Abstract: The drone according to the embodiment has a propeller, a first direct current motor, a power source, a second direct current motor, and a control unit. The first direct current motor drives the propellers. The power source supplies power to the first direct current motor. The second direct current motor has a rotating shaft that rotates in conjunction with the rotation of a rotating shaft of the first direct current motor. The control unit controls the first direct current motor. The second direct current motor charges the power source using the current output from the second direct current motor along with the rotation of a rotating shaft of the second direct current motor.

Abstract: The present invention is directed by a capacitor comprising of dielectrics formed of a plastic film in which ceramic particles are dispersed. The plastic film is manufactured by the processes comprising the steps of coating the ceramic particles with wax, dispersing the wax-coated ceramic particles in a molten plastic, and extruding the molten plastic in which ceramic particles are dispersed into a think film.

Abstract: A patient carrying a portable self-administered health care terminal receives data regarding the energy value per nutrient to be consumed daily and the amount of energy to expend through exercise. When dining at a restaurant or other facility providing food, the patient uses a barcode reader connected to the portable terminal to read barcodes included in the menu. This barcode data is transmitted to a server in the facility. The server returns data regarding the energy value per nutrient in the selected foods. The data is automatically input into the portable terminal.
