Abstract: PURPOSE:To enhance protection effect and eliminate the need for increasing resistance of a protective resistor by combining a protective diode especially although a protective resistance is inserted between an output terminal and a FET normally and by absorbing excessive voltage through breakdown and conduction on intrusion of high voltage. CONSTITUTION:An N<+> type embedded layer 2 is diffused at the center of a surface layer part of a P-type Si substrate 1, it is included and an N-type epitaxial layer 3 is allowed to grow while isolating by a P<+> type layer 4 on the periphery, and a generated N-type region 5 is subjected to junction-isolation from the substrate 1. Then, a protective resistor R consists of N-type pair of resistance connection layers 6 with high impurities concentration by diffusion from the surface of the region 5. At this time, two of half Rs which face in vertical direction within the region 5 are used, which are connected in series. Then, a protective diode D which is combined with the resistor R consists of the region 5, the substrate 1, and the layer 4, breakdown voltage when a voltage in opposite direction is applied is set to only several 10V, thus resulting in breakdown when an electrostatic high voltage exceeding several hundreds of volts is applied.

Abstract: PROBLEM TO BE SOLVED: To form a compact profile, by disposing a first reduction gear mechanism and second reduction gear mechanism in a case, and largely decelerating rotation of an armature shaft by them to be given to an output member. SOLUTION: A worm gear 12a is constituted at a protruding side of an armature shaft 13 in a gear case 3. The worm gear 12a is engaged with a wheel gear 19 to constitute a first reduction gear mechanism 9. An inner gear 21 is disposed at an upper side of the gear 19. The gear 21 is engaged with an outer gear 22 disposed at its outside, and a second reduction gear mechanism 20 is constituted by the gear 22 and an output wheel 23 disposed at an upper side of the gear 21. Thus, since rotation of an armature shaft 12 is largely decelerated by the mechanism 9 and a second reduction gear mechanism 10 to be given to an output member 11, a complicated gear is not required to decelerate the rotation of the shaft 12, and the member 11 is not largely projected on the mechanism 10.
