  • Publication number: 20140131141
    Abstract: The elevator operation control method according to the embodiment estimate the amount of shake of a long object which moves accompanying lifting and lowering of a passenger cage by way of simulation based on the amount of shake of a building in which an elevator is installed and current position information of the passenger cage of the elevator. The elevator operation control method change every second a physical model of the simulation according to the position of the running passenger cage, and simulate in real time the amount of shake of the long object from a current amount of shake of the building and position information of the running passenger cage. The elevator operation control method compare the amount of shake of the long object calculated by the simulation and a threshold, and perform a control operation according to the result.

  • Publication number: 20140123774
    Abstract: An automatic analyzer uses probes for detecting liquid levels based on a capacitance detection method. Erroneous detection of liquid levels due to interference caused by the frequency difference of oscillators is reducted. When frequencies f1 and f2 of respective detector ocillators, which are originally equal to each other, are different by approximately several Hz from each other due to a manufacturing variation, oscillation waveforms are added to liquid level detection voltages, causing a premature determination that the probes have contacted the liquid surface before actual contact therewith. By setting the difference between the frequencies f1 and f2 of the detector oscillators to be in the range of several kHz, an oscillation waveform corresponding to the difference between the frequencies is added to the detection voltages, but the amplitude values of the high-frequency components are attenuated by high-frequency attenuators, thereby ensuring accuracy in the liquid level detection.
