A clip, configured to support a furcation body, includes a keyhole member, a catch, a cover, and an arm. A dual-band antenna for low frequency and high frequency bands may be formed by the first radiating body. The device may be a gas chromatograph, a fluid calibration mechanism, a flame ionization detector, or the like. By having such topology, each phase power converter serves as a power conversion module independent of the others. In order to enhance the known veneer joining apparatus, the invention provides that the heating element is integrated into the slide bar.
