Title: Semiconductor memory device
Inventor: SUZUKI TAKASHI
IPC: G11C11/34
Filed: 1985-01-28
Abstract: PURPOSE:To initialize a storage device to an optional pattern at a power-on time by the storage device itself, by initializing initial data of a memory cell through a switch means which is controlled to the turn-off state during the normal operation. CONSTITUTION:When a power source is turned on and a supply voltage VCC rises, an N-type depletion transistor Tr3 of the switching means is turned on until a substrate bias voltage VSUB rises up to the threshold voltage of the Tr3. Therefore, a node B of the memory cell of an FF formed with TRs Tr1 and Tr2 reaches the voltage VCC more quickly than a node A. Consequently, the storage device is initialized to an optional pattern at a power-on time by the storage device itself without a CPU or the like if the TRTr3 is connected to either node side.

Title: Driving device for discoid information recording medium
Inventor: FUJIOKA SOICHIRO
IPC: G11B19/20
Filed: 1988-01-25
Abstract: PURPOSE:To easily realize the compact structure of the title driving device as well as the reduction of power consumption by producing a Foucault current (eddy current) via a discoid information recording medium where a superconductive material is vapor-deposited and revolving said recording medium. CONSTITUTION:The current flowing to a coil 3 connected to an AC source 4 produces an AC magnetic field to produce an eddy current on a superconducting material vapor- deposited on an optical disk 1. Then Lorentz force is produced by the function of said eddy current and AC magnetic field and torque is produced for the disk 1 set around a support mechanism 2. Thus the disk 1 is rotated. The electrical resistance is equal to zero and a large eddy current is produced with a small loss and the satisfactorily large torque in a super conductive state since a superconducting material is used as a generator of eddy current. Thus the energizing current of the coil 3 can be reduced and therefore the reduced power consumption is facilitated. Furthermore, it is not required to set the coil 3 at the center of the mechanism 2 and the coil 3 can be set at an optional position. As a result, the structural limitation is minimized and a compact driving device is easily obtained for a discoid information recording medium.
