    • A pulse signal shaper supplying a pulse signal having a stable pulse width, including an input circuit that produces a first pulse signal in response to an input signal, a delay circuit that produces a second pulse signal obtained by delaying the first pulse signal by a predetermined time, and a signal mixing circuit that is connected to the input circuit and the delay circuit. The mixing circuit combines the first pulse signal and the second pulse signal to produce a third pulse signal having a pulse width equal to or greater than a delay time provided by the delay circuit, and supplies the third pulse signal as an output signal from the pulse signal shaper. In a preferred embodiment, the input circuit includes an oscillator responsive to the input signal. When the input signal has a higher frequency than a predetermined frequency, the input signal is supplied as the first pulse signal at a frequency equal to te frequency of the input signal. When the input signal has a lower frequency than the predetermined frequency, the first pulse signal is supplied at the predetermined frequency.

    • A format operation control device performs a simple format operation and a standard format operation for a recording medium having a control data area, storing file control information, and a record data area, storing record data. The control data area and the record data area have sectors. In the simple format operation, the control data area is initialized and bad sectors are not detected from each of the sectors of the recording medium. The standard format operation includes a substitution process and a bad sector mapping. In the substitution process, the control data area is initialized, bad sectors are detected from each of the sectors of the recording medium, and a physical format is performed so that good sectors are used instead of bad sectors. In a bad sector mapping, the control data area is initialized, bad sectors are detected from the record data area, and a bad mark is recorded in the FAT-table corresponding to the cluster containing the bad sector.

    • A circuit and method for controlling an output current balance for parallel driven PWM-type digitalized power inverting units are disclosed in which a feedback control such that rising edge times and falling edge times of a PWM waveformed pulse train signal to be supplied to the parallel driven power inverting units are respectively corrected using independent correction signals is carried out to eliminate a deviation between output currents of the parallel driven power inverting units. The correction of the rising edge times and falling edge times is such that a phase advance correction for the one unit with respect to an offset value delay and a phase retardation correction for the other unit with respect to the offset value delay are carried out so that a delay of an average output current with respect to the PWM waveformed pulse train signal is made constant. In addition, if an integration calculation of the feedback control is carried out during a constant period of time upon a change in the PWM waveformed pulse train signal to suppress an abnormal integration. Ripple components due to a generation of output current unbalance can be suppressed by limiting the corrections to the falling edges and rising edges of the PWM pulse train signal to either one according to a polarity of the deviation between the output currents of the power inverting units.

    • In a vehicle assembling line in which parts are assembled to a vehicle body while the body is passed through each of working stations by a plurality of transporting means, the vehicle body is positioned and supported by a pallet and transported by each of the transporting means, wherein transferring of the body between the transporting means is carried out through the pallet. A transporting path, on which a self-travel carriage as the transporting means travels, is laid within a pit concavely provided below a floor plate of a working floor. Arranged above the floor plate are a carriage frame, a lift table and a turn rest for supporting the pallet, which constitute an upper portion of the self-travel carriage. The transporting path is disposed substantially along the assembling line from its starting point to its terminal point, and an automated assembling zone and a manually assembling zone are coexistently disposed along the assembling line. An automatic machine is disposed in a working station of the automated assembling zone for advancing and retreating movement, and there is provided means for positioning and fixing the self-travel carriage together with the pallet in such working station. An overhead conveyor for transporting the self-travel carriage separated from the pallet in a hung manner is used as one of the transporting means.
