    摘要： Disclosed is a connector contact material that has a small friction coefficient, requires a small insertion force, and moreover does not raise contact resistance while maintaining the properties and insertion operability as a connector. The connector contact material has a coating film comprising the mixture of fluoric resin particles and fluoric oil on the surface of a substrate, wherein the thickness of the coating film is 0.2 to 0.5 μm, and the proportion of the fluoric resin particles to the total amount of the fluoric resin particles and the fluoric oil in the coating film is 20% to 40% in mass, and thereby the connector contact material has a small friction coefficient, requires a small insertion force, and moreover does not raise contact resistance.

    摘要： An iron-based soft magnetic powder for dust core includes an iron-based soft magnetic matrix powder, and arranged thereon in the following order, a phosphate coating and a silicone resin coating. The phosphate coating contains P, Co, Na, and S in combination with at least one of Al and Cs. This iron powder for dust core has superior mechanical strength, in which effective insulation is achieved between iron powdery particles even when the amount of an insulating material is reduced for realizing high-density molding. The iron powder for dust core is also superior in thermal stability, so that electrical insulation is maintained even after a heat treatment at high temperatures.

    摘要： A separator for a fuel cell comprising a titanium alloy substrate containing at least one noble metal element selected from platinum group elements, Au and Ag; and a layer of a mixture formed on the titanium alloy substrate, said mixture comprising the noble metal element precipitated from the titanium alloy substrate and titanium oxide, and said layer having an average thickness of up to 200 nm; wherein the mixture layer on the surface and the titanium alloy substrate have a conductivity in terms of contact resistance as determined by the following method of up to 12 mΩ·cm2. The contact resistance is determined by placing a carbon cloth having an average thickness of 0.3 mm on opposite surfaces of the titanium alloy substrate having the mixture layer formed thereon; sandwiching the titanium alloy material with a pair of copper electrodes via the carbon cloth, the copper electrodes each having a contact area with the titanium alloy material of 1 cm2; measuring voltage drop between the carbon cloths by using a four terminal ohmmeter while pressing the copper electrodes against the titanium alloy material at a surface pressure of 5 kg/cm2 by using a hydraulic press and applying an electric current of 7.4 mA between the copper electrodes; and calculating the contact resistance from the measured value.
