Abstract: A structure for fixing a permanent magnet in a rotor core. The structure includes a magnet accommodation portion into which a permanent magnet is to be inserted, an internal hole formed in an area adjacent to one end of the magnet accommodation portion, a pressing portion provided between the magnet accommodation portion and the internal hole. The pressing portion forms a convex shape toward the permanent magnet to be in contact with the permanent magnet.

Abstract: A motor core assembly and a manufacturing method for the motor core assembly include a permanent magnet inside a motor that may be recovered, in its original state without damage and at a low cost, from a motor to be disposed of together with a device when the device to which the motor is applied is disposed of in a state in which the permanent magnet wrapped with an injection part is inserted into a rotor core. Accordingly, the number of manufacturing processes and the cost may be reduced.

Abstract: A tangential flow filtration module includes plural plate units connected in sequence. Each of the plate units includes a main body, a first combing portion, a second combing portion, a first flange and a second flange. The main body has a first side surface, a second side surface and a through hole. The first side surface is opposite to the second side surface, and the through hole extends from the first side surface to the second side surface. The first combing portion and the second combing portion are disposed on the first side surface and the second side surface respectively. The first flange and the second flange respectively protrude from the first side surface and the second side surface and respectively. The first combing portion of one of the plate units is combined with the second combing portion of another one of the plate units, so that a sieving structure.

Abstract: A biological energy signal acquisition and conversion device comprises: a signal acquisition module, enhancing a biological energy signal generated by an original biological energy body, and extracting the signal; a signal processing module, receiving the extracted original biological energy signal and filtering and amplifying the signal, and generating an output energy signal; and a signal output unit, being able to enhance an output function in cooperation with a magnetic substance, and output the energy signal to a biological energy carrier. By shortening the distance between the original biological energy body and a signal receiving unit, and using the magnetic substance to excite the original biological energy body, the strength of the received extracted original biological energy signal is enhanced, and the noise proportion is greatly reduced, reducing the technical complexity and costs for back-end signal processing, and improving the effect of a biological energy signal.

Abstract: An electroluminescent display device includes a display panel including a plurality of pixels connected to a plurality of sensing lines, a plurality of sampling circuits configured to simultaneously sample driving characteristics of the pixels to generate sampling outputs, a plurality of sampling multiplexers configured to divide the sampling outputs into n groups and to alternately select group sampling outputs, a plurality of scalers individually connected to the sampling multiplexers, and a global multiplexer configured to selectively connect outputs of the scalers to an analog-to-digital conversion circuit, wherein the number of scalers is less than the number of sampling circuits.

Abstract: An interior permanent magnet electric motor forms a buried angle of a left permanent magnet of a slot part of a rotor differently from a buried angle of a right permanent magnet of the slot part of the rotor, so as to reduce torque ripple while sufficiently maintaining motor efficiency as compared to an I-type rotor to effectively improve noise, vibration, and harshness performance.
