Abstract: Disclosed are a gas purification device, and an apparatus and a method for measuring isotopes of noble gases. The gas purification device includes a housing and a purification mechanism. The housing is provided with a reaction chamber. The reaction chamber is in a vacuum state and is configured to hold a gas sample. The purification mechanism is arranged on the housing and is provided with a cavity. The cavity in the purification mechanism is communicated with the reaction chamber. The purification mechanism is configured to purify the gas sample in the reaction chamber to obtain a purified gas.

Abstract: A system for on-line measuring the thickness of a continuous casting billet and adjusting a rolling reduction amount, is capable of giving an accurate, constant and rapid feedback on the thickness of the billet in the continuous casting process online, avoiding the deviation of the rolling reduction amount of the billet in the continuous casting production process which is triggered by the factors such as the capacity of the continuous casting equipment, the execution deviation of the rolling reduction process, the metal solidification attribute such as non-preset expansion and contraction, so as to maximize the function of the continuous casting rolling reduction and improve the solidification quality of the billet.

Abstract: An anti-interference temperature signal receiving device and signal processing method. The device comprises a digital signal processing chip, a transmitting phase-locked loop local oscillator, a fixed intermediate frequency oscillator, a first mixer, a first band-pass filter, a power amplifier, a transceiver module, a second band-pass filter, a low noise amplifier, a receiving phase-locked loop local oscillator, a second mixer, a receiving intermediate frequency filter, a second receiving local oscillator, a third mixer, and a power supply circuit. Because a first intermediate signal, has a frequency consistent with the reference signal frequency, it can be ensured that transmitting and receiving are performed at an identical frequency, while resolving a signal interference problem owing to a phase-locked loop characteristic and resulting in identical signal frequencies of a transmitting signal and a reference signal during synchronization.

Abstract: An electromagnetic transducer is disclosed in the present invention. The electromagnetic transducer includes a frame comprising a receiving space, an upper surface and a lower surface opposite to the upper surface; a suspension including a suspending ring facing the receiving space and at least one pair of elastic arms with projections thereof disposed in an outline of the frame, wherein each of the elastic arms includes a fixing portion mounted on the lower surface and an vibration portion connected with the fixing portion, spaced from the lower surface and providing an vibration approaching and away from the lower surface; a magnetic circuit unit surrounded by the suspending ring for being elastically supported by the suspending ring in the receiving space; and an vibration unit assembled with the frame and facing the magnetic circuit unit.

Abstract: A fast-response horizontal vibration micro motor that includes a housing, a cover plate, a vibration assembly and coils. The cover plate is installed on the housing; the vibration assembly is suspended in the installation space; the coils are located at positions a certain distance above the vibration assembly; the vibration assembly can perform reciprocating vibration in a direction substantially parallel to the bottom surface of the housing, and also enables the two elastic supporting members located on the two opposite sidewalls to be correspondingly stretched and compressed during vibration; the vibration assembly includes a vibration block, and the vibration block is provided with at least three installation through holes and permanent magnets installed in the installation through holes. The arrangement of the three permanent magnets increases the response speed of the motor, and the arrangement of the two serially-connected coils also increases the response speed of the motor.
