IPC: H03K21/40
Filed: 1978-11-13
Abstract: PURPOSE:To avoid the malfunction of the counter due to the erroneous signal of the service interruption time by providing the 2-series rectifier circuits connected to the AC power source plus the constant voltage circuit and thus securing the different value for the fall of the power source at the service interruption time as well as accelerating the voltage fall of the power circuit to be applied to the counter circuit. CONSTITUTION:The power circuits of the 2-series consisting of rectifier circuits 231 and 232 plus constant voltage circuits 251 and 252 are connected to the secondary side of transformer 22 connected to AC power source AC. And the discharge time of output voltage E2 caused by circuits 232 and 252 of one side and at the service interruption time is made shorter than output voltage E1 caused by circuits 231 and 251 of the other side. Voltage E2 featuring the shorter discharge time is supplied to the counter main body, and voltage E1 featuring the longer discharge time is supplied to electronic unit 26 which supplies the input signal to the counter main body. Thus the power voltage to be supplied to the counter main body is stopped quickly at the service interruption time. In such way, the counter malfunction due to the input signal can be prevented.

Title: Constant low voltage circuit
Inventor: HASHIMOTO MASAMI
IPC: G05F3/24
Filed: 1981-09-04
Abstract: PURPOSE:To decrease the number of components and to reduce pattern area by obtaining the difference between threshold voltages of two N type MOSFETs as an output voltage, and deciding on the beta of the MOSFETs on the assumption that load currents are supplied from their output terminals. CONSTITUTION:This circuit consists of two P type MOSFETs 21 and 22 having the same threshold voltage and two N type MOSFETs 23 and 24 differing in threshold voltage. In this case, the FETs 21 and 22 both operate in a saturation region and their gates are connected in common, so the ratio of currents flowing through the FETs 21 and 22 is equal to the ratio of betar1 and betar2. Further, currents flowing through the FETs 21 and 23 are equal. Namely, the potential of an output terminal 25 relates to all of the FETs 21, 22, 23, and 24, and as the threshold voltage of the FET23 is higher and higher, the currents flowing through the FETs 21 and 23 are less and less the current flowing through the FET22 is also less and less; as the current flowing through the FET22 is less and less, the potential of the terminal 25 approximates a -Vss more and more.

Title: Motor control circuit
Inventor: NAGATA KUNIO
IPC: H02P7/29
Filed: 1989-05-31
Abstract: PURPOSE:To simplify a circuit constitution and to decrease cost by enabling a rotation control equivalent to a stepless speed variation despite two step speed variation of high and low. CONSTITUTION:An amplifier 20 compares the potentials of a voltage taken by resistance R6 and an oscillation voltage from a comparator 18 and controls the potential of two end points with the increase of the voltage across the ends of said resistance R6 to lengthen the time of charging of a capacitor C1 and change the oscillation time constant of said comparator 18 with the increase of a motor current. Consequently, a switching circuit 17 switches an output element 14 by a high pulse duty with the increase of ON time. Therefore, when a load of motor M rises from a low-speed rotating state, the control current of said motor M is increased automatically to raise a motor torque so that it is possible to obtain a similar control state just equivalent to a stepless speed variation.

Title: Swing arm type magnetic head driving device
Inventor: KUNO HIROYUKI
IPC: G11B21/02
Filed: 1981-09-08
Abstract: PURPOSE:To prevent oscillation by moving an outer wheel of the bearing inserted to either one end of the rotary shaft to thrust direction in a supporter, and providing a pre-pressurizing to the outer wheel to the thrust direction, consequently increasing natural oscillation of the bearing part of a rotary shaft. CONSTITUTION:When an outer wheel is pressed downward with a compressing coil spring 11, a radial partial pressure and clearance produced in bearings 5a and 5b are kept constant. When a thrust weight is exerted to a rotary shaft 1, the outer wheel of the upper bearing 5a is suitably moved in the thrust direction and the weight is absorbed by the spring 11 depressing the outer wheel of the bearing 5a. Thus, the radial partial pressure and clearance of the bearings 5a and 5b are kept constant, allowing to increase the specific oscillation of the bearings 5a and 5b inserted to both ends 4a and 4b of the rotary shaft 1.
