A composite cable that is able to prevent both the unfastening of the cable end from the connector and the occurrence of the bending distortion of the optical fiber, to both of which the expansion and shrinkage of the overall sheath is responsible, is provided. The composite cable comprises a stranded wire that is a strand of a plurality of insulated conductors each of which is a conductor with insulation covering thereon, an optical fiber ribbon that has a plurality of optical fibers parallelly-arranged in a row, and an overall sheath that covers the stranded wire and the optical fiber ribbon in a bundle, wherein the composite cable has a deterrent positioned on outer side of the stranded wire and the optical fiber ribbon parallelly-arranged in a row along the width direction of the overall sheath for deterring expansion and shrinkage of the overall sheath. Further, the composite cable has a bonding jacket between the deterrent and the overall sheath for making the deterrent adhere to the overall sheath; alternatively, the deterrent has a patterned indented shape on the surface thereof for making the deterrent adhere to the overall sheath.

An apparatus comprises a first member for holding a base part of a first connector and a sealing plug of a second connector, a second member for holding a sealing plug of the first connector and a base part of the second connector, and a stopper. The sealing plug of the first connector and the base part of the second connector are separated from the base part of the first connector and the sealing plug of the second connector respectively. The base part of the second connector and the base part of the first connector are threadedly fastened to each other, and the stopper stops the transfer of the rotation of the first and second gears to the sealing plug of the first connector and the base part of the second connector during the second rotation of the handle.

A sample transfer apparatus atomizer connected via tube to a sample receiver for micro-sampling. The sample receiver has a funnel-shaped upward opening and is connected to the tube at the base of the funnel. A control unit controls the apparatus to make sure that the sample injected into the sample receiver will be so positioned in the tube that a quantity of solvent is positioned nearer to the vaporizer than the sample, and preferably another quantity of solvent is positioned nearer to the side of the sample receiver relative to the sample. The presence of solvent in the tube positioned nearer to the vaporizer than the sample delays the sample being sucked by the vaporizer, this preventing interruption of the sample flow in the tube and making the atomic absorption waveform more stable.
