摘要： PURPOSE: To efficiently mount a loop antenna and a radio communication equipment circuit on a round enclosure. CONSTITUTION: Two conductor plates 22 which are round and have the diameters sufficiently shorter than the wavelength to be used are so arranged that their planes face each other, and a feed end 23 is set at a point on the outer periphery of two conductor plates, and a short-circuit conductor 24 which is sufficiently shorter than the length of the periphery and shows a sufficiently low reactance for the wavelength to be used is connected to a position most distant from the feed end. Since at least one of conductor plates is cut away with the edge part left, a display end and/or an operation end is easily installed. The radio communication equipment circuit can be mounted in the antenna structure without degrading the antenna gain, and it is miniaturized.

摘要： PURPOSE:To obtain high sensitivity both in open space and a state carried by a human body by integrating an antenna effective when carried by a human body and an antenna having an excellent characteristic in open space into one radio equipment. CONSTITUTION:A helical antenna 1 is fitted so as to be wound onto a belt 5 at both sides of a radio equipment 4 and one terminal of the helical antenna 1 is connected to a feeder. Moreover, a conductor (loop antenna element) 2 of a straight line shape is fitted to the belt 5 and both ends not connected to a feeding point 3 of the lead 2 are connected to the human body to an arm, for example. When a portable radio equipment 4 used while carried by and connected to the human body to an arm, for example, is removed from the arm (human body), a helical or zigzag antenna 1 works and a high gain is realized. When the equipment is connected to the human body, to the arm, for example, the resonance frequency of the helical or zigzag antenna 1 is transited, a loop antenna 2 works and remarkable deterioration in the gain is not caused. Thus, high sensitivity is obtained both in the state connected to the human body and in the state removed from the human body.

摘要： PROBLEM TO BE SOLVED: To immediately send back a reply message to an information communication terminal including a radio calling device, a telephone set, etc., of the caller when a portable automatic answering telephone system has a portable telephone transmitting/receiving part which performs the two-way communication with a base station by radio and a radio calling part which is dedicated to receives a radio call signal. SOLUTION: When a call signal including the information showing a caller is received at a radio calling part 106, this calling message is shown at a display part 305. At the same time, plural reply messages stored previously in a storage circuit 303 are shown at the part 305. When the optimum one of reply messages is selected, a portable telephone transmitting/receiving part 210 sends the selected message to the selection/call signal or the telephone signal of the opposite party side which is registered in a storage circuit 302 in response to the caller information.

摘要： PROBLEM TO BE SOLVED: To prevent degradation in reception sensitivity by eliminating noises produced during transmitting operation by stopping the operation of radio transmitters provided inside the same casing at the intermittent reception timing of a radio call reception part concerning a cellular mobile communication system or a packet communication system. SOLUTION: In the case of mobile communication to which a radio call receiving function is added, intermittent reception is performed at the timing generated by an intermittent reception timing generating part 16. At such a time, a transmission control part 18 stops the transmitting operation of a transmission part 17 by turning a transmission enabling signal to an inhibited state during the intermittent reception timing. Then, when it is confirmed that a reception part 16 is located in a reception stop block, the transmitting operation is started. Thus, the transmitting operation is stopped while a call receiving function is operated, the noise produced by various clock or the like following the transmitting operation is prevented from flowing in and degradation in the reception sensitivity caused by the transmitting operation can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration in reception sensitivity by commonly utilizing a battery by means of a radio call reception part and a portable telephone part and preventing noise from coming into the radio call reception part. SOLUTION: The radio call reception equipment 5 receives a radio call signal by a radio call antenna 1, demodulates it and outputs it to a radio call control part 7 and an intermittent reception timing generating part 9 through a noise preventing photocoupler 6. The radio call control part 7 detects call information of a self station by a demodulation signal and transmits it to a user, an intermittent reception timing generating part 9 closes a switch 10 and the radio call reception equipment 5 receives a call signal by the power feeding of a capacitor 13. Simultaneously the switch 12 is opened, the charging circuit of the capacitor 13 is interrupted and noise generated in the radio call control part 7 and the portable telephone part 8 is interrupted. The switch 12 is closed at the time of no reception and the capacitor 13 is charged. In this way, the radio call reception part and the portable telephone part commonly utilize the battery 11 and noise is prevented from coming into the radio call reception part through a power source system so that reception sensitivity is not deteriorated.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration in reception sensitivity of a radio call reception section by stopping an intermittent reception operation of a portable telephone set in the case that a timing of intermittent reception by a portable telephone set transmission/reception section and that of a radio call reception section are overlapped. SOLUTION: A radio call reception section 5 receives intermittently a radio call signal exclusive for calling. An intermittent reception timing generating section 6 generates an intermittent reception timing to control the intermittent reception of the radio call reception section 5. A portable telephone transmission reception section 7 uses a radio wave to make two-way communication with a base station. An intermittent reception timing generating section 8 generates a timing signal to control the intermittent reception in the case of a standby state of the transmission reception section 7 in a radio zone area or in the case of retrieval of a base station at the outside of a radio zone area. An intermittent timing signal comparator section 9 compares the intermittent reception timing of the reception sections 5, 7 based on outputs from the generating sections 6, 8. An operation stop/restoration control section 10 stops the intermittent reception operation of the transmission reception 7 when the intermittent reception timing of the transmission reception section 7 and that of the reception section 5 are equal.
