IPC: H03M7/40
Filed: 2002-01-31
Granted: 2003-06-11
Abstract: Wireless communication coding method for representing digital data with variable length signal. The invention is a wireless communication coding method for representing digital data with variable length signal. The coding method first defines a unit time T. For the high quasi-bit in the continuous digital data stream, use N unit time (N x T) to transmit. For the low quasi-bit in digital data, use M unit time to transmit (M x T). By means of applying different transmission time length to signals with different high and low quasi-bits, it can dramatically shorten the entire transmission time of data during huge amount of data transmission so as to lower power consumption of transmitter and receiver and maintain the synchronous transmission request of transmitting side/receiving side of signals.

Title: Cathode material for solid oxide fuel cell
Inventor: YU HE-JIE
IPC: H01M8/02

Granted: 2004-06-11
Abstract: A cathode material for a solid oxide fuel cell uses an oxide having a high oxygen vacancy concentration and a high electric conductivity as cathode to accelerate the adsorption of oxygen molecules and the diffusion of oxygen ions in order to achieve the objective of reducing the internal resistance of a cell, i.e. reducing the over-potential of cathode and increasing the power generation efficiency of the fuel cell. The oxide has an empirical formula of Ln1-xAxCu1-yByO2.5±delta, in which Ln is a lanthanum element, A is an alkaline earth element, B is a metal element, and the A position is added with a foreign valent alkaline earth metal to promote a portion of copper to be converted into a tri-valent copper, thereby forming a pseudo-perovskite structure with a regular oxygen vacancy arrangement. The catalysis of the cathode electrode can be used to accelerate the cathode reaction. Electrons transmitted from an external circuit combine with O2 to form O2- which diffuses to the electrolyte to react with hydrogen at the anode.

Title: Semiconductor memory
Inventor: MORI KAORU
IPC: G11C11/403
Filed: 2003-01-24
Granted: 2004-04-21
Abstract: An operation control circuit sets an inactivating timing of sense amplifiers activated in response to a read request, a write request, or a refresh request, to the timing a maximum possible quantity of signals which can be output from the sense amplifiers operating in response to the refresh request is transmitted to memory cells. Tailoring the activating period of the sense amplifiers to a refresh operation can reduce access time. A refresh control circuit generates a predetermined number of refresh requests consecutively to refresh all of the memory cells before extending the cycle of generating refresh requests. When refresh requests occur consecutively, the refresh frequency can be lowered to reduce power consumption. As a result, access time can be reduced without increasing power consumption during the standby mode.
