Patent JP-H03245773-A (JP)
Title: Inverter device
Inventor: MAEHARA MINORU
IPC: H02M7/538
Filed: 1990-02-23
Abstract: PURPOSE:To simplify circuit constitution by using a switching element for chopper and a switching element for inverter in common, and arranging such that the current flowing to the inductance for energy accumulation of a chopper does not become zero while this shared switching element is off. CONSTITUTION:To continue current flow through a load 2, it is necessity to turn on a transistor Q1 for some period or sustaining the current IL1 of an inductance L1 above 0 at all times. If the transistor Q1 is kept off at all times, it is necessity to put the current to IL1>0. If the circuit constant is designed to meet this condition, high frequency voltage is supplied to a load circuit 2 only by the on-off operation of a transistor Q2 even if the transistor Q1 is not turned on. Accordingly, the transistor Q1 can be omitted.

Filed: 1990-02-26
Abstract: PURPOSE:To decide rewinding operation time by counting the number of pulses based on pulse width measured by a pulse width measuring circuit with a pulse number counting circuit. CONSTITUTION:In a reproducing operation, a pulse signal outputted from a pulse signal generation circuit 21 is inputted to the pulse width measuring circuit 20, and the pulse width of the signal is measured by the pulse width measuring circuit 20. At this time, when a switch 10 for stoppage is depressed and closed, the output signal of an output terminal 13 for reproduction is inverted from an H level to an L level, and also, the output signal of an output terminal 17 for rewinding is inverted from the L level to the H level. Consequently, a tape recorder, after it is released from the reproducing operation, is set at a rewinding state, then, the rewinding operation of a magnetic tape is started. When the rewinding operation of the magnetic tape is started, the number of pulse signals outputted from the pulse signal generation circuit 21 is counted by the pulse signal number counting circuit 22. Thereby, the rewinding operation time can be decided.
