  • Patent number: 10578310
    Abstract: A cooking apparatus includes a body, an input unit configured to receive a command in relation to controlling the cooking apparatus from a user, a knob configured to be attachable to one surface of the body or detachable from the body, and a controller configured to sense whether the knob is attached to the body, to receive the command via the knob when the knob is attached, and to receive the command from the input unit when the knob is not attached. As is apparent from the above description, the cooking apparatus may be controlled according to a user's preferences by using the knob attachable to and detachable from the body of the cooking apparatus and may be more conveniently controlled by using the knob in several sides of the cooking apparatus rather than a limited space.

  • Patent number: 7938898
    Abstract: Provided is an ink composition including a colorant; a solvent; a surfactant; and an oxygen absorber of a hetero ring compound and a hydroxylamine-based compound. The oxygen absorber lowers a concentration of oxygen dissolved in the ink composition and maintains a low level even when the ink composition is in a high-temperature condition. Thus, gas is substantially not generated and bubbles are not formed. The ink composition can be stably ejected during high-speed printing.
