To provide a golf club head in which a sole portion has a high rigidity. A weight material is mounted near a central part of the sole portion in the fore-to-aft direction, and a rib extends in the toe-to-heel direction. Since the sole portion has high rigidity in the toe-to-heel direction, there is less deformation of the head in the toe-to-heel direction when hitting the ball, thereby suppressing the vibration of the sole portion. An elastic body is filled in a recess portion and closely contacted with the weight material, whereby the vibration of the sole portion is absorbed by the elastic body.

A metal wood golf club head is provided having a front face with an impact zone including a compliant area. Preferably, the compliant area is disposed in an upper portion of the front face. Preferably, a through-slit is provided in the front face to form the compliant area. The through-slit may be an elongated slot substantially parallel to a top of the front face and may include an elastomeric reinforcement. The compliant area creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The compliant area upwardly shifts the coefficient of restitution to the geometric center of the face and thereby increases the carry distance of a golf ball hit off the club head.

A hydraulically assisted actuator in a handle connects with a catheter having a deflectable distal ablation tip. The hydraulic actuator translates small mechanical movement by a clinician into large travel movements of connected steering cables and increased tension in the ablation tip for greater deflection. The hydraulic system further dampens the return of the ablation tip from a deflected position to an equilibrium position. The hydraulic actuation system is also incorporated into a set of foot pedals.

PCT No. PCT / EP97 / 06498 Sec. 371 Date May 20, 1999 Sec. 102(e) Date May 20, 1999 PCT Filed Nov. 20, 1997 PCT Pub. No. WO98 / 23869 PCT Pub. Date Jun. 4, 1998A microvalve includes a micromechanically structured chip defining a valve seat with a flow opening therethrough, an elastic suspension device and an edge region. A valve plate is defined by a piezoelectric actuator and is connected to the edge region of the micromechanically structured chip. The longitudinal dimension of the piezoelectric actuator are able to be changed by the application of an electric voltage. A decrease in the longitudinal dimension of the piezoelectric actuator caused by the application of an electric voltage is mechanically converted into a movement of the valve plate relative to the valve seat essentially at a right angle to the longitudinal direction. The connection of the piezoelectric actuator with the edge region of the micromechanically structured chip and the suspension device causes the conversion. Thus, the valve plate will open or close the flow opening in the valve seat.

Opposable surgical clamp members having opposable resilient pads with wedge-shaped and cylindrical protrusions extending from the surfaces of the pads and the use of such members for occluding vessels and other tubular body structures are described. The protrusions are arranged such that when the members are moved toward one another, the protrusions of one pad interdigitate with the protrusions of the other pad. Upon engagement with a vessel, portions of the vessel are forced into the interdigital spaces providing for improved gripping of the vessel. The protrusions also resist lateral or transverse movement of a clamped vessel relative to the pads. The existence of through holes under the pad surface alters the relative resiliency of the pad, allowing for an overall pad resiliency that minimizes trauma to a clamped vessel while allowing the local resiliency of the protrusions themselves to be of a hardness to avoid excessive deflection and retain the desired shape and gripping ability.

PCT No. PCT / EP97 / 06344 Sec. 371 Date May 20, 1999 Sec. 102(e) Date May 20, 1999 PCT Filed Nov. 13, 1997 PCT Pub. No. WO98 / 23868 PCT Pub. Date Jun. 4, 1998A microvalve has a base element provided with a passage opening, a tappet, a suspension device for guiding the tappet, and a piezoelectric actuator for actuating the tappet. The suspension device guides the tappet relative to the base element in such a way that the passage opening can be closed or opened by the tappet. The longitudinal dimensions of the piezoelectric actuator can be changed by the application of an electric voltage. Longitudinally spaced ends of the piezoelectric actuator are connected to longitudinally spaced ends of the suspension device in such a way that the suspension device provides a way for mechanical translation between the actuator and the tappet. A change in the longitudinal dimensions of the piezoelectric actuator caused by the application of an electric voltage to the piezoelectric actuator is mechanically translated by the suspension device into a movement of the tappet essentially at right angles to the longitudinal direction so that the passage opening will be opened or closed. In addition, the suspension device is secured to the base element with the aid of a hinge-like element. At least two spaced points are used to secure the suspension device to the base element.

A labelling device includes a linearly displaceable piston operably connectable to a moving mechanism for moving the piston from a resting position to a labelling position. A label carrying mechanism is arranged at the distal end of the piston for carrying an adhesive label and affixing the adhesive label to an object via physical contact at the labelling position of the piston. A force-switching-state system is provided to maintain the piston in relation to the moving mechanism in an attracting force state and the piston moves with the moving mechanism. The physical contact creates an opposite repelling force from the object onto the label carrying mechanism causing separation of the displaceable piston from the moving mechanism. This separation causes a change of the force state of the displaceable piston from an attracting to a repelling force state, causing the linearly displaceable piston to move back to the resting position.

A self-adjusting non-contact seal for sealing the circumferential gap between a first machine component and a second machine component includes structure which undergoes wear in the event of inadvertent contact with one of the machine components in such a way as to allow a reset of its radial distance from such machine component, compared to initial installation tolerances, while minimizing leakage.
