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.

摘要： PURPOSE:To make the radio telephone set main body small to the utmost by adopting the structure for a microphone support member so as to be drawn out of a main body of the radio telephone set and using the drawn-out part as an antenna. CONSTITUTION:An antenna 6 is suspended and projected from a bottom face 1a and a microphone 5 is fitted to the tip of the antenna 6. In the case of talking, a speaker 2 built in the main body 1 is in contact with an ear and the microphone 5 at the tip of the antenna 6 is placed close to a mouth. Thus, even when the size of the main body 1 is made small, a sufficient distance is ensured between the speaker 2 and the microphone 5 and talking quality is kept constant. Moreover, since the support member of the microphone 5 is used as an antenna, it is not required to provide the antenna separately from the support member of the microphone.

摘要： PURPOSE:To increase the attenuation quantity on the low frequency side of a blocking band and to enhance the sharpness of rise characteristics by electrically and serially connecting plural elastic surface wave transducers successively arranged from lower resonance frequencies in the propagating direction of the elastic surface wave of more than one elastic surface wave resonator or connecting them in a serial-parallel way. CONSTITUTION:An upper side transducer area formed by a common electrode 9-1 and an intermediate electrode 18 and a lower side transducer area formed by the intermediate electrode 18 and a common electrode 9-2 are alternately arranged. An electrode width (l) of a part to cross the propagation path of the elastic surface wave is set at lambda/4+lambda/2+nlambda (lambda: the wavelength of the surface wave, n: an integer) so that the exciting waves of the input side and the output side transducers may be a standing wave at the same phase. At such a time, the impedance of the resonator is high, and the attenuation quantity increase. In addition, capacity Cp slightly decreases the impedance, whereas, it makes resonant frequencies (fr) approach to anti-resonant frequencies (fa). As this result, the rise characteristics between the bands of the title filter are made sharper.

摘要： PURPOSE:To improve power resistance and to prolong service life by using an Al-Cu-Mg ternary alloy for a thin film strip. CONSTITUTION:A thin film stripe is made of aluminum-copper-magnesium ternary alloy in a surface acoustic wave device having the thin film stripe on a substrate on which a surface acoustic wave is propagated. In case of applying the titled device to a 3-transducer type SAW(surface acoustic wave) filter, an IDT(interdigital transducer) 2 is made of the thin film stripe 3 formed of the Ag-Cu-Mg ternary alloy on the piezoelectric substrate 1. In this case, a ternary alloy where the dope amount of Cu is 0.1-2.5wt.% and the dope amount of Mg is 0.1-1.4wt.% is preferred depending on the power given to the SAW filter and the required service life in this case and other ternary alloy where the dope amount of Cu is 1.8-2.2wt.% and the dope amount of Mg is 0.5-1.4wt.% is much preferred.
