Ōno Kōjin

Ōno Kōjin is a physics 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 Ōno Kōjin rather than just read about it. In short: Kojin Ono (Japanese: 大野光仁, Hepburn: Ōno Kōjin; born May 11, 1959, Tokyo) is a Japanese toy designer employed by Takara since 1980. Ōno's early designs included the Diaclone Walk-In Centre and Microman Acro Saturn. He designed most of the Diaclone Car Robot line (with additional design work by Shoji Kawamori) and Car Microman figures, which drew the attention of the U.S. toy company Hasbro.

Key takeaways

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

Reference excerpt

Kojin Ono (Japanese: 大野光仁, Hepburn: Ōno Kōjin; born May 11, 1959, Tokyo) is a Japanese toy designer employed by Takara since 1980. Ōno's early designs included the Diaclone Walk-In Centre and Microman Acro Saturn. He designed most of the Diaclone Car Robot line (with additional design work by Shoji Kawamori) and Car Microman figures, which drew the attention of the U.S. toy company Hasbro. Hasbro amalgamated the Diaclone and Microman figures and, along with a story treatment developed by Marvel, created the toy cult phenomenon known as the Transformers. Ōno continued to design Transformers throughout the 1980s until the end of the original series. Ōno designed most Transformers manufactured by Takara, including Metroplex, Fortress Maximus, and Powermaster Optimus Prime. Among the hundreds of Transformers that he designed, he considers the Decepticon Triple Changers Blitzwing and Astrotrain to be his finest achievements in toy design. Although Ōno no longer designs Transformer toys, as of 2005, he is still employed by Takara, where he continues to design figures in other Takara toylines.

Worked examples

Example 1 — a first encounter with Ōno Kōjin

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

In research: Ōno Kōjin appears in physics 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 Ōno Kōjin 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: Ōno Kōjin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1959 births, Japanese engineer stubs, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Ōno Kōjin 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.
