The present invention provides a magnetic movement path control device including: a magnetic force moving unit including a permanent magnet generating a permanent magnetic force, a first pole piece attached to a first surface of the permanent magnet, and a second pole piece attached to a second surface of the permanent magnet; a first outer pole piece in contact with the magnetic force moving unit to form a magnetic path; a second outer pole piece in contact with the magnetic force moving unit to form a magnetic path different from the magnetic path formed by the first outer pole piece; and a magnetic path control member releasing or generating the magnetic path by allowing the magnetic force moving unit to come into contact with the first outer pole piece and be spaced apart from or come in contact with the second outer pole piece, wherein the magnetic force moving unit moves between a first position where at least one of the first pole piece and the second pole piece is in contact with the first outer pole piece and the second pole piece is spaced apart from the second outer pole piece to drop a target object and a second position where at least one of the first pole piece and the second pole piece is in contact with the first outer pole piece and the second pole piece is in contact with the second outer pole piece to lift the target object.

An objective of the present invention is to provide a conveyance device that can increase inductance variation while suppressing the lowering of thrust. A conveyance device 1 conveys an article 110 to be conveyed. The article 110 to be conveyed can be conveyed by a magnetic force. The conveyance device 1 comprises a plurality of electromagnets 25a and 25b. Each electromagnet 25a, 25b comprises: teeth 22, 22a, 22b, 22c and 22e including a magnetic body; and windings 21, 21a and 21b wound around the teeth 22, 22a, 22b, 22c and 22e. The conveyance device 1 comprises a yoke 26 for magnetically coupling the electromagnets 25a and 25b, and driving circuits 50a and 50b for supplying current to the windings 21, 21a and 21b. The teeth 22, 22a, 22b, 22c and 22e have a cavity 27 extending in the axial direction.

A magnetically levitating sterilizing toothbrush holder with associated toothbrush includes a holder generating a magnetic field and a toothbrush including a magnetic or ferromagnetic element. The holder and toothbrush are so configured that, when the toothbrush is placed in the holder, the force of gravity acting on the toothbrush is balanced in opposition to the magnetic force resulting from the interaction of the toothbrush's magnetic element with the holder's magnetic field, resulting in magnetic levitation of the toothbrush within the holder, thereby suspending the brush from all potentially contaminating surfaces. The holder further includes a sterilizing ultraviolet light source, whereby the operational end of the toothbrush with its bristles is bathed in sterilizing radiation when the brush is suspended in the holder.

A mover according to the present disclosure includes: a body to move; a second member; a suction unit; a location detection unit; a first moving part, and a second moving part. The second member moves in a state where the second member is combined with a first member provided for an object, as the body is displaced relative to the object. The suction unit is sucked to the object in the state where the second member is combined with the first member. The location detection unit detects a location of the body with respect to the object by detecting movement of the second member. The first moving part moves the body until the state where the second member is combined with the first member is established. The second moving part displaces the body relative to the object in the state where the second member is combined with the first member.

A solid-state magnet control unit includes a housing and magnet controller circuitry mounted within the housing. The magnet controller circuitry controls current passing through a magnet. The magnet controller circuitry includes a power storage unit, drivers in a bridge network, e.g., an insulated gate bipolar transistor (IGBT) in a bridge network, and dump circuitry. The dump circuitry limits circuit damage to the magnet controller circuitry and other components contained within the magnet control unit. When the dump driver is not operational, operation of the magnet control unit is automatically switched to first or second safety mode of operation.

A magnetic apparatus includes a first structure including a first non-magnetic material, a second structure including a second non-magnetic material on a first portion of the first structure, a third structure including the second non-magnetic material on a second portion of the first structure. The magnetic apparatus further includes a first magnetic structure adjacent to a first sidewall of the second structure, a second magnetic structure adjacent to a first sidewall of the third structure, a third magnetic structure adjacent to a second sidewall of the second structure, adjacent to a second sidewall of the third structure and extends onto a third portion of the first structure. A magnet is coupled with the first, second and third magnetic structures.

Apparatus and associated methods relate to a pick & place system that uses a magnetic core for both magnetic coupling with an assembly component and heating of the assembly component. The magnetic core has a component engagement surface configured to magnetically and thermally engage the component. A controller is configured to provide both AC current and DC current to an inductive coil wound about the magnetic core. DC current provided to the inductive coil induces a magnetic field within the magnetic core, thereby magnetically attracting the component when engaged with the component engagement surface. AC current provided to the magnetic core inductively heats the magnetic core, thereby heating the component when engaged with the component engagement surface.

An electromagnet for a thermography system comprising a first elongated magnetic core spaced apart from a second elongated magnetic core; at least a first shorting bar connecting substantially at a first end of the first elongated magnetic core and a first end of the second elongated magnetic core; and at least a first excitation coil configured to conduct electrical current.

A locking knife holder uses either mechanical or electronic locking systems to secure the knives into the holder. The electronic locking system includes the implementation of one or more electromagnets into the holder. The user can then selectively lock or unlock the knives in the holder by activating or deactivating, respectively the electromagnet. In other implementations, the mechanical locking system can use magnetic keys to unlock the mechanical locking system.
