Title: Analysis method and apparatus for organic acid
Inventor: MURAYAMA TAKESHI
IPC: G01N30/96
Filed: 1985-04-24
Abstract: PURPOSE:To analyze organic acid in a liquid to be measured with a high sensitivity, by a method wherein organic acid discriminated from inorganic anions while being separated chromatographically, a cation exchange is done with a cation exchange membrane and then, the electric conductivity is detected. CONSTITUTION:A specimen sampling valve 5 is turned ON to change the internal passage thereof to the connection station as shown by the broken line from that as shown by the solid line. A reference sample within a weighing tube 5g is conveyed into a precolumn 6 and a separation column 7 by an elution liquid and organic acid is discriminated from inorganic cations while being separated chromatographically to be eluted. With such an arrangement, the liquid eluted from the column 7 is introduced into an internal chamber 8b of a suppressor 8, where the liquid is brought into contact with a removal liquid or the like in an external chamber 8c through a tube 8a to perform a cation exchange. In this case, since the elution liquid is acid as H2SO4 and the ion exchange group of a cation exchange membrane is H<+> type, the elution liquid passes through the suppressor as held therein and introduced to a detector 9 to detect the electric conductivity.

Title: Variable length error correcting device and its correcting system
Inventor: INOUE TORU
IPC: H03M13/23
Filed: 1991-04-19
Abstract: PURPOSE:To attain correct signal decoding by adding an inspection symbol to a variable information quantity and coding a transmission word so that coding/decoding of the variable length information is implemented efficiently without inserting a dummy bit. CONSTITUTION:An irreducible minimum error correction capability requested to a maximum information quantity to be transmitted is decided, the result is normalized by the sum of symbol numbers to decide a code word format for N symbols. Moreover, the inspection symbol number requested for accurate error correction is decided to an excess inspection symbol being a difference between the symbol number and the inspection symbol for the irreducible minimum error correction. Thus, the minimum information quantity when the information quantity to be transmitted is variable is decided. The information symbol is fed to the inspection symbol in the transmission information quantity inbetween and the result is normalized to the N symbol. The variable information in the memory 1 is sent to a coder 13 via a bus 2 and transmitted while the inspection symbol is added. A decoder generates a dummy symbol to calculate each syndrome for error correction.
