Provided is a medicinal agent for medical applications, which can act on the function of a target cell specifically. The medicinal agent for medical applications comprises: a cell-incorporated substance that can be incorporated into a target cell specifically; and an acting substance that can act on the function of the target cell and is bound to the cell-incorporated substance.

Medicinal agent for medical applications

An ultrasonic motor comprises a piezo-electric element and electrode patterns disposed on a surface of the piezo-electric element at nearly equal intervals in a multiple of four. A vibrating member is disposed on another surface of and electrically connected to the piezo-electric element. A moving member is movably disposed on the vibrating member. First projections which frictionally drive the moving member by expansion and contraction movement of the piezo-electric element are disposed on a surface of the vibrating member near every other one of the boundaries of the electrode patterns of the piezo-electric element. Second projections are provided at each intermediate position between the first projections near all of the boundaries of the electrode patterns other than the boundaries near which the first projections are provided for adjusting the vibrating conditions of the vibrating member. The second projections have a different height from the first projection and do not frictionally drive the moving member. A pressure-regulating member urges the moving member into pressure contact with the vibrating member at a predetermined pressure.

Ultrasonic motor and electronic apparatus provided with an ultrasonic

An ultrasonic motor comprises a piezoelectric element having first and second surfaces. Electric patterns are disposed on the first surface of the piezoelectric element at nearly equal intervals in a multiple of four, with each pair of two neighboring electrode pattern corresponding to a region of the piezoelectric element which has an alternately reversed direction of polarization. First and second circuit devices short-circuit every other one of the electrode patterns to form two electrode pattern groups. A vibrating member is disposed on the second surface of and electrically connected to the piezoelectric element. Projections are disposed on the surface of the vibrating member near every other one of the boundaries of the electrode patterns. An oscillation driving circuit detects oscillation data from one of the electrode patterns short-circuited by the first circuit device, performs phase adjustment and amplification of the vibrating wave generated by the piezoelectric element, and inputs a driving signal to one of the electrode patterns short-circuited by the second circuit device. A moving member is movably disposed on the vibrating member, and a pressure-regulating member urges the moving member into pressure contact with the vibrating member.

An ultrasonic motor utilizing flexural travelling wave components. A ball bearing is constituted by the inner ring, the balls, and an outer ring provided with a groove similar to the ball positioning groove of the inner ring, at a position where the ball are interposed. A rotor is provided inside the amplifying projections which are formed in the vibration member. A coil spring is provided in order to bring the rotor and the projections of the vibration member into pressure contact with each other. A spring pressing seat having a groove for receiving the other end of the coil spring is fixed to the support pin, with the coil spring and the support pin centered. The coil spring receiving groove of the inner ring and the coil spring are positioned so as not to share the same vertical plane with the ball. In this manner the thickness of the ultrasonic motor can be reduced.
