A system for making extruded cement-based articles. The process can include forming a cement-based feed mixture including water, aggregate and binder and directing the feed mixture to a vacuum zone, wherein sufficient vacuum is maintained in the vacuum zone to remove entrained air and, preferably, excess water, from the feed mixture. The feed mixture is held in the vacuum zone at a negative pressure for a time sufficient to form a vacuum-treated or densified mixture. The vacuum-treated or densified mixture is passed through an extruder at an elevated pressure to provide an extruded cement-based article.

A broadcast receiver includes a controller that detects a reception log of a receiving unit and that records the reception log in a reception log memory. The reception log includes at least the reception channel, reception start time, and reception end time. Periodically an audience member connects the broadcast receiver to a general-purpose computer. The general-purpose computer transmits the reception log data recorded in the reception log memory with a receiver ID written in a ROM through a telephone line over a communication network, such as the Internet. A person who computes viewing/listening information obtains the reception log data and receiver ID from the communication network and computes viewing/listening information, such as a program rating. Instead of providing the broadcast receiver with the reception log memory and a computer interface, a removable storage unit with a computer interface can also be used.
