Abstract: A method includes providing a substrate having a surface such that a first hard mask layer is formed over the surface and a second hard mask layer is formed over the first hard mask layer, forming a first pattern in the second hard mask layer, where the first pattern includes a first mandrel oriented lengthwise in a first direction and a second mandrel oriented lengthwise in a second direction different from the first direction, and where the first mandrel has a top surface, a first sidewall, and a second sidewall opposite to the first sidewall, and depositing a material towards the first mandrel and the second mandrel such that a layer of the material is formed on the top surface and the first sidewall but not the second sidewall of the first mandrel.

Abstract: A resonant vibration actuator is provided, comprising: a casing, a mover, a plurality of electromagnet sets, two elastic suspensions, and a connecting circuit; the casing is provided with connection terminals for connection on the outside; the mover comprising: a mover frame, a plurality of permanent magnet units, two magnetic backs, the permanent magnet units and the magnetic backs being arranged in the mover frame; the electromagnet sets being arranged between two permanent magnet units of the mover; the elastic suspensions being connected to the casing and the mover respectively through two connection portions at both ends; the connecting circuit being used to connect the electromagnet set and the connection terminals outside the casing; wherein, by energizing the electromagnet set, the electromagnet acts on the permanent magnet unit to make the mover move relatively in the casing to generate vibration.

Abstract: A rotary display stand includes: a base; a driving unit mounted to the base; a first magnet unit mounted to the base and driven by the driving unit to rotate about an axis relative to the base; and a support supported on the base and including a second magnet unit that is magnetically driven by the first magnet unit to rotate about the axis relative to the base.

Abstract: An amelioration of a mouse button structure mainly comprises an arched main body suitable for the grasp of the human hand; the main body is provided with at least two buttons on the top and two containers at the top end having openings leading to an interior; on a circuit board within the interior is provided with a pressing switch slot for connecting to the buttons; the characteristic of the invention is that the mouse buttons are designed as dynamic eyes such that the moving-eye buttons sway when using the mouse, thereby giving an entertaining effect.

Abstract: An eye assembly for toys, stationery or ornaments includes an outer shell disposed and fixed with a mobile eyeball. The eyeball is provided with a mobile cover at the top thereof and at the inner side of the outer shell, and an eyelid cover at the front thereof for forming an eye structure. The eye structure appears vivid and appealing when being erected and lain by opening and closing the eye for that the internal mobile cover is situated at different positions relative to the eyeball.

Abstract: An enhanced structure of an animated ornament composed of a globular shell, a hollow ball, a piece of non-magnetic, high-density material (such as copper, tin, plastic etc.), an inner magnet and an outer magnet. The hollow ball, having decorative figures, is smaller than the globular shell and is included in the globular shell. The space in between the globular shell and the hollow ball is filled up with liquid so that the hollow ball floats in the liquid and, when being shaken, turns around in all directions. Inside the lower part of the hollow ball attached a piece of non-magnetic, high-density material, such as plastic, copper and tin, and an inner magnet is fixed on the top of the non-magnetic material.
