  • Feed apparatus and image recording apparatus
    Patent number: 9145275
    Abstract: There is provided a feed apparatus including a support unit; a feed roller; a swingable arm to support the feed roller; a guide unit; a movable member movable to a retracted position and a protruding position at which the movable member can abut against the sheet supported by the support unit; a driving source; driving transmission units; and a contact-separating mechanism to move the feed roller to a separated position and an abutment position at which the feed roller abuts against the sheet supported by the support unit. In a state in which the movable member is the protruding position and the feed roller is the separated position, a time required to start feeding of the sheet by the feed roller moved from the separated position to the abutment position is longer than a time required to shift the movable member from the protruding position to the retracted position.

  • Inkjet recording apparatus
    Patent number: 9139014
    Abstract: Conveyance of a sheet in an inkjet recording apparatus may be stopped under various conditions. In one example, a control device of the inkjet recording apparatus may stop conveyance on the sheet depending on the image to be formed in one or more portions of the sheet. Alternatively or additionally, conveyance may be stopped based on an amount of ink ejected or to be ejected onto a sheet, or portion thereof. The conveyance stoppage control may be used in conjunction with a corrugate mechanism in some arrangements.

  • METHOD FOR MANUFACTURING ELECTRODE SHEETS AND APPARATUS THEREFOR
    Publication number: 20140325833
    Abstract: According to the method for manufacturing electrode sheets, in a first cutting step, an original sheet, including a belt-shaped metal foil and an electrode material coated thereon in a lengthwise direction to form a plurality of coated portions spaced at a predetermined gap, is cut at a location between the coated portions. In a pressing step, the original sheet strips having been cut in the first cutting step are pressed. In this case, the original sheet strips that are pressed by the rolling device are independent from each other. Therefore, the effect produced in rolling of the coated portions remains within each of the original sheet strips. In addition, distortions occurring in the original sheet strips can be prevented from affecting each other and the occurrence of wrinkles can be inhibited.

  • Method of forming FeCrO(O
    Patent number: 8821973
    Abstract: Both ends of a circulation pipe of a film formation apparatus are connected to a piping of a BWR plant. A chemical including chromium ions and formic acid is injected into a film formation solution flowing in the circulation pipe heated to a temperature within a range from 60° C. to 100° C. Furthermore, a chemical including iron (II) ions and formic acid, hydrogen peroxide, and hydrazine are injected into the circulation pipe. Due to the injection of these chemicals, a film formation solution of pH 7.0 including iron (II) ions, chromium ions, formic acid, hydrogen peroxide, and hydrazine is generated in the circulation pipe. This film formation solution includes hydrazine of, for example, 1000 ppm. The film formation solution is supplied to the piping, thus, a Fe3—xCrxO4 film (here, 0<X?0.1) is formed on the inner surface of the piping. The above method of forming the ferrite film on a structural member (for example, the piping) can be shortened time required to form the ferrite film.
