Abstract: PURPOSE: To make it possible to use a full-charge detector for both an NI-Cd battery and an Ni-MH battery, by generating a full-charge control signal when a variation in terminal voltage decreases and at the same time a variation in temperature increases. CONSTITUTION: A charging current from a current input terminal 2 is controlled by a constant-current circuit 3 and fed to a battery 1 to be charged.

When the variation (ΔV) at a certain moment decreases at the next moment and the variation (ΔT) in temperature increases at the next moment, a control output signal for indicating full charge of the battery 1 is generated. As a result, the full- charge detector can be used for an NI-Cd battery and for an Ni-MH battery.

Title: Multi-carrier signal transmission device and multi- carrier signal reception device
Inventor: IWAMI HIDEKI
IPC: H04J11/00
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To detect a preamble signal with a processing by less delay time by extracting information required for synchronously acquiring a transmission signal, accumulating synchronous data to be received, correlating the output of a filter part with accumulated synchronous data and detecting synchronism by the peak position of a correlation value. SOLUTION: The phase and the power level of the basic wave of a sub- carrier are equal to those of the output of a delay circuit 12. A power level synthesized by an adder 13 becomes twice as much as the other level. Correlation with a value which is set in a preamble buffer 15 is obtained. Thus, the power level becomes a waveform having a peak in the output of an accumulation adder 17. A judgment part 18 judges whether the power level that the accumulation adder 17 accumulates, adds and outputs is not less than a threshold level which is previously set. Thus, the transmission timing of a preamble signal is precisely detected. Consequently, synchronous timing is precisely detected based on the peak detection of the power level by detecting the preamble signal.
