Title: Fuel assembly for pressurized water nuclear reactor
Inventor: YOKOYAMA TAKASHI
IPC: G21C3/328
Filed: 1990-02-23
Abstract: PURPOSE:To extend fuel life and to reduce fuel cost by making a con-centration of fissile materials at an upper region above a certain position of a fuel assembly, to be lower than at a lower region in fuel assemblies under a loaded condition of a reactor core. CONSTITUTION:A concentration of fissile materials which are loaded to at least a part of positions of a fuel assembly higher than a position of around a half to a third length of a fuel rod from an upper region (down stream side of coolant flow) of the fuel rod, is made to reduce stepwisely, or gradually to an upper part from a lower part. In this way, since the concentration of fissile materials of the fuel assembly at an upper part of a reactor core is reduced, an output of fissile energy at the upper part of the reactor core can be reduced to reduce a surface heat flux. a boundary temperature of a metal and an oxidized film is lowered and an oxidizing speed can be also reduced.

Title: Servo track writer and magnetic disk device
Inventor: UNO MINORU
IPC: G11B21/10
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To enhance positioning accuracy by providing a means for scanning plural cylinders of a magnetic recording medium with a head in position, a means for recording discriminating information for showing a just adjacent cylinder and a means for recording servo mark to be a reference of word synchronization of this discriminating information. SOLUTION: Spaces of the plural cylinders to be formed on the magnetic recording medium are scanned at a pitch of a fraction of an interger of each space by the scanning means 11 with the head in position to these cylinders. The discriminating information showing the just adjacent cylinder to each scanning position is recorded by the position information recording means 12 with a phase given by a monotonous function for a physical offset to this just adjacent cylinder. The servo mark as the reference of the word synchronization of the discriminating information is recorded in a predetermined position of ratio of <=1 in a scanning position by the servo mark recording means 13. By this method, degradation of the sense level of the servo mark is mitigated, and the scanning can be performed without any jump of the scanning means 11.

Title: Method and device for determining quantity of cyan glycoside
Inventor: TATSUMA TORU
IPC: G01N27/416
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To detect only a cyan glycoside and determine its quantity accurately by applying a specific potential to an operation electrode, applying a potential at a positive electrode side after a while, and detecting the value of a current that flows in an electrode system. SOLUTION: When a potential of E1 =-300mVvs and Ag/AgCl are applied to the graphite electrode of an operation electrode for a specific amount of time, the reduction reaction of a dissolved oxygen in an electrolyte occurs and generated hydrogen peroxide is accumulated near the operation electrode (1). Then, when a potential of E2 =-0mVvs and Ag/AgCl are applied to the operation electrode, no reduction reaction of oxygen occurs and only a catalyst reduction reaction due to peroxidase of the accumulated hydrogen peroxide advances (2-4). On the other hand, cyan being generated by a linamarin hydrolysis reaction due to linamaraze (5) blocks a peroxidase activation (6), thus reducing the catalyst reduction current of the hydrogen peroxide under the coexistence of linamaze and linamarin.  Therefore, the quantity of linamarin in a cyan graphite can be determined by measuring the amount of reduced catalyst reduction current of the hydrogen peroxide.

Title: Method of confirming mixing state of binder and heat-insulation particle when heat insulation material is stirred
Inventor: TAKAHASHI YUKIO
IPC: G01D21/00
Filed: 1980-03-31
Abstract: PURPOSE: To simply confirm the mixing state of a binder and heat insulation particles when being mixed by adding a distinct colorant with a color tone different from that of the heat insulation particles to the binder in advance.  
     CONSTITUTION: When a heat insulation work is conducted by mixing heat insulation particles with a binder, a distinct colorant of red, blue, etc., having a color tone different from that of the heat insulation particles, is added in advance to the binder. Thus, the mixing state of the heat insulation particles and the binder can be best confirmed even when a smaller amount of the binder is used than the heat insulation particles. Accordingly, settling phenomenon of the heat insulation particles and the lowering of strength of the mixture due to the uneven dispersion of the heat insulation particles in the binder can be prevented, and heat insulation material can therefore be efficiently filled.

Title: Heat accumulator and heat-accumulator type air conditioner equipped therewith
Inventor: YOSHIDA NOBUHIDE
IPC: F25B1/00
Filed: 1989-02-22
Abstract: PURPOSE:To equalize the melting of ice by forming a cooling passage in which refrigerant passes through a heat exchanger and laying out this cooling passage so that it may run vertically and zigzag inside an accumulator. CONSTITUTION:A cooling pipe 10a of a heat exchanger 10 for heat storage service is laid out vertically in a zigzag manner inside an accumulator 9. More specifically, the cooling pipe is submerged in water W inside the accumulator 9, and its straight sections 10e at the both upper and lower ends located near its U-shaped section 10d is supported with a support base 9a vertically installed inside the accumulator 9 and laid out vertically. Since the cooling pipe 10a is laid out vertically during heat stored recovery cooling operation, the ice I adhered on the cooling pipe 10a is melted equally in a concentric circle with the cooling pipe 10a. As a result, the ice I which has melted by a specified amount, floats upward in the accumulator 9 along the cooling pipe 10a, which prevents the action of buoyancy over to the cooling pipe 10a and the deformation of the cooling pipe 10a as well. The ice which as floated, is exposed to the water W at a relatively high temperature, which prompts the melting of the ice and prevents old water W from remaining in one place.

Title: Refining method for stainless steel
Inventor: HOSHI NORIO
IPC: C21C7/076
Filed: 1980-04-03
Abstract: PURPOSE:To produce a high-quality stainless steel without using any special equipment and costly slag making agent by transferring the slag produced in a converter process together with molten steel into a degassing refining process for molten steel and subjecting the molten steel to deoxidation treatment by the diffusion deoxidation of this slag. CONSTITUTION:The slag which is produced in a refining process under atmospheric pressure in a converter and has been so controlled of its basicity (CaO/SiO2) as to assume >=1.0 is transferred together with molten steel into a degassing refining process under decreased pressure in a vacuum ladle degassing device. The deoxidation of the molten steel in this degassing process is accomplished by the slag diffusion of the above-described slag. It is preferable to control the slag basicity after the degassing as to assume 0.8-1.5 in this degassing process. To effectively execute the treatment of the slag diffusion and deoxidation in the degassing process, it is desirable to use a ladle provided with a porous plug in the bottom and stir the molten steel by blowing an inert gas through this plug.
