  • Publication number: 20210010539
    Abstract: A roller-type linear guide with an oil storage function and an oil storage accessory thereof are disclosed. The roller-type linear guide includes a rail, a slider unit, a plurality of rollers, and an oil storage member. The slider unit is mounted on the rail to form a circulation passage. The rollers are disposed in the circulation passage to drive the slider unit to reciprocate on the rail. The rollers each have a rolling surface. A non-load passage of the circulation passage has two first inner surfaces facing the rolling surface. The oil storage member is disposed in a concave portion of the first inner surfaces, thereby lubricating the rollers running in the non-load passage. The oil storage accessory is disposed in a through hole of the slider rigid body to form the non-load passage.

  • Publication number: 20200328665
    Abstract: A linear motor structure includes a stator, at least one moving member, and at least one linear member. The stator extends along an axial direction and has an electromagnetic acting surface. The moving member has an elongated hollow portion passing through the moving member and having a closed annular shape. The stator passes through the elongated hollow portion in the axial direction and is encircled by the moving member. The moving member has an electromagnetic portion relative to the electromagnetic acting surface of the stator. The moving member is electromagnetically reciprocated along the axial direction. The linear member extends along the axial direction. The moving member is coupled to the linear member. Because the moving member is closed and annular, the electromagnetic portion has sufficient supporting rigidity and won't be deformed by the electromagnetic action.

  • Publication number: 20200312711
    Abstract: An opening is formed within a dielectric material overlying a semiconductor substrate. The opening may comprise a via portion and a trench portion. During the manufacturing process a treatment chemical is placed into contact with the exposed surfaces in order to release charges that have built up on the surfaces. By releasing the charges, a surface change potential difference is reduced, helping to prevent galvanic corrosion from occurring during further manufacturing.

  • Patent number: 10784760
    Abstract: A core-type linear motor includes: a stator extending in an axial direction, with magnets arranged at intervals in the axial direction, wherein each magnet and its spacing from an adjacent magnet constitute a magnet unit; and a rotor opposite the stator and linearly movable in the axial direction, with coil assemblies arranged side by side in the axial direction. Each coil assembly includes a core with an active portion wound with a coil and a supporting portion. Three coil assemblies have substantially the same length in the axial direction as four magnet units. When the length of each magnet unit is defined as 1, the length of each active portion is 0.3 to 0.5, and the height of each supporting portion, 0.28 to 0.38. These size ratios help increase the motor constant, lower the cogging force, and reduce positive attraction between the rotor and the stator.

  • Patent number: 9148047
    Abstract: A coil unit and coil assembly for iron-less liar motor and the coil unit includes two vertical function sides and two axial non-function sides. The multiple units are alternatively connected to each other by inserting the vertical function side of one coil unit into the hollow portion of the adjacent coil unit so as to form a coil assembly. The width of the vertical function side is D1 and the distance between two respective insides of the two vertical function sides is D2. D2=m×D1+?L, wherein m representing the number of the vertical function sides of other coil units received in the vertical direction of the hollow portion. The ?L is the width of the gap which receives a separation plate between the two adjacent vertical function sides to increase the efficiency of dissipating heat or insulation when current passes through the coil assembly.
