  • Publication number: 20240141616
    Abstract: Provided is a system or the like capable of reducing mental burdens on an operator who remotely operates a work machine, when an image range acquired by a real machine image pickup device loaded on the work machine is changed. A previous notice indicating a future change mode of a real space area projected in a work environment image displayed at a remote image output device 221 is output to a remote output interface 220. It is possible to make the operator who encounters a virtual sound source Vss displaced according to a displacement mode of the real space area and/or an icon image A1 in an arrow shape indicating the displacement mode of the real space area recognize beforehand that the real space area projected in the work environment image is to be displaced according to the displacement mode in the future.

  • Publication number: 20230085803
    Abstract: An objective of the present invention is to provide non-human animal models of cancer pathology, which mimic the hierarchical organization, cancer progression process, or biological property of human cancer tissues, and uses thereof. To achieve the objective described above, first, the present inventors transplanted cells of NOG-established cancer lines into NOG mice and morphologically observed the resulting tissue organization. As a result, the non-human animal models were demonstrated to exhibit pathologies (the hierarchical organization, cancer progression process, or biological properties of the cancer cells) similar to that of human cancer. Specifically, the present inventors succeeded in preparing non-human animal models exhibiting pathologies more similar to a human cancer, and cell culture systems using NOG-established cancer cell lines where the in vitro cell morphology is more similar to that of human cancer.

  • Patent number: 11028921
    Abstract: A gear position of a multi-position transmission, which shifts and drives a vehicle according to a turn motion of a shift drum, is detected by a plurality of sensors. An end portion of the shift drum is fitted with an end portion of an elongated shaft rotated coaxially with the shift drum. A first sensor which is fitted to other end portion of the elongated shaft detects a turn position of the elongated shaft. A second sensor which is located outside in a radial direction of the elongated shaft between the one end portion and the other end portion of the elongated shaft detects that the elongated shaft is located at a specified turn position. The first sensor and the second sensor are fitted from the outside of a transmission case of the multi-position transmission and are exposed to the outside of the transmission case.

  • Patent number: 10655732
    Abstract: A gear position detecting device includes a rotation angle sensor for detecting a turn position of a shift drum and a position sensor for detecting that the shift drum is at a neutral position. The rotation angle sensor is a volume sensor that linearly increases or decreases an output voltage according to a turning motion of the shift drum. The neutral position is set in such a way as not to overlap a dead zone. It is determined according to an output signal of the rotation angle sensor and an output signal of the position sensor whether the shift drum is at a reverse gear position located between the neutral position and the dead zone or a fifth gear position turned by 360 degrees from the reverse gear position. Such detecting device detects a gear position with a high accuracy even if the number of gear positions are increased.
