A bearing device of embodiment is usable for a hydraulic machine having a rotary shaft of a vertical shaft, with a water tank storing lubrication water, and a bearing pad supporting a skirt member on the rotary shaft in the lubrication water. The bearing device has a first supporting mechanism slidably supporting the bearing pad from the radial direction, and a second supporting mechanism slidably supporting the bearing pad from a bottom portion side in an axial direction. One of a supporting surface supporting the bearing pad in the first supporting mechanism and a supported surface supported by the supporting surface in the bearing pad is formed in a convex shape. One of a supporting surface supporting the bearing pad in the second supporting mechanism and a supported surface supported by the supporting surface in the bearing pad is formed in a convex shape.

A video signal processing apparatus comprises an A/D converter for digitizing an analog video signal, an integration circuit for integrating the digitized video signal within a predetermined integration range, a picture display device for displaying a picture based on an integration output, and a control unit which, when an offset adjustment signal is inputted to the A/D converter, corrects the offset value so as to eliminate a difference between the integration value of the integration circuit and a preliminarily set specified value, and determines whether or not offset adjustment is completed based on the number of times when the corrected offset value is within a range defined by adding a predetermined error to the specified value.

Video signal processing apparatus and video signal processing method

When a sub-image (A) and a sub-image (B) are displayed as semi-moving pictures on a multi-screen, the fields of the input sub-images (A) and (B) are determined. By setting the field determination result as one condition for a write to the memory the sub-images (A) and (B) can be stably written to the memory in either odd fields (ODD) or even fields (EVEN), and can be read and displayed on the screen without flickering characters due to line flicker. Furthermore, when video signals are switched for a channel switch or an input switch, the operation remote controller can issue a switch instruction so that a write to the video memory is stopped according to the generated switch signal, and the image is displayed as a still image. In response to a new input video signal, the number of write increase lines or picture elements for a write to the video memory is set to n. The writing operation is performed m times (m is a natural number) for every other field. According to the operation of n&times;m, the number of write increase lines or picture elements is incremented, and the updated image at the image switch can be gradually switched from one end of the screen or in combination of vertical and horizontal directions.
