摘要： A PTC composition comprising at least one polymer, from 5% to 45% by volume of electrically conductive or semiconductive particles having a room temperature electric conductivity of at least 10.sup.2 [s/m] dispersed in said polymer, and from 0.2% to 20% by volume of thermally conductive particles having a room temperature electric conductivity of no more than 10.sup.-3 [s/m] and a thermal conductivity of at least 20 [w/m.multidot.k] dispersed in said polymer. A PTC device using such a PTC composition has a high ratio of peak resistance to room temperature resistance, and exhibits high safety.

摘要： A cesium beam tube for use as a frequency standard, wherein the beam path from the cesium beam source unit to the detector is hermetically sealed.This cesium beam tube includes a rigid high frequency transition part composed of a metallic block which is used as the basic support of the tube. A first state selection magnet part and the cesium beam generator are coaxially coupled to the one end of the rigid cavity, while the second state selection magnet part and detector are coaxially connected to the other end of the rigid cavity. The rigid cavity, first and second magnet poles, cesium beam generator and the detector form the vacuum envelope by themselves, and the permanent magnets and other related parts are not in a vacuum.
