An electronic assembly includes a semiconductor device mounted on a printed circuit board, a leaf spring and a cooling plate. A plurality of fasteners pass through co-axial apertures of the leaf spring, the printed circuit board and the cooling plate, such that a contact surface of the leaf spring imparts a force on the semiconductor device to retain the semiconductor device in a thermally conductive position with respect to the cooling plate. A positive cooling effect is achieved regardless of mounting conditions including orientation of the electronic assembly, and the position of the semiconductor device on the cooling plate.

An X-Y stage system is disclosed which is easy to assemble and compact or slim in construction. Both the X- and Y-stages are allowed to move without getting influence from the magnetic force created by the field magnets. The X-Y stage system has an X-stage movable relatively to a bed through a linear motion guide unit in an X-direction, and a Y-stage movable relatively to the X-stage through another linear motion guide unit in a Y-direction. The linear motors to force the X- and Y-stages are composed of paired field magnets of secondary side held to the bed and the Y-stage, respectively, and armature windings of primary side supported on the opposite sides of the X-stage in a way lying in clearances between the opposing field magnets.

The present invention discloses a folding bicycle, wherein a folding joint is installed on the beam, and the rear fork is hinged with the frame via a hinge axle, on the rear fork is installed a support bar which rests against the frame; and wherein the beam is S-shaped, and the hinge axle is tilted by an acute angle with respect to the central axle of the frame. When the bicycle is folded, the front and rear wheels are located separately, each at one side of the beam and within the concave section of the S-shaped beam, so that the bicycle is more compact and has a less width after being folded.

A strip is provided with a series of housings for a like number of terminals to which conductor wires accede thrust by a tool in order to establish a connection, by means of displacing the conductor wires over the terminals. Each housing or chamber is independent of those adjacent, the separation being constituted by means of transversal partitions, which makes possible the pouring of a sealing gel into the respective housing chamber up to a level which is at a height lower than the entrance step of the conductor wires and above the edge of the terminals, with the objective that both said terminals and the connections thereof with the conductors be immersed in the sealing gel in order to prevent oxidation on the connections.

A one-piece dental implant having a longitudinal axis comprises a head portion at a first end of the implant, a tip portion at a second end of the implant and a body portion between the head portion and the tip portion. The body portion has a first portion proximate the head portion with a plurality of longitudinal grooves substantially parallel to the longitudinal axis and a second portion proximate the tip portion having a substantially circumferential groove, wherein the outer diameter of the first portion is greater than the outer diameter of the second portion. The first and second portions are for being embedded in the jaw bone. The dental implant is preferably dimensioned to conform to the natural shape of the cervical ⅓ of the root of the tooth being replaced, and to the natural relationship between the cemento-enamel junction of the tooth being replaced and to minimize adverse immunological responses by the jaw bone during healing, thereby improving the aesthetic appearance of the implant and prosthetic tooth attached thereto. A dental implant and prosthetic tooth system is also disclosed, wherein the prosthetic tooth conforms to the shape of the cervical ⅓ of the crown of the tooth being replaced. A method for implanting a dental implant through use of a reference, is also disclosed.

A generator of time-variable magnetic fields of a magnetic resonance device having an examination space for registering at least one area to be examined of an item being examined has the following features: the conductors of a gradient coil arrangement of the generator define an area at least partially surrounding the examination space, said area contains at least a partial area which is free from conductors of the gradient coil arrangement and which contains conductors of a radio frequency antenna of the generator, and a field flowback space, inter alia for fields of the radio frequency antenna, extends proceeding from the partial area away from the examination space and is delimited beyond said partial area by a radio frequency shield.

A floor panel and method of manufacturing wherein each panel comprises a sheet having at least two stiffening members extending from the lower surface and substantially the length of the sheet. A bead is defined along one of the stiffening members while a tab is defined along the other stiffening member. Clips are provided to fasten the bead and tab in a locking relationship to hold the sheet in position. A flange formed at one end of the panel is received within a recess formed at an opposite end of another panel to automatically space one panel from another.

A semiconductor package is disclosed that bonds a semiconductor chip to a leadframe using a flip chip technology. An exemplary semiconductor package includes a semiconductor chip having a plurality of input-output pads at an active surface thereof. A plurality of leads are superimposed by the bond pads and active surface of the semiconductor chip. The leads have at least one exposed surface at a bottom surface of the package body. A plurality of conductive connecting means electrically connect the input-output pads of the chip to the leads. A package body is formed over the semiconductor chip and the conductive connecting means. The bottom surface portions of the leads are exposed to the outside.

A multi-layer gate stack structure of a field-effect transistor device is fabricated by providing a gate electrode layer stack with a polysilicon layer, a transition metal interface layer, a nitride barrier layer and then a metal layer on a gate dielectric, wherein the transition metal is titanium, tantalum or cobalt. Patterning the gate electrode layer stack comprises a step of patterning the metal layer and the barrier layer with an etch stop on the surface of the interface layer. Exposed portions of the interface layer are removed and the remaining portions are pulled back from the sidewalls of the gate stack structure leaving divots extending along the sidewalls of the gate stack structure between the barrier layer and the polysilicon layer. A nitride liner encapsulating the metal layer, the barrier layer and the interface layer fills the divots left by the pulled-back interface layer. The nitride liner is opened before the polysilicon layer is patterned. As the requirement for an overetch into the polysilicon layer during the etch of the metal layer, the barrier layer and the interface layer is omitted, the height of the polysilicon layer can be reduced. The aspect ration of the gate stack structure is improved, the feasibility of pattern and fill processes enhanced and the range of an angle under which implants can be performed is extended.
