Patent JP-S6110271-A (JP)
Title: Semiconductor device
Inventor: KOYANAGI MITSUMASA
IPC: H01L27/04
Filed: 1985-05-02
Abstract: PURPOSE:To improve the integration of MOS memories by reducing the area of a memory cell by a method wherein an accumulation capacitor is provided so as to at least overlap on a switching transistor. CONSTITUTION:A capacitor 2 to accumulate information is so arranged as to overlap on the switching transistor 1 with each other. For example, the second polycrystalline Si 14, an insulation film 16, and the third polycrystalline Si 15 constitute the accumulation capacitor 2. In this case, a large capacitor can be obtained by using a film of large dielectric constant such as an Si3N4 or a Ta2O5 film in addition to an SiO2 film or a multilayer insulation film of the combination thereof as the insulation film 16. Therefore, in the case of obtaining the same value as that of the accumulation capacitor used in the conventional memory cell, even a small area may be satisfactory.

Title: Method for locating partial discharge generated position
IPC: G01R31/08
Filed: 1992-03-19
Abstract: PURPOSE:To accurately and quickly locate a position, where partial discharge is generated, by supplying the output signals of two partial discharge signal detecting means to neutral networks, and using the signal hereby judged as the partial discharge signal. CONSTITUTION:The partial discharge signal generated inside of a cable 1 to be measured is taken from detecting impedances 5A, 5B, and is input to neutral networks 31A, 31B of a computing processing unit 30. In the neutral networks 31A, 31B, an input layer receives the signal waveform, and an intermediate layer analyzes the waveform thereof and experientially recognizes the signal waveform having the characteristic natural to the partial discharge signal waveform on the basis of a result of the previous study. In the case where the input signal waveform is judged as the partial discharge signal, the content 1 is output from the output layer. Only in the case where the content 1 is output from both the networks 31A, 31B, a position locating unit 32 computes the position location on the basis of a difference of the propagation time of the signal and the propagating speed thereof to locate the position, where the partial discharge signal is generated. Location is thereby automated and incorret recognition is prevented.
