Title: Ultrasonic photographic method and ultrasonic photographic apparatus
Inventor: SATO TOMOO
IPC: G01N29/06
Filed: 2001-02-26
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic photographic method and ultrasonic photographic apparatus whose capability of gaining image information of high frame rates or image resolution is improved by increasing the number of ultrasonic beams to be transmitted within a given unit time. SOLUTION: In this photographic method, an image up to a visible depth in the neighborhood of the heart is preliminarily take before the respective tomographic sections to be displayed on a display unit are marked by a device for setting a measurement range covering the existence of the heart. The existence range M of a marked tomographic image HB is then surveilled, where a scanning process of transmitting an ultrasonic pulse that forms the next ultrasonic beam OB1 is proceeded at a time when the ultrasonic pulse that forms an initial ultrasonic beam OB0 reaches the maximum depth M0 of the existence range M, thereby skipping the reception of echos from the maximum depth of the existence range M onward.  A scanning time of an entire tomographic image can be reduced when such a skipping scan in respect of a fan-shaped two-dimensional area OBB is repeated at regular intervals toward a direction of an angle θ.

The time when the brake signal is to be outputted is set based on a time when the kick signal is outputted. Then, a focusing servo 21 is turned ON when the peak of the focus error signal arrives after the outputting of the brake signal is stopped.

Title: Active filter for reducing common-mode current
Inventor: PELLY BRIAN R
IPC: H02M5/458
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce a common-mode current in an earthing conductor of a PWM-controlled motor-driving circuit. SOLUTION: There is used an active filter containing a buffer amplifier that branches the common-mode current from the earthing conductor by linear- driving two junction-type transistors or a MOSFET transistor through the transistor. The transistor is connected between a positive and negative DC bus that feeds a DC voltage to a PWM inverter to drive an AC motor, and the AC motor generates a common-mode earthing current in the earthed frame. A current transformer monitors the common-mode current of which the output is connected to an input of the buffer amplifier to control the transistor. An internal power source for the amplifier is formed at a node that is positioned between two current sources and two Zener diodes connected between the DC bus conductors.  A headroom-voltage control circuit establishes a sufficient headroom voltage for each transistor under any condition of an AC voltage input.
