Title: Recording reseparation/composition type magnetic head
Inventor: KOYAMA NAOKI
IPC: G11B5/31
Filed: 1989-02-08
Abstract: PURPOSE:To obtain satisfactory recording characteristic by setting the dimension of a magnetic layer in the width direction of a track shared as the magnetic poles of both heads and a magnetic shielding layer at the upper part of the layer differently from that at the lower part in a film thickness direction. CONSTITUTION:A lower magnetic shielding layer 2 is laminated on a head substrate 1, and a magneto-resistance effect element 4 is laminated via an insulation layer 3, and following that, an upper magnetic shielding layer 6 is laminated via an insulation layer 5. At this time, working such that the dimension of the lower part is formed equivalently to that of the magnetic shielding layer 2, and the dimension of the upper part equivalently to that of a magnetic pole 7 is applied. Furthermore, a conductor layer 9 which becomes a coil is laminated on the layer 6, and the magnetic pole 7 is laminated via an insulation layer 10. Namely, the dimension of the upper part is set differently from that of the lower part of the magnetic layer by providing a tapered part or stage 16 on the cross-section of the magnetic layer. In such a way, recording bleeding generated at the end part of the magnetic pole of a recording head can be suppressed, and off-track overwrite characteristic can be improved, and also, cross-talk between the tracks can be reduced.

Title: Prevention of thermal damage and fire of semiconductor integrated circuit device
Inventor: FUJINAGA MASATO
IPC: H01R33/76
Filed: 1988-02-09
Abstract: PURPOSE:To prevent a fire by inserting a shape memory alloy between a semiconductor integrated circuit(IC) and a socket. CONSTITUTION:A shape memory alloy 7 is inserted between an IC package 1 and a socket 3. Accordingly, when an IC is deteriorated or a design mistake exists in the IC, an abnormally large current flows, the IC generates heat. When the temperature of the package 1 rises, its heat is transferred to the alloy 7. When the temperature becomes the deforming temperature or higher of the alloy 7, the alloy 7 is elongated thereby to operate to draw a conductor pin 4 from the socket 3, thereby eliminating the supply of power to the IC. Thus, the temperature rise is prevented. In this manner, it can prevent a fire from occurring.
