IPC: G01T1/04
Filed: 1985-07-18
Abstract: PURPOSE:To measure a radiated dosage in a wide range highly accurately by changing the wavelength of light made incident upon a coloring material to measure the dosage. CONSTITUTION:Light 3 made incident upon a sample measuring part 4 is branched to transmitted light 3T and reflected light 3R by a half mirror 41. The transmitted light 3T is reflected by an optical path adjusting mirror 42 and then made incident upon one of colored glasses 44 set up on a sample cell holder 43. The transmitted light 3TT through the glass 44 is reflected by a mirror 45 and made incident upon a transmitted light measuring part 5.

In this case, gamma rays are not irradiated to the glass 47, which is used for a reference glass for measuring the transmitted light. The transmitted light 3RT through the glass 47 is made incident upon the measuring part 5. The measuring part 5 selects these 2 kinds of transmitted light 3TT, 3RT alternately to measure the quantity of light by the same photomultiplier. A wavelength selector 2 uses the measured data of the measuring part 5 to select the wavelength of the light 3 outputted from a light source 1.

IPC: H01L21/66
Filed: 1992-06-17
Abstract: PURPOSE:To measure a cubic positional relationship of void in a bump accurately by comparing two radioscopic images taken from a different direction. CONSTITUTION:An X-Y table 7 is moved at a constant speed in a direction X and intermittently in the direction Y while it returns. X rays transmitted through a circuit board 20 develops a fluorescent image glowing on the rear side of a fluorescent screen 8 and the intensity of emission at first and second measuring positions 11a and 11b is measured with line sensors 10a and 10b. An image memory 12 which is adapted to delay an output of the sensor 10a for observing the position 11a by specified time computes an stores a pixel to be measured during the period. An output of the memory 12 and an output of the sensor 11b are compared with a reference pattern by means of an image processor 13 to determine peak points of the respective void patterns. The peak positions are standardized depending on the size of a bump image to make a relative position of the void image. A difference of the relative position is determined with a comparator 14 as displacement. When the displacement exceeds a value preset, a signal is outputted at an output end to notify the abnormality of the shape of a bump.

IPC: G01C17/28
Filed: 1988-06-24
Abstract: PURPOSE:To enable temporary correction by calculating a vector directed to the center of a circle from an origin of coordinates which vector corresponds to a terrestrial magnetism direction signal, calculating the variation between the previous and present directions, and obtaining a value of coordinates of the center of said circle from a value of coordinates of the present terrestrial magnetism direction signal and said vector when said variation is over a predetermined reference. CONSTITUTION:A terrestrial magnetism sensor 2 has such construction, for example, that a ferromagnetic body is wound by a pair of coils orthogonal to each other. A terrestrial magnetism direction signal generated from the sensor 2 is composed of two orthogonal components Vx and Vy. An operating means 3 has a microprocessor as its central function. A vector directed to the center of a circle from an origin of coordinates and corresponding to the terrestrial magnetism direction signal is calculated and stored. Then, the variation between the previously-detected direction and the present detected direction is calculated. If the variation exceeds a predetermined reference, the value of coordinates of the present direction signal and the stored vector are employed to calculate the value of coordinates of the center of the circle. By using this value of coordinates of the center of the circle, the movement of the circle can be corrected on the whole.
