Publication number: 20230302823Abstract: The anti-drop members 7l and 7r are provided to each of the air turn bars 6u and 6l, and the respective anti-drop peripheral surfaces 711 of the anti-drop members 7l and 7r adjoin the support peripheral surface 611 of each of the air turn bars 6u and 6l. In this configuration, on the occurrence of oblique traveling of the printing medium M, the printing medium M is deviated from the support peripheral surface 611 of each of the air turn bars 6u and 6l to the anti-drop peripheral surface 711 of the anti-drop member 7l or 7r. Specifically, the anti-drop peripheral surface 711 of each of the anti-drop members 7l and 7r allows the printing medium M to be supported while providing the clearance ? from the front surface M1 of the printing medium M deviated by the oblique traveling.Type: ApplicationFiled: February 13, 2023Publication date: September 28, 2023Inventors: Kenta Hiramatsu, Yoshikuni TAKEICHI, Ryota UEMURA

Patent number: 11590774Abstract: The wind velocity of the air injected by the air-blow dryers 7a, 7b is lower than that of the air injected by the air-blow dryers 7c, 7d. That is, since a large amount of moisture remains on the front surface M1 of the printing medium M passing through the air-blow dryers 7a, 7b, the printing medium M is dried while the flow of the aqueous inks is suppressed by injecting the air at a lower wind velocity. On the other hand, the moisture decreases on the front surface M1 of the printing medium M dried by the air-blow dryers 7a, 7b and the fluidity of the aqueous inks is reduced. Accordingly, the drying of the printing medium M is promoted by injecting the air at a high wind velocity to the printing medium M passing through the air-blow dryers 7c, 7d.Type: GrantFiled: March 4, 2021Date of Patent: February 28, 2023Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Kenta Hiramatsu, Yoshikuni Takeichi, Takeshi Matsuda, Keisuke Hirai, Ryota Uemura

Patent number: 11453227Abstract: In the air-blow dryers 7a, 7b, the back surface M2 of the printing medium M is supported by the rollers 74 while the hot wind is injected from the nozzles 76u to the front surface M1 of the printing medium M. By extending the printing medium M along the rollers 74, the evaporation of the moisture can be promoted by the hot wind while the formation of creases of the printing medium M is suppressed against the influence of the temperature distribution caused by the latent heat of the moisture on the printing medium M. After a certain amount of the moisture is evaporated, the temperature of the printing medium M becomes relatively uniform. In the air-blow dryers 7c, 7d, the printing medium M is dried by injecting the hot wind to the printing medium M from the nozzles 76l and 76u from both sides.Type: GrantFiled: March 4, 2021Date of Patent: September 27, 2022Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Ryota Uemura, Keisuke Hirai, Yoshikuni Takeichi, Takeshi Matsuda, Kenta Hiramatsu

Patent number: 8920522Abstract: A negative-electrode active material layer having an uneven pattern is formed on a surface of a copper foil as a negative-electrode current collector by applying an application liquid by a nozzle-scan coating method. Subsequently, an application liquid containing a polymer electrolyte material is applied by a spin coating method, thereby forming a solid electrolyte layer in conformity with the uneven pattern. Subsequently, an application liquid is applied by a doctor blade method, thereby forming a positive-electrode active material layer whose lower surface conforms to the unevenness and whose upper surface is substantially flat. A thin and high-performance all-solid-state battery can be produced by laminating an aluminum foil as a positive-electrode current collector before the application liquid is cured.Type: GrantFiled: September 22, 2010Date of Patent: December 30, 2014Assignee: Dainippon Screen MFG.

Publication number: 20130071552Abstract: In a technology for manufacturing a battery electrode by applying an application liquid containing an active material, stripe-shaped pattern elements are formed at narrower intervals than before while contact between the pattern elements is avoided. While a nozzle 21 including a multitude of discharge openings in an X-direction is moved to scan in a Y-direction relative to a base material 110, an application liquid containing an active material is discharged from the respective discharge openings and applied to the base material 110. Between pattern elements 221 formed by a first scanning movement, pattern elements 222 are formed by applying the application liquid anew by a second scanning movement. By making the start positions of the pattern elements 221, 222 different in a scanning direction (Y-direction), contact between the pattern elements resulting from the spread of the application liquid at pattern element start ends is prevented.Type: ApplicationFiled: July 24, 2012Publication date: March 21, 2013Inventors: Kuniko TERAKI, Kenta HIRAMATSU, Takeshi MATSUDA, Koji FURUICHI, Masakazu SANADA

Publication number: 20130067729Abstract: In a technology for manufacturing a battery electrode by applying an application liquid containing an active material, stripe-shaped pattern elements are formed at narrower intervals than before while contact between the pattern elements is avoided. An application liquid containing an active material is applied onto a base material 11, which will become a current collector, by a nozzle-scan coating method, thereby forming stripe-shaped active material pattern elements P1, P3, P5, . . . parallel to each other and extending in a Y-direction. After liquid components are volatilized from the application liquid and spread base parts of the pattern elements are shrunk, pattern elements P2, P4, P6, . . . are formed by applying the application liquid in stripes between the already formed pattern elements. In this way, it can be prevented that the base parts approach each other and the pattern elements touch each other when the adjacent patterns are simultaneously formed.Type: ApplicationFiled: June 22, 2012Publication date: March 21, 2013Inventors: Kuniko TERAKI, Kenta HIRAMATSU, Takeshi MATSUDA, Koji FURUICHI, Masakazu SANADA
