  • Publication number: 20210134979
    Abstract: A method for fabricating gate structures includes providing a substrate, configured to have a first region and a second region. Dummy gate structures are formed on the substrate at the first and second regions, wherein each of the dummy gate structures has a first gate insulating layer on the substrate and a dummy gate on the first gate insulating layer. An inter-layer dielectric layer is formed over the dummy gate structures. The inter-layer dielectric layer is polished to expose all of the dummy gates. The dummy gates are removed. The first gate insulating layer at the second region is removed. A second gate insulating layer is formed on the substrate at the second region, wherein the first gate insulating layer is thicker than the second insulating layer. Metal gates are formed on the first and the second insulating layer.

  • Patent number: 10759296
    Abstract: A charging apparatus for electric vehicle may comprise a charging apparatus and an electric vehicle. The charging apparatus has a rectifier and a mobile connector, and the connector covered by a plastic cover has a primary coil electrically connected to the rectifier. The cover comprises a vertical first plane, and a plurality of first engaging portions formed at an outer periphery of the cover. The electric vehicle has a converter, a battery pack and a charge port, and the charge port covered by a plastic shell comprises a secondary coil electrically connected to the converter. The charge port has a vertical second plane and at least a second engaging portion. When the first plane of the connector is coupled to the second plane of the charge port, the primary coil and the secondary coil are spaced apart by a fixed distance, thereby achieving the effect of safe charging.

  • Patent number: 10294026
    Abstract: An automated warehouse storage and retrieval system may comprise at least an aisle, and each of two sides of the aisle has a shelf. A rail is laid along the aisle to enable at least an automated vehicle to move thereon. The automated vehicle has a platform, and a top surface thereof comprises at least a working station and at least a pick-and-place unit. Each of two lateral sides of the platform has two openings separated by a desired distance, and each of the openings has a climbing unit installed therein. The climbing units are configured to synchronously protrude from or move back in the openings. A side of the shelf faced to the rail has a plurality of vertical supporting members arranged in parallel, and each two adjacent supporting members are separated by the distance same as the two climbing units on the same lateral side of the platform.

  • Patent number: 10166616
    Abstract: A band saw machine includes a working platform, a cutting machine, a vertical displacement element causing the cutting machine to move vertically, a height sensor and a central processor. The working platform includes a reference plane for placing a workpiece. The cutting machine includes a driving wheel, a driven wheel, a band saw wound on the driving wheel and the driven wheel, and a motor that electrically drives the driving wheel. The band saw includes a starting cutting tooth and a processing cutting tooth sequentially arranged. The height sensor detects a starting cutting point of the workpiece farthest from the reference plane. The central processor receives information of a position of the starting cutting point, and controls a displacement speed of the vertical displacement element and a first rotational speed of the motor to cause the starting cutting tooth to first cut at the starting cutting point.

  • Patent number: 9740253
    Abstract: Electronic apparatus includes a display component, a base, a moveable case, and a transmission component. The display component includes a rotational shaft. The base is pivotally connected to the rotational shaft. The base has an opening. The moveable case is pivotally connected to the base. The moveable case can selectively cover or uncover the opening. The transmission component is disposed on the base. The transmission component is operatively connected between the rotational shaft and the moveable case. When the display component is rotated away from the base, the rotational shaft actuates the moveable case to rotate to uncover the opening through the transmission component. When the display component is rotated toward the base, the rotational shaft actuates the moveable case to rotate to cover the opening through the transmission component.
