Hinode electrical components are linear devices based on metal induction. The function of a sensor is to convert various measured physical quantities into electrical signals. In production processes, displacement measurement is generally divided into two types: measuring physical dimensions and measuring mechanical displacement. Depending on the form of transformation of the measured variable, displacement sensors can be divided into analog and digital types. Analog types can be further divided into property-based and structural types. Commonly used displacement sensors are mostly analog structural types, including potentiometric displacement sensors, inductive displacement sensors, synchros, capacitive displacement sensors, eddy current displacement sensors, and Hall effect displacement sensors. An important advantage of digital displacement sensors is that they facilitate direct input of signals into computer systems. Displacement is a quantity related to the movement of an object's position during motion, and the scope of displacement measurement methods is quite extensive. Small displacements are typically detected using strain gauge, inductive, differential transformer, eddy current, and Hall sensors. Large displacements are commonly measured using sensing technologies such as inductosyns, gratings, capacitive grids, and magnetic grids. Among these, grating sensors are increasingly widely used in industries such as machine tool processing and testing instruments due to advantages such as ease of digitization, high precision (with current highest resolution reaching the nanometer level), strong anti-interference capability, absence of human reading errors, convenient installation, and reliable use.

Hinode electrical component functions

(1) often compares sensor functions to the 5 major human sensory organs: photosensitive sensors for vision, acoustic sensors for hearing, gas-sensitive sensors for smell, chemical sensors for taste, and pressure-, temperature-, and fluid-sensitive sensors for touch. (2) Classification of sensitive elements: Physical category, based on physical effects such as force, heat, light, electricity, magnetism, and sound. Chemical category, based on the principles of chemical reactions. Biological category, based on molecular recognition functions such as enzymes, antibodies, and hormones. Typically, they can be divided into ten major categories based on their basic sensing functions: thermosensitive elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magneto-sensitive elements, humidity-sensitive elements, acoustic-sensitive elements, radiation-sensitive elements, color-sensitive elements, and taste-sensitive elements (some have also classified sensitive elements into 50 categories).

Hinode electrical component principles

A Schottky diode is a metal-semiconductor device made by using a noble metal (gold, silver, aluminum, platinum, etc.) A as the anode and an N-type semiconductor B as the cathode, utilizing the rectifying characteristics of the barrier formed at their contact surface. Because there are a large number of electrons in the N-type semiconductor and only a very small number of free electrons in the noble metal, electrons diffuse from the high-concentration B to the low-concentration A. Clearly, there are no holes in the metal A, so there is no diffusion movement of holes from A to B. As electrons continuously diffuse from B to A, the electron concentration on the surface of B gradually decreases, disrupting surface electrical neutrality and forming a barrier whose electric field direction is B → A. However, under the influence of this electric field, electrons in A also undergo drift movement from A → B, thereby weakening the electric field formed by the diffusion movement. When a space charge region of a certain width is established, the electron drift movement caused by the electric field and the electron diffusion movement caused by the concentration difference reach a relative balance, forming the Schottky barrier. The internal circuit structure of a typical Schottky rectifier uses an N-type semiconductor as the substrate, on which an N-epitaxial layer doped with arsenic is formed. The anode uses materials such as molybdenum or aluminum to create a barrier layer. Silicon dioxide is used to eliminate the electric field in the edge region, increasing the voltage withstand value of the tube. The N-type substrate has a very small on-state resistance, and its doping concentration is 110% times higher than that of the H-layer. An N+ cathode layer is formed beneath the substrate to reduce the contact resistance of the cathode. By adjusting structural parameters, a Schottky barrier is formed between the N-type substrate and the anode metal.

Hinode electrical component advantages

Components do not get consumed; no matter how excellent a vacuum tube is, it will gradually deteriorate due to changes in cathode atoms and chronic air leakage. For technical reasons, transistors faced the same problem at the beginning of their manufacture. They consume very little electrical energy, only one-tenth to one-hundredth of that of vacuum tubes. Unlike vacuum tubes, they do not require heating filaments to generate free electrons. A transistor radio can operate for six months to a year on just a few dry cells, which is difficult to achieve with vacuum tube radios. No preheating is required; they work immediately upon startup. For example, a transistor radio produces sound immediately when turned on, and a transistor television displays images quickly when turned on. Vacuum tube equipment cannot achieve this. After turning on a vacuum tube device, one must wait a while before hearing sound or seeing images. Clearly, transistors have significant advantages in military, measurement, and recording applications. They are robust and reliable, resistant to shock and vibration, which vacuum tubes cannot match. Additionally, the volume of a transistor is only one-tenth to one-hundredth that of a vacuum tube, and it generates very little heat, making it suitable for designing small, complex, and reliable circuits. Although the manufacturing process of transistors is precise, the steps are simple, which helps increase the installation density of components.
