Patent JP-S62268171-A (JP)
Title: Semiconduction functional device
Inventor: OSHIMA TOSHIO
IPC: H01L29/86
Filed: 1986-05-16
Abstract: PURPOSE:To obtain the desired characteristics of a negative resistance element by forming a superlattice in which semiconductors having different energy difference in upper troughs and lower troughs are laminated alternately at a plurality of periods. CONSTITUTION:When an electric field (Z direction) applied to a superlattice is comparatively small, the electrons of a conduction band receive phonon scattering and pass in troughs R without transferring to upper troughs L while properly losing energy and being accelerated by the electric field. Consequently, the superlattice functions as only an electric resistance region with phonon scattering, and displays characteristics in which currents increase by the augmentation of the electric field. When the electric field applied to the superlattice is magnified, the rate where the electric field is accelerated is enlarged, energy is lost insufficiently only by phonon scattering, and electrons receive scattering at points L in the upper troughs when they enter semiconductor layers II in superlattices having the low points R. Since the discontinuity of bands exist in the upper troughs, however, electrons cannot transfer. Accordingly, a semiconductor element displaying desired two-terminal negative resistance characteristics can be acquired.

Title: Dc magnetization preventing circuit for inverter output transformer
Inventor: TANAKA SABURO
IPC: H02M7/537
Filed: 1990-04-26
Abstract: PURPOSE:To prevent DC magnetization or saturation of the core of an output transformer by detecting DC component in the output from a switching circuit and then varying zero potential of a modulation signal based on an output from a DC magnetization detector for producing a DC voltage proportional to thus detected DC component thereby suppressing DC component in the output from the switching circuit. CONSTITUTION:Output current from a switching circuit 3 detected through an output current detector 14-1 is an AC sine wave current containing ripple having frequency of a carrier signal, i.e., a triangular wave es. When the time constant of a resistor R1 and a capacitor C1 in an integrating circuit 14-2 is set larger than the period of the sine wave, charges corresponding to the DC component in the output current are stored in the C1 and a DC voltage proportional to the DC component is fed to an impedance converter 14-3. Consequently, output from the converter 14-3 is inverted and added, in an adder 15, to the sine wave modulation signal es in order to vary zero potential of the sine wave es thus suppressing the DC component in the output from the circuit 3. Consequently, DC magnetization or saturation of the core of an output transformer is prevented resulting in prevention of breakdown of a switching element due to overcurrent.
