Patent ID: 6949063

Claim:
A centrifugal machine of automatic balance type comprising: at least a rotor lever, to both ends of which a specimen is hooked; a rotor for supporting the rotor lever so that it moves horizontally; a lever moving means mounted within the rotor, for moving horizontally the rotor lever on central line of rotation of the rotor; a load detecting means installed on the rotor lever, for detecting loads weighed on both the ends of the rotor lever; a centrifugal motor for rotating the rotor; an electrical connection means for connecting or disconnecting the load detecting means and the lever moving means to and from an external electrical circuit of the rotor; and a controlling means for controlling the electrical connection mean so as to connect electrically the external electrical circuit to the load detecting means an the lever moving means, for calculating loads weighed on both the ends of the rotor lever by means of a detected signal provided from the load detecting means, and for controlling the lever moving means so that centrifugal forces exerted on both the ends of the rotor lever reach a balance.
