Title: Output correction apparatus of pressure sensor
Inventor: SATO SAICHI
IPC: G01L27/00
Filed: 1992-12-17
Abstract: PURPOSE:To avoid a sudden change and to perform a smooth changeover by a method wherein a sensor output value immediately before a changeover is used as an initial value so as to respond to the changeover timing of a selection means and the sensor output vale is corrected so as to be changed nearly rectilinearly for a definite time after the changeover. CONSTITUTION:Outputs from a plurality of pressure sensors 1.1 to 1.n whose measuring ranges are different from one another are changed over by a selector 2 and output. Their changeover is controlled by a controller 4, changed-over outputs are corrected and operated by a correction and operation part 3 so as to respond to a changeover timing and they are output to the outside as the outputs of the pressure sensors. For example, two kinds of pressure sensors as a high-pressure sensor and a low-pressure sensor are used. When the output of the low-pressure sensor reaches a changeover point, PHC which has been corrected and operated in the following manner is output to the output value of the changed-over high-pressure sensor during a period from its changed-over time t0 up to a prescribed time tn:PHC=PH-alpha{1-DELTAt/(tn-t0)} (where alpharepresents the difference in an output value between the low-pressure sensor immediately before a changeover and the high-pressure sensor immediately after a changeover and DELTAt represents a time shift from t0.) Thereby, a sensor output value rises nearly rectilinearly.

Title: Ink jet print head and ink jet printing device mounting it
Inventor: AZUMAYA YOSHIYUKI
IPC: B41J2/16
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To lessen adverse effect of a residual bubble in a head onto ink liquid ejection by producing a flow in the vicinity of a through hole in the head through hydrodynamic action of ink. SOLUTION: A high speed ink flow flowing from an ink channel toward the end 3 of an ink supply opening is deflected upon striking against the wall face of a protrusion 7 to provide a speed component in the direction of a common liquid chamber. Thee ink flow contains residual bubbles generated through cavitation of the high speed ink flow or micro bubbles entering from an ejection opening when ink is ejected and the micro bubbles are combined in an ink supply opening 8 to produce a bubble 11. Since the bubble in the vicinity of the supply opening 8 is subjected to an upward force from the high speed ink flow, bubbles carried away by the high speed ink flow adhere to a part remote from the supply opening 8 and grow thereat. Consequently, adverse effect onto ink supply is suppressed even if a large number of large bubbles are present and insufficient ink supply is prevented.
