IPC: G11B9/06
Filed: 1984-01-28
Abstract: PURPOSE:To obtain a recording medium having high performance with a reduced swelling degree by using an electrostatic capacity type information signal recording medium having a conductive resin composition containing a conductive material and the thermoplastic resin having a specific grain size distribution with specific limitation. CONSTITUTION:No swelling is virtually produced due to the hardened grains when the polyvinyl chloride resin of small bulk density is used. It is known, for example, that the bulk density of the polyvinyl chloride is prescribed by a 200 mesh pass factor. Thus the swelling phenomenon due to the hardened grains is reduced with >=15% of th 200 mesh pass factor. Then the 200 mesh pass factor is set preferably at >=50% and more preferably at >=80%. The polyvinyl chloride resin of fine grain sizes is obtained by controlling a polymerization method or gathering only the resin of fine gain sizes after polymerization or obtaining the polyvinyl chloride resin of large grain sizes and crushing it into fine powder by a mechanical means, etc.

Filed: 1981-02-02
Abstract: PURPOSE:To improve the moisture resistance of a paste for attaching a pellet by setting the electric conductivity of the extracted liquid of the paste to the same degree as or lower degree than that of a molding resin. CONSTITUTION:A pellet 16 is mounted on a tab 13 of a lead frame 10 via a paste 14 for attaching the pellet. The electrode of the pellet 16 is electrically connected to the inner lead of the lead frame 10 via a wire 18. After the wire 18 is bonded, the pellet is molded and is sealed in a package 20. When the electric conductivity of the extracted liquid of the paste 14 becomes less than approx. 200muv/cm, the aluminum corrosion improper rate of the paste 14 is reduced t considerably low value. Accordingly, when the electric conductivity of the extracted liquid of the paste 14 is set to the same degree as or lower degree than that of a molding resin, the moisture resistance of the paste 14 can be improved, thereby preventing the hydrolysis. Thus, the aluminum corrosion rate can be suppressed to sufficiently low value.

Abstract: PURPOSE:To balance currents among other normal power sources and carry on parallel operation without being affected by a power source at a stop by comparing the output currents of parallel power sources with a mean current, and controlling and balancing the respective output currents.
