摘要： In a self-oscillating type switching power supply in which an input source, a primary winding of a transformer, and a switching element are connected in series, and a constant output is supplied to a load from a secondary winding of the transformer by the operation of the switching element, in order to obtain a signal to turn off the switching element, a sense circuit for detecting the output of the switching power supply is provided, and the analog signal from the sense circuit is inputted to one winding of a saturable reactor, and at a time point when the switching element is to be turned off, the analog input signal is converted into a pulse signal insulated from the analog input signal, and the pulse signal is outputted from another winding of the saturable reactor. By such a system, a switching power supply having a very simple circuit arrangement and high output voltage precision can be achieved.

摘要： The piston actuator for a governor valve in a carburetor is coupled through an electromagnetically operable selector valve to either atmospheric pressure in the air filter or to vacuum in an intake manifold. The selector valve is controlled by engine speed detected by speed detecting means, and by a switch controlled by the accelerator linkage to close a circuit whenever the accelerator pedal is depressed to within a range bordering maximum depression. When the accelerator pedal is depressed to within the above range, and engine speed is below a predetermined value, the selector valve connects to the manifold to interrupt operation of the governor valve. Operation of the governor valve resumes when the speed reaches the preset value or the accelerator pedal leaves said range.
