Title: Reed relay
Inventor: NISHIDE YOSHIO
IPC: H01H1/66
Filed: 1990-02-22
Abstract: PURPOSE:To facilitate the detection of the direction of a current supplied to a load by providing stationary contacts disposed opposite to each other in a state previously magnetized in poles different from each other, and a flexible movable contact positioned between the stationary contacts and to be magnetized with energization to a coil, and attracting the movable contact to be connected to either of the stationary contacts according to the direction of energizing to the coil. CONSTITUTION:When a current, for example, in the direction indicated by an arrow A is supplied to a relay coil 11d, the tip end of a movable contact 11c is magnetized to an S pole so that the contact 11c and a stationary contact 11a attract to be connected to each other. Upon supply of a current in the direction indicated by an arrow B, the tip end is magnetized to an N pole so that the contact 11c and another stationary contact 11b attract to be connected to each other. Consequently, the terminals of the stationary contacts 11a, 11b and movable contact 11c are drawn via a detection unit 14. With application of a constant voltage to the terminals, the current is supplied to either of the contacts 11a, 11b. Accordingly, the direction of the current supplied to the relay coil 11d can be detected with ease. Namely, it is possible to facilitate the detection of the direction of the current supplied to a load 13 connected to a telephone line.

CONSTITUTION:A multipolar permanent magnet 9 is held fixed, and a nonmagnetic cylinder 8 which is a toner supporting body is rotated in the same direction on the plane proximate to an electrostatic image holding surface 1. As the cylinder 8 revolves, the one-component insulation-characteristic ferromagnetic toner 12 which is being fed from a toner vessel 14 is coated on the nonmagnetic cylinder surface. At this time, the trichoelectric series of both are so selected that the load of the polarity reverse from that of the electrostatic image charge is applied upon the toner particles by the friction between the cylinder surface and the toner particles. Further, an iron-made doctor blade 10a is disposed in proximity to the cylinder surface. The blade 10 regulates the thickness of the toner layer thinly and uniformly with a sheet of which the longitudinal direction is the generator direction of the nonmagnetic cylinder surface.
