  • Publication number: 20220274164
    Abstract: A surface treatment method for a hydrogen absorbing alloy powder of the present disclosure is used for a surface treatment on a hydrogen absorbing alloy powder containing rare earth elements and nickel as constituent elements, including an immersion process in which the hydrogen absorbing alloy powder is immersed in an aqueous alkaline solution; and a removal process in which a liquid containing the hydrogen absorbing alloy powder immersed in the aqueous alkaline solution is introduced into a liquid cyclone, and undesired substances having a smaller specific gravity than the hydrogen absorbing alloy powder adhered to the surface of the hydrogen absorbing alloy powder are removed.

  • Patent number: 11408776
    Abstract: Disclosed is a power supply device including a battery having an exhaust valve that opens when an internal pressure becomes higher than a set pressure, the battery being housed in a case, a temperature sensor that detects a temperature in the case, and a detection circuit that detects opening of the exhaust valve at a detected temperature detected by the temperature sensor. In this power supply device, the detection circuit detects that a high temperature time (t1) from a timing at which a rate of rise (?T/?t) of the temperature detected by the temperature sensor is higher than a rise rate set value and exceeds the rise rate set value to a timing at which the detected temperature falls to less than or equal to a reference temperature is longer than a high temperature time set value, and detects the opening of the exhaust valve.

  • Publication number: 20190265116
    Abstract: A torque detection device in a power transmission device including a speed change mechanism, the torque detection device detecting torque on a rotary shaft that rotates with a gear, the torque detection device including: a first encoder having a first detected portion and directly fixed to the rotary shaft so as to rotate with the rotary shaft; a second encoder having a second detected portion and directly fixed to the gear so that the second encoder rotates with the gear and that the second detected portion is located near the first detected portion; and a rotational displacement detection sensor that detects rotational displacements of the first detected portion and the second detected portion.

  • Patent number: 8646840
    Abstract: A vehicle seat assembly includes a base portion, a support bracket, a seatback frame and a cushion frame. The support bracket is pivotally coupled to the base portion about a first axis. The seatback frame is pivotally coupled to the support bracket about a second axis that is spaced apart from the first axis. The cushion frame is pivotally coupled to the support bracket about a third axis that is spaced apart from both the first and second axes, such that the seatback frame and the cushion frame move with the support bracket relative to the base portion when the support bracket pivots about the first axis.

  • Publication number: 20040140305
    Abstract: The present invention provides a housing box by which means for efficiently transporting clothes with hangers at a low cost by using a general-purpose container such as a dry container. Connecting members for respectively connecting front ends of a pair of side structures to each other and rear ends to each other are provided. A bending device for bending the connecting members inward is provided. The box can be changed between an unfolded attitude in which the respective connecting members are kept extended and the hanger pipes are mounted to bridge the pair of side structures to form a housing space and a folded attitude in which the respective connecting members are bent inward to thereby bring the side structures close to each other.
