Title: Drive device for pulse motor
Inventor: KAWASAKI KAZUNORI
IPC: H02P8/16
Filed: 1982-08-09
Abstract: PURPOSE:To decrease the high speed drive of a pulse motor and the consumption of a power source energy by abruptly attenuating the rise of the coil current of the motor and eliminating the influence which is acted on mutual induction. CONSTITUTION:Switching elements Q1-Q8 are provided at both ends of coils LA, -LA, LB, -LB of a pulse motor PM, the influence of mutual induction voltage which is generated at non-exciting coil is eliminated to accurately detect the exciting coil current and to enable to control it. Further, when the coil is switched form excitation to non-excitation, electromagnetic energy stored in the coil is regenerated in condensers C1-C4 of a drive power source side of reverse phase coil. In this manner, the coil exciting current can be rapidly attenuated, and when reverse phase coil is switched to the excitation, the energy regeneratively stored in the condensers C1-C4 can be utilized for rapid rising of the reverse phase coil current, thereby driving the motor PM at a high speed and decreasing the consumption of the power source energy.

Abstract: PURPOSE:To enable stable control, by applying a disturbance to a feedback control system for a DC motor for winding or sending out yarn, to calculate the dynamic characteristic of the control system and by adjusting a control characteristic to an optimal value on the basis of the result of the comparison of the calculated dynamic characteristic and an objective function. CONSTITUTION:The output of a tension setting unit 2 is applied to an controlled object 12 through addition points 13, 3, a PID controller 4 and an addition point 14. A tension signal is applied as a negative feedback from the controlled object 12 to the addition point 3. The output of a disturbance signal generator 15 is applied to the addition points 13, 14 through a changeover switch 16. The generator 15 is connected to a high-speed Fourier transformer 19 through a changeover switch 17. A cross power spectrum is calculated at 20 from the outputs of the transformer 19 and another high-speed Fourier transformer 18 which receives the feedback signal. A transfer function for the controlled object 12 is calculated at 21 from the cross power spectrum and an automatic power spectrum from a calculator 22. The factors of the control characteristic of a controller 4 are changed on the basis of the transfer function through a stability discriminator 23 etc.

Title: Charging device
Inventor: KATO SHOZO
IPC: H01L31/04
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To improve the utilization factor of storage battery means by easily determining the voltage of the storage battery means for the purpose of overvoltage protection by providing suppressing means for a charging current from a solar cell to the storage battery means below a current level determined by the voltage of storage battery means. SOLUTION: In order to charge a battery 16 from a solar cell 10, a charge current control circuit 50 receives a voltage signal SV from the battery 16 and thus obtains a voltage value from the battery 16 in real time mode. And if the voltage of the battery reaches a predetermined value, a charging current value is restricted by controlling the ON/OFF duty ratio of a switching element Q with PWM control system. By doing this, the voltage value of the battery 16 for overcharge protection becomes almost constant because the battery 16 is not heated and thus the voltage value can be determined easily. Also, the battery 16 can be utilized fully to the constant voltage value, so that the utilization factor of the battery 16 can be enhanced.

Filed: 1987-06-03
Abstract: PURPOSE:To increase the treatment capacity by forming a fixed bed in plural biological reaction vessels connected to each other in series, and packing a microbe carrier module in the preceding to intermediate-stage biological reaction vessels. CONSTITUTION:Raw water 19 is introduced into the first biological reaction vessel 12, anaerobically treated therein, and then aerobically treated in the second, third, and fourth biological reaction vessels 14, 16, and 17. The treated water 20 is discharged from the final sedimentation basin 18.
