摘要： A device is disclosed for removing foreign matter adhering to a probe tip face of a probe tip. The device comprises a substrate which is provided with an abrasive member (303) positioned on a base member (301), wherein these two members are connected by a metallic member (302) in between. The abrasive member (303) provides an abrasive surface adapted for removal of foreign matter from a probe tip face (300a). The base member (301) has elastic physical properties adapted to be deformed such that a portion of the probe tip (300) may penetrate into the cover.

摘要： A pressure contact type rectifier in which solder imposing a heavy environmental load is not used, and a rectifying device is protected against burning or breakage even if the temperature of the rectifying device during flowing of electric current increases or a force acting outward is applied to a lead terminal. An electrically conductive friction reducing part is provided on at least one electrode surface of the rectifying device. The friction reducing part is composed of fine conductive particles. Furthermore, contact area of the rectifying device can be kept constant by providing an expanding/contracting part on the outside of a cap of the lead terminal and securing it to the cap.
