    摘要： In one embodiment, the disclosure relates to an ink-jet head including an ink chamber, a pressure chamber in communication with the ink chamber, a nozzle for ejecting an ink in communication with the pressure chamber, a piezoelectric actuator for applying an ejection pressure to an ink in the pressure chamber, and an ink passage extending from a boundary of the ink chamber to a tip of the nozzle. The tip of the nozzle has an aperture diameter of from about 15 to about 25 μm, and the ink passage is configured such that when an ink having a viscosity of from about 2.5 to about 3 mPa·s is passed therethrough, a passage resistance value of the ink passage is from about 50 to about 100 kPa·s/mm3. Another embodiment of the disclosure relates to an ink-jet recording device containing such an ink-jet head.

Direct Yellow 132; not less than 0.5% by weight of glycol ether having a melting point of not more than −45°C.; and a water-soluble organic solvent in which a solubility of C.I. Direct Yellow 132 at 20° C. is not less than 5%. The ink satisfies 0.2≦B/A and 3≦C/A. B/A represents a weight ratio of the glycol ether to the C.I. Direct Yellow 132 contained in the ink, and C/A represents a weight ratio of the water-soluble organic solvent to the C.I. Direct Yellow 132 contained in the ink.

    摘要： A refrigerating apparatus includes a refrigerating cycle including a compressor, a condenser, a flow divider, a first heat exchanger, a second heat exchanger, a decompressing device, and an evaporator. The refrigerant cycle has sealed therein a mixed refrigerant obtained by mixing at least first to third refrigerants with different evaporation temperatures. The first heat exchanger and the second heat exchanger each includes a double pipe to form a first flow passage in an inner pipe of the double pipe, a second flow passage in an outer pipe of the double pipe, and an intermediate port in a piping connecting between the second flow passage of the first heat exchanger and the second flow passage of the second heat exchanger. A high-temperature and high-pressure refrigerant discharged from the compressor is cooled by the condenser to liquefy the first refrigerant having a high evaporation temperature into a liquid refrigerant.
