Patent JP-H06261537-A (JP)
Title: Power unit
Inventor: MORO MASARU
IPC: H02M3/07
Filed: 1993-03-10
Abstract: PURPOSE:To reduce the impedance of a capacitor without increasing the capacitance of the capacitor so as to increase the load current of a power unit which lowers the output voltage of commercial power supply by using the capacitor and making an electric current having a frequency higher than that of the commercial power supply to flow to the capacitor by providing an oscillator. CONSTITUTION:An oscillator 4 controls a transistor 2 by outputting a signal having a frequency higher than that of commercial power supply 102. When the transistor 2 is repeatedly turned on and off, a voltage which is obtained by dividing the voltage of the commercial power supply 102 rectified by means of a rectifier circuit 103 by the impedance of the capacitor 1 and resistance of a resistor 3 is generated across the section B. At the same time, the impedance of the capacitor 1 changes depending upon the oscillation frequency of the oscillator 4 and the voltage across the section B also changed. The voltage across the section B is supplied to a load 107 through a constant-voltage circuit 106 after smoothing the voltage by means of the capacitor 106. Therefore, the capacitor 1 allows a large load current to flow even when the capacitor has a small size.

IPC: B65G67/60
Filed: 1984-03-15
Abstract: PURPOSE:To enhance the degree of accuracy for measuring a dewatering amount which is actually measured, by periodically obtaining a compensating coefficient between a value actually measured by a weighing device in an unloader on operation, and a proportional value measured by a weighing device in a transfer conveyor line, so that the actually measured value by the weighing device in the unloader is compensated with the use of the thus obtained compensating coefficient.

The computer 5 computes proportional values WU1 for the respective unloaders in accordance with the weighed values from the unloaders and the transfer belt conveyor line, and stores the thus obtained proportional values and the weighed values U1 from the unloades are stored in a memory. When the values in the number of (m) have been stored in the memory, compensating coefficients (a, b) for the respective unloaders are calculated with the use of a regression line equation. With the use of these compensating coefficients (a, b) values actually measured by the weighing devices in the unloaders are compensated so that the dewatering of the raw material may be made with a high degree of accuracy.
