A support structure of a portable keyboard includes two front support and a rear support. The front supports and the rear support can rotate to two predetermined angles respectively to form a confine within which a portable computer may be placed and supported. The rear support supports a backside of the portable computer, and the front supports push against a lower edge of the portable computer. Furthermore, both the front supports and the rear support can be closed onto an upper surface of the portable keyboard.

An assembling structure for the door lock includes a lever, a lock core unit, an axial tube and an adapter. The lever has a compartment and an engaging member formed therein. The axial tube provides with a longitudinal slot and a transverse-retaining recession formed therein. The adapter also correspondingly provides with a positioning member. Firstly, when the adapter and the axial tube are assembled, the positioning member of the adapter is engaged with the traverse-retaining recession of the axial tube via the longitudinal slot so that the axial tube and the adapter constitute a combination unit. Secondly, assembling the lever and the combination unit, the engaging member of the lever is engaged with the longitudinal slot of the axial tube. Due to obstruction of the engaging member of the lever in the longitudinal slot, the positioning member of the adapter is confined and unable to return to the longitudinal slot.

A door lock includes a cylinder with a core installed in a door A flat finger is connected with the core. A latch is movably provided in a latch hole of the door and the flat finger extends through the latch. An inner cover is provided at an interior surface of the door opposite to the cylinder and has a plurality of sink holes defined therethrough for a plurality of first screws extending through the sink holes and engaged in the threaded holes. An outer cover is provided outside the inner cover to conceal the inner cover. A knob is provided outside the outer cover and has a hollow shaft extending through the outer cover and the inner cover and connected with the finger. Whereby, when the knob is turned, the latch can be extended or retracted to lock/unlock the door.

A lock structure for bathroom use comprises an outer rose, an inner rose, an outer unlatching mechanism mounted to the outer rose, and an inner unlatching mechanism mounted to the inner rose. The inner unlatching mechanism includes a turnable inner unlatching rod on which a locking wheel is mounted to turn therewith. The locking wheel includes an engaging block for selectively engaging with a first engaging notch and a second engaging notch in a fixing member securely mounted in the inner rose. When the engaging block is engaged in the second engaging notch of the fixing member, the locking wheel is engaged in a notch of a follower wheel mounted on an inner spindle. The follower wheel can be turned when the inner handle is turned such that rotation of the follower wheel returns the locking wheel, thereby achieving the unlatching operation.

A tracking error (TE) signal polarity determining method, comprising: (a) obtaining a wobble related signal and a TE signal from an optical pick-up unit accessing an optical disc; (b) determining an accessing direction; and (c) determining if an original polarity of the TE signal from the optical disc should be changed or not according to the relation between the wobble related signal and the accessing direction.
摘要:
A detector is scanned across an optical storage medium having groove tracks and land tracks, each track having a wobble structure, to detect light reflected from the optical storage medium. A wobble signal and a tracking error signal are generated based on an output of the detector, and the wobble signal is sampled according to the tracking error signal. A determination about whether the detector is at the groove track or the land track is made based on the tracking error signal and a comparison of sampled values of the wobble signal.

The invention provides a driving circuit for driving a laser diode of a pickup head. In one embodiment, the driving circuit comprises an automatic power control (APC) module, a clamp value determination unit, and a clamp circuit. The automatic power control module generates at least one power control signal. The clamp value determination unit dynamically determines at least one clamp value corresponding to the power control signal when the pickup head accesses an optical storage medium. The clamp circuit clamps the power control signal according to the clamp value to obtain a clamped power control signal. A driving signal for driving the laser diode can then be generated according to at least the clamped power control signal.

The invention provides a method for controlling spherical aberration correction for an optical disk drive. First, a collimator lens is moved to a first target position for spherical aberration correction. A driving time of motion of the collimator lens is then calculated. A prohibiting time is then determined according to the driving time. The collimator lens is then prevented from moving until the prohibiting time elapses.
