Abstract: In a soft grip head, a soft grip unit having the soft grip head, and a grip device having the soft grip unit, the soft grip head has a suction pad and the suction pad makes contact with an object. The suction pad includes a sidewall and a plurality of suction cells. The sidewall divides the suction pad into a plurality of spaces, and both ends of each of the spaces are open. A plurality of suction cells is respectively formed by the spaces divided by the sidewall. The suction pad includes a material having a stiffness along an axial direction smaller than a stiffness along a width direction. The suction cells extend along the axial direction, and the width direction is substantially perpendicular to the axial direction.

Abstract: In a soft grip unit, a grip device having the soft grip unit, and a driving method of the grip device, the soft grip unit includes a flexible cover, a particle, a negative pressure generator and a flexible supporting part. The flexible cover has a gripping surface on which a target object is attached and a reference surface coupled with the gripping surface. The particle is received by the receiving space, and transformed corresponding to a shape of the target object. The negative pressure generator is connected to the flexible cover. The negative pressure generator absorbs an air of the receiving space to contract the flexible cover. The flexible supporting part is tightly attached to the reference surface, and transformed at the same time when the flexible cover is pressurized and transformed by the target object.

Abstract: The present invention provides an air-foil bearing including a damper body, a front welding plate, and a front top foil for increasing durability, and which has a first bending mode. The damper body includes a front body portion, a rear body portion, and a front protruded portion protruded upward from the front body portion to have a flat protruded surface, and the front welding plate includes a front first contact portion in surface contact with a top surface of the front protruded portion and a front second contact portion which is a portion that is bent from the front first contact portion in surface contact with the front welding plate.

Abstract: A split combo bearing including a damper body that has a through-hole through which a rotor shaft passes, a cover that covers both axial sides of the damper body and a predetermined area of the outer circumference of the damper body, a thrust bump that is fixed to the side of the cover, which is in contact with the impeller on a rotor shaft, and is arranged circumferentially around the through-hole, a thrust top foil that is axially fixed to the outermost side of the thrust bump, and a radial top foil that is formed to cover the rotor shaft, and is disposed between the outer side of the rotor shaft and the inner side of the through-hole of the damper body.
