Title: Automatic control method for torque boost of inverter
Inventor: YAMADA TETSUO
IPC: H02P21/00
Filed: 1989-03-13
Abstract: PURPOSE:To perform a constant magnetic flux by detecting an induction motor current and a power factor angle, calculating a terminal voltage with an exciting voltage set value and a motor primary resistance set value, and controlling an inverter with the calculated voltage as a voltage command signal. CONSTITUTION:An induction motor current I1 and a power factor angle theta are detected, and a terminal voltage V1 is calculated by a formula I or II with the current I1 signal, an exciting voltage E set value proportional to the angle thetaand a set frequency and a motor primary resistance R1 set value. An inverter is controlled with the calculated voltage V1 as a voltage command signal. The inverter outputs the voltage V1 as a frequency (f) and the V1 command from a calculator I1. Thus, the exciting voltage E of a motor 6 becomes proportional to the frequency, and a magnetic flux becomes constant.

Title: Multilayer printed wiring board
Inventor: MATSUBARA TAKAO
IPC: H05K3/46
Filed: 1989-03-13
Abstract: PURPOSE:To prevent the price from increasing and a region where wiring of conductor patterns is restricted from being produced by bending and adhering one flexible substrate. CONSTITUTION:Conductors 3, part pads 2, through holes 4, and exposed interlayer connection conductors 5 not covered for insulation are formed on a bendable double-faced flexible substrate 1. Said substrate 1 is bent at appropriate parts to connect the conductors 5 vertically opposite by using conductive adhesive 7 or solder. Vertically opposite insulating films 6 are adhering by applying insulating adhesive 8 thereto to form a multilayer structure. Therefore, a multilayer substrate can be made only by patterning one double-faced substrate. The through holes in the internal layers do not bore the multilayer substrate from the top layer to the bottom layer. Thereby the price decreases and wiring of conductor patterns is not restricted.
