Title: Magnetic disk recording and reproducing device
Inventor: SATO MASAKATSU
IPC: G11B21/02
Filed: 1990-03-26
Abstract: PURPOSE:To always make torque to be generated by a stepping motor constant by providing a circuit for converting a voltage supplied to a magnetic recording and reproducing device into a rating voltage for driving the stepping motor. CONSTITUTION:A DC voltage +E1 from a power source circuit 3 is directly impressed on the magnetic recording and reproducing circuit 1, and is also impressed on a voltage conversion circuit 10. A comparison is made between the voltage +E1, and a prescribed voltage +E2 by the circuit 10, and normally the voltage +E1 > the voltage +E2 so that the voltage +E1 is converted into the constant voltage +E2, and when the voltage is drastically dropped to equal the voltage +E2 or less than that, the voltage conversion is not carried out, and this voltage is directly impressed on a stepping motor driving circuit 2. By this constitution, the rating voltage that is always constant can be supplied to the stepping motor 4 that is most susceptible to voltage fluctuations, and hence even when the voltage to be supplied to the magnetic recording and reproducing circuit 1 is varied, the torque to be generated by the stepping motor 4 can be made to be constant.

Title: Current detector
Inventor: MATSUSHITA AKIRA
IPC: G01R19/165
Filed: 1987-03-31
Abstract: PURPOSE:To obtain a small-sized inexpensive current detector having extremely high accuracy, by generating a pulse signal in the detection coil of a magnetism- sensitive element at the point of time when the next positive magnetic field acts when the negative magnetic field due to a current to the detected is larger than a bias magnetic field. CONSTITUTION:At first, a constant bias magnetic field HDC is always allowed to act on a magnetism-sensitive element 1. Herein, when the external magnetic field HAC generated by the AC current I to be detected flowing to an exciting coil 3 is smaller than the absolute value of the max. peak value thereof, any special phenomenon is not generated in the element 1. However, when the magnetic field HAC larger than HDC acts, at first, a negative magnetic field HR acts on the element 1 and a part low in coercive force is transformed in a negative direction and again reversed in a positive direction by a positive magnetic field HS acting in succession. This transformation speed is especially rapid. Therefore, since a steep pulse signal VS is induced in a detection coil 2 at the point of time when a limit magnetic field HL necessary for generating transformation acts, by detecting the signal VS, it is discriminated that the prescribed current to be detected is supplied.
