A terminal cylinder 5 of the anode 9 is connected to the positive electrode of a DC power source and the work C is connected to the negative electrode 17. The anode 9 is rotated around a conductor shaft 2 as the rotation of a worm gear B by a motor A is transmitted to a rotating gear 3. The Ni electrolyte fed in a liquid feed pipe 11 running through the inside of the anode 9 is released from a lower outlet 10 thereof to form an Ni electrocasting layer on the inside surface of the work cathode C and is discharged from a liquid discharge port 13 provided to the barrier wall 12 at the top end face of the work C, by which the electrolyte is circulated. The inside surface D to be treated is thereby electrocast at an extremely high speed.

Title: Control method of hot water tank
Inventor: MIZUNO NAOKI
IPC: E03D9/08
Filed: 1994-07-15
Abstract: PURPOSE:To prevent a heater from being unrestrictedly energized when water flows out of a hot water tank. CONSTITUTION:When a flush switch 32 is turned ON, hot water in a hot water tank 16 is supplied to a flush nozzle 28 by way of a pump 22 and a solenoid valve 24. City water flows into the tank 16 in place of the hot water. The amount of water which has flown into the hot water tank 16 is determined from the ON time of the flush switch 32 and a selection signal of a flush intensity adjusting switch 34. In addition to that, the difference between a target water temperature and an in-flow water temperature is determined from a selection signal of a water temperature adjusting switch 36 and a detection signal of a water supply temperature sensor 14. Based on the amount of the in-flow water and the differential water temperature, the amount of electric power to be supplied to a heater 20 is computed. In case when the amount of power, which is factually supplied to the heater, exceeds the amount of power supplied more than specified, the power supply to the heater 20 will be halted.

Title: Exciting apparatus for sychronous machine
Inventor: TAKAGI KOUZOU
IPC: H02P9/08
Filed: 1979-12-18
Abstract: PURPOSE:To avoid the generation of the abnormal voltage in a field winding in switching an exciting power supply from an in-house AC power source to an output AC power source, by locking an igniting signal to each control rectifying element of an exciting rectifier, and actuating a paired igniting circuit for a specific phase. CONSTITUTION:In the case the voltage of a generator 1 is established, the in-house AC power source 4 is applied to a thyristor rectifier 6. When the voltage of the generator 1 becomes a specified voltage, the thyristor igniting pulse signal of a voltage regulator 7 is locked, and a paired U-shaped igniting circuit 11 is operated. The paired U-shaped igniting circuit 11 gives the igniting pulse signal to the thyristor which is connected to the positive side or negative side of the DC of the U phase when the potential of the U phase is higher or lower than the potentials of any other phases. After the paired U-shaped igniting circuit 11 has been actuated, breakers 3 are opened and breakers 12 are closed. Thereafter, the igniting pulse signal is unlocked.
