Reference excerpt

Riso Kagaku Corporation (理想科学工業株式会社, Risō Kagaku Kōgyō Kabushiki-gaisha) is a Japanese corporation which is the inventor, manufacturer, and distributor of the RISO Printer-Duplicator, a.k.a. Risograph. This device automatically creates a stencil-type master (from a paper original or digital file), thereby enabling it reproduce single-colour documents at high speed and low cost, in a machine that has a small footprint and a relatively low purchase price. The firm was established in Tokyo, Japan, where it continues to maintain its headquarters today. With sales in over 150 countries, Riso is a billion-dollar company. The company maintains a foundation that donates equipment around the world primarily to educational institutions. In Japanese, 'Riso' means 'ideal' and the word 'Kagaku' means 'science.' Noboru Hayama, the company's founder, started his business by mixing inks at his kitchen sink just after World War II, and in 1946 established a mimeograph printing company, whose first product was its signature duplicator. Over the next few years, Mr. Hayama expanded his company to the area of manufactured emulsion inks, stencil masters, and other duplicating products.

Sponsorships The company sponsors the J.League football club Kashima Antlers with the RISO logo appearing on the back of the club's shirt.

Worked examples

Example 1 — a first encounter with Riso Kagaku Corporation

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

In research: Riso Kagaku Corporation appears in computer 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 Riso Kagaku Corporation 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: Riso Kagaku Corporation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies listed on the Tokyo Stock Exchange, Computer companies of Japan, Computer hardware companies, so understanding it makes those chapters shorter.
In everyday life: Look for Riso Kagaku Corporation 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.
