    摘要： Disclosed is a composition for forming a dielectric, which is applied to an embedded capacitor with a high dielectric constant, a capacitor produced using the composition, and a PCB provided with the capacitor. The composition includes 40 to 99 vol % of thermoplastic or thermosetting resin, and 1 to 60 vol % of semiconductive filler. Alternatively, the composition includes 40 to 95 vol % of thermoplastic or thermosetting resin, and 5 to 60 vol % of semiconductive ferroelectric substance. Furthermore, the present invention provides the capacitor, produced using the composition, and the PCB provided with the capacitor. Therefore, the dielectric, which is produced using the composition including the semiconductive filler or semiconductive ferroelectric substance, is advantageous in that the dielectric constant is high and a dielectric loss is low. The dielectric is usefully applied to produce an embedded capacitor with the high dielectric constant and the PCB provided with the embedded capacitor.

    摘要： A light guide plate and a liquid crystal display device having the same. The light guide plate is disposed upstream of a liquid crystal panel to refract light supplied through an edge thereof, toward the liquid crystal panel. In the light guide plate, a plate body is disposed at a side of a light source for supplying light when a supply voltage is applied. A plurality of pyramidal diffusing elements are arrayed in a predetermined pattern on a surface of the plate body. Each of the diffusing elements is rotated clockwise or counterclockwise about an axis extending through a vertex of the diffusing element perpendicularly to the surface of the plate body so that an edge of the diffusing element facing a reference line connecting a central point of the light source to a central point of the plate body is angled 10° to 35° about the reference line.

    摘要： Conventional rechargeable battery packs for portable electronic products possess charging terminals for connecting the battery packs to charging devices. When a portable electronic product is in use, there is a potential for short circuiting the battery pack by connecting one or more objects to the exposed charging terminals. This invention provides a battery pack for a portable electronic product with a short circuit prevention function where the charging terminal is exposed only when plugged into a charging device. By protecting the charging terminals, the invention prevents a short circuit from occurring during normal operation of the portable electronic product. The battery pack with a short circuit prevention function comprises a spring-loaded cover that is adapted to travel over the main body of the battery pack to alternately cover and expose the charging terminal.
