Title: Magnetic head
Inventor: KOBAYASHI HIDEO
IPC: G11B17/32
Filed: 1988-10-20
Abstract: PURPOSE:To diminish the spacing and to enable the stable contact with a recording medium by making the area of a sole with a core smaller than the area of an opposite sole which is opposite via the recording medium to the former sole and arranging the edges of each sole not to be positioned coincidently opposite to each other. CONSTITUTION:A length of the sole 3 with the core is remained unchanged, but its width A is made smaller than a width B of the opposite sole 4 which is opposite to the sole 3 with a space for passing the recording medium 5 between them, and its edges of both sides forming the width A are disposed to be shifted from the edges of the sole 4. By shifting these two edges, deformation of the medium 5 due to an aerodynamical cause is diminished, thus making the spacing smaller to such an extent. And, by making the area of the sole 3 smaller, the gap for recording and reproducing can be more close to the medium 5 to pass through. By this method, the excellent recording and reproducing can be carried out without increasing the load of a head even if the gap length is shortened.

Title: Paste with ag or ag alloy base
Inventor: INAGE KENGO
IPC: C04B37/02
Filed: 1987-10-22
Abstract: PURPOSE:To prevent carbon residue from remaining at the time of firing of paste with an Ag or Ag alloy base printed on a substrate by adding silver chromate or silver dichromate to the paste. CONSTITUTION:When the metal filler in paste is Ag, carbon can be removed at the time of firing by previously oxidizing a proper amt. of Ag. When the filler is an Ag alloy, silver chromate or silver dichromate powder is added to prevent carbon residue from remaining at the time of firing because it is difficult to oxidize only Ag. The resulting paste has low natural properties and high safety, and when the paste is printed on a substrate and fired, no carbon residue remain.

Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To improve an isolation characteristic in a state where a pattern area per chip of one bit is reduced and to miniaturize and integrate the whole circuit. SOLUTION: A capacitor constituting HPF 21 and LPF 22 is substituted for FEFs 211, 212 and 223. At the time of forming the HPF or the LPF, the FETs 211, 212 and 223 are set to an off state.
