A method of accessing an optical disc is disclosed. The method includes: enabling a focus servo control without enabling a tracking servo control, and then moving an optical pick-up unit in a radial direction of the optical disc; obtaining at least a first reference signal and a second reference signal according to a laser beam reflected from the optical disc when the optical pick-up unit is moving in the radial direction; and monitoring at least the first reference signal and the second reference signal to identify a boundary of a predetermined data area on the optical disc.

A latch driving unit is assembled in an exterior knob assembly of a door lock. The latch driving unit includes a pin, a resilient member, a locking disk, a rotatable disk, a torsion spring, a cap and a strip. The strip removably extends through the cap, torsion spring, rotatable disk, locking disk, resilient member and the pin. If the strip is bent with an incorrect length, it can be removed from the latch driving unit and replaced with an intact strip. Thus, the exterior knob assembly is still useful after replacing the strip, and waste is avoided.

A dynamic compensation device for radio frequency ripple signals of an optical storage system is disclosed. The device is composed of a radio frequency ripple signal process circuit, a radio frequency signal process circuit, a radio frequency signal peak detector, a first analog to digital converter, a second analog to digital converter, a defect detector, and a fingerprint detector. The drop-out of the central level of the radio frequency ripple signal is eliminated, and the track cross waveform is prevented from being damaged.

A method for forming a tungsten layer on a substrate surface is provided. In one aspect, the method includes positioning the substrate surface in a processing chamber and exposing the substrate surface to a soak. A nucleation layer is then deposited on the substrate surface in the same processing chamber by alternately pulsing a tungsten-containing compound and a reducing gas selected from a group consisting of silane, disilane, dichlorosilane and derivatives thereof. A tungsten bulk layer may then be deposited on the nucleation layer using cyclical deposition, chemical vapor deposition, or physical vapor deposition techniques.

A rotatable display mounting arrangement is disclosed to include a base having a first pivot structure, an open frame, the open frame having a second pivot structure pivotally coupled to the first pivot structure of the base and a second pivoting means symmetrically disposed at top and bottom frame bars thereof, and a display horizontally rotatably mounted within the open frame, the display having a first pivoting means symmetrically disposed at the top and bottom sides and respectively pivoted to the second pivoting means of the open frame, the first pivoting means having wire holes for the passing of the electric circuit wire of an antenna embedded in the top frame bar of the open frame and the electric circuit wire of the base to the display.
摘要:
A lid device of a double-sided auxiliary lock comprises an inner annular wall, an outer annular wall and a plurality of engaging portions. The engaging portions are equi-spaced on the outer annular wall. A double-sided auxiliary lock has an interior auxiliary lock assembly and a plurality of positioning elements. The interior auxiliary lock assembly has a locking coreprovided with an outer annular recess, a plurality of via holes, an inner annular groove, and a keyway. The inner annular groove is communicated to the keyway. The inner annular wall is corresponding to the inner annular groove of the locking core. The engaging portions are engaged to the outer annular recess of the locking core. Thereby, the lid can cover the positioning elements. In assembly, the lid has at least one engaging portion to be positioned correspondingly to the keyway. Thereby, detaching the cover, the disengagement of the engaging portions from the outer annular recess can be operate through the keyway.
