Abstract: In a heterojunction FET in which source and drain areas are formed by carrying out high temperature annealing process after carrying out ion implantation in areas to be formed into source and drain areas, conventionally, the N-type carrier supply layer and the N-type active layer are doped with Si. In place of doping with Si, doping with Se or Te is adopted. Thereby, in high temperature annealing process for activating the ion implanted areas, which serves as source and drain areas, unlike the Si donor, inactivation of donor due to reaction with F-atoms occurs scarcely with respect to the diffusion of F-atoms on the surface of the epitaxial substrate, which adhered during the process. Further, since the Se and Te are impurities from VI-family, when the Se or Te occupies any grid position of atoms from III-family or V-family, the Se or Te serves as the donor. Accordingly, a high performance heterojunction FET of little deterioration of the FET characteristics can be obtained.

Abstract: There was previously no monitoring method and monitoring apparatus which could measure dioxins at ppt levels and dioxin precursors at ppb levels with high sensitivity. According to this invention, organic and inorganic compounds containing highly electronegative elements are selectively ionized by atmospheric pressure chemical ionization, the ions produced are detected by a mass spectrometer, and their amount is measured. As a result, interfering substances such as nitrogen, air, hydrocarbons and carbon dioxide which are the main components of flue gas are eliminated, and dioxins or organochlorine compounds such as dioxin precursors can be selectively monitored.

Abstract: In a multiplexing apparatus, input data sequences of two types a and b are packetized using fixed lengths La and Lb so as to produce packets 3a and 3b, respectively. A flag 1 and headers 2a and 2b indicating a data type of packet are attached to the packets 3a and 3b for transmission. In a demultiplexing apparatus, when the header 2 cannot be properly identified due to a transmission error or the like, subsequent demultiplexing steps are performed by estimating that the subsequent data is the input data sequence a, when the length La occurs before the next flag 1, and estimating that the subsequent data is the input data sequence b, when the length Lb occurs.
