Abstract: Inclusion of relatively small amounts of organic ionic species, such as calcium stearate, in the preparation of an electrically conductive polymer composite composition provides a composition having enhanced electrical properties relative to the composite composition lacking the added organic ionic species. As a result of this enhancement, normally insulating materials which rely upon a conductive filler to render them electrically conductive, can be made to achieve a given level of conductivity using less of the conductive filler than would otherwise be required. As a result, the adverse effects of the conductive filler on the polymer's physical properties can be minimized while maintaining a high level of electrical conductivity.

Abstract: A ceramic bearing ball in which at least a portion of a constituent ceramic is formed of an electrically conductive inorganic compound phase, whereby a proper electrical conductivity is imparted to the ceramic. Thus, electrifying of a bearing ball is prevented or effectively suppressed. This prevents the problem involved in production of balls of small diameter wherein such balls adhere to an apparatus (e.g., a container) during production thereof, thus hindering smooth progress of the production process. In addition, when ceramic balls are used in precision electronic equipment, such as a hard disk drive of a computer, which is operated at high rotational speed, adhesion of foreign substance due to electrification of the balls, and resultant generation of abnormal noise or vibration can be prevented or effectively suppressed.

Abstract: A composition of electric beam for spark plug and cable is provided which is consisted of carbon, Magnesium Oxide (MGO), and binder with suitable percentage in weight. The electric beam can be disposed between the center electrode and, the spark plug terminal. Since the electric beam comprises Magnesium Oxide (MGO) and carbon, the carbon is an excellent conductive material while the Magnesium Oxide (MGO) is an excellent insulator. Even the Magnesium Oxide (MGO), is an insulator, it has excellent potential capacity of store and excite the electrical charge. Consequently, when the current with high voltage flows over the electric beam, an intensified and concentrated current is generated. As a result, the spark is, stronger as compared to those spark plug without the electric beam. In light of this, when a stronger spark is generated, a complete combustion can be attained, i.e.--higher output of power can be attained.
