Abstract: PURPOSE:To obtain an ink jet head small in resistance to ink flow and excellent in printing quality at low costs by a method wherein a nozzle forming member is of the laminated structure of two members: one is a plate-like member having a circular hole and the other is a high-molecular resin film member having a hole with a smaller diameter than the aforesaid circular hole. CONSTITUTION:A nozzle plate 16 consists of the assembly of a nozzle plate 16A having a hole with a large diameter and a nozzle plate 16B having a hole with a smaller diameter than the aforesaid hole. An ink is fed from the upper surface of the nozzle plate 16A and discharged from the lower surface of the nozzle plate 16B. These nozzle plates are of a laminated structure formed by joining together a high-molecular resin film having formed therein a hole with a highly accurate diameter and a rigid member having formed therein a hole larger than the hole on the ink discharge side, whereby the combined features of the rigidity and the hole diameter accuracy can be provided. By making the hole diameter on the ink supply side larger than that on the ink discharge side, the nozzle plate is realized without increasing resistance to the ink flow and, since the hole with a highly accurate diameter can be formed on the ink discharge side, the ink delivery characteristics can be improved.

In this case, valves 41 and 43 are opened beforehand. When valves 26 and 31 are opened at the time pressure gauges 40 and 42 indicate the same indication, dead water is discharged in the discharge passage 34 through valves 26 and 31 and discharge pipe 33. When cooling water in the water intake passage 21 is turned into pure water, the operation of the pump 22 is stopped. By so doing, it is possible to discharge dead water without providing large and expensive facilities.

Abstract: PURPOSE:To reduce the power consumption of the electronic equipments by providing a power cut-off circuit to the intermittent power control circuit of each electronic equipment to cut off the power supply of each equipment based on a cut-off control signal. CONSTITUTION:A power cut-off circuit 10 is provided to the intermittent power control circuit of each of electronic equipments which are connected to each other in a loop shape. When a command is produced to cut off the supply of power to a specific one of electronic equipments, this command is inputted to the circuit 10 and the output of the circuit 10 is set at an L level. Thus no current flows to a base I of a transistor TR5. As a result, a relay RL5 is turned off and the supply of power is cut off to the output side (power supply part of electronic equipment) of the power supply of a connector 7. Thus it is possible to cut the power supply to the unnecessary electronic equipments only. Then the power consumption can be reduced to the electronic equipments.
