Latest Patents
Yamada's latest patents include a method and apparatus for performing chromatography analysis. This invention relates to a chromatography analysis method and a system that can automatically determine the constituents to be detected in an unknown sample based on measurements from a standard sample. The process involves separating the standard sample to obtain its chromatogram, extracting necessary information to identify peaks corresponding to the constituents, and applying time windows to the chromatograms of the unknown sample. This innovation eliminates the need for operators to input retention times for each constituent, streamlining the analysis process.
Another significant patent by Yamada is a high-pressure discharge lamp operating circuit. This circuit operates at low-frequency AC during the initial phase and transitions to high-frequency AC or DC operation during steady-state lamp operation. The design allows for a stabilized light output by detecting predetermined lamp characteristics or after a set time period post-ignition.
