Abstract: Disclosed in a high-performance electromagnetic pickup cartridge with little distortion, comprising a stylus attached to the end of a cantilevered arm, a disk type armature magnetized in its axial direction and secured to the arm, and bar type magnetic core elements disposed in the vicinity of the armature so that they are at right angles to the axis of the cantilevered arm and correspond to each channel of a stereophonic record. When the armature is vibrated, an output signal is generated in respective coils wound around the core elements. Because of the above-described construction, the core elements need only have a bar-shaped configuration without the necessity for opposing faces between which a magnet or an iron piece would otherwise have to be inserted.

Abstract: A switching power source circuit intermittently switches a current at a primary winding of a transformer in accordance with the repeated switching of a bipolar transistor so as to rectify and smooth a voltage induced at a secondary winding of the transformer, thereby obtaining an output voltage. A capacitor is charged by a voltage induced by a feedback winding of the transformer. The base-emitter path of the bipolar transistor is reverse biased by this charge voltage so as to perform high-speed switching, so that a compact transformer and capacitor can be used and the switching power source circuit becomes low in cost.The application of the reverse bias voltage is performed by a transistor which is turned on when an emitter (grounded through a resistor) voltage of the bipolar transistor is increased to a predetermined level (threshold). A switching period of the bipolar transistor is determined by a period determining circuit consisting of a timing capacitor and a resistor.
