摘要： PURPOSE:To always measure a phase difference accurately by providing a priority decision means for determining the sequence of generating two pulses before a means of detecting a time difference. CONSTITUTION:Phases of two data signals (a) and (b) to be measured are inputted into input terminals 21 and 22 respectively. Pattern match circuits 28 and 30 check for the pattern match between parallel outputs of shift registers 27 and 29 and a special bit pattern predetermined. When they coincide in the pattern, the circuits output a pattern detection pulses (c) and (d) separately. Flip flop circuits 34 and 35 transmit phase advance/lag signals (e) and (f). Four flip flop circuits 34-37 and six NAND gate circuits 38-43 are combined to output a gate opening signal (g) and a gate signal (h).

摘要： PURPOSE:To discriminate a radio channel for the signal of a maximum receiving field intensity, by selecting this signal on the basis of the preamble signal detected first in plural space diversity receiving signal demodulating circuits. CONSTITUTION:Radio waves from a moving material 1 are received by n-number receiving devices 2-1-2-n and are demodulated by respective signal demodulating circuits 3-1-3-n. A preamble signal is detected from demodulated receiving data and is transferred to a timer 5 and a data signal transmitting circuit 7. Simultaneously, receiving data with receiving field information added are applied to receiving registers 4-1-4-n. Receiving field information of registers 4-1-4-n are compared in a level comparing circuit 6 by the time-up signal of the timer 5, and a select signal is transferred to the register showing a maximum receiving field intensity. The output of this register is sent from the data transmitting circuit 7 to a data processing device. Thus, the call to the moving material is ensured even if delay times of transmission lines W1-Wn are different from one another.

摘要： PURPOSE:To realize a small sized antenna with self-resonance and excellent gain directivity performance by forming a coil whose size is sufficiently smaller than the wavelength as a loop and unfolding a conductor plate to the inside of the coil with an insulation film inbetween. CONSTITUTION:A coil 1 having a pitch (p), a width (w) and a height (h) sufficiently smaller than the wavelength is formed as a loop, feeding points 4, 4' are provided to both ends of the coil 1 and a conductor plate 3 is adhered to the inside of the loop with an insulation film 2 inbetween. Through the constitution above, as shown in figure, the coil 1 (width w=20mm, height h=2mm, pitch p=3mm, diameter d=nearly 5cm and total length = nearly 15cm) is in selfresonance near 280MHz and acts like an antenna whose band width is 5-6 MHz. Even when the dielectric substance is inserted in the loop, the change in the resonance frequency is not almost caused. Thus, even when the antenna is in use while being wound on an arm of a human body or the like, no gain decrease is caused and the excellent efficiency and directivity characteristic performance is attained.

摘要： PURPOSE:To prevent undesired location registration of a radio telephone set by allowing a radio line controller to generate a notice instruction signal in a timing different from that of a routine notice instruction signal when the radio connector is busy. CONSTITUTION:In sending a notice instruction signal to radio connection devices 81-83, a radio line controller 1 checks whether or not a radio connection device is busy and when the radio connection devices 81, 82, for example, are not busy, the notice instruction signal is sent to the radio connection devices 81, 82. If the radio connection device 83 is busy, the radio connection device 83 is stored in the storage section 7. When the communication of the radio connection device 83 is terminated, the radio line controller 1 sends a notice instruction signal to the radio connection device 83. Thus, even when the notice instruction signal is sent when the radio connection device is busy for communication, undesired location registration of the radio telephone set is not executed.
