A movable-side magnet is provided to a movable portion in a vacuum chamber. A drive unit is provided outside the vacuum chamber, and drives the movable portion by exerting magnetic force on the movable-side magnet. The drive unit has a first magnet, a second magnet, and a moving mechanism (moving member). The first magnet exerts magnetic force of attracting the movable-side magnet. The second magnet is provided to be adjacent to the first magnet, and exerts magnetic force of repelling the movable-side magnet. The moving mechanism integrally moves the first magnet and the second magnet.

A magnetic bearing system for controlling magnetic coupling between a mobile carriage and a guideway and a method for controlling the magnetic bearing system. The magnetic bearing system includes at least one engine, which includes at least two poles, at least one permanent magnet and at least one coil. The engine is configured to be magnetically coupled to the guideway through at least one air gap.

A lock assembly comprising a base formed from a magnetic flux conducting material, the base secure to a chassis. A pin slidably disposed in the base and configured to move from a first open position to a second closed position. A magnet, disposed on a surface of a riser and configured to create a force on the pin that causes the pin to move from the open position to the closed position when the riser is disposed with the chassis.

A magnetic assembly structure has a main body and an inserting component. A first engagement slot of the main body receives a first magnetic component, and a first receiving slot of the main body penetrates a main body surface to form a main body opening on the main body surface. The first engagement slot and the first receiving slot are communicated with each other. The inserting component is inserted into the first receiving slot via the main body opening, and the first magnetic component moves into the first magnetic component receiving slot of the inserting component. The magnetic assembly is assembled with a less force, has higher safety, and is hard to be disassembled without allowance or explanations.

A filtration system interconnection structure having a filter manifold and a filter cartridge in magnetic communication with one another, such that a latching mechanism and latch blocking structure in the manifold secures the filter cartridge with a manifold sump when the filter cartridge is inserted within the manifold sump. The magnetic communication is formed between two complementary coded magnets capable of producing a magnetic shear force when in close proximity to one another. The magnetic shear force removes the latching blocking structure from interfering with the latch, allowing the latch to secure the filter cartridge. Movement of the latching blocking structure coded magnet relative to the filter cartridge coded magnet may be perpendicular or parallel with respect to each other. The filter magnet polarity transitions are aligned with the manifold magnet polarity transitions such that a shear force is generated between the magnets when the filter cartridge is inserted within the manifold sump housing, allowing for actuation of the latch blocking mechanism against a biasing force, and allowing the latch to move radially inwards against a separate biasing force.

A cavity is formed in a surface of a dielectric component on the permanent magnet side. The cavity has a bottom surface extending in a direction along one main surface and a side surface extending in a thickness direction crossing the bottom surface. At least a part of the permanent magnet is disposed in the cavity. A surface of at least a part of the permanent magnet disposed in the cavity is fixed to both of the bottom surface and the side surface through an adhesive.
