  • Publication number: 20240297061
    Abstract: A substrate processing apparatus includes a vacuum container, a rotary table, a stage, a lifter, and a controller that controls an operation of the lifter. The controller automatically sets a control position in the operation of the lifter. The controller, in (A), repeatedly raises the lifter by a first pitch and then determines whether or not the lifter has come into contact with a substrate, thereby bring the lifter to come into contact with the substrate to set a next position. The controller, in (B), repeatedly raises the lifter from the next position by a second pitch shorter than the first pitch and then determines whether or not the lifter has come into contact with the substrate, thereby detecting a touch position and calculating the control position based on the touch position.

  • Patent number: 7035612
    Abstract: An antenna diversity communications device switches communications paths between a plurality of antennas to improve reception in a frequency diversity communications system. Antenna selection is done in response to measurement of the receiving condition of the selected antenna. A memory unit stores frequency difference information between the current channel and the next channel. When the frequency difference between the current channel and the next channel is small enough to predict good correlation between the channels, and if current receiving conditions are good, the current channel remains connected. When the frequency difference between the current channel and the next channel is large enough to predict poor correlation, or if the receiving conditions on the current channel are bad, one of the other channels is selected.

  • Publication number: 20050190725
    Abstract: Reception level frequency distribution is determined. A frequency correlation bandwidth is determined in accordance with intervals between peaks or dips, or alternatively intervals between intersections wherein the reception level frequency distribution intersects a threshold. At the time of reception start, a training mode period is set up to determine a frequency correlation bandwidth. After the training mode period, signals are received in accordance with the determined frequency correlation bandwidth. The frequency correlation bandwidth is determined with increased precision to avoid a large amount of calculation such as Fourier transform. As a result, the entire diversity reception processing requires a reduced amount of calculation.
