A mold and molding machine having a sensor and a control circuit for monitoring operation of the molding machine during a molding operation. In one example, a display of a well log showing logged information and well depths corresponding to the information is presented. At least one of a plurality of ridges 35, 36 of the prism body 31 is formed into an R-plane. In the discharge suspend period, a voltage is applied between the scanning electrode and the sustaining electrode so that a wall voltage may be generated at which the polarity at the scanning electrode with respect to the sustaining electrode is the same as that of the initializing pulse applied to the scanning electrode in the initialization period. More specifically, a base station determines whether a periodic enhanced broadcast page is enabled or disabled, and then transmits at least one broadcast message via a first slot of a broadcast paging cycle of the F-CCCH if determined that the periodic enhanced broadcast page is enabled. A foot platform is preferably provided to support a person’s feet, and handlebars are preferably provided to support a person’s hands.
