IPC: H03H9/215
Filed: 2000-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a very small vibrator that secures a sufficient mount area at a support part while properly keeping the ratio of a length to a width without degrading the performance in comparison with a tuning fork.

Title: Nozzle plate and its manufacturing method
Inventor: TEZUKA SHINJI
IPC: B41J2/01
Filed: 2000-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a nozzle plate having a nozzle hole tapered to decrease the diameter gradually in the ink ejecting direction, and its manufacturing method. SOLUTION: The nozzle plate 1 has a water repellent layer 3 formed on the surface of a plate substrate 2 and a nozzle hole 4 is made through the plate substrate 2 and the water repellent layer 3.
