A reciprocating-type electric shaver including an outer cutter having an inverted U shape as seen from a side thereof and an inner cutter making a reciprocating motion while making sliding contact with an inside surface of outer cutter, and further including: an oscillator making a reciprocating motion by a motor installed inside the main body of the shaver; a central shaft provided in an upright position on the oscillator and rises toward the inside of the outer cutter; an inner cutter holder disposed in a slidable manner on the central shaft so that the inner cutter holder holds the inner cutter thereon and the inner cutter swings about a straight line that is perpendicular to the reciprocating direction of the inner cutter; and a spring compressedly installed between the oscillator and the inner cutter holder.

A gyroscopic exercise device has a pair of handles attached to a housing. A user holds and rotates the handles along cone-like paths causing precession of a rotor, which is rotating about its spin axis, to provide resistance to the user. The device has an axle disc that holds ends of an axle of the rotor. The periphery of the axle disc and the ends of the rotor axle are within a circular race in the housing. A retracting spool allows pull starting. An optional motor attached to the axle disc has a wheel for rotating the rotor about a spin axis by a temporary supply of power from included batteries in one of the handles. An optional abdominal rolling ring provides abdominal exercise.

A motor attached to the axle disc has a wheel for rotating the rotor about a spin axis by a temporary supply of power from included batteries in one of the handles. The batteries are in between two opposite springs in one of the handles and normally biased away from an electrical contact until the user pushes them through an end pin to overcome the bias.

An integrated motor pump for use in medical devices and the like.

In a zoom lens of a fixed total length, at the time of changing the magnification from the wide-angle end toward the telephoto end, the first lens group is anchored while the second lens group is moved, and the third and fourth lens groups are moved so as to be located at the object side of the telephoto end relative to the wide-angle end, such that: the interval between the second and third lens groups is decreased at the telephoto end relative to the wide-angle end; the interval between the third and fourth lens groups is increased at the telephoto end relative to the wide-angle end; and the interval between the fourth and fifth lens groups is increased at the telephoto end relative to the wide-angle end, and at the time of focusing a near object point from a remote object point, the second lens group is moved.

The invention relates to a rail type belt conveyor. The rail type belt conveyor comprises a support, a machine head frame, a machine tail frame, an upper guide rail, a lower guide rail, a towing trolley, a rubber belt, a steel wire rope, closed-loop systems, a driving roller, an elevating supporting roller set, a redirection frame and a triangular frame. The elevating supporting roller set is mounted at the position, close to the machine head frame, of the support, the redirection frame is mounted on the machine tail frame, a redirection drum is arranged on the machine head frame, and a tensioning vehicle is arranged at the position, close to one side of the redirection drum, of the support; and the triangular frame is arranged at the position, between the two closed-loop systems, of the support, and the rubber belt is wound around the elevating supporting roller set, the redirection drum, the tensioning vehicle, a supporting roller on the redirection frame and a supporting roller on the triangular frame. The rail type belt conveyor has the beneficial effects that a traditional rubber belt machine structure is removed, a supporting belt trolley is used for replacing a part of a common supporting roller, the cost and the mounting cost are reduced, and revolutionary innovation is brought to bulk conveying.
