Patent number: 11949090Abstract: A winding-start region that is closer to a winding-start side than a positive electrode core exposed part has positive electrode mixture unit amounts of a positive electrode inner mixture layer and a positive electrode outer mixture layer that are approximately uniform or increasing toward a winding-end side in the winding direction. A winding-start facing region has negative electrode mixture unit amounts of a negative electrode inner mixture layer and a negative electrode outer mixture layer that are approximately uniform or increasing toward the winding-end side. The positive electrode inner mixture layer and the positive electrode outer mixture layer each have a positive electrode mixture unit amount that differs at two or more locations, excluding the positive electrode core exposed part. The negative electrode inner mixture layer and the negative electrode outer mixture each have a fluctuating part where the negative electrode mixture unit amount fluctuates toward the winding-end side.Type: GrantFiled: February 26, 2019Date of Patent: April 2, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hajime Nishino, Yasuhiro Sugaya, Takanori Maruo

Patent number: 11827486Abstract: An image forming apparatus includes a conveyance unit, a detection unit, and a determination unit. The conveyance unit conveys a sheet. The detection unit detects a sound that emanates when the conveyance unit operates. The determination unit performs state determination. In a case where a volume of a sound detected by the detection unit is not higher than or equal to a predetermined sound volume, the determination unit determines that the conveyance unit is not normally operating. In a case where the detected sound volume is higher than or equal to the predetermined sound volume, the determination unit determines that the conveyance unit is normally operating.Type: GrantFiled: March 31, 2020Date of Patent: November 28, 2023Assignee: Canon Kabushiki KaishaInventors: Kosuke Ogino, Hajime Sugaya, Hiroshi Hagiwara

Patent number: 10042280Abstract: An image forming apparatus includes an apparatus body having an opening, an image forming unit, a storage portions, a moving unit, and a sensing unit. The storage portions store, inside the apparatus body, a sheet having an image. The moving unit can move the sheet stored in each storage portion and stop the sheet in an exposure state where the sheet is exposed outside the apparatus body through the opening. The moving unit moves a first stored sheet and stops the first sheet in the exposure state. If the sensing unit enters a state in which the first sheet is not sensed from a state in which the first sheet is sensed, the moving unit moves a second stored sheet and stops the second sheet in the exposure state where the second sheet is exposed outside the apparatus body through the opening through which the first sheet is exposed.Type: GrantFiled: April 28, 2015Date of Patent: August 7, 2018Assignee: Canon Kabushiki KaishaInventors: Takafumi Hirose, Hajime Sugaya

Color image forming apparatus, and program and method of controlling a color image forming apparatus
Patent number: 7542690Abstract: In a color image forming apparatus, a color mode is switched from a full color mode to a single color mode as follows. When the length of an image of a last page in the full color mode is less than the distance from a first-transferring position of a most downstream image forming station to a second-transferring position, if the time interval from arrival of the trailing end of an image of a page immediately previous to the last page at the second-transferring position to arrival of the leading end of the image of the last page at the second-transferring position is longer than the time needed to separate color image forming stations from the second image carrying medium, then the separating operation is started when the trail end of the image of the page immediately previous to the last page in the full color mode reaches the second-transferring position.Type: GrantFiled: August 25, 2008Date of Patent: June 2, 2009Assignee: Canon Kabushiki KaishaInventors: Hajime Sugaya, Hiroaki Ogata
