摘要： A radio channel estimation method includes a combination of BER (bit error rate) estimation and RSSI (received signal strength indicator) estimation. The RSSI and the BER are detected from a received signal through a radio channel, and then the radio channel is estimated based on the RSSI and the BER. A quality of the radio channel is estimated to be degraded unless the BER meets a first criterion and the RSSI meets a second criterion. The BER meets the first criterion when an average number of times during a time period that the BER exceeds a maximum value is smaller than a first threshold value. The RSSI meets the second criterion when an average number of times during a time period that the RSSI is below a minimum value is smaller than a second threshold value.

摘要： A data transmitter-receiver for reducing high-frequency noise which leads to a cause of performance deterioration of a radio instrument, and for eliminating dissipation current. The data transmitter-receiver transmits transmitting data to a modulator-demodulator connected to a radio instrument, and receives receiving data from the modulator-demodulator. A terminal controlling section 3 of the data transmitter-receiver performs data processing on the receiving data, thus outputting to a data-terminal, and performs data processing transmitting signal from the data-terminal, thus generating the receiving data. The terminal controlling section causes the low-speed clock LC to generate on the clock generating section during transmission-reception-period both of the receiving data and the transmitting data, and causes the high-speed clock HC to generate on the clock generating section during non-transmission-reception-period both of the receiving data and the transmitting data, both the high-speed clock and the low-speed clock are operating-clock. Furthermore, the operating ratio detector causes the low-speed clock to generate when the operating ratio of the terminal controlling section is low.

摘要： An RSSI detector 2 detects the electric field level of a received signal, and a transmission rate determiner 5 determines an initial transmission rate value from the detected electric field level. A radio unit 1 transmits the determined initial value to a base station 20. In response thereto, the base station 20 transmits a control signal at the assigned initial transmission rate value. A bit error rate value detector 4 detects a bit error rate of the control signal, and a transmission rate determiner 5 finely regulates the initial value according to the detected bit error rate. An optimal transmission rate is thus determined.

摘要： Dust that is accumulated in an exhaust passage provided in a chamber, the exhaust passage for discharging gas in the chamber of a semiconductor crystal manufacturing device, is removed by being sucked from the outside of the chamber. Moreover, an opening and closing valve for cleaning that is detachably attached to an opening of the exhaust passage, the opening facing the chamber, is opened and closed intermittently in a suction state. Furthermore, the opening and closing valve for cleaning is driven by a valve driving unit. The dust accumulated in the exhaust passage is removed efficiently, whereby the time required to clean the exhaust passage is shortened and fluctuations of the pressure inside the chamber when a semiconductor crystal is manufactured are suppressed.
