  • Patent number: 12287602
    Abstract: A developing cartridge includes: a cartridge body for accommodating developers; a driving part at a first end in a first direction; a developing roller rotatable about a rotation axis extending along the first direction and positioned at a third end in a second direction; a storage medium for storing information; an electrical contact surface electrically connected to the storage medium and fixed relative to the cartridge body, and a lifting element configured to lift up the cartridge body in the third direction. The electrical contact surface is positioned at the first end in the first direction and is farther away from the developing roller relative to the driving part. The lifting element is farther away from the developing roller in the second direction away from the driving part.

  • Patent number: 6914396
    Abstract: A high-current, high-gradient, high-efficiency, multi-stage cavity cyclotron resonance accelerator (MCCRA) provides energy gains of over 50 MeV/stage, at an acceleration gradient that exceeds 20 MeV/m, in room temperature cavities. The multi-stage cavity cyclotron resonance accelerator includes a charged particle source, a plurality of end-to-end rotating mode room-temperature cavities, and a solenoid coil. The solenoid coil encompasses the cavities and provides a substantially uniform magnetic field that threads through the cavities. Specifically, the MCCRA is provided with a constant magnetic field sufficient to produce a cyclotron frequency a little higher than the RF of the accelerating electric field. A plurality of input feeds, each of which respectively coupled to a cavity, are also provided. According to an embodiment of the invention, the beam from the first cavity passes through a cutoff drift tube and is accelerated further with a cavity supporting a still lower radio-frequency electric field.
