    摘要: In an inkjet recording apparatus in which a single ink supply path for hermetically sealing an ink tank and a recording head from the atmosphere is formed by connecting the ink tank to first and second hollow needles. When the ink tank is detached, the flow path is sealed in association with mounting and dismounting of the ink tank, thereby leakage of ink to the outside of the apparatus is prevented.

    摘要: In a method of multiple electrode gas shielded arc welding wherein a plurality of electrodes are arranged along the welding seam line of a piece of metal to be welded and continuous gas shielded arc welding of the piece is accomplished simultaneously by the electrodes, the chemical composition of the electrode wire of the electrode or electrode group for depositing a preceeding layer or layers is selected to differ from that of the electrode wire of another electrode or electrode group for depositing a subsequent layer or layers, whereby the chemical composition of the weld metal made by the preceeding welding operation is brought near to that of the weld metal made by the following welding operation and thus the uniform properties are ensured for welding metals at the respective positions in the weld zone.

    摘要: 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. The shut-off valve is opened when the first and second liquid chambers are reduced to respectively desired pressures by the suction pump in a state where the cap covers the discharge port and the shut-off valve is closed, whereby the ink in the ink tank is supplied through the ink supply tube to the first and second liquid chambers.
