Title: Production of coating type magnetic recording medium
Inventor: CHIBA KATSUYOSHI
IPC: G11B5/842
Filed: 1987-01-28
Abstract: PURPOSE:To enhance the effectiveness of the denseness of magnetic powder and to obtain a magnetic recording medium having high S/N by subjecting the undried magnetic recording medium to vacuum drying under a reduced pressure. CONSTITUTION:A disk 1 on which undried magnetic coated films 2a, 2b are coated is charged into openable/closable vessels 3a, 3b (the pressure in the vessels is reducible) which permits charging and taking out of the disk. The inside of the vessel is then evacuated through a pipe 5 to a vacuum. The magnetic particles in the magnetic coated films are effectively compacted by evacuating the vessel inside quickly to a vacuum. Since the undried magnetic coated films are subjected to the vacuum treatment (reduced pressure treatment) in such a manner, the denseness of the magnetic powder of the recording medium is enhanced. Surface roughening is prevented and an electromagnetic effect is enhanced by effectively acting the treatment.

Title: Method for inhibiting oxidation of steel material
Inventor: UEHARA TAKUO
IPC: C21D1/72
Filed: 1991-01-18
Abstract: PURPOSE:To inhibit the oxidation of a steel material without causing film boiling by applying or spraying a soln. of the copolymer contg. ethylene oxide and propylene oxide as the monomers on a high-temp. steel material. CONSTITUTION:The polymer soln. is separated at >=100 deg.C into a polymer liq. and water, and mixed with water at <100 deg.C to form a polymer soln. Consequently, the film of the polymer liq. is formed around the steel material at >=100 deg.C to cover the entire steel material, and film boiling (generation of steam film) is hardly caused even at >=500 deg.C. Meanwhile, since the oxidation inhibitor for the soln. has an OH group in the monomer, the OH group in the polymer film covering the steel material reacts with the iron to cause reduction when the soln. is applied on the steel material, and the yield of Fe3O4 is increased. Accordingly, the oxidation of the steel material is inhibited, the adhesion of the oxide scale to the steel material is improved, and the trouble caused by the release of scales is prevented when the steel material is worked.

Title: Level discrimination processing system
Inventor: TANAKA SEIGO
IPC: G05B11/36
Filed: 1983-02-03
Abstract: PURPOSE:To perform the level discrimination without discrimination errors, by increasing or reducing the level of a discrimination level signal in the direction opposite to the increase and reduction direction of a signal to be compared when the signal to be compared has the same level as the discrimination level signal in one section where the signal to be compared is increased or reduced. CONSTITUTION:A processing circuit 9 receives a detection signal (a) from an oxygen concentration detector 8 and allows a discrimination level signal (b) to lag behind the signal (a) in phase on a basis of the signal (a) to set the signal (b) to a level which can discriminate rich and lean at the same period. When it is found that a discrimination signal which is attained by level discrimination of signals (a) and (b) and indicated an air fuel ratio is lean, the level of the signal (b) is raised by alpha at a point P1 crossing the signal (a). Thus, rich/lean discrimination errors are prevented in the section where the discrimination signal is in the low level. When it is found that the discrimination signal is rich, the level of the signal (b) is reduced by alpha at a point P2 crossing the signal (a). Thus, rich/ lean discrimination errors are prevented in the section where the discrimination signal is in the high level.
