An electric-powered vehicle includes electric-powered drivers for driving wheels, a controller for controlling the electric-powered drivers to generate an assisting driving force in accordance with a vehicle operating force by an operator, and a brake-operation unit for applying braking forces on the wheels. The second secure computing apparatus uses a segment s that satisfies the relation mA=s*t, a logic circuit function f and the data W to generate data T in which a logic circuit function f, which is the logic circuit function fin which the segment s is substituted, is concealed, and transmits the data T to the first secure computing apparatus. An oscillator is positioned within the platform and is configured to impart an oscillating force on the body. In an outside configuration composed of the head portion and the first and second terminals, a contour between a location of the second terminal and a location of the first terminal is formed axis-symmetrically with respect to an axis of the head portion. 1 to 100 microns, cross-linked proteins at the interface of said droplets and any polar, low molecular compound in between the cross-linked protein interfaces.
