  • Patent number: 8142054
    Abstract: Provided herein is a light-emitting apparatus capable of achieving both improved durability and higher brightness with an inexpensive and simple construction. A heat resistant glass substrate 51 is mounted in a vacuum chamber 5, and while an anode electrode 8 (and a light emitter 20) is mounted on the glass substrate, the glass substrate 51 is separated from a glass substrate 11. This precisely protects the vacuum chamber 5 from thermal damage due to light emission upon excitation, even when the current density between the cathode electrode 6 and the anode electrode 8 is controlled at a high level to cause the light emitter 20 to emit light at high brightness.

  • Patent number: 7960907
    Abstract: Provided herein is a light-emitting apparatus which is capable of causing the light emitted at the entire face of a fluorescent material to be exteriorly emitted with no interference and with enhanced light emission efficiency, thereby attaining an exteriorly radiated high brightness light. A cathode electrode 10 is mounted on a periphery of a transmission member 30, the anode electrode 15 is also mounted on a domain opposite to a light transmission member 30, and the surface 16a of the fluorescent material 16 to be mounted on a top layer of the anode electrode 15 is formed with a concave face.

  • Publication number: 20100129263
    Abstract: When it is determined that a driver is extremely-concentrating, a fragrance emitted by a relaxing air freshener is intermittently released by emitting. To quickly reduce the tension of the driver, a long fragrance emit period is set, while a short fragrance emit stopped period is set. When it is determined that the driver is randomly scanning, the amount of the relaxing air freshener discharged is smaller than that when the driver is extremely-concentrating, and a shorter fragrance emit period is set, while a longer fragrance emit stopped period is set. As a result, an aroma that is so faint that the driver may not notice is used to maintain the random scanning state, and further, a fragrance emitted by an awakening air freshener is emitted, as needed, near the nose of the driver.

  • Publication number: 20090009056
    Abstract: A light emitting apparatus capable of efficiently generating high luminance white light is provided. The present invention permits white light to be generated, without using low-emission efficiency white light emitters, by forming a light emitter layer 16 using a high-light emission efficiency blue light emitter and yellow light emitter. In this case, having at least a part of the blue light emitter particles 17 and at least a part of the yellow light emitter particles 18 exposed at a surface of the light emitter layer 16, respectively, allows both of such particles to be directly bombarded with electrons, thereby effecting a highly efficient electron excitation.

  • Publication number: 20040063123
    Abstract: A method is provided, which comprises examining the regulating activity of a defensin gene promoter closely associated with the expression activity of defensin, an antibacterial peptide, on the basis of the detection of a gene mutation, and estimating future susceptibility to periodontal disease. The sequence homology between DNA derived from a defensin gene promoter existing in a sample obtained from the gingival tissues of a subject and a nucleotide sequence comprising a mutation site in the promoter region, and/or compatibility in PCR amplification, are determined. Thereby a gene mutation is detected and then the site of the gene mutation is determined, so that data for the estimation can be collected.
