Title: Ink jet head
Inventor: KITAHARA TSUYOSHI
IPC: B41J2/045
Filed: 1988-07-21
Abstract: PURPOSE:To obtain an ink jet head favorable in production yield, drivable at a low voltage, and stable in ink drip discharge characteristics by applying a selective electric signal to a heating means forming a pressure generation means. CONSTITUTION:With the application of electric signals to electric signal lines 25, 24, an electric current flows in a direction shown by an arrow 60, and a heat generation layer 26 heats to increase in temperature rapidly. The thermal energy generated in the heat generation layer 26 is conducted to an adjacent recording ink 31 and a vibration plate 23. Here, in consideration of an unconstant thermal conduction especially in the direction of the thickness of the vibration plate 23, in a pressure generation member 40, which has been initially in a uniform temperature state, a temperature gradient occurs inside by the heat generation of the heat generation layer 26 and a thermal stress attributed to the thermal expansibilities of the components is generated. A bending moment is generated in the pressure generation member 40 by this phenomenon. The pressure generation member 40 is deformed and displaced toward a nozzle plate 21 because it is fixed at one end, thereby making the recording ink 31 in the vicinity of a nozzle opening 20 fly out of the nozzle opening 20 as an ink drip.

Filed: 1986-08-06
Abstract: PURPOSE:To measure the flow rate of a fluid in a fine flow rate area, by arranging a pair of control ports provided symmetrical with the center line close to an inflow while being connected to a main passage through respective control nozzles. CONSTITUTION:When a fluid flowing out of a light transmitting and inflow port 4-1 is jetted into a main passage 4-3 from a main jet nozzle 4-4, it flows along either of wall surfaces of the main passage 4-3 by Coanda effect to cause a pressure difference between both sides of the main passage 4-3, which generates, for example, a flow being transmitted through one wall surface control nozzle 5-3 for the main passage 4-3, a control port 4-5 and a control nozzle 4-6. This changes the direction of the main passage to a wall surface 4-3b on the opposite side to a wall surface 4-3a while the flow is turned to a vortex. A fluid containing a pressure vibration flows in a vortex and a free end of a diaphragm 13 vibrates receiving the pressure vibration. The pressure vibration is detected with a piezo-electric film 14 thereby enabling measurement of a flow rate in a fine flow rate area.
