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) and 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 Automatic 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[...] Electron Microscope Lenses -Electron Microscope (SEM) Technical Explanation Series (2) - This time, we will introduce the lens of the electron microscope in detail. The following figure shows the structure of the electron microscope introduced last time. Fi[...] How to View X-ray CT Images - X-ray Non-Destructive Inspection series (2) - Last time, we explained how X-ray CT works. This time, let's introduce how to save the captured data and how to utilize the data. The result of X-ray CT is basically sav[...] Basics of units and prefixes used in electronics When writing specifications, you will often write numerical values in various units. However, if the number has a large number of digits, it will be difficult to read if[...] Preceding 10 items 1 2 3 4 5 6 7 8 9 10 11 Next 10 items
