摘要： A device for confirming the operation of an electromagnetic actuator which comprises a fixed core, a moving core detachably opposed to said fixed core to form a closed magnetic path together with the fixed core, and an electric winding wound around the closed magnetic path. The device is for detecting the displacement of the moving core relative to the fixed core, wherein the point of time at which the displacement of the moving core due to a direct current flowing through the electric winding is finished is detected using transient variations of the waveform of the direct current. Having a simple structure, the device is small in size and weight, low in cost, and highly reliable in confirming the operation of the actuator.

摘要： A water sprinkling control apparatus with a built-in memory holding a plurality of water sprinkling programs which determine water sprinkling timing for a large number of water sprinkling stations. It is possible to determine an optimum water sprinkling schedule by selecting one of the water sprinkling programs stored in the memory, correcting it if necessary, and combining a water sprinkling time and a water sprinkling date. Each of valve devices in the water sprinkling stations are successively controlled according to the thus-determined water sprinkling schedule, and, if necessary, the water sprinkling schedule is automatically and continuously repeated.

摘要： An attraction blade plate is disposed on a plunger of a plunger type electromagnet to improve the shape of the plunger and the shape of a fixed core, or a cylinder equipped with a single flange and made of a magnetic material is fitted to the axial-direction end portion of a coil bobbin. According to each technical means, the change rate of permeance of a magnetic path at the time of attraction can be made great and high sensitivity of the electromagnet can be accomplished. Attraction retention force is controlled by adjusting the area of the contact surface between the fixed core and a movable core. A permanent magnet is shaped in a toroidal shape and the direction of magnetization is formed in the direction of the thickness of the toroidal shape. Accordingly, magnetization of the permanent magnet becomes easier and the number of components can be reduced. In this manner, a compact and light-weight electromagnet can be mass-produced.

摘要： An electromagnetic actuator comprising: a fixed piece consisting of a soft magnetic member having a plurality of magnetic poles, the surfaces on one side thereof being fixed; a moving piece consisisting of a soft magnetic member that is opposed to the other surfaces of the magnetic poles of said magnet and opposed to the plurality of magnetic poles of said fixed piece via gaps, said moving piece having magnetic poles to form parallel magnetic circuits relative to the magnetomotive force of said magnet; and an electric winding which is wound on said fixed piece to serially excite the magnetic circuit which consists of said fixed piece and gaps of said moving piece relative to said magnetic poles. As a current is supplied to said electric winding, a difference develops in the magnetic flux between the opposing magnetic poles, giving rise to the occurrence of mechanical displacement between the fixed piece and the moving piece. Therefore, the electromagnetic actuator produces strong thrust with slight current.

摘要： An electromagnetic actuator apparatus is provided with a fixed member (1, 28) and a movable member (2E, 23). One of the members is defined as a first magnetic member consisting of a first electromagnet, and the other is defined as a second magnetic member consisting of a permanent magnet or a second electromagnet. The movable member is reversibly and movably held at a position at which a magnetic short-circuiting circuit which provides a stable attraction is formed between the fixed member and the movable member. The electromagnetic actuator apparatus operates so as to provide a monostable or bistable state.
