An integrated receiver with channel selection and image rejection substantially implemented on a single CMOS integrated circuit is described. A particularly preferred embodiment is wherein the separation medium is retained by a photopolymer frit, which can be reliably and reproducibly generated with controlled porosity. The lighting member shines light to the gem stone which then refracts or reflects light from various angles to produce dazzling light. When the sensed output current is determined to have exceeded a predetermined threshold, the output of the power adapter may be switched from the first to the second tap by uncoupling the first tap from the output of the power adapter and coupling the second tap to the output of the power adapter. Estimated value of assembling-related fraction defective is arithmetically determined with high accuracy by executing an assembling-related fraction defective value estimating program on the basis of the data as inputted.
