    Abstract: PROBLEM TO BE SOLVED: To provide a dehumidifier which can be fixed to a small space of the cover of a disc drive and can sustain the inner humidity of the disc drive at a low level permanently, and to perform dehumidification stably without forming any dew on the inside or the outside of the disc drive by controlling the dehumidifier based on the inner humidity or the temperature conditions on the inside and the outside of the disc drive. SOLUTION: The dehumidifier comprises glass fibers 55 disposed to penetrate the cover 3 of a hard disc drive HDD and extending over the inside and outside thereof, and a heating member 53 disposed on the outside of the HDD wherein the glass fibers 55 on the outside are bonded to the heating member and heated. Furthermore, a cooling member is provided on the inside of the HDD and the glass fibers on the inside are bonded to the cooling member. Means for circulating air touching a heating part and cooling part is also provided.

    Abstract: PURPOSE: To embody high-density recording by a ferrite head by joining the bonding bumps of two chips, thereby forming a winding coil. CONSTITUTION: The chip 1 is formed with multilayered wirings 10 and the bonding bumps 13 on an Si substrate 12. The chip 2 is formed with the multilayered wirings 10 of copper, conducting paths 14 penetrating the substrate, the bonding bumps 13 and grooves 6 for crossing the ferrite cores. The bonding bumps 13 are composed of a low melting solder and are melted by a heat treatment at about 150 deg.C. The chips 1 and 2 are joined by melting the bonding bumps 13, by which the winding coil is formed.
