Title: Servo control circuit
Inventor: SEKIGUCHI HIDENORI
IPC: B23Q5/36
Filed: 1989-09-12
Abstract: PURPOSE:To prevent a servo motor from generating heat in its static state by providing the servo control circuit with a control deviation arithmetic means for calculating a deviation value, detecting a positioning section from the time of 'zero' deviation value, setting up a minimum integration value, and outputting the set value to a PID control means. CONSTITUTION:In the control deviation arithmetic means, a zero deviation detecting circuit 15 detects 'zero' deviation value (e) between a set point (r) and a fed back current position (y), a timer 16 detects that the 'zero' deviation value is continued for a regulated value or more and a section detecting circuit 17 detects a positioning section from the regulated time. A minimum integration value setting circuit 18 compares the minimum integration value stored in each positioning section with the integration value at that time, registers the smaller value as the minimum integration value in the section and sets up the registered value as the integration value at the point of time. By this constitution, the integration value of an integrator 13 to be a PID control means is changed to the minimum integration value, so that the manipulated variable is reduced after positioning and the servo motor can be prevented from generating heat in static state.

Abstract: PROBLEM TO BE SOLVED: To easily add the captions to the reproduced animations and also to easily correct, add and delete the caption data as necessary by superimposing the caption data on the reproduced animations synchronously with the displayed images when the animation data are reproduced. SOLUTION: The animation data stored in an animation data file 1 and an animation disk 2 are reproduced into the time series animations by an image reproduction device 3 and shown on a display device 7. At the same time, the captions are superimposed on the animations at an image synthesizing part 4. When the part 4 receives the caption data (b) on the still pictures which are expanded into images from a caption data management part 5, the part 4 superimposes the data (b) on the animations which are successively inputted from the device 3 in the reception timing of the data (b) for 5 to 10 seconds, for example, which are needed for reading a caption. As a result, both animation and caption data can be managed separately from each other and the captions can be easily added to the reproduced animations.

Abstract: PURPOSE:To remove the resistance in a suction flow passing and air bubbles produced during suction and improve measurement precision by sucking a suction flow passage system for a sample through a minimum flow passage, and injecting the sample into a measuring pipe and adding it to a column. CONSTITUTION:When a nozzle 15 is connected to a syringe 7 and a sample is sucked by a set amount, the sample is sucked to the nozzle 15 and a change groove part 16. A specific amount of eluate is sucked through a changeover valve 10 to move the sample reserved in the nozzle 15 and groove part 16 beyond the changeover groove 16. Then, the valve 10 is changed over to form a flow passage of the nozzle 15, measuring pipe 6, and syringe 7, and then the sample discharged from the syringe 7 is pressed in the measuring pipe 6. At this time, the eluate in the pipe 6 is discharged into a cleaning container 14 to clean the internal wall of the nozzle 15. When the valve 10 is switched to a flow passage of a pump 2 and the column 3, the sample in the pipe 6 is added into the column 3. Consequently, the sample is sucked to the sample suction flow passage through a minimum flow passage by the series of introducing operations without being passed through the large-capacity flow passage of the pipe 6.
