Patent number: 12062663Abstract: As a display device has higher definition, the number of pixels is increased and thus, the number of gate lines and signal lines is increased. When the number of gate lines and signal lines is increased, it is difficult to mount IC chips including driver circuits for driving the gate lines and the signal lines by bonding or the like, whereby manufacturing cost is increased. A pixel portion and a driver circuit for driving the pixel portion are provided on the same substrate, and at least part of the driver circuit comprises a thin film transistor including an oxide semiconductor sandwiched between gate electrodes. A channel protective layer is provided between the oxide semiconductor and a gate electrode provided over the oxide semiconductor. The pixel portion and the driver circuit are provided on the same substrate, which leads to reduction of manufacturing cost.Type: GrantFiled: August 10, 2023Date of Patent: August 13, 2024Inventors: Hidekazu Miyairi, Takeshi Osada, Shunpei Yamazaki

Publication number: 20160082148Abstract: Disclosed is a film which is able to suppress agglutination by being continuously adhered to an adhesion target portion in a biological body while suppressing a position shift. A film includes an adhesive and an adhesion inhibiting layer. The adhesive layer absorbs and maintains a liquid in a plurality of pores which are opened in one film surface and has a capillary force for adhering the adhesive layer to a first-cell group. The adhesive layer is formed of a biodegradable polymer. The adhesion inhibiting layer configures the other film surface, and inhibits adhesion between a second-cell group which is different from the first-cell group and the adhesive layer. In the adhesive layer, the pore is formed not to be penetrated in a thickness direction of the film, and thus the first-cell group and the second-cell group are separated into the one film surface side and the other film surface side.Type: ApplicationFiled: September 11, 2015Publication date: March 24, 2016Applicant: FUJIFILM CORPORATIONInventors: Koju ITO, Souichi KOHASHI, Hidekazu YAMAZAKI, Kenichiro HATA, Katsura SUGAWARA, Eiko GOTO, Masatsugu SHIMOMURA, Hiroshi YABU, Takahito KAWANO

Patent number: 9044899Abstract: A solution of polymer uniformly dissolved into a solvent is prepared in a solution preparing step. The solvent contains good and poor solvent components for the polymer. The solution is discharged from a coating die to a support to be a coating film thereon in a primary body forming step. A water drop generating step and a fluidity decreasing step are performed in parallel with each other while wet air is applied to the coating film. Water drops are generated on a surface of the coating film in the water drop generating step. The good solvent component is evaporated from the coating film to decrease fluidity of the solution for forming the coating film in the fluidity decreasing step. In the water drop evaporating step, dry air is applied to the coating film. The solvent and the water drops are evaporated from the coating film to obtain the porous film.Type: GrantFiled: July 29, 2010Date of Patent: June 2, 2015Assignee: FUJIFILM CORPORATIONInventors: Koju Ito, Hidekazu Yamazaki

Patent number: 8518490Abstract: In a coating zone, a cylindrical tube is soaked in and taken out from a solution, such that a coating film is formed on a curved surface of the tube. In a wet gas zone, while a first gas feeding nozzle having a gas outlet moves in a state where the gas outlet faces an outer peripheral surface of the tube, wet gas is blown toward the coating film through the gas outlet. Water drops are generated on the coating film and grown up. In a dry gas zone, as in the case of the first gas feeding nozzle, while a second gas feeding nozzle having a gas outlet moves, dry gas is blown toward the coating film through the gas outlet. Solvent and water drops are evaporated from the coating film. Pores form from the water drops as a template for the porous material on the coating film.Type: GrantFiled: March 30, 2010Date of Patent: August 27, 2013Assignee: Fujifilm CorporationInventors: Koju Ito, Tsukasa Ishihara, Hidekazu Yamazaki
