Abstract: PURPOSE:To make it possible to conduct stable analysis without necessitating reclamation with interruption of analysis by making the eluent from the partition wall of an ion exchange membrane of a double walled tube of a certain length that comprises one cation exchange membrane tube and a particular reclaimed strong acid flow respectively in mutually opposite directions. CONSTITUTION:In an ion chromatography of anion, an eluent liquid that contains a constituent that is separated and eluted from the column is led into the cation exchange membrane tube 71 from its opening 75a to its outlet 75b, and then it is sent to an electric conductivity meter. On the other hand a reclamation liquid that contains a strong acid of high degree of dissoclation and large resistance to anion of H<+> is made to flow between an outer mantle tube 72 of Teflon or other material and a tube 71 in the direction opposite to the eluent liquid from the inlet 76b to the outlet 76a to exchange Na ion in the solution for H<+>, which keeps low the base line in the electricity conductivity meter.

Abstract: PURPOSE:To perform high-precision axis alignment at a connection place (position) by irradiating the connection point of optical fibers with ultraviolet rays and allowing cores to emit light, and monitoring the cores themselves by said visible light simultaneously in orthogonal directions. CONSTITUTION:Optical fibers 33 and 34 to be connected are butted against each other in a direction X and their connection point is irradiated with ultraviolet convergent rays 32 from an ultraviolet-ray source 31.

Title: X-ray mask and manufacture thereof
Inventor: OIIZUMI HIROAKI
IPC: G03F1/22
Filed: 1990-07-13
Abstract: PURPOSE:To suppress a positional distortion caused by the deterioration of a material due to an X-ray exposure and to hold the array of mask patterns accurately by reducing an impurity quantity contained in a mask base material. CONSTITUTION:An oxygen amount in a silicon mask base material is controlled. That is, oxygen contained is an impurity in a silicon nitride film 2 forms a chemical bond with silicon in the film. Since the Si-O bond is collapsed upon reception of an emitted radioactive ray and a positional distortion is generated by the deterioration of the material, an impurity oxygen quantity in the film 2 is reduced to a predetermined value or less. Thus, an X-ray mask of high quality in which the positional distortion caused by the deterioration of the material due to the X-ray exposure does not occur due to the influence of the collapse of the Si-O bond, is obtained.

IPC: G01S13/24
Filed: 1980-12-25
Abstract: PURPOSE:To realize a frequency agility radar small in the pulse width by constructing an AFC circuit with the combination of a closed loop system and an open loop system. CONSTITUTION:A sample hold circuit 10 acts as AFC of a closed loop system as a switch 16 opens immediately before the circuit is closed starting from the presetting of a voltage control oscillator VCO6. Then, upon the closing of the sample hold circuit 15, the switch 16 is closed and the output voltage of a discriminator 8 is amplified with an amplifier 14 to be an input voltage of the oscillator VCO6. Since this voltage is in the linear area of the discriminator 8, the action of the open loop system serves to improve the accuracy of the control in the closed loop. Thus, this AFC circuit can improve the accuracy of the frequency control in a frequency agility radar small in the pulse width.

Title: Backlash correction system
Inventor: HORIKAWA FUMIHIRO
IPC: G05D3/12
Filed: 1995-06-27
Abstract: PURPOSE: To reduce an error owing a backlash by setting a response waveform for backlash correction to a proper waveform. CONSTITUTION: A motor reversing detection part 8 judges the reversing of a motor from a position command and the speed command of a position control part 2. A backlash position correction part 9 receives the judgement of the motor reversing detection part 8 and adds a previously set backlash position correction quantity to the position command to correct a position error corresponding to a backlash. Further a backlash speed inverse transmission correction part 10 uses the inverse transfer function of a speed loop for the output of the backlash position correction part 9 for processing and adds the processing result to the speed command on a feedforward basis. Consequently, the influence of the transfer function of the speed loop is eliminated, the waveform of a response can be converted into a proper response waveform, and optimum backlash correction is possible.
