    摘要： This invention provides a process for producing a 5-hydroxy-3-oxopentanoic acid, a useful pharmaceutical intermediate, easily from a readily available, inexpensive starting material without using any extraordinary production equipment such as a very-low-temperature reactor. Thus, this invention provides a process for producing a 5-hydroxy-3-oxopentanoic acid which comprises permitting a lithium amide to act upon a mixture of an acetic acid ester and a 3-hydroxypropionic acid derivative at not below −20° C. Further, this invention also provides a process for producing a 5-hydroxy-3-oxopentanoic acid which comprises treating a mixture of an acetic acid ester and a 3-hydroxypropionic acid derivative with a Grignard reagent to prepare a mixture of a compound and an acetic acid ester of the above formula (I), and permitting a lithium amide to act upon the mixture at a temperature not below −20° C.

    摘要： This invention relates to a gas refining system wherein a high-temperature and high-pressure reducing gas is introduced into a fixed-bed desulfurizer packed with an adsorbent by which sulfur compounds contained in the high-temperature and high-pressure reducing gas are adsorbed and removed in the form of a sulfide, and the adsorbent having the sulfide adsorbed thereon is regenerated by roasting it with a regenerating gas containing oxygen, characterized in that the gas refining system is equipped with oxygen concentration control means for controlling the oxygen concentration in the regenerating gas introduced into the desulfurizer so as to keep the internal temperature of the desulfurizer during the regeneration reaction within the allowable temperature range of the adsorbent. This invention includes an embodiment in which the exhaust gas obtained after the regeneration reaction gas is brought into contact with a calcium compound-containing slurry to recover gypsum is recycled to the desulfurizer for use as the regenerating gas for the adsorbent. Thus, the adverse effect of the heat of regeneration reaction on the adsorbent used in the fixed-bed desulfurizer can be avoided positively and easily.

    摘要： An integration-proportional controller in a servo-control system comprises in one aspect, an integrator for integrating a deviation of an input speed reference signal from a feedback signal fed back from an object to be controlled, and a proportional amplifier connected with the integrator for amplifying the feedback signal, the integrator including a clamping function in which an output value therefrom and an initial value for the next successive integration are changed, when the output value as a result of integration of the deviation is out of a predetermined proper output region, to the nearest boundary of the predetermined region value. In another aspaect, a saturable integrator is provided for integrating a deviation of an input speed reference signal from a feedback signal fed back from an object to be controlled, a proportional amplifier is connected with the saturable integrator for amplifying the feedback signal, and a deviation clamping device is connected with the saturable integrator for limiting the upper and lower values of the deviation.
