  • Publication number: 20240142324
    Abstract: A torque detection device includes a first yoke and a first magnetic guide member. A first opposing portion of the first magnetic guide member overlaps with a first-yoke ring of the first yoke when the first-yoke ring is projected onto the first opposing portion in an axial direction. Furthermore, the first opposing portion overlaps with an inner surface of a second tubular portion when the inner surface is projected onto the first opposing portion in the axial direction. A housing distance, which is a shortest distance measured from the first opposing portion to the inner surface, is longer than a yoke distance, which is a shortest distance measured from the first opposing portion to the first-yoke ring.

  • Publication number: 20200240986
    Abstract: A method for measuring an occupancy rate of a first specific binding substance in a cell population, including bringing a second and a third specific binding substance into contact with the cell population and counting the number of cells to which the second and the third specific binding substances binds, in which all of the first, the second, and the third specific binding substances are specific binding substances that bind to a target cell surface protein, the occupancy rate is a proportion of cells to which the first specific binding substance binds, in cells expressing the target cell surface protein, the second specific binding substance competes with the first specific binding substance, the third specific binding substance does not compete with the first specific binding substance, and the occupancy rate (%) is a value calculated by an expression: (1?(Number of cells to which the second specific binding substance binds/Number of cells to which the third specific binding substance binds))×100.
