Abstract: A method of manufacturing a both-side metallized insulation film comprises steps of: depositing zinc or a blend of zinc and aluminum onto both sides of an insulation film; and winding this metallized film into a product roll. The method is characterized in spraying an oxidizing gas onto a deposited layer on an inner side of the insulation film to be wound, during the winding step. During a vacuum deposition step, an oil layer is formed on at least one side of the metallized film. In addition, an oxide layer is formed by exposing a deposited layer on at least one side to oxygen, or by spraying an oxygen-containing gas onto the deposited layer on at least one side during the winding of the metallized film into the product roll.

Abstract: An ink jet recording apparatus comprises a recording head including a discharge port for discharging ink, a first liquid chamber at the upstream side in the direction of ink flow toward the discharge port, and a second liquid chamber at the downstream side, an ink tank for containing ink to be supplied to the recording head, an ink supply tube for causing the ink tank to communicate with the recording head, a shut-off valve provided in the ink supply tube and opening or closing the ink supply tube, a cap for covering the discharge port; and a suction pump for forcedly discharging the ink in the recording head from the discharge port when the cap covers the discharge port.

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.
