  • Patent number: 8212925
    Abstract: A sync separation circuit separates a synchronizing signal from a video signal containing the synchronizing signal. A minimum level detecting section detects a minimum level of a video signal. A sync tip level detecting section detects a sync tip level in the video signal. A pedestal level detecting section detects a pedestal level in the video signal. Based on both the sync tip level detected by the sync tip level detecting section and the pedestal level control by the pedestal level detecting section, a slice level setting section sets a slice level corresponding to an intermediate value between the sync tip level and the pedestal level. The slice level control section sets the slice level based on the minimum level detected by the minimum level detecting section if the slice level set based on the sync tip level and the pedestal level is inappropriate.

  • Patent number: 8153941
    Abstract: A first plate material is set on a work stage. The first plate material includes first components commonly connected to a first connection member. A second plate material is subsequently set on the work stage. The second plate material includes second components commonly connected to a second connection member. The second components are superposed on the corresponding first components. The first components as well as the second components can be handled as a one-piece component. It leads to an improved productivity. Heat surfaces of a heat block contact the second components. The connection members are prevented from thermal expansion. The constant intervals are reliably maintained between the adjacent first components and the adjacent second components.

  • Publication number: 20120079868
    Abstract: A transformation matrix used for finding actual loads acting on a tire can be reliably calibrated. Using the calibrated transformation matrix, the translation and moment loads exerted on the tire can be calculated with a high degree of accuracy in a multi-component force measuring spindle unit including two multi-component force measuring sensors on locations spaced-apart from each other along the axis direction of a spindle shaft. The calibration method includes a step of measuring loads exerted on the spindle shaft, a calculation step using a measured load vector including the loads obtained in the measurement step and the transformation matrix applied to the measured load vector, to find an actual load vector including actual loads on the tire. Before the calculation step, a calibration step determines the measured load vector under a plurality of linearly independent test conditions and calibrates the transformation matrix based on the determined measured load vector.
