摘要:
A method for placing decoupling capacitors in an integrated circuit during placement and routing stage. In the placement method, a floor plan of the integrated circuit is created, and includes the relative locations of a plurality of functional units. A power mesh comprising a plurality power lines is then overlaid on the floor plan, and the floor plan is divided into a plurality of windows. A plurality of semiconductor cells are placed into a portion of the windows. It is then determined whether a residual area comprising two adjacent windows without functional units and semiconductor cells disposed therein and at least three parallel power lines running theretrough exists. A MOS capacitor is then placed in the detected residual area, serving as a decoupling capacitor.

A resin surface layer and a method of fabricating the same, and a composite having the resin surface layer and a method of fabricating the same, are provided. The method of fabricating the resin surface layer includes: (a) providing a base, made of a resin and including a plurality of additive particles randomly distributed in the base, wherein the additive particles are selected from a group consisting of pigments, dyes, colorants, coloring matters, and pearl powders; (b) moving the base constantly, and providing a magnetic field generating device to generate an exterior magnetic field that has an uneven distribution of magnetic field intensity, and is applied to the base to change the orientation of the additive particles, so that the additive particles are arranged in a predetermined form; and (c) drying the base to make a surface of the base exhibit a visual effect of 3D texture. Thus, the visual effect of any 3D texture can be achieved by controlling the orientation of the additive particles.
摘要:
An electronic device includes a first machine body and a second machine body adapted to be detachably assembled to the first machine body. The first machine body includes a first casing, a first hinge fixed to a side of the first casing, a second hinge pivoted to the first hinge along an axis, and a first connecting member disposed at the side and linked to the second hinge. The first and the second hinges are covered by the first casing. The second machine body includes a second casing and a second connecting member. When the first machine body is assembled to the second machine body, the first connecting member is fixed to the second connecting member, the second hinge is fixed jointly so that the first hinge is rotatable related to the second hinge. Accordingly, the first casing is rotatable related to the second casing.

A portable electronic device including a main body and a connecting port is provided. The main body has an containing cavity. The connecting port includes a base and at least one movable component. The base is disposed at the main body. The movable component is movably connected to the base and moves between an accommodated position and an operation position relatively to the base. When the movable component is located at the accommodated position, the height of the connecting port is less than or equal to the height of the containing cavity such that the connecting port is adapted to be accommodated in the containing cavity. When the movable component is located at the operation position, the height of the connecting port is greater than the height of the containing cavity, and a connector is adapted to be fixed between the base and the movable component.
