Abstract: An image recording device may include corrugate mechanisms to prevent undesired bending and jamming of a recording sheet. In some examples, the image recording device may include a first corrugate mechanism, a second corrugate mechanism and a third corrugate mechanism. The first, second and third corrugate mechanisms may be configured to create a corrugated shape in a recording sheet. The second and third corrugate mechanisms, in one or more arrangements, may be located downstream of the first corrugate mechanism and an ink nozzle. The third corrugate mechanism may further be configured such that no upper contact portion thereof may be disposed at a same position, with respect to the width direction, as endmost upper contact portions of the first corrugate mechanism with respect to the width direction. In yet other examples, the third corrugate mechanism may be located downstream of a reverse sheet conveying path.

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.

Abstract: A positive electrode drive unit enables a positive electrode to be repeatedly rotated about the center of the positive electrode to vary a distance between the positive electrode and an atom emission unit. A control unit receives input data which is set to obtain a desired atom density distribution by displacement of the positive electrode, and the control unit outputs a drive control signal for displacing the positive electrode to the positive electrode drive unit. The positive electrode drive unit is stopped during running by the control unit, or a drive speed of the positive electrode drive unit is changed by the control unit. Therefore, a residence time of each attitude is changed in the positive electrode to vary the atom density per unit time.

Abstract: An electronic part mounting apparatus includes a chamber for cleaning a substrate and an electronic part by plasma, amounting mechanism for mounting the electronic part on the electronic part, and a conveying robot for conveying the substrate and the electronic part from the chamber to the mounting mechanism. After plasma cleaned, the substrate and the electronic part are swiftly conveyed to the mounting mechanism by the conveying robot. After the electronic part is mounted on the substrate by the mounting mechanism, the resultant combination of them is pulse heated. Therefore, the electronic part is appropriately mounted on the substrate in a state that those are exposed to the air. A part mounting mechanism is simplified.
