Provided is a cell tissue producing method including: a cell adhesive portion forming step of forming a cell adhesive portion formed of a cell adhesive material and having a predetermined shape at a predetermined position over a substrate having a cell non-adhesive surface; and a cell locating step of discharging a cell suspension containing at least cells and a cell drying inhibitor onto the cell adhesive portion in the form of a liquid droplet to locate the cells.

Cell tissue producing method and apparatus, and non-transitory recording medium storing cell tissue producing program

Provided is a liquid jet head, including a flow path including a first member, a resin layer, and a second member, wherein the resin layer contains a cured product of a resin composition containing an epoxy compound represented by General Formula (1), a polythiol compound having 2 or more thiol groups in a molecule thereof, and a specific imidazole compound, where in General Formula (1), L is an integer of 0 or greater but less than 3, m is a positive number of 0.1 or greater but less than 50, Rrepresents any one of a hydrogen atom, and an alkyl group having 1 to 4 carbon atoms, and Rrepresents a substituent represented by a formula below where Rand Reach represent any one of hydrogen atom, and a non-substituted or fluorine-substituted methyl group, and n is an integer of 4 to 12.

Liquid jet head and method for producing same, and liquid jet apparatus and image forming apparatus

A liquid ejection head includes channel forming members and a surface treatment film. The channel forming members are joined to each other via an adhesive agent to form a channel for liquid. The surface treatment film is formed on a surface of at least one of the channel forming members. The surface treatment film is an oxidized film including Si. The oxidized film further includes a transition metal forming a passive film.

Liquid ejection head and image forming apparatus incorporating same

A liquid ejection head is provided. The liquid ejection head includes a nozzle substrate to eject a droplet of a liquid from a nozzle thereof; a surface treatment layer, which is located on the surface of the nozzle substrate and which is an oxide layer including silicon (Si) and a transition metal capable of forming a passive layer; and an organic liquid repellent layer located on the surface treatment layer.
