Title: Arsenic insolubilizing treatment agent for arsenic contaminant and its preparation process
Inventor: OYO TORU
IPC: C09K3/00
Filed: 2000-01-21
Abstract: PROBLEM TO BE SOLVED: To provide an arsenic insolubilizing treatment agent with which insolubilized arsenic is not dissolved even when the pH varies because of an irreversible reaction between a hydrated oxide of a rare earth metal and arsenic, and a low-cost insolubilization process is enabled. SOLUTION: An arsenic insolubilizing treatment agent having an oxide of a rare earth metal such as cerium, lanthanum or the like as its main component is obtained by dissolving a polisher waste containing an oxide of a rare earth metal such as cerium, lanthanum and the like with an acid and then turning it into a hydrated oxide with an alkaline. This treatment agent can effectively insolubilize soluble arsenic contained in a soil, a gypsum board, or various wastes in a wide range of pH. This property effectively prevents resolubilization of the insolubilized arsenic by a subsequent change such as a pH decrease.

Title: Cylindrical lithium secondary battery
Inventor: KOISHIKAWA YOSHIMASA
IPC: H01M10/0525
Filed: 2000-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a cylindrical lithium secondary battery of a high power output density which is superior in input and output characteristics. SOLUTION: Winding group W that has an opposing length A of 3420 mm between a positive electrode and negative electrode is fabricated, and a cylindrical lithium secondary battery 20 is assembled. The diameter of the winding group is 38 mm (the value of opposing length A between electrodes/group diameter B of electrode groups W) is 90. If this value becomes smaller than 90, the current density per unit area is elevated, and because facing area of electrode becomes small, current density per area rises, and battery resistance increases, and if this value becomes greater than 110, the load charge one of the active substance becomes greater because the amount of active substance per unit area decreases, and this results in the reduction of output.
