Title: Production of oxide superconductor
Inventor: SATO KENICHI
IPC: B28B1/00
Filed: 1990-04-18
Abstract: PURPOSE:To improve critical current density particularly in magnetic field and contrive the uniformalizing of a superconducting characteristic by a method wherein the method of milling is used in the step of mixing and, in the step of pulverization, a specific average particle size is obtained. CONSTITUTION:The materials such as oxide and carbonate are mixed together by means of milling to form an oxide superconductor. This mixture is treated with heat a plurality of times and a pulverization is effected after each heat treatment. In the heat treatment, the optimum temperature for the heat treating atmosphere is selected. To reduce the partial oxygen pressure in the heat treating atmosphere, the temperature is made somewhat lower than normal. By the above-mentioned pulverizations, the materials are reduced to the powder having an average particle size of not more than one micron in diameter. It is preferable to use a ball mill or attriter to reduce the same to the powder having an average particle size of submicron with the maximum particle size of two microns. The adjustment of the particle size in this way, coupled with a uniform mixing, permits the non-superconducting phase inevitably produced to be finely dispersed and a uniform superconducting characteristic to be obtained.

Title: Method and apparatus for washing coating device
Inventor: SATOU MAKOTO
IPC: B05B5/08
Filed: 1980-07-31
Abstract: PURPOSE: To accomplish high-speed washing without damaging a coater by providing a valve for switching a flow of a washing liquid between the discharge side and the coater side, in washing a coating device at the time of changing the color of coating material.  
     CONSTITUTION: When washing the coating device, firstly a change-over valve 7 is opened to the discharge side and a pipe 6 on the upstream side is washed at high pressure and at high speed. Then, the valve 7 is changed over to the coater 4 side, followed by washing at lower pressure and at lower speed. The change-over valve 7 has tandem construction consisting of needle-type valves 8, 9 such that no stagnation of fluid occurs in a fluid passage, and the valve 7 is operated pneumatically. Accordingly, the pipe 6 can be washed in a short period of time without causing waste liquid to be spattered. When subsequently washing the coater 4 side, since this side acounts for only a part of the system volume, the washing can be completed in a short period of time with a low washing speed and without causing damages on the coater 4 or extreme spattering of the waste liquid.

Title: Lead-acid battery charging method
Inventor: SHIOMI MASAAKI
IPC: H02J7/02
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To improve the Wh efficiency of charging without lowering the capacity of a battery by executing charging different from periodical charging, for every predetermined integrated discharged quantity of electricity. SOLUTION: Leveling charging is executed every time the integrated discharged quantity of electricity is five times or more the rated capacity of a battery. In a sealed storage battery, leveling charging is executed every time the integrated discharged quantity of electricity is five times or more the five- hour rate capacity of the battery. The discharged quantity of electricity of a lead-acid battery is integrated each time by an integrator or the like, and leveling charging is executed manually or automatically when the value is five to ten times the capacity of the battery. Since leveling charge can be executed neither more nor less compared to a system of periodically executing leveling charging regardless of the discharged quantity each time, the Wh efficiency of charging is high, and the lead-acid battery can be used without lowering the capacity. It is preferable that the integrated quantity of electricity does not exceed fifteen times the capacity of the battery. If the selected value is too large, the battery is undercharged and may cause lowering of the capacity.

Title: Voltage detector
Inventor: YAMADA ATSUSHI
IPC: G01R19/165
Filed: 1986-05-09
Abstract: PURPOSE:To suppress the oscillation phenomenon of a voltage detector by inserting a constant current circuit into the CMOS inverter of the output part of the detector and stopping a through current from flowing. CONSTITUTION:When an input voltage VIN is applied between terminals 7 and 8, a reference voltage VREF is developed at the output point A of a reference voltage generating circuit 1. The resistance divided voltage VB of the voltage VIN is generated at the connection point B between resistances 2 and 3 and the voltages VREF and VB are inputted to a comparator 4, thereby outputting a VSS level to an output point C when VB>VREF or a VDD level when VB<VREF. When a detection voltage with which the output of the comparator 4 is inverted is VDET, the VDD level is outputted to a voltage detection signal output terminal 9 when VIN>VDET and the VSS level is outputted when VIN<VDET. For the purpose, high impedance is interposed between a power source and the voltage detector and the voltage drop by the impedance is set to a voltage value which does not exceeds the hysteresis width of the detection voltage VDET of the comparator, so that oscillations due to an excessive through current are suppressed.
