  • Publication number: 20180057685
    Abstract: Provided is a resin composition having excellent flame retardance, molding processability, and post-heat aging flame retardance. A flame-retardant resin composition contains: (A) a polyphenylene ether; (B) at least one thermoplastic resin selected from the group consisting of (B-1) a polystyrene resin, (B-2) a polyamide resin, (B-3) a polypropylene resin, and (B-4) a polyphenylene sulfide resin; and (C) a flame retardant. The (A) component has a content of less than 50 mass % when the flame-retardant resin composition minus ash content is taken to be 100 mass %. The flame-retardant resin composition has a flame retardance level of V-0 as measured by a UL 94 vertical burning test. A molded article formed from the flame-retardant resin composition exhibits a rate of change of chloroform-insoluble content of no greater than 15 mass % before and after being subjected to aging in which the molded article is left for 1,000 hours at 150° C. in an atmospheric environment.

  • Patent number: 9374494
    Abstract: The present invention relates to a recording apparatus and method, a reproducing apparatus and method, and a program that make it possible to photograph and record a still image and moving images before and after the still image as well. In step S1, when a still-image-with-moving-image photographing mode is set, moving image temporary storage is started. When a shutter is depressed in step S2, in step S3, a photographed still image is recorded and one moving image is generated from the moving image before the still image stored in step S1, a moving image obtained by converting the photographed still image, and a moving image photographed after the depression of the shutter and the one moving image generated is recorded. Therefore, the moving images before and after the still image are recorded together with a high-definition still image.
