摘要:
A process for preparation of a polymeric piezo-electric material and material prepared by said process are described, wherein said process comprises polarizing a polymeric piezo-electric material by a polarization treatment which comprisescooling a vinylidene fluoride-trifluoroethylene copolymer from a temperature higher than the phase transition temperature of said copolymer which exists between room temperature and the melting point of said copolymer, and either maintaining the temperature range at which said copolymer possesses a maximum in dielectric constant occurs, or cooling gradually through said temperature range, while applying an electric field at least within said temperature range.
摘要:
A coating apparatus is disclosed. The apparatus comprises a coating head having a slide face along which a coating liquid flows down and a roll moving a continuous web downwardly. The slide face and the roll define a space for forming a sustained liquid mass therein. The coating head has a bottom face which is provided with a groove in the proximity of and substantially parallelly to the slide face whereby a thin liquid film is formed on the web at high speed.
摘要:
A process for sterilizing a container holding a fluid diet, the container having a long and slender mouth and being filled with the fluid diet and sealed; the process includes the steps of filling the container with the fluid diet in a heated state, sealing the container at the mouth thereof, and thereafter turning the container with its mouth side down to immerse only the mouth and the vicinity thereof in a hot-water bath for a period of time sufficient to achieve sterilization. An apparatus for carrying out the process includes a bucket conveyor, a feed conveyor, a bucket and a bath. The process and apparatus can well sterilize containers holding a fluid diet and having a long and slender mouth. The process and apparatus can well sterilize containers holding a fluid diet and having a long and slender mouth.
