Abstract: An object of the present disclosure is to provide a doping method in which the status of the progress of a main reaction can be estimated in the lithium carbonate decomposition-type doping step of a nonaqueous lithium power storage element. The separation method, the doping method, and the doping apparatus according to the present disclosure include calculating a capacitor current density iC and an electrode reaction current density iR based on voltage and current of a cell that are measured during doping of the cell.

Abstract: The invention provides antistatic clothing suitable for wear in a room which is kept clean. The clothing, such as working clothes, work shoes, etc., manufactured from a cloth having parallel electroconductive fibers woven therein, features the incorporation of an electroconductive material at overlapped or butt-joined seams between the pieces of cloth forming the clothing to ensure a perfect electrostatic connection of all the pieces of the clothing to minimize static charging on both the clothing and the wearer's body while preventing dust from gathering on the clothing to avoid dust from becoming a cause of problems such as electrostatic breakdown of circuit elements in a semiconductor integrated circuit production plant.

Abstract: Conductive leg covers for covering the legs of a wearer of antistatic or conductive shoes are connected to the shoes. Thereby footwear is obtained which leaks static electricity safely from a wearer charged therewith, prevents the falling of dust from the cuffs of the trousers worn by the wearer, reduces wearing problems, and is easy to wear.
