摘要： A method for manufacturing a magnetic paint by mixing a resin composition powder as a dispersing binder for a magnetic powder with the magnetic powder, or together with a filler, and grinding the mixture under a high shear stress is disclosed. A magnetic recording medium such as a magnetic disk, etc., prepared by using the magnetic paint, can have a magnetic coating film having a substantially uniform film thickness of not more than 0.9 .mu.m and a surface roughness of not more than 0.05 .mu.m Ra before surface finishing.

摘要： A method for magnetic orientation of a magnetic recording medium using Meissner effect of a superconductor and a system therefor and a magnetic recording medium produced thereby. The magnetic particles of plate hexagonal barium ferrite in the magnetic coating are allowed to orient in the longitudinal direction thereof so that a magnetic recording medium having a magnetic orientation in such direction with the magnetic particles can be obtained.

摘要： The pressure-sensitive resistor comprising an electroconductive elastomer, in which an electroconductive particulate material is dispersed, two electrodes placed on the opposing surfaces of the elastomer, a means for providing a compressive force between the electrodes and a means for adjusting the compressive force, works on a novel principle that the elastomer composite exhibits a positive coefficient in the curve of compression vs. resistance relationship when the compressive force is varied in a region exceeding an inversion point at which the resistance of the elastomer as measured in the direction of compression is minimal. The coefficient in this positive region is smaller than in the ordinary negative region, so that the variable resistance of the resistor can be controlled very delicately together with the decreased contribution of the uncontrollable contact resistance.
摘要翻译：压敏电阻器包括导电弹性体，其中分散有导电颗粒材料，放置在弹性体的相对表面上的两个电极，用于在电极之间提供压缩力的装置和用于调节压缩力的装置的工作基于弹性体复合材料在压缩力与电阻关系曲线中呈现正系数的新颖原理，当压缩力在超过在压缩方向测量的弹性体电阻最小时的反转点的区域中变化时。该正区域中的系数比普通负区域小，因此可以非常精细地控制电阻器的可变电阻以及不可控接触电阻的减小的贡献。
