  • Publication number: 20240079278
    Abstract: A method includes forming a pad layer. The pad layer includes a first portion over a first part of a semiconductor substrate, and a second portion over a second part of the semiconductor substrate. The first portion has a first thickness, and the second portion has a second thickness smaller than the first thickness. The semiconductor substrate is then annealed to form a first oxide layer over the first part of the semiconductor substrate, and a second oxide layer over the second part of the semiconductor substrate. The pad layer, the first oxide layer, and the second oxide layer are removed. A semiconductor layer is epitaxially grown over and contacting the first part and the second part of the semiconductor substrate.

  • Patent number: 11048190
    Abstract: A leak-prohibiting device includes a fixation mount for being mounted to an toner outlet of a housing of a toner cartridge, a valve member mounted in the fixation mount and forced by a first resilient member to seal an opening of the fixation mount, and a push member mounted in the fixation mount and moveable between an extended position where the push member is abutted against the valve member and a retracted position where an engagement portion of the push member is engaged with a position-limiting portion of the fixation mount such that the push member, on which a biasing force of a second resilient member exerts toward the extended position, is prohibited from moving from the retracted position to the extended position. As such, the leak-prohibiting device can positively block the toner cartridge and the toner cartridge can be repeatedly installed with less manual force.

  • Patent number: 10379491
    Abstract: A lateral cap of a process cartridge includes a main body, a through hole, a flange and a guiding portion. The main body has a first side for being disposed to a housing of a process cartridge, and a second side opposite to the first side. The through hole penetrates through the first and second sides. The flange extends from the second side of the main body toward a direction away from the first side. The guiding portion extends from the flange toward an axis direction of the through hole. The lateral cap guides a rotational force receiving member to a desired position and can guide the rotational force receiving member to move toward a driving head to make them firmly coupled with each other when the rotational force receiving member is moved from a biased position to a coaxial position in alignment with the driving head.

  • Patent number: 9671721
    Abstract: A toner cartridge includes a shell, a sleeve and a knocking block. The shell has an internal space, an opening communicating with the internal space and exterior of the shell, and an imaginary axis. The shell is rotatable about the imaginary axis. The sleeve is disposed at an outside of the shell and includes an internal path extended along an imaginary line not parallel to the imaginary axis, and two stopping portions located at two ends of the internal path. The knocking block is accommodated in the internal path, and movable along the internal path to knock the stopping portion when the shell rotates, so as to vibrate the shell, so that the carbon powder sticking on the inner wall of the toner cartridge can be shaken off and then discharged by the toner cartridge. Therefore, the remnant carbon powder in the toner cartridge is effectively decreased.
