Title: Dual-column, dual-detector gas detector and analyzer.
Inventor: ANNINO RAYMOND
IPC: G01N30/46
Filed: 1989-07-20
Abstract: A dual-column, dual-detector gas detector and analyzer employs both a photo-ionization detector and a flame-ionization detector. In a survey mode, samples of ambient air are driven through both detectors, and the outputs of both detectors are used to determine the presence of one or more gasses. In analysis mode, fixed-volume samples of ambient air are driven through two elution columns having different properties. The output of each elution column is fed to one of the detectors. The arrival times of gas peaks at the two detectors are employed to develop two lists of candidate gasses. The lists are cross-checked for the presence of each candidate on both lists. Candidates identified from their presence on both lists are identified. A further check attempts to identify candidates which are identifiable from their presence on one of the lists, and not on the other. Components identified in this way are added to the final list. Unidentified components are discarded, although their presence is noted and reported as unknown. Portability is retained by eliminating isothermal ovens and by reducing the quantity of hydrogen required. A simplified way of characterizing temperature corrections of elution columns is disclosed.

Abstract: A positioning correction for robots, capable of preventing a decrease in the positioning accuracy, which is ascribed to an error specific to a robot. Simultaneous equations including link length errors ( DELTA 11,  DELTA 12) and actual angles of rotation ( THETA 1,  THETA 2), of first and second links as unknown quantities are solved by using displayed angles of rotation of the first and second links (1, 2), which are obtained by sequentially carrying out the mastering concerning a plurality of known points, to determine the link length errors, errors ( DELTA x0,  DELTA y0) of positions of centers of pivotal movements of arms, errors ( DELTA  THETA 10,  DELTA  THETA 20) of angles of rotation of the links. When a robot is operated, the program-designated target positions of transfer of the front ends of the arms on the X- and Y-axes are corrected by using the errors of positions of centers of pivotal movements of the arms, and the actual link lengths are determined by using the link length errors. The angles of rotation of a servomotor relating to the first and second links is determined by a coordinate transformation processing based on the corrected positions of transfer of the front ends of the arms, actual link lengths and errors of angles of rotation of the links.
