Title:
抵抗体の製造方法
Document Type and Number:
Japanese Patent JP4139126
Kind Code:
B2
Abstract:
A resistor (1) is produced so that dispersity of carbon black in the resistor is low in a surface of the resistor and high in an inner part thereof. In the surface of the resistor, current paths are formed by the carbon black with poor dispersity to minimize a contact resistance of a sliding contact (5) or the like. In the inner part of the resistor, the carbon black is uniformly dispersed to increase a resistance. Accordingly, a total resistance value can be prevented from lowering.
