Patent JP-H0287414-A (JP)
Title: Electric wire for audio appliance
Inventor: KUROSAKA AKITO
IPC: H01B7/00
Filed: 1988-09-22
Abstract: PURPOSE:To enhance the sound quality such as the sense of clearness and the expansiveness of sound field by constituting a wire for audio appliance from a conductor obtained from Cu base material, which has a specific oxygen content and a perfect softening temp. and is subjected to perfect softening treatment. CONSTITUTION:A Cu base material with oxygen content below 20ppm and with a perfect softening temp. below 150 deg.C is subjected to perfect softening treatment to provide a conductor, which is used for a wire for audio appliance. When the oxygen content exceeds 20ppm, the oxygen in the Cu base material reacts with impurities in the Cu base material to produce oxides (Fe2O3, SiO2, etc.), and also reacts with Cu in the base material to produce copper oxide, and it becomes easier for these oxides to educt at crystal boundaries. This increases difference between the electric resistance of Cu monocrystals and the electric resistance at the crystal boundaries, which sinks the sound quality very much. This lowering of the perfect softening temp. can enlarge recrystallized grains easily by means of annealing, and the grain boundary areas can be decreased. A plurality of such conductors are twined together into a strand, which is covered with insulation to accomplish a wire for audio appliance.

Title: Production of magnetic recording medium
Inventor: NIIMI HIDEAKI
IPC: G11B5/735
Filed: 1987-09-24
Abstract: PURPOSE:To eliminate the defects of a magnetic tape and to improve corrosion resistance by coating at least a back coating agent or lubricating agent on the rear face of a high-polymer film substrate, then providing a thin ferromagnetic metallic film on the front face of this high-polymer film substrate. CONSTITUTION:The back coating agent or lubricating agent is first coated on the rear face of the high-polymer film substrate prior to provision of a magnetic layer on the high-polymer film substrate. The magnetic layer is thereafter formed on the front face of the high-polymer film substrate. Arrangement is so made that the produced magnetic recording medium is never passed between rollers after the formation of said magnetic layer. A lubricating layer is once provided on the rear face of the high-polymer film substrate and is laminated on the magnetic layer by transferring said layer in the case of a need for laminating the lubricating layer on the magnetic layer. The pressurization of the magnetic layer between the rollers after the formation of the magnetic layer is thereby averted and, therefore, the room for the generation of defects such as cracks in the magnetic layer is entirely eliminated.
