摘要： A ceramic composition for use in production of non-linear resistors. This composition comprises strontium titanate (or a mixture containing strontium titanate as a major ingredient) and 0.1 to 1.0 mol % of Er.sub.2 O.sub.3, Ho.sub.2 O.sub.3 or mixtures thereof. In a preferred composition 0.02 to 0.2 mol % of at least one of MnO.sub.2, Co.sub.2 O.sub.3 or mixtures thereof are included. Non-linear resistors produced using the composition are comparable to those produced from conventional ceramic compositions in the threshold level voltage and non-linear factor but have greatly improved flexural strength.

摘要： A radio base station eNB10-1 sends a Resource Status Request message for requesting initiation of transmission of a second load information to a radio base station eNB10-2 when a load level thereof is equal to or higher than a first threshold, and omits transmission of the Resource Status Request message for requesting initiation of transmission of the second load information when the load level thereof is lower than the first threshold. The radio base station eNB10-2 sends a Resource Status Update message including the second load information upon receipt of the Resource Status Request message for requesting initiation of transmission of the second load information.
