Abstract: In some examples, a fluid ejection die includes a plurality of nozzles arranged in a plurality of nozzle columns, the plurality of nozzle columns distributed across a width of the fluid ejection die in a staggered manner, wherein nozzles of each respective nozzle column of the plurality of nozzle columns are spaced apart along a length of the fluid ejection die, wherein the plurality of nozzle columns includes a first pair of neighboring nozzle columns that are spaced by a first distance across the width. The plurality of nozzle columns includes a second pair of neighboring nozzle columns that are spaced by a second distance across the width, the second distance being larger than the first distance.

Abstract: A bicycle pedal assembly having a pedal body rotatably coupled to a pedal shaft. A bore receiving the pedal shaft passes through the pedal body. A semi-cylindrical shoulder extends outwardly from an exterior surface of the shaft. A bushing is positioned within the bore to rotatably support the pedal shaft. An inner surface of the shoulder rotatably engages the external end of the bushing, so that the second end of the shaft is movably connected to the pedal body without assistance of any fasteners.
