摘要:
The present invention relates to a tool for analyzing by priority a defect having a high possibility of causing an electrical failure when inspecting a particle and a pattern defect in a piece of work which constitutes an electronic device such as a semiconductor integrated circuit, and relates to a system therefor. On the basis of the result of comparison between defect information which is the result of inspection by an inspection tool and layout data stored in an auxiliary storage device, or on the basis of the result of reinspection by comparison between a defect and a wiring pattern as a background by an inspection processing operation unit, an object to be reviewed is selected using review conditions stored in the auxiliary storage device.

A method for evaluating the period of beer foam stability of sample of equal foam layer thicknesses comprising the steps of obtaining a sample by pouring a fixed amount of prescribed beer into a standard glass from a pouring height calculated to approximate a standard preset thickness, measuring the foam layer thickness and the period of foam stability of the sample, comparing the measured values with the standard foam layer thickness value, adjusting the beer pouring height to approximate the standard foam thickness more closely, pouring the fixed amount of the prescribed beer into a standard glass to obtain another sample, and measuring and storing the foam thickness value and period of foam stability of the sample, and reading the period of foam stability value corresponding to the standard foam layer thickness from a graph obtained by plotting the foam layer thickness data against the period of foam stability data for a plurality of samples obtained by repeating the above steps a number of times.

A method that allows an individual to personally test for contaminants in an air supply. The method consists of purchasing the test kit, mounting the test kit to an existing particulate filter, placing the mounted test kit and particulate filter into the filter housing and blowing air through the test kit. The test kit is then removed from the furnace, repackaged and sent to a laboratory for analysis. The air quality test kit comprises a test filter, a filter backing pad, a support and a pair of end caps. The test filter, the filter backing pad and the support form a device to capture and retain particles carried in an airflow.

In a sampling inspection managing system, for each processing step, a setting is made on a processing flow table as to whether the processing step concerned is a step for determining the sampling inspection frequency of a specific inspection step. For a processing step which is set as “being a step for determining the sampling inspection frequency”, the inspection frequency of the specific inspection step is set on a sampling frequency setting table for every kind of product to be processed. Further, for the processing step, the processing number of lots is counted for every kind of product in a count table, and, on the basis of the processing number thus counted, a judgment is made as to whether each lot is a lot to be inspected in the specific inspection step. The judgment result is stored as information for the lot in a lot table. Accordingly, the inspection can be carried out at an inspection frequency suitable for every kind of product.

A method and apparatus for automating the qualification process for chromatographic systems. Automation technology and regression analysis are used for qualifying a chromatography system. The trained operator prepares the chromatography system to ensure that the samples, solvents, and the separation column are ready for analysis. The qualification of the detector, the solvent delivery system, the sample manager, the gradient proportioning system, the column heater, and the delay volume of the chromatography system are completed without the necessity of operator intervention. Regression analysis is performed to compute performance statistics that demonstrate the accuracy, linearity, and precision of the chromatographic system and quantify its suitability for chromatographic analysis.
摘要:
A method and system for monitoring a series of events performed in one or more applications on a computer. The recorded events enable users on the same or different machines to repeat the recorded events at a future time. The recorded events thus improve efficiency of an experienced user and/or demonstrate to a new user how more experienced users operate the application(s). The real-time sharing of recorded events allows multiple users to collaborate and “share” an application.

This invention provides a method for invisibly tagging, for subsequent identification purposes, various liquid petroleum hydrocarbons, such as crude oil, diesel fuel, heating oil, kerosene, lubricating oils, waxes, jet fuel, and in particular gasoline, remarkably using visible dyes by incorporating therein one or more visible dyes at minute levels such that they cannot be visually detected by the human eye. Visible dyes which have high solubility in petroleum hydrocarbons and maximum absorption in the 550-700 nm visible wavelength range are used to impart such invisible markings. The visible dyes, although employed at non-visible levels, are still capable of detection in a relatively quick and simple manner which requires minimal instrumentation, creates no waste products for disposal, and gives true quantitative results of dye concentrations in the field. This invention, therefore, further provides a method for so identifying the tagged petroleum hydrocarbons by exposing the tagged hydrocarbon to visible light having wavelengths in the portion of the spectrum utilized and detecting and quantifying the presence of the dyes in the tagged product from their characteristic absorption with available absorption detection equipment sensitive in this spectral region. This invention also provides visible dye compositions particularly appropriate for said invisible tagging.
摘要:
A system/method of establishing a two-way communication system between a testing/manufacturing site and a component vendor is disclosed. The system allows the test results related to a component failure to be immediately available to a vendor by allowing the vendor password protected access to a product database that contains information regarding the product being tested. The system automatically alerts the vendor associated with the defective component, and allows the vendor to download the vendor's failure analysis report to the product database as soon as it becomes available. Upon receipt of the vendor's failure analysis report, the appropriate testing/manufacturing personnel are notified.
