Abstract: An implantable left ventricular assist device using a cylindrical cam is provided, which is produced in a compact and module form and implanted in a patient who suffers from an acute cardiac insufficiency, to thereby enable oxygen to be supplied smoothly toward the heart of the patient and reconstruct the declined function of the heart. The implantable left ventricular assist device includes an actuator for generating a linearly reciprocating driving force, a pusher plate which performs a linearly reciprocating motion by the actuator, a blood sac which is contracted and expanded due to compression by reciprocating the pusher plate and the restoration of a sac itself, and a chamber for accommodating the blood sac, the pusher plate and the actuator, combining the same physically, and protecting the same within the body of a patient.

Abstract: A six-degree-of-freedom parallel mechanism is provided for expanding a grade of a spindle. The parallel mechanism has a spindle that turns round a workpiece at a tilting angle of 90.degree. in a workspace, to thereby allow a machining for both vertical and horizontal planes of the workpiece, and a vertical turning process, by a single machining center. A six-axis multi-machining type machining center embodying the parallel mechanism of the present invention is also disclosed. An over-actuated multi-machining type machining center further including over-actuated actuators is presented to solve a problem of driving joints' singularity caused by the parallel mechanism.
