  • Publication number: 20240152026
    Abstract: A quantum absorption spectroscopy system (1) includes a pump light source (11), a quantum interferometer (21), and a spectroscope (31). The pump light source (11) emits pump light. The quantum interferometer (21) causes quantum interference between a plurality of physical processes in which a quantum entanglement photon pair of a signal photon and an idler photon is generated through spontaneous parametric down-conversion of the pump light, a sample being arranged on a propagation path of the idler photon. The spectroscope (31) detects a signal photon from the quantum interferometer (21). The quantum interferometer (21) includes a single mode fiber (SMF) portion optically coupled to at least part of a propagation path of the signal photon and the propagation path of the idler photon.

  • Patent number: 11971682
    Abstract: A cartridge includes a first unit including a photosensitive member, and a second unit including a developer bearing member and a force receiving portion, the second unit being configured to be rotatable about a first axis to move with respect to the first unit between a first position and a second position. In a state where the first unit is in a same posture as when an image forming operation is performed, the second unit is disposed at the second position by its own weight. The developer bearing member is configured to be rotatable about a second axis. When seen in the direction of the first axis, a first distance between the force receiving portion and the second axis is smaller than a second distance between the first axis and the second axis and a third distance between the first axis and the force receiving portion.

  • Patent number: 11365977
    Abstract: A route generation device and a travel control device for suppressing a target route of a vehicle to be discontinuous before and after starting a lane change are obtained. A position obtaining unit obtains location information of the vehicle. A first route extraction unit extracts the target route as first points in sequence assuming that the vehicle continues to travel in the lane in which the vehicle is traveling before starting the lane change. The second route extraction unit extracts the target route a target route as second points in sequence assuming that the vehicle is currently traveling in an adjacent lane in which the vehicle travels after completing the lane change, and the vehicle continues to travel in the adjacent lane. The route calculation unit calculates the third points representing the target route.

  • Publication number: 20210347359
    Abstract: A lane information detection unit detects the shape and the road width of a traveling lane of a vehicle. A present transverse position detection unit detects a present transverse position indicating a present traveling position of the vehicle in the width direction of the traveling lane. A driver-corresponding transverse position setting unit sets a driver-corresponding transverse position corresponding to a driving tendency of a driver. An upper/lower limit value setting unit sets upper/lower limit values that the driver-corresponding transverse position can take, in accordance with the road width. Then, when change in the road width is detected, a transverse position control amount calculation unit sets, as a target transverse position, the driver-corresponding transverse position within the upper/lower limit values in which the change is reflected, and calculates a transverse position control amount for the vehicle from the present transverse position of the vehicle.
