Title: Ink-jet recording apparatus
Inventor: MAKITA HIDEYUKI
IPC: B41J2/055
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To improve discharge stability for ink drops at the time of high-frequency driving, by fixing a piezoelectric element of an ink-jet head to a substrate with an adhesive having elasticity. SOLUTION: An adhesive 14 used for bonding a piezoelectric element 12 and a substrate 11 has elasticity. When such a pulse-like driving waveform is applied after ink is filled in an ink liquid chamber that suddenly decreases a volume of a pressure liquid chamber 35 to discharge ink drops from a nozzle 38, the piezoelectric element 12 can be shifted efficiently in a minus direction. Accordingly, ink drops can be discharged stably without ink refill performance deteriorated even when a driving frequency is high. Further, since the volume of the pressure liquid chamber 35 is increased before the ink is filled, a volume change at the discharge of ink drops is enlarged, thereby enabling reduction of a driving voltage for the discharge of ink drops.

Title: Magneto-optical information recording and reproducing device and its production method
Inventor: ISOBE TAMI
IPC: G02B6/122
Filed: 1991-10-03
Abstract: PURPOSE:To reduce end point position fluctuation of guided optical wave caused by the fluctuation of the light source wave length, prevent the reduction in detection efficiency of Fo signals and to improve an S/N by using a guided wave path mirror in a guided wave path conversion element. CONSTITUTION:Light beams reflected by guided wave mirrors 7a and 7b are detected by photodetectors 8a and 8b. When a magneto-optical information recording medium 5 is located at a focus position against an objective lens 4, each element is placed so that the reflected beams from the mirrors 7a and 7b are converged at the center of the detectors 8a and 8b. Outputs Pa and Pb of the detectors 8a and 8b are adjusted to be made equal and Fo signals are obtained as the difference of these outputs. The signals become smaller than zero if the medium 5 moves away from the focus of the lens 4 and have a tendency to converge compared with a focused condition, and if the medium moves toward the focus, the signals become larger than zero and have a tendency to diverge. As can be seen above, a focus signal detection section is configured by the combination of waveguides and detectors, thus, no focus position fluctuation occurs due to the wave length fluctuation of the light source and the detection sensitivity is not degraded.

Title: Vector controller for induction motor
Inventor: KOKETSU MASATOSHI
IPC: H02P23/07
Filed: 1994-10-24
Abstract: PURPOSE: To obtain a vector controller for operating an induction motor stably without causing any failure under a steep deceleration state within a constant output range. CONSTITUTION: ACR sections 10, 11 for controlling the primary current to a target value in vector control has variable gains. The ACR gain is switched, at a correction coefficient generating section 15 and an ACR gain control section 16, to a high gain under high speed region and to a constant gain under low speed region depending on the detection speed of an induction motor IM. Consequently, when the induction motor IM is decelerating steeply within a constant output range, the response is quickened in a high speed region and hunting is prevented in a low speed region to prevent run-out of vector control thus realizing a good control. Furthermore, a predetermined limit is imposed by the output of a drive/regeneration discriminator 18 to the primary voltage V1 generated from a PWM signal generating section 4 at the time of regeneration.  This constitution prevents overcurrent being generated under step-out state thus preventing failure.
