A liquid ejection module includes a pressure chamber, a supply flow channel that supplies a liquid to the pressure chamber, a collection flow channel that collects the liquid from the pressure chamber, a liquid feeding chamber connected to one of the supply flow channel and the collection flow channel, and a connection flow channel connecting the liquid feeding chamber to the other of the supply flow channel and the collection flow channel. The liquid feeding chamber includes a liquid feeding mechanism that circulates the liquid in the supply flow channel, the pressure chamber, the collection flow channel, the liquid feeding chamber, and the connection flow channel. A ratio of a sum of flow channel resistance of the supply flow channel, the pressure chamber, and the collection flow channel relative to flow channel resistance of the connection flow channel is equal to or above 0.5.

Liquid ejection module

In a case where air bubbles exist in ink at the time of circulating the ink within a liquid ejection module, the amount circulating ink runs short and stability of ejection is blocked. The liquid ejection module has: a pressure chamber that communicates with an ejection port and which stores a liquid; an energy generation element that produces energy for causing a liquid to be ejected from the ejection port; a supply flow path that supplies a liquid to the pressure chamber; a collecting channel that collects a liquid from the pressure chamber; a liquid sending chamber that connects to the collecting channel; a connection flow path that connects the liquid sending chamber and the supply flow path; and a liquid sending unit configured to circulate a liquid, and the liquid sending chamber has a continuously inclined structure.

By introducing inequality to the information dispersal/sharing storage method, a ciphertext management method or the like is provided to support novel ciphertext data management. After the ciphertext and key data are each divided, pairs of the divided ciphertext and key data are generated. Specifically, they are one-to-one paired as with conventional techniques. Furthermore, additional one-to-many pairs are generated. The generated one-to-one pairs provide equality as with conventional techniques. When the number of the one-to-one pairs of the divided ciphertext and key data that can be used is equal to or greater than a threshold number, both the ciphertext data and the key data can be reconstructed, and accordingly, the secret data can be decoded. In contrast, even when the one-to-many pairs that can be used is equal to or greater than a threshold number, the ciphertext data and/or the key data cannot be reconstructed. This provides inequality.
