Title: Method for recovering nitric acid from nitrate
Inventor: HAMANO TOSHIKATSU
IPC: B01D61/44
Filed: 1990-08-07
Abstract: PURPOSE:To improve current efficiency in recovering nitric acid by electrodialyzing an aqueous solution of a nitrate using a specific electrodialyzer.

Title: Image signal processor
Inventor: SAKURAI MASARU
IPC: H04N19/00
Filed: 1993-08-23
Abstract: PURPOSE:To prevent image failure from being generated at a band compression processor even when an image three-dimensionally containing much high frequency components is inputted by switching and selecting either the direct image signal of an input terminal or the output image signal of a three- dimensional filter means corresponding to the accumulated value of high frequency components provided from a high frequency component extracting means. CONSTITUTION:An accumulator 18 takes the absolute value of the high frequency component of a signal extracted by a three-dimensional filter 12 and accumulates it for certain time set in advance. The output of this accumulator 18 is supplied to a deciding circuit 19 and when the accumulated value exceeds a certain threshold value, a switch 17 is controlled. Normally, the switch 17 selects the output of a delay circuit 15 to which an input image signal is directly inputted but when the deciding circuit 19 decides that the accumulated value exceeds a certain threshold value, the switch selects the output of a delay circuit 16 to which the output of the three-dimensional filter 12 is inputted. Therefore, when the degree of redundance of the input image signal is a little, the input image is supplied while being limited within the range of ability of a band compression processor 20.

Title: Rotor for superconducting electrical rotary machine
Inventor: HIRAO TOSHIKI
IPC: H02K55/04
Filed: 1987-08-21
Abstract: PURPOSE:To improve not only the shielding effect but also the reliability and profitability of an apparatus by providing low temperature dampers composed of superconductors on the outer surface of a refrigerant container. CONSTITUTION:Low temperature dampers 51 of a rotor for a superconducting electrical rotating machine are obtained by fixing of superconductors 51a in grooves of the surface of a refrigerant container 6. Said superconductors 51a are arranged axially and circumferentially to form a so-called cage electric circuit. Then, if a variable magnetic field is applied to said low temperature dampers 51, such current as cancelling said variable magnetic field flows through the superconductor 51a. In this case, as the electric resistance of the superconductor 51a is zero, there is nothing obstructing the flow of a current and a large shielding effect is exhibited. Also, no joule loss is generated either. Further, the refrigerant container 6 is obtained by fitting of a high strength non-magnetic metal cylinder to a coil mounting shaft 2 to show a large rigidity integrally with said coil mounting shaft 2.
