  • Patent number: 12001156
    Abstract: In some examples, a developing device includes a developing container including an opening and to store a developer, a developing sleeve installed in the developing container and partially exposed to an outside of the developing container through the opening, a regulation member upstream of the opening in a rotation direction of the developing sleeve and to regulate an amount of the developer adhered to the developing sleeve and supplied to the opening, and a magnetic member inside the developing sleeve. The magnetic member includes a main pole facing the opening, a regulation pole facing the regulation member, and a catch pole upstream of the regulation pole in the rotation direction of the developing sleeve. The magnetic member is to cause adhesion of the developer in the developing container to the developing sleeve.

  • Publication number: 20190139454
    Abstract: An operation training apparatus is used in training for operations on living tissue that expands and contracts. The apparatus includes a model body, which mimics the living tissue, a driving device, which moves the model body in a manner mimicking the expansion-contraction, and a controller, which controls a manner in which the driving device is driven. The driving device includes an electroactive polymer actuator.

  • Patent number: 9448429
    Abstract: Disclosed is a method for fabricating a lightweight and thin liquid crystal display (LCD) device, using a supplementary substrate for processing of a thin glass substrate. Inactive gas is sprayed onto the surface of the substrate to thus remove OH groups from the surface, before the thin glass substrate and the supplementary substrate are attached to each other. Under such configuration, the supplementary substrate can be easily separated from a completed liquid crystal panel which is in an attached cell state, without any damages.

  • Patent number: 7822720
    Abstract: A method and a system of detecting a keyword whose input number is rapidly increased in real time which can estimate a search number at a future point in time by reflecting an input trend of the keyword in real time at a present point in time and can immediately detect the keyword whose input number is rapidly increased according to a criterion value calculated by the estimated search number. Specifically, the method and system of detecting a keyword whose input number is rapidly increased in real time which can estimate the search number for each keyword at the future point in time in real time and can immediately detect the keyword whose input number is rapidly increased according to a criterion value calculated by the estimated search number.
