Abstract: PURPOSE: A manufacturing method is provided to obtain a powder for a soft magnetic core material easy in composition control and excellent in workability, soft magnetic features and DC superposing features. CONSTITUTION: Fe and Fe-Si alloy or Fe and Si are melted in the first step to have a composition of Si 5 to 8wt% and Fe as a residual. A silicon steel powder is prepared via gas injection or water injection in the second step. The silicon steel powder obtained in the second step is machined using a ball mill, an attrition mill, a load mill and the like in the third step. The machined silicon steel powder is heat treated at the atmosphere of hydrogen, nitrogen or a mixture gas hydrogen and nitrogen at a temperature of 700 to 1000deg.C for 4 to 15 hours. Heat treatment removes stress in the alloy powder to produce crystal grains free from residual stress and to decrease shearing between the powder and insulation layers in manufacturing a soft magnetic core using the powder.

Abstract: PURPOSE: An optical pickup is provided to reduce the price and to avoid the generation of astigmatism although two plate splitters are used. CONSTITUTION: An optical pickup comprises a grate plate(1) installed to generate astigmatism when the beam emitted from a laser diode(50) passes through, a first plate splitter(2) removing the astigmatism when the beam passing the grate plate is reflected on, a second plate splitter(3) installed to avoid astigmatism when the beam reflected on the first plate splitter passes through, and another laser diode(51) installed in an angle avoiding the generation of astigmatism in the second plate splitter. The beams passing through the first and second splitters are irradiated to a mirror(55). The astigmatism generated in the grate plate is offset by the astigmatism generated in the first plate splitter. The beams irradiated to the mirror are irradiated to a collimate lens(56) and an objective lens(57). Thus, the beams are reflected while being irradiated through the objective lens.
