In a mobile communications system, a mobile station communicates with a first base station operating at a first antenna specific weight factor. The method is format and bit rate transparent, and a network element does not need to read bits to interpret a signaling message. The boost means is composed of a level detector for detecting an output level of the channel signal, an operation portion for calculating and determining an amount of boost based on a result of the level detector, and a signal boost portion for boosting the channel signal based on a result of the operation portion. The tube is also laid in a meandering or zigzagging pattern between a liquid crystal panel and a housing of the display part. Preferably, the specific point belongs to the sequence dimension. Molecular sieves including zeolites, metal substituted aluminosilicates, and metallosilicates can be stabilized by this method.
