Title: Electrochromic element driving system
Inventor: MIZUNO YOSHIKI
IPC: G09F9/30
Filed: 1991-05-31
Abstract: PURPOSE:To eliminate a remaining color, a color irregularity, etc., and to improve cycle characteristics by connecting a capacitor to an electrochromic element(ECD) in series. CONSTITUTION:The capacitor C is connected to the ECD1 in series. An ON/OFF device 2 consisting of a timer, etc., turns ON and OFF a switch S1 at intervals of, for example, five to apply and cease a DC voltage and then the ECD1 is repeatedly fed with electricity and discharged through the capacitor C. Namely, the voltage of a power source E is applied to the ECD1 as it is right after the switch S1 is turned OFF, but the capacitor C is charged, so the voltage applied to the ECD1 drops by a rise in the charging voltage according to an exponential function and a current which decreases according to the exponential function flows between the electrodes to cause coloration by oxidation and reduction. When the switch S1 is turned ON five minute later, the charging voltage of the capacitor C is applied in a reverse direction and the energy accumulated in the ECD1 and capacitor C is discharged at the same time to cause decoloration.

Title: Hydraulic drive device
Inventor: EGARASHI SATOO
IPC: F15B11/00
Filed: 1977-10-31
Abstract: PURPOSE: To prevent the thrust to be exerted upon an operating point from becoming impulsive not excessive at the leading end of the hydraulic cylinder of a drive device and to simplify the construction and reduce the size of the drive device.  
     CONSTITUTION: When the piston rod 15b of a hydraulic cylinder 15 reaches a front end, oil begins to be accumulated. Since, in this instance, a change-over valve 21 holds its position 21a while providing communication between the head and rod sides of the cylinder 15, the thrust generated at the cylinder 15 corresponds to the difference in the pressure receiving areas between the head and rod sides of the cylinder 15. When a pressure reaches a preset level, an electric motor 1 is stopped by a pressure switch 28 so that the pressure at the rod side is gradually reduced by the lead in a pump 2 and from the valve 21. After that, the hydraulic energy accumulated in an accumulator 17 holds the cylinder 15 at a preset level.

Filed: 1983-07-19
Abstract: PURPOSE:To simplify the circuit constitution by performing secant correction, coordinate conversion, and phase difference correction collectively in one place in an azimuth elevation mount four-converging reflective mirror beam feeding Cassegrain antenna. CONSTITUTION:Azimuth and elevation angle error signals are read through error signal input circuits 3 and 4, and an azimuth thetaAZ and an actual elevation angle thetaEL of the antenna are read from input circuits 5 and 6, and they are operated by a microprocessor 9. Azimuth and elevation angle error signals which are detected with new rotated azimuth-elevation coordinates are subjected to coordinate rotation by DELTAtheta=thetaAZ+thetaEL to convert them to azimuth and elevation angle error signals on reference azimuth-elevation coordinates, and cosecthetaEL is multiplied by the azimuth angle error signal to perform secant correction. Coordinate rotation is performed by DELTAthetaS, which is a phase difference between the sum signal and the error signal generated by route switching of a low noise amplifier or frequency switching of a beacon signal, thus compensating the phase error.
