Important Inventive Achievements] Edison and his inventions.

Synchronous transmitter.

Because Edison himself was a telegraph technician, he set out to improve the traditional telegraph and create a double transmitter, and in 1874, he developed a quadruple transmitter, that is, a synchronous transmitter. At a time when radio was not yet developed, the synchronous transmitter was a major breakthrough.

Improved ** machine.

We all know that the modern ** was invented by Bell, in fact, ** can clearly receive and speak, thanks to Edison's experiments again and again, breaking through the traditional rut, manufacturing a toner transmitter, in one fell swoop to improve the sensitivity, volume, reception distance.

Phonograph. One night in December 1877, the staff of the Monroe Garden Laboratory shivered slightly, not because of the cold, but because they heard it, the phonograph left a sound for the first time, this great invention, without much introduction, everyone can understand how widely it has been used. Later, Edison improved the phonograph several times until he changed the drum type to the bakelite turntable.

Electric light - messenger of light.

At the beginning of the 19th century, people began to use gas lamps (gas lamps), but the gas was supplied by pipes, and it was very easy to cause accidents if the gas leaked or blocked. In fact, Edison set himself the impossible task: to create a system to supply electricity, in addition to improving the lighting.

So he and his friends worked tirelessly to do more than 1,600 experiments on heat-resistant materials and more than 600 kinds of plant fibers before making the first carbon light bulb, which can burn for 45 hours at a time. Later, he continued to improve the manufacturing method on this basis, and finally launched a bamboo light bulb that can ignite for 1,200 hours.

Copier. At first, Edison's invention of paraffin paper was only widely used in food, candy packaging materials are closed, and later he tried to carve the outline of the text on the wax paper to form a paraffin lettering paper plate, under the paper board on the white paper, and then use the ink roller to roll from the engraved paraffin paper, a wonderful thing happened, the white paper appeared clear handwriting. Since then, it has undergone many improvement tests.

In 1876, Edison began mass production of the photocopier he invented, and all of a sudden, institutions, schools, institutions, and organizations all adopted this kind of wax paper mimeograph. Due to the popularity of Edison's photocopier, which became popular all over the world, Edison deeply experienced that he should invent something that people generally and deeply needed.

Edison made more than 2,000 inventions and patented more than 1,000 patents in his lifetime.

The main things invented by Edison were: phonographs, movie cameras, moving movie projectors, sound films, electric lights, "nickel-iron alkaline batteries" and so on.

1. Movable movie camera.

In 1889, Edison invented a movable motion picture camera, which used a pointed gear to drive a 19 mm wide piece of unperforated tape, which was controlled by a ratchet wheel to move the tape intermittently and perforate at the same time. The camera is driven by a motor and the shader shaft is linked to a gramophone, which records the sound while the camera is running, and can take images continuously.

2. Movable movie projector.

In 1891, Edison invented the movable film projector, which was an early film display device, and introduced the basic method of film projection, by using an engine in front of the light source to rotate the film strip with continuous ** at high speed, thus creating the illusion of activity, and the light source projected the ** on the film onto the screen.

3. Electric lights. In October 1879, Edison successfully made an incandescent light bulb with carbon fiber as the filament, called the "carbonized cotton silk incandescent lamp", and then put it into production in large quantities, and established a company to set up corresponding infrastructure such as power stations and transmission grids, which soon made electric light widely used in the United States. During this period, he continued to improve the technology, and finally decided to use tungsten filament as the filament, called "tungsten filament", and finalized it into use today, Edison has become recognized as the inventor of the electric light.

4. Sound movies.

In 1910, Edison invented a movie camera composed of a gramophone and a camera, under the energy of the motor, the blackout crankshaft of the camera was linked to the gramophone, and the phonograph could record the sound when the camera was running. During the projection, the phonograph runs in sync with the picture, so that the sound and image appear at the same time.

5. Gramophone.

On August 15, 1877, Edison asked his assistant to make a "strange machine" composed of a large cylinder, a crank, a receiver and a diaphragm according to the pattern, after making it, Edison took out a piece of tin foil, rolled it on a metal cylinder engraved with a spiral groove, let one end of the needle gently rub the tin foil to rotate, and the other end was connected to the receiver, and then Edison shook the crank, sang to the receiver, and then put the needle back in its place, and then shook the crank, and then the machine played Edison's voice back. In December, Edison publicly demonstrated this "tin foil cartridge phonograph", which caused a sensation all over the world.
