The present invention provides the stress detection method for force sensor device with multiple axis sensor device and force sensor device employing this method, whose installation angle is arbitrary. The stress detection method includes, first and second force sensors whose detection axes are orthogonal to each other. When the detection axis of first force sensor forms angle θ with direction of detected stress Ax, and the stress component of direction perpendicular to direction of the detected stress Ax is Az, output Apx of the axis direction of first force sensor is found as Apx=αx (Ax×cos θ+Az×sin θ), and output Apz of the axis direction of the second force sensor is found as Apz=αz (Ax×sin θ+Az×cos θ), and, when αx and αz are detection sensitivity coefficients of first and second force sensors respectively, the detection sensitivity coefficient αz of second force sensor is set as αz=αx tan θ, and the detected stress Ax is found as Ax=(Apx−Apz)/αx(cos θ−tan θ×sin θ).

A dual band portable phone includes a first mobile phone system used in a first mode, a second mobile phone system used in a second mode, a storing section and a control section. The storing section has a mode area for storing a mode data indicative of a current operation mode, a first area for storing a first control channel data indicative of a first control channel used for the first mobile phone system in the first mode, and a second area for storing a second control channel data indicative of a second control channel used for the second mobile phone system in the second mode. The mode data indicates the first mode at present. The control section performs a position registration of the portable phone using the second control channel data stored in the storing section to set the second mode, when a first radio communication using the first mobile phone system becomes impossible while the first radio communication is performed in the first mode. The control section also performs a second radio communication using the second mobile phone system.

This invention intends to provide a method capable of automatically selecting one system without a large increase of production cost in a dual band mobile phone of this invention having both PHS and GSM functions. First, a common control unit (40) retrieves whether or not a SIM card (19) is mounted on a card mounting unit (9) by a SIM card retrieval circuit (41). Next, if the mounting thereof is detected and storage data is read properly from the SIM card (19), the GSM function is indicated on a mode lamp (17) so that communication is carried out by an operation of the GSM mode. On the other hand, if the mounting of the SIM card (19) cannot be detected or data cannot be read from the SIM card (19), the PHS mode is set up by a mode setting circuit (43) instead of the GSM mode. Then, the PHS mode is indicated on the mode lamp (17) so that communication is carried out by an operation of the PHS mode. A mode set to be operating is memorized in a mode memory (13) and if the power is turned ON, the system starts to operate at this memorized mode.

Radio equipment is made up of a portable telephone and a charger for charging it. Whether or not the telephone is set on the charger is determined, when a call incoming occurs while the telephone is set on the charger, the telephone alerts the user of the telephone to the call incoming via a call incoming reporter selected beforehand. If the call incoming reporter selected beforehand uses vibration, a vibration detector included in the charger detects the vibration of the telephone. Subsequently, an alert tone is output via aa speaker included in the charger. When the user hearing the alert tone picks up the telephone from the charger, the alert tone output from the speaker ends.
