摘要： A linear vibrator is disclosed. The linear vibrator includes a base, a coil unit, which is coupled to the base, a magnet, which is coupled to the coil unit such that the magnet can move relatively, and a plurality of leaf springs, which are interposed between the magnet and the base. Here, the plurality of leaf springs face one another and are coupled to one another Thus, the linear vibrator can increase the range of vibration displacement in a structure and increase the amount of vibration in the linear vibrator. Also, even though the linear vibrator becomes thinner, the range of displacement can be increased because the weight is vibrated horizontally.

摘要： Provided is a method for preparing a compound semiconductor substrate. The method includes coating a plurality of spherical balls on a substrate, growing a compound semiconductor epitaxial layer on the substrate coated with the spherical balls while allowing voids to be formed under the spherical balls, and cooling the substrate on which the compound semiconductor epitaxial layer is grown so that the substrate and the compound semiconductor epitaxial layer are self-separated along the voids. The spherical ball treatment can reduce dislocation generations. In addition, because the substrate and the compound semiconductor epitaxial layer are separated through the self-separation, there is no need for laser lift-off process.

摘要： A gray-scale representation method for a plasma display panel, which method includes arranging, in time sequence, a plurality of subfields each having a brightness weight and achieving gray-scale representation by a combination of the subfields, each subfield including an address period and a sustain period. In the gray-scale representation method, the number of sustain pulses for each subfield is determined so that a light generated from the difference of the number of sustain pulses between two adjacent gray scales can be greater than a light discharged in the address period, when the number of subfields for the higher one of the two adjacent gray scales is less than that for the lower one. The reversion of gray scales that occurs when the address light is increased as high as the sustain light can be eliminated to achieve correct gray-scale representation. A smoother gray-scale representation can be achieved with reduced power consumption by adjusting the difference of the number of sustain pulses between the two adjacent gray scales in consideration of the address light.
