摘要:
It is an object of the present invention to provide a method for synthesizing β-lactams and a method for manufacturing β-lactams in water of high-temperature and under high-pressure, and the present invention relates to a β-lactam synthesis method which is characterized in that β-lactams are synthesized by reacting β-amino acids in water at high-temperature and under high-pressure, this method being further characterized in that β-lactams are synthesized at a high speed by cyclizing β-amino acids in water at high-temperature and under high-pressure in which the temperature range is 200° C. or higher and the pressure range is 10 MPa or greater, and the present invention also relates to a method for manufacturing β-lactams which is characterized in that β-lactams are synthesized by reacting β-amino acids in water at high-temperature and under high-pressure, and are then separated and purified using a column separation medium.

A gas separation and recovery apparatus that separates and recovers nitrogen oxides from a gas mixture includes: a liquid storing portion that stores a liquid, the liquid absorbing the nitrogen oxides; a gas-liquid contacting portion in which the liquid and the gas mixture contact with each other; and a liquid recovering portion that recovers the liquid after the liquid contacts the gas mixture. The liquid is an ionic liquid that chemically absorbs the nitrogen oxides.

It is an object of the invention to ensure the same precision as a focus adjustment based on MTF, perform an evaluation of focus adjustment on an entire image pickup surface, and reduce the size of an apparatus for performing the focus adjustment. The focus adjusting apparatus comprises a laser beam emitting section, a beam spot area measuring section, and a lens unit adjusting section. The laser beam emitting section emits a collimated laser beam to the center of the lens unit and converge the same near the center of the image pickup surface, emits a plurality of collimated laser beams at inclined angles to the central portion of the lens unit and converge them near the edges of the image pickup surface. The beam spot area measuring section measures the areas of a plurality of beam spots formed on the image pickup surface upon converging the collimated laser beams, by image-processing an output of the image pickup element. The lens unit adjusting section is equipped with a mechanism capable of adjusting the distance and/or posture of the lens unit with respect to the image pickup surface.
