摘要:
A factor estimating support device supports estimation of factor from a result generated in a production system. In the factor estimating support device, material/environment history data and test history data acquired from the production system, and the causality structure data indicating causality between the plurality of variables are stored in the storage unit, where when determined that the final quality characteristic is abnormal in the final quality abnormal detecting part, determination is made on whether each variable other than the final quality characteristic is abnormal in the variable abnormality detecting part, and the determination result is reflected on a visible image in which the causality structure data is visualized in the visible image creating part.
摘要:
An inspection apparatus includes a discrimination function determination unit which determines whether or not a discrimination function forms an area including a discrimination sample. The discrimination function is used in non-parametric one-class discrimination. The discrimination sample is discriminated into a class as a single area in an input space where learning samples are plotted.

An information processing device stores an extracted feature of each inspection item of the process inspection, and a determination result of a final inspection in a memory device, calculates a separation degree between a distribution of features of products which were determined as good products at the final inspection and a distribution of features of products which were determined as defective products at the final inspection for every inspection item or every combination of inspection items based on data of the products stored in the memory device, selects an inspection item whose inspection standard is to be reset from the inspection items or the combinations of the inspection items based on a value of the separation degree. Thus providing a method of appropriately setting an inspection standard for detecting a defect sign during process inspection. Further a process inspection device and inspection standard setting device which implements the same.

摘要:
An inspection method and an inspection apparatus are disclosed, wherein the appropriate inspection can be conducted in accordance with the situation change of a nonconforming product from an initial stage, an adjust stage and a stable stage. The conformity/nonconformity is discriminated according to a MTS model and a one class SVM model based on the normal data obtained from a conforming product. The conformity/nonconformity is discriminated by both the MTS and the one class SVM in an adjust stage where a sufficient amount of sample data cannot be acquired or the shape of the conforming product distribution in the feature space and the shape of the normal area are unstable, and only by the MTS in a stable stage where a sufficient amount of sample data can be acquired and the shape of the conforming product distribution and the shape of the normal area are stable.

A Zn-Ni alloy having a high Ni content is used for supplying Ni.sup.2+ and Zn.sup.2+ ions into an acidic plating bath and for supplying Ni and Zn into a hot dip galvanizing bath. This alloy is characterized by being produced by using a flux consisting of a fused-salt former, which forms a salt having a melting temperature of 700.degree. C. or less, and Na.sub.2 B.sub.4 O.sub.7 and occasionaly additionally Na.sub.2 CO.sub.3. By using the inventive alloy, the bath can be quickly prepared, and Zn and Ni can be supplied to the bath without leaving the undissolved residue.

摘要:
A jet pump system for a water jet propelled boat is disclosed that provides for the adjustment of the area of the water intake opening or the water entry angle as a function of the speed of the boat. During low speed operation, the water inlet opening is adjusted to a maximum area, or the water entry angle is adjusted to a maximum angle to enable sufficient water to enter the water duct and permit efficient impeller operation. As the boat speed increases beyond a predetermined speed, the water inlet area is reduced, or the water inlet angle is reduced to prevent excess water from entering the water duct, thereby reducing the drag on the boat.
