Title: Electromagnetic coil driving circuit
Inventor: NAKAMURA TAKASHI
IPC: H01F7/18
Filed: 1982-03-25
Abstract: PURPOSE:To reduce sharply heat generation of a resistor, and moreover to form the driving circuit in a small type by a method wherein a switching element to be driven to ON state when the electromagnetic coil is in the operating condition is made as to be connected in parallel with a time-regulated resistor. CONSTITUTION:The transistor TR2 to be driven to ON state when a solenoid driving signal SS is in the L level, and the electromagnetic coil 18 is in the operating condition, is connected in parallel with the resistor R1. Accordingly, the counter-electromotive force to be generated in the coil 18 when the electromagnetic coil 18 is in the operating condition is absorbed in the switching transistor TR2 side, and consumption of electric power is not generated in the resistor R1. A current generated in the coil 18 according to counter-electromotive force flows to the resistor R1 only when the coil 18 is made to return to the non-operating condition. Accordingly, by limiting flow of the current in the resistor only to returning time of the electromagnetic coil to the non-operating condition, calorific amount of the resistor can be reduced sharply, and the driving circuit can be formed in the small type.

Abstract: PURPOSE:To estimate the combustion zone front position of the coke in a sintering raw material and controlling the sintering reaction therefrom in the stage of producing sintered ore with a DL type sintering machine by measuring the air flow distribution in the longitudinal direction of a pallet and the moisture in combustion gas and integrating the evaporating moisture from the ignition position of the raw material thereto. CONSTITUTION:A raw material layer 5 for sintered ore on a pallet 4 of a DL type sintering machine is ignited by an ignition furnace 6 and a combustion gas is sucked by an exhauster 10 from a wind box 9 in the lower part to sinter the raw material. Moisture analyzers and air flowmeters are provided to the many wind boxes 9 in the longitudinal direction of the pallet 4 and the amt. and moisture of the waste combustion gas in each wind box are measured. The moisture flow rate per hour of each box 9 is determined from the product of the amt. of the waste gas and the moisture contained therein. The ratio between the moisture flow rate over the entire part and the total of the moisture flow rate from the first wind box up to the specific wind box is calculated by a calculator and the combustion zone front position in the sintering raw material is indicated on a CRT. The sintering condition is thus detected with good accuracy and the adjustment of the sintering operation to the finest state from said position is made possible.

Title: Motor controller
Inventor: SUDO MASAYASU
IPC: H02P27/06
Filed: 1994-03-18
Abstract: PURPOSE:To reduce vibrations caused by the difference between a generated torque and a load torque by a method wherein a fluctuation in the load torque is computed on the basis of information on a rotational position during one rotation of a rotor and a current and a torque are controlled. CONSTITUTION:A control part 20 computes the magnitude and the time of a load torque, during one rotation, which is applied to a compressor 13 on the basis of a positional signal, and it sends to a power-supply drive part 21 a signal which makes the output torque of a motor coincide with the detected load torque. The power-supply drive part 21 receives the signal. When the output torque is small, the drive part acts so as to increase a supply voltage to the motor and, when the output torque is large, the drive party acts so as to lower the supply voltage to the motor. Thereby, the output torque of the motor becomes nearly equal to the load torque which is changed during one rotation, a fluctuation in the rotational speed of a rotor due too a fluctuation in the load torque is eliminated, and vibrations are reduced.
