    • An IC socket comprises socket board having a plurality of contacts for contacting corresponding lead terminals of an IC package, and a movable plate closed with respect to an upper surface of the socket board. The contacts are brought into contact with the corresponding lead terminals when the movable plate is laterally moved in one direction along the upper surface of the socket board, and the contacts are moved out of contact with the corresponding lead terminals when the movable plate is laterally moved in the other direction. The IC socket further comprises at least one block integrally formed on each of two opposite side edges of one of the movable plate and the socket board, which side edges are parallel with the lateral movement direction of the movable plate relative to the socket board. On each of the two opposite side edges, a pin is inserted into the at least one block so as to be fixed to and movable with the at least one block. At least one pin restricting piece is integrally formed on each of the opposite side edges of the other of the movable plate and the socket board, which side edges are parallel with the lateral movement direction of the movable plate relative to the socket board. The pin restricting pieces are respectively slidingly abutted against surfaces of the pins.

    • An electric motor is disclosed wherein a positive magnetic pole winding and a negative magnetic winding for each of plural phases in each of two systems are wound respectively around two teeth adjoining each other of those teeth which are arranged circumferentially on an internal surface of a stator to protrude radially inwardly. Thus, in either one of the case that the rotor is rotated by the excitation of all the windings in both of the two systems and the case that it is rotated by the excitation of the windings in either one of the two systems, the windings adjoining each other serve as a set and magnetically attract the rotor thereby to rotate the same. In either case, the position sensor is able to precisely detect the position of the rotor relative to the windings. As a result, the torque ripple which occurs when the rotor is switched from being rotated by the excitation of the windings in the two systems to being rotated by the excitation of the windings in either one system only can be suppressed, so that the electric motor can be driven smoothly.
    • 公开了一种电动机,其中在两个系统中的每一个中的每个相中的正磁极绕组和负磁性绕组分别围绕在定子的内表面周向布置的那些齿相邻的两个齿缠绕到 径向向内突出。 因此,在通过两个系统中的所有绕组的励磁使转子旋转的情况中的任一个以及通过两个系统中的任一个中的绕组的激励来旋转转子的情况下,绕组相邻 彼此用作集合并磁力吸引转子,从而旋转转子。 在任一情况下,位置传感器能够精确地检测转子相对于绕组的位置。 结果,可以抑制当转子通过两个系统中的绕组的激励而被转动以通过两个系统中的绕组的激励而旋转而产生的转矩波动,使得电动机 可以顺利开车。
