A method for manufacturing a liquid-ejection head substrate including a silicon substrate having a supply port for supplying liquid is provided. The essentially-inductive upper part includes a second internal casing of electromagnetic armor, which is disposed radially between the insulant and the external casing. The method may be practiced or supplemented by cauterization of the pyloric sphincter or by suturing the sphincter to narrow the same and may be augmented by inducing flacid paralysis of the stomach by injecting botulinum toxin into the muscle tissue of the antrum or fundus of the stomach.
