Title:
CURRENT STABILIZING ELEMENT
Document Type and Number:
Japanese Patent JPH04146602
Kind Code:
A
Abstract:

PURPOSE: To obtain a current stabilizing element in which the width of a current stabilizing range to a voltage change and a current change rate is optimally set, by holding a plurality of barium titanate semiconductor porcelains having different Curie points by two electrode plates, connecting them in parallel, and forming one element.

CONSTITUTION: A base 1 is formed in a multiple structure in which four types of barium titanate semiconductor porcelains molded in a disclike or doughnut disclike state of different diameters and characteristics are concentrically disposed and can be brought into close contact with each other. The arraying order of the four types of the porcelains is arbitrary without depending upon the characteristics. In order to connect the four types of the porcelains in parallel, electrode plates 2, 3 are mounted on the upper surface and the bottom of the base 1. Although the four types of the porcelains are used, the number of steps of forming the electrodes is simplified similarly to one element. Further, terminals 4, 5 are attached to the plates 2, 3, and the entirety of the base 1 and the plates 2, 3 are covered with a resin coating film to obtain a radial type current stabilizing element 6.
