  • Publication number: 20220221031
    Abstract: A structure is achieved capable of ensuring excellent transmission efficiency while preventing the occurrence of gross slipping at traction portions. A pressing device 9 rotationally drives a cam disk 21 by a pressing force adjusting motor 23, which causes an annular roller element 6a of a pair of annular roller elements 6a, 6b to displace in the axial direction. A controller 31, by adjusting the rotational drive of the pressing force adjusting motor 23, adjusts the surface pressure at the traction portions between rolling surfaces 16 of planetary rollers 7 and an inner-diameter side rolling contact surface 5 of an input shaft 3 and outer-diameter side rolling contact surfaces 12a, 12b of the pair of annular roller elements 6a, 6b to a target value.

  • Publication number: 20220208381
    Abstract: A medical care support device (11) includes an operation history acquisition unit (63), a prediction execution unit (64), and a display screen generation unit (62). The operation history acquisition unit (63) acquires an operation history in a case where a terminal device is operated. The prediction execution unit (64) predicts a next operation candidate in a case where the terminal device is input and operated by using a trained model generated by an external server learning the acquired operation history, the external server being installed outside the medical facility. The display screen generation unit (62) makes a proposal to the terminal device from the next operation candidate predicted by the prediction execution unit (64).

  • Publication number: 20220208380
    Abstract: Provided are a medical care support device, an operation method and a non-transitory computer readable recording medium storing an operation program thereof, and a medical care support system capable of promptly proposing necessary examinations and treatments in a case where a patient suffers from a chronic disease. A medical care support device (12) includes a display screen generation unit (62) and a prediction execution unit (63). The prediction execution unit (63) extracts a specific disease affecting a patient from acquired medical care information, and outputs a chronic disease and a complication that is likely to occur with a morbidity of the chronic disease as a prediction result. The display screen generation unit (62) proposes medical care practices for both the chronic disease and the complication.

  • Publication number: 20220140356
    Abstract: An object provides a power generation apparatus performing the purification of an Al alloy melt using scrap as raw material. A power generation apparatus includes: a container body with aluminum alloy melt and molten salt in a liquid junction with the aluminum alloy melt; an anode which is in contact with the aluminum alloy melt; and a cathode which is in contact with the molten salt. DC power is obtained from between the anode and the cathode by an anode reaction on the aluminum alloy melt side and a cathode reaction on the molten salt side. When the aluminum alloy melt and the molten salt are separated by a separator allowing ionic conduction between the aluminum alloy melt and molten salt, the power generation efficiency is enhanced. The amount of a reactant in the Al alloy melt is monitored by measuring the electrical quantity associated with the power generation.
