摘要:
In an adjustable bed, a bending angle of a lift arm is precisely adjusted according to generated signals corresponding to a wheel rotated by a motor of the adjustable bed or according to a current state related to the wheel. The signals are generated according to whether light is obstructed by gratings, according to whether a magnetic force is detected, or according to a change of a magnetic field. The current state is current resistance of a variable resistor disposed near the wheel.

A liquid crystal display (LCD) driver has the characteristic that using a voltage-switching control circuit to receive the liquid crystal positive voltage and the segment positive voltage generated by the driving voltage generating circuit. The voltage-switching control circuit respectively switches the liquid crystal positive voltage and the liquid crystal negative voltage to input to the common driver in different frame stages such that only one of the liquid crystal positive voltage and the liquid crystal negative voltage exists at the same time. Therefore, for the choice of the semiconductor manufacturing process for the LCD driver, the process with only half of the voltage-resistant can be chosen according to the original design of the circuit, and the supplying for the voltage needed by the segment driver and the common driver is unchanged.

A protective cover plate mainly comprises a substrate, a printing layer, an ultraviolet layer and an adhesive layer, wherein the printing layer is disposed at a side surface of the substrate. The printing layer is formed with at least a pattern. The pattern protrudes the substrate to form a segmental difference surface. The ultraviolet layer is disposed to another side surface of the printing layer relative to the substrate, and the ultraviolet layer is disposed with at least a filling portion. The filling portion can be relatively located near the pattern to fill the segmental difference surface of the pattern to flat the surface. A side of the ultraviolet layer is disposed with the adhesive layer. The plate can be adhered to the article by utilizing the adhesive layer. The protective cover plate does not only have flat appearance but also achieves dustproof and dirt prevention efficacies.

摘要:
The present invention is to provide a dissipator mounting apparatus having a metal plate and a metal snap ring, where the two sides of the metal plate stretch upward and form an elastic tilt angle, and on one end of the metal plate bends downward and forms an opening to be firmly received in the barb of the ZIF socket, while the other end of the metal plate forms another hole for holding the snap ring whose rods stretch horizontally inward from the gap. Thus the CPU and the dissipator board can be tightly combined together with the help of the mounting apparatus.
