    摘要: A thermal recording apparatus for use in a facsimile recording apparatus or the like. Thermal resistors arranged in a thermal recording head are divided into a predetermined number of groups. By group-selection circuits which constitute constant-voltage circuits and which are provided correspondingly to the groups of thermal resistors, the thermal resistors are actuated in a time-divisional manner so as to record image information on a thermosensitive recording paper, whereby each constant voltage circuit with a relatively small capacity is actuated in a time-divisional manner for driving the recording head. Thus, a regulated power supply apparatus with a large capacity is not required, so that the power consumption of the recording apparatus can be reduced and the size thereof can be decreased.

    摘要: A process and system are disclosed for producing lithium oxide from lithium nitrate. In the process and system, the lithium nitrate is thermally decomposed in a manner such that a fraction of the lithium nitrate forms lithium oxide, and such that a remaining fraction of the lithium nitrate does not decompose to lithium oxide. The thermal decomposition may be terminated after a determined time period to ensure that there is a remaining fraction of lithium nitrate and to thereby produce a lithium oxide in lithium nitrate product. The lithium oxide in lithium nitrate product may have one or more transition-metal oxides, hydroxides, carbonates or nitrates added thereto to form a battery electrode. The lithium oxide in lithium nitrate product may alternatively be subjected to carbothermal reduction to produce lithium metal.

    摘要: The present invention provides an inexpensive process for the preparation of lithium salts of formula LiX having a desired or required level of purity using lithium chloride and lithium sulfate. In the process of the invention, a lithium salt selected from lithium chloride, lithium sulfate, and combinations thereof is reacted with NaX or KX in a aqueous, semiaqueous, or organic solution and the precipitated salts are removed to obtain the LiX solution of desired purity. Preferably, a semiaqueous solution containing water and an organic solvent is used at some point in the reaction. The process of the invention eliminates the use of highly acidic materials and thus reduces the cost of raw materials and the need for specialized equipment.
