Title: Optical magnetic recording reproducer
Inventor: MATSUMURA SUSUMU
IPC: G11B11/105
Filed: 1990-11-22
Abstract: PURPOSE:To enable high-density recording by detecting the direction of magnetization of an information magnetic domain recorded on an information track and changing over and controlling the direction of the magnetic field of a magnetic-field applying means on the basis of a detection result. CONSTITUTION:The upper section of an information track is irradiated with a light spot using the light intensity of a semiconductor laser 7 as recording power. A bias magnetic field modulated in response to recording information is applied simultaneously from a magnetic head 1, and an information magnetic domain is formed onto the information track. The light intensity of the semiconductor laser 7 is lowered to reproduction power in the reproduction of information, and the light spot of luminous flux for reproduction is scanned on the information track. On the other hand, the magnetic head 1 generates a magnetic field H weaker than that at the time of recording, and the magnetic field H is applied to the information track. The magnetic field for reproduction is controlled so as to be directed in the same direction as the direction of magnetization of the information magnetic domain, moves the domain wall of the information magnetic domain and functions to increase the magnitude of the magnetic domain. Accordingly, a reproduction density limit can be relaxed, thus further augmenting the recording density of a recording medium.

Title: Zero-phase-current measuring circuit of three-phase alternating current
Inventor: KOJIMA TOSHIAKI
IPC: H01F38/28
Filed: 1994-11-28
Abstract: PURPOSE: To obtain a zero-phase-current measuring circuit which suppresses the generation of a residual current and which can perform a measurement with a small error by arranging conductor axial lines for a three-phase AC circuit to be an equilateral triangle and installing a photosensor in their center. CONSTITUTION: Three conductors are arranged in such a way that they are mutually parallel and that their respective axial lines form an equilateral triangle, and a photosensor is installed in their center. When the photosensor is installed, it is directed to a direction which forms 90 deg. with magnetic fluxes generated by conductor currents, and a central line which connects a source to a drain becomes parallel to the conductors. When the photosensor is installed in the center of the equilateral triangle, a magnetic field in the central point of the conductors becomes H=(Ia +Ib +Ic )/(2πr) when distances are r=ra =rb =rc , and the magnetic field which is proportional to a zero-phase current can be obtained.  The magnetic field is received by the photosensor, it is converted into an electric signal by a photoelectric converter, and the zero-phase current is computed on the basis of the magnetic field and the distance. Thereby, currents Ia to Ic are magnetically coupled to the central point without using a magnetic substance such as an iron core or the like, and the photosensor is a nonmagnetic substance. As a result, a residual current is suppressed without disturbing the magnetic field, and a measurement whose error is small can be performed.

Title: Semiconductor device
Inventor: TAKEUCHI MIKI
IPC: H01L29/786
Filed: 1994-12-21
Abstract: PURPOSE: To obtain a semiconductor device in which the gate capacitance of a switching element is reduced, which is operated at a low voltage, whose speed and reliability are high and whose power consumption is low by a method wherein resistance between a source and a drain is controlled by a voltage applied to the gate. CONSTITUTION: Heavily doped p-type Si regions DK1, SK1 are formed inside a WEL 1, and resistance between the DK1 and the SK1 is modulated by gates G1a, G1b. For example, when a positive voltage is applied between the gates G1a, G1b, a depletion layer is extended so as to be set to a state that a switch has been turned off. When the voltage between the gates G1a, G1b is changed to the negative direction, a neutral p-type region is formed between a part D1a and a part D1b so as to be set to a state that the switch has been turned on. Thereby, an operation in which an Si surface under the gates is inverted so as to store carries is not required, and the capacitance of a semiconductor device can be reduced while a current which is equal to that of a MOS transistor is being ensured.
