Publication number: 20240160123Abstract: A developing device includes a development container, a developer carrying member, and a regulation blade. The development container is for containing a non-magnetic one-component developer composed only of the toner. The developer carrying member is manufactured by a polishing method and includes a rotary shaft and a roller portion stacked on an outer circumferential surface of the rotary shaft, and a toner layer is formed on the roller portion. The regulation blade contacts the outer circumferential surface of the roller portion so as to regulate a thickness of the toner layer. When ten-point average roughnesses in a circumferential direction and in an axial direction of the roller portion are indicated as Rz1 and Rz2, respectively, Rz1/Rz2?1.5 is satisfied, and a contact linear pressure of the regulation blade with respect to the roller portion is not less than 15 [N/m] and not more than 40 [N/m].Type: ApplicationFiled: November 6, 2023Publication date: May 16, 2024Applicant: KYOCERA Document Solutions Inc.Inventors: Tomohiro TAMAKI, Masahito ISHINO

Patent number: 11279005Abstract: Provided are a vacuum chuck member and a vacuum chuck method that are capable of suppressing misalignment of a substrate when a wafer having a significant deflection or warpage is chucked and held. In a state in which a wafer W is placed on the upper surface side of a base 1, the pressure in an inner space S1 surrounded by the upper surface of the base 1, the lower surface of the wafer W, and the inner side surface of an inner annular rib 21 is reduced through a first air passage 101. Subsequently, the pressure in an outer space S2 surrounded by the upper surface of the base 1, the lower surface of the wafer W, the outer side surface of the inner annular rib 21, and the inner side surface of an outer annular rib 22 is reduced through a second air passage 102.Type: GrantFiled: February 6, 2017Date of Patent: March 22, 2022Assignee: NGK SPARK PLUG CO., LTD.Inventors: Tomohiro Ishino, Shinya Kikuchi

Patent number: 10836018Abstract: Provided are a substrate holding device and a substrate holding method that enhance the precision of the shape of a substrate while holding the substrate. The substrate holding device includes a first holding member 1, including a plate-shaped first base 10, and a second holding member 2, including a thin plate-shaped second base 20. The first base 10 has an airway 102 extending to the upper surface of the first base 10. The second base 20 has a through hole 202 extending in a thick direction of the second base 20 at a center portion of the second base 20. The second base 20 includes, on the upper surface of the second base 20, multiple protrusions 211, which protrude upward, and at least one annular ridge 212, which protrudes upward in a substantially annular shape coaxial with the first base 10 and surrounds an upper opening of the through hole 202 and the multiple protrusions 211.Type: GrantFiled: December 15, 2016Date of Patent: November 17, 2020Assignee: NGK SPARK PLUG CO., LTD.Inventors: Tomohiro Ishino, Shinya Kikuchi

Patent number: 10468289Abstract: Provided is a substrate holding member that includes a base body and a plurality of protrusions formed on a surface of the base body and that is capable of suppressing generation of particles due to peeling-off or cracking of protective layers of the protrusions. A substrate holding member includes a base body and a plurality of protrusions formed on a surface of the base body. Each of the protrusions includes a base portion and a protective layer, the base portion having a flat upper end surface and being made from a silicon carbide sintered compact, the protective layer being made of silicon carbide. The protective layer includes a region on at least a part of the base portion from an edge of the upper end surface to a lower end of the base portion, the region being exposed along an entire periphery. Preferably, the protective layer is formed so as to cover at least only a part of an upper portion of the base portion, the upper portion including the upper end surface.Type: GrantFiled: December 16, 2016Date of Patent: November 5, 2019Assignee: NGK SPARK PLUG CO., LTD.Inventors: Tomohiro Ishino, Takashi Teshima
