Title: Device for driving stepping motor
Inventor: MOHAMEDO MOKUDATSUDO
IPC: G04C3/14
Filed: 1985-02-28
Abstract: The device enables a stepping motor (M) to be supplied at constant power whatever the value of the supply voltage. Using a bridge (R1 to R4), a voltage (UAB) proportional to the supply voltage (U0) is tapped. The signal (T1) required to advance the rotor by one step is split into a large number of sampling periods (Te) of predetermined duration. Each of these periods consists of an elementary pulse followed by a period of interruption. The duration (T0) of the elementary pulse is determined by the time taken by a capacitor (C) to become charged: this will become shorter as the proportional voltage (UAB) applied to terminals of a network (RC) becomes higher. A comparator (16) compares the voltage (Uc) across the terminals of the capacitor with a reference voltage (Ur) so as to determine the duration (T0) of the elementary pulse and to define a chopping rate for the supply signal to the motor (M) which is inversely proportional to the supply voltage (U0). <IMAGE>

Filed: 1994-03-11
Abstract: PURPOSE:To lower the thermal withstanding capacity of a resistor in a DC overvoltage suppressing circuit by delivering a gate ON signal to all turn OFF thyristors upon occurrence of short circuit failure in any one of them. CONSTITUTION:Upon failure of a turn OFF thyristor (GTO) 7-1 in a DC overvoltage suppressing circuit 4, for example, it is detected by a voltage detector 8-1 and a failure detector 11 for the element and a gate ON signal is delivered to all GTOs 7-1,..., 7-4 which are thereby turned ON. Since the energy stored in a capacitor 3 is shunted to resistors 6-1,..., 6-4 connected in series with the GTOs 7-1,...,7-4 in the DC overvoltage suppressing circuit 4, the energy which must be consumed by one resistor is reduced by a factor of four as compared with the energy stored in the capacitor. Consequently, the thermal withstanding capacity of the resistor 6 in the circuit 4 can be reduced.

Title: Valve control circuit in combustion apparatus
Inventor: KONUMA MASAMI
IPC: F23N5/24
Filed: 1989-02-23
Abstract: PURPOSE:To prevent backfires by introducing a mechanism wherein a circuit functioning to drive a first current-control device differentiates by a differentiating circuit containing a capacitance a signal permitting the opening of a valve and, according to the differentiated outputs, causes the first current-control device to supply an attraction coil with an energizing current. CONSTITUTION:A drive circuit 14 for actuating a first current-control device 11 differentiates by a differentiating circuit 17 containing a capacitance a valve- opening-permitting signal VE permitting the opening of a solenoid valve 10 and, according to the differentiated outputs, causes the first current-control device 11 to supply an attraction coil GV with an attraction current IG. The capacitor in the differentiating circuit 17 is designated to releases a charge at a specified time constant when a valve-opening-permitting signal VE is not inputted. Therefore, even when signals VE are successively inputted during a short time, it does not occur for the differentiating circuit 17 to issue differentiated outputs on the basis of signals VE inputted for the second time and thereafter before sufficient release of the charge from the capacitor in the differentiating circuit 17. The valve is prevented from being turned on and off successively and hence backfires is prevented from occurring.
