Publication number: 20060006789Abstract: A fluorescent display tube is provided, which employs a non-evaporation type getter, instead of the evaporation-type Ba getter, whereby the serviceable life of the fluorescent substance containing SrTiO3 as a base component is prolonged. At least one or more elements selected from the group consisting of Zr, V, Fe, Ti, Ma, Mn, and La are used for the getter for fluorescent display tubes, each which employs a fluorescent substance containing SrTiO3 as a base component. This feature allows carbon series residual gases remaining in the tube to be removed, so that the serviceable operation can be prolonged.Type: ApplicationFiled: July 8, 2004Publication date: January 12, 2006Inventors: Shigeo Itoh, Hitoshi Toki, Hirokazu Takanashi, Hisamitsu Takahashi, Yoshitaka Sato, Kazuhiko Itakura, Takuya Hamada, Takao Shiraga, Kiyoshi Tamura, Tatsuo Yamaura

Patent number: 6660187Abstract: A phosphor for use with low speed electron beams is characterized by the following general composition formula. (Y, Ce)2O3.nSiO2 0.4≦n<1.Type: GrantFiled: June 6, 2002Date of Patent: December 9, 2003Assignees: Nichia Corporation, Futaba CorporationInventors: Yasunobu Noguchi, Kiyoshi Tamura

Patent number: 6517740Abstract: The present invention provides a phosphor of formula A2SiO5:B (A is Y or Gd, and B is Ce or Tb) which is characterized by a surface elemental composition represented by (A+B)/Si ranging from 1.5 to 2.5, wherein A is Y or Gd, and B is Ce or Tb; and method for preparing said phosphor. One embodiment of the method is as follows: a SiO2 powder is mixed with co-precipitate (Y, Ce)2O3 (Ce/Y=0.01), in an amount ranging from 10 to 110 mol % based on the amount of (Y, Ce)2O3, and the mixture is charged into the inner crucible of a double-walled aluminum crucible. After graphite is charged between the inner and outer crucible, the mixture is calcined at 1450° C. for 2 hours to obtain an Y2SiO5:Ce phosphor. The luminous efficiency of a field emission display (FED) prepared employing the Y2SiO5:Ce phosphor was measured at an anode voltage of 600V, an electric power input of 30 Wp-p and a duty rate of 1/240.Type: GrantFiled: March 26, 2001Date of Patent: February 11, 2003Assignee: Futaba Denshi Kogyo Kabushiki KaishaInventors: Fumiaki Kataoka, Kiyoshi Tamura, Yoshitaka Sato, Yuji Nomura
