  • Patent number: 12036666
    Abstract: The present invention reduces tact time for a pick-and-place operation by an actuator. In a housing of the actuator, an air passage being a passage of air when sucking air from a hollow part of a shaft is provided. Furthermore, a sucking valve that sucks air from the hollow part of the shaft through the air passage and a suction detecting sensor to detect that a workpiece is suctioned onto a tip of the shaft are provided in the air passage. Then, in the housing, the air passage is disposed at a position on a side opposite to a linear motion motor that moves the shaft in an axial direction of the shaft, via the shaft.

  • Patent number: 11597898
    Abstract: A number analyzing method, a number analyzing device, and a storage medium for number analysis are disclosed, which enable, with high accuracy, analysis of the number or number distribution of particulate or molecular analytes according to the kinds of the analytes. A computer control program is executed on the basis of a data group of particle-passage detection signals which are detected by a nanopore device in accordance with passage of subject particles through a through-hole. Also, a particle type distribution estimating program is executed, to estimate probability density on the basis of a data group based on feature values indicating feature of the waveforms of pulse signals which correspond to the passage of particles and which are obtained as the particle-passage detection signals. Thus, the number of particles can be derived for each particle type.
