摘要： The process gives highly pure cyclopentadiene and methylcyclopentadiene from a cracked gasoline fraction. The merit of the process is that cyclopentadiene and methylcyclopentadiene are recovered by adding a simple distillation system to a conventional cracked gasoline treating plant without altering the plant and operating conditions thereof. An internal reflux stream is withdrawn from the stripping section of a BTX column of a conventional cracked gasoline treating plant, and is sent to a depolymerization-distillation column operated at a bottom temperature of 160.degree.-230.degree. C. The overhead stream of the column is sent to a cyclopentadiene column operated at a bottom temperature of 160.degree.-230.degree. C. Cyclopentadiene is recovered from the overhead of the column, and the bottom stream is sent to methylcyclopentadiene column operated at a bottom temperature of 170.degree.-210.degree. C. Methylcyclopentadiene is recovered from the overhead of the column.

摘要： The invention concerns an image-capturing apparatus and an imager. The image-capturing apparatus includes the imager in which a plurality of circuit cells are two-dimensionally aligned, and an electronic charge, photo-electronically converted from a received light and stored in each circuit cell, can be discharged from an arbitral circuit cell. The imager includes first group circuit cells to generate electronic charges corresponding to the pixels of the image including a subject, and second group circuit cells to generate electronic charges corresponding to an amount of light coming from the subject, the electronic charges further being converted to a detected value. In the imager, at least one of two operations of halting a generating-action of the electronic charges in the first group circuit cells and discharging the electronic charges from the first group circuit cells is performed, when the detected value exceeds a threshold value.
