Title: Electric vehicle
Inventor: TAKECHI HIROAKI
IPC: H02P27/06
Filed: 1986-06-27
Abstract: PURPOSE:To momentarily control the torque of an electric motor vehicle by forming a primary current command controlled in frequency and amplitude on the basis of an output of an acceleration command unit. CONSTITUTION:When an accelerator pedal is depressed, the output voltage of a potentiometer 21 rises. This signal is input as a slip frequency omegas to an adder 70 to be added to the output omegar of an F/V converter 69, and the adder outputs a synchronous rotation frequency omega1. The frequency omega1 is converted to quantized sinusoidal waves of four types having a frequency corresponding to the value of the frequency omega1 through a counter 23 and a ROM 24. The waves are converted to analog 3-phase primary current commands controlled in amplitude through a D/A converter 25, adders 27 and 28, and a 2-phase/3- phase converter 29 on the basis of a secondary current command signal iz and exciting current signal i0.

Title: Field effect semiconductor device
Inventor: YANAGAWA SHIGERU
IPC: H01L29/80
Filed: 1981-09-25
Abstract: PURPOSE:To lower the temperature of operation layer without deterioration of electrical performance by arranging the striped channel regions around the region in higher resistance than that of channel region and causing the crossing finger-shaped source drain electrodes and the gate electrodes formed between them to cross the striped region. CONSTITUTION:When the belt-shaped region in higher resistance than the region 14 (any type of p. n. i is allowed ) 15 is formed in the longitudinal direction X at the center of the active region 14 on the semi-insulating substrate 16, heat radiation within this region is reduced. Since (the corresponding gate width)= lX (number of the gates) is necessary for obtaining the required output of FET, the number of lines of gate electrodes 13 are determined by selecting the width l of the active region 14 and the width l' <0.25l of the high resistance region 15 and the carrier concentration of region 15 is kept equal to that of the substrate 15 and thereby a drain current flowing into the region 15 is set to zero. Accordingly, the maximum temperature of finger electrode is generated at the point F of (l-l')/4 and temperature rise is reduced because of existence of the region 15. For this reason, the average fault period by migration of gate metal is elongated by about 50%.

Abstract: PURPOSE: To effectively detect an error without increasing effective data bandwidth while reducing noise due to simultaneous switching by coding data signals to be outputted from the output pins of a digital IC chip so that they have equal numbers of 1's and 0's in respective cycles. CONSTITUTION: This coding constitution is outputted so as to code the output pins of a single end of the digital IC chip, respective coded words have equal numbers of 1's and 0's, and equal numbers of driving currents and sink currents are therefore generated, so that a net signal current of 0 is left.
