Title: Semiconductor device
Inventor: TOMITA YUTAKA
IPC: H01L21/22
Filed: 1978-09-14
Abstract: PURPOSE: To prevent contact between the isolated and buried areas by using the actual buried area and the shifted area, when growing an epitaxial layer on the semiconductor base having a buried area and here forming the isolated area by diffusion.  
     CONSTITUTION: To diffuse and form an N + -type buried area 2 on a P-type semiconductor base for the purpose of lowering the collector linear resistance, to remove the thereby produced SiO 2  film 3, and to grow epitaxially an N-type layer 4 on the whole surface. By doing so, simultaneously an SiO 2  film 5 will be produced on the surface. Because of the condition of epitaxial growth, however, the said film does not correspond to the buried area but a shifted hollow trace 6 will be produced. Consequently if P + -type isolated area 7 will be formed by diffusion, using the pattern shifted intentionally from this trace, the area 7 may contact or too much near the area 2. As mask pattern to prevent this, a mask consisting of the shaded portion 14 corresponding to the actual area 2 and the solid line portion 12 visible from the top of the layer 2 will be prepared to locate, using the shaded portion 14.

Title: Current control device in speed control device of dc motor
Inventor: YOSHIDA NORIYUKI
IPC: H02H7/08
Filed: 1981-07-21
Abstract: PURPOSE:To evenly control the excessive current of the DC motor and a power source by a method wherein power is supplied without interruption for the instantaneous overload arising on the DC motor, whereas power supply is shut off for an excessive overload. CONSTITUTION:A comparator 9 gives a control signal to the transistor 6 to be used for power by comparing the saw-toothed wave voltage, which is in proportion to a speed setting value, with a speed voltage VS. When the load is instantaneously increased and the speed of the motor is reduced, the ON state of the transistor 6 for power continues, and the driving current applied to the motor 3 from capacitors 4 and 33 increases. When the motor 3 runs into a locked state due to an excessive load, the detection voltage of a detecting resistor 5 reaches the limit value, the transistor 24 is turned to ON position, and the power transistor 6 is turned to OFF position. This state is maintained until the total value of the emitted current of the energy accumulated in the motor 3 and the charging current of the capacitor 33 reaches the limit value or below.

Abstract: PURPOSE:To reduce the cost of production in addition to the promotion of lightweightness as well as to simplify an assembling property by forming a clutch shoe, where such a formed hinge as being thinly constricted in the root part is formed, into an integral forming member by means of resin. CONSTITUTION:A clutch shoe 1 is integrally formed by fiber reinforced plastics, embedding two metal pieces 11 inside, and a hinge part 1a of this clutch shoe 1 stiffens the fiber orientation of resin in the circumferential direction, thereby improving the strength.
