摘要:
In a backlight apparatus used in an LCD, in which upper and lower reflective plates are installed under upper and lower transparent plates, respectively. The lower transparent plates and the lower reflective plates introduce light generated by lower light sources in upward directions and the upper transparent plate and the upper reflective plates introduce light generated by an upper light source into those areas, which are not lighted by the lower light sources. This can prevent the formation of dark areas above the lower light sources thereby enhancing the overall uniformity of light.

A document is classified into at least one document class by selecting terms for use in the classification from among terms that occur in the document. A similarity between the input document and each class is calculated using information saved for every document class. The calculated similarity to each class is corrected. The class to which the input document belongs is determined in accordance with the corrected similarity to each class.

A wrist rest equipped with a heating device has a base, a heating device and a cushion. The base has a recess and a chamber. The heating device is mounted in and on the base and has a controller, a heating element, a switch and a power source. The controller is mounted in the chamber and controls operation of the heating device. The heating element is mounted in the recess and connected electrically to the controller. The switch is connected electrically to the controller to turn the heating element on and off. The power source is connected electrically to the controller to supply electricity to the heating device. The cushion is mounted in the recess above the heating element and is heated by heat from the heating element to improve the blood circulation in the mouse user's wrist area while a user operates the computer mouse.

A heat sink structure comprises: a heat conducting base being provided thereon with a plurality of heat sinking fins arranged longitudinally and transversely to mutually cross each other; with the help of the blowing air blown by an above installed fan, the heat sink can make a fast exchange of the cool air and hot air in the interspace among the heat sinking fins to help dissipate the heat generated by a CPU to the ambient to achieve the fast heat sinking effect. The structure is applied to a heat sink for a computer, an electronic instrument or some other heat generating electric component.

A fastener element includes a fastener body and a locking part. The body includes a shank having two outer webs interconnected by a transverse web. The outer webs have projections including upper and lower ramp surfaces. The locking part includes an aperture having first and second pairs of opposing edges, and L-shaped holding portions each having a first web portion linked to one of the first opposing edges, and a second web portion extending into the aperture. When the outer webs are introduced into slots between the second opposing edges and the holding portions, the lower ramp surfaces move the holding portions away from each other and the second web portions engage the upper ramp surfaces from above. If the shank is introduced in a fastening hole of a support part while the locking part engages the support part, the holding portions are further pivoted away from each other and the second web portions grip the edge of the fastening hole.

Disclosed are a chip scale package and a method of fabricating the chip scale package. The chip scale package comprises conductive layers with a designated depth formed on an upper and a lower surfaces of a chip, and electrode surfaces formed on the same side surfaces of the conductive layers, which are connected to corresponding connection pads of a printed circuit board. The chip scale package is miniaturized in the whole package size. Further, the method of fabricating the chip scale package does not require a wire-bonding step or a via hole forming step, thereby simplifying the fabrication process of the chip scale package and improving the reliability of the chip scale package.

A peeling device 11 includes an adsorber 15 having an adsorbing face 20A that adsorbs and retains a wafer W, and a peeling element 17 that holds a protective sheet H stuck to the wafer W, and peels off the protective sheet H from the wafer W through moving relatively to the adsorber 15. The adsorber 15 and the peeling element 17 are arranged so as to peel off the protective sheet H from the wafer W intermittently through moving relatively to each other while a peeling operation and a counter-peeling operation are performed alternately.
