Title: Adaptive equalization device
Inventor: KATSUMATA NORIAKI
IPC: H03H21/00
Filed: 2001-09-19
Abstract: PROBLEM TO BE SOLVED: To realize an estimation part of an adaptive equalization device with a simple configuration. SOLUTION: A control circuit 50 performs learning for controlling a coefficient of a filter 30 so as to eliminate an error ei between a learning pattern di from a blind estimating part 60 for directly demodulating a reception signal and an output yi of an adaptive equalizer from a variable filter 30 for equalizing the reception signal. The output yi of the adaptive equalizer is outputted with data obtained in such a manner that an identification decision circuit 40 identifies and decides 1 and 0 as a modulated waveform. An equalized waveform monitoring circuit 70 monitors an equalized waveform yi, outputs the equalized waveform yi as a tracking mode to a switching part 102 when the equalized waveform yi reaches set equalized quality, and learns a demodulated waveform from the identification decision circuit 40 as a learning pattern di in the tracking mode.  Since the bland estimating part 60 directly demodulates the reception signal, the bland estimating part 60 can configure a simple algorithm and flexibly correspond even to change of modulation methods.

Title: Apparatus for discharging capacitive load variable element
Inventor: NAGASE NOBORU
IPC: F02D41/20
Filed: 2001-09-19
Abstract: PROBLEM TO BE SOLVED: To solve the problem that, since the capacity of a piezoelectric element is temperature-changed, a discharging energy does not become constant by a conventional discharging method, and hence a discharging time is changed, and since the discharge is stopped by a time guard at the last of discharging, the discharging is finished at an improper timing so that the piezoelectric element cannot be completely discharged. SOLUTION: A breaking current for turning OFF a discharge switch 42 is raised as a time goes. Since the discharging time is reduced as the capacity of the piezoelectric element 1 is discharged, but since the breaking current is increased, a discharge energy of their product becomes constant. As a result, even when the capacity of the element 1 is changed, the discharge energy is maintained constantly. Since the switch 42 is turned OFF when the load voltage of the element 1 is lowered to 0 V, the switch 42 can be turned OFF at the optimum timing, and hence the element 1 can be substantially completely discharged.
