  • Patent number: 10099089
    Abstract: An object of the present invention is to provide a golf ball resin composition having an excellent rebound resilience. The present invention provides a golf ball resin composition containing an ionomer resin as a resin component. In a DSC measurement (a measuring atmosphere: a nitrogen atmosphere, a measuring temperature range: from ?50° C. to 150° C., and a temperature rising rate: 10° C./min) of the golf ball resin composition of the first embodiment, a first endothermic peak and a second endothermic peak appear, and a peak top temperature (Ti) of the first endothermic peak is equal to or lower than a peak top temperature (Tm) of the second endothermic peak and the peak top temperature (Ti) ranges from 60° C. to 70° C.

  • Patent number: 9206310
    Abstract: A modifier for resin has an average particle size of 20 ?m or more, wherein particles having an average particle size of 10 ?m or less account for less than 30% by mass of the modifier, and particles having an average particle size of 10 ?m or less account for 30% by mass or more of the modifier after irradiating the modifier with ultrasonic wave of 40 W for 5 minutes. Also a resin composition comprises 1 to 40% by mass of the modifier for resin and 99 to 60% by mass (the total amount of both components is 100% by mass) of a thermoplastic resin or a curable resin, and a molded article is produced by molding the same.

  • Patent number: 6912463
    Abstract: In a GPS navigation apparatus, a procedure of preparation of route for navigation using a specific point (WAY-POINT or MARK-POINT) established and registered by the tracking function is simplified. A TRACK list picture is read out from a MENU picture by the predetermined operation, and a desired TRACK name is designated from the list. When a type the specific point is selected by the predetermined operation to designate conversion from the TRACK to a ROUTE, position data of the START POINT, the specific point of the selected type, and the DESTINATION POINT, of the designated TRACK name are extracted, and interpolation data connecting the positions by straight line in the time series sequence is produced to construct a ROUTE for navigation. Conventionally, the selection has been made by each POINT unit, however, an automatic conversion in a batch in a TRACK unit is employed, and thus a route creating operation is extremely simplified.
