Title: Method and device for control of water quality for boiling water reactor primary cooling system
Inventor: NAGASE MAKOTO
IPC: G21D3/08
Filed: 1991-01-18
Abstract: PURPOSE:To contrive the control of zirconium corrosion acceleration caused by copper ion existing in cooling water by calculating the lack of iron concentration from the measured data of iron and copper concentration in the cooling water to control an iron content to an optimum quantity in the cooling water. CONSTITUTION:A sample gathered through a sampling line 13 set in the upstream side of a reactor purifying facility 12 in regard to copper concentration in reactor water is measured by the use of a concentration measurement device 14. The concentration ratio of Fe/Cu is calculated from the measurement, when the ratio is 2 or less, a quantity of iron injected into supply water from an iron production device 15 in the outlet side of a condensate demineralizer is increased by enlargening the opening of an infection control valve 16 to increase a quantity of injection iron until the ratio of Fe/Cu in the reactor water becomes 2 or more. Thereby copper adhered to the surface of a fuel rod can be settled into the chemical state of a stable ferrite oxide and the acceleration of zirconium corrosion can be prevented.

Title: Manufacture of vacuum envelope and manufacturing device thereof
Inventor: SATO SHOZO
IPC: H01J9/28
Filed: 1993-01-14
Abstract: PURPOSE:To form an electric terminal to pass penetratingly through a vacuum envelope without requiring skilled technique by softening a glass part by heat of heat conduction from a mainly heated jig, and welding the electric terminal to the part. CONSTITUTION:An electric current is flowed to a high frequency coil 5, and a jig 4 is heated to about 1000 deg.C. Heat of the jig 4 is conducted to an electric terminal 2 or a glass part 1, and the part 1 is softened. The terminal 2 is welded to the part 1. Since the terminal welded part 1 is softened by heat from the jig 4 when the terminal 2 is welded, it is molded in a shape running along an inside surface of semi-spherical space 4b on the lower end of the jig 4. In this case, when a glass bead 3 is stuck on the terminal 2, a bead 3 part is brought into contact with a recessed part 1a in the center of the part 1, and the terminal 2 is inserted in a through-hole 1b, and the tip of the terminal 2 is projected slightly downward from the part 1. Thereby, skilled technique is not necessary, and even if a glass quantity is plenty, the terminal 2 can be welded excellently, so that quality can be improved.

Title: Substrate for optical disk and its production
Inventor: SAITO MIKIKO
IPC: G11B7/2405
Filed: 1993-01-14
Abstract: PURPOSE:To lower noise and C1 error rate by setting the shrinkage rate and surface roughness of a substrate within a prescribed range. CONSTITUTION:The front surface of the transparent substrate 1 consisting of a polycarbonate, etc., is provided with a sol-gel layer 3. Guide grooves 1 for tracking are formed atop this gel-sol layer 3 by using a glass master or the stamper for reproducing the substrate produced by subjecting this master to nickel electroforming. A magneto-optical recording film 4 is deposited on the surface formed with the guide grooves 1. The surface roughness is lowered to <=15nm by selecting the shrinkage rate x of the sol-gel layer 3 at a relation [surface roughness rmax]X[shrinkage rate x]<15nm. The noise and C1 error rate are improved by lowering the surface roughness. The C1 error refers to a ratio of the number of errors actually corrected with respect to a correctable error correction rate in the unit time in each unit block in the error correction system to be used for CDs.

Title: Data flow processor
Inventor: SAKAI HIROSHI
IPC: G06F15/82
Filed: 1984-01-13
Abstract: PURPOSE:To attain the parallel processing for transfer of data and to increase the processing speed of a data flow processor, by using a detecting function for data transfer to plural bus groups as well as a simultaneous access function for memory addresses of instructions. CONSTITUTION:The instructions stored in a memory part M are sent to the 1st bus groups Bus1-1-Bus3-1 via an interface part Di together with data and then undergo the airthmetic processing through corresponding arithmetic parts f1-f3 via an interface R. The results of the arithmetic processing are delivered after the idle state is decided at an arithmetic output interface part D for the 2nd bus groups Bus1-2-Bus3-2. Then an interface part A of the part M decodes the address information to which the next execution instruction is designated for the data on the 2nd bus groups when these groups are filled. Then an access is given to an instruction corresponding to the decoded information from the part M. This instruction is sent to the 1st bus together with the next arithmetic object data through the part Di. Then the transfer of data is processed in parallel. This can accelerate the processing speed of a data flow processor.

Title: Sintered and forged product
Inventor: TOMINAGA KOJI
IPC: C21D7/06
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce decarburizing layers in the surface part of a sintered and forged product without executing machining after forging by subjecting the surface part of a sintered body to cold mechanical sealing treatment and thereafter executing hot forging. SOLUTION: Decarburization is not generated by cold sealing treatment, but, by crushing pores in the surface part of the sintered body prior to forging, when the sintered body is heated by reheating in hot forging, decarburization in the surface part of the sintered body is made small. Namely, the depth of the decarburizing layers after the forging is made shallow of <=0.1mm. Furthermore, the strength of the surface part of the forged body sufficiently increases because pores therein are mechanically crushed by sealing treatment. Thus, there is no need of executing machining after the forging for removing decarburizing layers. As the sealing treatment, a shot peening treatment or a shot blasting method can be used. By the above, pores over the whole body of the surface can securely be crushed even in a sintered body having an exceedingly complicated surface shape.

At this time, after the conclusion of rolling, cooling is carried out down to 500 deg.C at <=0.1 deg.C/s cooling rate, by which ferrite fraction in the steel structure is remarkably increased and lamellar spacing in a pearlitic part is widened to carry out softening. By this method, the directly softened steel wire rod or steel rod capable of eliminating or simplifying heat treatment prior to secondary working can be obtained.

Title: Equipment and method for managing memory in copying machine
Inventor: TEIMU DEII HAMAA
IPC: B41J5/30
Filed: 1994-01-21
Abstract: PURPOSE: To reserve a memory in accordance with the actual requirements of an IOT by supplying a substrate to an image outputting terminal correspondingly to a prescribed amount of memory space in which a used memory can be used to the maximum amount and when an additional prescribed state is met. CONSTITUTION: A marker reserves 5 memory for the sheet corresponding to a received video hint. Then the marker decides whether or not the space of a buffer 162 can be reserved by referring to a resource manager 57. The marker decides the maximum memory amount to be used and sends the amount to the resource manager 57. The manager 57 discriminates whether or not the amount exceeds the usable memory amount assigned to an IOT. When a sufficient amount of memory is not usable, the processing enters a wait state until a sufficient amount of memory becomes usable. Therefore, memory reservation can be made in accordance with the actual requirements of the IOT.
