Title: Resonance type coil driving circuit
Inventor: TAKAHASHI KOUJI
IPC: G11C11/14
Filed: 1982-11-26
Abstract: PURPOSE:To supply a sinusoidal current having a prescribed amplitude to a resonance coil at all times with simple constitution by controlling the Q of the resonance circuit via a control transistor (TR) in response to a current flowing to the resonance coil. CONSTITUTION:A series resonance circuit formed by a capacitor 2 and a coil 1 of a resonance type coil driving circuit for rotating magnetic field generation of a magnetic bubble memory element is driven by a DC power supply 5, and P and N type switching TRs 3, 4. The current flowing to the coil 1 is smoothed by a diode 6 and a capacitor 7, a voltage corresponding to the current flowing to the coil 1 via voltage dividing resistors 8, 9 is generated and impressed to a gate of the control TR11. Then, if the coil current is decreased because of voltage fluctuation of the power supply 5 and variation in the characteristics of the TRs 3, 4, a gate-source voltage of the TR11 is reduced and the drain current is decreased, the Q of the resonance circuit is large, and then the coil current is corrected into a prescribed value. This is the same as the case with the increased coil current, the sinusoidal current having a prescribed amplitude is applied always to the resonance coil with simple constitution.

Abstract: PURPOSE:To prevent the lowering of damp-proofing due to the mounting of a substrate by forming a molding section to a chevron on viewing from a plane, shaping a pair of fitting holes near the top of a hillock and leading out a plurality of leads from the direction opposite to the top of the hillock. CONSTITUTION:A semiconductor element 15 is mounted to a section slightly lower than the center of a header 11, each electrode is connected at one tips of wires 16, and the other tips of the wires 16 are connected at the inner ends of leads 17. A molding section 19 covers the semiconductor element 15, the wires 16 and the inner end sections of the leads 17, and takes a Conidae-shaped chevron, a top section thereof extends between a pair of fitting holes 12, and skirt sections thereof stretch along sections in the vicinity of the fitting holes 12. Since the molding section 19 is extended deeply between the fitting holes, a distance l2 between the periphery of the semiconductor element 15 and a nearest molding-section periphery is made longer than a distance l1 in conventional structure. Accordingly, the intruding path of moisture from a boundary between the header 11 and the molding section 19 is lengthened, thus improving damp-proofing.
