How MINATA writes and checks its content

Every article, calculator, lookup table and download on MINATA follows the principles below.

Author

7+ years in production control, equipment maintenance, production engineering and automation equipment development at Japanese factories. Drawing on hands-on work from concept design to start-up, he supports Japan–Vietnam engineering, sourcing and communication. JLPT N1.

Sources

• Japanese standards (JIS) and official catalogues of Japanese manufacturers come first; ISO is used where it corresponds to JIS.
• Experience from Japanese factories explains the "why" — it never replaces figures from a standard.
• Internal documents of customers and partners are never quoted or named.

How we write

• No invented figures: numbers come only from sources; if a source does not give it, it is left out.
• Material is rewritten from a practical viewpoint, not translated line by line; Japanese terms are kept for lookup.

Calculators and lookup tables

• Formulas and factors are checked against Japanese/JIS sources, cited at each calculation step.
• Results are for preliminary selection. Before design or ordering, check the manufacturer's original catalogue.

Updates and corrections

• Each article shows the date it was last updated.
• If you spot an error, tell us through the Contact page with the article link. MINATA re-checks it against the source and corrects it.

See the corrections log

Scope

• The content is for reference and learning; it does not replace original standards, manufacturers' documentation or workplace safety rules.
