  • Patent number: 5947234
    Abstract: To reduce brake noise sufficiently, a vehicle disc brake of the present invention includes a pair of pads for supporting a disc rotor therebetween, with each pad being provided with a backing plate. A mounting member which is adapted to be secured to the vehicle is designed to receive brake torque applied to the pads. Two end surfaces of the backing plate, which are opposed substantially in the turning direction of the disc rotor, are provided with a pair of projections. The projections elastically abut on first brake torque receiving surfaces of the mounting member. The backing plate has also an end surface that is supported by second brake torque receiving surfaces of the mounting member. The first and second brake torque receiving surfaces are located towards the radially outward and inward sides of the disc rotor respectively, with respect to a center of gravity of the backing plate.

  • Patent number: 5090412
    Abstract: The present invention for realizing an ultrasonic diagnosis apparatus for displaying a high-quality image having a smaller amount of speckle noise is characterized in that receiving signals of a plurality of sound rays each having a different directionality within a range of bearing resolution of an ultrasonic beam are subjected to correlation processing to determine a receiving signal for the portion of one sound ray, and an image is formed on the basis of receiving signals thus determined, thereby eliminating speckle noise. Correlation processing in its simplest form may be addition averaging processing.

  • Patent number: 5058176
    Abstract: The image diagnosis apparatus of the present invention is equipped with means for automatically determining a window level and a window width for image displaying in accordance with the value of reconstructed image data. With this window level/window width calculating means (13), the window level is obtained with respect to each reconstructed image on the basis of the virtual average value of its pixel data and the window width is also obtained which has a certain relationship with that window level. When displaying each reconstructed image, a display is made in accordance with each window level and each window width thus obtained. Instead of the obtained window level and window width, those set by a manual setting section (23) may be used by a changeover operation when necessary.

  • Patent number: 4954780
    Abstract: A scan controller for an NMR imaging device, wherein the scan controller stores control signal waveforms in a waveform memory; stores control signal amplitudes in an amplitude memory; stores data related to the control signal duration in a time memory; reads the waveform memory by using an address counter which operates based on data read out from the time memory and outputs the waveform memory read out value after conversion to analog. The amplitude of the control signal is multiplied by the waveform of the control signal and converted from digital data to analog so that the resulting amplitude is related to the amplitude of the signal stored in the amplitude memory. In this manner high amplitude resolution is attained and requirement for large scale memory capacity is reduced.

  • Patent number: 4713616
    Abstract: An NMR imaging apparatus, wherein a 180.degree. RF pulse is applied shortly after the termination of the 90.degree. RF pulse, and wherein after such 180.degree. pulse application, to collection of spins and after collection of spins to dispersion of spins are sampled asymmetrically, whereby Fourier transformation takes place by interpolating missing data on a Fourier plane, and by operating on the data, image is accurately reconstructed. The novel pulse sequence improves the S/N ratio and reduces deterioration of images.

  • Patent number: 4700138
    Abstract: In measuring a number of echo signal, which normally attenuate chronologically, in a single pulse sequence, such as in multi-echo method or a multi-slice method, each echo signal is received and suitably amplified by a reception amplifier having predetermined levels of gain for different time periods during which the successive echo signals are processed such that the echo signals received at a data collection unit are all of substantially the same amplitude regardless of where they appear in the time sequence. The predetermined levels of gains are obtained by false scanning prior to actual image scanning and calculation and storing in a memory. As a result, the echo signals can be received within a dynamic range which is smaller than using the conventional system.

  • Patent number: 4631710
    Abstract: In ultrasonic transmission from and reception by an array probe in a phased array sonar, when an ultrasonic beam is directed substantially in front of the array probe, an ultrasonic wave having a high center frequency f.sub.o, or a bandwidth extending into higher frequencies, is transmitted and/or received in order to insure a high image resolution. When the ultrasonic beam is steered sideways, an ultrasonic wave having a lower center frequency f.sub.o, or a higher frequency range cutoff in relation to a steering angle .theta., is transmitted and/or received in order to increase the angle at which grating lobes are generated and hence prevent such grating lobes from entering the angle range of the field of view.

  • Patent number: 4319489
    Abstract: An ultrasonic diagnostic method and apparatus are provided for probing the condition in a tissue of a living body by projecting an ultrasonic beam onto the living body from a vibrator array transducer probe consisting of a plurality of tiny ultrasonic vibrators. The apparatus executes two scanning actions, of which one is a normal linear scanning that drives the ultrasonic vibrators sequentially in the manner to cause a sequential parallel shift of the ultrasonic beam substantially perpendicular to the vibrator array, and the other of which is an inclined linear scanning that drives the ultrasonic vibrators at individually different timings while sequentially shifting the driven vibrators in the manner to cause sequential parallel shift of the ultrasonic beam having an angle of inclination against the vibrator array. The images obtained through the normal linear scanning and the inclined linear scanning are combined to form a composite high-resolution image.
