  • Patent number: 5942728
    Abstract: A waterproof case for receiving a circuit board includes a housing, a cover and a waterproof washer. The inner edge of the opening end of the housing is formed into a slant inner edge, and a closed end of the housing is provided with supporting members for supporting the circuit board. The cover is attached to the opening end of the housing, and has an annular flange for mounting the waterproof washer, mounting members for mounting the circuit board, and a through hole for wires. When fixing the cover onto the housing by appropriate fastening members, the waterproof washer will be pushed by the cover and abut against the slant inner edge, and thereby achieve the seal between the cover and the housing.

  • Patent number: 5918121
    Abstract: A method for making planar silicon-based inductor structure with improved Q is disclosed. This method includes the steps of: (a) providing a lightly-doped P-type substrate as a starting wafer; (b) forming a preliminary oxide layer on the lightly-doped P-type substrate; (c) forming a first oxide layer from the preliminary oxide layer enclosing a predetermined epitaxial area; (d) depositing an epitaxial layer in the epitaxial area using intrinsic doping; (e) forming a second oxide layer which covers both the epitaxial layer and the first oxide layer, and is merged with the first oxide layer to thus form a contiguous inter-connected inductor oxide layer; (f) forming a metal line according to a planar inductor pattern so as to form a silicon-based inductor structure. The epitaxial layer has a resistivity of at least 2 K ohm-cm. The planar silicon-based inductor improves the Q value by reducing or stopping current losses into the substrate.

  • Patent number: 5917699
    Abstract: A heat-radiating device including a heat-radiator and a heat conductive rod for contacting with a heat source. The heat-radiator is composed of a heat conductive pipe body integrally formed by extrusion, a heat conductive column co-axially extending in the heat conductive pipe body and multiple heat-radiating vanes radially arranged between an outer periphery of the heat conductive column and an inner periphery of the heat conductive pipe body. The heat conductive rod is connected with the heat conductive column, whereby the column absorbs the heat conducted by the heat conductive rod from the heat source and the heat is spread from the center of the heat conductive column. The distance is shortest so that the heat can be quickly and evenly conducted to the respective vanes and the heat conductive pipe body and then quickly dissipated due to natural convection of air or forced convection by a fan.

  • Patent number: 5910193
    Abstract: A brake lever device includes a handle having a lever pivotally coupled to the base. The lever includes a groove and two or more notches communicating with the groove. A cable coupler includes a rod slidably engaged in the groove and to be engaged with either of the notches. A post is rotatably engaged in the lever and has a notch for allowing the rod to be moved to engage with the other notch when the notch is faced toward the notches. The rod may be stably retained in the notches when the notch of the post is faced away from the notches.

  • Patent number: 5903709
    Abstract: Electrode elements directly heat water and with an electric current controller that is controlled by the heated water volume, which structurally enables immediate production of high temperature steam. The innovations of the invention here include: the utilization of an electric current controller than can be set at a certain value so that an electromagnetic water input valve is switched on or off at an appropriate time, which permits the maintaining of a fixed volume of water inside the water container and as such, the water inside the water container is not only prevented from overflowing, but at the same time forms an electric field with the electrode elements and is subsequently directly heated and thereby enables the production of high temperature steam in an extremely short period of time.

  • Patent number: 5894920
    Abstract: A brick-like article feeding mechanism with nearly square travel path and quick returning function includes an eccentric apparatus composed of a slide block and a slide channel and cooperative spur gear and internal gear with a gear ratio of 1:4. In cooperation with synchronously driving sprockets, the pushing arms for feeding the article travel through a nearly square path. One side of the square travel path (loading travel) costs a period of time equal to the sum of the time cost by the other three sides (unloading travel) so as to achieve a quick returning function and synchronous operation.

  • Patent number: 5878367
    Abstract: Traffic is monitored in individual lanes of a roadway as to vehicle count or presence, speed and direction of movement by mounting a microphone array high above the road surface, digitizing the output signals of the microphones, filtering, beamforming and storing the digitized signals to provide separate power histories for separate locations in individual lanes. These power histories are then analyzed to provide vehicle movement data for each lane.

  • Patent number: 5855373
    Abstract: The invention herein relates to kind of improve equilibrium game device, specifically referring to a kind that has a game board with a linear motion slot that is a randomly non-collinear and of a varying width through which the player moves an equilibrium rod. The unique innovation of the invention herein is the attachment of a looped surfacing or a hooked surfacing on the contoured inner surfaces of the linear motion slot and the attachment of a looped surfacing or hooked surfacing to the outer aspect of the equilibrium rod, with the particular surfacing applied to the linear motion slot and on the equilibrium rod being of an opposite nature to produce snagging or frictional resistance upon mutual contact, such that the player is afforded a safe, simple and convenient means of practicing equilibrium by avoiding contact that would, due to engagement of the respective hooked and looped surfaces, prevent continued movement of the equilibrium rod through the linear motion slot.

  • Patent number: 5854011
    Abstract: A composition and method for detecting the presence or amount of yeasts and molds in a test sample is presented. The composition contains a substrate and an inhibitor for an aminopeptidase. The substrate has a signal moiety capable of providing a detectable signal when cleaved by an aminopeptidase in yeasts or molds. The aminopeptidase inhibitor serves to reduce the endogenous aminopeptidase activity in the test sample. The method to detect yeasts or molds in a sample includes inoculating a test sample with the disclosed composition, incubating the sample and observing any detectable signal that indicates the presence of yeasts or molds.
