Furukawa Electric

Furukawa Electric is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Furukawa Electric rather than just read about it. In short: Furukawa Electric Co., Ltd. (古河電気工業株式会社, Furukawa Denkikōgyō Kabushiki-gaisha) is a Japanese electric and electronics equipment company.

Key takeaways

Furukawa Electric belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Furukawa Electric to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Furukawa Electric from memory before moving on to harder problems.

Reference excerpt

Furukawa Electric Co., Ltd. (古河電気工業株式会社, Furukawa Denkikōgyō Kabushiki-gaisha) is a Japanese electric and electronics equipment company.

History The company traces its origins to Furukawa Ichibei who founded Nikko Copper Works, a copper-smelting facility at Yokohama in 1884, which became part of Furukuwa Kogyo. A new company; Furukuwa Denki Kogyo, was formed in 1920, when it merged its copper business with its own Yokohama Wire Manufacturing Company, which it had acquired in 1908. So, the new company was able to combine its businesses of mining, refining, and making copper products, like wire and cable. Furukawa was a Japanese businessman who founded one of the fifteen largest industrial conglomerates in Japan, called Furukawa zaibatsu, to which Furukawa Electric belongs to this day. The company is listed on the Tokyo stock Exchange and is constituent of the Nikkei 225 stock index. Furukawa Electric aids CERN's experiments on the search for the Higgs boson with its superconducting magnet wires. The company's products also include superconductivity cables. As of July 2013 the company has 137 subsidiaries and affiliate companies across Japan, Europe, North and South America. In 2025, Furukawa Electric will integrate its global fiber optic cable operations under a new brand: Lightera.

Worked examples

Example 1 — a first encounter with Furukawa Electric

Start with the simplest possible case. Write down what Furukawa Electric claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Furukawa Electric before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Furukawa Electric ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Furukawa Electric

In research: Furukawa Electric appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Furukawa Electric in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Furukawa Electric is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies in the Nikkei 225, Companies listed on the Tokyo Stock Exchange, Electrical equipment manufacturers, so understanding it makes those chapters shorter.
In everyday life: Look for Furukawa Electric outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
