Abstract: A cartridge is detachably mountable to a holder of an ink jet recording apparatus, so as to be freely reciprocatable to scan across a recording medium and record thereon by discharging ink. The cartridge is defined by a cartridge main body, and is provided with a recording head for discharging ink from plural nozzles formed in parallel on a lower face of the cartridge main body facing the recording medium. A front face of the cartridge main body is provided with an electrical connection portion having cartridge electrodes, which are electrically connectable with corresponding electrodes of the holder. A rear face opposite to the front face is provided with an ink connection portion connectable to corresponding supply ports which supply ink to the recording head from a main tank installed elsewhere on the ink jet recording apparatus. With the cartridge thus structured, the force exerted for connection to the supply port does not affect the precision with which the cartridge is mounted on the holder.

Abstract: A machine includes a pair of spaced supports, one of which may mount an operator such as a tool in a spindle and the other of which may mount an object such as a workpiece. The spaced platforms are joined by six powered and extensible legs joined to the respective platforms by universal joints. The length of the legs is individually manipulated to vary the position of the platforms and therefore the object and operator relative to each other in six axes. The powered legs may be hydraulic cylinders or recirculating ball screw driven. The distance between the spaced platforms may be measured by separate instrument arms which join the platforms. The instrument arms may use a digital position device to measure the extension and contraction of the instrument arms or may use a laser interferometer for that purpose. The changes in the instrument arm's lengths may be used to generate signals which are used to control the extension and contraction of the powered legs.
