Title: Automatic control device for boiler
Inventor: SATO NAOYUKI
IPC: F22B35/00
Filed: 1988-02-22
Abstract: PURPOSE:To improve the responsive property as well as the stability of a control system, by a method wherein a filter circuit, having less time delay in a measuring signal and following sensibly in addition to the securing of a stability in control as well as the improvement in the endurance of an operating terminal, is employed in the title device. CONSTITUTION:A signal, outputted from a pulsation removing dynamic filter 101, is used as an amount to be controlled. At first, primary delay operation A is effected with respect to a measuring signal 1 whereby the high ripple of pulsation is removed. Subsequently, the primary delay operation B is effected again with respect to a signal 2, in which the high ripple is removed, whereby the low ripple of the pulsation is smoothed. Next, a difference 4 between the signal 2 and the signal 3 is passed through a function generator C, in which a blind sector is set, whereby a signal 5, in which the pulsation of a sudden and remarkable fluctuation of the measuring signal 1 is removed, is produced. Finally, the signal 3 is added to the signal 5 whereby a filter output signal 6 produces a true value, in which the pulsation is removed, with respect to the measuring signal.

Filed: 1981-03-18
Abstract: PURPOSE:To control wire size by exchanging a cheap and easily exchangeable, drawing die by performing a drawing work at least once after peeling, in the  manufacturing process of a flat square wire. CONSTITUTION:Roughly drawn wire 1 is supplied from a supplier 12 continuously, and is fed into a wire drawing mill 16 through a guide-wheel and drawn.

Filed: 1985-02-27
Abstract: PURPOSE:To obtain an optimum segregated charging state of raw material by disposing a roller shute having slits so as to incline between a roll feeder in the lower part of an ore feed hopper and pallet and rotating a roller group. CONSTITUTION:The roller chute 3 having slits of <=15mm opening interval is installed so as to incline at 45 deg. with the horizontal plane between the roll feeder 2 in the lower part of the ore feed hopper 1 and the pallet 4 of a sintering machine.

Abstract: PURPOSE:To obtain a magnetic recording disk for read margin check, which can reduce a reading voltage, by constituting a data field of a data pattern to change a rate between a recorded range and an erased range concerning the width direction of a track in each sector. CONSTITUTION:For the magnetic pattern to be formed in the track of a floppy disk, an interval between ID fields for recognition, which are provided in the length-wise direction of the track with a constant interval, is a sector 22 and a data field 23 is formed in this sector 22.

Title: Error preventing circuit for voltage measurement
Inventor: TERU KATSUYOSHI
IPC: G01R19/25
Filed: 1987-02-20
Abstract: PURPOSE:To speed up measuring operation by removing an error in measured voltage due to equivalent stray capacity which is present on the side of the input bus of an A/D converter by a discharging circuit. CONSTITUTION:The discharging circuit 7 is constituted by interposing the series circuit of a resistance R and a relay contact point rs between the ground and a bus 10 connected from a multiplexer MPX to a DC measuring instrument DCM closely to the input terminal 9 of the A/D converter of the bus 10. Then a driving pulse Ps with a period T is applied to the contact point rs at the time of voltage measurement, and consequently the contact point rs is turned on to set the voltage at the terminal 9 to a zero state temporarily. Then the voltage V1 of a measurement object point 11 is inputted to the A/D converter. Even when a voltage V2 at a next measurement object point 12 is inputted to the A/D converter, the contact point rs is turned on with the pulse Ps before the voltage V2 is measured to clear the remaining voltage at the time of the voltage V1 to a zero state temporarily, and a DC voltage is inputted to the measuring instrument DCM. Namely, the contact point rs is operated associatively with the switching of switches RS1-RSN of the multiplexer MPX to clear remaining charges due to the stray capacity of the bus 10.
