Title: Method and system for inspecting unevenness
Inventor: UEDA KUNIO
IPC: H01J9/42
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To determine the unevenness of gray pattern quantitatively by deter mining a blurred image of gray pattern and a power spectral distribution in a partial region thereof, adding the power spectrums in a specified spatial frequency region thereof and comparing the sum with a threshold value. SOLUTION: An image processor 54 executes a software through a CPU 66 to perform various operations. At first, a CCD camera 49 picks up the image of shadow mask SM of an object for which the unevenness is inspected at a position shorter by a specified length than the focal length thus inputting a blurred image. A plurality of square processing regions are then clipped from the image and two-dimensional Fourier transform is performed for each region thus calculating a power spectrum. Subsequently, the power spectrum values are added in a specified frequency region for each region to obtain a sum of power spectrums. Furthermore, a maximum sum is determined for each region and compared with a predetermined threshold thus deciding whether the mask SM is acceptable or not. According to the method, acceptability of the mask SM can be determined quantitatively.

Abstract: PURPOSE:To improve the capacity factor of a power supply voltage by varying an output current from zero linearly by acquiring the output current from the collection electrode of a transistor whose discharge electrode is coupled with a resistor and the inversion input terminals of plural operational amplifiers. CONSTITUTION:The discharge electrode of the transistor 10 is coupled with the resistor 12 and the inversion input terminal of the operational amplifier 14, and the control electrode of the transistor with the output terminal of the operational amplifier 14, and furthermore, a reference voltage source 16 is connected to between the non- inversion input terminal of the operational amplifier 14 and the other terminal of the resistor 12.
