  • Patent number: 10403412
    Abstract: An optical tweezers device determines trapping force data indicating a trapping force for a particle on the basis of a distance between the particle trapped by focusing laser beam with a lens and a focal point of the lens. The optical tweezers device determines a difference between a trapping force theoretical value that is estimated according to a linear relationship between the distance between the trapped particle and the focal point of the lens and the trapping force for the particle and the trapping force indicated by the trapping force data. The optical tweezers device controls a laser power of the light source on the basis of the difference of the trapping force.

  • Publication number: 20190246444
    Abstract: A gateway device is wirelessly connected to a mobile device and a control device that is connected to the gateway device and controls the mobile device. The mobile device reports a completion report indicating completion of a movement work according to a movement control instruction from the control device, and wherein the control device includes a work control unit that transmits the movement control instruction to the mobile device. It is determined whether or not a failure has occurred in communication between the control device and the gateway device, and it is determined whether or not the movement control instruction executed by the mobile device passes through the gateway device in which the failure determined by the failure detection unit has occurred, and stops transmission of the movement control instruction of passing through the gateway device in which the failure has occurred to the mobile device.

  • Publication number: 20180073781
    Abstract: In a conveying device, a belt conveyer is equipped with a conveying portion that conveys an object from an upstream region to a downstream region. A heat source heats the conveyed object. A cooling portion is located downstream of a terminal end of the belt conveyor and cools the object. A first thermoacoustic cooling device cools the cooling portion. A first prime mover generates acoustic waves from heat transmitted from the first heat source. A first receiver generates, from the acoustic waves, cooling heat corresponding to a cooling temperature that is lower than a temperature of the heat source.
