Abstract: An angle detection apparatus includes a magnetic sensing element, a magnetic field generator, and a yoke. The magnetic field generator is rotatable around a rotation axis with respect to the magnetic sensing element and generates a magnetic field. The yoke is disposed in a magnetic-field influence region and is rotatable together with the magnetic field generator. The magnetic-field influence region is a region that lies between the magnetic field generator and the magnetic sensing element in a rotation axis direction along the rotation axis, and that is to be influenced by the magnetic field.

Abstract: To correctly trace a target component even when a folded component is included in a Doppler waveform. The Doppler waveform is configured by a plurality of luminance distributions 54 arranged on a time axis. In each luminance distribution 54, a minimum luminance value located in the trough portion 54c between the target portion 54a and the folded portion 54b is specified. A search start point Pn is set based on the minimum luminance value. A trace point 60 is specified by searching from the search start point Pn to a base line 61 side.

Abstract: A computing device generates a Doppler waveform based on a signal obtained by transmitting and receiving an ultrasonic wave; applies a second-order differentiation process to the generated Doppler waveform; and identifies peak detection periods that have a polarity corresponding to a curve of a detection target peak. The polarity is of a second-order differential value obtained by the second-order differentiation process. The computing device further obtains, for each of the multiple identified peak detection periods, a peak scale based on a duration of the peak detection period and a peak value of the Doppler waveform in the peak detection period, and detects a peak in the Doppler waveform based on the peak scale corresponding to each of the multiple peak detection periods.

Abstract: A guidance image generation unit generates a guidance image in which setting position information and setting order information of each manually set representative point are marked on a schematic diagram schematically representing an organ image included in an ultrasonic image. A schema diagram schematically shows a tomographic image of the heart. A position marker is a specific example of the setting position information and a number label is a specific example of the setting order information. A plurality of position markers indicate positions corresponding to a plurality of feature points in the schema diagram schematically showing an apical three-chamber (A3C) view. A plurality of number labels indicate setting orders of the plurality of feature points.

Abstract: A centrifugally cast composite roll comprising an outer layer having a composition comprising by mass 2.5-9% of C, 0.1-3.5% of Si, 0.1-3.5% of Mn, and 11-40% of V, the balance being Fe and inevitable impurities; an intermediate layer made of a high-speed steel alloy, which is formed inside the outer layer; and an inner layer made of cast iron or steel, which is formed inside the intermediate layer.

Abstract: A graphic display processing apparatus which includes a CPU, a VRAM and a display controller, a data operation unit, an access cycle generator, an address generator and a sequential transfer sequencer. The graphic display processing apparatus also includes a mask pattern generator, dot mask generator and data position transformer. In the graphic display process apparatus block transfer and character drawing are reformed at high speeds, thereby making a window system more practical and offering comfortable operational environment to the user.
