摘要:
A semiconductor substrate cleaning apparatus and method are capable of efficiently removing contamination from both the obverse and reverse sides of a semiconductor substrate. A single cleaning liquid supply nozzle for supplying a cleaning liquid to both the obverse and reverse sides of a semiconductor substrate to be cleaned is placed at a distance from the outer peripheral edge of the substrate. An ultrasonic vibrator applies ultrasonic waves to both the obverse and reverse sides of the substrate. Four driving rollers are disposed in contact with the outer peripheral edge of the substrate. The driving rollers are adapte to rotate while being engaged with the outer peripheral edge of the substrate thereby drivingly rotating the substrate.

The present invention relates to a substrate processing apparatus and a substrate processing method for performing a chemical liquid process, a cleaning process, a drying process, or the like while rotating a substrate such as a semiconductor wafer or a liquid crystal substrate. The present invention also relates to a substrate holding apparatus for holding and rotating a substrate. The substrate processing apparatus (1) for processing a substrate (W) while supplying a fluid to the substrate (W) includes a substrate holder (11) for holding and rotating the substrate (W), and a holder suction unit (24) for sucking the fluid from the substrate holder (11). The substrate holding apparatus includes a plurality of rollers (20) which are brought into contact with an edge portion of a substrate (W) so as to hold and rotate the substrate (W), and at least one moving mechanism (303a) for moving the rollers (20).

The present invention is designed to reduce the space to install antennas and still increase the system capacity despite the state of the distribution of user terminals in cells. According to the radio communication method of the present invention, a radio base station apparatus selects precoding vectors from a codebook that is set in advance to be uneven with respect to the direction of the arrangement of antenna elements, based on communication quality information of the user terminals in the cell, multiplies signals to supply to each antenna element by the selected precoding vectors, and transmits the signals multiplied by the precoding vectors to the user terminals, and the user terminal receives a signal from the radio base station apparatus, extracts a reference signal from the received signal and measures channel quality; and feeds back a communication quality feedback signal, including the measured channel quality, to the radio base station apparatus, via the uplink.

An electrical charging apparatus includes: an electrical charging control ECU that makes a determination about motion of a hybrid vehicle; and a charging-purpose plug which engages with the hybrid vehicle if the amount of movement of the vehicle is less than a predetermined value, and which releases the engagement with the hybrid vehicle if the amount of movement of the vehicle is greater than or equal to the predetermined value. According to the invention, even if the vehicle moves while being charged, the dragging of the charging cable is prevented.

An image signal display device includes program data readout circuitry by which at least one second adjustment data not to be adjusted takes a proper value relative to a first adjustment data to be adjusted, in accordance with a predetermined relational expression. Data calculating circuitry is provided to calculate the second adjustment data in accordance with the predetermined relational expression, in response to a change in the first adjustment data. Data changing circuitry is provided to change the second adjustment data together with the first adjustment data. A memory is provided to store at least a coefficient data of the relational expression, wherein the memory can be read out from and written to. A digital/analog conversion circuit is provided to convert an output signal from the memory into an analog signal. Additionally, a display is provided to represent an output signal from the digital/analog conversion circuit as an image.
