    摘要： In an address driving system for driving address electrodes of a display panel, GND for VCC is newly provided between an address driving board and an address bus board to organize two systems of GNDs (for VCC and for VH). Furthermore, in the GND for VCC, an impedance is applied onto a GND line between a connection point of the GND for VCC mounted on the address bus board and a point at which the GNDs are unified together. This impedance is assumed to be larger than an impedance of a parasitic inductance at a connection point of the GND for VCC of a VCC power supply smoothing capacitor on an address driving board side.

    摘要： In a plasma display module, a flexible substrate is strengthened and a mounting structure for alleviating stresses is provided, thereby preventing the metal fatigue of wirings. In a PDP (Plasma Display Panel) module, a metal plate and a flexible substrate constituting a driver module are provided. On the flexible substrate, wirings not connected to electrodes of the panel (independent linear patterns) are disposed on an outer side of wirings and near an edge portion of the metal plate to which the flexible substrate is attached.

    摘要： An ultrasonic continuous wave blood flowmeter using Doppler effect analysis includes a filter having a cut-off frequency determined in part by a manually selected zero shift value. A tranducing device, in the flowmeter includes a transmission element and a reception element, the transmission element transducing an electric transmission signal into an ultrasonic signal to irradiate a living body and the reception element transducing a reflected ultrasonic signal into an electric reception signal. A detecting circuit is operatively connected to the transducing device for orthogonally detecting the electric reception signal and outputting a Doppler detection signal. A filter circuit is operatively connected to the detecting circuit for cutting high frequency components of the Doppler detection signal based on the cut-off frequency and outputting an analog signal. A converting circuit is operatively connected to the filter circuit for converting the analog signal of the filter circuit to a digital signal based on a Doppler sampling frequency having a continuous wave. A transforming circuit is operatively connected to the converting circuit for analyzing the digital signal and obtaining a Doppler frequency spectrum based on a Fourier transform method. A control circuit is operatively connected to the filter circuit for controlling the cut-off frequency based on the Doppler sampling frequency and the zero shift value.
