    摘要： PROBLEM TO BE SOLVED: To solve the problem with a system where a slave wireless terminal performs clock setting by capturing a beacon signal from a master wireless terminal and communication is synchronously performed, wherein a clock error may become considerable, when the time for the slave wireless terminal to capture the beacon is prolonged for power reduction.SOLUTION: A wireless communication apparatus is configured to periodically transmit a beacon signal for a communication partner to synchronize transmission and reception timing, and transmit a repeat frame containing an identification code multiple times in the reception timing of the communication partner if information to be transmitted is generated, and then transmit a main frame containing a data signal. In the wireless communication apparatus, the number of times of transmitting the repeat frame can be varied in accordance with a time difference between timing in which the information to be transmitted is generated and timing to receive the beacon signal for the communication partner to perform synchronous correction.

    摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to attain both the prevention of leaving a mobile phone behind and convenience that function restriction is applied in use. SOLUTION: This radio warning device has a transmitter 2, a receiver 7, a receiving level determining means 3 for calculating a receiving level value on the basis of a plurality of pieces of receiving level information and a distance estimating means 4 for estimating the distance between the transmitter 2 and the receiver 7 on the basis of the receiving level determined by the receiving level determining means 3, wherein the transmitter 2 and the receiver 7 periodically or unperiodically transmits and receives radio to thereby confirm a distance between them, and when the distance estimated by the distance estimating means 4 is equal to or larger than the predetermined distance, functions of a main body device connected to the transmitter 2 or the receiver 7 are restricted or a warning is sent.

    摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to establish both such convenience that the mislaying of a portable telephone is prevented or functional restriction is started during its use and prolongation of a battery life. SOLUTION: Ta and an "ideal value" in the case of receiving an authentication signal (2)18 are compared. When Ta in the case of receiving the authentication signal (2)18 is defined as "1.00 m seconds+A", a difference between the "1.00 m seconds+A" and an "ideal value: 0.95 m seconds+A" is calculated as "+0.05 m seconds". Therefore, the reception timing of the next authentication signal (2)18 is obtained as the correction quantity of "+0.6 m seconds"+"+0.05 m seconds"=0.65 m seconds. Radio equipment B7 starts a timer T1' for measuring the reception timing of the next authentication signal (2)18 by taking into consideration the subtraction of 0.95 m seconds as the error of the temperature fluctuation of an internal clock.

    解决方案：在接收认证信号（2）18的情况下，Ta和“理想值”被比较。 当接收到认证信号（2）18的情况下的Ta被定义为“1.00m秒+ A”时，计算出“1.00m秒+ A”与“理想值0.95m秒+ A”之间的差 为“+ 0.05米秒”。 因此，作为“+0.6m秒”+“+ 0.05m秒”= 0.65m秒的校正量，获得下一个认证信号（2）18的接收定时。 无线电设备B7通过考虑到0.95m秒的减法作为内部时钟的温度波动的误差来启动用于测量下一个认证信号（2）18的接收定时的定时器T1'。 版权所有（C）2008，JPO＆INPIT

    摘要： PROBLEM TO BE SOLVED: To provide a radio apparatus which extends the service life of a battery of a wireless key and a cellular phone without impairing a function (security function) of preventing an electronic device such as the cellular phone from being left behind or stolen, and also to provide its program. SOLUTION: In the radio apparatus, a radio device A(2) repeatedly transmits an identification signal at a predetermined cycle T1 until receiving a response from a radio device B(7). The identification signal to be transmitted at the predetermined cycle T1 from the radio device A(2) has a preamble signal of a predetermined length, and the radio device B(7) repeats an operation of intermittently performing a reception operation at a time interval T2 shorter than the preamble signal of the predetermined length by a time period longer than the predetermined cycle T1, and then, stopping the reception operation during a predetermined time T3.
