    摘要: A high purity aqueous solution of hydroxylamine product is prepared by treating an aqueous solution of hydroxylammonium salt with a base like ammonia at low temperatures. A novel process can be carried out by separating the ammonium salt side product from hydroxylamine with a low temperature filtration and a resin-exchange process. The concentration of the hydroxylamine product is further improved by a safe distillation process that produces a high purity and high concentration hydroxylamine product with reduced risks of explosion.

    摘要: A tool structure including two grips and a tool head. By way of an opening of a first pivot section of the grip, the first pivot sections of the grips can be separated, permitting the grips to be folded to two sides of the tool head. This reduces the room occupied by the tool and facilitates storage and carriage of the tool. The first pivot sections of the grips are spaced from the second pivot sections of the tool head by a certain distance to form a double-lever structure and prolong the length of the force application arm so as to save strength.

    摘要: A tool includes two grips and at least one tool head. The grips can be opened to different extents so as to rotate the fixing pins of the grips relative to the openings of the tool head. Accordingly, the short sides of the fixing pins can be respectively aligned with the openings to permit the detachment of the grips from the tool head. Otherwise, the grips are stopped by the long sides of the fixing, pins from detaching from the tool head. The grips can be easily and quickly assembled with or disassembled from the tool head. In addition, the replacement of the tool head can be performed by hand without using any tool or switch. Also, the tool has fewer components which are not easy to miss.

    摘要: The circuit board with a heat dissipating structure is provided. A first grounding conductor layer is formed on a first surface of a substrate. A first insulting layer is formed on the first grounding conductor layer and defines a number of circuit element pin openings and a plurality of heat dissipating openings therein so that the first grounding conductor layer is exposed from the circuit element pin openings and the heat dissipating openings. A number of solder balls are disposed in the circuit element pin openings and contacted with the first grounding conductor layer. A number of heat dissipating structures are disposed in the heat dissipating openings and contacted with the first grounding conductor layer. The heat dissipating structures and the solder balls have an identical material. The method for manufacturing the circuit board is also provided.
