Abstract: A large number of display components are arranged and fixed, for example, in a matrix configuration on a first principal surface of a large optical guide plate to construct a main display device body. A substance having a light-transmitting property adjusted for its refractive index is allowed to intervene at least between the large optical guide plate and the display components. The refractive index of the substance is preferably similar to the refractive index of the large optical guide plate as closely as possible. As for the light-transmitting property of the substrate, it is preferable that the transmittance is not less than 50% for the perpendicular incident light at the wavelength in the visible light region, and it is more preferable that the transmittance is not less than 70%, in order to successfully introduce the light into the display component and suppress the electric power consumption.

Abstract: In a data receiver, pulse edges are sequentially detected from the pulse string. If a pulse which has a width equal to two cycles of the reference clock signals is detected, bit data ‘1’ is restored. If two consecutive pulses each of which has a width equal to one cycle are detected, bit data ‘0’ is restored. If a pulse width between two consecutive pulse edges is not equal to one cycle or two cycles, it is presumed that a pulse edge of an erroneous pulse is detected. If the pulse width between the pulse edge, which is presumed to correspond to the erroneous pulse, and the next pulse edge is equal to or shorter than a predetermined threshold Th, the pulse edge and the next pulse edge is invalidated.

Abstract: A chip peeling apparatus has a plurality of protrusions which include first protrusions and second protrusions lower than the first protrusions. A vacuum pump communicates through holes with grooves defined between adjacent ones of the protrusions. A UV sheet is attached to chips, and the chips are supported in the vicinity of their corners by the tops of the first protrusions. When the vacuum pump is actuated, the chips and streets disposed between the chips are lowered, and the chips are curved and supported in abutment against the tops of the second protrusions. Each of the chips is gradually peeled off the UV sheet under a force tending to recover the original shape of the curved sheet. The chip peeling apparatus is effective in preventing the chips from being damaged and positionally deviated when the chips are attracted and carried.
