Abstract: A head unit is inverted so that an outflow port is in the lowest position. Because the top wall of the buffer tank slopes downwards towards the outflow port, all remaining cleaning fluid that was introduced during manufacture is removed. Also, a notch is provided in the bottom end of an ink introduction port. The notch faces towards the outflow port so that bubbles in the ink exit from the notch and are guided towards the outflow port. The head unit is shipped while the buffer tank is filled with preservation fluid that has high wettability and any openings to the outside air are closed off with covers. When the head unit is used, the preservation fluid is sucked by a purging device and then ink, which has a high affinity for the preservation fluid, is smoothly introduced. Also, the inner surface of the filters are treated to increase the wettability by ink after the filters are fixed to the bottom lid. Afterwards the bottom lid is fixed to the top lid to form the buffer tank.

Abstract: In order to make a thermoelectric device usable in a high temperature environment of 300° C. or above, the necessity for solder is eliminated by bonding each electrode of a second substrate to one end of each thermoelectric element by using gold. Further, a conductive member, capable of accommodating expansion and contraction of the thermoelectric elements, is provided between each electrode of a first substrate, on which bonding by gold is not performed, and the other end of each thermoelectric element. Additionally, a lid is placed outside to the second substrate, and the lid and the first substrate are coupled so that pressure can be applied between the first and second substrates. Thus, the second substrate, the electrodes and the thermoelectric elements are held. This prevents the thermoelectric elements from being damaged due to thermal deformation as in the case where electrodes are bonded to thermoelectric elements by solder.

Abstract: In a thermoelectric device, metal fiber nets as conductive members having elasticity are placed between first electrodes and thermoelectric elements, in order to increase productivity and make it possible to reduce variations in performance without impairing the reliability of a slidable structure even if each component is heated to be thermally deformed. This placement prevents the temperature of the metal fiber nets from becoming high in the operation of the thermoelectric device and prevents the elasticity of the metal fiber nets from being lost. Further, this constitution eliminates the necessity for bonding the first electrodes to the thermoelectric elements using solder. Moreover, the elasticity of the metal fiber nets makes it possible to accommodate variations in height among the respective thermoelectric elements when the thermoelectric device is assembled.

Abstract: An ink-jet head comprises a joint member having an ink outlet port out of which ink supplied from an ink supply source flows, and a passage unit having an ink receiving port that receives the ink flowing out of the ink outlet port of the joint member. A filter is disposed within a first ink passage inside the passage unit. The first ink passage extends in the same direction as an ink flow direction from the ink outlet port to the ink receiving port. In the first ink passage of the passage unit, a first space is formed between the ink receiving port and the filter, and a second space is formed contiguous to the first space with the filter interposed between the first and second spaces within the first ink passage. The cross-sectional shape and size of each space in a direction perpendicular to an ink flow direction are constant along the ink flow direction.
