Title: Analysis of total cerium ion content
Inventor: TAKADA YOSHITADA
IPC: C01F17/00
Filed: 1988-02-08
Abstract: PURPOSE:To simplify a total analysis of cerium ions, by converting cerium in a sample into trivalence to separate before the sample reaches a separation column after injected into a device. CONSTITUTION:Tetravalent cerium ions contained in a sample, whose main components in an eluate 1 are injected at a sample injection port 3 of a liquid chromatography, are reduced to trivalence and then, the sample is introduced into a separation column 6. Then, with the column 6, the cerium ions are separat ed form other trivalent rare earth metal ions in the form of trivalent cerium ions and cerium ions are totally analyzed via a detector 7. Here, since relatively stable components chemically are slow in reaction at a room temperature, they are heated with a heater 5 to be converted into trivalence when the sample is mixed into an eluate 1 before being introduced to the column 6. This enables an analysis on the total amont of cerium ions without a pretreatment intended to unify the valence of cerium ions in a sample solution to trivalence prior to the injection of the sample into the device.

Title: Suppressing method for input rush current
Inventor: SAITOU RIYOUJI
IPC: H02M1/16
Filed: 1981-02-25
Abstract: PURPOSE:To suppress the peak value of a rush current to a vaelue lower than the set value by interrupting a semiconductor element with the first set current value and conducting the element with the second set current value. CONSTITUTION:Even if a power source voltage is inputted, a semiconductor switching element 5 is first interrupted OFF, a DC current flows through a current limiting resistor R0, but the element 5 is immediately conducted, and a current flowed through the element 5. When the detected value reaches a set current value V1 by a current detector R1, the element 5 is interrupted by a controlling circuit CL. When the current is then reduced and the detected value is lowered to a set current value V2, the element 5 is conducted, and the current is again increased. Thereafter, this state is repeated to increase the charging voltage of the capacitor C. In this manner, the overcurrent at the starting time and instantaneously resetting time can be prevented.

Filed: 1984-02-14
Abstract: PURPOSE:To improve the out of roundness by generating the magnetic lines of force in the radial direction from the axis center of a workpiece installed into a container by a magnetic-field generator and generating the relative turn of working liquid for the workpiece by a relative turning means, thus allowing the relative turning collision of grinding grains onto the surface of the workpiece. CONSTITUTION:When an electromagnetic coil 38 is put into electric conduction, a magnetic field whose magnetic lines of force are directed in the direction of arrow (a) is generated, and then an electric motor 50 is put into electric conduction, and then magnets 58 and 42 synchronously revolve, and the magnetic fluid is turned by the rotary magnetic field, and a turning flow is generated in the direction of arrow (b) around a workpiece 70. Therefore, the magnetic fluid is applied with an attraction force in the direction of arrow (a) and a turning moment in the direction of arrow (b) and shifts towards the center at the speed in the vector sum of each speed in the both directions, and also grinding grains shift and uniformly collide onto the outer periphery of the workpiece, and surface polishing is performed, and the out of roundness is improved. Since the grinding grains are turned and the magnetic fluid is attracted onto the workpiece by the magnetic lines of force in the radial direction from the axis center of the workpiece, the vertical force component of the collision force of the grinding grains increases, the the collision effect is increased.

Abstract: PURPOSE:To prevent the occurrence of jam without the inferior control even when some irregular value is generated, by providing sensors on the terminal end of a paper feed path and the initial and terminal ends of a carrying path, and rememorizing the last measured value instead of the irregular value when a measured value on the paper feed path is out of a proper range. CONSTITUTION:Time TM1 from the restarting time of a feed motor 4 to the reaching time of a copying paper at a sensor 15 in front of a regist is measured and memorized, and the restarting time of the third paper feeding is set at the time when it is Td later than S,OPC instead of Tb when a linear velocity B of a glip roller 5 is constant. Said Td is expressed by Td= TR-[TM1+(l5+lB)/B], where TR is the time from detection of the S,OPC signal to start of regist motor 11, l5 is the distance from a sensor 16 to a regist roller 10, and lB is the required paper deflection amount in front of the regist. Now, when a difference between time TFn from a sensor 14 to the sensor 15 and the last data TF(n-1) is more than a fixed value, TF(n-1) is adopted instead of TFn, so that the inferior control at the time of generation of an irregular value can be prevented.
