Title: Zirconium or zirconium-based alloy for nuclear fuel element sheathing pipe
Inventor: KUBO TOSHIO
IPC: C22C16/00
Filed: 1987-07-15
Abstract: PURPOSE:To increase the strength of Zr or a Zr alloy and to decrease the wall thickness of a sheathing pipe by dispersing fine ceramic particles having high hardness in the base phase of the Zr or Zr alloy at the time of producing a nuclear fuel element sheathing pipe with Zr or a Zr alloy. CONSTITUTION:Plural fuel elements 2 such as nuclear fuel pellets are enclosed in the sheathing pipe 1 having a Zr liner layer 1a and made of Zr or a Zr alloy, etc., (e.g., Zr-Sn alloy). In this case, the wall thickness of the sheathing pipe 1 is decreased to the utmost to improve the heat transfer efficiency from the nuclear fuel element 2 to cooling water, and further the fine particles 11 of a ceramic such as Al2O3, SiO2, and Al4C3 having the diameter D0 of 0.1-1.0mum are dispersed in the Zr or Zr alloy as the base phase 12 of the sheathing pipe so that the spacing l0 between the particles is controlled to 0.1-1.0mum to prevent the stress corrosion cracking. Consequently, the strength of the sheathing pipe 1 made of Zr or a Zr alloy is increased, and the wall thickness can be decreased.

Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a digital signal reproducing device which converges fast and surely reproduce recorded information of a recording medium. SOLUTION: An error computing element 16 selects an effective component of error information, and makes an internal digital low-pass filter integrate the component and outputs it as a DC drift component(DC offset component) only when 0-point information from a tapped delay circuit 14 is '1' (at this time, a timing is shown when a sampling point formed by re-sampling exists). The output of an error computing element 16, a DC offset output component, are inputted to a subtracter circuit 13, and subtracted from the output signal of an AGC(automatic gain control)-ATC(automatic threshold control) circuit 12. Thus, the DC component can be eliminated from the output of the AGC-ATC circuit 12 through the subtracter circuit 13.
