An apparatus for preparing notches in material samples for fracture mechanics testing is disclosed. The apparatus includes a base and a sample holder for gripping a sample. A linear rail is inclined at an angle relative to the sample holder, and may be attached to an attachment column extending upward from the base. A carriage assembly attached to the linear rail includes: a carriage capable of sliding up and down along the linear rail and a blade holder attached to the carriage. The blade holder slides up and down the linear rail to initiate a notch in the sample.

A printer that partially cuts roll paper to leave an uncut portion prevents paper jams from reversing the roll paper. A printer 1 has a print unit 41 for printing images on roll paper R; a cutter unit 46 disposed downstream in the conveyance direction from the print unit for cutting the roll paper and leaving an uncut portion; a conveyance unit 42 for conveying the roll paper in the conveyance direction or a reverse direction that is the opposite of the conveyance direction; and a controller 40 that executes a reversing process conveying the roll paper in reverse by the conveyance unit 42 when the roll paper is separated from the paper roll at the uncut portion after the cutter unit 46 cuts the roll paper, and not executing the reversing process in specific circumstances in which the roll paper remains connected through the uncut portion.

Rotary cutting apparatus has a frame, a first rotary device and a second rotary device. Each of the first and second rotary devices has a shaft concentrically arranged about a rotational axis and a drum and are arranged in the frame in such a way that said first and second axes are substantially horizontal and substantially in the same vertical plane. A pair of bearing housings is arranged on either side of each of the drums. A first pair of bearing housings is movable relative to the frame in a transverse direction to the first rotational axis by means of a force means. Means is provided for passive vibration attenuation of at least the first shaft that includes a mass damper having a housing and a damping body movably arranged inside the housing, wherein the mass damper is associated with the first pair of bearing housings.

A cutting apparatus includes a blade relatively movable with respect to a media to cut the media along a cutting line. The blade is so constructed to pre-cut the media along the cutting line to leave non-cutting portions and to cut the non-cutting portions after pre-cutting the media.
摘要:
An aesthetically pleasing small form factor desktop computer is described. The small form factor desktop computer can be formed of a single piece seamless housing that in the described embodiment is machined from a single billet of aluminum. The single piece seamless housing includes an aesthetically pleasing foot support having at least a portion formed of RF transparent material that provides easy user access to selected internal components as well as offers electromagnetic (EM) shielding. This simplicity of design can accrue many advantages to the small form factor desktop computer besides those related to aesthetic look and feel. Fewer components and less time and effort can be required for assembly of the small form factor desktop computer and the absence of seams in the single piece housing can provide good protection against environmental contamination of internal components as well as EM shielding.
