A method and apparatus for rapidly preprocessing and analyzing chemical substances, which places a vaporization bottle containing a sample inside a microwave device and uses a magneton driving device to drive the magneton inside the vaporization bottle to rotate as to stir the sample liquid even. In this semiconductor apparatus, one specific through FET and each of shunt FETs connected to each of through FETs other than the one specific through FET are simultaneously turned on in response to the same control signal inputted to the same control terminal. A formulation of Tretazicar in which the Tretazicar is protected from acid hydrolysis, wherein the formulation is present in a liquid form. The linking device also keeps track of all voice connections on the link. For that purpose, the control apparatus includes a ROM, a SRAM, a means for writing data in the SRAM, a selection means for selecting the output from the ROM or the SRAM in accordance with the addresses supplied to the ROM and the SRAM, and a control means for outputting the addresses to the ROM and the SRAM and operating with the output from the selection means as program data. The composite output signal is then transmitted over a communication medium, wherein information content of the optical signals are substantially equivalent, and wherein combining the optical signals before transmitting provides a reduction in RIN of the composite output signal compared to the RIN of a single optical signal transmitted over a communication medium.
