Patent number: 12157306Abstract: A liquid discharge apparatus to apply liquid to an application surface includes a head and processing circuitry. The head applies the liquid discharged from a nozzle to the application surface. The processing circuitry outputs abnormal discharge information of the nozzle. The abnormal discharge information is detected based on a shape of the liquid applied to the application surface.Type: GrantFiled: October 14, 2022Date of Patent: December 3, 2024Assignee: Ricoh Company, Ltd.Inventors: Takahiko Sugiura, Takayuki Ito, Kenji Kamei, Taito Omura, Hikaru Fukazawa

Patent number: 11679603Abstract: A liquid discharge apparatus includes a conveyance roller, a liquid discharge head, and a control device. The control device controls the head to discharge liquid onto a medium X times in the main scanning direction and Y times in the sub-scanning direction and controls the roller such that a position of a droplet on the medium discharged by an m-th discharge and a position of another droplet on the medium discharged by an (m+Y)-th discharge are same in the sub-scanning direction, where m is an integer not smaller than one and not greater than ((X?1)×Y). Where P is a circumferential length of the roller and L is a difference in a conveyance distance in the sub-scanning direction when the m-th discharge is compared with the (m+Y)-th discharge, the following relation is satisfied: L=(n+(??/2?))×P, where |????|<60° and n is an integer.Type: GrantFiled: October 8, 2021Date of Patent: June 20, 2023Assignee: RICOH COMPANY, LTD.Inventors: Yosuke Saito, Daiki Marumo, Takahiko Sugiura, Shotaro Takeuchi

Patent number: 11623455Abstract: A liquid discharge apparatus includes a color component divided data generation unit, a dot data generation processing unit, and a dot data segmentation processing unit. The color component divided data generation unit generates color component divided data from image data. The dot data generation processing unit applies a dot data generation mask to the color component divided data to generate dot data. The dot data segmentation processing unit applies a segmentation mask to the dot data to generate scan data. A width of the segmentation mask in a main scanning direction is different from a width of the dot data generation mask in the main scanning direction.Type: GrantFiled: October 6, 2021Date of Patent: April 11, 2023Assignee: Ricoh Company, Ltd.Inventors: Kimito Abe, Shotaro Takeuchi, Masanori Hirano, Takayuki Ito, Takahiko Sugiura, Daiki Marumo, Kyohei Hamada

Publication number: 20070170659Abstract: A metal gasket capable of preventing the occurrence of cracks in a stopper while employing a wave-shaped stopper, improving the contact pressure balance around the bead to enhance the engine performance, and improving the durability of the stopper. The metal gasket is constituted by a gasket component sheet having an opening formed to face a combustion chamber, and the gasket component sheet is provided with a combustion chamber bead surrounding the opening. An inner circumference side stopper lower than the height of the combustion chamber bead is formed along the combustion chamber bead in a portion between the combustion chamber bead and the opening such that at least a section of each wave where stress amplitude is large becomes thin, a thin portion and a thick portion are arranged alternately in each wave, and the hardness of the thin portion is higher than that of the thick portion.Type: ApplicationFiled: February 23, 2007Publication date: July 26, 2007Applicants: Koichi Hatamura, KOKUSAN PARTS INDUSTRY CO., LTD.Inventors: Koichi Hatamura, Takashi Suzuki, Hiroyuki Ogino, Takahiko Sugiura, Yasuyuki Okudaira, Takeshi Wakuda, Reiji Mahigashi, Keisuke Umehara, Masahisa Kumashiro
