    first practical endoscope

    Background

    Hello, my name is Kohei Sohara and today I will talk about Olympas Olympus corporation and it which created a first practical endoscope.

    In the first place, Olympas Olympus started to develop a first practical endoscope because Uzi Tatsumi who was a surgeon in Tokyo University hospital asked Olympas them  to make a practical endoscope it.

    At that time in 1950s, there were not  no medical equipment which doctor want to can use toyour to patients 　well. If a doctor wanted to look at a medical equipment the body of the patient, doctor only they had to  incise body. So, the patient’s body burden is large would have a large burden  and it is so difficult for doctor early detected cancer to find a cancer early.

    Before 1950, in 1932 there was an endoscope which developed by Rudolf Schindler developed. But it was not practical because it was so hard to use and have had a risk of leakage of electricity because it was used a leakage of electricity.
    So, surgeon “Uzi Tatsumi” and engineers of Olympas Olympus started to make a first practical endoscope having an ideal which is

    “ not a no risk”, “not a no patient’s body burden”, “short exposure time” and “clear picture”.

    Research Question

    How did Olympas make the first practical endoscope?

    Methods and Data
    ・In 1950, Uzi Tatsumi ask engineer of Olmpas to developed the first practical endoscope.
    ・At first they heard that doctors lived in japan want the endoscope.
    ・They developed the dedicated small camera to endoscope.
    ・They used the optical fiber to endoscope.
    ・They developed the first practical endoscope.

    Conclusions and Future Research
    Developing the practical endoscope contributed to lower death late of cancer. It is easy for doctor and it avoided physical burden of patient because it gat smaller

    Hello my name is ~~~ and .Today I’d like to talk about Thomas Alva Edison and his invention, the incandescent filament lamp.

    In 1878, Edison began working on a system of electrical illumination, something he hoped could compete with gas and oil based lighting. He began by tackling the problem of creating a long-lasting incandescent lamp, something that would be needed for indoor use.

    His He began the serious incandescent light bulb research began in 1878, filing and filed his first patent "improvement In Electric Lights" in October of that year.later that year…”Improvement In Electric Lights” in October 1878. His experiments involved the fabrication and testing of many different metal filaments, including platinum.

    You have some background information on incandescent filament lamp.
    Now lt’s let's look at the focus of on Edison’s research.

    Research Question
    　How can I light the lamp for a long time?

    Methods and Data
    　In 1879, Edison conducted an experiment.

    1.Edison returned to a carbon filament.
    2. He successfully tested a filament that burned for 13.5 hours.
    3.He continued to improve this design and used a carbon filament or strip coiled and connected to platina platinum contact wires
    4.This was the first commercially practical incandescent light.

    Conclusions and Future Research
    　The incandescent filament lamp is perhaps the most celebrity invention ever given to for Edison. Even people who are disadvantaged were able to a poor person can light the lamp by mass production of filament lamp.
