Title: Liquid drop ejector, recording head and ink jet recorder using it
Inventor: MASUBUCHI FUMITO
IPC: B41J2/055
Filed: 2000-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce mutual interference between adjacent pressurized liquid chambers and loss of ejection efficiency by reducing a force being transmitted to a barrier wall through a diaphragm when an actuator is driven.

Title: Synchronizing separator circuit
Inventor: CHIBA MASAHIKO
IPC: H04N5/08
Filed: 2000-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain a synchronous signal with large-enough output level even if the input level of the synchronous signal is low. SOLUTION: When a synchronous signal is applied to the emitter of a first transistor 1 via a coupling capacitor 21 and the collector current changes by only ΔIE, the current is changed by only n×ΔIE in a fourth transistor 4, and by only m×ΔIE in a sixth transistor 6. At the same time the current of m×ΔIE is made to flow in a fifth transistor 5 by the current mirror effect. As a result, the output current becomes (n-m)×ΔIE, providing a synchronous signal with a large-enough level.
