Abstract: There is provided a portable electronic device capable of being immediately operated without the use of a battery even when the battery reaches exhaustion. An electricity generating unit 131 is embedded in the portable electronic device. The electricity generating unit 131 has a mechanism to pull out a pull line 113 wound around a pulley 135 to wind up a spiral spring 133 and a mechanism to transfer torque occurring when the spiral spring 133 is released and to rotate the motor at high speed. An output voltage from the motor 142 is adjusted and smoothed by a constant voltage circuit and is directly supplied as power to power consuming components. The portable electronic device connecting two flips can wind up the spiral spring 133 by opening and closing the two flips.

Abstract: A vehicle load control system, in which information on the cargo loading condition of a moving vehicle is obtained through communication between the moving vehicle and a control center via a communication network to provide centralized control of efficient cargo loading operation. A vehicle load control system provides centralized control of efficient cargo loading operation through communication between a moving vehicle (100) and a control center (120) via a communication network (110). The moving vehicle (100) includes a radio section (101) for receiving a load data acquisition request signal and transmitting measured load data determined by at least one distance sensor (105) in the luggage compartment and location data of the vehicle.

Abstract: Vehicles or ships each carry a magnetic force line sensor, a GPS position detector, and a data transmitter and travel within an observation area transmitting magnetic field data and position data to an earthquake prediction center. A telluric current induction field estimation unit of the earthquake prediction center estimates telluric current induction fields based on the received observation data. A telluric current estimation unit estimates telluric currents based on the results of estimating the telluric current induction fields. A telluric current induction field intensity change pattern generation unit generates patterns indicating the change over time of the intensity of telluric current induction fields. An earthquake prediction unit analyzes the state of distribution of the telluric currents and the patterns of change in the intensities of the telluric current induction fields and estimates a seismofocal zone, seismic intensity, and time of occurrence of a seismic event.

Abstract: Vehicles (1-1) or ships (1-2) each carry a magnetic force line sensor (11), a GPS position detector (12), and a data transmitter (13) and travel within an observation area transmitting magnetic field data and position data of each point to an earthquake prediction center (4). A telluric current induction field estimation unit (43) of the earthquake prediction center (4) estimates telluric current induction fields based on the observation data that it receives and collects. A telluric current estimation unit (44) estimates telluric currents based on the results of estimating the telluric current induction fields. A telluric current induction field intensity change pattern generation unit (45) generates patterns that indicate the change over time of the intensity of telluric current induction fields.

Abstract: An image printing system using a cellular phone with camera, which offers useful services for a user who possesses a cellular phone with camera but does not have means for easily printing out images taken by the cellular phone. The image printing system using a cellular phone with camera includes a means for connecting a cellular phone with camera to a portrait seal printing machine. Image data of an image taken by the cellular phone with camera is fed into the portrait seal printing machine, and the portrait seal printing machine produces and prints out portrait seals based on the image data.
