Title: Magnetic recording medium and its production
Inventor: SAITO MITSUYOSHI
IPC: G11B5/72
Filed: 1985-08-30
Abstract: PURPOSE:To maintain always good lubricity over a long period of time by preliminarily impregnating a lubricating oil into non-woven fabrics facing surfaces on which lubricating oil films having a specific thickness are formed. CONSTITUTION:Both faces of a magnetic recording medium body 1 contact slidingly with the non-woven fabrics 5, 6 when the magnetic recording medium body 1 rotates. As a result, the lubricating oil impregnated to the non-woven fabrics 5, 6 and the lubricating oil coated on both faces of the body 1 are transferred and received to and from the body 1 and the non-woven fabrics 5, 6 and attain an equil. state in an extremely short period. Since the non-woven fabrics 5, 6 are in sliding contact with the surfaces of the body 1 at all times, the thin and uniform lubricating oil film is maintained for a long period of time on the surfaces of the body 1. Frictional force is extremely small and stable if the thickness of the lubricating oil film is <=300Angstrom . On the other hand, the formation of the film to <=10Angstrom  thickness is extremely difficult. The film thickness of the lubricating oil is, therefore, preferably 10-300Angstrom .

Abstract: PURPOSE:To stably and efficiently dry a crystal of erythritol useful as a low- calorific sweetener, especially a crystal having relatively large diameter from a water-content of 1-10wt.% to <=0.15wt.% without deteriorating the crystalline state. CONSTITUTION:A crystal of erythritol having a water-content of 1-10wt.% (generally 2-8wt.%), especially a relatively large crystal having particle diameter of 500-700mum is dried to recover the erythritol crystal having a water-content of <=0.15wt.%. In the above process, a fluidized drying is used as the drying means and the temperature of the gas for the fluidized drying is controlled to 10-60 deg.C (preferably 40-55 deg.C) until the watercontent of the crystal is lowered to <=0.5wt.% (preferably <=0.15wt.%). There is no coagulation and agglomeration of crystals during the drying process even in the case of crystals having large particle size and the crystal can efficiently be dried to the prescribed water- content.

Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To accurately reproduce a demodulation signal by providing a signal generation means, first and second mixing means, a differentiation means, a switching means turning a signal forward or backward and a filter means. SOLUTION: A frequency correction means 22 detects a DC offset (x) to control the oscillation frequency of the signal generation means 6 to make the offset (x) become zero. In order to detect the offset (x), a demodulation signal Δω is eliminated through the use of an averaging means in a period longer than the fluctuation period of the demodulation signal Δω to take out only (x). The oscillation frequency of the means 6 is controlled through the use of the means 22 so as to eliminate the deterioration of an eye pattern. In addition, first LPF 4 and second LPF 9 are band variable type filters so that an S/N ratio is improved by controlling the oscillation frequency of the means 6 to a direction, which makes a frequency difference (x) zero, and then narrowing the band width of LPFs 4 and 9.
