Title: Data storage system for disk device
Inventor: NAKAZAWA HARUMI
IPC: G06F3/06
Filed: 1989-11-02
Abstract: PURPOSE:To easily execute the release of storage data, when a fault occurs in a disk device by executing double storage of a Millard system to two sets of corresponding disk devices. CONSTITUTION:When an error is generated in read-out data, a main control part 1 reads out and uses the same data through a disk control part 22 from the corresponding position of a disk device 32-i. Subsequently, at the time of restoration, the main control part 1 stores the same data read out through the disk control part 22 from the corresponding position of the disk device 32-i in the original position of the disk device 31-i in which an error occurs through a disk control part 21 and confirms it. In such a manner, when the fault is generated in the disk device, the restoration of the storage data can be easily executed.

Inventor: FURUSE TAKASHI
IPC: C09D11/30
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To lessen defective products resulting from the defect of electron emitting portions by using an organic metal compound expressed by a specified formula in a member for forming electron emission portion by which the electron emission portion is formed via a heating and burning process of the organic metal compound. SOLUTION: In the formula 1, R<1> , R<2> , R<3> = alkali group of carbon count 1 to 4, 1 = integer of 2 to 4, m = integer of 1 to 4, k = integer of 1 to 2, n = ingteger of 0 to 1, M = metal. Single or plural organic metal media are contained, and the aqueous solution thereof is used. The metal concentration range of the aqueous solution of 0.01% to 10% is generally proper. In the case of the low metal concentration range, an unnecessarily large puddle is produced on a board, and a purpose to impart metal to only a required position is not attainable. Reversely, when the metal concentration of the solution is too high, the puddle imparted to the board becomes significantly non-uniform in the case of drying or burning, and as the result the conductive film of an electron emission portion becomes non-uniform so that the characteristics of an electron emission element are deteriorated.

Title: Production of wire rod excellent in wire drawability
Inventor: NISHIDA TSUGUNORI
IPC: C21D9/52
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To improve the wire drawability of a wire rod by subjecting a wire rod contg. a specified amt. of C, in which wire diameter is regulated to specified value or above and half or above of cementite present in the cross section of the wire rod is composed of upper bainite to heating at a temp. and time in specified ranges. SOLUTION: The content of C in the wire rod is regulated to >=0.6%. But, the upper limit is regulated to 1.2% in consideration of deterioration in the ductility. The workability of the steel depends on the shape of cementite, but, the form of cementite is parted, and the upper bainite structure wide in the interval is excellent in wire drawability. However, since it is the structure produced at a low temp., the thicker the wire diameter is made, the more difficult the simplification of the bainitic structure is made. Therefore, regulation is executed in such a manner that >=50% of the cross section of the wire rod is composed of the bainitic structure, after that, tempering is executed in the range of 400 to 650 deg.C, and the holding time is regulated to 300 to 900 sec.

Inventor: KOBOSHI SHIGEHARU
IPC: G03D15/00
Filed: 1986-12-03
Abstract: PURPOSE:To decrease generation of harmful and malodorous components by heating the upper part of a waste photographic processing liquid and evaporating and concentrating the liquid in such a manner that the temp. difference between the waste liquid near the heated part and the bottom of the waste liquid is increased to a specific temp. or above by convection, thereby settling the eluted material in the waste liquid.

Title: Hydraulic device for control rod drive
Inventor: SHIRAISHI HIROYUKI
IPC: G21C7/16
Filed: 1990-10-29
Abstract: PURPOSE:To prevent an excessive pressure rise and prevent the occurrence of damage to each part by providing a bypass flow passage and a pressure release means in the valve box of a gate valve at a connection line between the upper cylinder chamber of a control rod drive mechanism and a scram discharge facility. CONSTITUTION:Normally, a ball 45 as a pressure release means is kept in contact with a seat section 51 under pressure by a spring 44, thereby interrupting a bypass flow passage 50. If a control rod drive hydraulic device 1 scrams with the main flow passage thereof closed due to the erroneous operation of gate valves 41 and 42, a section continuous to the upper cylinder chamber of a control rod drive mechanism, or the upstream port 48 of the valves 41 and 42 gives higher pressure. In addition, when the pressure becomes equal to or above the predetermined level, the ball 45 parts from the seat section 51 against the force of the spring 44, thereby enabling the pressure of the port 48 to be released to a downstream port 49 via the bypass flow passage 50. According to the aforesaid construction, an excessive pressure rise is prevented, even if the device 1 scrams with the gate valves 41 and 42 closed, and the damage of each section can be avoided. As a result, the safety and soundness of plant operation can be enhanced.

Title: Multilayer circuit board and manufacture thereof
Inventor: USHIFUSA NOBUYUKI
IPC: H05K3/46
Filed: 1989-11-08
Abstract: PURPOSE:To enable high-speed transmission by lessening the permittivity of insulating layers between X-direction and Y-direction line wiring layers and power source layers or ground layers, and enlarging that of the insulating layers between the X-direction and Y-direction line wiring layers and between the power source layers or ground layers. CONSTITUTION:The permittivity of the insulating layers 2 between X-direction and Y-direction line wiring layers 3 and power source layers 4 or ground layers 4 is made to be smaller than that of the insulating layers 1 between the X- direction and Y-direction line wiring layers 3 and between the power source layers 4 or ground layers 4. Namely, an insulating material 1 provided with an air and a line wiring layers 3 on both faces and an insulating material 1 provided with a power source layer 4 or a ground layer 4 on both faces are composed of ceramics, etc., whose main component is mullite. As this result, the magnetic fields between the line wiring layers 3 and power source layers 4 or ground layers 4 are hardly generated, and the transmission of electric signals is not interfered. In this way, it becomes possible to transmit electric signals quickly.
