In this work, the electrical characteristics of organic thin film transistors with the surface-treated organic gate insulators have been studied. For the surface treatment, the simple rubbing technique was used. The field effect mobilities of the devices with PVP gate insulator was improved about four times as high as those of TFTs without the insulator surface treatment.

This paper shows experimentally one method of preventing porcelain insulators from salt accident likely to be caused in the region of sea coast. In this experiment some results that, if a conductor barrier is inserted into the flash over discharge path which is wetted by salt dissolved water, the flash over voltage found to be raised up, were gotten. This results may be actually applied to suspension insulator or bushing to prevent them from salt accidents.

The suspension insulators are subjected to harsh environment in service for a long time. Long term reliability of the insulators is required for both mechanical and electrical performances. We studied an analysing method to find out a deformation of brittle porcelain with a thermal expansion of simulation analysis and experimental results show that cement volume growths affect severely to b mechanical failure ageing.

Insulator strings can be frequently damaged by fault currents occured by lightning strokes, overvoltages and contamination of the insulators. So the Insulator damages may lead to extensive damages to transmission lines as well as power outages that have caused dangerous situations to occur. This paper suggests the characteristics of arcing horn in relation to the protection of insulators and basic design concepts of the arcing horn for transmission lines.

We have developed simplified processes for the formation of insulators, cathode separators and bus electrodes in PMOLEDs. The insulators and cathode separators are patterned simultaneously by a single layer of image reversal photoresist. And, the bus electrodes of low resistance are formed by the cathode separator and cathode metal. Using these simplified processes, we fabricated 1.17" $96{\times}RGB{\times}96$ panels and analyzed their performance and reliability.

Insulators of transmission line have been frequently damaged by lightning flashover. Arcing horns have been installed on string sets to protect insulators from the flashover. But reclosing number can be increased by the decrease of insulation strength and they are worrying it. Then this paper analyzes the installation effects of the arcing horn.
