Secom

Secom is a engineering 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 Secom rather than just read about it. In short: Secom Co., Ltd. (セコム株式会社, Sekomu Kabushiki-gaisha) is a Japanese security company headquartered in Tokyo, Japan.

Key takeaways

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

Reference excerpt

Secom Co., Ltd. (セコム株式会社, Sekomu Kabushiki-gaisha) is a Japanese security company headquartered in Tokyo, Japan. It has operations in Japan, United Kingdom, Australia, New Zealand, South Korea, Taiwan, China, Thailand, Vietnam, Malaysia, Singapore, Indonesia, and Myanmar.

History The company was founded in 1962 and operated under the name Nippon Keibi Hosho until 1983. It initially offered security services such as patrolling services and static guard services. In 1966, the company developed Japan’s first on-line security system. In 1983, Nippon Keibi Hosho adapted the name Secom, which was originally used only as a brand name of the company. The Secom name "was coined as a contraction of 'security' and 'communication', the concept of this brand was to build 'a new security system collaborating people and science'”.

Worked examples

Example 1 — a first encounter with Secom

Start with the simplest possible case. Write down what Secom claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Secom 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 Secom 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 Secom

In research: Secom appears in engineering 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 Secom 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: Secom is common in secondary-school and first-year university syllabi. It links to neighbouring topics Business services companies established in 1962, Companies based in Tokyo, Companies in the Nikkei 225, so understanding it makes those chapters shorter.
In everyday life: Look for Secom 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.

Frequently asked questions

What is Secom in simple terms?

Secom Co., Ltd. (セコム株式会社, Sekomu Kabushiki-gaisha) is a Japanese security company headquartered in Tokyo, Japan.

Why does Secom matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
