CONSTITUTION:The principal material of the title material is ZrB2 powder, having the grain size of 44mum or less, small in electric resistance and excellent in resistances to high temperature and oxidization. The content of ZrB2 is limited within the range of 50-90%. When the content is 50% or less, the intrinsic resistance thereof becomes high. On the other hand, when the content is 90% or more, there is a problem in plasticity. 40-8% of phenolic resin is added as binder except the principal material ZrB2. When it is 40% or more, oxidizing loss becomes remarkable and when it is 8% or less, the adhesive power of the title material is insufficient. 2-10% of alcohol solvent is added in order to realize the plasticity thereof. When it is 2% or less, the plasticity is insufficient and when it is 10% or more, flowing property is too high in a degree that it is hard to interpose the title material between a nozzle and an electrode and there is a possibility of outflow.

Filed: 1993-04-21
Abstract: PURPOSE:To improve the picture quality by setting a gamma correction characteristic of a video signal to a characteristic in response to a pattern so as to apply gamma correction proper to the content of a video signal. CONSTITUTION:An arithmetic operation section 2 receiving plural parameters from a pattern discrimination section 1 uses the parameters to make arithmetic operation.
