An optical black pixel region, in which a plurality of optical black pixels for setting a dark-time level are formed, is formed in the pixel area. A barrier layer, which has an impurity concentration that is higher than an impurity concentration of the semiconductor substrate and has a conductivity type that is identical to a conductivity type of the semiconductor substrate, is formed in the optical black pixel region of the semiconductor substrate.

A repetitive burst-mode input signal that has a dark time portion, a preamble portion, and a payload portion is converted into a limited output signal in accordance with a decision threshold level, which is controlled by selectively coupling an averaged value of the burst-mode data amplitude to the decision threshold level. The timing sequence for selectively coupling the averaged signal value is controlled such that the average value of the burst-mode signal acquired during the preamble portion of the burst-mode signal is applied to the decision threshold level during substantially all of the payload portion. The control circuit may incorporate a phase-locked loop, which locks onto the repetitive dark time frequency and in response synthesizes a switchable track enable signal that controls the timing sequence of the decision threshold level. The phase-locked loop can employ all-digital, analog, and / or hybrid digital / analog circuitry.

The invention discloses a method for establishing a syntrichia caninervis mitt. individual plant cloning system through asexual propagation. The method comprises the following steps: a syntrichia caninervis mitt. pure group is selected, a robustly growing plant is selected and the pure group and the plant are washed and sterilized, then sterilized fine-pointed forceps are used to take the stem tips, stems and stem leaf pieces with strong regeneration capabilities of the treated syntrichia caninervis mitt. individual plant, the stem tips, stems and stem leaf pieces are inoculated to a sterilized BBM solid culture medium and then a culture dish is sealed with a parafilm; the culture dish is put in an illuminating incubator for culture under the conditions that the temperature is 25 DEG C, the illumination intensity is 36mu mol.m<-2>.s<-1> and the light / dark time is 14h / 10h, after culture for 2-3 weeks, new branches will appear on the stem tips, spores and leaf blade bases of the mosses through induction; the protonemata will appear on the stem leaf pieces and new branches will appear when the protonemata are developed to a certain stage; and 2 weeks later, the new branches are takenoff, the stem tips and stems of the new branches are re-transferred to a new solid culture medium and repeated transfer and progressive amplification culture are carried out to form the individual plant cloning system.

The invention discloses a mixed-culture and hybridization method for goats.The mixed-culture and hybridization method includes the step that a sheep yard is built on mountain land, Boer goats, Mongolian gazelles and local black goats are mixed and bred for a long time, and includes the balance steps that 1, sheep houses are built, wherein at least one unit colony house is built, and a moving area and a sleeping area are arranged in each unit colony house; 2, ryegrass, pasture, mulberries and sorghum are planted in the moving areas of the colony houses; 3, stocking and confining are combined, in spring and autumn, the goats are let out at twelve, and are taken back at seven, in summer, the goats are sent out at three in the afternoon, and are taken back at the dark time, on the rainy day and in winter, confining is carried out, and confining feed is mainly corn, soybeans and a plurality of crops; 4, 1-2 produced lambs need to be separated, and need to be separated and fed for 1 month-2 months and fed in a grouped mode.According to the mixed-culture and hybridization method, Boer goats, Mongolian gazelles and local black goats are mixed and bred on the mountain land, the goats are acclimatized to allow the habits of the goats to be similar, then high-quality and strong goats are hybridized, high-quality descendant goats are cultured, and the survival rate of the goats is increased.
