The Study of Type Wheel as the Impact Type High-speed Computer-printer

It was found that carbon with an extremely steady characteristic can be obtained by baking the furan resin, one sort of thermoset high polymer in the condition of 3-4°C/h up to 200°C and 7-8°C/h above 200°C respectively in N₂ gas and He gas atmosphere. Relatively few researches have been done so far of the high molecule carbon as a bulk material such as the one we did. The application as an industrial material can be expected by further elucidation of physical properties.

In this report, we will report the study on the impact style type wheel for the high-speed printer. Impact style high-speed printing type with a lower weight and a smaller wearing loss as compared with the metal type could be produced from carbonized furan resin through a simpler production process. The printing wear loss of carbonized furan resin is nearly zero by 1,800,000 times printing.
