The money developed by the Yubiwa Tube was to be committed to a fresh innovation. Though at a company display used in Ginza, Tokyo, following a success of the Yubiwa Tube, the brothers discovered a potential gap in the market for an all-electronic calculator. At that time, many calculators were mechanically employed by items and expected information operation with the utilization of a hand crank.
Moreover, some sophisticated electronic calculators offshore however worked with the usage of a power motor which created noise because the things spun at speed. Toshio's idea was to manufacture an all-electronic circuit based calculator utilizing a solenoid which may handle plenty of the issues that came with the existing mechanically based inventions. He needed to create his own calculator.
While functioning at Kashio Seisakujo on the sub contract perform, Tadoa and Toshio heavily used there morning time creating the calculator. Basic prototypes were shown to people and the feedback acquired served handle many problems. This is then iterated back in the prototypes. After a number of refined prototypes, Tadoa and Toshio finally developed Japans first electrical calculator in 1954.
However, there were difficulties once the friends approached the Bunshodo Company, a business focusing on company supplies. The Bunshodo Firm criticized the innovation, detailing the possible lack of multiplication functionality. The present calculator couldn't do continuos multiplication where the result of an original multiplication could be multiplied by another value. The friends returned to design, providing there two different friends Kazuo and Yukio to the development team. Yukio who was a mechanical design student served the team by designing the ideas and Tadoa and Kazuo did the production น้ำยาพอต
In 1956, six years of style, progress and pressing out issues and insects, the group were near to adding continuos multiplication to their innovation. However, Toshio decided to produce a big design change that would make the calculator totally electronic. The present solenoid option they had based their original thought on was to be exchanged with digital relays.
That had several advantages, among which created mass production of the merchandise more feasible. Certainly, the problem of relays was that they certainly were easily prone to fine particles and dust. Computer techniques which use relays, at that time often took up a whole space and had their own air filter process of some sort. This shown an entire new problem domain to the project.
