Abstract:
To separate resin molded parts that are used for a push button switch member with less light leakage from the side faces and less trouble in key operation, easily, a resin molded body comprises one or more resin molded parts for a push button switch member, a frame surrounding the outside of the resin molded parts, one or more gates connecting a plurality of the resin molded parts each other or the resin molded part to the frame and one or more runners crossing the longitudinal direction of the gates, wherein the gates are connected at the back faces of the resin molded parts not to be coated with light shielding paint, and wherein the runners are connected to the gates on the same surfaces as the resin molded parts are connected to and are connecting the opposing sides of the frame.
Abstract:
An electric device generates a predetermined amount of heat in the event of a malfunction. The electric device is protected from overheating in that it is arranged, with a fuse in a circuit, such that the fuse and the electric device are thermally coupled to one another, so that the generation of the amount of heat by the electric device causes a fusible material in the fuse to melt. In this manner, the current terminal path of the electric device is interrupted.
Abstract:
The invention provides a connection grid, comprising at least a pair of arms for fixing a fuse to the grid via its longitudinal ends. Each of the arms comprises a concave portion forming a cradle for receiving one of the longitudinal ends of the fuse. A method for producing this grid and a device for implementing this method are also provided.
Abstract:
A housing assembly 30 is provided for a permanent magnet motor. The housing assembly includes a ferrous flux ring structure 38 having an exterior 39 and an interior 36. Magnet structure 34 is carried within the interior of the flux ring structure 38. A plastic housing 32 substantially encapsulates the exterior of the flux ring structure 38 and at least portions of the magnet structure 34. A bearing 42 may be provided in a closed end of the housing 32.
Abstract:
A MEMS thermal switch is disclosed which couples a hot, expanding beam to a cool flexor beam using a slideably engaged tether, and bends the cool, flexor beam by the expansion of the hot beam. A rigidly engaged tether ties the distal ends of the hot, expanding beam and the cool, flexor beam together, whereas the slideably engaged tether allows the hot, expanding beam to elongate with respect to the cool, flexor beam, without loading the slideably engaged tether with a large shear force. As a result, the material of the tether can be made stiffer, and therefore transmit the bending force of the hot, expanding beam more efficiently to the cool, flexor beam.

Abstract:
A computer hard drive assembly device is described which can include a turntable, a motor, and a control. The turntable can include a platform configured to secure computer hard drive components to the turntable. The motor can be coupled to the turntable by a rotating drive shaft which allows the motor to rotate the turntable. The control can be coupled to the motor and is coupled to engage the motor. A method for computer hard drive assembly using the device is also provided.
Abstract:
A method and apparatus for assembling an armature subassembly to a relay subassembly which includes (a) positioning the armature subassembly so the proximal end of the contactor is adjacent the upper wall of the relay frame and the armature is adjacent the front edge of the frame; (b) mechanically moving and holding the distal end of the contactor blade against the relay subassembly so that the armature is flush against the front edge of the frame; (c) mechanically moving and holding the proximal end of the contactor blade against the upper wall of the frame without inducing lateral movement or stress in the contactor blade; (d) relieving position-affecting stress on the contactor blade; (e) releasing the distal end of the contactor blade to assume a rest position so that the armature and front edge forms a gap; and (f) welding the proximal end of the contactor to the frame wall.
Abstract:
Paramagnetic articles such as a stem (14) and an armature (17) are placed into mutual coextensive alignment with a gap (19) of a predetermined width between adjacent portions of such articles. To repetitively establish the predetermined gap between successive groups of such articles, a first of such articles is guided tangentially into a magnetic field. A resulting force on such article (14) draws the article against a first stop surface. The article becomes magnetically polarized, such that when the second article, such as the armature (17) is guided into coextensive alignment with the first article, the second article becomes attracted to the first article to be drawn against a stop surface opposite to and spaced from the first stop surface by a dimension equal to the predetermined gap width.
