Patent JP-S619826-A (JP)
Title: Magnetic recording medium
Inventor: SASAKI KUNITSUNA
IPC: C09D127/04
Filed: 1984-06-25
Abstract: PURPOSE:To obtain the titled recording medium having sufficient mechanical strength with appropriate flexibility, durability, and excellent traveling properties and with less release of powder by incorporating a urethane resin having a yield point, at least on between a vinyl chloride and a phenoxy resin, and magnetic particles into a magnetic layer. CONSTITUTION:A urethane resin having a yield point is used as the component of a resinous binder. The elongation is extremely small below the yield point even when strenssed, and hence proper hardness is given to the urethane resin. The resin elongates with an increase in stress above the yield point without being broken. The yield point important to the performance of the urethane resin is in the stress range 50-600kg/cm<2>, or preferably 100-500kg/cm<2>. Moreover, since a vinyl chloride copolymer and/or a phenoxy resin are incorporated as the other resinous binder components to increase the hardness of the magnetic layer and the dispersibility of the magnetic powder, the strength of the magnetic layer is further improved. As the surface area of the magnetic powder of the magnetic layer is regulated to >=30m<2>/gr, the reproduction output and S/N are remarkably increased.

Abstract: PURPOSE:To easily confirm a fault in fitting by connecting a loop connection type harness between a connector for data communication and a concentrating connector for a fault diagnostic device connection and also connecting the harness to a display means, and warning the fault in the contacting of the connector on a display means. CONSTITUTION:In an instrument panel 7, a warning lamp 7a is connected between a power source and the ground. If connectors 4a-4c for data communication of respective on-vehicle electronic controllers 1a-1c become faulty in fitting, a current flows to the warning lamp 7a on the instrument panel 7 to inform the driver of abnormality. Further, the controllers 1a-1c monitor the logical levels of loop connection type harnesses 6a-6c for fitting defect detection through the connectors 4a-4c at all times. Consequently, when a high-order on-vehicle electronic controller including itself, e.g. 1b detects the logical level 1, the fault in the fitting of the data communication connectors 4a and 4b of the on-vehicle electronic controllers 1a and 1b can be known.
