  • Publication number: 20220082169
    Abstract: A steam valve having a first inclined surface, which is formed at the distal end portion of a valve rod and in which the outer diameter of the valve rod increases from the distal end toward the base end of the valve rod, and a second inclined surface, which is formed on the inside of a portion of a main valve that is positioned on the base-end side of the valve rod and which inclines with the same inclination angle as the first inclined surface. In a state in which a slave valve and the main valve are closed the first inclined surface and the second inclined surface are separated from each other, and when the slave valve and the main valve are in a fully open state the first inclined surface and the second inclined surface abut each other.

  • Publication number: 20140169841
    Abstract: An image forming apparatus comprises: an imaging unit including imaging subunits that are arranged in a vertical direction, each of the imaging subunits forming a toner image of a different color; an intermediate transfer belt having a running surface that runs vertically along the imaging subunits, and on which the toner images are primary-transferred and superposed; a secondary transfer unit secondary-transferring the toner images on the intermediate transfer belt to the recording sheet; and an ejection unit having an outlet and a conveyance path extending vertically, the ejection unit conveying, to the outlet via the conveyance path, the recording sheet on which the toner images have been secondary-transferred, wherein when viewed from a front of the image forming apparatus, the imaging unit is arranged behind the intermediate transfer belt, and the conveyance path is arranged in front of the intermediate transfer belt.

  • Patent number: 8678386
    Abstract: Image forming apparatus having sheet transport device transporting sheet through nip between pressing and drive members by applying rotational force to drive member via power transmission mechanism that includes: first and second rotational shafts connected to drive member and drive source, respectively; first and second rotation transmitting members attached to first and second rotational shafts, respectively; holding member including first and second contact parts disposed on opposite sides of second rotation transmitting member; and rotational move member switching to power non-transmission and transmission states by moving holding member rotationally to first and second positions in conjunction with opening and closing operations of opening/closing member of apparatus housing. Power is not transmitted between rotational shafts in power non-transmission state and transmitted in power transmission state.
