Title: Ultralow variable speed driving system
Inventor: ISHIZAKI AKIRA
IPC: H02P27/06
Filed: 1985-07-29
Abstract: PURPOSE:To prevent a current flow generated resultantly from a low speed rotation from increasing by reducing the resistance of an induction motor and increasing a leakage reactance from a normal design to suppress a current value. CONSTITUTION:A squirrel-cage induction motor generates a very large synchronous torque with a slip of S=1-P/Z2 when Z2=Z1+P is satisfied among rotor slot number Z2, stator slot number Z1 and pole number P. When an ultralow speed operation is executed by utilizing the harmonic wave synchronous torque, a large current can be suppressed by setting the motor to a low resistance and high leakage reactance.

Title: Semiconductor device and hybrid integrated circuit device with it built in
Inventor: OHAMA TAIZO
IPC: H01L25/18
Filed: 1995-06-30
Abstract: PURPOSE: To miniaturize a semiconductor device and a hybrid integrated circuit device for use in power controlling equipment and apparatus, and stabilize their thermal characteristics. CONSTITUTION: An NPN power transistor Q1 and an NPN power transistor Q2 are adjacently formed to obtain a chip. At this time they are rotated relative to each other so that the positions of their emitters and bases will be reversed. When the composite NPN power transistor chip 11 is supplied with power and actuated, it generates heat. The figures (b), (c) and (d) show the distribution of heat. Since the NPN power transistors Q1 and Q2 are adjacently formed at a rotational angle of 180 deg. to each other, heat is uniformly distributed in the central portion of the composite NPN power transistor chip, which then operates without the concentration of heat on one side. This ensures the stable operation of the composite NPN power transistor chip 11, and makes it possible to form a semiconductor device resistant to heat concentration arising from composition.  Combining NPN transistors Q1 and Q2 into one chip to obtain a semiconductor device makes it possible to reduce heat sinks and thus the mounting area of a hybrid integrated circuit device.

Abstract: PURPOSE:To improve the performance of both of the undermentioned two elements by compatibility with each other by a method wherein the impurity concentration of the region for forming an active element for small signal formed together with an active element of high withstand voltage is selectively reduced with an impurity of reverse conductivity type. CONSTITUTION:The regions a1-a3 having grooves by anisotropic etching are selectively provided with n<-> layers 16, and an n-layer 20 is superposed and covered with an SiO2 mask M. An n type and a p type impurity are successively implanted 18 to the regions a2 and a3 and then heattreated, resulting in a decrease in the n-concentration of the surface of the layer 20; thereby enabling the formation of a Schottky barrier diode made of metal silicide, and thus keeping the depth conductivity better. The regions are separated from each other by means of p<+> layer, n<+> layers 15 being led out through p<+> layers 24, and a p layer 30 and an n<+> layer 32 being then provided as required. Thus, the n type impurity concentration of the epitaxial layer 20 is kept low in the region a1 and selectively high in an n-p-n element Q1 and the other region by the settlement of a recess groove; accordingly the parasitic resistance is reduced and the hFE is increased. The n-p-n elements Q2 and Q3 with built-in Schottky diodes 40 can be formed in the region a2 by series providing with n<+> layers 23, a lateral n-p-n element Q4 in the region a3, and complementary elements Q5 and Q6 in the region a4 by coexistence.
