Patent number: 12109314Abstract: A soft capsule film composition, comprising: (A) a native gellan gum; (B) one or more hydrophilic polysaccharides; (C) a starch or modified starch; (D) a plasticizer; and (E) water, wherein a gelling agent other than the native gellan gum and the one or more hydrophilic polysaccharides is not an essential component. The soft capsule film composition shortens drying time at room temperature, suppresses the stickiness of the surface of a film sheet, imparts film sheet strength which can withstand continuous production in factory manufacturing with a rotary die filling machine or the like, and enables the manufacture of a good soft capsule with high adhesiveness. For this reason, the soft capsule produced using the soft capsule film composition can be utilized for various uses such as drugs, quasi drugs, cosmetics, and foods.Type: GrantFiled: April 24, 2019Date of Patent: October 8, 2024Assignee: FUJI CAPSULE CO., LTD.Inventors: Yuki Obatake, Yosuke Kondo, Koji Masuda, Kazuhiko Watanabe, Yoshihiko Watanabe

Patent number: 12045000Abstract: An image forming apparatus includes a latent image bearer, an intermediate transferor, a primary transferor, a second transferor, and a cleaning blade. The latent image bearer has a surface onto which a lubricant comprising zinc stearate is supplied. The intermediate transferor has a surface onto which the toner image is transferred, the surface including an adhering region to which the lubricant from the latent image bearer adheres. The cleaning blade cleans the surface of the intermediate transferor including the adhering region, after the toner image is secondarily transferred. In a region outside at least a horizontal A4 sheet passing width on the intermediate transferor, a ratio of a peak area derived from zinc stearate to a peak area derived from the intermediate transferor in a difference spectrum between attenuated total reflection (ATR) infrared absorption spectrums of the intermediate transferor in an unused state and after use is 0.892 or less.Type: GrantFiled: December 13, 2022Date of Patent: July 23, 2024Assignee: RICOH COMPANY, LTD.Inventors: Kazuhiko Watanabe, Hiroshi Nakai
