EVALUATION APPARATUS AND EVALUATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18582450 titled 'EVALUATION APPARATUS AND EVALUATION METHOD

The evaluation apparatus described in the abstract includes an evaluator with a transparent column for storing a liquid containing defects, an irradiator for irradiating the liquid, an imager for capturing scattered light from the defects, and a determiner for analyzing the defects.

• The apparatus can detect defects in a liquid containing bubbles, metal particles, and other particles.
• It calculates the particle size and refractive index of the defects.
• The apparatus filters the liquid before evaluation.
• It can determine the presence of bubbles, metal particles, or other particles in the defects.
• The apparatus connects to a filter via a pipe for liquid filtration.

Potential Applications: - Quality control in manufacturing processes - Research and development in materials science - Environmental monitoring for pollutant detection

Problems Solved: - Efficient and accurate defect detection in liquids - Real-time analysis of particle size and composition - Streamlined evaluation process for industrial applications

Benefits: - Improved product quality - Cost-effective defect detection - Enhanced research capabilities in materials science

Commercial Applications: Title: Liquid Defect Evaluation Apparatus for Quality Control in Manufacturing This technology can be used in industries such as pharmaceuticals, semiconductor manufacturing, and food processing for quality control and process optimization.

Questions about Liquid Defect Evaluation Apparatus: 1. How does the apparatus differentiate between different types of particles in the defects? The apparatus uses imaging and analysis techniques to determine the composition of the defects accurately.

2. What is the significance of calculating the diffusion coefficient of the defects? The diffusion coefficient helps in understanding the behavior and characteristics of the defects in the liquid, aiding in quality control and research applications.

Original Abstract Submitted

An evaluation apparatus according to an embodiment includes an evaluator including a column being capable of storing a liquid containing defects, the column being transparent, the defects containing a bubble, a first particle containing metal, and a second particle being different from the bubble and the first particle, an irradiator irradiating the liquid in the column with an irradiation light, an imager imaging a scattered light emitted from the defects by the irradiation light, an analyzer obtaining a diffusion coefficient of the defects from the imaged scattered light, a calculator calculating a particle size and a refractive index of the defects, a determiner determining whether the defects contain the bubble or the second particle, or the first particle; a filter filtering the liquid, the filter including an inlet and an outlet; a first pipe connecting the outlet of the filter and the evaluator.
