Title: Antistatic ring
Inventor: OSAWA KOICHI
IPC: H05F3/02
Filed: 1994-06-28
Abstract: PURPOSE:To prevent the accumulation of static electricity due to friction with clothes by providing metals of different ionization tendency on the inner side of an insulator ring, jointing each one end of the metals with the other end kept free, and then putting the ring on a finger. CONSTITUTION:A metal 4 of weak ionization tendency and a metal 5 of strong ionization tendency are laid on the inner side of an insulator ring 1. Also, one end of each of the metals 4 and 5 is jointed at a position 6, thereby forming the upper side 2 of the ring 1. Also, the free ends of the metals 4 and 5 are used as the lower side 3 of the ring 1. When the ring 1 so made is put on a finger, the skin of a hand wetted with sweat comes in contact with the metals 4 and 5 having different ionization tendency. As a result, electric current flows from the metal 4 to the metal 5 via the joint section 6, with the metal 5 having strong ionization tendency as a negative electrode. Also, electricity likely to be charged due to friction, instantaneously flows to the metals 4 and 5 always acting conductors, and is neutralized due to induction with electric charge moving between the metals 4 and 5 having different ionization tendency.
