20130277716 | TERAHERTZ ELECTROMAGNETIC WAVE CONVERSION DEVICE - The purpose of the present invention is to improve the efficiency of conversion between terahertz electromagnetic wave energy and direct current energy via plasma waves in a terahertz electromagnetic wave conversion device with a field effect transistor structure. This invention has an HEMT structure having a substrate, an electron transit layer, an electron supply layer, a source and a drain, and includes a first and second group of gates. The gate length of each finger of the first group of gates is narrower than the gate length of each finger of the second group of gates, and each finger of each group of gates is disposed between the source and the drain on the same cycle. A first and second distance from each finger of the first group of gates to two fingers of the second group of gates adjacent to each finger are unequal lengths. | 10-24-2013 |

20130330634 | ELECTRODE UNIT - The invention relates to an electrode unit for an electrochemical device for storing electrical energy, comprising a solid electrolyte ( | 12-12-2013 |
20140027300 | PROCESS FOR PREPARING AN ALKALI METAL - Process for preparing an alkali metal from a salt of the alkali metal which is soluble in a solvent, including a first electrolysis, a concentration, and a second electrolysis. The first electrolysis produces a product mixture. This product mixture is then concentrated to give a largely solvent-free alkali metal (poly)sulfide melt. A second electrolysis at a temperature above the melting point of the alkali metal is then performed in a second electrolysis cell comprising an anode space and a cathode space, separated by a solid electrolyte which conducts alkali metal cations. The alkali metal (poly)sulfide melt from the concentration step is fed to the anode space. Sulfur is removed from the anode space and liquid alkali metal is removed from the cathode space. | 01-30-2014 |
