摘要:
A microchannel plate has a platelike photosensitive glass substrate and a plurality of microchannels formed separately from each other and extending across the thickness of the substrate. A secondary electron-emission surface is formed on an inner surface of each of the microchannels. Accelerating electrodes formed on two opposite sides of the photosensitive glass substrate, so as to be partially in electrical contact with the secondary-emission surface. The microchannels are formed by applying ultraviolet rays to the substrate through a mask and removing irradiated portions of the substrate by etching.

摘要:
When an antenna receives a signal, the signal is inputted to delayers through a frequency converter, A/D converters, quadrature demodulators, filters and simultaneously is inputted to a MUX. The receiving signal inputted to the MUX is transmitted to an interference canceler panel, and the interference canceler panel generates both an interference replica signal and a symbol replica signal. The interference canceler panel demodulates the receiving signal for a channel corresponding to the symbol replica signal using both the interference and symbol replica signals. The interference replica signal generated by the interference canceler panel is transmitted to a transmitting/receiving panel and is inputted to interference elimination units. The interference elimination units eliminates interference components by subtracting the interference replica signal from the receiving signal delayed by the delayers and transmits the signal to a baseband signal processing panel.

In a mobile communicating system, a mobile terminal has a position information detecting unit for detecting position information, a position information transmitting unit for transmitting the position information to an information center, an up-load data transmitting unit for transmitting up-load data to the information center and an information/service utilizing unit for utilizing information/service from the information center, whereas the information center has an accumulating unit for accumulating information/services, a retrieving unit for receiving the position information from the mobile terminal to retrieve the information/services in the accumulating unit, an accumulation controlling unit for accumulating the up-load data in the accumulating unit, and an information/service transmitting unit for taking out the information/service retrieved by the retrieving unit from the accumulating unit and transmitting it to the mobile terminal, thereby providing not only map information showing the current position of the mobile terminal but also information of facilities on the map to the mobile terminal.
摘要:
An improved multi-bit memory cell includes a storage capacitor and a switching element coupled to one of the terminals of the capacitor. The switching element includes a first switching component having a positive threshold, and a complementary switching component having a negative threshold. Because the switching element is constructed in this manner, noise generation caused by activation of the switching components is significantly reduced, and cut-off effects are eliminated. Both of these factors contribute to the memory cell's ability to store more bits of information than prior art memory cells.
