Title: Protective system of power converter for dc electric rolling stock
Inventor: YOSHIKAWA HARUKI
IPC: B60L3/04
Filed: 1986-10-29
Abstract: PURPOSE:To prevent the scale-up of a device by using a resistor for inhibiting rush currents at a time when charging a filter capacitor for suppressing short circuit currents. CONSTITUTION:An electromagnetic contactor 21 is closed while a GTO thyristor 23 for a short circuit being brought to an OFF state prior to operating a thyristor inverter 8, and charging currents are caused to flow through a filter capacitor 7 through a current limit resistor 22. When the filter capacitor 7 is charged completely, the GTO thyristor 23 for a short circuit is turned ON, and the thyristor inverter 8 is operated. When the accident of the short circuit of an arm is generated in the thyristor inverter 8 during working, an OFF command is transmitted over the GTO thyristor 23 for a short circuit and the electromagnetic contactor 21. Since the GTO thyristor 23 for a short circuit is brought quickly to the OFF state, the increase of short circuit currents is inhibited by the current limit resistor 22.

Title: Binary image reduction processing system
Inventor: HONMA NOBUTAKA
IPC: G06T3/40
Filed: 1987-10-13
Abstract: PURPOSE:To shorten processing time and to unify reduction patterns by obtaining a desired reduction pattern by operating the sum of products of wrighting patterns for a pattern whose center is the point in the nearest proximity to a corresponding binary image before reduction that corresponds to respective pixels of a binary image after reduction. CONSTITUTION:From an inputted binary image before reduction, a nearest proximity point processing part 1 finds the nearest proximity point corresponding to the respective pixels of a binary image after reduction. For the pattern whose center is the nearest proximity point, a multilevel reduction pattern generation part 2 generates a multilevel reduction pattern by summing the products of prescribed weighting patterns, and thereafter, said pattern is sliced in a prescribed binarization level by a binarization processing part 3, and thus a binary image reduced as desired is generated. By this generating a binary image reduced as considering the nearest proximity point corresponding to the respective pixels of a binary image after reduction as well as the information of the circumference of said point, the processing time can remarkably be shortened, additionally, reduced binary images can be unified.

Title: Manufacture of cesium separation material
Inventor: TANIHARA KOUICHI
IPC: B01J20/26
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to repeat the use of a cesium separation material comprising a composite formed of an insoluble hexacyanoferrate (II) of the copper salt family borne by a porous carrier. SOLUTION: A water-soluble hexacyanoferrate(II) or a hexacyanoferrate(III) is borne in the pores of a porous carrier, and then is treated with a solution obtained by solving a copper salt in a solvent in which the described salts are hardly soluble. In addition, an insoluble hexacyanoferrate(II) or a hexacyanoferrate(III) of the copper salt family is caused to sediment in the pores of the porous carrier. In the case of the hexacyanoferrate(III), it is further treated by a reduction process to convert to the insoluble hexacyanoferrate(II) of the copper salt family. Thus it is possible to manufacture the cesium separation material.

Filed: 1994-10-24
Abstract: PURPOSE: To prevent interruption by unrequired and unurgent telephone calls and to save communication time by performing an execution processing corresponding to the ID of a caller and using conditions when a call is terminated. CONSTITUTION: An automatic response part 1 automatically responds to calling from a line and a voice guidance transmission part 2 transmits a message for urging ID input to an opposite party automatically responded to in the automatically response part 1.

Abstract: PURPOSE:To realize high-speed random access by making access to data in such a way that digit and line address signals are implemented from an input address signal and the digit and line address signals are compared with the previous input signal and, when they coincide with each other, it is judged that the input is the first one. CONSTITUTION:An address implementing circuit 3 outputs a row address RA implemented from a supplied input address signal line 4 and a column address CA to another storage circuit 7 through another signal line 6. When an access- enable signal is supplied to a control circuit 1 from an external device, the comparator circuit 9 compares the previous row address RA and current row address RA whether they coincide with each other or not. When a coincidence signal is supplied, the control circuit 1 judges that the input is the first one and successively outputs an RAS selecting signal and CAS selecting signal to a selection circuit 11. The row address RA and column address CA from the selection circuit 11 are respectively stored in buffers 13 and 14. Access to data is performed to the line corresponding to the row address RA stored in the buffer 13 and to the position of a memory matrix 17 of the digit corresponding to the column address C.
