Abstract: A defect-reducing coating method is disclosed, which is characterized by making the coating surface of a sample face the bottom of the coating chamber, so that the sticking particles on side walls of the coating chamber will not fall on the coating surface of the sample during the coating process, thereby a smooth coating layer can be formed on the coating surface of the sample after the coating process is finished.

Abstract: A semiconductor device and method of manufacture are provided. In some embodiments isolation regions are formed by modifying a dielectric material of a dielectric layer such that a first portion of the dielectric layer is more readily removed by an etching process than a second portion of the dielectric layer. The modifying of the dielectric material facilitates subsequent processing steps that allow for the tuning of a profile of the isolation regions to a desired geometry based on the different material properties of the modified dielectric material.

Abstract: A circuit board heat dissipation system includes circuit board unit that includes a motherboard and a daughterboard, a base seat, and a fastening unit that includes a plurality of first and second fastening components. Each first fastening component extends through the daughterboard and is engaged with the base seat. Each second fastening component includes a long fastener that extends through the base seat and the daughterboard and that is engaged with the motherboard, and a flat washer and a resilient member that are sleeved on the long fastener. The resilient member is disposed between a head portion of the long fastener and the flat washer for biasing the base seat and the daughterboard against the motherboard.

Abstract: A heat dissipation device includes a heat conducting plate and a heat sink. The heat conducting plate has a first surface and a second surface opposite to each other. The heat sink is coupled to the first surface of the heat conducting plate. The heat sink includes a first peak portion, a second peak portion, a valley portion and a first curved surface. The first peak portion and the second peak portion are adjacent to each other. The valley portion is located between the first peak portion and the second peak portion. The first curved surface is coupled between the first peak portion and the valley portion. An extension line perpendicular to a corresponding tangent line of the first curved surface passes between the first peak portion and the second peak portion.

Abstract: A method of manufacturing a heat dissipating device includes steps of providing a base, wherein the base includes a clamping portion, a supporting portion and two side portions, the clamping portion is arc-shaped, a first recess structure is formed on an outer surface toward an inner surface of each side portion, the two side portions connect the clamping portion and the supporting portion, and an accommodating space is formed between the clamping portion, the supporting portion and the two side portions; disposing a first end of a heat pipe in the accommodating space, wherein the first end is supported on the supporting portion; and punching the clamping portion toward the supporting portion such that the clamping portion cooperates with the supporting portion to clamp the first end in a tight-fitting manner, wherein the clamping portion is capable of deforming through the first recess structure during punch processing.

Abstract: A parallelepiped tape cutter includes a cover comprising a top, two sides, a bottom flange, a blade at an open end of one side, a latching element on the other side, a concave member on an inner surface of the latching element, and a limit member on an inner surface of the other side adjacent to one end of the concave member; a support comprising a recessed rail on either side of a raised bottom, a bent first wall, a bent second wall separate from the first wall, a latch projecting out of one end of the second wall toward the first wall, the latch having a laterally protruded latching end proximate to one end of the first wall, a slit at the other end of the first wall, and an opening defined between the second wall and the slit; and a tape roll in the support.

Abstract: A tape cutter blade has truncated trapezoidal sharpened teeth and a substantially triangular gap is formed between any two adjacent teeth. The sharpened teeth are capable of leaving uniform teeth on the severed end of a cut out portion of an adhesive tape after application of the tape. This has the benefits of being visually attractive, easy of applying the adhesive side of the tape onto an object to be sealed, and capable of cutting out adhesive tapes formed of foam or fiber.

Abstract: An adhesive tape cutter comprising a pair of protecting portions formed in pair at the right and left sides for fitting and cutting an adhesive tape roll. The top of the protecting portions includes a tape-guiding slot and a tape-attaching portion while a slide slot portion is formed at a side wall of the protecting portions. The slide cap is fitted with a cutting edge, and the slide cap further includes a sliding piece that fits into the slide slot portion in such a manner that a proper sliding action is achieved. An elastic supporting piece is integrally formed within a tape-receiving space defined by the protecting portions such that that the elastic supporting piece can be pushed against the adhesive tape roll at any time. In this way, a certain clamping relationship between the adhesive tape roll and the protecting portions is constantly maintained.

Abstract: An adhesive tape cutter includes a pair of fastening portions at the right and left sides such that both sides of an adhesive tape roll are enclosed by the fastening portions. The top of the fastening portions is fitted with an inclined resilient tongue and formed with a tape-guiding slot. A slide slot is formed in the side wall of the fastening portions in which a slider of a slide cap fits in such a way that a proper sliding action is achieved. Moreover, a plurality of resilient supports are integrally formed in a tape-receiving cavity defined by both of the fastening portions such that an adhesive tape roll may be constantly pushed by the resilient supports for creating a certain clamping relationship between the adhesive tape roll and the fastening portions.

Abstract: This invention relates to a method of licensing computer program or data to run or use, and more specifically, using a network transmission protocol to license program or data. This method is to store (embed) register number entered in client side into computer storage, and when the client-side is to execute/use the program or data, the register number is automatically read (fetched) and transmitted to server side through network after encrypting for authorization. Besides identifying the validity, the server also judge whether there are same register numbers to apply for certification at the same time from another client side. If there is not error, the program or data is permitted to execute/use in client side. Otherwise, only partial functions are permitted to use or no functions can be used. So, one method that can ensure program or data to be used legally is provided.
