Abstract: A slide rail assembly includes a first rail with a positioning structure, a second rail displaceable relative to the first rail and providing a concave surface on the back to face the positioning structure, a first stopper pivotally connected to the concave surface corresponding to the first side of the positioning structure, and an operating member movably connected to the second rail and placed on the concave surface so that the operating member is on the side of the first stopper. The slide rail assembly can be installed on the side of the carrier, which can be a server case or drawer, or can be used on servers or furniture.

Abstract: A method and a device for battery detection are provided. In the method, multiple characteristic values measured from a battery during operation of the battery are captured via a data capturing device to form a characteristic curve. Curve fitting is performed on the characteristic curve to obtain a curve error. According to the magnitude of the curve error, it is determined whether the battery is normal. When the determination result is abnormal, a step-curvature radius analysis is performed on the characteristic curve to determine whether the battery is normal.

Abstract: A double-lobe type rotor design process includes a process for forming a defined rotor and a process for forming a conjugate rotor, wherein the defined rotor and the conjugate rotor intermesh and conjugate to each other. The rotor profile curves suitably for the completed operation period of carryover, suction and exhaust could be well defined by proper parameters, thereby optimizing rotor performance, enhancing compression ratio, providing a smooth suction and exhaust process and avoiding noise and vibration.

Abstract: The present invention provides a slurry expressing and liquid displacing device which is used to express slurry and then separate out effluence and solid of the slurry through radial pore volume displacement of continuous filtration and washing for getting high purity solid. The slurry expressing and liquid displacing device includes a expressing mechanism, a displacing mechanism, a blender, a collecting tube, and first and second storage troughs. The expressing mechanism includes a first helical transmission shaft having a compression zone for transporting and efficiently compressing the slurry. The displacing mechanism includes a second helical transmission shaft rotatably connected with the first helical transmission for connecting with displacing liquid such as water. A plurality of through holes is disposed at the side surface of the second helical transmission shaft to radially spray through for facilitating the displacing liquid to flow out therethrough.

Abstract: An inductive charger is adapted for a portable electrical devices or information products and connects with a rectifier for charging. The inductive charger includes a hollow carrier, at least a coil surrounding an outer surface of the carrier, fixed magnets and at least a sliding magnet. The carrier has a pair of end portions opposite to each other, and the fixed magnets are respectively located on the end portions of the carrier. N poles and S poles of the fixed magnets are oriented coincident with each other. The sliding magnet is located between the fixed magnets, and N pole and S pole of the sliding magnet is opposing to N poles and S poles of the fixed magnets. When the carrier is driven, the sliding magnet moves back and forth between the fixed magnets due to magnetic repulsion of the sliding magnet, which changes flux of the coil thereby producing induced electromotive force.

Abstract: A pump includes a body, and first and second rotors. A chamber is defined in the body. First and second inlets and first and second outlets are defined in the body in communication with the chamber. The first rotor is rotatably received in the chamber and connected with a first shaft. The first rotor is generally circular with a blade extending outward therefrom. The blade includes first and second mating surfaces. A third mating surface is formed at the blade between the first and second mating surfaces. The second rotor is rotatably received in the chamber and connected with a second shaft. The second rotor is generally circular with an engaged recess inward defined therein for mating with the blade of the first rotor. The engaged recess includes first and second engaged surfaces for mating with the first and second mating surfaces. A third engaged surface is formed at the bottom of the engaged recess between the first and second engaged surfaces for mating with the third mating surface of the blade.
