Abstract: PURPOSE:To improve the controllability and the responsiveness of a state feedback control system by selecting the coefficient of a state feedback gain element in order to cancel the equivalent disturbance input with use of an equivalent disturbance observer which uses the torque command input value and the control state value as its input. CONSTITUTION:A state feedback controller defines the difference between the target value mu and the state feedback value mu' obtained by multiplying the feedback gain F by a controlled state variable (x) as a manipulated variable of a controlled system. The feedback gain elements f11, f12 and f13 of a state feedback gain matrix are decided so that the disturbance TL, i.e., the target input of the controlled system is eliminated with use of an equivalent disturbance observer. Thus the disturbance TL is eliminated by the equivalent disturbance observer output TL. Then it is possible to attain a system equivalent to that where any disturbance is inputted to the controlled system.

IPC: B41J2/015
Filed: 1984-11-09
Abstract: PURPOSE:To make the realization of a compact drive circuit consuming low electric consumption possible by decreasing a drive voltage of an ink jet recorder. CONSTITUTION:A pulse voltage corresponding to a pixel is applied to a multinozzle ink jet recorder utilizing static power. Then the pulse voltage corresponding to an image signal is applied to an independent electrode provided near each ink discharging port. The figure shows a voltage waveform (a) applied to a common electrode and a voltage waveform (b) of one of the independent electrodes as an example. Experiments were conducted based on the voltage of the voltage pulse represented by Vpd=-350V and the pulse width by Pwb=50mus. Consequently it was found that even if a signal voltage V to be applied to the independent electrode were decreased to 300V, the response and gradation are favorably comparable to those of the conventional recorder.

Title: Level converting circuit
Inventor: TSUKADA HIROMI
IPC: H03K5/003
Filed: 1988-09-22
Abstract: PURPOSE:To make the logic level stable and to suppress the production of a DC current by providing a P-channel MOSFET to a base of an emitter follower output transistor(TR) and an N-channel MOSFET to the emitter in a differential TR circuit. CONSTITUTION:An input signal is given to a gate of P-channel MOSFETs Q1, Q3 and a gate of N-channel MOSFETs Q2, Q4 with a level difference by a voltage drop of resistors R3, R4 and a hase-emitter voltage VBE of TRs T3, T4 with respect to an output signal of a differential TR circuit. Thus, even when an ECL level to be level-converted is at a midpoint potential, the conductance of the FETs Q1, Q3 and the FETs Q2, Q4 is comparatively decreased. Then a DC current flowing through the FETs Q1, Q2 and Q3, Q4 is limited. Since the ratio of the conductance of the FET Q1 turned on at a low level is adopted larger, the stability of the operation is attained.
