摘要： The invention provides a dielectric waveguide for transmitting millimeter waves or sub-millimeter waves. The dielectric waveguide is easily processed and connected even when having a small diameter, and can provide a connection structure exhibiting low transmission and return losses of high frequency signals. The dielectric waveguide includes a dielectric waveguide body and a dielectric waveguide end having a lower permittivity than the dielectric waveguide body. The dielectric waveguide body and the dielectric waveguide end are seamlessly and monolithically formed from the same material.

摘要： The invention provides a connector-attached dielectric waveguide that allows the dielectric waveguide to be easily connectable with an opposite component and is capable of forming a connection structure exhibiting low transmission and return losses of a high frequency signal. The connector-attached dielectric waveguide includes a dielectric waveguide and a connector. The dielectric waveguide includes a dielectric waveguide body and a dielectric waveguide end. The dielectric waveguide end has a smaller cross-sectional area than the dielectric waveguide body.

摘要： The present invention provides a method for producing a fluoropolymer aqueous dispersion having a significantly small particle size and excellent dispersion stability. The present invention relates to a method for producing an aqueous dispersion containing at least one fluoropolymer selected from the group consisting of polytetrafluoroethylene and melt-fabricable fluororesins excluding polytetrafluoroethylene. The method includes polymerizing a fluoromonomer in an aqueous medium in the presence of a fluorosurfactant and a polymerization initiator. The fluorosurfactant has a concentration in the aqueous medium of not lower than 0.8 times the critical micelle concentration of the fluorosurfactant.
