摘要： A water pipe wrench structure consisting of a first wrench body and a second wrench body pin jointed by a control component. The first wrench body includes an actuating piece. A tooth space is positioned on this actuating piece. This actuating piece and a tooth piece extend with a uniform curvature. The second wrench body includes a perforation to pass the control component through this perforation and the tooth space. This control component includes a column piece and a grinding tooth piece, and the grinding tooth piece can be moved by pressure, so that the grinding tooth piece can be engaged to or separated from the tooth space and thus end the movement of the control component.

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： Snap ring pliers include two levers, two posts, and two protruding blocks. The two levers are pivotally connected to each other and relatively pivotable. The two levers each have a control end at a distal end thereof. The two posts are fixed to the control ends of the two levers, respectively. The posts each have a complete surface without a notch. The posts each have a non-circular cross-section and at least one an arris for leaning against a perforation of a snap ring. The two protruding blocks are respectively fixed to distal ends of the two posts for restraining the snap ring from being separated from the posts, thereby controlling the snap ring stably.

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 pliers has guiding surfaces at tooth portions of the first pliers body and tooth portions of the engaging unit of the control member. Therefore, when the pressing block of the control member is not pressed, even if the first pliers body is engaged with the tooth portions of the engaging unit, the second pliers body can still be pushed forward relative to the first pliers body, so that the second guiding surfaces of the second tooth portions of the engaging unit slide relative to the first guiding surfaces of the first tooth portions and each of the first tooth portions is moved to engage with a next corresponding second tooth portion, thereby allowing the second pliers portion being movable toward the first pliers portion. Hence, the clamping distance of the pliers can be adjusted to match with an object to be clamped.

The switch circuit may include a first transistor having a source terminal to accept an input signal, a drain terminal to provide an output signal, and a gate; a power supply providing a gate voltage. The switch circuit may also include a circuit to couple a switch signal to the gate, wherein the circuit turns the first transistor ‘off’ for all values of the input signal when the switch signal is ‘low.’ A programmable gain amplifier (PGA) is also provided. The PGA may include an input stage having an input node to couple an input signal, and an output node to provide a gate signal, at least a first gain stage including a resistor and a switch circuit as above. A differential gain amplifier may be included to provide an output signal from the gain signal.

摘要： Pliers with a restoring function include an elastic element and two pliers bodies. The elastic element has two urging ends. The two pliers bodies have two pinching heads, two handles, and two pivotal parts. Each of the pivotal parts has a recess and a pivotal hole. A pivotal element goes through the two pivotal holes. The elastic element is disposed in the two recesses and penetrated by the pivotal element. Both urging ends of the elastic element are on opposite sides of the two recesses to urge sidewalls of the recesses, thereby opening the pliers. A buffer region is designed in each of the recesses for the corresponding urging end. When the opening angle of the pliers is greater than that is supported by the elastic element, at least one urging end of the elastic element releases its urging against the recess sidewall and moves in the buffer region. The pliers become relaxed then.
