Filed: 1982-09-14
Abstract: PURPOSE:To improve thermal efficiency and prevent freezing trouble as well as rusting of circulating pipelines or the like by a method wherein a heating medium, having high boiling point and low solidifying point, is sealed into a circulating pipeline between a heat exchanging part and a heat source. CONSTITUTION:Ethylene glycol is sealed into the circulating pipeline 1 as the heating medium. It has physical properties of molar weight 62.07, boiling point 197.6 deg.C, solidifying point -13.0 deg.C, specific gravity 1.1155 and specific heat 0.56 and is slightly viscous non-volatile liquid having no color, no smell and sweet taste. The heating medium in the circulating pipeline 1 is heated by an electric heater 3 at the outside of the heat exchanger while the heat of the heating medium is dissipated at the heat exchanging part of the pipeline 1, which is meandering in the heat exchanger and provided with fins 4 on the outer periphery thereof. A fan 5 sends air vertically to the surface including the heat exchanger and the air is blown out as hot-air after passing through the fins. The capacity of the electric heater 3 is small and heat is accumulated in the heating medium even if it is heated for a long period of time since the specific heat of the heating medium is small and the boiling point thereof is high while the hot-air is blown off immediately after beginning of the ventilation of the fan 5.

Abstract: PURPOSE:To minimize variation in the discharge condition of ink from a nozzle by positioning all liquid paths of a plurality of ink discharge nozzles arranged vertically in a row with respect to a recording head above the ink liquid surface of an ink reservoir section to impart a proper negative pressure to ink in the liquid path. CONSTITUTION:The liquid surface of an ink A in an ink reservoir section 4 is communicated with the outside air while nozzles 16 done therewith. Consequently, a negative pressure of L works on the ink in the highest one of the paths 15 in terms of a head difference. With the consumption of the ink, the ink liquid surface of the ink reservoir section 4 further drops by H, which applies a negative pressure of (L+H) in terms of head difference. Likewise, a negative pressure ranging from M to (M+H) works on the ink in the lowest one of the liquid paths 15. In this manner, proper impartment of the negative pressure makes the meniscus 26 of an ink liquid in the nozzle 16 concave and the retreatment thereof is also held within an appropriate range. Even in the discharging of from the nozzle 16, a specified amount of liquid drops are discharged to ensure a better interruption of the ink discharge thereby maximizing the driving efficiency of an ink discharge driving element 17.
