Title: X-ray analyzer
Inventor: FUNABASHI MANABU
IPC: G01N23/22
Filed: 1990-09-21
Abstract: PURPOSE:To cut high-order X rays and to shorten the measuring time by providing a total reflecting mirror on the light path of the X rays, relatively moving a linear reflecting mirror, a spectroscopic crystal and the like, and changing the incident angle of the X rays on the total reflecting mirror. CONSTITUTION:X rays B are emitted from an X-ray tube 10 on a total reflecting mirror 13 at a relatively large incident angle phi. Then, only the X rays having the wavelength that is about 2/3 time or more of the wavelength of the first-order reflected X rays B1 which are required for analyzing a sample W are totally reflected from the mirror 13. The reflected X rays BO are incident on a spectroscopic crystal 11 at an incident angle theta. Then a pulse motor M1 is rotated, and a link L1 is turned. Thus, the incident angle phi is gradually reduced. At the same time, pulse motors M2 and M3 are rotated by the same angle, and sliders S1 and S2 are moved on links L4 and L5 by the same amount. Thus, the incident angle theta is gradually reduced. With the angles phi and theta being gradually changed, the intensities Io and I of the X ray B1 and the X ray B2 are measured with measuring devices 21 and 22, and the linear absorption coefficient is operated. The sample W is analyzed based on the change in obtained linear absorption coefficient.

Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To shorten cycle time by executing the arithmetic operation of division on first and second operands and a residual quotient signal and deciding a residual quotient based on the operation result. SOLUTION: In an operand selection block 18, the first and second operands op-a and op-b are processed and the operands op-a and op-b are sent to an addition block 20 with the residual quotient r-q generated in a different block. The addition block 20 executes the arithmetic operation of division. The operation result of the addition block 29 is sent to a register 120 and it is sent from here to a residual quotient decision block 22 through total lines sum 1, sum 2 and sum 3. The residual quotient block 22 decides the residual quotient based on an arbitrary total result from the total lines sum 1, sum 2 and sum 3. Thus, the half of cycle time can be allocated to addition logic and the remaining half to the other logic. Then, cycle time can be shortened.
