Inventor: TANABE MASAO
IPC: C21D11/00
Filed: 1989-10-03
Abstract: PURPOSE:To obtain good controllability with the capacity and power consumption of a controller for a small circulating fan and driving motor by making use of the advantages in the case of the pressure control of nozzles with the opening degree of a circulating damper and the rotating speed of the circulating fan. CONSTITUTION:The opening degree of the circulating damper 9 is gradually reduced by as much as the amt. required to causing a pressure change by the difference in the pressure PN required for the strips A and B at the timing before the juncture of the two strips advance into the corresponding zone in a treating furnace when the required nozzle pressure PN to the succeeding strip B is larger than that to the preceding strip A. The rotating speed of the circulating fan 7 is simultaneously increased to maintain the specified pressure PN and thereafter, the opening degree of the damper is reduced to rapidly restore the previous state at the timing when the juncture advances into the zone 1. On the other hand, the damper is rapidly throttled down to change the required pressure PN to the strip B at the timing at which the juncture advances into the zone 1 and thereafter, the opening degree of the damper is rapidly reduced to restore the state before the throttling when the required pressure PN to the strip B is smaller than that to the strip A. The rotating speed of the fan is thereafter gradually lowered to maintain the present pressure PN constant.

Filed: 1993-09-08
Abstract: PURPOSE:To obtain a sufficient cooling effect without using a large cooling apparatus by a method wherein treated water is cooled by an electronic cooling unit and a radiator of the electronic cooling unit is cooled by water from a water source. CONSTITUTION:An electronic cooling unit 100 has a radiator 102 with a number of fins 100 and the radiator 102 is located on an acid water path stretching from an acid water outlet 16.

Abstract: PURPOSE:To execute the action of an erasing code without fail by neglecting an erasing code reproduced by the detecting output and an index signal reproduced for a prescribed period before or after the erasing code when the reproduction of the erasing code is detected. CONSTITUTION:At the time of the reproduction of a magnetic tape, the output of a decoder 86 is supplied to a detecting circuit 91, and it is checked whether or not an erasing code IERS is included. When the code IERS is detected, the detecting output is supplied through a control circuit 92 to a checking circuit 87, an index signal CDIX latched in the circuit 87 is cleared and the CRC checking of a prescribed period circuit 87 is prohibited. Consequently, only when the code IERS is not recorded, the signal CDIX is removed from the circuit 87, and when the code IERS is obtained and the signal CDIX is obtained before and after it, they are neglected and not outputted from the circuit 87. Thus, the action of the erasing code can be executed without fail.
