  • Patent number: 9797536
    Abstract: Provided are an article including a joint portion of a fluororesin having sufficient strength, and a method of producing the same. The article includes a joint portion including: a porous first layer of a first fluororesin; a second layer of a second fluororesin having a melting point lower than a melting point of the first fluororesin; and a non-porous third layer formed between the first layer and the second layer, the non-porous third layer including the first fluororesin.

  • Patent number: 7762283
    Abstract: The present invention provides a covering member including: a surrounding member including a heat insulating material and having a heat generating member or a heat insulating function, the surrounding member being wound from an open state so as to cover an object; and a fixing unit including: an engagement member including: a ring including a heat resistant elastic material; and a hook fitted to the ring; a holding member disposed on one end of the surrounding member, the holding member fastening the ring of the engagement member to hold the engagement member; and a receiving member disposed on one end of the surrounding member so as to correspond to the holding member, the receiving member including a receiving metal fitting to be engaged with the hook of the engagement member.

  • Publication number: 20090242548
    Abstract: The present invention relates to a tape heater including: at least one flexible fabric base formed from a heat-resistant thread, the at least one flexible fabric base including a first fabric base part and a second fabric base part; and a heater member, in which the heater member is interposed between the first fabric base part and the second fabric base pan. Since the heater member is interposed between the fabric base(s), the tape heater of the present invention exhibits superior flexibility and stretchability and is superior in easily being wrapped around a pipe, as well as reliably protecting the heater member. Further, tape heaters can be continually manufactured, so long as weaving or knitting of the fabric base(s) is caused to proceed while the heater member is interposed between the fabric base(s), to thus join the fabric base(s). Hence, enhancement of production efficiency and prevention of an increase in production cost can be attained.
