Publication number: 20160102819Abstract: A light source device which includes a light source which emits excitation light and a fluorescent layer which emits fluorescent light by the excitation light from the light source, mixes the fluorescent light emitted from the phosphor layer with the excitation light diffused and reflected in the phosphor layer, and emits illumination light. The phosphor layer includes a plurality of phosphor particles which emit the fluorescent light by the excitation light and a plurality of diffusion reflection particles which diffuse and reflect the excitation light. The plurality of phosphor particles and the plurality of diffusion reflection particles are dispersed in the phosphor layer. It is possible to reduce a regular reflection amount and adjust a color mixing ratio between the fluorescent light emitted from the phosphor layer and the excitation light diffused and reflected therein according to a mixed amount of the diffusion reflection particles 7.Type: ApplicationFiled: April 24, 2013Publication date: April 14, 2016Applicant: HITACHI MAXELL, LTD.Inventors: Tomonari MISAWA, Kousaku MORITA

Patent number: 5503787Abstract: According to this method for manufacturing a multilayer glass-ceramic circuit board, a green sheet laminate is fired in a non-oxidizing atmosphere in a first firing step so that a void content of at least 10% is maintained and strength of the ceramic laminate is increased. Then the laminate is fired in an oxidizing atmosphere in a second firing step so that the organic binder contained in the laminate is removed and the residual carbon content is at most 200 ppm. Thereafter the laminate is fired in a reducing atmosphere in a third firing step to reduce the oxidized conductor circuit. Finally, the laminate is fired in a non-oxidizing atmosphere in a fourth firing step to densify the ceramic laminate. The firing temperature in the first, second and third steps is 100.degree.-200.degree. C. lower than the softening point of the glass and the firing temperature in the fourth step is higher than the softening point of the glass and lower than the melting point of the conductor.Type: GrantFiled: March 9, 1994Date of Patent: April 2, 1996Assignee: Hitachi, Ltd.Inventors: Hirayoshi Tanei, Shoichi Iwanaga, Shousaku Ishihara, Kousaku Morita
