摘要： PURPOSE:To relate the outgoing/incoming operation to the operation to pull out a telescopic antenna by using a switch provided to select the telescopic antenna and the built-in antenna in the radio communications equipment using the telescopic antenna and the built-in antenna switchingly. CONSTITUTION:A switch 4 open when a telescopic antenna 2 is extracted and closed when the telescopic antenna 2 is retracted is provided to a telescopic antenna mount section 3. When the switch 4 is closed, the telescopic antenna 2 reaches the operation enable state and when the switch 4 is open, the built-in antenna is made available for operation. The switch 4 is used and when the switch 4 is open in the on-hook state, the state of the radio communications equipment is controlled to be in hook-off state and when the switch 4 is closed in the hook-off state, the radio communications equipment is controlled that the state reaches the on-hook state. Thus, the operation of the user is much simplified and no waste is caused in the structure of the radio communications equipment.

摘要： PROBLEM TO BE SOLVED: To correct time and to provide accurate time by incorporating a receiver with a long-wave standard electronic wave in a mobile radio communication terminal and achieving the function of an electronic wave clock. SOLUTION: A long-wave standard electronic wave is received by an antenna 1 for long wave and a reception low-noise amplifier(LNA) 2 for long wave, and a reference marker in a standard signal being received by a reception pulse extraction circuit 3 is detected and is sent to a time generation circuit 4 and a time difference measurement circuit 5 as a pulse signal. On the other hand, a clock 7 being generated from an oscillator 12 by an incorporated crystal oscillator is counted by a built-in clock and is sent to the measurement circuit 5 via a time signal generation circuit 6 for measurement. The difference between time from the standard electronic wave being received and time from the built-in clock is measured and is sent to a correction signal generation circuit 7, and a correction signal corresponding to the time difference is sent to the built-in clock, thus correcting time. Accurate time is displayed on a display 11 as an electronic wave clock also at the mobile radio communication terminal by the loop control.

摘要： PROBLEM TO BE SOLVED: To attain the operation from a remote location by incorporating a radio call equipment being able to receive character information or a digital cordless receiver in an automobile, making a phone call from a remote location and sending a specific numeral string so as to start an engine starter in the automobile. SOLUTION: A PHS or an outdoor mobile communication equipment 1 or the like makes a phone call to a base station 3 or a general wired telephone set 2 makes a phone call to a specified telephone number to call a radio calling device 12 being able to receive character information. Furthermore, in order to start an engine 11 of an automobile 7, a key button of the telephone set is used to input a numeral string the same as that stored in a memory in a microcomputer 9 in the automobile 7 in advance. In the automobile 7, the numeral string received by a radio caller 8 is sent to the microcomputer 9 and the microcomputer 9 sends an engine start signal to an engine starter 10, which is started to start the engine 11.

摘要： PURPOSE:To obtain a SAW filter transducer electrode material with lower resistivity than that of aluminum by using a superconduction thin film as a transducer electrode material of the SAW filter. CONSTITUTION:The surface acoustic wave SAW filter consists of a piezoelectric substance 1-1, an interdigital transducer 1-2, a stripe 103, a lead wire 1-4 and terminals 1-5, 1-6. The stripe 103 constitutes an IDT 102 and the type of material is superconduction ceramic thin film. Thus, the electric resistance of the IDT electrode of the SAW filter is made principally zero. Then the insertion loss of the SAW filter is considerably reduced than the case with using aluminum.

摘要： PROBLEM TO BE SOLVED: To improve operability by automatically sending from an incoming responding device a message addressed to a call originating party where status has been previously stored when one cannot immediately respond to an incoming call from the other party which is sending. SOLUTION: When a user moves a portable telephone system 1 close to a place where a radio transmitter 2 exists, it automatically switches to a response mode that is suitable for the place. When there is an incoming call to the telephone 1, an answer message that is stored in the telephone 1 is automatically sent in place of the user, when he is not able to talk immediately. This enables sending a message, that is preliminarily stored to be sent for an call originating party, to the above party. As a result, the sender can recognize the status of the user of the telephone 1. Further, the sender records the message by providing a recording function with the telephone 1 side. Thus, telephone communication can be facilitated.

摘要： PURPOSE:To reduce the length of the portable telephone set and to make the size small by adopting the configuration such that a display device of a main body section comes to the front side when the telephone set is folded in the standby state and a speaker is hidden behind a part having a microphone. CONSTITUTION:A display device 3 and a speaker 4 are arranged in this order to a main body section 1 and an operation button group 5 is arranged to an open/close section 2. When the telephone set is folded into two parts, the open/close section 2 is covered up to a speaker 4 of the main body section 1. Furthermore, a battery 8 is mounted to a lower part of the main body display section 1. Since the size (length) of the telephone set depends on the length of the display device 3 and the open/close section 2 in this state and it is not required to take the length of the speaker 4 into account different from a conventional telephone set, the length is reduced by the length of the speaker 4. Furthermore, a cylindrical battery has a larger diameter, then the thickness of the telephone set is made thicker by mounting the battery to the main body section 1 to which a printed circuit board is contained, and the thickness is increased and the miniaturization is made difficult, then the thickness of the main body section 1 is made thinner than the thickness of the battery 8 by mounting the battery to the lower part (side face) of the main body section 1.
