Abstract: An anchor dock includes an anchor body, an adsorption portion and a bracing rack. The anchor body has a lower shell and an upper shell. The lower shell has a conical side surface formed at a sloped angle. The upper shell is located on an upper surface of the lower shell. The adsorption portion is located below the anchor body. The bracing rack is formed in a U-shape and surrounds the upper shell and has two ends hinged on the anchor body.

Abstract: A fastening holding rack includes a holding dock, a holding device and a fastening apparatus. The holding device has a holding bracket and a fastened member. The fastening apparatus includes a collet and a sleeve. The collet has a bottom and a plurality of jutting plates. The collet is mounted onto the holding dock to hold the fastened member. The jutting plates are located longitudinally on the bottom in a protrusive manner. Each of the jutting plates has an outer surface on which a portion is extended outwards greater than another portion. The collet is encased in the sleeve. The sleeve has a tubular wall which has a plurality of segments corresponding to the jutting plates. Each segment has an inner surface on which a portion is extended inwards greater than another portion. When the greater extended inward portion of the tubular wall is in contact with the greater extended outwards portion of the jutting plate, the jutting plate is tilted inwards to press the fastened member.

Abstract: A composite shadow ring that is constructed of an upper ring and a lower ring assembled together by a plurality of dowel pins and a method for using the ring. The upper ring and the lower ring each has a predetermined outside diameter that is substantially the same, a planar top surface and a planer bottom surface parallel to the planar top surface. Each of the planar bottom surface of the upper ring and the planar top surface of the lower ring has at least two blind holes formed therein. A plurality of dowel pins are used to frictionally engage the at least two blind holes in the upper ring and the at least two blind holes in the lower ring.

Abstract: An adjustable holding frame mainly includes a first bar, a second bar and an adjusting means. The second bar has one end fastened to a lump element which is pivotally located in the adjusting means. The adjusting means is mounted onto the first bar and has a helical structure to adjust the position of a seat in the adjusting means. Thereby releasing or fastening of the lump element of the second bar can be controlled to adjust the posture condition of the holding frame.

Abstract: An anchor structure for electronic devices includes a plurality of bars that are pivotally coupled through a hinged means. At least one of the bars has a housing space formed in a portion of the interior to allow the bars to be swivelable relative to one another. The anchor structure further has a fastening means which has a handle with a bottom end located in the housing space and hinged on a corresponding bar. The hinged portion on the bottom end of the handle runs through the bar and is fastened to a cam. The housing space also holds a slidable brake element corresponding to the cam and a spring to keep the brake element in contact tightly with the cam so that turning of the cam can selectively move the brake element to a position to escape the axle or to another position to form a tight contact with an axle.

Abstract: An anchor rack having a coupling pawl has a plurality of slots on the coupling pawl and a conical outer surface. A sleeve and an elastic element are provided to be coupled with the coupling pawl to form interactions with one another. The coupling pawl has an opening which can be extended or shrunk. Hence a housing space formed in the coupling pawl also can be extended or shrunk. Thereby a tight coupling with a holding rack can be easily formed.

Abstract: A system in a motor vehicle having a hazard warning light and a manual control switch, an improvement consisting of electronic circuitry which causes the hazard warning lights to automatically activate under circumstances of an engine stall and to remain activated until manually reset by the vehicle operator, said system comprising: a detecting means (4) for detecting an engine stall while the ignition switch is switched on; a signal generating means (6) responsive to said detecting means (4) for generating a flashing signal upon signaling by the detecting means (4) of an engine stall; and a manual control means (12) connected to the hazard warning light for manually activating and deactivating the hazard warning light.
