Title: Control system for magnetic flux control type pwm inverter
Inventor: YANASE TAKAO
IPC: H02M7/48
Filed: 1985-11-27
Abstract: PURPOSE:To eliminate a special circuit for generating a weakening magnetic flux pattern by providing the amplitude of a magnetic flux command value with a constant value over the entire frequency range irrespective of the bases frequency to inverter-control it. CONSTITUTION:A frequency command from a frequency command setter 1 is applied to a V/F converter 2 which converts it into a pulse signal proportional to the frequency. A counter 3 reads out a unit sinusoidal signal from a sinusoidal ROM 4 by counting the pulse signal. A D/A converter 5 is composed of a type that the peak value of a sinusoidal signal is, for example, applied externally as an analog amount and therefore can obtain a magnetic flux command value of an analog amount of a predetermined amplitude with a constant value externally applied to it.

Title: Positive characteristic thermistor element
Inventor: ODA MASARU
IPC: H01C7/02
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To limit current to protect against overvoltage in a short period of time using this thermistor element as an overcurrent limiting element by a method wherein a layer, composed of at least three layers in the direction vertical to an electrodes surface and having a high specific resistance, is provided almost in the center part of a ceramic element as an overcurrent restricting element. SOLUTION: A specific resistance (Q.cm) of the ceramic element 3 of the center part is higher than the specific resistance of the ceramic elements 2 and 4 of the surface layer. On this positive characteristic thermistor(PCT) element, an electric field is concentrated on the high resistance layer of the PCT element center part when very large overvoltage such as 600V is applied. As a result, the center part of the PCT element is laminarly cracked with certainly by the difference of temperature generated between the surface layer and the inner layer of the PCT element. On the other hand, when 200V or thereabout is applied, current can be controlled in a short period of time to limit overcurrent.
