摘要:
A base station apparatus includes a scheduler configured to schedule assignment of radio resources based on a scheduling coefficient for one or more user equipments, a control signal generation unit configured to generate a control signal including reporting indication information for indicating whether the user equipment is to report downlink channel state information and scheduling grant information for indicating the scheduled assignment of the radio resources and a transmitting unit configured to transmit the control signal in a downlink. A cumulative value is calculated for each of the user equipments. The reporting indication information transmitted to a user equipment, whose cumulative value reaches a predefined value, indicates that the user equipment is to report the downlink channel state information. The cumulative value is updated if the scheduling coefficient satisfies a predefined condition.

Embodiments of the present invention prevent a magnetic disk drive from increasing in size and in manufacturing cost and reduces a positioning error of a magnetic head. An embodiment of a magnetic disk drive in accordance with the present invention includes: a disk-shaped magnetic disk that is rotated and driven; a magnetic head that reads and writes information to and from the magnetic disk, an arm that supports and moves the magnetic head; a spoiler that is close to a disk surface and extends in a radial direction of the disk; and a cabinet that houses these parts. The spoiler is disposed closer to an upstream side in a rotational direction of the disk than the arm and has a flow rate suppressing clearance positioned in a central portion in a peripheral direction of the spoiler, opened to both sides in an axial direction, and formed in a shape elongated in a radial direction of the disk.

When a closed loop transmission diversity control is performed by controlling the phase of the transmission signals from the plurality of antennas according to feedback information noticed by the mobile station to transmit the signals, an antenna verification on-off control unit 370 controls the on-off of an antenna verification process of estimating the phase of the transmission signals from the plurality of antennas according to the information about the channel of the signals transmitted in the uplink from the mobile station to a radio base station. Thus, depending on the channel type (for example, a packet channel, a voice channel, etc.), the on-off control is performed on the antenna verification process, thereby performing easier and more appropriate control and improving the quality of a channel.

A mobile station (100) according to the present invention includes: a transmitter unit (110) configured to transmit an uplink shared signal at a first time interval based on a received first downlink control signal; and a retransmitter unit (110) configured to retransmit the uplink shared signal at a second time interval based on a second downlink control signal received at a third time interval allocated fixedly. When the third time interval overlaps a time interval for measurement by the mobile station (100), the transmitter unit (110) is configured to transmit the uplink shared signal at the first time interval and the retransmitter unit (110) is configured not to retransmit the uplink shared signal at the second time interval.

A resin composition (2) such as a photo-curable resin composition or a heat curable or thermosetting resin composition is placed on an optical substrate (1). A printing pressure is applied to the side of the resin composition (2) of the optical substrate (1) with the resin composition (2) by means of an extra-flat pressing plate having a flatter plane than the optical substrate (1). The resin composition is cured by utilizing light or a temperature change to form a composite substrate. A thin film (4) such as a functional inorganic optical film, a dielectric multilayered optical thin film, or an optical functional metallic film is stacked on the composite substrate, for example, by low-temperature sputtering or ion beam sputtering to form an optical component such as a reflection mirror, a beam splitter, a band-pass filter, a band-stop filter, and an edge filter.

An objective is to provide a motor stator that may achieve: a reduction in parts costs by shaping coil ends so that length thereof is reduced, thereby reducing the amount of use of copper, and minimizing the amount of use of binding strings for securing the coil ends in place; a reduction in manufacturing process costs by a structure which allows a protector and a wire lead outlet part to be easily assembled; and then an improvement in quality of a stator by firmly holding the coil ends and the protector. The motor stator may include a stator core 1 including slots; a plurality of cut surfaces forming flat surfaces on the outer surface of the stator core 1; end surface insulating plates 2 formed in an approximately same shape as the shape of magnetic steel plates punched out, and assembled into the stator core 1 on both axial end surfaces thereof; projections formed in a vicinity of a peripheral portion of an end surface insulating plate 2, and engaged with the cut surfaces on the stator core 1; slot-like cutouts, a little larger in size than the slots, formed on an inner peripheral side of the each end surface insulating plate 1; and coil ends. The coil ends are shaped by pressure against the end surface insulating plates 2.
