摘要： The use of a Nd-YAG laser or excimer laser enables easy formation of protrusions on a protecting layer and a portion of an opposite surface near the trailing side end thereof and a thin film element. It is thus possible to avoid direct contact between the thin film element and the disk surface, and thus prevent damage to the thin film element and wearing thereof even if a slider and the disk surface repeatedly slide on each other.

摘要： A ferrite plate and a ceramic plate are joined to each other by a glass layer interposed therebetween. The ferrite plate and the ceramic plate thus joined to each other by the glass layer serve as a trailing core in the form of a composite for use in a magnetic head. Only the ferrite plate is exposed on a slidable surface to prevent the trailing core from being deformed or cracked. The trailing core has low inductance for high-density recording to prevent the magnetic head from causing recording/reading errors.

摘要： A core chip for a magnetic head core slider, including a first and a second core member which are bonded together so as to define a coil-winding aperture. The two core members cooperate to provide a gap-forming portion defining a magnetic gap on one side of the coil-winding aperture, and a cut-off portion provided adjacent to the gap-forming portion. The cut-off portion is removed by grinding at the top surface to establish the nominal depth of the magnetic gap. The cut-off portion has a distance marker which extends from the top surface down to the gap-forming portion and which has an end portion adjacent to the gap-forming portion. The end portion is shaped so as to indicate a distance between the top surface and the gap-forming portion, that is, the depth of the magnetic gap, when the cut-off portion is removed to provide a sliding surface of the core chip in which the magnetic gap is open. Also disclosed is a process of fabricating the magnetic head core slider using the core chip.

摘要： An optical unit having an electrooptical element whose optical properties are changed as a function of a voltage applied thereto to modulate an incident light in response to the applied voltage. The optical unit includes a shielding member for electrically shielding at least a portion thereof which includes the electrooptical element from an external electric field. The shielding member protects the electrooptical element from an influence of an external electric field on an electrooptical effect of the electrooptical element. The shielding member may be an electrically conductive member, such as a metallic casing accommodating the electrooptical element, or an electrically conductive layer covering a housing accommodating the element.

摘要： A magnetic head core including two ferrite blocks which are bonded together so as to form a magnetic path and which includes respective two protrusions protruding from the opposed surfaces thereof. The protrusions have opposed end faces cooperating with each other to define a magnetic gap therebetween. The opposed surfaces of the two ferrite blocks cooperate with the two protrusions, to define two cutouts formed on opposite sides of the magnetic gap, such that a spacing provided between the opposed surfaces by each cutout is larger than an amount of the magnetic gap. The cutouts define an effective width of a track of the head core in which the magnetic gap is open. Each protrusion has two side surfaces inclined at an angle of 25.degree.-75.degree. with respect to its end face. Each cutout is defined by at least one pair of opposed ridges which are formed on the opposed surfaces of the two ferrite blocks, respectively, such that each ridge is disposed on each side of a corresponding one of the two protrusions.

摘要： An optical device including an optical bench and a plurality of optical elements. The optical bench has first and second supporting sections, separated from each other, each having at least two supporting surfaces. The optical elements secured to the first and second supporting sections have cylindrical bodies, so that these optical elements contact the sections only by lines. Therefore, the relative positions of each optical elements in the optical device are maintained for a long time without being affected by temperature variation in the atmosphere surrounding the optical device.
