Abstract: An absorbent body in which a larger amount of a granular absorbent substance penetrates into the inside of a fiber sheet is produced. A fiber sheet having napped one main surface is supplied to a conveying device and conveyed while the other main surface of the fiber sheet is being sucked through a conveyance surface. A granular absorbent substance is sprayed onto the napped one main surface of the fiber sheet to cause the substance to penetrate into the inside of the fiber sheet in a suction section. A pressure difference increasing device is provided that faces the one main surface of the fiber sheet sprayed with the absorbent substance and being conveyed in the suction section, and that suppresses air from flowing through the fiber sheet inward from the conveyance surface to increase the pressure difference between the conveyance surface side and the opposite side of the fiber sheet.

Abstract: Provided are techniques for providing security for edge computing using location data. A command base location of an entity, an application identifier of the entity, and an expire date for the application identifier are determined. A message generated from the command base location and the application identifier is sent to a location authority. A signed command base location is received based on the command base location being within a jurisdiction of the location authority and a current date being before the expire date. A common key for the command base location is generated using the application identifier and the signed command base location. A public key is generated using the common key. A message is encrypted using the public key to create a cryptographic message. The cryptographic message is sent.
