Title: Method and apparatus for reducing water dip in ion chromatography using elution liquid containing sodium carbonate
Inventor: MIZUSAWA SHINYA
IPC: B01D15/08
Filed: 1985-05-02
Abstract: PURPOSE:To obtain analysis accuracy with a high sensitivity, by sending a eluted liquid with a low conductivity effectively cleared of carbonic acid to an electric conductivity detector. CONSTITUTION:A sample is injected into an elution liquid containing sodium carbonate and the eluted liquid is made to flow into a carbonic acid permeating tube 2 through a conduit tube 10 and a joint 6 from a removing column not illustrate to be introduced into a water dip reducer 1. As the tube 2 is previously immersed into a carbonic-acid-removing liquid 4 which is controlled to an ideal with a temperature adjuster 5 within an aqueous solution tank 3, the carbonic acid in the eluted liquid flowing through the tube 2 is transferred into the removing liquid 4 through a partition of the tube 2. Then, the eluted liquid with a low electric conductivity containing no carbonic acid flowing down to a detector section 11 can be sent to an electric conductivity detector 12. This enables the reduction of the water dip appearing in the chromatogram while assuring analysis accuracy with a high sensitivity.

Title: Up/down positioning device
Inventor: MIYATA MASAKAZU
IPC: G05D3/00
Filed: 1987-04-17
Abstract: PURPOSE:To allow a servomotor having a required minimum motor output to correspond to the variation of a load by allowing the pressure of a balance cylinder to follow the variation of the load. CONSTITUTION:When the capacity of the load 8 is drastically raised by disturbance or the like, the variation of motor current of the servomotor 2 is detected by a detection part 10. A pressure switching comparator 11 sends a high pressure signal to an operation part 12 based on the detected signal and drives a switching valve 12a to switch air supplied to the balance cylinder 9 from a low pressure to a high pressure. When the air supplied to the cylinder is turned to the high pressure, external force applied by the cylinder 9 is increased and is made to instantaneously correspond to a change in the weight of the load 8. Since the variation of the load 8 instantaneously corresponds to the air pressure of the cylinder 9, the motor current and rotational frequency of the motor 2 are converged to the original states and stabilized under a constant voltage.

Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To reduce the spate factor of a circuit and also to simplify frequency adjustment process by constituting a frequency adjusting part of resistors, capacitors and a variable capacitor. SOLUTION: Electrostatic capacity based on a voltage decided by the resistors R1 and R2 appears in a variable capacitor VC and synthetic capacity Ccd by the capacitors C4 and C5 and variable capacitor VC is obtained in a second serial circuit. When the ratio of the resistors R1 and R2 is changed, the voltage of the resistor R2 is changed. Synthetic capacity Ccd is changed in accordance with it and the frequency of an oscillator is changed. Thus, a trimmer capacitor is omitted by using the resistors R1 and R2 so that the occupying area of the circuit is reduced to be about 80% as compared with the conventional one. Sufficient size of frequency change width is selected by properly selecting the constant of the capacitors C4 and C5 by the change of the resistors R1 and R2. Thus, the number of times of frequency adjustment before fitting a case are reduced.
