Title: Ink jet head
Inventor: IKEDA KUNIO
IPC: B41J2/16
Filed: 1985-03-26
Abstract: PURPOSE:To reduce the area of an ink-pressurizing liquid chamber and contrive integration of a head, a lower cost and enhancement of automatic assembling property, by a construction wherein a vibrating plate in a vibrating unit and a conductor circuit for impressing a power source voltage to drive the unit are integrally formed from the same member. CONSTITUTION:A diaphragm sheet 2 is adhered to a head base 1 to form the ink-pressurizing liquid chamber 3. A conductor 6 and the vibrating plate 7 formed as one body are adhered to a support 4 through a spacer 5. An electrostrictive vibrator PZT 8 is adhered to the plate 7 by an epoxy adhesive. A vibration-transmitting rod 9 for transmitting vibration of the plate 4 to the diaphragm 2 is adhered to the diaphragm by an adhesive. The PZT 8 and the conductor 6 are connected to each other by a lead wire 10. Accordingly, since the large displacement of the vibrator supported at one end thereof is transmitted to the diaphragm constituting a wall of the liquid chamber 3, a large capacity change can be generated even where the area of the liquid chamber is small.

IPC: H05B33/26
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To enhance adhesion between a negative electrode and an organic layer and improve luminous efficiency by interposing an Ag adhesion layer between the negative electrode and the organic layer and forming the Ag adhesion layer in such a thickness that it does not affect electron injection efficiency. SOLUTION: An ITO(indium tin oxide) film is formed as a positive electrode 13 on a substrate 11 by means of deposition or spattering and an organic layer 15 is formed on the positive electrode 13. An Ag adhesion layer 19 is formed on the organic layer 15 and then a negative electrode 17 is formed on the Ag adhesion layer 19. The thickness of the Ag adhesion layer is set to 4 nm even at a maximum so that it does not deteriorate the electron injection efficiency of the negative electrode. When the organic layer 15 is composed of an organic positive-hole transporting layer 21 and an organic electron transporting luminescent layer 23, the Ag adhesion layer 19 is consequently present between the organic electron transporting luminescent layer 23 and the negative electrode 17. A current blocking layer, a buffer layer or a charge injection layer may be formed in the organic layer 15.  The substrate 11 is formed from a transparent substrate such as a glass substrate or as transparent film.

Filed: 1980-05-08
Abstract: PURPOSE:To shorten a time of adjustment, by simultaneously writing in the adjusting points existing at the positions symmetrical to the horizontal and vertical axes passing the center of a screen to a 1-frame memory. CONSTITUTION:The cursor key and the write-in key of a control panel 1 are operated to simultaneously write-in the adjusting points A1, A2, A3 and A4 existing at the positions symmetrical to the horizontal and vertical axes passing the center of a screen to a 1-frame memory 3. Then the compensating data of the adjusting point designated by the cursor key is written in to the memory 3 by an address counter 16. At the same time, the data for the points of control existing at the positions symmetrical to the horizontal and vertical axes is written in the memory 3. This compensating data is read out and converted into an analog quantity through a D/A converter 9 to be smoothed by a low-pass filter 10 to compensate a convergence. As a result, the convergence can be compensated over the entire screen only by writing in the compensating data of e.g. the adjusting point A1 within the first quadrant to the memory 3.

Abstract: PURPOSE:To generate a signal based on deterioration in sound quality, i.e. the degree of dirtiness of a CD by obtaining a signal which indicates an error correction state in the form of a pulse train and weighting the signal by varying the width of respective pulses which constitute the pulse train. CONSTITUTION:The output pulse train corresponding to the correction state of an error correcting circuit 1 appears at the output terminal of a flip-flop circuit 12 according to the output states of the 1st- the 6th latch circuits 3-8. The output signal of the flip-flop circuit 12 is smoothed by a low-pass filter 13 and then a DC voltage based on the correction state of the error correcting circuit 1 is obtained. For the purpose, the DC voltage is impressed to a meter to display the dirty state of a CD linearly. Further, the DC voltage is impressed to a circuit having a specific threshold level to drive a light emitting diode, which is made to illuminate only when the state of the CD is inferior. In this case, the pulse train is weighted so that respective pulses constituting the pulse train are different in pulse width, so an error correction state which is important and an error correction state which is not important can be discriminated.
