Title: Digital line sense circuit
Inventor: OYAMA JUNICHIRO
IPC: G11C11/406
Filed: 1990-04-27
Abstract: PURPOSE:To reduce the chip area and the current consumption by performing the self-refresh operation by a sense amplifier for self-refresh. CONSTITUTION:The self-refresh operation is performed by a sense amplifier 36 for self-refresh. That is, the sense amplifier 36 for self-refresh is in the waiting state when a normal sense amplifier 37 performs the refresh operation based on the lower address, and the normal sense amplifier 37 is in the waiting state when the sense amplifier 36 for self-refresh performs the refresh operation. Consequently, the increase of the chip area is reduced as much as possible and the current consumption is reduced to a half only at the time of self-refresh because the number of operated blocks is apparently increased twice in the self-refresh mode. Thus, the chip area and the current consumption are reduced.

IPC: G11B5/735
Filed: 1989-05-02
Abstract: PURPOSE:To obtain a magnetic tape free from head clogging and has excellent quality for recording/reproducing by incorporating specified wax into a back coating layer. CONSTITUTION:At least one kind of aliphatic hydrocarbon org. compd. selected from paraffin wax and polyolefin wax is incorporated into a back coating layer 5. Aliphatic hydrocarbon org. compd. such as paraffin wax and polyolefin wax is usually known as an external lubricant and used as a mold release agent in the process of molding polar plastics. This kind of compd. has a long chain of hydrocarbon, which gives low solubility with polar plastics. It appears on surfaces of plastics during solidifying and makes easy releasing from dies. The wax incorporated into the back coating layer prevents contact of the back coating layer 5 to the magnetic layer 3 and prevents transfer and adhesion of the back coat binder to the magnetic layer. Thereby, the obtd. magnetic tape 1 has excellent recording/reproducing qualities free from head clogging.
