  • Patent number: 11898079
    Abstract: A phosphor powder composed of ?-sialon phosphor particles containing Eu. The phosphor powder has an ammonium ion concentration CA of the phosphor powder of equal to or more than 15 ppm and equal to or less than 100 ppm, which is determined from the following extracted ion analysis. (Extracted Ion Analysis A) 0.5 g of a phosphor powder is added to 25 ml of distilled water in a polytetrafluoroethylene (PTFE)-made container with a lid and held at 60° C. for 24 hours, and then a total mass MA of ammonium ions included in an aqueous solution obtained by removing a solid content from the solution by filtration is determined using ion chromatography. Then, CA is determined by dividing MA by the mass of the phosphor powder.

  • Patent number: 10768193
    Abstract: A needle for forming a cut in a reagent bottle lid is shaped such that an expansion portion which pushes and opens a cut and a piercing portion which forms the cut are integrated with each other. Consequently, only a single operation for moving the needle downwardly will form a cut using the needle and expand the cut using the expansion portion. Further, the smaller diameter of the expansion portion than the diameter of a circumscribed circle of a cross section of the piercing portion but equal to or greater than the diameter of the reagent probe can form cuts uniformly.
