Filed: 1994-10-12
Abstract: PURPOSE: To improve the printability, levelability and sharpness of hydrophobic fabric by using a specific urethane resin as printing pretreatment agent to raise the infiltration ability of the fabric. CONSTITUTION: This printing pretreatment agent contains a urethane resin with the water absorption at 115wt.% of its own weight having in the molecule 5-80wt.% of polyoxyethylene groups which is prepared by one of the following processes: by reaction of an organic isocyanate compound A with an ethylene oxide-added product B formed by adding ethylene oxide to at least one kind selected from low-molecular polyols, polyhydric phenolic compounds and amines; by reaction between the compound A, the ethylene oxide-added product B and an active hydrogen compound C other than the product B; by reaction of the compound A with a hydroxyl-terminated polyester D prepared by reaction of the product B with a low-molecular dicarboxylic acid; and by reaction between the compound A, the compound C and the polyester D.  The second other objective printed product is obtained by pretreatment of hydrophobic fabric with the above pretreatment agent followed by conducting a printing treatment.

Title: Ink jet printing head
Inventor: KATAOKA MASAKI
IPC: B41J2/05
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a more inexpensive small-sized high capacity and high quality ink jet printing head by improving assembling properties in a head using a resinous passage substrate. SOLUTION: A plurality of heating elements 11 and the electrodes 12, 13 connected to the heating elements are formed on a heater chip 1 and the heating element protecting layer 14 extending from the heating elements 11 in an ink emitting direction are formed so as to cover the heating elements 11. Radiation is accelerated in this extended part. Further, a resin layer 15 is formed to the part joined to the passage groove wall 22 of a passage forming member 2 behind the ink emitting direction from the heating elements 11. Since the bonding with the resin layer is performed upon the pressure contact with a resin passage member 2, small pressing force may be used and bonding can be performed easily. Since there is no resin layer 15 in an ink emitting direction from the heating elements, the pressure due to generated air bubbles goes toward a jet orifice 22 to efficiently emit ink.

Title: Digital audio device
Inventor: INAGAKI YUSHI
IPC: G11B20/10
Filed: 1988-09-30
Abstract: PURPOSE:To remove the distortion of high-frequency bands produced when sounds discontinue and to prevent occurrence of a state where sounds are disagreeable to hear by removing the high-frequency bands from sampling data at the time of fast forward reproduction. CONSTITUTION:When fast forward reproduction is commanded from a user, the 1st switch 7 selects the 3rd output-side bit of the 1st shift register 2 as a selected output under the switching control of a control circuit 14 synchronous to a left/right from selecting clock LRCK. The 2nd and 3rd switches 8 and 9 respectively select the 2nd output-side bit of the 3rd shift register 4 and the 3rd output-side bit of the 5th shift register 6. The 4th switch 12 selects the added output of the 2nd serial adder 11. Thus readout digital audio data are sampled at prescribed time intervals and high-frequency bands are removed from the sampling data, and then, the sampling data are outputted after the data are connected and reproduced. Therefore, the distortion of the high-frequency bands produced when sounds discontinue can be removed and occurrence of a state where sounds are disagreeable to hear is prevented.

Title: Method and apparatus for evaluating toner charge characteristic
Inventor: TSUBOTA NORIAKI
IPC: G01N27/60
Filed: 1984-11-27
Abstract: PURPOSE:To make it possible to evaluate the charge characteristic of toner with good accuracy, by such simple technique that the toner pattern adhered to an electrode plate is directly transferred and, thereafter, the charge characteristic of the toner is evaluated on the basis of the relation between an adhesion position and reflection density or transmission density. CONSTITUTION:A developer 15 is accelerated by the action of the air stream flowed down through a vertical passage and the effect of gravity and also receives the action of the electric field between opposed electrode plate 11, 12. In this case, the flow speed of the air stream in the vertical passage 11 is set so as to prevent a toner particle from adhering to the electrodes 1, 2. When the distance between the falling start point (x=y=0) of the particle and the electrodes is set to (d), the toner particle with charge (q) is caught at a position of formula y={(mg+Av0)/(qE-W)}d by the electrodes. Therefore, after the toner pattern adhered to the electrode plates are directly transferred, the charge characteristic of the toner can be simply evaluated on the basis of the relation between the adhesion position and reflection density or transmission density with good accuracy.
