Herein provided are the macroporous carbon material starting from a wood material, and a method for producing it. | 09-03-2009 |
20100196746 | CATALYST MATERIAL FOR PRODUCING OXYGEN GAS FROM WATER - Provided is a catalyst material comprising aggregates of nanoneedles of mainly R-type manganese dioxide and having a mesoporous structure. With this, water can be oxidatively decomposed under visible light at room temperature to produce oxygen gas, proton and electron. Also provided is a catalyst material comprising aggregates of nanoparticles of mainly hydrogenated manganese dioxide. With this, acetic acid or an inorganic substance can be synthesized from carbon dioxide gas. | 08-05-2010 |
20130064972 | METHODS FOR SYNTHESIZING NANOMETER-SIZED MANGANESE DIOXIDES HAVING RAMSDELLITE-TYPE CRYSTAL STRUCTURES AS WELL AS METHODS FOR PRODUCING HYDROXIDE ION-DERIVED PROTON, ELECTRON AND OXYGEN USING MANGANESE DIOXIDES - By means of a series of wet multistage oxidation process comprising: Step 1 for adding an alkaline reagent to an aqueous solution of a manganese compound containing a divalent manganese thereby precipitating a manganese hydroxide; Step 2 for adding an aqueous hydrogen peroxide while keeping the temperature of the water of the aqueous solution comprising the manganese hydroxide at room temperature thereby converting into a manganese oxide; and also Step 3 for adding a dilute acid to the manganese oxide in a state where the water is coexisting, a nanometer-sized manganese dioxide having a ramsdellite-type crystal structure is obtained. | 03-14-2013 |

20100022696 | Electromagnetic wave-permeable brilliant coated resin product and manufacturing method therefor - The present invention provides an electromagnetic wave-permeable brilliant coated resin product which has a brilliant coating film formed by applying a coating composition that includes a planar brightening material formed from aluminum, on a resin substrate. Within the brilliant coating film, the brightening material is oriented in a state such that a plane thereof is biased toward a direction that follows a surface of the brilliant coating film, and an average overlapping quantity (y), which is an average of a quantity of brightening material that crosses one orthogonal line that is orthogonal to the surface of the brilliant coating film, and an average inter-brightening material distance (x), which is an average of distances on the orthogonal line between adjacent brightening materials that cross said orthogonal line, satisfy the following two formulae: | 01-28-2010 |

20110287693 | NUMERICAL CONTROLLER HAVING OSCILLATING OPERATION FUNCTION CAPABLE OF CHANGING SPEED IN OPTIONAL SECTION - A machine tool has an oscillating axis that reciprocates in an optional region. A numerical controller that controls the machine tool designates positions of a lower dead point and a upper dead point when the oscillating axis of the machine tool reciprocates, and a reference speed during the oscillating operation when the oscillating axis reciprocates. The numerical controller then calculates, from the current position of the oscillating axis, a current phase in the case where one stroke of the oscillating axis is defined as one cycle, and calculates the speed of the oscillating axis at the current phase based upon the calculated current phase and the reference speed. | 11-24-2011 |
20140379115 | NUMERICAL CONTROLLER OF MACHINE TOOL FOR DRILLING - A numerical controller of a machine tool changes a feed speed of a feed shaft and a spindle rotation speed, in accordance with a current position of a rotary tool in a specified arbitrary area above and below a position where a workpiece and the rotary tool come in contact with each other. | 12-25-2014 |
