Abstract: A pattern formation device includes a conveyance table, a pair of guide rails, a carriage, a plurality of droplet discharge heads, an inspection camera, a camera base, a linear motor, a motor housing case, a moving cable, and a cable housing case. The motor housing case is disposed along the guide rails to accommodate the linear motor and has a guide opening configured and arranged to guide the camera base. The cable housing case is disposed along the motor housing case to accommodate the moving cable and has a window section through which a distal end of the moving cable follows a reciprocal operation of the inspection camera. The cable housing case or one of the guide rails has an exhaust vent to discharge air around the carriage by suction through the window section of the cable housing case or the guide opening of the motor housing case.

Abstract: A capping fixture is adapted to be coupled to a droplet discharge device including a droplet discharge head aligned on a unit plate of a carriage. The capping fixture includes a base panel, a head cap portion and an elastic member. The head cap portion is disposed on the base panel at a position corresponding to the droplet discharge head to hermetically seal the droplet discharge head when the capping fixture is coupled to the carriage of the droplet discharge device. The elastic member elastically couples the head cap portion with the base panel so that the head cap portion is movable within a prescribed distance in a direction substantially perpendicular to the base panel.

Abstract: To provide an optical assembly capable of enhancing black level display while preventing deterioration of a WV film, and a projector assembled therewith, optical compensation elements are disposed before and after liquid crystal light valves, so that an unintended phase difference generated on the incident and emission sides of the liquid crystal light valves for individual colors is eliminated by adjusting the rotational positions of the optical compensation elements, thus enabling an enhancement in the contrast of a color image displayed on a transmission screen member.
