What is a piezoelectric device? What happens when pressure is applied? The piezoelectric effect is a phenomenon that occurs primarily in dielectric materials, such as quartz and tourmaline, wherein an electric charge is produced owing t[...] What is surface treatment? Explaining the main types and the role of power supply Surface treatment is an additional process applied to the surface of a material for the purpose of adding functions such as rust and wear resistance or improving the decora[...] Radiation Effects on the Human body and the safety of X-ray equipment Radiation is a general term for alpha, beta, and gamma rays generated by the decay of radioactive isotopes, cosmic rays from outer space, and particle rays and electromagne[...] What is the difference between Radioactivity, Radiation, and Radioactive Materials? Many of us have heard the words radioactivity, radiation, and X-rays before. Perhaps you may have a somewhat scary image of them. However, radioactivity and radiation are f[...] Constant Voltage (CV) vs Constant Current (CC) Power Supply, What is the difference? A power supply is a device that supplies electrical energy to one or more electric loads. They are primarily of two types: voltage sources and current sources. In general, [...] Difference between DC power and AC power There are two methods of electric current. These are direct current (DC) and alternating current (AC). Direct current is a method in which electricity always flows in a certai[...] Basics of Power Electronics that Support a Decarbonized Society Power electronics refers to technology that converts and controls electric power using semiconductor devices for electric power. Especially for a decarbonized society, it[...] For New Electronics Engineers, How to Use the Power Supply Safely Many new employees in Japan will join the company in April. Accidents and injuries caused by lack of knowledge and experience tend to occur during this period. This time, we wil[...] Electron Microscope and Analysis - Scanning Electron Microscope (SEM) Technical Explanation Series (3) - We will introduce a method to analyze what kind of elements are contained in a sample using a Scanning Electron Microscope (SEM) and an Electron Probe Micro Analyzer (EPMA[...] X-ray Image Processing and Automated Inspection - X-ray Non-Destructive Inspection series (3) - Non-destructive inspection using X-rays can perform various inspections. The most widely used is the inspection to detect foreign substances mixed in. Let's introduce t[...] Preceding 10 items 1 2 3 4 5 6 7 8 9 10 11 12 Next 10 items
