1. Yagi-Uda ArrayInventor: Shintaro Uda
Description: Yagi-Uda array, commonly known simply as a Yagi antenna, is a directional antenna consisting of a driven element (typically a dipole or folded dipole) and additional parasitic elements (usually a so-called reflector and one or more directors). The reflector element is slightly longer (typically 5% longer) than the driven dipole, whereas the so-called directors are a little bit shorter. This design achieves a very substantial increase in the antenna's directionality and gain compared to a simple dipole.
Year Invented: 1926
2. Phototelegraphic
Inventor: Yasujiro Niwa and Masatsugu Kobayashi
Description: Yasujiro Niwa and Masatsugu Kobayashi invented a new type of phototelegraphic device, consisting of a separate transmitter and receiver and using a dedicated line, which would lay the technological foundation for the present-day fax machine.
In 1928, the newspaper industry was concerned over how to most quickly print pictures of the Showa Emperor's enthronement ceremony in its newspapers and report the news to the people of Japan. As a result of this competition, newspaper companies imported phototelegraphic devices, which did not perform well when tested. Without further time for development, newspapers bought Niwa and Kobayashi's machines, which were a great success. This was the first commercialization of these devices in Japan.
Despite the fact that introduction of technology from America and Europe formed the core of the cutting-edge field of electronics, the phototelegraphic field in Japan was established based on domestic technology. This field later contributed greatly to the development of Japanese fax technology.

3. Wood Hand Loom
Inventor: Sakichi Toyoda
Description: From an early age Sakichi Toyoda worked on improving looms. In 1891 he obtained his first patent for the Toyoda wooden hand loom. He went on to focus his efforts on the improvement and invention of looms, including a significant number of excellent motive and automatic machines.
In 1924, Toyoda invented the Type-G Toyoda automatic loom with non-stop shuttle change motion, the first of its kind in the world. The Type-G Toyoda automatic loom was a groundbreaking invention containing a number of features such as automatic thread replenishment without any drop in the weaving speed. Platt Brothers & Co., Ltd. of England, a world leader in the loom industry of the time, paid the 1929 equivalent of 1 million yen for transfer of the rights to the Type-G loom. Toyoda later used these funds as seed money to found Toyota Motor Co., Ltd.
As a result of Toyoda's inventions the quality of Japanese looms and textile products jumped to an internationally competitive level.

1. Cheugugi
Inventor: not available
Description: Cheugugi is a rain gauge. Made in 1441, it was first tool used to measure rainfall. Put on a stand, rainfall was used by a special measuring stick. It was used around the country and government officials would measure the rainfall and report to the government who would record the amounts. The original ones that were the first ever made cannot be found. The oldest ones found date back to 1770.
Year Invented: 1441
2. Myeonje Baegab
Inventor: not available
Description: It was invented following the French Campaign against Korea, 1866 and used in battle during the United States expedition to Korea in 1871. It was made of between 13 and 30 folds of cotton fabric and covered the upper torso.
Year Invented: Joseon Dynasty
Year Invented: Song – Yuan Dynasty
3. Papermaking
Inventor: Cai Lun
Description: Papermaking has traditionally been traced to China about AD 105, when Cai Lun, an official attached to the Imperial court during the Han Dynasty (202 BC-AD 220), created a sheet of paper using mulberry and other bast fibres along with fishnets, old rags, and hemp waste. However a recent archaeological discovery has been reported from Gansu of paper with Chinese characters on it dating to 8 BC.
While paper used for wrapping and padding was used in China since the 2nd century BC, paper used as a writing medium only became widespread by the 3rd century. By the 6th century in China, sheets of paper were beginning to be used for toilet paper as well. During the Tang Dynasty (AD 618–907) paper was folded and sewn into square bags to preserve the flavor of tea. The Song Dynasty (AD 960–1279) that followed was the first government to issue paper currency.

1. Hybrid Rice
Inventor: Yuan Longping
Description: Hybrid rice developed by famous Chinese agronomist Yuan Longping since the early 1970s is widely grown in China, with yields up to 12,000 kg per hectare. It has greatly increased yield on China's limited amount of arable land and been introduced to some Asian and African countries.
Year Invented: 1970
2. Compass
Inventor: not available
Description: For most of Chinese history, the compass that remained in use was in the form of a magnetic needle floating in a bowl of water. According to Needham, the Chinese in the Song Dynasty and continuing Yuan Dynasty did make use of a dry compass, although this type never became as widely used in China as the wet compass.
The dry compass used in China was a dry suspension compass, a wooden frame crafted in the shape of a turtle hung upside down by a board, with the lodestone sealed in by wax, and if rotated, the needle at the tail would always point in the northern cardinal direction. Although the 14th-century European compass-card in box frame and dry pivot needle was adopted in China after its use was taken by Japanese pirates in the 16th century (who had in turn learned of it from Europeans), the Chinese design of the suspended dry compass persisted in use well into the 18th century.Year Invented: Song – Yuan Dynasty

1. Swimming Trunks Capable of Preventing Swimmers From Drowning
Inventor: Yeh Chi Chang
Description: In an age where eco-friendly waste management is so needed, Yeh Chi Chang managed to create an innovative swimming trunk that was capable of preventing swimmers from drowning once it was inflated. This innovation is particularly noteworthy for South Africa as a large number of children’s lives are lost due to drowning. An item of clothing that doubles up as a life support system, is not only green friendly but truly innovative.
Year Invented: 2010
2. Bluetooth Telephone
Inventor: Cotron Corporation
Description: A telephone set has been composed of a base unit and handset throughout the time since the telephone was invented. The Cordless Earphones for Hands Free phone reception nowadays available in the market are supplemental. They have to adhere to the telephone base unit for control (i.e. to pickup or hang up a line) restricted within the range of the phone. This invention is to build a Bluetooth Earphone on a handset of a conventional telephone set the existing functions between telephone set and the PABX are kept unchanged. User can use the handset to pickup/end a call or directly pickup the Bluetooth Earphone to talk and end the call or when he docks the earphone to the base unit of the phone during conversation a phone amplifier function will be switched on automatically. (The handset can be built a Bluetooth handset too which will not affect the exiting functions at all.)
