| 20110206556 | METHOD OF DETECTING RESIDUAL DETERGENT AND DEVICE FOR DETECTING RESIDUAL DETERGENT - It is intended to provide a method whereby residual detergent (surfactant) can be conveniently and accurately detected in the step of washing or rinsing dishes or clothes, and a test device usable in examining the rinsed conditions. Namely, a method characterized by comprising bringing a test substance with a composition (test agent) comprising an oxalic acid ester, a fluorescent substance, hydrogen peroxide and a strong acid and thus easily detecting the residual detergent sticking to the surface of the test subject from the chemiluminescence thus caused; and a test device which is most suitable for storing the test agent as described above. | 08-25-2011 |
| 20100047005 | LIGHT-EMITTING WRITING INSTRUMENT AND LIGHT-EMITTING INDICATOR USING THE SAME - An object of the present invention is to provide a light-emitting writing instrument that can indicate characters and figures by utilizing chemiluminescence phenomena and a light-emitting indicator using the light-emitting writing instrument. A light-emitting wiring instrument | 02-25-2010 |
| 20100000556 | GLOWING ARTIFICIAL NAIL - The currently available artificial nails swell as a whole and undergo deformation, which damages the commercial value thereof. Moreover, they suffer from another problem of not evenly glowing as a whole due to the occurrence of some non-glowing spaces. In an airtight hollow container having a roughly crescent-shaped cross section and having light-permeability and flexibility, therefore, a space free from capillary action is ensured at the inside of an area joining the lower wall and the upper wall. Then, one of two kinds of compositions, which show chemical luminescence when mixed together, is packed in a breakable glass ampule in the airtight hollow container while the other composition is packed outside the glass ampule in the airtight hollow container. | 01-07-2010 |
| 20090325308 | METHOD OF DETECTING RESIDUAL DETERGENT AND DEVICE FOR DETECTING RESIDUAL DETERGENT - It is intended to provide a method whereby residual detergent (surfactant) can be conveniently and accurately detected in the step of washing or rinsing dishes or clothes, and a test device usable in examining the rinsed conditions. Namely, a method characterized by comprising bringing a test substance with a composition (test agent) comprising an oxalic acid ester, a fluorescent substance, hydrogen peroxide and a strong acid and thus easily detecting the residual detergent sticking to the surface of the test subject from the chemiluminescence thus caused; and a test device which is most suitable for storing the test agent as described above. | 12-31-2009 |
| 20090062033 | LIGHT EMITTING GOLF BALL - A light-emitting golf ball is provided. The light-emitting golf ball is characterized in that hemispherical first hollow portions extend from the surface toward the center of a core, second hollow portions having a diameter less than that of the first hollow portions extend from bottom zones of the first hollow portions toward the center of the core, narrow holes extend through the core from the second hollow portions to portions of the core that are opposed to the second hollow portions, a ball body includes a transparent cover layer extending over the core surface, chemical light-emitting bodies include sealed vessels made of a flexible transparent material, the sealed vessels have cylindrical portions and round light-emitting portions having a diameter greater than that of the cylindrical portions, the cylindrical portions are tightly fit in the second hollow portions, and the light-emitting portions are fit in the first hollow portions. The light-emitting golf ball has a brightness greater than that of conventional light-emitting golf balls and therefore can be visually identified from a distance. The light-emitting golf ball can be used many times by replacing the chemical light-emitting bodies with other ones. The balance of the ball is well maintained and therefore the flying performance thereof is not deteriorated. | 03-05-2009 |
| 20080246009 | Chemiluminescent Compositions - A composition exhibiting significantly increased luminance as compared with that of a known luminescent composition is provided. The composition constitutes a system in which chemiluminescence is effected by mixing two types of compositions and includes a composition A in which an oxalic ester is present in a solid state in a solution containing the oxalic ester and a luminescent substance both dissolved therein and a composition B in which aqueous hydrogen peroxide and a catalyst is dissolved in a solution. | 10-09-2008 |
