Since the inside shaft 13 intersects right and left front angles...

PURPOSE:To enable mass-production industrially by refraining from applying heat treatment affecting superconductivity of compound superconductive material filled at time of filling process during or after cross-section reduction processing. CONSTITUTION:The process consists of a filling process to fill pulverulent or fibrous compound superconductive material 3 displaying superconductivity into a m...

Apparatus for forming an electron beam sheet includes a cathode member 5 having a slot 6 in a front surface thereof, a grid electrode 4 and the anode 1 of a thyratron. When it is desired to trigger the thyratron into conduction, a suitably large potential difference is applied between the cathode member 5 and the grid 4, resulting in a electron beam sheet being produced extensive of a slot 6 forme...

A discharge tube, for example, a thyratron, in accordance with the invention is generally cylindrical in structure having a first electrode (5) arranged co-axially about a second electrode (6). Thus in a thyratron the anode may surround the cathode or vice versa. The envelope may be tubular having an aperture at its centre. In another aspect of the invention, a discharge tube arrangement including...

The process makes use of biological nitrification in which ammonium is oxidised to nitrate in a reactor system (3, 9) with the aid of a biocatalyst (4, 12, 19) with immobilised cells which are entrapped in a gel or polymer. Preferably used are defined high-efficiency mixed cultures of nitrifiers (Nitrosomonas, Nitrobacter etc.). To achieve a high rate of breakdown, oxygen and carbonate or CO2 must...

PURPOSE:To raise processing efficiency of a vector instruction, and to execute an operation at a high speed, by comparing upper bits of each operand address of the previous and following instructions, and controlling a start to parallel processing to the following instruction in accordance with its result. CONSTITUTION:A coinciding circuit 1 compares vector length (OLD.VL) of the previous instruct...

PURPOSE:To decrease the issuing frequency of transfer commands by operating successively plural index registers while switching said registers and equalizing the number of commands between the reception side and the transmission side. CONSTITUTION:Plural index registers RI1-In are provided to a register file 1 and the contents of the index register designated by a counter a2 are outputted to an ad...

This invention relates to a deactivatable tag useable with an electronic article surveillance system and comprised of planar conductive material cut into a pair of inverse, first and second spiral conductors wrapped about each other and positioned for capacitive and inductive coupling. The invention also relates to method of making tags wherein conductors are cut from a planar web of conductive ma...

PURPOSE:To decide an irradiation field enclosed with straight lines in the directions of an X-axis and a Y-axis, by setting the X-axis and the Y-axis along two adjacent sides of the contour of a rectangular irradiation field on a recording medium, adding and tabulating picture data in the directions of the X-axis and the Y-axis, and comparing them with a prescribed threshold value. CONSTITUTION:Wh...

A coherent frequency, velocity responsive electronic surveillance system detects the motion of a transponder relative to two receiving antennas on opposite ends of a surveillance zone positioned at the exit of a retail store. Motion in opposite directions relative to the two antennas indicates that the transponder is within the surveillance zone. As a means of reducing false alarms, motion of a tr...

A process for treating organically contaminated liquid hazardous waste comprises adding to the waste Portland cement, fly ash and activated carbon.

A solid phase can be coated superficially with a polymeric coating by substituting immobilized metal ions on the surface of the solid phase with a hydrophilic polymer or a derivative or aggregate thereof, through a chemisorption process. The solid phase may comprise a magnetic material, such as magnetite, and may have a particle form. The coating can be produced by bringing the solid phase into co...

PURPOSE:To update a program without interrupting a system even in online repairing, by checking whether program update is enabled or not by a control-number counter. CONSTITUTION:A control table 13 in which programs controlled by a system and address information on the programs are registered is provided, and while a logical storage space 12 is divided into several fixed areas, control-number coun...
