Title: Apparatus for recovering heat of flash steam
Inventor: MITSUOKA EIICHI
IPC: F28D21/00
Filed: 1979-03-22
Abstract: PURPOSE: To enhance the waste-heat recovering efficiency to a great extent, by providing an ejector so that water condensed in a heat exchanger can be returned to a flash tank with ease.  
     CONSTITUTION: When high-pressure drain is returned from paper-manufacturing drier 11 via outlet port 3 into flash tank 3, a portion of drain is re-vaporized into steam. Since temperature of the steam is as high as about 100°C, it is passed through heat exchanger 6 and conduit 4 for recovering heat and returning as drain to flash tank 3 or to a water supply tank. On the other hand, air or water heated by cooling the steam is carried through conduit 21 so that it is used separately as heating fluid. By passing a portion of the air or water carried to heat exchanger 6 to ejector 16 via bypass pipe 13, partial vacuum is developed in pipe 17 and hence at the outlet of heat exchanger 6, so that drain can be smoothly passed through heat exchanger 6. Thus, heat can be released and absorved by the fluid to be heated highly efficiently.

Title: Output voltage control method
Inventor: TANAKA KAZUHIKO
IPC: H02J1/00
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent an output voltage from overshooting on hunting even when a startup speed is fast by applying a small bias value as an output voltage setting signal after an on command and increasing the output voltage setting signal to a set voltage level after an output voltage detection signal becomes stable. SOLUTION: An output voltage setting signal is made a low bias level VVIAS for a fixed time after an on command and the signal VREF is increased up to a prescribed value after a grid voltage rises, a vacuum tube becomes slightly conductive and a load voltage rises. Thus, an error is prevented from being excessive. An error is prevented from reaching the level VBIAS or more even after the on command. That is the grid voltage rises slowly and when a plate current starts to flow, the grid voltage is also prevented from rising too high. Then, the load voltage is prevented from overshooting or hunting.
