Title: Multicolor image forming device
Inventor: KUSUMOTO KEIJI
IPC: H04N1/48
Filed: 1988-07-16
Abstract: PURPOSE:To prevent the omission of image information irrespective of the lightness difference of color information by converting plural color data of a read unit to single color data selected by a specific means of an erasion unit, and controlling an erasing means, based on its data. CONSTITUTION:Color data read by a color CCD 51 of a document reading means is converted to color data of an erasion unit of an erasing means 5 whose size is different from that of a read unit and stored in a memory 70, and based on its data, the means 5 is controlled. In this case, when data are all the same, the data are converted to its color, and when two colors or more are mixed, the data are converted to one color selected in accordance with the number of colors which exist and the priority determined in advance. In such a way, the omission of image information is prevented and a color copy in which the tone of a color is scarcely varied can be obtained quickly at a low manufacturing cost since a small memory capacity is enough.

IPC: H01M6/16
Filed: 1980-12-16
Abstract: PURPOSE:To reduce internal resistance for improving discharge characteristics by restricting the quantity of an electrolyte to a specific range to theoretical capacitance of a positive electrode in a battery using lithium for a negative electrode and iron sulfide for the positive electrode. CONSTITUTION:In a battery using lithium for a negative electrode 4 and using a compressed compact of a composite agent comprising iron sulfide, graphite, acetylene black and fluororesin being active materials for a positive electrode 2, an organic electrolyte is restricted in the amount to 0.7-0.9mul per theoretical electric capacitance of the positive electrode of 1mAH. The electrolyte is obtained, for example, by dissolving lithium perchlorate into a mixed solvent of propylene carbonate and 1,2-dimethoxy ethane. The positive electrode 2 is, for instance, a compact obtained by compressing with a filling factor of 30-90% a composite agent comprising a mixture of iron sulfide, graphite, acetylene black and fluororesin by wt% of 85, 8, 4, 3. The filling factor is desirable to be small. Hereby, since the quantity of the electrolyte is increased, it is possible to reduce internal resistance and to improve discharge capacity.

Title: Concentration of yttrium solution
Inventor: SAWAI KEIJIROU
IPC: C01F17/00
Filed: 1986-07-31
Abstract: PURPOSE:To enable economical concentration of an yttrium solution at reduced energy consumption, using a relatively small-sized apparatus, by adjusting the pH of the solution within a specific range and subjecting the solution to electrodialysis. CONSTITUTION:An yttrium solution is adjusted to 0.5-4pH and concentrated by electrodialysis. The adjustment of the pH within the above range is effective in preventing the precipitation during electrodialysis and the lowering of current efficiency caused by the transfer of an acid as a main reaction. Accordingly, the yttrium solution can be concentrated in high efficiency. The process is extremely economical compared with the thermal concentration process since it can be carried out using a relatively small-sized apparatus at an energy consumption of about 1/10 of the conventional process.
