Title: Collecting method of silver from electrolytic slime
Inventor: IIO TOSHIMASA
IPC: C22B11/00
Filed: 1981-04-22
Abstract: PURPOSE: To easily collect silver as a solution with high yield, by treating an electrolytic slime intermediate treatment substance containing lead which has become sulfate or a chloride, and silver which has become a chloride, by a mixing liquid of thiosulfate and sulfite.  
     CONSTITUTION: An electrolytic slime is brought to pre-treatment by a well- known method so that lead and silver become sulfate and/or a chloride, and a chloride, respectively. This electrolytic slime intermediate treatment substance is treated by a mixing solution of thiosulfate and sulfite, effluence of lead is suppressed, and silver is made to flow out. In this regard, against 0.5mol/l of concentration of thiosulfate, concentration of sulfite is set to about 0.01mol/l or more, practically about 0.1mol/l. The reaction is executed at a normal temperature, and as for a liquid from which silver has flowed out, the residue is separated and removed, and silver powder is collected by means of electrolysis, etc.

Abstract: PURPOSE:To perform the measurement of the recovery time of a TR tube as packaged at any time by monitoring and judging changes in the gain control voltage with respect to the delay time when a false target is tracked by operating a gain control circuit with a signal processing section. CONSTITUTION:A trigger signal A generated synchronizing a high frequency/high power signal generated from a transmitter 5 is received with a signal processing section 8, which controls a false target signal generation circuit 4 so as to generate a high frequency false target signal B of a fixed level delayed by a certain time therefrom. This signal B is inputted into a receiver 6 through a TR tube 3 recovered from a loop coupler 2 and an output signal C is controlled with a gain control circuit 7 to track the distance of a target through a tracking section 10. Therefore, control is performed with a processing section 8 to change the delay time maintaining the signal B at a fixed level and the delay time when the output signal D of the circuit 7 lowers by a fixed value from the initial value is outputted to a display section 9 thereby enabling the measurement of the recovery time of the TR tube 3.

Title: Transformer for rectifier
Inventor: SOKAI KATSUJI
IPC: H01F27/40
Filed: 1987-03-19
Abstract: PURPOSE:To simplify the composition of a circuit, by balancing the DC winding current of two sets of DC winding groups flowing on the primary side of an interphase reactor (IPR), with circulating current flowing to the secondary winding of the IPR. CONSTITUTION:So far as a rectifier 20 having a transformer 10a for the rectifier is concerned, at the time of commutation from a phase n to a y phase for example, on the sides of the primary windings 51a, 51b of an IPR 50, current burdening full-load current flows. In the meantime, on the sides of the secondary windings 52a, 52b of the phase u and phase y of the IPR 50, current corresponding with the ampere turn (AT) of the windings 51a, 51b flows as circulating current I2. In this case, when the load current of the IPR 50 of the phase u is made greater than that of the phase y, then on the side of the winding 52a of the IPR 50 of the phase u, more current increased by component corresponding with the AT flows. However, the winding 52a of the phase u is set in a state that it is series-connected to the winding 52b of the phase y, to compose a closed circuit, and so increased current flows also into the winding 52b of the phase y and works to increase the partial charge of load current. As a result, to the phase u and the phase y, the load current is to flow half by half.

Abstract: PURPOSE:To enable immediate switching upon malfunction of a fan by juxtaposing two cooling fans and providing a switch for switching respective motors between a drive power feeder and an electromotive force detector and an alarm processor for switching based on an output from the electromotive force detector. CONSTITUTION:Upon droppage of wind force due to malfunction of a cooling fan F11, electromotive force of a cooling fan F12 drops. When the electromotive force drops below a predetermined level, an electromotive force detector E provides a signal to an alarm processor A. Consequently, a switch S1 is switched through the alarm processor A based on the signal to disconnect the motor of the cooling fan F11 from the power feeder and connect the motor to the electromotive force detector E. On the other hand, the motor of the cooling fan F12 is disconnected from the electromotive force detector E and connected to the power feeder. Consequently, the cooling fan F12 is driven and the cooling fan F11 serves as a rotary detector.
