Title: Pad for magnetic recording medium
Inventor: YANAGI MICHIO
IPC: G11B23/087
Filed: 1984-05-29
Abstract: PURPOSE:To prevent the material coated on a magnetic recording medium and other materials from sticking to the sliding surface of a magnetic head and to maintain satisfactorily the electromagnetic conversion characteristic of the magnetic head over a long period of time by impregnating an org. oil diluted with an org. solvent in a pad. CONSTITUTION:The org. oil diluted with the org. solvent is impregnated in the pad 3. The org. oil which consists of moleculars having a polarity (for example, RnCOOH, R is an alkyl group) and non-polar molecules, which polar molecules adsorb and orient on and to the sliding surface side and which non-polar molecules have the effect of decreasing the free surface energy of the sliding surface is preferred. Such oil is exemplified by metallic soap consisting of the metallic salt of a higher fatty acid; the ester of the higher fatty acid; higher alcohol, etc. The reason for diluting the org. oil with the org. solvent lies in that the org. oil is made more easily impregnatable in the pad 3. The org. solvent is exemplified by an arom. hydrocarbon; arom. hydrocarbon chloride; aliphat. hydrocarbon chloride such as methane, ethane and ethylene deriv.

IPC: G11C11/41
Filed: 1994-04-22
Abstract: PURPOSE: To prevent the deviation of a timing signal in various parts of a memory by locally generating an ATD signal in an integrated circuit memory. CONSTITUTION: A memory 110 having the section of a memory cell uses ATD for generating a necessary timing signal and includes an ATD generator 189, the first adder circuits 180-183 and local adder circuits 185-187.
