Abstract: PURPOSE:To generate no radioactive waste as a separated body and to obtain a superb nuclear characteristic in a neutron economy by sticking burnable poison elements such as a B, a Gd, a Cd, a Dy and so on, to a guide tube of a control rod constituting a fuel assembly. CONSTITUTION:As elements of burnable poison 2, elements having large neutron absorption cross-section such as a gadolinium (Gd), a cadomium (Cd), a dysprosium (Dy), a samarium (Sm), a silver (Ag), an indium (In) and so on, other than a boron (B), are used. These poisons 2 are stuck to a control rod guide tube 1. As an actual method, in case that the poisons 2 are used in a form of a metal, a method of making the guide tube of a double tube with the poisons 2 and of rolling together, is adopted. As an another method, a plating, a vapor deposition or a sputtering method can be used. In the case that the poisons 2 are oxides, the poisons are stuck by a sintering, a sputtering method or by other similar method.

Abstract: PURPOSE: To obtain a rotary two-dimensional pattern at a high speed by reading a stored original two-dimensional pattern by scanning at a fixed angle in a horizontal direction and then by scanning at a fixed angle in a vertical direction, reading and storing it.  
     CONSTITUTION: Scan addresses of memory 100 where an original two-dimensional pattern is written are set to row and column address counters 110 and 130. Dividing ratios of row and column divider circuits 120 and 140 are set to (m) and one respectively and while counters 110 and 130 are brought under control, memory 100 is scanned and read horizontally along slanting scanning lines according to the dividing ratio to write data in memory 200. Data are written in memory 200 along horizontal scanning lines by row and column divider circuits 220 and 240. Next, dividing ratios of circuits 220 and 240 are set to one and (m) from memory 200 to read a conversion two-dimensional pattern along slanting scanning lines in the vertical direction and they are written in pattern memory 300 along vertical scanning lines.

Filed: 1991-01-14
Abstract: PURPOSE: To guide an electron beam of high quality in a gyrotron by arranging a cooled absorber in the proximity of the front of a quasi-optical element, and by absorbing at least one of strong secondary peaks caused by diffraction. CONSTITUTION: A quasi-optical structure includes a quasi-optical mirror 18a as a quasi-optical element, and a hollow cylindrical vessel 17 as an absorber.

The mirror 18a has a diameter D smaller than 50 times the wavelength of microwave, and a cross-sectional size of the mirror 18a is relatively made smaller. Thus, the microwave is entirely diffraced in a mirror 16a. The absorbing vessel 17 is carried as close to the mirror 18a as possible so that a secondary peak 20 is absorbed. Moreover, the cooled absorbing vessel 17 is provided to absorb at least one of maximum peaks of the strong secondary peak 20 caused by the cross-sectional size diffraction.
