[Information] Basic Knowledge of Connectors Release Announcement

Why does it get hot? An introduction to the mechanism of heat generation when electricity flows and the temperature of connectors.

This document explains connectors and heat generation. It covers the mechanism of heat generation when electricity flows, as well as the temperature of connectors and their rated current. We hope that people with detailed knowledge, as well as those who are not usually involved with connectors, can enjoy learning about them. 【Contents (excerpt)】 ■1. The mechanism of heat generation when electricity flows 　・Column 1: Heating of electric heaters and air conditioners 　・Column 2: Superconductivity ■2. Temperature of connectors (heat generation and dissipation) ■3. Rated current *For more details, please refer to the PDF document or feel free to contact us.

What types of connections are there? We will introduce basic knowledge such as troublesome rules regarding wire sizes.

This document explains connectors and wires. It includes how to connect connectors and wires, representative connection methods and their features, as well as solder connections, crimp connections, and more. It also introduces troublesome rules regarding wire sizes and the negative effects of pulling wires. 【Contents (Excerpt)】 ■1. How to connect connectors and wires - Representative connection methods and features of wires and connectors ■2. Solder connections ■3. Crimp connections ■4. ODU's crimping *For more details, please refer to the PDF document or feel free to contact us.

How does electricity transmit? Introducing the mechanism and variations of ODU connectors.

Isn't it true that there isn't a day when we don't touch connectors such as plugs, USBs, LANs, and smartphone charging cables? A connector is a device used to transmit electricity, but how does electricity actually flow? In this document, I would like to briefly explain that mechanism. 【Contents (excerpt)】 ■1. The mechanism of electricity transmission through connectors ■2. Things that hinder the flow of electricity 　(a) Irregularities on the surface of metals 　(b) Insulating coatings on metal surfaces ■3. Defeating the hindrances 　(a) What can be done to eliminate irregularities on the metal surface? 　(b) What can be done about the insulating coating on the metal surface? *For more details, please refer to the PDF document or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Last month, we held a spring safety conference hosted by our company. We have compiled the details and atmosphere of the day into a PDF. We would appreciate it if you could take a moment to read it.

In recent years, as the importance of data integrity (DI) compliance in GMP environments has increased, there has been a growing call to deepen understanding of 21 CFR Part 11. This content introduces an on-demand presentation that organizes the background of Part 11, its relationship with DI, and its positioning in CSA guidance, while explaining the basic concepts of electronic records and electronic signatures. ■Content - Background and basic concepts of Part 11 - Relationship with data integrity (DI) - Positioning in CSA guidance - Basic requirements for electronic records/electronic signatures *This content is based on information as of March 17, 2026. *The information provided is intended for general informational purposes and does not guarantee specific compliance or suitability.
