Abstract: A hot-pressed member is disclosed including at least one surface that has a filtered centerline waviness Wca of less than or equal to 1.5 ?m.

Abstract: A data management system includes a client apparatus, a window server apparatus and a plurality of data server apparatuses. The client apparatus is configured to transform private information including a character string having at least one item into a character code. The client apparatus is configured to divide the character code into at least two divisional character code portions. The client apparatus is configured to transmit the divisional character code portions to the window server apparatus. The window server apparatus is configured to store first data, which is formed by a part of the divisional character code portions, in one data server apparatus of the plurality of data server apparatuses and store second data, which is formed by a part of the divisional character code portions that is different from the part forming the first data, in another data server apparatus of the plurality of data server apparatuses.

Abstract: According to the present invention, a method which dissolves hydrogen in a liquid that includes a radioactive substance is able to reduce the amount of radioactivity of the liquid. With respect to this method, the radioactive substance may include radioactive cesium, and hydrogen may be dissolved in the liquid by mixing a substance that contains a radioactive substance with a hydrogen water that contains 1.0 ppm or more of hydrogen.

Abstract: In an infrared stove apparatus, there is provided a stove body having a radiation window at the front and upper portions of the stove body. A frame is placed within the stove, and one open end of the frame faces to the front portion of the stove body so as to serve as a radiation opening, the other open end of the frame having a porous burner plate through which a mixture of fuel gas and air is to be released. An exhaust opening is provided at the upper lateral side of the frame to pass exhaust gas released through the porous burner plate when the mixture of fuel gas and air is ignited at the time of operation. A metallic net of a suitable mesh screen is provided within the exhaust opening to increase fluid-resistance of the exhaust gas flowing out through the exhaust opening so as to keep a uniform velocity distribution of the exhaust gas while restraining outside air from entering into the frame through the radiation opening leading to the exhaust opening.

Abstract: NO.sub.x gas remaining in a purified exhaust, which has been desulfurized, in accordance with a publicly known method using coke oven gas, by washing the original exhaust containing SO.sub.2 and NO.sub.x with a water solution mainly consisting of ammonium sulfite concentrated to about 30 percent by weight, the pH value and the temperature thereof being adjusted to 6.1 to 6.5 and 50.degree. to 55.degree.C respectively, can be reformed into harmless N.sub.2 by passing said desulfurized exhaust through a reducing catalyst at a temperaure of 200.degree. to 450.degree.C, wherein ammonia gas naturally brought into said desulfurized exhaust from the washing solution acts as a reducing agent.
