Abstract: PROBLEM TO BE SOLVED: To provide a field emission element capable of preventing an increase in electric power consumption, and capable of improving reliability of the element. SOLUTION: In a three-pole type field emission element, the field emission element has a gate electrode 205, an emitter 204, and an anode 207, and is constituted so as to connect a resistance 209 between the gate electrode 205 and an external terminal 206 of this gate electrode. A resistance value of this resistance 209 is set so as to satisfy a condition of being larger by about 10 times or more than a resistance value up to an external terminal 206 of the gate electrode from the gate electrode 205, and smaller in characteristic time than an inverse number of a driving speed. That is, a resistance characteristic of this resistance 209 is set so as to become small such as having no influence on a field emission characteristic in normal operation, and become large such as being capable of controlling a quantity of leakage current generated in a state of electrically connecting a field emission electrode to the other electrode.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for embedding and extracting digital watermarks based on wavelets which is robust to external attacks while being capable of minimizing a degradation in picture quality caused by embedding of the watermarks. SOLUTION: The embedded watermarks embedded in DC component domains of wavelet-transformed domains can be robust to external attacks such as compression in the case of embedding and extracting watermarks for copyright protection. The high-frequency dependency of pixels in a DC component domain determined as a target domain, in which watermarks are to be embedded, is calculated, in order to embed the watermarks in the target domain in the order of pixels having a higher high-frequency dependency. Accordingly, there is an advantage in that it is possible to minimize a degradation in picture quality caused by the embedding of watermarks in the DC component domain. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To enhance a network efficiency by allowing a base station to capture a code such as a preamble transmitted from a plurality of terminals through a reverse common channel from all available preamble signatures so as to reduce undesired data transmission and an interference signal. SOLUTION: A base station 200 captures a code such as a preamble transmitted from a plurality of terminals 100 through a reverse common channel from all available preamble signatures. The base station 200 transmits a capture display signal denoting an acquisition state of the preamble signatures sent from each terminal 100 through a forward common channel. Terminal 1st and 2nd decision sections 110, 160 of each terminal 100 decide whether the received acquisition state signal is user information data or re-transmission of the preamble with enhanced power. Thus, a proper power level is quickly approached and an excellent time delay characteristic is obtained.
