Patent number: 8173336Abstract: The purpose of the present invention is to provide a method for transferring a pattern of a circuit pattern precursor formed of electroconductive particles containing no resin component onto an objective substrate with high transfer efficiency while retaining a pattern shape. A method of transferring the circuit pattern precursor formed from an conductive particle dispersed solution on a dielectric thin film body includes the steps of: temporarily removing a liquid film remaining around the circuit pattern precursor right after a development step; subsequently re-electrifying the electroconductive particle pattern by supplying a solvent again to the circuit pattern precursor; and then electrostatically transferring the pattern onto the objective substrate through electrophoresis in the solvent.Type: GrantFiled: July 27, 2007Date of Patent: May 8, 2012Assignee: Hitachi, Ltd.Inventors: Yuichiro Sano, Toru Miyasaka

Patent number: 8039182Abstract: An object is to improve the adhesion strength between a circuit pattern and its substrate without increasing the resistance value of the circuit pattern in preparation of a circuit pattern holding substrate. A circuit pattern formation device 100 forms, after forming a precursor circuit-pattern 12 in the surface of a dielectric thin film body 4, a circuit pattern 14 onto a target substrate 23 from the dielectric thin film body. After forming an electrostatic latent image 2 in the upper surface of the dielectric thin film body, the electrostatic latent image is exposed using an exposure unit 3 to prepare a pattern. A development apparatus 7 supplies a conductive particle dispersion solution 6 to this pattern to form a precursor circuit-pattern. By energizing the circuit pattern holding substrate 8, in which an adhesive layer 22 is formed, the precursor circuit-pattern is temporarily transferred to the circuit pattern holding substrate.Type: GrantFiled: July 3, 2007Date of Patent: October 18, 2011Assignee: Hitachi, Ltd.Inventors: Yuichiro Sano, Toru Miyasaka

Publication number: 20050129427Abstract: For a conventional image forming apparatus, since a waveform in a phase opposite that of a rotation change waveform is applied to a drive motor to rotate a photosensitive member, a correction to cancel the rotation change is also performed for a sudden rotation change of the photosensitive member, or for a high frequency change in the noise component generated by a rotation detector. As a result, since the drive motor can not be smoothly rotated, and since the drive torque of the drive motor is not stabilized, small vibrations always occur in the photosensitive member and cause image deterioration, such as a jitter or banding. Therefore, according to the invention, cycling due to the eccentricity of the photosensitive member is represented by using a continuous repetition function, and the waveform in the opposite phase is employed as a drive instruction value for the driving unit. With this arrangement, smooth rotation of the driving unit can be obtained, and the offsetting of the change is performed.Type: ApplicationFiled: September 30, 2004Publication date: June 16, 2005Inventors: Yasushi Kinoshita, Toru Miyasaka, Yuji Uozaki

Publication number: 20050073572Abstract: A photo conductor and exposure integrally-formed type apparatus is of a drum type, and is rotated at a fixed speed in a clockwise direction. A residual toner attached to a surface of the photo conductor is removed by a cleaner, and a charging device applies a charge load uniformly to a surface of the photo conductor layer so as to charge the photo conductor layer. A light emitting layer exposes the photo conductor layer in a luminous area from an inner side, and forms a latent image on the photo conductor layer. The latent image formed on the photo conductor layer is developed by toner by a developing device, and forms an apparent image by the toner attached to the latent image. Further, the toner image appearing on the photo conductor layer is transferred on a recording medium by a transfer device. Accordingly, since no movement exists between an exposure point and an image forming point in the luminous area, an image deterioration caused by the movement is not generated.Type: ApplicationFiled: June 24, 2004Publication date: April 7, 2005Applicant: Hitachi, Ltd.Inventors: Masahiro Yagi, Taichiro Yamashita, Toru Miyasaka, Kenji Asuwa, Shintaro Yamada
