An adolescent and talented lathe owner newbie by name of Kashio Tadao began his studies at Waseda Koshu Gakka (now Waseda University) in Tokyo, The japanese. Gaining experience getting work done in a manufacturing plant (whilst studying) making general everyday items such as pots, pans and bicycle generator lamps, Tadao chose to 悅刻幻影 determine their own business (Kashio Seisakujo) subcontracting making microscope parts and equipment in 1946.
Tadoa had a younger brother Toshio, who was artistically proficient with extensive electrical knowledge. Tadoa from a young age shown admiration for the revolutionary efforts of Edison, who invented the lamp, and always told his family that she wanted to become an developer.
At this time, Tadio was a naturally proficient technician at the Ministry of Communications. He decided to leave his job at the Ministry of Communications to pursue his dream, the more ability testing and challenging job of an developer. Toshio joined Tadoa at Kashio Seisakujo and began utilizing his natural resourcefulness, trying several innovative ideas. One of which was the ring mounted cigarette holder (Yubiwa Pipe), which provided an opportunity of smoking a cigarette down to the nub whilst doing work.
We must remember that items in postwar The japanese where in short supply. This meant that Toshio had a potential market for his new innovation. Tadoa manufactured the holder on a lathe and the father of the two inlaws marketed the product. Orders began arriving for the water line and the product was a success.
Money created by the Yubiwa Water line was to be committed to a new innovation. Whilst at a business show held in Ginza, Tokyo, following the success of the Yubiwa Water line, the inlaws discovered a potential hole in the market for an all-electronic car loan calculator. At that time, most calculators were mechanically employed by equipment and required manual operation with the use of a hand prank.
Moreover, some advanced electronic calculators overseas still functioned with the use of an electric motor which made noise as the equipment turned at speed. Toshio’s idea was to electrical engineer an all-electronic enterprise based car loan calculator using a solenoid which will resolve a lot of the conditions that sported the current mechanically based pioneer technology. He wanted to make their own car loan calculator.
Whilst working at Kashio Seisakujo on the bass speaker contract work, Tadoa and Toshio heavily invested there evening time developing the car loan calculator. Basic prototypes were shown to people and the feedback received helped resolve many problems. This became then iterated back into the prototypes. After a number of refined prototypes, Tadoa and Toshio finally developed Japans first electric car loan calculator in 1954.
However, there were complications when the inlaws greeted the Bunshodo Corporation, a company devoted to office supplies. The Bunshodo Corporation criticized the creation, outlining the lack of multiplication functionality. The current car loan calculator could not do continuos multiplication where the result of a preliminary multiplication can be multiplied by another value. The inlaws went back to develop, bringing there two other inlaws Kazuo and Yukio to the development team. Yukio who was a mechanical engineering student served the team by designing the plans and Tadoa and Kazuo did the production.
In 1956, six years of design, development and ironing out problems and bugs, the team were close to adding continuos multiplication to their innovation. However, Toshio decided to create a big design change that would make the car loan calculator completely electronic. The current solenoid solution they had based their original idea on was to be swapped with electronic relays. This had a number of benefits, one of which made mass production of the product more feasible. Indeed, the disadvantage of relays was that they were easily susceptible to fine allergens and dust. Pcs which use relays, at that time usually took up an entire room and had their own air blocking system of some type. This presented a whole new problem domain to the project.
