Title: Manufacture of laminated core
Inventor: MASUDA KOICHIRO
IPC: H02K15/02
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To manufacture products different in number of laminated layers without shutting down presses, by entering and storing a plurality of pieces of data of products different in shape in a preparative data setting phase prior to manufacture, and automatically varying the shapes of the products according to the set numbers of units during a core piece stamping phase. SOLUTION: When a controller is fed with the dimensions and shapes of CB's (counter bores) and the thickness of stamping material through a touch panel 4 for data setting, the controller automatically converts the data through PLC 2 and sets the number of laminated layers and shape for each CB. Further, the controller calculates numbers of layers laminated during a period from start of laminating to issuance of a command to vary the shape to a solenoid, according to the number of laminated layers for each CB. In addition, the controller specifies a panel 4 for data setting for CB for which a number of laminated layers has been specified.  Usually, the number of laminated layers is counted according to signals from a press, and when the counted number of laminated layers reaches the set number of laminated layers for a CB, a signal is sent to the solenoid 3 to change the punching shape to that of another CB.

Title: Fuel assembly
Inventor: NOMOTO SHOJI
IPC: G21C3/30
Filed: 1993-03-09
Abstract: PURPOSE:To obtain a fuel assembly enabling positive and sure attainment of negative core reaction insertion on the occasion when the temperature of a coolant rises abnormally at the time of ATWS (transient fluctuation). CONSTITUTION:In a fuel assembly 10 constituting the core of a reactor, a fuel inovable part whereby a part or the whole of a group of fuel pins 11 disposed in this assembly 10 is made movable upward or downward inside the assembly 10 under the gravity or a fluid pressure from a coolant, a release mechanism 20 which locks the axial movement and rotation of the fuel movable part at the time of an ordinary operation and releases this part from the locked state when the temperature of the locked part exceeds a prescribed limit value at the time of an abnormal rise of the temperature of the coolant, and a relocking mechanism 25 which locks the fuel movable part after it moves, are provided. Setting is so made as to lead the reactor to shutdown by utilizing the negative reactivity which is produced by changing the relative positions of the fuel movable part and the core by giving rise to the axial movement of the fuel movable part when the temperature of the coolant rises abnormally.

Title: Manufacture of electrical contact material
Inventor: YAMADA SHIYUUJI
IPC: H01B1/02
Filed: 1980-04-12
Abstract: PURPOSE: To obtain an electrical contact material contg. uniformly dispersed metallic oxide and having no layer lacking in the oxide by impregnating a silver alloy into a network skeleton made of material hardly soluble in silver and carrying out internal oxidiation to reduce the oxidiation time.  
     CONSTITUTION: A silver alloy is impregnated into a skeleton made of material such as nickel hardly soluble in silver and having three-dimensional irregular network structure. Internal oxidiation is then carried out to oxidize the solute metal of the silver alloy. At this time, oxygen reaches the interior uniformly and deeply through the interface between the skeleton and the impregnated alloy, so the oxidiation is carried out uniformly in a short time without forming a layer lacking in oxide. The resulting electrical contact material has high endurance since the impregnated silver-metallic oxide is being protected by the skeleton.

Title: Light beam soldering device
Inventor: TSUCHIYA HITOSHI
IPC: B23K1/005
Filed: 1989-03-02
Abstract: PURPOSE:To shorten the irradiation time of a light beam and to obviate the generation of a printed circuit board burn by heating liquid to a prescribed temp., discharging the liquid to the prescribed position on the rear of the printed circuit board and thereby preheating the circuit board. CONSTITUTION:A flat package IC 7 is mounted on the solder applied on the wiring patterns of the circuit board 2 and is stopped at a prescribed position. A water tank 33 rises and the circuit board 2 is supported by a circuit board supporting rod 36. The preheated hot water is discharged from a hot water discharge pipe 35 to the corresponding position on the rear of the flat package IC 7 from the rear side of the circuit board 2 to preheat circuit board 2. A laser beam L successively scans leads 7a to solder the lead. The water tank 33 is lowered and the discharge of the hot water is stopped. The circuit board 2 is delivered to complete the soldering. Since the circuit board is preheated, the time for irradiation with the light beam is shortened and since the liquid evaporates in the heating part where the temp. rises extremely, the generation of the circuit board burn is obviated.

IPC: H01G9/035
Filed: 1990-02-27
Abstract: PURPOSE:To improve the affinity of an electrolyte for an aluminum electrode and for an electrolytic paper and also to improve the impregnating ability of the electrolyte for an element remarkably by dissolving boric acid or its salt in a solution mainly composed of ethylene glycol and further by adding a specific wt.% of polyoxyethylene nonylphenyl ether or polyoxyethylene dinonylphenyl ether.

The bias of the concentration of hydrogenphosphate-ammonium to be mixed normally for forming properties of the electrolyte and for suppression of the reaction of the electrolyte and electrode has an adverse effect on the initial characteristics and reliability of an electrolytic capacitor. However, said electrolyte remarkably suppresses the bias of the distribution of concentration of hydrogenphosphate-ammonium so that an impregnating ability is improved irrespective of the composition of the electrolyte.
