Impedance is a quantity that indicates "electrical resistance" in an electrical circuit. Unlike the resistance in direct current (DC) circuits, it serves as an important indicator of the relationship between voltage and current in alternating current (AC) circuits. Resistance has the characteristic of converting electrical energy into heat and indicates the ratio of voltage to current in DC circuits. On the other hand, impedance indicates the ratio of voltage to current in AC circuits and is a complex quantity that includes not only resistance but also reactance and inductance. ■ Measurement Methods and Precautions To measure impedance, specialized equipment such as an impedance analyzer or an LCR meter is used. By using these devices, you can accurately grasp the impedance characteristics and reactance components for each frequency. When measuring, it is important to be aware of the effects of parasitic inductance and capacitance. Especially at high frequencies, errors are likely to occur, so the arrangement of cables and shielding treatment becomes crucial. Additionally, if the calibration of the measuring instrument itself is insufficient, errors can be amplified, making regular adjustments and management essential for improving reliability.

A light sensor is a device that detects light and converts it into an electrical signal. The basic mechanism involves detecting incoming light and converting it into an electrical signal through various responses at a part called the "light-receiving element," depending on the intensity and wavelength of the light. The operating principle of a light sensor is to detect various information based on the magnitude of the current generated when light hits the light-receiving element. In the case of a photodiode being used as the light-receiving element, when light is incident, photons generate and separate electrons and holes within the semiconductor, producing a current in the external circuit. Since the current changes in proportion to the intensity of the light, it is possible to measure the strength of the light electrically. Light sensors are widely applied in various fields. Here are some specific examples: ● Industrial field: Quality control of products and position detection on automated lines ● Medical field: Pulse oximeters that measure oxygen concentration in the blood, imaging diagnostic devices that utilize light ● Daily life: Automatic doors, brightness adjustment of smartphone screens, automatic lighting of car headlights, etc. At Nippo, we also have a track record of developing light sensors for agricultural use that utilize photodiodes.

An LED is a semiconductor device that emits light when an electric current passes through it. Due to reasons such as low power consumption, long lifespan, and the absence of ultraviolet and infrared rays, lighting fixtures using LEDs have become widespread. An LED is formed by joining two types of semiconductors: "p-type semiconductor" and "n-type semiconductor." The p-type semiconductor has a high concentration of holes (positive charge carriers), while the n-type semiconductor has a high concentration of electrons (negative charge carriers). ■ Flow of the LED Light Emission Principle 1. Apply a forward voltage to the LED. 2. When voltage is applied, the "holes" in the LED move towards the "n-type semiconductor" side, and the "electrons" move towards the "p-type semiconductor" side. 3. At the junction of the p-type and n-type semiconductors, holes and electrons combine, generating light energy and causing the LED to emit light. Thus, the light emission of an LED is a mechanism where electrical energy is directly converted into light within the semiconductor. The color of the light emitted by an LED varies depending on the semiconductor materials that make up the LED. The wavelength of the light produced differs based on the compounds used in each semiconductor, allowing for the combination of compounds to express different colors.

Due to its simple structure, it is used in many places such as apartments, buildings, and factories. ■ Mechanism of Operation Inside the float, there is a magnet, and when the float approaches the reed switch, the contacts of the reed switch close, allowing the electrical circuit to conduct. Conversely, when the float moves away from the reed switch, the contacts of the reed switch open, cutting off the electrical circuit. By detecting the position of the float, which moves up and down according to the displacement of the liquid surface, the water level in the tank can be monitored. ■ Usage A stem (core rod) is fixed to the bottom or top of the tank, and it is connected to the electrical wires drawn from the reed switch. This electrical signal is used to control submersible pumps or valves. Recently, there are services that allow remote monitoring of the water level in tanks located in distant places via a web server, enabling users to understand the tank's condition from an office without having to visit the site. Our company applies the above technology and is engaged in development across various fields. Please feel free to contact us.

Currently, motors are widely used in precision equipment fields such as computers and HDDs. We will introduce the principles and examples of use of the technology called "PWM control," which is used for motor control. PWM is one method of controlling power using semiconductors. It is a type of pulse density modulation (PDM), and a PDM with a constant frequency is called PWM. PWM can be controlled by repeating the ON and OFF of a switch, and this high-speed switching generates a pulse waveform. By changing the duration of the pulses, it controls the power supplied to the load. PWM control has excellent controllability. For example, by controlling the rotation speed of a cooling fan motor, the speed can be adjusted in response to the temperature of the object being cooled, thereby controlling the cooling performance. (Without control, the rotation speed remains constant, which can lead to excessive cooling even at low loads.) Additionally, there is the advantage of increased quietness, as the minimum rotation speed is achieved at low loads, reducing the noise generated by the rotation. Our company applies various technologies and offers application development in a variety of fields. Please feel free to contact us.
