摘要： PURPOSE:To perform high-density recording and reproducing operation excellently by using the main magnetic pole of a one-side access main magnetic pole excitation type perpendicular magnetic head for magnetic recording and reproduction even as an electrode for detection variation in electrostatic capacity value in common. CONSTITUTION:When the whole connection line 10 connected to the main magnetic pole 1 of the one-side access main magnetic pole excitation type perpendicular magnetic head for perpendicular magnetic recording and reproduction constituted so that the main magnetic pole is used even as the electrode for detecting variation in electrostatic capacity value is made of a magnetic material layer, an auxiliary magnetic pole 2 is so sized to nearby the constitution part of a magnetic path 9 and the other part 13 is made of a nonmagnetic material, e.g. glass, so that no leakage flux is produced between the end part of the connection line 10 and the auxiliary magnetic pole 2. Further, the auxiliary magnetic pole 2 is made of a magnetic material having too high resistivity to operate as the electrode, e.g. NiZn ferrite, and consequently a return path for excellent magnetic flux is obtained. Consequently, perpendicular magnetic recording and reproducing operation with high efficiency and high sensitivity is easily realized.

摘要： PROBLEM TO BE SOLVED: To provide a heat conductive sheet which, when a radiating plate is fixed on the back of a display panel through the heat conductive sheet, improves a coefficient of thermal conductivity by maintaining the substantial adhesion area by letting escape air bubbles involved in these interfaces and which excels in repair characteristics in the case of replacing.
SOLUTION: The heat conductive sheet is the one wherein a heat conductive base material containing a heat conductive filler and an adhesive surface layer consisting of a thermoplastic resin emulsion are laminated and wherein the adhesive surface layer has pores communicating with the side through capillary tubes. The pores of the surface layer of the heat conductive sheet are impregnated with an aqueous solution containing a surfactant or a like solution to remove the sheet from the laminated display panel.
