    摘要: A meander embedding sector traveling-wave antenna for series superconducting detectors is provided, including: a detector array, a meander metal layer, a pair of bend-line metal layers, and a pair of sector metal layers. The detector array is individually connected in the meander metal layer and the pair of bend-line metal layers; the pair of bend-line metal layers is correspondingly connected to the pair of sector metal layers; and the pair of sector metal layers is disposed symmetrically centered on the detector array. The antenna improves working bandwidth of THz antenna and completes low-impedance matching between a single antenna and each series Josephson junction embedded in the antenna. The embedding meander can be connected to a plurality of low-impedance detectors, and performance of the antenna is not influenced while target impedance matching is completed. And the working bandwidth of the THz antenna embedded with the series detectors is increased.

    摘要: A fully-automated sushi making apparatus, comprising a fixed plate (1), a container module (2), an annular shielding module (3), a center shielding module (4), a dispensing module (7), a ring-shaped isolation module (5), a cylindrical pushing module (6), an extraction module (8), a recovery module (9), and a controller (10). The controller controls vertical drive units (52, 62, 81) and horizontal drive units (31, 41, 51, and 61) to drive the connected annular shielding module, ring-shaped isolation module, and cylindrical pushing module to perform layerwise removal of rice from the container module, then drives the center shielding module, the dispensing module, and the cylindrical pushing module to add sushi ingredients into the hollow center of the rice removed from the container module, and finally drives the extraction module, the annular shielding module, and the center shielding module to move in unison to extract the completed sushi.

    摘要: A composite motor having high-precision positioning, comprising: a housing (1), a rough positioning assembly, a hollow output shaft (2), a fine positioning assembly, a power switching apparatus and a controller (6). A stepper motor (3) in the rough positioning assembly is responsible for rough positioning of the composite motor, an annular travelling wave ultrasonic motor in the fine positioning assembly is responsible for tail end fine positioning of the composite motor, and the controller (6) implements power output switching between the annular travelling wave ultrasonic motor and the stepper motor (3). The composite motor effectively solves the problem that annular travelling wave ultrasonic motors which operate continuously for a long time have a short service life, and ensures high-precision positioning while also extending motor service life.
