Abstract: A granule-type magnetoresistive material is used to form a MR component, which is equipped in a magnetic head, or the like. When placing the magnetoresistive material in the external magnetic field, the electric resistance is altered responsive to a variation of the external magnetic field. In order to increase a magnetic-field sensitivity, the magnetoresistive material is composed of an alloy whose atomic composition is expressed by a chemical formula of (Co.sub.1-x Fe.sub.x).sub.y Ag.sub.1-y, where 0.45.ltoreq.x.ltoreq.0.55 and 0.24.ltoreq.y.ltoreq.0.35; or another chemical formula of (Co.sub.1-x Fe.sub.x).sub.y (Ag.sub.1-z Cu.sub.z).sub.1-y, where 0.45.ltoreq.x.ltoreq.0.55, 0.24.ltoreq.y.ltoreq.0.35 and z.ltoreq.0.14.

Abstract: In production of an optomagnetic recording medium having a porous anode oxidized coat on a base plate, a thin film of magnetic material of high saturated magnetization is developed after grinding and etching following formation of the anode oxidized coat in order to increase the effective reflection plane, thereby greatly raising accuracy of detection of the polarization angle at reading-out of signals.

Abstract: In construction of a magnetic recording material having overlaid anodic oxide layers and well suited for perpendicular magnetic recording, a substrate is made of a hard material and Al predominant layers of 0.1 to 2 .mu.m thickness and formed on the substrate as a base for the overlaid anodic oxide layers for improvement in mechanical properties with acceptable magnetic recording characteristics.

Abstract: In a control system for a thermal transfer color printer capable of color print, first and second sensors for detecting a printing paper are disposed before and after a platen roller for carrying the printing paper, so that when the printing paper is carried and detected by the first sensor, the printing paper is changed to a low speed and at the same time a thermal head is pressed against the printing paper through an ink film and when the printing paper is detected by the second sensor, the thermal head is supplied with a print signal for color printing.

Abstract: A granular composition for use in the agricultural and horticulture fields is prepared by mixing an active ingredient, such as an insecticide, fungicide or herbicide and a solvent or a binder with a carrier consisting of 0-30% of particles larger than 149 .mu. (100 mesh), 40-90% of particles between 149 .mu. (100 mesh) and 46 .mu. (300 mesh) and 10-30% of particles smaller than 46 .mu.. Finely divided particles of moisture-absorbing substances may be added when the carrier has been moderately granulated in the course of the production process. The composition is suited for spraying by helicopters or multi-nozzle hoses on dusters, for example.
