| 20090003902 | IMAGE HEATING APPARATUS AND PRESSURE ROLLER USED FOR IMAGE HEATING APPARATUS - A pressure roller forming a nip portion for contacting to a heating member to pinch and convey and heat recording material includes: a core metal and an elastic layer containing filler, the elastic layer containing the filler including thermal conductive filler with length of not less than 0.05 mm and not more than 1 mm and with thermal conductivity λ | 01-01-2009 |
| 20090116886 | IMAGE HEATING APPARATUS AND PRESSURE ROLLER THEREIN - A pressure member contacts with a heating member | 05-07-2009 |
| 20110062140 | HEATER AND IMAGE HEATING APPARATUS INCLUDING THE SAME - To provide a heater that can reduce fixing failure in a paper passing area while suppressing a temperature rise in a sheet non-passing area, and a fixing apparatus including the heater. | 03-17-2011 |
| 20110091252 | PRESSING MEMBER AND IMAGE HEATING MEMBER USING THE PRESSING MEMBER - A pressing member for creating a nip in which the pressing member contacts a heating member and a recording material is heated while being nip-conveyed, includes an elastic layer and a high thermal conductive elastic layer which is provided on the elastic layer and has a thermal conductivity which is higher than that of the elastic layer. In the high thermal conductive elastic layer, a needle-like thermal conductivity-anisotropic filler and carbon nanofibers are dispersed in a heat-resistant elastic material. | 04-21-2011 |

| 20100103801 | OBJECTIVE LENS, OPTICAL PICKUP APPARATUS USING THE SAME, OPTICAL RECORDING/REPRODUCTION APPARATUS USING THE SAME, AND METHOD OF CORRECTING ABERRATION USING THE SAME - Provided is an objective lens for which expressions 0.83<(p | 04-29-2010 |
| 20100113859 | METHOD OF ASBESTOS DETOXIFICATION AND AQUEOUS SOLUTION FOR ASBESTOS DETOXIFICATION - A method of asbestos detoxification in which an asbestos-containing waste material in any form is made harmless while preventing asbestos particles or dust from flying or scattering. The asbestos content can be easily reduced in a short time to 0.1 wt. % or lower, which is prescribed by the Ministry of Health, Labor, and Welfare. The waste can be perfectly made harmless. Also provided is an aqueous solution for asbestos detoxification which is for use in the method. The method of asbestos detoxification comprises: bringing an asbestos-containing waste material into contact with an aqueous treating solution containing at least one fluoride ion source selected from the group consisting of the fluorides of alkali metals, alkaline earth metals, and ammonia and hydrofluoric acid and further containing at least one mineral acid selected from the group consisting of hydrochloric acid, sulfuric acid, and nitric acid so that the aqueous treating solution has a pH of 1 or lower; and allowing the resultant mixture to stand or stirring it while adding the mineral acid so as to keep the pH of the aqueous treating solution at 1 or lower. Thus, the asbestos in the asbestos-containing waste material is made harmless. | 05-06-2010 |
| 20100130806 | Method of treating asbestos-containing waste material - A method of asbestos treatment in which an asbestos-containing waste material of arbitrary configuration can be detoxified completely and safely. The method of asbestos treatment comprises impregnating an asbestos-containing waste material with an acid so as to cause at least the asbestos at the surface of the waste material to be nonasbestous and further treating the treatment product in a cement production plant. In particular, the treatment in a cement production plant is a fusion treatment by means of a cement kiln. Therefore, not only can the asbestos-containing waste material be detoxified completely and safely but also a cement reusing the waste material can be produced. | 05-27-2010 |
