Title: Ink jet head and ink jet recording apparatus
Inventor: TONO NAN
IPC: B41J2/055
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a great volume change by deforming a second wall part on the basis of the deformation of a first wall part having a part formed of a shape memory material. SOLUTION: A shape memory substrate 20 is formed of a plate having a thickness of approximately 1-several μm of an optional shape alloy, e.g. TiNi alloy. The substrate 20 is bonded to another face of a channel plate 8 at a martensite phase (ordinary temperature) not higher than a transformation point. At this time, the substrate is extended to apply an initial distortion in a direction orthogonal to a longitudinal direction of ink channels 10. A predetermined voltage (pulse voltage) is impressed to an electrode corresponding to the selected ink channel 10, whereby a corresponding deformation wall 32 heats. When the deformation wall 32 reaches the transformation point, the substrate is transformed from the martensite phase to a mother phase (high temperature) and is deformed to a state before the initial distortion is applied.  As a result of this, walls 12 at the side of ink channels are bent inside and the ink of the corresponding ink channel 10 is pressured and discharged from a nozzle.

Filed: 1983-05-13
Abstract: PURPOSE:To perform temperature control in an accurate manner with no current limiting resistance, by increasing series connection numbers in connection and arrangement of glow plugs according to a shift in conditiolns of preheating, cranking and afterglow of an internal-combustion engine. CONSTITUTION:When a key switch is turned to ON, a relay 22 is energized with current, and glow plugs 101-104 are all connected in parallel whereby a large current flows there. When this large current is selected for starter motor operation, a relay 26 is energized, causing these glow plugs 101-104 to become series- parallel connection two by two, and thereby a relatively small current flows there. After complete combustion of an engine, a relay 27 is energized by an afterglow control circuit 19, then these glow plugs 101-104 are all connected in series, and overheating is prevented from occurring. This time continues for the duration of delay time and afterward, afterglow comes to a stop. With this constitution, temperature control can be done in an accurate manner with no current limiting resistance.
