Filed: 1986-01-17
Abstract: PURPOSE:To attain stop state without oscillation by providing a correcting circuit so that a force which has the same magnitude as the force, which a motor shaft receives because of gravity, and has a direction opposite to that of this force is generated in a motor steadily. CONSTITUTION:VW' (t)=VW(t)+VR is true where VW is the input voltage inputted to a conventional power amplifier and VR is the voltage outputted from the correcting circuit and VW' is the input voltage inputted to a power amplifier 5 to which the voltage VR is applied.

Abstract: PURPOSE:To restrain the concentration of an electric field at the boundary end part of a diffused region formed by the system of self-alignment and thus enable the large stabilization of characteristics by ion-implanting the first impurity to a selective region of a semiconductor substrate, and the second impurity via a coated film of the oxy derivative of silicon. CONSTITUTION:An N type diffused region 17 is formed by the diffusion of an arsenic implanted region 14 and a phosphorus implanted region 16, and becomes a region of different impurity concentrations consisting of an arsenic diffused region 17a and a phosphorus diffused region 17b, in the neighborhood of the end part of a polycrystalline Si layer 13 serving as a gate electrode. Since the diffusion constant of arsenic is smaller than that of phosphorus, the arsenic diffused region 17a has small expansion also to immediately under the gate electrode, and has a low concentration. On the other hand, the phosphorus diffused region 17 17b is deep and has large expansion, but has the distribution of the amount of implantation depended on the thickness of a silanol film 15, because the phosphorus ion implanted region 16 via the silanol film 15 is the diffusion source, thereby the expansion to the location immediately under the gate electrode hardly occurs.

Filed: 1995-01-24
Abstract: PURPOSE: To avoid such a fact that respective secret codes of two keys become uncontrollable because of interfering with each other by installing a shield means shielding a transponder as being free of releasing. CONSTITUTION: A transponder part is housed in each plastic handle part 4 of both immobilizers 1 and 2, or two pieces of keys, and a taper 6 consisting of copper or the like is stuck on a surface of this handle part 4 free of detachment. Each key part 3 of these two immobilizer keys 1 and 2 is formed into the same form, but each of the transponder parts 5 is constituted so as to form different secret codes. In a state that the tape 6 is stuck to the handle part 4, since any magnetism to be fed to this transponder part 5 owing to magnetic coupling from an immobilizer control part is interrupted by this tape 6, there is no case that this transponder part 5 will radioingly output any secret code by means of the magnetic coupling. In addition, in another state that the tape 6 is removed away, power is fed to the transponder part 5 from the immobilizer control part by means of this magnetic coupling, and thus the secret code is radioingly outputted by means of the magnetic coupling.
