  • Lopper shear with an improved structure
    Patent number: 7059021
    Abstract: A lopper shear pull-rope grip includes a closed end provided with a bulge. The through hole of the bulge is connected to the hollow notch of the grip, where a rope can penetrate the through hole. And, a slanting board extends downwards from the through hole. The slanting board is provided with a conductive rim. Moreover, a through notch is formed in the grip under the bulge. A pulley is mounted in the through notch and has a rim. Thus, the pulley can slide smoothly along the slanting board of the grip. When the rope is pulled upwards, the pulley will clamp the rope more compactly so as to adjust and position the rope rapidly for convenient and loose-free usage.

  • Method for manufacturing organic light-emitting diodes
    Patent number: 7048603
    Abstract: A method for manufacturing organic light-emitting diodes (OLEDs) is disclosed, by adding nitrogen (N2) into the material of a hole transport layer (HTL) and evaporating the nitrogen and the material of the hole transport layer while growing the hole transport layer, so as to dope nitrogen molecules into the hole transport layer. In the hole transport layer, the nitrogen molecules are impurities of higher energy level, and are used to catch holes while the holes transports and trap the holes in the hole transport layer, thereby obtaining an object of improving the luminance efficiency of the organic light-emitting diodes with lower cost.

  • Matrix board to board connector assembly
    Patent number: 7044765
    Abstract: A matrix board to board connector assembly includes a first connector and a second connector. A first locking piece is provided and fixed on the first connector. The first locking piece has a locking portion bend from a lower edge thereof and extending sideward and outward. A second locking piece is provided with an elastic portion and fixed on the second connector. The elastic portion is configured to provide a spring end. The spring end is firstly protruded and then concaved at its free end. During mating of the first and the second connectors, the spring end is firstly deflected and then elastically recovered to hit on the locking portion with a click to insure that the first and the second connectors have been properly mated.

  • Shield and electrical connector with the shield
    Patent number: 7044792
    Abstract: The present invention discloses a shield and an electrical connector with the shield. The shield has elastic slices each having a first bending portion, a second bending portion and a pressing portion. The first bending portion has a first horizontal portion flexed horizontally and outwardly, a first vertical portion flexed vertically and downwardly and a first corner connecting therebetween. The second bending portion has a second horizontal portion flexed horizontally and outwardly, a second vertical portion flexed vertically and upwardly and a second corner connecting therebetween. The pressing portion is extended from the upper part of the second vertical portion. When the electrical connector is assembled with an outside electrical device, the pressing portions of the elastic slices prop against the outside electrical device.

  • High specific surface area composite alumina powder with thermal resistance and method for producing the same
    Publication number: 20060099421
    Abstract: A composite alumina powder with thermal resistance and high specific surface area and a method for producing the same are disclosed. The composite alumina powder is mixed with multi-phase alumina powders for raising the temperature of phase transformation, so as to maintain its high specific surface area when suffering high temperatures for a long time. Therefore, as the composite alumina powder of the present invention is applied as a high temperature catalytic material, it provides high specific surface area required of the catalysis, prolongs its lifetime, and reduces the amounts of noble metals used as well, resulting in great reduction of cost.

  • Unit selection module and method for Chinese text-to-speech synthesis
    Publication number: 20060095264
    Abstract: This invention relates to a unit selection module for Chinese Text-to-Speech (TTS) synthesis, mainly comprising a probabilistic context free grammar (PCFG) parser, a latent semantic indexing (LSI) module, and a modified variable-length unit selection scheme; any Chinese sentence is firstly input and then parsed into a context-free grammar (CFG) by the PCFG parser; wherein there are several possible CFGs for every Chinese sentence, and the CFG (or the syntactic structure) with the highest probability is then taken as the best CFG (or the syntactic structure) of the Chinese sentence; the LSI module is then used to calculate the structural distance between all the candidate synthesis units and the target unit in a corpus; through the modified variable-length unit selection scheme, tagged with the dynamic programming algorithm, the units are searched to find the best synthesis unit concatenation sequence.
