Patent JP-H0855483-A (JP)
Title: Semiconductor device
Inventor: KATO KEI
IPC: G11C11/409
Filed: 1994-08-15
Abstract: PURPOSE:To maintain low power consumption of a device and to increase operation speed by controlling a driving current in each mode of a normal operation state, a standby state and a stop state of a differential circuit. CONSTITUTION:In a normal operation mode of a memory with a logical function and in a selecting state in a read-mode of a corresponding memory module, a driving current value supplied to differential circuits DC1, 2 through an internal node n1 is made large by large conductance of MOSFET NE, NF. Also, in a normal operation mode and in a non-selection state of a corresponding memory module or in a write-mode and in a selection mode, conductance of FETNC is restricted, and a supplied driving current value of the circuits DC1, 2 is made small. When a memory with a logical function is made a standby mode, an internal control signal RMO and a standby signal STB both are made a low level, a driving path of a sense amplifier consisting of the circuits DC1, 2 is cut off and a current is not made to flow. Thereby, low power consumption of the memory module and the memory are maintained and operation speed is increased.

Title: Magnetic disk device
Inventor: UCHIKURA HIDEAKI
IPC: G11B33/14
Filed: 1982-12-07
Abstract: PURPOSE:To have an equal air current and then an equal rise of temperature for each face of a magnetic recording medium and to reduce the track positioning error due to the difference of heat expansion, by setting a disk having the same size as the recording medium at both ends or one end of an aggregate structure of the magnetic recording medium. CONSTITUTION:The temperatures rise up by the air friction, etc. at spaces 15- 18 among recording media 11-14 after the revolutions of these media are started. Thus the media 11-14 and magnetic head arms 23 and 24 are expanded. If disks 19 and 20 are not available, the temperatures of spaces 15 and 18 are different from those of spaces 16 and 17. Therefore the expansion degree between the media 11/14 and the arm 23 is different from that between the media 12/13 and the arm 24. With existence of disks 19 and 20, the rise of temperatures at spaces 15 and 18 is equal to that at spaces 16 and 17. Thus the expansion degree is equal between media as well as between head arms. This improves the track positioning accuracy.
