This item is a calculator made by Dr. Tathujiro Sasaki, Mr. Ryo Shiga and others for working out nine simultaneous linear algebraic equations. The original machine was designed and made by Dr. John B. Wilbur in 1936. Some machines of this type were made in the world. However all of them seemed to disappear except this Japanese one. This report shows some details of this machine, which was researched for an exhibition"The Heroes of Information Age"at the National Science Museum in between March 6 and June 5,2001.

The development process of the radar technologies in Japan consisted of four stages as (1) at a dawn before 1941,(2) inspection tour to Germany in 1941,(3) beat with gun radar and (4) out of gear. Through this stage, each kind of radar was made by The Naval Technology Laboratory. A 10 cm magnetron was developed individually on the first stage. A application of radar system came from Germany. However some gun radars had been reproduced based on US and UK radar. The Finally a technological innovation was not happened.

The faradization apparatuses in Meiji Era played an important part for the history of electrification in Japan. However there are few data about machines, makers of them, amount of productions and etc. Investigating circuits, structures, dimensions of these machines and unique characters, this research offers some basic data about three machines of battery type and about two Magneto-Electric Machines that were preserved in the Edo-Tokyo Museum, the Toyota Commemorative Museum of Industry and Technology and the National Science Museum. Three battery machines were made by each makers individually in Japan but their structures were very similar. Two Magneto-Electric Machines made by foreign makers were in the same situation too.
