is composed of a Zr radical alloy, and its mean crystal grain size is made less than 1000nm, favorably making into an ultra-minute crystal with 10 to 100nm. As a result, a radiation defect by a neutron radiation is not generated in the crystal grains, so as to improve the neutron damage resisting property. And by fixing and solving a corrosion resistance improving element such as Fe in a Zr matrix, the corrosion resistance is improved. In this case, a high effect can be obtained by making the including ratio 0.5 to 30wt.%, being more favorable to be 1 to 5wt.%. By using a material in the ultra-minute crystal condition in which an alloy additive element is fixed and solved in the Zr in such a way, the component member of the fuel assembly can be obtained by applying a process and a heat treatment.

Title: Semiconductor substrate, and thermal ink-jet head using semiconductor substrate
Inventor: UENISHI KATSUZO
IPC: B41J2/16
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To simplify a constitution of a head frame in relation to a semiconductor substrate and a thermal ink-jet head and facilitate processing to the head frame. SOLUTION: Connection grooves 27a-27d for guiding a yellow(Y) ink, a magenta(M) ink, a cyan(C) ink and a black(Bk) ink to ink feed holes 26a-26d are formed at a rear face of silicon wafer 23. The ink of each color supplied from an ink container connection part of a head frame through the connection grooves 27a-27d is sent to the corresponding connection grooves 27a-27d to the ink feed holes 26a-26d. Since the connection grooves 27a-27d are formed sat the side of a semiconductor substrate, the head frame where the connection grooves are formed conventionally is simplified in structure. The formation of the connection grooves 27a-27d a the side of the semiconductor substrate 22 is considerably simply realized, e.g. by changing a mask pattern at a conventional work.

Title: Magnetizing yoke
Inventor: SATO NAOJI
IPC: H01F13/00
Filed: 1991-02-22
Abstract: PURPOSE:To enable a permanent magnet to be sufficiently magnetized by a method wherein a circular ring type magnetizing yoke is formed of a permanent magnet material while windings are made in a multitude of trenches formed inside the circular ring so as to concentrate the magnetic flux of the magnetizing yoke in the easily magnetizing direction of the permanent magnet material. CONSTITUTION:A permanent magnet 24 to be magnetized is inserted into the inner diametral part of a magnetizing yoke as shown in Fig.1 so as to magnetize the permanent magnet 21 of the magnetizing yoke while windings 23 are fed with specific current to generate magnetic flux around the windings 23 as shown in Fig.2. At this time, the magnetizing yoke 21 comprising a permanent magnetic material is also magnetized together with the permanent magnet 24. Next, when the current is shut off to remove the permanent magnet 24, N, S magnetic poles are alternately made on the surface of the part not forming the trenches due to the residual magnetism on the magnetizing yoke 21 as shown in Fig.3. Through these procedures, the permanent magnet 24 can be inserted while turning into the magnetizing yoke 21 so as to automatically align the easily magnetizing direction of the permanent magnet 24 with the part not forming the trenches due to the function of the magnetic poles made on the ends of the part not forming the trenches so that the permanent magnet 24 may be sufficiently magnetized by feeding the windings 23 with specific current.

Title: Desulfurizing and denitrating method for combustion exhaust gas
Inventor: SHIMAZAKI KOICHI
IPC: B01D53/60
Filed: 1987-03-02
Abstract: PURPOSE:To increase desulfurizing and denitrating efficiency of exhaust gas containing a small volume of sulfur oxide by allowing additionally sulfur oxide be adsorbed into active carbon prior to regenerating activated carbon exhausted by being contacted with combustion exhaust gas. CONSTITUTION:Exhausted activated carbon discharged from the bottom of a desulfurizing and denitrating column 5 is fed to the top of an activation column 7 and flowed down inside the column by means of gravity, and sulfur oxide is adsorbed additionally to the activated carbon by contacting gas composed of gas containing sulfur oxide from a regenerating column 8 and a proper volume of air with activated carbon moving bed in the activation column 7. Then, said activated carbon is drawn out of the bed of the activation column 7, and fed to the top of the regenerating column 8, and the activated carbon is regenerated by heating up the moving bed for the exhausted activated carbon flowing down inside the column by means of gravity in the inactive gas atmosphere. After regeneration, the activated carbon is fed to the top of desulfurizing and denitrating column 5 to be used for the treatment of exhaust gas again.

Title: Morpheme alanysis, syntax analysis and morpheme forming system
Inventor: ITO NORIKAZU
IPC: G06F17/27
Filed: 1990-02-28
Abstract: PURPOSE:To flexibly execute composite word processing by registering the whole composite word formed through a specific character in a translating temporary dictionary to be used for translation processing such as syntax analysis as an unknown word when the composite word is not included in a dictionary. CONSTITUTION:When a composite word formed by a specific character such as a hyphen (-) forming one composite word by mutually connecting plural words is included in a test to be analyzed in a morpheme analyzing part in a translation body part (translation part) 7, the composite word is retrieved by a dictionary 8 included in the system. When the composite word is not included in the dictionary, the whole composite word is registered in the translating temporary dictionary to be used for the translation processing such as syntax analysis as an unknown word. Since the retrieval of a composite word formed by connecting plural word through a specific character such as a hyphene in the dictionary by the morpheme analyzing part is improved, proper processing interlocking with the succeeding processing of the syntax analyzing part is executed even when the syntax analysis result of the composite word succeeds or fails. Consequently, the processing of the composite word based upon the specific character such as a hyphene can be flexibly executed.

Abstract: PURPOSE: To make the ion irradiation quantity to a wafer uniform by measuring the irradiation quantity of an ion beam to the wafer and successively changing the irradiation position of the wafer with respect the ion beam.  
     CONSTITUTION: The wafer 29 is fixed to a platen 108 by a clamp assembly 110 in a vacuum chamber 32 and a tilting motor 73 is excited to rotate a wafer supporting part 38 around an axial line 80, by which this supporting part is arranged to the desired implantation position.

Title: Method and apparatus for induction heating of gear tooth
Inventor: JIYOOJI DEI PUFUAMAN
IPC: C21D9/32
Filed: 1990-03-02
Abstract: In a process and apparatus for inductive hardening of the corrugated surface of a workpiece, in particular the toothing of a gearwheel or sprocket, a uniformly distributed hardness pattern reaching down to a controlled depth is achieved on the teeth by scanning the workpiece surface to be hardened with a single inductive heating coil (12), while the workpiece is taken past the inductive heating coil. A special final heating scanning the workpiece follows a preheating scanning the workpiece, it being possible for the preheating and final heating to be carried out at different controlled speeds. The repeated scanning of the workpiece (W) past a single inductor coil (12) permits the preheating and final heating of workpieces which cannot be taken directly past separate inductor coils in the axial direction, as is the case, for example, with planetary gearwheels having inner ring toothing and a closed end (12), or as is the case with spurgear wheels which have a flange projecting beyond the cylindrical tooth face or a radially projecting shoulder. <IMAGE>
