Meisei Electric

Meisei 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 Meisei Electric rather than just read about it. In short: Meisei Electric Co., Ltd. (明星電気株式会社, Meisei Denki Kabushiki Kaisha) is a Japanese limited company which manufactures electronics and communications equipment.

Key takeaways

Meisei 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 Meisei Electric to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Meisei Electric from memory before moving on to harder problems.

Reference excerpt

Meisei Electric Co., Ltd. (明星電気株式会社, Meisei Denki Kabushiki Kaisha) is a Japanese limited company which manufactures electronics and communications equipment. Founded as a radio and electrical firm in 1938, it now specialises in geological and meteorological sensors, though it has also been involved in developing avionics and spaceflight technology. It is headquartered in the city of Isesaki in Gunma Prefecture, and operates a maintenance and personnel management subsidiary in the same area. In 2012, Meisei Electric was listed among "Asia's 200 Best Companies Under a Billion" by Forbes.

Products and operations Meisei designs and manufactures a wide range of electronics, including meteorological observation systems, road visibility meters, earthquake warning networks, landslide prediction sensors, satellite-mounted monitoring cameras and aviation control systems. It also operates a maintenance and personnel management subsidiary, Meisei Management Service Co. As of 2015, the company employs over 350 people. In 2012, Meisei Electric reported a net income of US$18 million, on revenue of $110 million. However, in 2014 the company reported a net loss of over $900,000 amid a significant fall in revenue. Meisei Electric returned to overall profitability in 2015, despite a further fall in revenue.

We-Wish CubeSat In 2012, Meisei Electric designed and built its first satellite, the We-Wish CubeSat. We-Wish, a miniature infrared monitoring satellite built using the standardised CubeSat architecture, was developed with the assistance of amateur radio operators, and its data was made available to Japanese high school students. It was carried to orbit along with several other CubeSats aboard Japan's Kounotori 3 spacecraft in July 2012, and was launched from the International Space Station on 4 October 2012. The CubeSat destructively deorbited as intended on 11 March 2013, after over 150 days of successful operation.

Worked examples

Example 1 — a first encounter with Meisei Electric

Start with the simplest possible case. Write down what Meisei 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 Meisei 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 Meisei 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 Meisei Electric

In research: Meisei 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 Meisei 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: Meisei Electric is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aerospace companies of Japan, Companies based in Gunma Prefecture, Companies listed on the Tokyo Stock Exchange, so understanding it makes those chapters shorter.
In everyday life: Look for Meisei 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.
