通常認められる現象である。When a part of the human body comes into contact with a metal object such as a car, electric refrigerator, door handle, etc., the static electricity that was being repaired flows between the metal object and the human body, causing an electric shock. This is a commonly recognized phenomenon.
このような静電気による電気的ショックを防止するため

電が発生するのを防止することができる。For example, as shown in Japanese Unexamined Patent Publication No. 59-161000, a two-wheel mold key is known in which a conductive resin is molded onto a metal key body and then an insulating resin is further molded. In this double mold key, conductive resin is first molded onto a metal key body. This conductive resin is made of polypropylene mixed with 3 to 12% by weight of carbon. The key body is further molded with an insulating resin made of ABS resin. In this way, by double-molding the conductive resin and the irresistible resin on the key body, a current flows through the conductive resin and the key body to neutralize the electric charge on the human body, reducing the m In addition to reducing the impact feeling, it is possible to lengthen the creeping surface j111 between the human body and the key body when the key touches the ground, thereby preventing direct air discharge from occurring between the two.

The reaction is carried out for about 2 hours to deposit nickel on the surface of the fibers. By heating the fiber material in a bath containing copper sulfate, sulfuric acid, metallic copper, or hydroxylamine, the -valent copper ions are uniformly deposited on the fiber material. Next, the fiber material on which copper ions have been adsorbed can be treated with a reducing aqueous solution such as hydrosulfide to precipitate copper on the surface of the fiber material.
