| 摘要 | PURPOSE: To simplify the constitution of a device and to miniaturize the device by detecting a Coriolis force acting to the flow of electrons inside a semiconductor when the angular velocity is impressed to the semiconductor with the use of a voltage detecting means. CONSTITUTION: A current impressing means 23 is connected between a first and a second electrodes 21 and 22 of a semiconductor 20 formed of a Hall device so as to impress a predetermined current I. A voltage detecting means 26 for detecting the voltage is provided between a third and a fourth electrodes 24 and 25 of the semiconductor 20 via a lead wire 27. When a uniform current, I x is impressed between the electrodes 21 and 22, the flow of electrons A and the line of the equal potential B are such as indicated by a solid line and a chain line, respectively. The Hall effect when an eternal magnetism B z is applied is F=Qψ×B z (wherein ψ is the velocity of electrons and Q is the electric charge). When the Coriolis force acts to the flow of the electrons as a result of the application of the angular velocity, the Hall effect, becomes F=-2mψ×ω (wherein ω is the angular velocity and (m) is the mass of electrons). Accordingly, a voltage can be generated when the angular velocity is added. COPYRIGHT: (C)1992,JPO&Japio |
