Abstract: An electrification preventing is disclosed in which granular and/or powdered Si or SiOx (0<x<2) which is charged with negative static electricity (negatively-ionized) is sealed in a glass container. The glass container that is placed in a body adjacent an area where the desired effect is to be achieved. In one preferred embodiment of the invention, the glass container is embedded in the ground. The glass container, such as a tube, contains a negatively charged material such as Si/SiOx, the purpose of which is to interrupt stray electrical current in the body and thereby reduce positive static electricity in the environment.

Abstract: The material for inverting static electricity (or static electricity inverting material) of the present invention contains Si or SiOx (0<x<2) on the surfaces or inside of a base material. The Si or SiOx may be directly vapor-deposited on the base material. Or a silicon sheet prepared from a raw material of Si or SiOx may be attached to the base material. Furthermore, in the case where the static electricity inverting material contains the Si or SiOx thereinside, the Si or SiOx may be sandwiched or mixed in the base material. Moreover, the base material may be singly composed of the Si or SiOx. The invention provides also a method for removing static electricity by covering the surface of a static electricity producing body partly or totally with the static electricity inverting material, alternately, by covering a space accommodating a static electricity receiving body which is electrically charged through connection with the external space with the static electricity inverting material.

Abstract: A plant activator which is strip-shaped, and includes a silicon layer provided on one or both surfaces of the base sheet or within a base sheet and containing Si or SiO.sub.X (0<X <2) as a main component, wherein the silicon layer is provided by vapor-deposition or bonded by an adhesive. The plant activator is hung on or near the plants.
