  • Publication number: 20240191074
    Abstract: A flame-retardant modified-poly(phenylene oxide) resin composition and an article molded therefrom are provided. The flame-retardant modified-poly(phenylene oxide) resin composition provides a flame-retardant modified-poly(phenylene oxide) resin article that has excellent deformation resistance and mechanical properties, along with enhanced product moldability and appearance quality. Accordingly, the flame-retardant modified-poly(phenylene oxide) resin article can be advantageously used as a battery module housing for electric vehicles.

  • Patent number: 10442927
    Abstract: Disclosed is a flame-retardant polyphenylene ether resin composition having high rigidity and high impact strength. More particularly, disclosed is a flame-retardant polyphenylene ether resin composition having high rigidity and high impact strength which enhances environmental stress cracking resistance and impact resistance, compared to general materials, while exhibiting superior mechanical strength such as flame retardancy, tensile strength, flexural strength, flexural modulus, etc. through addition of particularly glass fiber, maleic anhydride-grafted polyphenylene ether, a thermoplastic styrenic elastomer, an ethylene terpolymer and an epoxy resin to a polyphenylene ether resin, and thus, may be used as a material of automobile battery cell modules or electric/electronic components.

  • Patent number: 8833404
    Abstract: The present invention relates to a steel net reinforcement structure which is used for a conveyer belt or a shutter screen. The steel net reinforcement structure comprises: a steel net including hooks projecting from both sides thereof; a reinforcement including a slit cut open along a diagonal direction on both sides thereof; and a steel core which can lock the hooks which are inserted on both inner sides of the reinforcement. The steel net reinforcement structure can be wound conveniently and flexibly while reinforcing strength of the steel net.

  • Patent number: 5729248
    Abstract: A character information processing circuit performs half-blanking by decreasing the gain of a video signal component representing a background screen when various OSD characters, such as a menu, are to be displayed on the screen. Reducing the gain of the background screen enables the OSD characters to be easily distinguished. It should be noted that the background screen is also visible in the region where OSD characters are displayed due to adjustment of the blanking amount of the video signal in the OSD region. The character information processing circuit permits adjustment of the screen state produced in the OSD region by an OSD circuit. A method for generating an optimal OSD display is also described.
