    摘要： In the production of electrically insulated coils which make up insulating layers, insulating material is wound around an electric conductor to form an insulating substrate, then impregnating varnish consisting of thermosetting resin is applied to the insulating substrate and hardened. In this electrically insulated coil production method, the impregnating varnish is made up of acid anhydride setting epoxy resin elements that include latent accelerators. These accelerators take more than 30 days to increase their initial viscosity by three times during storage at 25 degrees centigrade. After the insulating substrate is impregnated with the varnish, the substrate is heated at a temperature which will cause the impregnating varnish on the surface of the insulating substrate to lose its fluidity in under 30 minutes in order to preset the varnish. Next, the varnish is set at a heat at least 10 degrees centigrade lower than the presetting temperature and thereby, electrically insulated coils with high reliability are obtained.

    摘要： A sample to be measured having a semiconductor integrated circuit having interconnection lines is set on a scanning photoinduced current analyzer with one end of the interconnection line connected to a ground and the other end connected through a current amplifier to the ground. When a laser beam falls on part having a comparatively low thermal conductivity, such as a part having a void, of the interconnection line while the interconnection line is scanned with the laser beam, temperature distribution in the interconnection line changes at the part. The change in temperature distribution produces spontaneous thermoelectromotive force by the Seebeck effect to induce a current. The current amplifier amplifies the induced current, and then an image date converter converts the amplified current into image information in synchronism with the scanning operation of the laser beam. Since the photoinduced current can be measured without supplying a bias current to the sample to be measured, a current image corresponding to the photoinduced current can be formed to determine the position of a void even if the sample to be measured has a high resistance.
