Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a constant photographic density of a film regardless of a type of an imaging device by making correcting parameters of an automatic control circuit interchangeable according to the imaging device selectively used. SOLUTION: When an X-ray emitted from an X-ray tube 3 permeates an object and enters into an X-ray/light converter 4a, it is converted into an optical signal, further converted into a current (i) by a light/current converter 4b and is fed to an integrator 4c. The integrator 4c is provided with correcting resistors corresponding to each imaging device 5, and its output Eo is corrected by a value proportional to the intensity of the phosphor of each imaging device 5, that is, the current (i). Thus, by setting the correcting resistance value according to each imaging device 5, the photographic density of a film can be adjusted to a constant even if the imaging device 5 is replaced with another one.  The output voltage Eo of the integrator 4c is compared with a reference voltage Es of a reference voltage generator 4d by the use of a comparator 4e and when it reaches the reference voltage Es, the X-ray is stopped by outputting an X-ray stopping signal from the comparator 4e.

Title: Front and back surface discrimination method and apparatus
Inventor: YASUOKA MASAZUMI
IPC: G01B7/00
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To discriminate the front and back surfaces of a semiconductor wafer which bas a thin film semiconductor is only on the front surface. SOLUTION: The thin film semiconductor 15 of high resistance growth has a photoelectric effect, so that electric resistance is changed by light irradiation. This phenomenon is different from the change of electric resistance of a semiconductor wafer 16. When the semiconductor wafer 16 is irradiated with an intermittent light and the electric resistance is measured, it changes remarkably by switching the light, in the case that the thin film semiconductor 15 formed. Thereby the front and back surface of the semiconductor wafer 16 can be discriminated.
