Title: Ink jet recording head
Inventor: MORIYAMA JIRO
IPC: B41J2/015
Filed: 1985-12-17
Abstract: PURPOSE:To realize a small-size against multi-nozzle structure, a low production cost, and an enhanced electro-mechanical conversion efficiency, by a method wherein in a cross section of a piezoelectric element, the length in the predetermined direction is made different from that at right angles thereto and electrodes are provided only on the outer surfaces. CONSTITUTION:A positive pulse voltage generated in a pulse generator 2 is applied through a connection wire 6 to electrodes 12 on the upper and lower surfaces of a piezoelectric element 11. Being applied with the voltage through the electrodes 12, the piezoelectric element 11 is maintained in its axial length (1) but compressed only in its vertical length, thus elongating the horizontal length. Therefore, an electro-mechanical conversion efficiency is enhanced, and furthermore, the piezoelectric element 11 has not cylindrical outer shape but a horizontal length shorter than a vertical length. As a result, in a multi- nozzle consisting of a plurality of piezoelectric elements, a pitch P2 in the each piezoelectric element 11 is made remarkably shorter than a pitch P1 in a conventional circular piezoelectric element. In this manner, a nozzle portion 7 has a shorter total width in a parallel direction, thus forming a small-size nozzle.

IPC: G01C19/72
Filed: 1987-11-07
Abstract: PURPOSE:To obtain accurate angular speed information without noise influence by a method wherein a reference signal for synchronously detecting a basic wave component is obtained by dividing into two a secondary higher harmonic wave. CONSTITUTION:A light emitted from a light emitting element 10 is transmitted through a sensor coil 20 into a light receiving element 26, where it is square-law- detected and amplified 22. Of said amplified signal, only basic wave component P (DELTAtheta, t) of an angular frequency OMEGA is permitted through a filter 36 and synchronously detected 34. Of an amplified signal 32, a secondary higher harmonic wave is selected by a filter 37, shaped into a rectangular wave in a comparator 100 and 1/2-divided 42. In other words, a counter 102 converts oscillation 2OMEGA into an oscillation OMEGA. Then an angular frequency of a phase modulation drive circuit 22 makes oscillation OMEGA into a rectangular wave at a comparator 101 and inputs it into a clear terminal of a comparator 102, which is cleared at every frequency of phase modulation. Then a phase correction circuit 40 gives a phase difference PSI' to the output of a divider 42, permitting a reference wave P (DELTAtheta, t) and reference signal w(t) free of phase difference to be obtained.

Filed: 1988-11-09
Abstract: PURPOSE:To lessen the heat generation of resistors and to reduce a loss in a detecting circuit for the output voltage by dividing a D.C. bus voltage of the main circuit by the resistors. CONSTITUTION:The voltage of a point Q is made to be 1/2Vdc by the resistors R 11 and R 12 having the same resistance values. When a switching element Ta<+> is in the ON state or a diode with inverse direction of the Ta<+> is in the ON state, the voltage of a point U is made to be high. At this time, the current flowing from the point U to a D.C. bus dividing point Q is interrupted by a reverse-current interrupting diode and a photocoupler is made OFF. Further, when the switching element Ta<-> is in the ON state or the diode with inverse direction of the Ta<-> is in the ON state, the point U is made low, and this time the current is made to flow from the D.C. bus dividing point Q to the point U passing through the photocoupler, diode and resistor, and the photocoupler is made to be ON. Then, the power consumption of the resistors is reduced in the voltage detecting circuits 1-3 in the manner of dividing the D.C. bus voltage of the main circuit by the resistors.
