  • Patent number: 9897219
    Abstract: The pressure reduction valve includes: a cylindrical portion, a piston and a spring. The cylindrical portion includes an inlet communicating with the primary side flow path and an outlet communicating with the secondary side flow path. The piston fitted into the cylindrical portion is slidable along an axis direction of the cylindrical portion within the cylindrical portion, and defines, within the cylindrical portion, a space communicating with the inlet and the outlet. The spring applies, to the piston, a force acting toward the space. The outlet is displaced in one direction from the center of the piston when seen in the axis direction. The force applied to the piston by the spring is distributed so as to deviate from the center of the piston to the side of the outlet.

  • Patent number: 9885979
    Abstract: A toner filling apparatus includes a filling tank, a toner filling path forming member, a toner fluidizing unit, a filling path opening/closing unit and a container room sucking unit. The toner filling path forming member is in communication with the filling tank and forms a toner filling path connected to the toner container. The container room sucking unit sucks air from the toner container through a filter member which is impermeable to the toner but permeable to air. When the toner fluidizing unit fluidizes the toner in the filling tank and the filling path opening/closing unit opens the toner filling path so as to load the toner to the toner container, the container room sucking unit reduces a pressure in the toner container to a negative pressure so as to draw in the toner into the toner container.

  • Cap
    Patent number: 9884551
    Abstract: A cap includes a main body attached to an end part of a charging port for fuel gas. The main body includes an elastic deformable portion for locking the main body to the end part when the main body is attached to the end part. The cap further includes a cover covering at least part of the elastic deformable portion and surrounding the main body. The elastic deformable portion at least partially elastically deforms when the main body is attached to the end part and when the main body is detached from the end part. The cover is a separate member from the main body. When the elastic deformable portion elastically deforms, the cover applies force to the elastic deformable portion in a direction opposite from the deforming direction.
