Abstract: A recording apparatus includes a conveyance unit that conveys a recording medium in a first direction toward a recording head for ejecting a liquid, a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction, a rotatable lever that holds a tank cap for closing the injection port, and a cover that rotates about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction. The cover includes a sliding portion that is provided on a surface facing the lever and comes into contact with the lever while the cover is rotating toward the closed position.

Abstract: A recording apparatus includes a tank including a chamber configured to store liquid to be supplied to a recording head that ejects the liquid and a filling port from which the liquid is injected into the chamber, and an injection auxiliary member configured to assist injecting of the liquid into the chamber from the filling port, the injection auxiliary member including a first and a second flow channels each defined by a first or a second upper end portion that opens toward outside of the tank and a first or a second lower end portion that opens toward inside of the tank, wherein the second flow channel has an expansion portion arranged in a middle portion between the second upper end portion and the second lower end portion and configured to form a step to expand a cross-sectional area.

Abstract: An elevator is capable of transmitting signals between an elevator control unit and a car control unit without using tail cords. Resin-coated ropes for suspending an elevator car and a counterweight comprise conductive metal wires. Transmitter-receivers use the conductive metal wires of the ropes for contactless signal transmission. The conductive metal wires of the two ropes are connected in rope-anchoring parts to form an electrical closed loop for signal transmission.

Abstract: A method of forming a non-circular pipe having a different sectional shape in the longitudinal direction thereof by bending a raw pipe while applying pressure to the inside of the raw pipe, wherein the circumference of a section of the raw pipe is substantially equalized to the circumference of a section, corresponding to the section of the raw pipe, of the non-circular pipe after formed.

Abstract: A method of relieving residual stress in a metal pipe comprises the steps of applying, by using a pressure medium, a low pressure to an interior of the metal pipe placed in dies, and applying, while preventing the buckling, an axial compression load to the pipe so as to effect a uniform plastic deformation of the entire metal pipe while maintaining the desired shape of the pipe, thereby relieving the residual stress in the metal pipe.
