Key takeaways

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

Reference excerpt

Oki Electric Industry Co., Ltd. (沖電気工業株式会社, Oki Denki Kōgyō Kabushiki-gaisha), commonly referred to as OKI (), is a Japanese information and communications technology company, headquartered in Toranomon, Minato-ku, Tokyo and operating in over 120 countries around the world. OKI produced the first Japan-made telephone in 1881, and now specializes not only in developing and manufacturing telecommunications equipment but also in information products and mechatronics products, such as automated teller machine (ATMs) and printers. OKI had a semiconductor business, which it spun off and sold to Rohm Company, Limited on October 1, 2008. OKI Data, a subsidiary, which markets its products under the OKI brand, is focused on creating professional printed communications products, applications and services. OKI Data provides a wide range of devices, from printers, faxes and multi-functional products to business applications and consultancy services. Through its American business arm, OKI Data America markets the OKI proColor Series, a line of digital production printers designed specifically for the graphic arts and production market in North America to offer print services for color-critical applications.

Company history

OKI of telecommunication (1881–1950s)

Founding The company was founded by Kibataro Oki (1848–1906), an engineer formerly employed at a Kobusho (Ministry of Industry) factory. In 1877, only a year after Alexander Graham Bell's invention, Kubusho had started an effort to make telephone receivers by reverse engineering and Oki was in the team that came up with the first prototype. In January 1881, convinced that the nation was about to enter the age of communications, Kibataro Oki founded Meikōsha, which was later renamed OKI. The company manufactured the first telephone in Japan in 1881, five years after Bell invented the phone, and exhibited a silver-award-winning lacquer-coated wire at the 1885 International Inventions Exhibition in London.

Early years OKI contributed immensely to the proliferation of phones in Japan under the country's Telephone Expansion Plans. The company saw the need of automatic exchanges as well, as phones became common. Asano Soichiro of Asano zaibatsu, a predecessor of the Fuyo Group, was elected to chairman in 1912.

Pre and post wars During World War I, wartime demand brought large profits to OKI as demand for telephone service increased. A strong demand emerged for the PBX (Private Branch Exchange), the largest system of which in Japan installed by OKI. In addition to business from Japan, overseas business also grew, providing railroad-type printers, portable telephones and electric wires outside Japan. From around 1920, OKI achieved notable advances in its technical development of the common-battery switchboard. Asano Soichiro's son was appointed to the next chairman in 1931. In the late 1930s, OKI's plants were used towards meeting the military demand for goods, having major effects on OKI's business, such as building new production plants, and increasing its capital as well as the number of its affiliates. OKI increased its production capacity after WWII to restore magnetotype telephones and exchanges that were damaged during the war, OKI endured great difficulties as it moved toward rebuilding itself. On November 1, 1949, Oki Electric Industry Co., was established to succeed the former entity Oki Electric Co., Ltd. Two years later in November 1951, OKI's shares were listed on the Tokyo Stock Exchange. It was also at this time when OKI started mass-producing the “Type-4 telephone,” which was called a "symbol of Japan’s postwar reconstruction". In 1956, it was the first to produce a 100-line Ericsson-type crossbar-switching systems for commercial use.

OKI of electronics (1960s–1980s) OKI gradually transformed itself into an electronics company from the second half of 1960s into the 1970s.

1960s To respond to the high-level economic growth Japan was experiencing, OKI needed to speed up its business operations and clarify responsibilities. OKI began producing and supplying business machines such as teletypewriters, and perforation typewriters. In June 1961, OKI launched OKITYPER-2000, an electric teletypewriter that could simultaneously make perforation tapes and book entry forms. The company also developed and sold various general-purpose computers such as OKITAC-5090, the first domestically produced computer to use core memory. In 1964 OKI developed OKISAVER, a terminal for online deposits which was provided to financial institutions.

1970s In addition to minicomputers such as the OKITAC series developed in the mid-1960s, OKI began supplying various I/O devices, electroprinters, and dot printers, mainly to the financial industry in the 1970s. OKI's business at this time included cash dispensers (CDs), automatic depositors (ADs) and automated teller machines (ATMs).

In this period, OKI expanded its overseas business providing telecommunications systems to countries in the Middle East, Central and South American countries as well as other Asian countries. In 1972, OKI established Oki Data Corporation (ODC: today's OKI Data Americas), a Japan-US joint venture located in Philadelphia, to develop the DP100, dot printers. In 1975, OKI developed the world's first automobile telephone system together with Bell Labs. This was the beginning of OKI's wireless technology, and, as of 2009, OKI keeps expanding this technology into vehicle-to-vehicle communications and ETC (Electronic toll collection) technologies.

1980s

In May 1980, OKI launched the IF-800 series, which was a successful business-use PC business. It also added a facsimile business unit in search of private sector demand. In 1982, OKI introduced the world's first cash-recycling ATM, allowing deposited banknotes to be immediately used for withdrawal.

Worked examples

Example 1 — a first encounter with Oki Electric Industry

Start with the simplest possible case. Write down what Oki Electric Industry 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 Oki Electric Industry 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 Oki Electric Industry 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 Oki Electric Industry

In research
Oki Electric Industry 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 Oki Electric Industry 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
Oki Electric Industry is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1881 establishments in Japan, Aerospace companies of Japan, Companies in the Nikkei 225, so understanding it makes those chapters shorter.
In everyday life
Look for Oki Electric Industry 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.
