摘要： Deformation of a gate by Coulomb force generated when operating an electron-emitting device is inhibited by appropriately maintaining relationship between film thickness h of the gate and distance L from an outer surface of an insulating member to an inner surface of a concave portion. According to this, in an electron beam apparatus provided with a laminate-type electron-emitting device, the deformation of the gate is prevented to reduce variation in electron emission characteristics, thereby preventing the element from being broken.

摘要： An inkjet recording head includes a base member, an ink channel unit, a plurality of piezoelectric elements, and a dynamic vibration absorber. The ink channel unit is formed with a plurality of nozzle holes and a plurality of ink pressure chambers. The ink channel unit includes a diaphragm that defines part of each ink pressure chamber. Each piezoelectric element has one end fixed to the base member and another end attached to the diaphragm. Each piezoelectric element generates displacement in a displacement direction for deforming the diaphragm to eject ink droplets through a corresponding one of the plurality of nozzle holes. The dynamic vibration absorber is mounted on the base member for damping vibrations of the base member due to a resonance, the resonance occurring in a frequency range less than or equal to a predetermined frequency.
