Proposed is a fuel cell stack including a plurality of fuel cell units having a truncated cone shape and connected in series with each other. The series connection of the fuel cell units is made such that a relatively small outer diameter portion of one of the fuel cell units is inserted into a relatively large outer diameter portion of another fuel cell unit adjacent to the former fuel cell unit.

This invention provides a three-dimensional full-focusing ultrasound imaging method based on a frequency-wavenumber domain row-column addressable array, belonging to the field of three-dimensional full-focusing ultrasound. The method includes the following steps: using a row-column addressable array with a total of N+N transmitting elements to perform ultrasonic scanning on a medium to obtain acquired signals; based on the acquired signals, performing spatial sampling to obtain a three-dimensional voxel network; using a frequency-wavenumber domain method to beamform the radio frequency data corresponding to the three-dimensional voxel network; and performing envelope processing on the beamformed data to form a three-dimensional image. This invention's beamforming method for three-dimensional full-focusing ultrasound imaging based on a frequency-wavenumber domain row-column addressable array significantly reduces the number of elements and beamforming channels required for three-dimensional imaging by using a row-column addressable array, while providing a larger imaging area. The imaging process employs full-matrix capture to obtain high-resolution images, and the frequency-wavenumber domain beamforming method significantly shortens the imaging time.

The utility model discloses a kind of tin nozzle automatic cleaning device and selective wave crest welding equipment, it is related to selective wave crest welding equipment technical field.The tin nozzle automatic cleaning device includes: cleaning liquid storage tank, flow control valve and cleaning liquid jet pipe.The cleaning liquid storage tank is used to store cleaning liquid;The flow control valve is communicated with the cleaning liquid storage tank, wherein the flow control valve is communicated with the selective wave crest welding equipment, and is configured to when the selective wave crest welding equipment is in tin wave height reduction state, the flow control valve starts;The cleaning liquid jet pipe is connected with the flow control valve, and the end of the cleaning liquid jet pipe is provided with cleaning liquid nozzle, wherein the opening direction of the cleaning liquid nozzle is vertically downward and can be opposite to the tin nozzle.By using the technology provided by the utility model, the problem that tin nozzle surface damage is easily caused by long-term brushing tin nozzle can be effectively solved.

There is provided a technique installing a memory on a developing cartridge and a drum cartridge, and capable of reducing the number of components in the developing cartridge. A drum cartridge 2 includes a first memory 71 having a first electrical contact surface, and an elastic member 300 that can expand and contract in a second direction. A developing cartridge 1 includes a second memory 81 having a second electrical contact surface, and a developing holder 82 holding the second electrical contact surface such that the second electrical contact surface is movable relative to a casing 10. The developing holder 82 is connected to the elastic member 300 and is movable in the second direction in a state where the developing cartridge 1 is attached to a drum frame 40. Accordingly, wear of the second electrical contact surface is restrained. Also, since an elastic member need not be provided in the developing holder 82, the number of components in the developing cartridge 1 can be reduced.

The invention relates to the technical field of batteries, and discloses a battery circuit breaking unit and a battery pack, the battery circuit breaking unit comprises a first terminal, a second terminal, a third terminal, a first movable contact plate, a second movable contact plate and a driving assembly; every two of the first terminal, the second terminal and the third terminal are mutually spaced; the first movable contact plate can make contact with or break away from the first terminal and the third terminal. The second movable contact plate can make contact with or break away from the second terminal and the third terminal. The driving assembly is connected with the first movable contact plate and the second movable contact plate and is configured to drive the first movable contact plate and the second movable contact plate to move; when one of the first movable contact plate and the second movable contact plate makes contact motion, the other one makes separation motion; the first movable contact plate and the second movable contact plate are arranged and share the third terminal and the driving assembly, so that light weight and cost reduction of the battery pack are facilitated.
