An SMA actuation apparatus comprises a camera lens element supported on a support structure by a plurality of flexures. An SMA wire at an acute angle to the movement axis and a biasing element are connected between the support structure and the movable element. A component of the force applied by the SMA wire perpendicular to the movement axis compresses the flexures causing them to apply a force to the movable element having a component along the movement axis in the same direction as the SMA wire. An end-stop limits the movement of the movable element, and the moment applied by the end-stop to the movable element about the center of stiffness is equal to the moment applied by the SMA wire about the center of stiffness at the point when the movable element loses contact with the end-stop on contraction of the SMA wire.

A solder joint comprising a solder capture pad on a substrate having a circuit; and a lead free solder selected from the group comprising Sn—Ag—Cu solder and Sn—Ag solder adhered to the solder capture pad; the solder selected from the group comprising between 0.1 to 2.0% by weight Sb or Bi, and 0.5 to 3.0% Ag. Formation of voids at an interface between the solder and the solder capture pad is suppressed, by including Zn. Interlayer dielectric delamination is suppressed, and electromigration characteristics are greatly improved. Methods for forming solder joints using the solders.

Each permanent magnet formed in an open-letter shape is divided into a plurality of parts, the divided magnets are respectively fitted in open letter-shaped inserting portions, and ribs are respectively provided in dividing portions of the permanent magnets. Accordingly, it is possible to prevent the breakage of pole connecting portions at an outermost periphery of the rotor as adjacent inner peripheral-side permanent magnets directly come into contact with and push the outer peripheral-side permanent magnets. Alternatively, an annular nonmagnetic material is provided on an outer peripheral portion of the rotor so as to cover the open letter-shaped permanent magnets and magnetic material portions inside the open-letter portions, whereby the rotor core is made resistant against breakage, and the flux leakage is minimized.

A method for creating space in a joint, the method comprising:

• • applying force to a body part so as to distract the joint and create an intrajoint space;
  • inserting an expandable member into the intrajoint space while the expandable member is in a contracted condition;
  • expanding the expandable member within the intrajoint space; and
  • reducing the force applied to the body part so that the joint is supported on the expandable member.

A coil component that can be mounted on a printed circuit board, with a part in an aperture of the printed circuit board. The coil component includes a first flange on an upper side and a second flange. Terminal boards are on respective opposite sides of the first flange. Terminals respectively project in a direction perpendicular to an axial direction of a winding drum, from the terminal boards and bend and are inserted into through-holes of the printed circuit board. First and second touching surfaces, which are parts of a downside surface of the second flange, touch an upside surface of the printed circuit board.

A system (102) comprising a box (104) for implanting in a mamMal body part (106), which box is provided with a first electrical contact (110, 121, 114, 116, 118, 120), and a module (108) for accommodating in the box, which module is provided with a second electrical contact (122, 124, 126) for cooperation with said first electrical contact. The first electrical contact and the second electrical contact are mutually movable, at least in a stationary accommodation of the module in the box, between a contact position in which said first and second electrical contacts are electrically connected, and a non-contact position in which said first and second electrical contacts are separated from each other.

An electrical filter includes a dielectric substrate with inner and outer coils about a first region and inner and outer coils about a second region, a portion of cladding removed from wires that form the coils and coupled to electrically conductive traces on the dielectric substrate via a solder joint in a switching region. An apparatus to thermally couple a superconductive device to a metal carrier with a through-hole includes a first clamp and a vacuum pump. A composite magnetic shield for use at superconductive temperatures includes an inner layer with magnetic permeability of at least 50,000; and an outer layer with magnetic saturation field greater than 1.2 T, separated from the inner layer by an intermediate layer of dielectric. An apparatus to dissipate heat from a superconducting processor includes a metal carrier with a recess, a post that extends upwards from a base of the recess and a layer of adhesive on top of the post. Various cryogenic refrigeration systems are described.

A device for positioning a workpiece includes a socket body rotatably held on a metallic ball by an array of permanent magnets arranged into a partial socket. An air delivery system controls a flow of air passing between the magnets and the ball to alter the friction between the socket body and the ball. A positive flow of air into the socket reduces the friction, allowing the workpiece to be more easily rotated during repositioning, whereas drawing air away from the socket produces a partial vacuum which increases the friction, causing the socket body to be locked in a single position on the ball.

A compression molding machine includes a wheel mounted for rotation around a horizontal axis and a plurality of angularly spaced molds disposed around the wheel. Each of the molds includes a first mold segment and a second mold segment disposed radially outwardly of the first mold segment. Each of the second mold segments is movable radially with respect to the associated first mold segment between a radially inner closed position with the first mold segment for compression molding a plastic article, and a radially outer open position spaced from the associated first mold segment for removing a molded article from the mold and placing a mold charge into the mold.

Arrangement and method for the construction-time use of an elevator, which arrangement comprises an elevator car (2), hoisting roping (4), a hoisting machine fitted to move the elevator car via the hoisting roping (4), which hoisting machine is preferably disposed on the machine room level (22) at the top end of the elevator hoistway, a counterweight (56), and which elevator comprises compensating roping (10), which compensating roping is connected to the supply storage (16) of the compensating roping. In the arrangement, the compensating roping (10) is connected to the elevator car via a diverting pulley (28) on the elevator car and to the counterweight (56) via a diverting pulley (58) on the counterweight (56). In the method one or more jumps of the machine room level are performed, and the additional rope needed for a jump of the machine room level is taken from the supply storage of the compensating roping. The construction-time roping of the elevator is arranged such that the compensating roping is connected to the elevator car (2) via the diverting pulley (28) on the elevator car (2) and to the counterweight (56) via the diverting pulley (58) on the counterweight (56).
