Title: Surface acoustic wave device
Inventor: FUJITA YUUJI
IPC: H03H3/08
Filed: 1984-06-13
Abstract: PURPOSE:To obtain a characteristic suitable for a given specification by using different length for double electrode fingers of the same polarity of a weighted electrode at each pair in a range smaller than a gap between each finger pair and a dummy electrode finger and selecting said gap to a value within a specific range so as to suppress a spurious surface acoustic wave. CONSTITUTION:The group delay flatness is made almost flat where an aperture length 7 is lambda, a weighted pair number is 8.5 pairs and the center 7 of each crossing part is on the center line of the propagating axis in the effect to diffraction of a surface acoustic wave on the group delay characteristic, but the group delay characteristic is disturbed largely in taking the unnecessary crossing with the dummy electrode finger into cinsideration. On the other hand, when the gap LG with the dummy electrode finger is 0.2lambda and the length of adjacent electrode fingers is made different by 0.4LG, a value DELTAl is <=0.71lambda, no unnecessary crossing is caused and the deterioration of the group delay characteristic is effected by the diffraction only. Further, the surface acoustic wave is stimulated independently of the length of the LG in the relation between said gap LG and the group delay flatness and tee deterioration in the group delay charactristic is incurred. Thus, it is necessary to suppress the group delay flatness as <=20 ns p-p with the gap LG between 0.1lambda-0.26lambda.

IPC: B41J2/06
Filed: 1986-05-27
Abstract: PURPOSE:To prevent a thermal degradation of ink and to enable a high speed high density recording, by applying a thermal energy according to an image signal of ink filled in a slit space section, and flying a portion of heated ink to a recording sheet side based upon a specified electrostatic field. CONSTITUTION:In a head body 1, glass substrates 2, 3 are arranged through a spacer member 4 to form a slit space section 5 while a control electrode 6 and an opposed electrode 8 are arranged on the inner face side of the glass substrates 2, 3 and the non-exposed portion of the control electrode 6 is covered with an insulative protection layer 7. Ink 10 dissolved with an oil soluble dye having a resistivity of at most 10<7>OMEGAcm is fed through a pressurizing means into the slit space section 5. When a control voltage corresponding to an image signal is applied onto the control electrode 6, an ink layer 10 positioned between the electrode 6 and the opposed electrode 8 is supplied with power and heated, thereby the viscosity and the surface tension decrease while the conductivity increases. Since an electrostatic field is formed on the surface of the ink 10 and the layer of an electrostatic induction electrode 11, the ink portion 10 is attracted electrostatically to the side of a recording sheet 12 so as to form ink dots thereon.
