Abstract: A method for preparing a cross-dimension micro-nano structure array includes: S1. providing a workpiece immersed in the electrolyte as the first electrode, providing a trimming wire electrode as the second electrode and setting it above the workpiece, providing an interference beam adjuster and outputting multi-beam laser interference to irradiate the surface of the workpiece; S2. The power supply between the first electrode and the second electrode forms a loop, and drives the trimming wire electrode to reciprocate relative to the workpiece, and the workpiece undergoes electrochemical dissolution or electrochemical deposition at the corresponding position of the trimming wire electrode, and form a micro-nano structure array without a mask, and solves the problem of low output power of the existing ultrashort pulse power supply, improves the processing accuracy of the micro-nano structure array, does not require electrolyte for high-speed flow, and improves system safety and reduce the cost.

Abstract: Disclosed by the present invention are an aqueous polyurethane functional mask substrate and an application thereof. Two kinds of water-based polyurethane dispersions are used as the main components of the mask substrate. The transdermal penetration and absorption of functional ingredients such as whitening, moisturizing and anti-aging ingredients in facial mask products are promoted by means of the special cross-linked structures of polyurethane films. During use, a mask is evenly applied to the face; and after the mask dries, the entire mask may be removed directly or removed after being moistened using water. The mask substrate according to the present invention is also applicable to body masks such as a hand mask, a neck mask and a back mask.

Abstract: Provided is a semiconductor device applicable to both types of packages regardless of whether or not double bonding of a lead frame pad is allowed. The semiconductor device includes: an operational amplifier; a feedback resistor; a reference voltage generation circuit; an output transistor; a first pad which is connected to an output terminal of the output transistor, and is to be selectively connected to a lead frame pad by a bonding wire; a second pad to be selectively connected to the lead frame pad by a bonding wire; and a connection switching element provided between the first pad and the second pad. In a case in which the second pad is connected to the lead frame pad by the bonding wire, the connection switching element interrupts connection between the first pad and the second pad.

Abstract: A revivification display method specialized for outline fonts that based on Stroke Centerline Technology of self-defined data format, which can be applied to any operating system to enforce the function of multi-font Chinese and multi-language characters. Because the stroke is described based on the centerline, and stroke thickness parameter and curvature change parameter are introduced, the fonts are infinitely beautiful. The data share of stroke-composed components and component-composed characters makes small memory consumption of font database and revivification program, and so the process of revivification is very fast. The font generator integrated circuit (IC) product of this method can be embedded into CPU to make the system directly to be Chinese localized without any additional cost, so the IC product is especially suitable for embedded applications with very wide application prospect.
