IPC: H03M7/40
Filed: 1991-10-23
Abstract: PURPOSE:To shorten time for a decoding processing concerning a data decoding system to restore compressed data. CONSTITUTION:An input code is retrieved from a second dictionary by a retrieving means 3a of a second decoding means 3. When the code is detected, a character string output means 3b outputs a decoded character string corresponding to the input code from the second dictionary. Reversely when no code is detected, a first decoding means 2 retroactively decodes the input code by using a first dictionary and outputs the decoded code. Afterwards, a second dictionary registering means 4 registers the pair of the first character of this decoded character string and the former restored character string on the second dictionary together with the input code for the next decoding processing and therefore, the restored character string corresponding to the input code can be considerably speedily obtained.

Patent JP-H11121749-A (JP)
Title: Thin-film transistor and liquid crystal display device
Inventor: AZUMA RYOTA
IPC: H01L29/786
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a thin film transistor whose reliability is improved. SOLUTION: In a state where an n-type thin film transistor 28 is on, a channel region 8 undergoes weak inversion to the bottom part, and current flows between a source region 11 and a drain region 12. Since a reverse bias is applied to the p-n junction part formed between a p-type semiconductor layer 3 and a channel region 8, no current flows between a transparent conductor layer 2 and the drain region 12. Since high energy is imparted to holes formed in the drain region 12 by impact ionization, the holes can be made to flow out into the transparent conductor layer 2. In an off state, the negative gate voltage is applied to a gate electrode 21. Therefore, the current does not flow between the source region 11 and the drain region 12 and between the transparent conductor layer 2 and the drain region 12.  Only the holes formed by the impact ionization can escape to the transparent conductor layer 2. The abnormal increase of the drain current is prevented, and the deterioration of the characteristics is suppressed.
