Title: Excitation controller for synchronous machine
Inventor: TANAKA SEIICHI
IPC: G05B13/02
Filed: 1991-08-26
Abstract: PURPOSE:To obtain control constants of AVR automatically by operating the control constants based on set machine constants and control constants of an exciting machine and a synchronous machine. CONSTITUTION:A control constant operating section is internally set with a zero-cross frequency wc and a phase margin thetam and externally set with a gain KG, a time constant TG, a gain KE, and a time constant TE. Upon turn ON of a tuning switch 105, operations are executed according to formulas (I), (II), (III). In other words, forward transfer function is determined by formula (I.) In order to provide the transfer function with characteristics of zero-cross frequency wc and phase margin thetam, constant Tlag at phase compensating section must be determined by formula (II). Furthermore, gain g1 at an amplifying section is determined by formula (III). Consequently, control constants K1, Tlead, Tlag are operated automatically by setting the gain KG and time constant TG of a synchronous generator 1 and the gain KE and the time constant TE of an exciter.

Title: Ink bag for ink cartridge
Inventor: SATO KAZUHIKO
IPC: B41J2/175
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent a restoring force within an ink bag from being hindered by preventing a part of a sheet reinforcing member from joining with the ink bag, in the ink bag for an ink cartridge comprised of the ink bag made of an elastic material such as rubber and a highly flexible sheet reinforcing member. SOLUTION: When ink in an ink bag 3 is consumed due to discharge from a nozzle 7 for conducting dot recording or ink discharge to a recording medium, the amount of ink in the ink bag 3 decreases and thereby increases the distortion of the ink bag 3. However, since a sheet reinforcing member 4 is pasted only by joints 5 at both ends in the longitudinal direction, the ink bag 3 and the sheet reinforcing member 4 have a high degree of freedom, the sheet reinforcing member 4 does not hinder the restoring force of the ink bag 3. Therefore, negative pressure in the ink bag 3 can be maintained stable from the start to end amount of remaining ink in the ink bag 3.
