Patent number: 7772769Abstract: A chip-type light-emitting semiconductor device includes: a substrate 4; a blue LED 1 mounted on the substrate 4; and a luminescent layer 3 made of a mixture of yellow/yellowish phosphor particles 2 and a base material 13 (translucent resin). The yellow/yellowish phosphor particles 2 is a silicate phosphor which absorbs blue light emitted by the blue LED 1 to emit a fluorescence having a main emission peak in the wavelength range from 550 nm to 600 nm, inclusive, and which contains, as a main component, a compound expressed by the chemical formula: (Sr1-a1-b1-xBaa1Cab1Eux)2SiO4 (0?a1?0.3, 0?b1?0.8 and 0<x<1). The silicate phosphor particles disperse substantially evenly in the resin easily. As a result, excellent white light is obtained.Type: GrantFiled: October 19, 2007Date of Patent: August 10, 2010Assignee: Panasonic CorporationInventors: Toshihide Maeda, Shozo Oshio, Katsuaki Iwama, Hiromi Kitahara, Tadaaki Ikeda, Hidenori Kamei, Yasuyuki Hanada, Kei Sakanoue

Publication number: 20090028617Abstract: There is provided a fixing apparatus capable of reducing the warm-up time, improving the heating efficiency, and suppressing the temperature increase out of the sheet width by using a magnetic adjuster. In this apparatus, the Currie temperature Tc of the magnetic adjuster material heated by electromagnetic induction is set to 220 degrees C. or below and the fixation setting temperature of a heating member corresponding to the portion where a recording material passes during continuous sheet feed is set lower than a value than the temperature at which the relative magnetic permeability of the magnetic adjuster material begins to decrease. Thus, it is possible to obtain a large difference between the heating portion and the non-heating portion, to surely prevent excessive temperature increase of the portion out of the recording material width, to reduce the warm-up time, and improve the heating efficiency.Type: ApplicationFiled: March 13, 2006Publication date: January 29, 2009Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Noboru Katakabe, Naoto Matsuo, Satoru Miyanishi, Yasuyuki Hanada, Masaru Imai, Hideki Tatematsu, Shigemitsu Tani
