Abstract: A method for manufacturing frozen noodles including a step of subjecting raw noodles or dried noodles manufactured by an ordinary method to boiling treatment to produce boiled noodles containing moisture less than moisture of the noodles after cooking, a step of applying water to surfaces of the boiled noodles by sprinkling or dipping, a step of filling a freezing container with the boiled noodles having water applied to the surfaces and an ice lump containing frozen water, and a step of subjecting the boiled noodles to freezing treatment, in which the freezing treatment is started within 120 seconds from an end of the boiling treatment.

Abstract: The disclosure is a cold storage material containing: a cold storage material main agent formed from water and a melting point adjuster; and a freezing point adjuster. The melting point adjuster includes a plurality of types of inorganic salts and an organic compound. Anions of the plurality of types of inorganic salts are all chlorine, and cations of the plurality of types of inorganic salts include at least sodium. The freezing point adjuster is a salt having a functional group that is identical to a cation included in any of the plurality of types of inorganic salts, and the salt has a temperature dependence of saturated solubility in pure water that decreases by 30% or more at a water temperature from 20° C. to 0° C.

Abstract: A composite insulator includes a hollow and tapered core portion composed of fiber-reinforced plastics, and a sheath and sheds composed of an insulating polymeric material integrally molded on the outer surface of the core portion. The core portions of composite insulators for a plurality of voltage classes are formed by using a mandrel assembly in which a plurality of mandrel members are combined. The so-prepared core portion is placed within a mold unit in accordance with the voltage class of the composite insulator to be manufactured, and the insulating polymeric material is poured into the mold cavity to integrally mold the sheath and the sheds.

Abstract: A composite insulator-producing lateral type molding apparatus includes a mold body constituted by a first molding unit and a second molding unit, each of said first and second molding units being provided, at an inner peripheral face, with recesses for the formation of a housing constituted by a plurality of shed portions and a axial portion connecting these shed portions, means for opening or tightening the first molding unit and the second molding unit, a pouring passage for pouring a housing-forming material into said recesses, and housing-forming material escape holes. A core member of the insulator is placed between the first and second molding units, the first and second molds are tightened, and the housing-forming material is poured into said recesses to form the housing. The first molding unit and the second molding unit extend laterally, and that the core member is laterally arranged horizontally between first and second molding units.

Abstract: A composite insulator having a core member and a housing member integrally arranged around the core member, the housing member being constructed by a trunk portion and a shed portion, has a creepable distance extending means arranged on a lower plane of the shed portion. Moreover, a segment used for producing the composite insulator has a pair of segment molds detachably connected at a partition plane having a through-hole at its center portion through which the core member is arranged, an upper plane forming portion arranged at its one end surface for defining an upper plane of the shed portion, and a lower plane forming portion arranged at its other end surface for defining a lower plane of the shed portion; and a partition for forming the creepage distance extending means arranged at the lower plane forming portion.

Abstract: A segment used for producing a composite insulator having a core member and a housing member arranged around the core member and constructed by a trunk portion and a shed portion is disclosed. The segment has a pair of segment molds detachably connected at a partition plane and a heating and cooling passage arranged in the segment molds respectively. The segment molds have a through-hole through which the core member is arranged, an upper plane forming portion arranged at its one end surface for defining an upper plane of the shed portion, and a lower plane forming portion arranged at its other end surface for defining a lower plane of the shed portion. A heating or cooling medium is passed through the heating and cooling passage. Moreover, a mold is constructed by integrating a plurality of segments with the heating and cooling passage mentioned above.
