  • Patent number: 11514945
    Abstract: A lubricant for a magnetic recording medium capable of forming a lubricant layer having excellent adhesion to a protective layer is provided. A lubricant for a magnetic recording medium contains a fluorine-containing ether compound in which a group having an ethylenic carbon-carbon double bond is disposed at one or both terminals of a perfluoroalkyl polyether chain. It is preferable that the group having the ethylenic carbon-carbon double bond is disposed at one terminal of the perfluoroalkyl polyether chain, and a hydroxyl group is disposed at other terminal. It is preferable that the lubricant for a magnetic recording medium contains a compound in which one or more functional groups selected from a hydroxyl group, an amino group, an amido group and a carboxyl group is disposed at one or both terminals of a perfluoroalkyl polyether chain.

  • Publication number: 20220308206
    Abstract: A vehicle exterior part is configured to be arranged frontward of a millimeter wave radar device with respect to the transmission direction of millimeter waves. The vehicle exterior part includes an ornamental body, a light source that emits light, and a light diffuse reflection member. The light diffuse reflection member is millimeter wave-transmissive and diffuses and reflects light. The ornamental body includes a base and an ornamental layer. The base is millimeter wave-transmissive and diffuses and transmits the light. The ornamental layer is millimeter wave-transmissive and arranged frontward of the base with respect to the transmission direction. The light source, the ornamental body, and the light diffuse reflection member are arranged so that the light emitted from the light source is diffused and reflected by the light diffuse reflection member and directed toward the base.
