Patent number: 8283845Abstract: In a plane emission device comprising a transparent substrate, a light scattering layer formed on a surface of the transparent substrate, and a luminescent body of organic or inorganic material which is formed on a surface of the light scattering layer and emits light by light or electric energy, efficiency to takeout light to outside is improved. The light scattering layer contains binder and two kinds of fillers, and when a refraction index of the binder is assumed as Nb, a refraction index of one of the two kinds of fillers is assumed as Nf1, and a refraction index of the other is assumed as Nf2, a relationship that Nf2>Nb>Nf1 is satisfied. Since the light scattering layer contains two kinds of fillers, disorder occurs in critical angle when light exits from the light scattering layer to the transparent substrate, incidence rate of light into the transparent substrate rises, and efficiency to takeout the light to outside increases.Type: GrantFiled: March 31, 2008Date of Patent: October 9, 2012Assignee: Panasonic CorporationInventors: Norihiro Itou, Takeyuki Yamaki, Nobuhiro Ide, Kenji Kawano

Publication number: 20100060142Abstract: In a plane emission device comprising a transparent substrate (1), a light scattering layer (2) formed on a surface of the transparent substrate (1), and a luminescent body (3) of organic or inorganic which is formed on a surface of the light scattering layer and emits light by light or electric energy, efficiency to takeout light to outside is improved. The light scattering layer (2) contains binder (4) and two kinds of fillers (5, 6), and when a refraction index of the binder (4) is assumed as Nb, a refraction index of one of the two kinds of fillers (5, 6) is assumed as Nf1, and a refraction index of the other is assumed as Nf2, a relationship that Nf2>Nb>Nf1 is satisfied. Since the light scattering layer (2) contains two kinds of fillers (5, 6), disorder occurs in critical angle when light exits from the light scattering layer (2) to the transparent substrate (1), incidence rate of light into the transparent substrate (1) rises, and efficiency to takeout the light to outside increases.Type: ApplicationFiled: March 31, 2008Publication date: March 11, 2010Applicant: PANASONIC ELECTRIC WORKS CO., LTD.Inventors: Norihiro Itou, Takeyuki Yamaki, Nobuhiro Ide, Kenji Kawano

Patent number: 7582351Abstract: There is provided a composite thin film-holding substrate in which a composite thin film (4) comprising a filler (2) having a refractive index lower than that of a substrate (1) and a binder (3) having a refractive index higher than that of the filler (2) is formed on a surface of the substrate (1). Light is efficiently scattered when passing through the composite thin film (3) which comprises the filler (2) and the binder (3) having different refractive indexes from each other. In addition, the refractive index of a composite thin film (4) comprising a filler (2) having a low refractive index is low. As a result, the discharge efficiency of light which passes through the composite thin film (4) from the substrate (1) to the external is improved.Type: GrantFiled: October 24, 2002Date of Patent: September 1, 2009Assignee: Panasonic Electric Works Co., Ltd.Inventors: Hiroshi Yokogawa, Masaru Yokoyama, Kenji Kawano, Norihiro Itou, Koichi Takahama, Takeyuki Yamaki, Akira Tsujimoto, Yasuhisa Kishigami, Nobuhiro Ide

Patent number: 6470702Abstract: An absorption water heater/chiller using lithium bromide as an absorbent and water as a refrigerant, and a high temperature regenerator therefor. The high temperature regenerator is provided with a combustion chamber defined by an inner tube (2) on the side of a blowout port of a burner (4B), from which a combustion gas is blown out. A solution is received in a liquid chamber, which extends on upper and lower sides of the combustion chamber and is defined by an outer tube (1). A refrigerant steam outflow passage (8) is formed in an upper portion of the outer tube, and gas discharge passages (13, 14) are formed at an end portion of the combustion chamber opposed to the burner. A plurality of solution tubes (3) providing communication between the liquid chamber portions on the upper and lower sides of the combustion chamber extend through the combustion chamber.Type: GrantFiled: March 23, 2001Date of Patent: October 29, 2002Assignee: Hitachi, Ltd.Inventors: Yasushi Funaba, Norihiro Itou, Tomihisa Oouchi, Satoshi Miyake, Michiyuki Uchimura
