Title: Manufacture of permanent magnet
Inventor: ARAI SEI
IPC: H01F1/053
Filed: 1990-05-11
Abstract: PURPOSE:To obtain a highly efficient R-TM-B permanent magnet at low cost by a method wherein the interior of a mold is depressed when casting the alloy fundamentally composed of rare-earth element (provided that Y is contained), transition metal and boron. CONSTITUTION:For example, an alloy is composed of Pr of 17 atomic %, Fe of 76.5 atomic %, B of 5 atomic % and Cu of 1.5 atomic %. First, a melting furnace is brought in an argon atmosphere, and the above-mentioned alloy is melted in a crucible 205 by induction heating. Then, a casting mold 201 is decompressed using a vacuum pump 207, melted alloy 204 is sucked up into the water-cooled mold 201 from the crucible, and the desired alloy ingot is cast. A hot working process and a heat treatment process are conducted on the cast ingot obtained as above. For example, after an annealing treatment has been conducted on the ingot at 1000 deg.C for 24 hours in an argon atmosphere, a heat treatment is conducted at 475 deg.C for two hours in an argon atmosphere.

Title: Method of controlling hot water filling amount in full-automatic bath boiler provided with hot water supplier
Inventor: FUKUYOSHI KENZO
IPC: F24H1/00
Filed: 1985-06-07
Abstract: PURPOSE:To provide a method of controlling the amount of hot water to be filled which is compact in the execution work, inexpensive in cost and convenient for use by burning a bath burner only for a certain specific time and computing the necessary amount of hot water to be filled based on a difference in temperature between residual water before and after the burning. CONSTITUTION:When a bath flowing water switch 7 is turned ON, the temperature t1 ( deg.C) of residual water is detected by a bath temperature detector 8 and this is stored in a bath computing circuit 18. Then, the bath computing circuit 18 outputs a signal to a timer circuit 21, and a relay K4 is actuated only during a specific time T(hr). A contact SW4 of a bath proportional valve 25 is closed by this period of time to burn a bath burner 10. Further, the bath computing circuit 18 judges that there is no residual water in the bathtub in a case where the bath flowing water switch 7 is not turned ON inspite of the operation of a pump 6, and computes the full hot water filling amount required for the bathtub. Thereafter, a water filling signal is input to a water electromagnetic valve driving circuit 23 and a water amount computing circuit 20.

Filed: 1990-05-11
Abstract: PURPOSE: To give a multicolor print for easily changing a color by a visual angle by conducting a repetitive change of optical characteristics in an area of a figured medium having a line pattern oriented in a plurality of different directions in a section form area, and changing the color synchronously with it. CONSTITUTION: A part 10 of a print having a changing color has a cloud 12 partly specified by sectional forms 14, 16, 18, 20, and the respective sectional form areas have lines oriented differently. These lines are established by grooves 22, 24, 26, and the grooves are formed by embossing a foil 29 on a base layer 27 by thermal transferring. Repetitive colors 28 are printed by aligning synchronously with the grooves on the foil 29, and include a yellow fringe 30, a magenta fringe 32 and a cyan fringe 32. The groove 24 reflects a magenta light emitted by a ray 46, sensed by a visual angle of an observer 40, and the cyan color emitted from the fringe 30 illuminated by the ray 46 is not sensed. However, when the observer 40 is moved to a position of an observer 42, the cyan color is sensed at the visual angle.  A different visual angle is performed by transferring a light source to a position of a light source 50.

Title: Method for automatically filling bath with hot water
Inventor: KATAOKA HISATO
IPC: F24H1/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent a large quantity of hot water from overflowing a bath when filling water automatically by obtaining the minimum quantity of water where reheating circulation is allowed from a state without any remaining water, by using the quantity as the minimum reference quantity of remaining water of the quantity of operation remaining water, and by calculating required quantity to be added when making the trial run of the bath. SOLUTION: When the automatic hot-water-filling operation of a bath is started, a controller 50 commands that each part of a device should supply, for example, 10 l, hot water from a bath hot-water-supply pipe 25 into the bath. After 10 l hot water is supplied, a circulation pump 43 is driven and a water current sensor 45 detects whether water in the bath is circulated to a reheating circulation path 40 or not. When the water is not circulated, it is commanded that quantity where 10 l hot water being supplied previously is subtracted from the preset quantity of water should be supplied to a bath 30 as the required quantity of water to be added. On the other hand, when the water in the bath is circulated, reheating is allowed. Therefore, reheating is started once.  Then, the quantity of remaining water in the bath 30 is calculated after reheating and hot water is additionally supplied corresponding to the quantity of operation remaining water.

Firing is carried out at 460-900 deg.C. The compsn. produces a bright film on firing. The compsn. can opt. contain precious metal powder or insoluble precious metal cpd. to produce a burnished film on firing which is subsequently burnished. Alternatively, the compsn. opt. contains an insol. matting agent to produce a self-burnishing film on firing.

IPC: H02M1/08
Filed: 1978-10-07
Abstract: PURPOSE: To prevent the trigger circuit of a thyristor from effect of qualities of the components by constituting a circuit so that a diode may be connected between the anode and the cathode of an N-gate thyristor, the conductive state of the diode may be ckecked at the maximum of the power voltage and then the main circuit may be turned on.  
     CONSTITUTION: The power voltage divided by a partial pressure circuit 100 is applied to the anode terminal of an N-gate thrystor 4 through the gate terminal of the N-gate thyristor 4 and a diode 8 until the power voltage takes the maximum. At the same time a condenser 6 also is charged on the same potential as the anode potential of the N-gate thyristor 4. The instant that the power voltage has taken the maximum phase, by this condenser, the diode 8 is switched over from a conductive state to a stopping one, then the N-gate thyristor 4 is put into a conductive state and trigger signals of a thyristor 3 are produced from a combined circuit 200 connected with the thyristor 4. Thus, it is possible to prevent the dispersion of trigger phases due to the dispersion of qualities of the circuit components.
