Abstract: PURPOSE: To form a stationary circulation flow speedily upon resuming the operation, in an apparatus for cycling carrier particles, to which aerobic bacteria are adhered, with air bubbles, by arranging an injection disturber for pulverizing mudd balls.  
     CONSTITUTION: Sewage supplied into a fluid vessel 1 rises with carrier particles 5 through an air lift pipe 8 by aerating from a sparger 6, and then falls down outside the pipe 8 for circulation. Aerobic bacteria breed on the carrier 5 to form a biomembrane adhered thereto, and are cycled to biologically decompose and separate organic substances in the sewage. The disposed sewage containing partially stripped biomembranes overflows into a sedimentation pool 2, and discharged through a disposed water vessel 10. In this case, when the operation is stopped by a service interruption or because of holiday, the carriers 5 are accumulated and formed as bulky mudd balls. Therefore, part of the disposed water from the vessel 10 is mixed with air from an air blower 30 by an ejector 40, and the mixture is injected through an injection disturber 20 at the bottom of the vessel 1.

     PROCESS: An ester compound expressed by formula II[either one of R 1  and R 2  is H, and the other is RCO- (R is H or lower alkyl)]is hydrolyzed to give the compound expressed by formulaI. The hydrolysis is carried out by adding water to the reaction mixture, and heating the mixture at about 50W100°C, or adding a dilute aqueous solution of an alkali, e.g. NaOH, thereto at about room temperature. Alternatively, an organic peracid expressed by the formula RCOOOH is reacted with 3-cyano-propene-1 in the presence of water to afford the compound expressed by formulaI. The latter reaction is carried out in the presence of an organic acid expressed by the formula RCOOH, and the resultant ester expressed by formula II is hydrolyzed in the same way as in the former reaction.

Abstract: PURPOSE: To reduce stress in the transverse direction due to vibration by fixing a shoe receiver on a top face of a foundation fixed on the ground, fixing a shoe on a bottom face of a column which supports a girder, and erecting the column on the foundation in such a manner that it can slide. CONSTITUTION: A foundation 3 made of reinforced concrete is fixed on the ground 10, and a shoe 5 made of metal which is preserved, ceramics or carbon fiber structure is fixed by covering a lower end face of a column 1 made of reinforced concrete or steel structure.
