  • Publication number: 20240184224
    Abstract: The external additive for toner includes an external additive particle containing: a fine particle A; and a plurality of fine particles B that are each present so as to partially protrude from a surface of the fine particle A, wherein the fine particle A (i) is a particle of an organosilicon compound having a siloxane bond, (ii) has a number-average particle diameter of 0.03 ?m or more and 0.30 ?m or less, and (iii) has an average circularity of 0.90 or more, wherein, when the number-average particle diameter of the fine particle A is represented by DA, and a number-average particle diameter of the plurality of fine particles B is represented by DB, DB/DA is 0.10 or more and 0.63 or less.

  • Publication number: 20240184226
    Abstract: An external additive for toner comprising: a fine particle A containing, as a binder component, an organosilicon compound having a siloxane bond; and a fine particle B that is present on a surface of the fine particle A in a state of being at least partially embedded in the surface of the fine particle A, wherein the external additive for toner (i) has a number-average particle diameter of a primary particle of 0.03 ?m or more and 0.30 ?m or less, and (ii) has a Young's modulus of 10 GPa or more and 30 GPa or less, wherein content ratios, on a number basis, of the following unit (a), unit (b), and unit (c) in the fine particle A based on all silicon atoms present in the fine particle A satisfy the following expressions (1) and (2). (a)+(b)+(c)?0.80??(1) (b)+(c)?0.

  • Publication number: 20240176258
    Abstract: The external additive for toner includes an external additive particle containing: a base particle A; and a plurality of convex forming particles B each configured to form a convex portion on a surface of the base particle A. The base particle A and the convex forming particles B are particles each containing a silicon compound having a siloxane bond, and a chemical bond is formed between the base particle A and each of the convex forming particles B. The base particle A and the convex forming particles B each have a total content of the following unit (a), unit (b), and unit (c) of 80 mass % or more and 100 mass % or less: where R1 and R2 each represent an alkyl group having 1 or more and 6 or less carbon atoms.

  • Patent number: 10687989
    Abstract: Disclosed is a disposable wearing article which can effectively prevent lateral leakage of body exudates by planarly fitting an outer flap positioned laterally outside of an absorbent core included in an absorbent panel on the body of a wearer with the outer flap pulled laterally outside of the article. In the article, the absorbent panel includes the absorbent core extending to front and rear waist regions centering on a crotch region and a pair of outer flaps extending laterally outside of the absorbent core. At least the front waist region of the front and rear waist regions includes a waist elastic area which is elastically contractible in the lateral direction and a pair of elastic strips which is elastically contractible, and the elastic strips each have an outer fixing end fixed on the body facing surface of the chassis.

  • Patent number: 8725701
    Abstract: Systems and methods are provided that perform data validation in real time. By uploading the source data from spreadsheets or entering the data directly into an application, the required validations can be run and reported in real time. Users can then either extract the data back into spreadsheets for manipulation, and then re-upload it, or correct the data directly within the application. Once the data set has passed all validations, it is then passed to the technical team for upload into the transactional system.
