Title: Cooling water supplying apparatus
Inventor: MIYATA ITSURO
IPC: F28G9/00
Filed: 1988-09-09
Abstract: PURPOSE:To prevent impurities or organic materials from depositing in a valve and a cooler and to always supply sufficient cooling water to the cooler by periodically switching first and second automatic switching valves thereby to reversely feed cooling water during cooling. CONSTITUTION:When a feed water pump 1a is driven in a state that automatic switching valves 13a, 16a are opened and automatic switching valves 13b, 16b are closed, cooling water is supplied from a cooling water exit 8a into a cooler 8 through the valve 13a, and the water from a cooling water exit 8b is drained through the valve 16b. When a predetermined period of time is elapsed, the valves 13a, 16a are closed and the valves 13b, 16b are opened by a timer. Thus, the water discharged from the pump 1a is fed from the exit 8b to the cooler 8 through the valve 13b, discharged from the exit 8a, drained through the valve 16b, and periodically switched to be reversed. Thus, it prevents impurities from depositing in the cooler 8.

Title: Method and device for measuring side gap of gear pump
Inventor: OSAWA NORIYOSHI
IPC: F04C2/18
Filed: 1984-10-26
Abstract: PURPOSE:To facilitate the measurement of the side gap of a gear pump, by causing a gas of constant pressure at the discharge side of the pump to flow in as the pump is turned at a prescribed rotational frequency, and by measuring the side gap of the pump in terms of the pressure of the gas. CONSTITUTION:A pressurized gas of constant pressure is supplied to the discharge port 8 of the gear pump 1 through a feed pipe 13 as the pump is turned at a prescribed rotational frequency by a driver 10. The pressure in the feed pipe 13 is detected by a pressure sensor 17, the output of which is applied to a calculator 18 to compute the side gap S of the gear pump 1. The side gap S of the pump 1 can thus be very easily measured in a short time.

Title: Horizontal type electroplating cell
Inventor: HIROOKA YASUHIRO
IPC: C25D7/06
Filed: 1982-12-24
Abstract: PURPOSE:To perform satisfactory continuous plating at a high speed while improving the supply of metallic ion and discharging of produced gas in horizontal type electroplating wherein a strip is passed between insoluble anode plates placed oppositely to each other by disposing alternately inlet and outlet holes for passing an electrolyte on the anode surface. CONSTITUTION:A strip 1 fed into a plating cell 10 by a conductor roll 6 is electroplated when current is conducted between the roll 6 and anodes 2, 3. The electrolyte fed from a master tank is ejected from discharging holes 11 and is sucked out from suction holes 12 and a return piping 9 so as to return to the master tank. Since there is a sealing plate 8, the liquid flows by filling the electrolyzing space, by which metallic ion is thoroughly supplied and produced gas is satisfactorily discharged. A good plating layer is thus formed and a high speed operation is made possible.

Abstract: PURPOSE:To make it possible to perform phase control at the time of opening of a contact so as to eliminate dispersion of life time of the contact by magnetizing and demagnetizing an electromagnet through a driving circuit at a time when a wave form of electric powers supply which is to be applied to/or being applied to a contact is detected in form of a light signal and its compared with a reference value in a comparator circuit and as the result, it is found to be below the reference value. CONSTITUTION:A wave form of a power supply circuit is detected in form of a light signal by a photo coupler 12, and the detected value is compared with a reference value. And, when a signal which sets an electromagnetic relay 1 on/off is input, and at the memory when a detected value is less than the reference value as the result of comparation in comparator circuit 26, the electromagnetic relay 1 is set to on and off. Accordingly, until an instantaneous value of a load power 21a reaches a value less than a set voltage at the time of opening and closing of the electromagnetic relay 1, a movable contact 9 is not released from a fixed contact 11, thus arcing can be suppressed. In this way, optimum control can be performed at both closing and opening of a contact, also dispersion on life time of the contact of the electromagnetic relay 1 can be eliminated.
