  • Patent number: 7420118
    Abstract: An electric wire with coating of polyvinyl chloride family resin composition is disclosed which has a coating layer containing a polyvinyl chloride family resin composition comprising polyvinyl chloride family resin and one or more compounds selected from calcium soap, zinc soap and hydrotalcite. The polyvinyl chloride composition does not comprise either or both of a lead compound and a ?-diketone compound having a melting point less than 100° C. A plasticizer can be further added to the composition so as to obtain a heat-stable vinyl chloride composition. A cable covered with the polyvinyl chloride family resin composition is also disclosed, including a cable having electric wires coated with the polyvinyl chloride family resin composition.

  • Patent number: 7005149
    Abstract: The present invention relates to a method for producing fruit vinegar, comprising subjecting a flavorful acid citrus fruit juice with an inherently low citric acid content and/or a flavorful acid citrus fruit juice with a reduced citric acid content by acid reduction treatment as a raw material, after alcohol is added thereto by alcohol fermentation and/or addition of alcohol, to acetic acid fermentation; although acetic acid fermentation using a flavorful acid citrus fruit juice with a high citric acid content has been hitherto unsuccessful, the reduction treatment of citric acid content in the present invention has realized an efficient production of fruit vinegar with good body, savory taste and mild sourness that has not been hitherto produced.

  • Patent number: 6903264
    Abstract: An electric wire with coating of polyvinyl chloride family resin composition is characterized by having a coating layer including polyvinyl chloride family composition obtained from adding more than one of any calcium soap, zinc soap and hydrotalcite to resin including polyvinyl chloride resin as a main constituent, and further adding thereto plasticizer so as to obtain a heat-stable vinyl chloride composition, and further adding thereto as stabilization auxiliaries high-melting-point ?-diketone compound having a melting point more than 100° C. out of ?-diketone compounds expressed by a general formula of R.CO.CH2.CO.R?.

  • Patent number: 5132124
    Abstract: A powdered drink brewing bag comprising a filter paper bag body having gusset walls and containing a powdered material, such as coffee powder therein. A frame type support member formed of thick paper is bonded to opposing walls of the bag body in the vicinity of the upper edge thereof in such a manner that the bag body is held at both surfaces thereof between the opposite surfaces of the support member. Arm portions project outwardly from the portions of the support member which correspond to both sides of the filter paper bag body, and are provided with folds and handles so that the arm portions are bent in the shape of the letter "Y" in plan to enable the gusset walls to be expanded. Accordingly, the upper edge portion of the bag body can be maintained in a largely opened state, so that the hot water can be poured thereinto easily. This enables the brewing bag to be used easily, and a drink, such as coffee to be obtained conveniently.
