Abstract: An electronic equipment system includes a housing 20 and a plurality of modules 31 to 35, which are removably built in and fixed to the housing 20. The modules 31 to 34 includes a liquid crystal display 31a; a graphic control circuit 32a1 and a navigation control circuit 32a2; an MD unit 33a; and a CD unit 34a, respectively. The module 35 is formed through integration of control sections, such as constant-voltage circuits for power supply, which achieve a function that is common among the graphic control circuit and the navigation control circuit, the MD unit, and the CD unit. Thus, it becomes possible to replace only necessary one among the modules 31 to 34, thereby reducing cost necessary for upgrading of the system.

Abstract: A foot pad has an elastic conical body and at least one elastic rib. The elastic conical body defines a connecting surface and an outer conical surface. The connecting surface defines a hollow portion, and the elastic rib integrally connects to the elastic conical body at a surface of the hollow portion. The outer conical surface has a root portion connecting with an outer edge of the connecting surface. A thickness of the elastic conical body at the root portion of the outer conical surface is greater than a thickness of the elastic conical body at other portions of the outer conical surface. Elasticity of the foot pad is thereby increased so as to enlarge a contact area contacting an outer supporting surface, so that an anti-skid effect is improved and the foot pad is capable of absorbing a deformation of an electronic product.

Abstract: A simplified installation design for an in-use cover for an electrical outlet includes conical mounting screw holes in the outlet box and movement-restricting guides to ensure the mounting screw aligns with the mounting screw holes. Angled side mounting screw holes allow the outlet box to be installed with screws from within the box rather than the conventional nails outside the box. In particular embodiments of the invention, prongs, screws, clamps, heat stakes or other attachment components extend from the back of the insert to allow for pre-installment attachment of the electrical device directly to the insert. This also simplifies installation of the recessed in-use covers. Adaptors may optionally be included to allow the device to be adapted for use with a variety of sizes and shapes of electrical devices. An alternate embodiment of the invention includes a recessed in-use outlet formed of an electrical box, a receptacle, a cover plate and a cover to allow for simple installation with fewer parts.

Abstract: A nanoscale grasping device comprising at least three electrostatically actuated grasping elements. The use of at least three elements, which together define a plane, allows an object to be grasped more accurately, more easily held, and more readily manipulated. The grasping elements preferably comprise conductive nanotubes which are grown at specific points on a substrate (e.g., directly on an electrode), using chemical vapor deposition (“CVD”) techniques, thereby allowing the grasping device to be manufactured with greater control. Different types of electrostatic forces may be used to open or close the grasping tool. Such attractive and repulsive forces can be created through the application of either a constant voltage or an oscillating voltage.

Abstract: An insert bridges a junction box to provide a continuous path between consecutive pipes of an electrical wiring guideway. The insert includes a generally tubular body having a first end and a second end. The insert has a length that is sized to bridge a gap across the junction box and a diameter that is sized for sliding into a pipe of the electrical wiring guideway. A first flange surrounds the generally tubular body and is spaced from the first end thereof. A second flange surrounds the generally tubular body and is spaced from the second end thereof. The flanges abut opposing inner walls of the junction box to ensure that the insert is not lost into a pipe. A slit extends along the length of the insert to allow for removal of the insert once the electrical wiring has been laid.

Abstract: A line carrier for supporting wiring and tubing extending between a vehicle and a slide-out room of the vehicle comprises an elongated strip of a flexible and material having a first end secured to a skirt of the slide-out room which extends below the vehicle floor and a second end which is pivotally mounted on a pivot pin extending below the vehicle floor.

The tank is made of a corrosion-proof composite material and a radiator is provided for cooling the oil.

Abstract: In the present invention, a frame for mounting a fiber optic taper and a CCD chip in optical contact comprises a resilient support for supporting the fiber optic taper adjacent the CCD chip, means for lowering the fiber optic taper towards the CCD chip and means for applying pressure to urge the fiber optic taper onto the CCD chip. The weight of the fiber optic taper is supported by the resilient support as it is lowered into contact with the chip. Once in engagement with the CCD chip, the fiber optic taper can be pressed against the CCD chip to provide a positive pressure in excess of that due to its weight. As the support is resilient, it provides resistance to the positive pressure, thereby preventing the pressure on the CCD chip from becoming great enough to cause damage to the fragile CCD chip.
