Abstract: A food mixing apparatus includes a mixing container for receiving food, a first support frame for supporting the mixing container to be rotatable about a first axis: X, a first drive mechanism disposed in the first support frame for rotating the mixing container, a second support frame for supporting the first support frame to be variable in posture relative to the second support frame, and a second drive mechanism for displacing the first support frame from one posture to another.

Abstract: An electric cleaning device circulates exhaust air from an electric blower to a floor intake tool. The exhaust air passes through an exhaust guide, formed as one element, in a main cleaning device unit from the electric blower through a hose to the floor intake tool. The exhaust guide is a resilient unitary resin part with sufficient resilience to permit compression for installation. The springback of the exhaust guide seals the exhaust path against leakage.

Abstract: A food mixing apparatus includes a main housing, a mixing container for receiving food, and having a central axis: Y, a rotor ring surrounding the mixing container, the rotor ring being fixed to the mixing container and having a central axis: X extending at an angle to the central axis: Y of the mixing container, and a support roller mechanism attached to the main housing, the support roller mechanism supporting the rotor ring at two points only from below to rotate the rotor ring about the axis: X. An aerating tube communicating with an opening formed in a bottom surface of the mixing container extends coaxially with the axis: X of the rotor ring. The aerating tube communicates with a blast duct mounted in the main housing.

Abstract: A vacuum cleaner comprising: a main body having a dust collecting chamber and a motor chamber; a cover for the dust collecting chamber; and an inlet pipe formed on the dust collecting chamber. A lever is provided within the dust collecting chamber, the lever being swingable between a position where one end of the lever is positioned between an opening edge of the dust collecting chamber and the cover to prevent the cover from closing and a position where the lever enables the cover to close. It is not possible to attach the cover to the cleaner in the state where the dust collecting bag is detached so that it is possible to securely prevent misuse of the cleaner in the state where the dust collecting bag is not attached.

Abstract: An electric vacuum cleaner comprising a floor nozzle connected to a lower part of a main body of the electric vacuum cleaner and having a suction opening opened on a lower surface of the floor nozzle, a rotary brush disposed in the suction opening, a driving source, a power transmission system which transmits power from the driving source to the rotary brush, and a changeover unit which connects or disconnects power transmission of the power transmission system, wherein the changeover unit is provided with an operation pedal, which is manipulated to connect or disconnect the power, on a rear portion of the floor nozzle. It is possible for an operator to instantaneously turn on and off the driving of the rotary brush only by stepping down or lifting up the pedal while gripping the handle at rear side of the main body of the cleaner without stopping the movement of the cleaner.

Abstract: A method and an apparatus for clearing burrs from products fabricated from metal stock. The burr of a product is used as one electrode, and another electrode is formed by extending an electrode material along, and apart from, the burr. A voltage is applied across the electrode to generate an arc between them. In the meanwhile, a magnetic field having a magnetic flux flow crossing the arc is formed to drive the arc along the burr by an electromagnetic force whereby the burr is melted and removed from the product.
