摘要:
A printer includes a cleaning mechanism that reliably performs an operation of cleaning a liquid ejecting head with a small amount of driving energy. The cleaning mechanism includes a cap manufactured by coinjection molding of a core part and an elastic part. The cap includes a bottom surface, an outer wall, and a partition wall dividing a cap inner space surrounded by the outer wall into two. A ratio of the elastic part in the partition wall is higher than that in the outer wall. With this structure, the partition wall is more elastically deformable than the outer wall. When the cap comes into contact with a nozzle surface of a recording head and covers nozzle rows, the outer wall comes into contact with the nozzle surface with a larger stress compared with the partition wall, and seals chambers where the nozzle rows on the nozzle surface are exposed.

Purpose: A process for preparing a liquid organic isocyanate having a carbodiimide group and/or an uretonimine group, excellent in storage stability. Solution: In a process for preparing a modified polyisocyanate by carbodiimidizing an organic polyisocyanate in the presence of a phospholine-based catalyst, silicon dioxide particles having a specific surface area of at least 400 m2/g and an oil absorption of at least 180 ml/100 g are used to adsorb and inactivate the catalyst to thereby terminate the carbodiimidization reaction.

摘要:
In an ink jet recording apparatus, a recording head is mounted on a carriage which reciprocately moves in a widthwise direction of recording paper. A subtank is mounted on the carriage for supplying ink. A main tank stores ink which is replenished to the subtank. An ink amount detector detects an amount of ink stored in the subtank. A replenishment controller controls replenishment of ink stored in the main tank to the subtank, in accordance with the ink amount detected by the ink amount detector.
