Abstract:
A laminate circuit board structure from button up including a substrate, a circuit metal layer, a nanometer plating layer and a cover layer is disclosed. The nanometer plating layer is smooth a thickness of 5-40 nm, and can be directly forming on the outer surface of the circuit metal layer or manufactured by firstly forming the nanometer plating layer on a preforming substrate, then pressing the substrate against the nanometer plating layer, and finally removing the preforming substrate. The junction adhesion between the nanometer plating layer and the cover layer or the substrate is improved by chemical bonding. Therefore it does not need to roughen the circuit metal layer or reserve circuit width for compensation such that the density of the circuit increases and much more dense circuit can be implemented in the substrate with the same area.
Abstract:
A LED package structure having an electro-static protective diode, the structure is disclosed. The structure comprises: an electro-static protective diode having an n-type electrode mounted on a lampstand by a conductive paste layer, so that it forms an electrical connecting with a positive leadfame. A LED having a p-type and an n-type electrode positioned on one side and a bottom on the other side of the LED mounted by an insulating layer atop the p-type electrode of the electro-static protective diode. Next a first conductive wire connects between the p-type electrode of the LED and the positive leadframe. A second conductive wire, connects the n-type electrode of the LED with the negative leadframe. A third conductive wire connects the p-type electrode of the electro-static protection diode to the negative electrode of the leadframe. Transparent resin is finally used to form a dome-shaped package.
Abstract:
A method of manufacturing a laminate circuit board is disclosed. The method includes forming a metal layer on a substrate, patterning the metal layer to form a circuit metal layer, forming a nanometer plating layer with a thickness of 5 to 40 nm over the circuit metal layer, and forming a cover layer covering the substrate and the nanometer plating layer with improved adhesion by chemical bonding to form the laminate circuit board. Another method includes forming the circuit metal layer and the nanometer plating layer on a preforming substrate, pressing the preforming substrate against a substrate to push the circuit metal layer and the nanometer plating layer into the substrate, and removing the preforming substrate. By the present invention, the density of circuit is increased and much denser circuit can be implemented on the substrate with the same area.

Abstract:
Systems, computer-program-products, and methods for managing terminal services (TS) accounts and sessions for online utilization of hosted applications are provided. A system is operative to monitor a supply of available TS accounts and create TS accounts in response to detecting that the supply of available TS accounts is below a minimum number. When a request to access a TS session is detected, the system provisions a TS account for the user to immediately access the TS session without entering credentials. The provisioned TS account provides access and is associated with a unique profile. The system is also operative to receive the request to access the hosted application and decrypt credentials generated for the user. A method involves reading a username assigned to a user requesting access, locating the TS account associated with the username, identifying the language associated with the TS account, and launching the hosted application in that language.
Abstract:
A golf club head includes a golf club head body and a complex plate. The golf club head body includes an assembling opening to mount the complex plate. The complex plate includes a base plate and a protrusion structure which are made of different metal material. The upraised protrusion structure has a buffer structure formed therein. The complex plate has an outer (front) surface and an inner (rear) surface opposite to the outer surface. The protrusion structure is disposed on the inner surface of the complex plate. In assembling operation, the complex plate is received in the assembling opening of the golf club head body so as to constitute the golf club head.

Abstract:
Computing systems can be dynamically configured, allocated, and deployed based on user requirements. For example, a user can request a number of servers for dynamic configuration, allocation, and deployment. Embodiments provide a quick and efficient way for users to test code and programs, debug code and programs, and/or perform other configuration and testing operations using one or more computing systems, such as a cluster of servers. Reserved systems are dynamically configured with necessary code and/or content according to user requirements. The reserved cluster of systems can be returned to an available pool once a reservation expires, allowing the returned systems to be used for a subsequent reservation.
