  • Publication number: 20210222031
    Abstract: [Object] The present invention provides a curable resin composition useful for imparting high durability and adhesion to a substrate such as a metal. [Solution] A curable resin composition is prepared by combining a polyamide-based resin (A) having an amino group, a blocked polyisocyanate (B), and an epoxy compound (C). The polyamide-based resin (A) contains a polyamide-based resin (A1) having a melting point of 170° C. or higher and a polyamide-based resin (A2) having a melting point of 150° C. or lower. The mass ratio of the polyamide-based resin (A1) and the polyamide-based resin (A2) is, in the form of the former/the latter, from 65/35 to 35/65.

  • Publication number: 20210198541
    Abstract: Provided are a curable resin composition having high durability and adherence to a base material such as a metal, a molded composite member formed by coating the base material with the curable resin composition and performing resin molding, and a production method for the same. The curable resin composition contains a polyamide-based resin, a blocked polyisocyanate, and an epoxy compound, and the polyamide-based resin has an amino group concentration from 20 to 300 mmol/kg, and has a water absorption of 1 mass % or less determined by a water absorption test specified by ASTM D570. The polyamide-based resin has a C8-18 alkylene chain and has a melting point from 160 to 250° C. Per 1 mol of amino groups of the polyamide-based resin, a proportion of isocyanate groups of the blocked polyisocyanate is from 1.5 to 5 mol, and a proportion of epoxy groups of the epoxy compound is from 0.1 to 0.8 mol.

  • Patent number: 10519338
    Abstract: A resin powder containing an aromatic polyetherketone resin (e.g., a polyetheretherketone) is deformed into a plate-like form, and the resulting powder is used as a resin powder for a coating material. The plate-like resin powder may have an average thickness of, for example, not more than 2 ?m. The coating material may contain a dispersing agent or may be dispersed in a dispersion medium, such as water. The coating material may particularly be used as a coating material for covering a metal substrate. The plate-like resin powder, which comprise an aromatic polyetherketone resin, allows formation of a coating layer which has a high adhesion to a substrate and in which the generation of pinholes is efficiently prevented or reduced.

  • Patent number: 10033201
    Abstract: A battery controller 10 outputs a voltage sampling and holding command signal to an integrated circuit CCn located at an upstream end of cascade connection of integrated circuits CC1-CCn such that integrated circuits CC1-CCn sample and hold output voltages of unit cells 1 grouped into battery modules M1-Mn. The battery controller 10, after transmission of the voltage sampling and holding command signal, outputs a transmission command signal to the integrated circuit CCn at the upstream end of the cascade circuit to transmit output voltages of the unit cells 1 held in the integrated circuits CC1-CCn to the battery controller 10. As a result, a time lag in the detection timings of output voltages of the unit cells 1 of the battery modules M1-Mn can be decreased.

  • Publication number: 20160096946
    Abstract: A resin powder containing an ultraviolet scattering agent (such as a titanium oxide particle or a zinc oxide particle) is deformed into a plate-like form. The ultraviolet scattering agent may include, for example, a titanium oxide particle or zinc oxide particle having an average particle diameter of not more than 100 nm. A resin contained in the resin powder may particularly be a thermoplastic resin (e.g., a polyamide resin). The plate-like resin powder may be a powder obtainable by deforming resin particles, each containing the ultraviolet scattering agent, into a plate-like form. The resulting resin powder has an excellent ultraviolet scattering function.

  • Publication number: 20120046893
    Abstract: A battery controller 10 outputs a voltage sampling and holding command signal to an integrated circuit CCn located at an upstream end of cascade connection of integrated circuits CC1-CCn such that integrated circuits CC1-CCn sample and hold output voltages of unit cells 1 grouped into battery modules M1-Mn. The battery controller 10, after confirming that the voltage sampling and holding command signal has been transmitted to an integrated circuit CC1 located at a downstream end of the cascade connection, outputs a transmission command signal to the integrated circuit CCn at the upstream end of the cascade circuit to transmit output voltages of the unit cells 1 held in the integrated circuits CC1-CCn to the battery controller 10. As a result, a time lag in the detection timings of output voltages of the unit cells 1 of the battery modules M1-Mn can be decreased.
