Title: Generator controlling method
Inventor: UCHINO HIROSHI
IPC: H02P9/00
Filed: 1989-06-01
Abstract: PURPOSE:To perform PWM control by turning OFF switching elements constituting a comparator for a predetermined period, whenever an output current value reaches a predetermined level in the process where said value increases. CONSTITUTION:U-phase current 1, V-phase current 2 and W-phase current 3 increase by the increase of the positive side command value 4 and negative side command value 5 of output current width command values 5. In this manner, the output voltage 14 of a converter 3 approaches an output voltage command value 11. After the voltage has risen to the command value, a load is closed to perform a voltage control. In this case, if a breaker 13 is turned ON, the load 14 is supplied with power 15. At this time, the output voltage 14 of the converter 3 is lower than the voltage command value 11, but the voltage command signal 16 corresponding to the deviation is generated when a voltage control circuit 12 is turned ON. Thus, U-phase, V-phase and W-phase currents 1, 2, 3 can be controlled by the control of the positive side command value 4 and negative side command value 5 of said output current amplitude command values 5.

Title: Manufacture of foam insulating wire
Inventor: SHIBATA NOBUYUKI
IPC: H01B13/14
Filed: 1989-05-31
Abstract: PURPOSE:To stabilize resin foaming by setting an inner diameter of a pipeline through which foaming gas is injected from a pump to an extruder cylinder in such a manner that a volume of vaporized gas in the pipeline is smaller than that of gas per minute injected into the cylinder. CONSTITUTION:A pipeline C introduced from a pump B to an extruder cylinder A has a small diameter. A volume of the portion 1 of the pipeline C where fleon gas is vaporized is smaller than that of gas per minute injected into the cylinder A. Accordingly, the vaporized fleon gas in the pipeline C is decreased so that a change in the injected gas along with a pressure fluctuation in the extruder cylinder A becomes small. Therefore, the gas can be stably supplied in the cylinder A, and then, foaming of an insulator (b) in the cylinder A becomes stable. Consequently, a foaming insulative wire (d) of high quality can be obtained with a little variation in foaming state or thickness of the insulative layer (b).
