  • Patent number: 11946916
    Abstract: A waveform processing assistance device includes an acquirer that acquires a plurality of waveform data obtained by an analysis of a sample, a selector that selects reference data among the waveform data, an extractor that extracts correct answer peaks and correct answer data from the reference data a determiner that determines each processing section including a correct answer peak and each parameter initial value, a waveform processor that performs waveform processing in each determined processing section based on each parameter initial value, an adjuster that generates a parameter adjustment value at which a waveform processing result obtained in each processing section matches or approximates corresponding correct answer data, and a program creator that creates a waveform processing execution program that includes an instruction to execute waveform processing using the parameter adjustment value in each processing section.

  • Patent number: 9212943
    Abstract: An ultrasonic reactor water level measuring device and an evaluation method are provided and prevent a reduction in the measurement accuracy of a water level that is in a wide measurement range. The ultrasonic reactor water level measuring device includes an upper tube extending from a gas phase portion in a reactor, a lower tube extending from a liquid phase portion in the reactor, measurement tubes connected to each other and arranged at multiple stages between the upper tube and the lower tube, and units for generating and receiving ultrasonic waves, the units being arranged at bottom portions of the measurement tubes. The ultrasonic reactor water level measuring device measures levels of water within the measurement tubes and calculates a water level within the reactor from the sum of the measured water levels, the sum excluding an overlapped part of the measurement tubes.
