  • Linear actuator
    Patent number: 7752932
    Abstract: A linear actuator is provided with an outer tube, an intermediate tube and an inner tube, and the tubes are all polygonal in cross section and are mounted orderly. The outer tube is disposed at the bottom thereof with a push device which has a screw and a nut that are screwed with each other. The nut is engaged in the intermediate tube and is linked to move axially by the screw. The intermediate tube can be movably equipped with a pulling member, and the pulling member can link the inner tube to synchronously move in the axial direction. By such arrangements, the linear actuator allows the respective tubes to extend and retract axially relative to one another while preventing them from moving relative to one another in radial direction, thus achieving the stable and smooth axial movement.

  • Patrol system and patrol method thereof
    Patent number: 7750800
    Abstract: A patrol system comprises: a computer, a receiving and sending communication device, and a plurality of signal elements. The computer and the receiving and sending communication device are wirelessly connected to each other. The receiving and sending communication device serves to sense the signal elements. The signal elements are disposed at designated patrol locations. When a patrolman with a receiving and sending communication device arrives at a designated patrol location and gives feedback to the computer, the computer will determine next patrol location to be patrolled and inform the patrolman. And thus the patrol route of each patrolman is determined randomly by the computer, so that the thief doesn't know the patrol route. Further, even the patrolman doesn't know the next patrol location to be patrolled, thus preventing the patrolman from colluding with the thief and betraying the patrol route.

  • Optical lens system for taking image
    Patent number: 7738186
    Abstract: An optical lens system for taking image comprises, in order from the object side to the image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power having a concave image-side surface and at least one aspheric surface; a meniscus third lens element with negative refractive power having a convex image-side surface; and a fourth lens element with negative refractive power having a convex object-side surface and an aspheric image-side surface. The above configurations and arrangements of the lens elements can effectively reduce the size of the optical system while improving its resolution.

  • Positioning device for chair
    Patent number: 7735925
    Abstract: A positioning device includes a clamping seat having first and second clamping members with clamping portions mounted around a fixed rod of a chair having an inclinable seat to which the first clamping member is fixed. An adjusting rod includes a coupling seat having a positioning groove with a low-profile section and a high-profile section. A positioning block is mounted to the second clamping member and includes a protrusion received in the positioning groove. The protrusion is engagable with one of the low-profile section and the high-profile section, so that the clamping portions can be clamp on or disengage from the fixed rod, allowing controlling of movement of the clamping seat along the fixed rod. The first clamping member includes a sidewall having a hole slideably receiving the fixed rod and in slight tight coupling with the fixed rod.

  • Positioning device for chair
    Patent number: 7735924
    Abstract: A positioning device includes a clamping seat having two clamping members having clamping portions mounted around a fixed rod of a chair having an inclinable seat to which one of the clamping members is fixed. An adjusting rod includes a coupling seat and a handle fixed to the coupling seat. The coupling seat includes a positioning groove having a low-profile section and a high-profile section. A positioning block is mounted to the other clamping member and includes a protrusion received in the positioning groove. When the protrusion is engaged with the low-profile section, the clamping portions are not clamped on the fixed rod, allowing movement of the clamping seat along the fixed rod. When the handle is moved to a clamping position, the protrusion is engaged with the high-profile section, the clamping portions are clamped on the fixed rod, not allowing movement of the clamping seat along the fixed rod.

  • Beam imprinting disk
    Patent number: 7728865
    Abstract: A beam imprinting disk which is provided with a supporting layer, a photosensitive printing layer is formed on the supporting layer, and a paint printing layer is formed on the photosensitive printing layer. One surface of the disk is a data-rewriting surface for writing data, and the other surface of the disk is a label predetermined surface for setting patterns and words. The photosensitive printing layer is disposed on the label predetermined surface of the disk, the paint printing layer is partially disposed on the photosensitive printing layer, so that the user can simultaneously see the photosensitive printing layer and the paint printing layer from the label predetermined surface. By such arrangements, the disk is applicable to the ink jet printer or the beam imprinting optical disk drive, so that the beam imprinting disk has a wide range of application and can meet different user's requirements.
