Title: Magnetic head
Inventor: OJI TOSHIO
IPC: G11B5/127
Filed: 1987-01-30
Abstract: PURPOSE:To improve joining force between magnetic cores forming a working gap and an erasing characteristic by forming a magnetic metallic film to at least one face of the cores and a glass film essentially consisting of PbO, B2O3, Al2O3, and SiO2 to the one core surface on the opposite side in such a manner that the one face formed with the glass is positioned on the escape side of a magnetic recording medium. CONSTITUTION:The low melting glass essentially consisting of PbO, B2O3, Al2O3, and SiO2 is disposed to at least the joint surfaces of the approximately C- or I-shaped cores 12, 11 to increase the direct adhesive power between the joint surfaces thereof. A protective film consisting of Zr, Cr, etc., is provided on the magnetic metallic film 5 which is in contact with the glass 7 and forms one end of the working gap and, therefore, the diffusion reaction with the glass is lower in comparison with a ferrite material. The ferrite material side is consequently deteriorated extremely gently without deteriorating the magnetic characteristics of the magnetic metallic film. The joint strength near the working gap is thereby increased and the erasing characteristic is improved.

Title: Method for illuminating light visual field and dark visual field
Inventor: YOSHIDA HIROSHI
IPC: G03B15/02
Filed: 1993-01-13
Abstract: PURPOSE:To obtain the merits of both the illumination of light visual field and the illumination of dark visual field by which not only the defect of a surface but also the defect of a bottom part can be caught by radiating light to a boundary between the light visual field and the dark,visual field, that is, in such a way that an illuminating angle is a specified angle against a direction perpendicular to the upper surface of a processed substance. CONSTITUTION:The light 1 from a light source irradiates a substance to be illuminated 2 within a range from 5 deg. to 15 deg., and obtained reflected light 3 is allowed to get to the peripheral part of a lens 4 for photographing. In such a case, when the illuminating angle is set within 5 deg., the illumination of light visual field that the reflected light 3 irradiating the substance 2 directly enters the lens 4 is attained, whereby the defect of the bottom part is caught but the defect of the surface is not caught because it is not distinguished from a normal part. On the contrary, when it is set to >=15 deg., the illumination of dark visual field that the reflected light 3 irradiating the substance 2 does not directly enter the lens 4 is attained, whereby the defect of the surface is caught but the defect of the bottom part is not caught because it is hidden. Therefore, not only the defect of the surface but also the defect of the bottom part are caught by setting the illuminating angle to 5-15 deg..

Filed: 1990-01-29
Abstract: PURPOSE:To make improvement in the contrast of exposing light to a 1st resist by subjecting the 1st resist to exposing via a contrast increasing layer with a patterned 2nd resist as a mask. CONSTITUTION:After the lower layer resist 2 is formed by spin coating on a substrate 1, the contrast increasing layer 10 consisting of a full-surface light fadable material is formed by spin coating on the lower layer resist 2. The upper layer resist 3 is then formed by spin coating over the entire surface on the contrast increasing layer 10. Further, the this resist is irradiated with upper layer exposing light 5 via an exposing mask 4 and is then developed, by which the upper layer resist patterns 3a are formed. The contrast increasing layer 10 is thereafter irradiated with lower layer exposing light 6 via the upper layer resist patterns 3a. The contrast of the exposing light to the 1st resist improves in this way even if the absorption of the exposing light in the 2nd resist is imperfect.
