Abstract: A rotating mechanism for an LCD monitor having a monitor and a supporting structure. The rotating mechanism comprises a protruding sleeve, a supporting body, a shaft sleeve, a sleeve, a first screwing element and a second screwing element. The protruding sleeve has a fitting hole and is disposed on the back of the monitor. The supporting body has a bending element. The shaft sleeve is fitted between the protruding sleeve and the bending element of the supporting body. The sleeve is fitted in the fitting hole of the protruding sleeve. The first screwing element is threaded into one end of the shaft sleeve from the sleeve. The second screwing element is threaded into the other end of the shaft sleeve from the bending element. Thus, the tightness of the rotating mechanism of the invention can be adjusted by way of the first screwing element.

Abstract: A double-side automatic feeding apparatus comprises a paper feeder, a paper outlet opposite to the paper feeder, a scanning region having a document traveling path bridging the paper feeder and the paper outlet, a plurality of rollers being arranged in the scanning region to convey a document to be scanned from the paper feeder to the paper outlet, and a paper flipping unit arranged in the document traveling path. The paper flipping unit can be selectively switched position thereof and used to flip the document during the document traveling path. By the invention, the document can be scanned on both sides thereof without cumbersome reverse movement. The document can be automatically aligned by the weight per se and the operations of paper placement and removal can be simplified.

Abstract: A double-side automatic feeding apparatus comprises a paper feeder, a first paper holder, a second paper holder, a document traveling path and a paper flipping unit. The paper feeder, the first paper holder and the second paper holder are arranged apart in longitudinal direction. The document traveling path is of E shape and connected to the paper feeder, the first paper holder and the second paper holder. The document traveling path is provided with a plurality of rollers to move a document from the paper feeder to one of the first paper holder and the second paper holder. The paper flipping unit is arranged in the document traveling path and can be trigger to flip the document during the document traveling path. By the double-side automatic feeding apparatus, a document can be selectively printed or scanned on single- or double-side thereof at user's disposal.

Abstract: A manufacturing method for white light source utilizes an ultraviolet light source and suitable phosphors. One of the phosphors is directly excited by the ultraviolet light source and generates a radiation with longer wavelength. Other phosphors are excited by the radiation with longer wavelength and generate radiation with much longer wavelength. The lights generated by those phosphors are mixed to form a white light.

Abstract: An apparatus for inputting opening and closing parentheses simultaneously by a single keystroke and method for the same are proposed. The keyboard is augmented with a parenthesis key. The opening and closing parentheses are simultaneously input by pressing the parenthesis key, wherein the key codes for opening parenthesis, closing parenthesis and cursor right are successively generated. Therefore, opening and closing parentheses are simultaneously input and cursor is placed between the opening and closing parentheses to facilitate typing.

Abstract: A photo interrupter with dual-direction detection ability comprises a main body, a pointer, a first spring and a second spring. The main body has retainers for pivotally clamping the pointer such that the pointer can rotate both in counterclockwise and clockwise directions. The pointer has a baffle in the recess to block a light from a light emitter to a light receiver and a pendulum end to sense the presence of paper. The first spring provides a counterclockwise restoring force for the pointer and the second spring provide a clockwise restoring force for the pointer such that the photo interrupter can sense paper fed in both directions.

Abstract: A vibration-reduced disk drive system is provided. The disk drive system comprises a reading device having a mechanism for high speed rotation of a data storage disk, and a weight body disposed adjacent to the reading device. The disk drive system also comprises at least one hanging device formed of a metallic material that joins the reading device and the weight body for transferring vibration therebetween. The disk drive system thus effects vibration dampening for the reading device and its housing, so as to preserve the stability of access to the data stored on the given data storage disk.

Abstract: A tray for loading and ejecting a disk into and out of a disk drive includes a step wall structure that defines a positioning area for receiving the disk and a clamping arrangement used to hold the disk during loading and unloading when the disk drive is in a vertical position. The clamping arrangement is made up of a clamping device biased by an elastic member so as to apply a radial force to the disk and urge the disk against the step wall. The clamping device includes a flexible mortise slot that engages a pillar extending from the tray to latch the clamping device and thereby disable the clamping device when the disk drive is horizontally positioned.

Abstract: An automatic video display testing and adjusting system mounted to a CRT video display of a monitor or a TV set is made up a transparent mask, a main circuit board, a computer system which is connected to the main circuit board by a cable, a plurality of adjustable detecting sensor mounting members each having a detecting sensor engaged therewith. The detecting sensors are electrically connected to the main circuit board by wires so that the detected results are able to be fed back to the computer system for analysis and comparison by way of a main computer program. The main circuit board uses interfaces to permit the computer system to communicate with and have control over a tested monitor whereby the main computer program can perform all analytic comparison with set standards and make adjustment automatically on functional discrepancies of the display of a monitor or a TV set.
