    • A plurality of variables representing the characteristics of a knock is obtained from an output signal of a sensor. The variables include a peak value of the knock frequency component in the output signal of the sensor and a waveform correlation coefficient representing the correlation between the waveform of the output signal and an ideal knock waveform, which is the waveform specific to a knock. The peak value and the waveform correlation coefficient are normalized, and a detection distribution is created using the obtained normalized data values. A correlation coefficient for knock determination representing the correlation between the detection distribution and an ideal knock distribution is calculated. The correlation coefficient for knock determination is compared with a predetermined knock determination threshold value, and the knock determination threshold value is corrected in accordance with the comparison result. As a result, the accuracy and the reliability of knock determination are improved.

    • Disclosed is a transmission power control method which enables communications between a base station and a terminal station to be always performed at a high transfer rate by always assuring an uplink communication path between a base station which can transfer a downlink signal most efficiently and a terminal station. Each of terminal stations 111 to 119 selects a base station which can receive a downlink radio wave with the highest power, and transmits a code for identifying the base station on an uplink signal. When the received power of the uplink radio waves transmitted from the terminal station which has transmitted the code identifying the own station is higher than the threshold value, each of base stations 501 to 503 transmits a control signal for decreasing the power to the terminal station. When the terminal station sends a code for identifying another station or the power of the uplink radio waves received from the terminal station is lower than the threshold value, a control signal for increasing the power is sent to the terminal station. When even one power control signal for giving instruction to decrease the transmission power exists, each terminal station decreases its transmission power. When there is not the power control signal, each terminal station increases its transmission power.
    • 公开了一种发送功率控制方法,其通过始终确保可以最有效地传送下行链路信号的基站与终端站之间的上行链路通信路径,使基站和终端站之间的通信始终以高传输速率进行通信 。 终端站111至119中的每一个选择能够接收具有最高功率的下行链路无线电波的基站,并且在上行链路信号上发送用于识别基站的码。 当从发送了本台站的代码的终端发送的上行无线电波的接收功率高于阈值时,基站501〜503中的每一个向终端站发送降低功率的控制信号。 当终端发送用于识别另一站的码或从终端接收到的上行电波的功率低于阈值时,向终端发送增加电力的控制信号。 当存在用于给出降低发送功率的指令的一个功率控制信号时,每个终端站降低其发送功率。 当没有功率控制信号时,每个终端站增加其发射功率。

    • A control unit 6 causes a vertical scanning circuit 3 to cyclically select any one-dimensional pixel line from among pixel lines 21 to 23 each time a prescribed H period elapses, and controls a read circuit 5 and a horizontal scanning circuit 4 so as to read out pixel signals of an object which has been exposed by the selected pixel line. The control unit 6 further controls a vertical movement unit 8 in such a manner that the scanning speed S satisfies S=P/4H, where P is the arrangement pitch in the vertical direction of the pixel lines 21 to 23 and H is the H period.
