    摘要： A friction drive actuator, comprising: a vibration member which is configured to be driven to vibrate by expansion and contraction of a piezoelectric displacement portion which is included in the vibration member and driven by a driving signal; a sliding member which is in contact with the vibration member and is driven by the vibration member in a first direction with respect to the vibration member; a pressing member which causes the vibration member and the sliding member to come into a pressure contact therebetween; and a control member which is provided on each of the vibration member and the sliding member at a contact portion therebetween for controlling a relative movement of the sliding member with respect to the vibration member in a direction perpendicular to the first direction when the vibration member and the sliding member are pressedly contacted with each other by the pressing member.

    摘要： A vest for a human body has an air core coupled to a pulsator operable to subject the vest to pulses of air which applies and releases high frequency pressure forces to the body. The pulsator has two diaphragms connected to a brushless electric dc motor with rotary to reciprocating linear motion transmitting mechanisms comprising scotch yokes having anti-lash assemblies operable to generate air pulses in an air pulsing chamber. The diaphragms also increase the pressure in a manifold chamber. A check valve connects the manifold chamber with a pulsing chamber to allow pressurized air to flow from the manifold chamber into the pulsing chamber. An air flow control valve in communication with the manifold chamber is used to adjust the pressure of the air in the manifold and pulsing chambers. A programmable motor controller adjusts the duration of operation and speed of the motor to vary the operational time and frequency of the air pulses.

    摘要： A three-ring needle bearing with a central support shaft, a center ring around the shaft, an outer ring around the center ring, and an inner needle array between the shaft of the center ring and an outer needle array between the center ring and the outer ring. An axial disk at one axial end of the bearing push fit on the center ring and radially projecting past both the inner needle array and the outer needle array for axially supporting them. The outer ring having bend-in moldings which past the axial disk at one end and past the end of the outer needle array at the other end. A drive shaft rotates the center ring, which is eccentric with reference to the support shaft.

    摘要： An oscillating power unit for use with a variety of tools and equipment that are vibrated in their operation. An inertial mass rocking about a fixed pivot is driven by an orbital motion eccentric mechanism in such a manner that the effective power is concentrated along one axis of motion and minimized in all other directions. The eccentric drive has a variable throw that is easily adjusted to selectively vary the oscillating power output when the unit is installed in an operating assembly without dismantling the structure, although all moving parts except the drive shaft are fully enclosed.
