Abstract: A device and method for using a screw to connect wires to an electrical component, without the need for additional tools, to manipulate the wire around the screw. The device is a screw with a body, head, and hole perpendicular to the rotational axis of the body and adjacent to the screw head. A wire is connected to the electrical component by inserting the end of an exposed wire into the hole through the screw and then tightening the screw, causing the exposed wire to loop around the screw and become secured between the screw and electrical component in a secure manner. For larger holes, a section with a larger diameter than the screw body may be disposed between the screw body and screw head.

Abstract: A motor may include a coil bobbin having a drum part around which a winding is provided, a terminal block formed on an outer periphery of the coil bobbin, at least a pair of terminal pins which are protruded from a first wall face of the terminal block, and a groove part formed in the first wall face of the terminal block and is opened to a second wall face of the terminal block that is perpendicular to the first wall face. Both ends of the winding are respectively bound to a pair of the terminal pins from the second wall face side through the groove part of the terminal block. A stator core may be utilized instead of the coil bobbin. In this case, the terminal block may be fitted to the stator core.

Abstract: An obstruction across the flow chamber creates a one dimensional convergence of a sheath fluid. A passageway in the construction directs flat cells near to the area of one dimensional convergence in the sheath fluid to provide proper orientation of flat cells at fast rates.
