  • Publication number: 20200250831
    Abstract: A human detection system 18 includes: a camera 19 that acquires detection image data Dd of a detection region D, the detection region D being a prescribed region including a portion of a crane 1; a deviation determination unit 21c in which image data of the crane 1 included in the detection image data Dd acquired by the camera 19 in a state of being disposed at a reference position is set as reference image data Sd of the detection region D, and in which the detection image data Dd of the detection region D acquired at an arbitrary time by the camera 19 is compared to the reference image data Sd to determine whether the position of the camera 19 has deviated from the reference position; and a reporting unit 21d that reports that the position of the camera 19 has deviated.

  • Patent number: 10496221
    Abstract: A position detection device for detecting positions of a non-emitter and an emitter in a detection area includes one or more reflective members disposed around the detection area, illumination light sources to emit light toward the reflective member, light receiving sensors to receive light from the reflective member and light from the light emitter, and a control device to control the illumination light sources and the light emitter. Based on previous detection statuses of the non-light emitter and the light emitter, the control device sets a time ratio of a time of a non-light emitter detection mode to a time of a light emitter detection mode, and sets timings of the non-light emitter detection mode and the light emitter detection mode.

  • Patent number: 10365124
    Abstract: An electromagnetic actuator (1) includes sensor magnets (21a, 21b) disposed correspondingly to plungers (11a, 11b), respectively. The electromagnetic actuator (1) further includes a sensor core (22) made of a magnetic material and disposed in a position through which magnetic fluxes from the plurality of sensor magnets (21a, 21b) can flow, and a magnetic sensor (23) that is disposed in a part of the sensor core (22) through which the magnetic fluxes of the plurality of sensor magnets (21a, 21b) can flow in common, and that detects the magnetic flux, which varies in accordance with respective positions of the plurality of plungers (11a, 11b).

  • Patent number: 10364142
    Abstract: A method of forming a space includes a step of tenting, on a substrate having a recessed portion, a dry film including a dry film material that is to be a top plate on the recessed portion. The step of tenting the dry film includes a press period and a release period and performs a press-release cycle of the press period and the release period a plurality of times, a pressed state in which the dry film is pressed against the substrate by using a pressing member is maintained during the press period, and a released state in which the pressed state is released is maintained during the release period.

  • Publication number: 20190229356
    Abstract: A control unit of a fuel cell system acquires a service operating point, repeats a process of calculating a distance between the service operating point and a surging region, while transferring an operating point of a turbo compressor from a first operating point to a second operating point outside the surging region, sets opening degrees of a pressure adjusting valve and a bypass valve such that the turbo compressor operates at a required operating point, when the distance exceeds a threshold, and corrects at least one of the opening degrees of the pressure adjusting valve and the bypass valve such that the at least one of the opening degrees becomes larger than an opening degree set such that the turbo compressor operates at the required operating point, when the distance is equal to or shorter than the threshold.
