TANAKA to Provide Pure Gold, Pure Silver, and Pure Bronze Medals for the Tokyo Marathon 2020 on March 1

TOKYO, Feb 10, 2020 – (ACN Newswire) – TANAKA HOLDINGS Co., Ltd. (Head office: Chiyoda-ku, Tokyo; Representative Director and CEO: Akira Tanae) will provide and donate gold, silver, and bronze medals to the top three men and women finishers of the marathon and wheelchair marathon events at the Tokyo Marathon 2020 (a total of 12 medals). The Tokyo Marathon 2020 is organized by the Tokyo Marathon Foundation, and will be held on March 1, 2020; the wheelchair marathon has been an officially sanctioned as an international event since 2016.





The Tokyo Marathon medals provided by TANAKA HOLDINGS are made from pure gold, pure silver, and pure bronze – this makes them unusual and unique among sports medals and rarities of considerable value. The medals presented to the top three finishers are approximately 65 mm in diameter, with the pure gold medal weighing approximately 180 grams, the pure silver medal approximately 100 grams, and the pure bronze medal approximately 85 grams.

For the 14th edition of the Tokyo Marathon, the medal designs are based on traditional Edo komon patterns that have been used to decorate kimono ever since the Edo period. Six distinctive patterns – sakura (cherry blossom), shippo tsunagi (seven treasures), seigaiha (blue ocean waves), asanoha (hemp leaf), kanoko (fawn), and kouji tsunagi ("kou"-character) – are combined on the medals to resemble the collar of a kimono, signifying a fusion of this unbroken Japanese tradition with the overlapping thoughts of runners and the spectators who support them. "Running" is the key visual concept of the Tokyo Marathon 2020, and people who enjoy running in all its forms will gather at the event. With their traditional Edo motifs, the medals communicate the message that "the Tokyo Marathon will be the starting point for many diverse stories" in a design of great originality.

The medal ribbons feature a design based on the tapestry-like Tokyo Marathon logo, in which each thread represents an individual runner, volunteer, and spectator. The reverse sides of the gold, silver, and bronze medals that will be presented to the top three finishers of each marathon event depict the course map and the TANAKA PRECIOUS METALS logo.

The TANAKA KIKINZOKU Group has produced the winner medals and finisher medals for every Tokyo Marathon since the first was held in 2007. The Tokyo Marathon was added to the World Marathon Majors (currently the Abbott World Marathon Majors) in 2013, attracting global attention as one of the world's six premier marathons. The TANAKA KIKINZOKU Group has produced and sold various commemorative medals other than for the Tokyo Marathon, including the official commemorative medals for the 1964 Tokyo Olympic Games. The TANAKA KIKINZOKU Group will continue to produce medals made of precious metals and support various events in a way unique to the Group.

Measuring the wear and tear of metals

Tsukuba, Japan, Feb 6, 2020 – (ACN Newswire) – For the past 50 years, researchers at the National Institute for Materials Science (NIMS) have been conducting detailed short- and long-term testing of a wide variety of structural materials manufactured in Japan to ensure they can withstand long-term stresses. Now, NIMS scientists have reviewed this data, in the journal Science and Technology of Advanced Materials, summarizing the institute's major findings.

In 1966, NIMS's predecessor, the National Research Institute for Metals, launched its 'creep data sheet project'. The aim of this project was to determine the stress required to rupture heat-resistant steels and alloys in 100,000 hours (about 11.4 years) at high temperatures. This 'creep rupture strength' data was initially needed to determine the allowable stresses metals could be exposed to in power plants. But more recently, this data has been used to assess how much longer power plant parts have before they begin to wear and tear.

Just over a decade later, in 1978, NIMS also began assembling what has become a huge database of fatigue properties of structural materials used in numerous industries, including automobiles and aircrafts. Fatigue describes how cracks propagate in a metal over time. Fatigue tests involve placing a metal sample under repetitive loads, called cycles, to see how long it takes for a crack to develop and propagate. These tests are conducted at room temperature and high temperatures. Samples are exposed to a relatively small number of cycles (in the range of 10 million cycles) or up to 10 billion cycles, lasting for several years.

NIMS data has revealed that the long-term creep strength of materials varies, and that scientists need to choose the type of analysis method for creep rupture data according to the type of material. How creep happens in materials during testing not only depends on the amount of stress applied, but also on the temperature conditions. The researchers have found that materials react differently to varying temperature depending on their chemical composition, the amounts of minor elements in them, and the crystal grain size. Ferritic heat-resistant steels, which are commonly used in thermal power plants, were found to have very long-term, inherent creep strength. But this creep strength is dependent on the amount of minor solutes present in the steel.

Fatigue limits, on the other hand, are affected by a metal's tensile strength and hardness. Interestingly, NIMS scientists have found that some metals can last for an incredibly long time without forming cracks as long as they are constantly exposed to room temperatures. These same metals, however, would eventually form cracks if exposed to the same stress but at high temperature.

Up until now, the creep and fatigue data sheets developed at NIMS have been used mainly for industrial purposes. The institution is now aiming to improve accessibility so the data can also be used by academics.
