Title: Method and device for defect judgement
Inventor: TAKAHASHI YOSHIHARU
IPC: G06T7/00
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of defect judgement by correctly evaluating defects which have small areas and are heavy like worm-eaten spots. SOLUTION: A judging part 8 calculates an average luminance H of pixels constituting the image of an object S to be judged and multiplies coefficients p1 to p3 and the average luminance H respectively to generate first to third luminance thresholds. The judging part 8 compares the luminance of each of pixels constituting the image of the object S to be judged with first to third luminance thresholds to calculate total numbers A1 to A3 of pixels whose luminances are lower than luminance thresholds respectively. The judging part 8 substitutes total numbers A1 to A3 of pixels into a formula K=α1.A1+α2.A2+α3.A3, where α1, α2, and α3 are weights, to obtain an evaluation value K, and a defect class corresponding to the evaluation value level, to which the evaluation value K belongs, is determined as the defect class of the object S to be judged.

Title: Epitaxial vapor phase growth device
Inventor: ROKUSHA TOSHINORI
IPC: H01L21/205
Filed: 1989-02-03
Abstract: PURPOSE:To obtain an epitaxial layer having uniform film-thickness distribution by controlling the spraying of a reaction gas and conducting epitaxial growth. CONSTITUTION:A gas introducing pipe is formed in double pipe structure composed of an inner pipe 9 and an outer pipe 10, and gas flow controllers are installed to the inner pipe 9 and the outer pipe 10 respectively. A reaction gas is sprayed from either of the inner pipe 9 or the outer pipe 10, and the spraying is changed over from the inner pipe 9 to the outer pipe 10 or from the outer pipe 10 to the inner pipe 9 on its midway of the spraying. When the spraying of the reaction gas is started from the inner pipe 9, an epitaxial layer 8 is formed in a projecting shape because the flow of the reaction gas blown off from the inner pipe 9 is thinned. When the layer 8 is formed in the projecting shape, spraying from the inner pipe 9 is stopped or a flow rate is reduced and the reaction gas is sprayed from the outer pipe 10 for a proper time at a proper flow rate in response to the conditions of the growth of the film thickness of the layer. Since the flow of the reaction gas from the outer pipe 10 is thickened, the growth of the periphery of a substrate 3 is increased, thus equalizing the film thickness of the epitaxial layer 8.

IPC: G06F3/06
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To guarantee a sure process for an input/output request by predicting the execution time of the input/output request at an input/output execution prediction request from external equipment. SOLUTION: When an input/output command is inputted from external equipment to an HDD(hard disk drive) control circuit 9 through an interface circuit 2, the HDD control circuit 9 decides whether or not the inputted input/output command is a command for execution time prediction. When the inputted input/ output command is the command (execution time prediction command) for execution time prediction, the execution time of the input/output command is predicted according to parameters of input/output operation passed as command parameters and the internal state of the HDD. Then the predicted execution time is compared with a closing time as the maximum permissible time of the execution time which is passed as a command parameter. Then when the execution time is within the closing time, data input and output are performed. Consequently, the throughput is improved.
