Title: Arc welding device
Inventor: YASUHARA YOSHIMICHI
IPC: B23K9/073
Filed: 1979-01-24
Abstract: PURPOSE: To regulate output voltage with ease with a simple three-phase transformer by providing taps to be provided to the primary side wirings of the three- phase transformer to one phase alone, using only the two phases for the secondary side winding and making V-connection.  
     CONSTITUTION: Taps are provided to one phase of primary side windings 1 and the end part of the primary side windings is connected to the primary side windings of the other two phases. The secondary side is wound with two phases along. The line voltages VUV, VVW, VWU among the primary side windings are applied with balanced three-phase voltage. Depending upon the connection positions of the taps, it is possible to change the magnitude of the voltage VOU across the primary side windings. The magnitudes of the voltages VOV, VOW across the primary side windings of two phases may be changed as desired. The magnitudes of the voltages VUV, VWU across the secondary side windings become those comprising multiplying the primary side voltages of VOV, VOW by turn ratio. Hence, the secondary side output voltage waveform has the same waveforms with the secondary side voltages VUV, VWU, thus it changes with the taps but VVW becomes always constant.

Filed: 1995-01-20
Abstract: PURPOSE: To automatically count the number of beats per unit time, BPM value, by a method wherein a clocking operation is started at a point of time when the level of a predetermined frequency component for an input audio signal exceeds a predetermined value, a circuit is changed over and the clocking time up to a point of time when the level exceeds the predetermined value again is used as a unit beat. CONSTITUTION: An audio signal is passed through an A/D converter 1, and a low-frequency component is extracted by a BPF 2 for a BPM detection part 101 so as to be supplied to a changeover switch 11. A peak-value holding circuit 3 and a threshold- value generation circuit 4 are connected to one contact, a threshold is value is generated, and a signal-slice-pulse converter 5 is connected to the other contact. The converter 5 outputs a high level when a supplied signal level exceeds the threshold value, and a window timer 6 changes over the switch 11 to the side of the converter 5 from the side of the circuit 3 after a prescribed time clocking operation has been finished. A BPM converter 7 converts a BPM value on the basis of the counted time in which the converter 5 has output the high level so as to become the high level again.  BPM detection parts 102, 103 perform an operation in the same manner, and they extract an intermediate-frequency region and a high-frequency region by means of the BPM 2.
