摘要： A drive circuit for a solenoid pump comprises a series combination of a pump solenoid and a capacitor connected through a rectifier circuit with an a.c. source. The solenoid is shunted by another rectifier poled to pass a charging current to the capacitor. A thyristor is connected across the series combination, and is triggered into conduction, whereupon it short-circuits the series combination to permit a discharge of the capacitor through the solenoid and to prevent a current flow from the source to the capacitor, thus allowing a uniform control of the energy discharged by the capacitor. A trigger circuit for the thyristor comprises a relaxation oscillator including a programmable unijunction transistor, the conduction of which is controlled inversely to fluctuations in the source voltage.

摘要： A load current control device operates so as to control the magnitude of a current delivered to a load by varying a duty factor. With this control device, a fundamental value is determined on the basis of an instruction of an input signal, and a reference duty factor and a reference current value are determined on the basis of the fundamental value. The control device further operates to correct the reference duty factor on the basis of a difference between the magnitude of a current actually flowing in the load and the reference current value to turn on and off a power supplied in accordance with the corrected duty factor, therby to control the magnitude of the load current. In addition, when the above-said difference is out of a predetermined range, this load current control device outputs a signal indicative of abnormal condition.

摘要： In an electro-mechanical converter of the type wherein a plunger contained in a cylinder is moved in the axial direction thereof by passing a control signal through a solenoid coil wound about the cylinder, the diameter of the plunger is made sufficiently smaller than the inner diameter of the cylinder such that the plunger can move without causing undue friction. The plunger is supported by ball bearings to be movable with respect to the cylinder. To control a power steering unit of a motor car a control valve is actuated by the plunger for controlling the amount or pressure of the operating oil supplied to the power steering unit, in which case the control signal is made to be proportional to the speed of the motor car.
