  • Patent number: 11430589
    Abstract: The disclosure provides a hybrid magnet structure which includes two dipole magnets assemblies arranged oppositely, and each dipole magnet assembly includes a permanent magnet, two iron cores, and a moveable magnetic field shunt element. The hybrid magnet structure is adapted to focus particle beams of different positions by applying an adjustable gradient magnetic field in the horizontal or vertical direction of the particle beam. By passing the charged particle beams through the gradient magnetic field established between the two dipole magnets, the aspect of focusing the charged particle beam is achieved. In addition, the intensity of the gradient magnetic field can be altered by adjusting the gap between the movable magnetic field shunt element and the permanent magnet, thereby controlling the particle beam size on a specific axis for different energies or masses of the charge particles.

  • Publication number: 20220201853
    Abstract: Provided herein are methods for manufacturing a multilayer circuit structure having embedded circuits and the multilayer circuit structure made thereby. A substrate having at least one existing circuit on the surface is provided, then a dielectric layer is formed to cover the existing circuit. A metal layer is subsequently formed on the dielectric layer. The metal layer is made into a metal mask with a pattern by photoimaging, then the pattern is transferred to the dielectric layer underneath by plasma etching to create multiple trenches and pads at the same time. After vias are made at the pads, a conductive metal is deposited into the trenches and vias to form an embedded trace layer with excess conductive metal in the dielectric layer. The excess conductive metal is removed to obtain a new circuit embedded in the dielectric layer and is coplanar with the surface of the dielectric layer.

A substrate having at least one existing circuit on the surface is provided, then a dielectric layer is formed to cover the existing circuit. A metal layer is subsequently formed on the dielectric layer. The metal layer is made into a metal hard mask with a pattern by photoimaging, then the pattern is transferred to the dielectric layer underneath by plasma etching to create trenches and pads for vias at the same time. After vias are made on the pads, a conductive metal is deposited into the trenches and vias to form an embedded trace layer in the respective dielectric layer. The excess conductive metal is removed to obtain a new circuit embedded in the dielectric layer and is coplanar with the surface of the dielectric layer.

    Abstract: A bicycle hydraulic assembly includes a casing, a first piston, and a second piston. The casing has a hydraulic chamber, an inlet channel, and an outlet channel connected to the hydraulic chamber. The first piston is located in the hydraulic chamber. The second piston is sleeved on the first piston. The second piston has a first end portion and a second end portion opposite to each other. The first end portion is wider than the second end portion located farther away from the inlet channel than the first end portion. When the first piston is moved a distance smaller than a threshold distance, the first piston is moved relative to the second piston while the second piston is stationary relative to the casing. When the first piston is moved a distance greater than the threshold distance, the first piston forces the second piston to move relative to the casing.
