A moving image coding method that can prevent playback discontinuity without an increase in processing load during playback is provided.The moving image coding method codes a video stream that includes a first moving image and a second moving image to be overlaid on the first moving image. The moving image coding method includes: a step of determining a continuous playback section that is a group of partial sections and is subject to continuous playback, in the video stream (S5301 to S5303); a step of coding the first and second moving images in the partial sections constituting the continuous playback section, under a constraint that prevents a threshold from being changed in the continuous playback section, the threshold being used for a transparency process by a luminance key in the overlaying (S5304); and a step of generating management information including flag information which indicates that the threshold is fixed in the continuous playback section (S5305).

A printed wiring board including solder pads excellent in frequency characteristic is provided. To do so, each solder pad 73 is formed by providing a single tin layer 74 on a conductor circuit 158 or a via 160. Therefore, a signal propagation rate can be increased, as compared with a printed wiring board of the prior art on which two metal layers are formed. In addition, due to lack of nickel layers, manufacturing cost can be decreased and electric characteristics can be enhanced.

A controller capable of preventing response delay and generation of vibrations attributable thereto during position control of a movable part of a machine having low rigidity. A motor for driving a machine having low rigidity is subjected to position and velocity loop control. Compensation amount Q1 proportional to command velocity obtained by differentiating a position command and compensation amount Q2 proportional to second-order differentiated command acceleration are obtained. Compensation amounts Q1 and Q2 are added together, thus obtaining a velocity offset amount Vof corresponding to a estimated torsion amount. A differentiated value of the velocity offset amount is multiplied by coefficient β to obtain a torque offset amount Tof. The velocity offset amount Vof is added to a velocity command Vcs obtained by position loop control 1. The torque offset amount Tof is added to a torque command Tc outputted in velocity loop control 2, and the result is used as a drive command to the motor. Based on the velocity and the torque offset amount Vof and Tof, a torsion amount between motor 3 and the machine is controlled. The machine position and velocity are controlled with accuracy by regular position and velocity loop control.

The present invention provides a storage subsystem capable of realizing efficient data migration and high access performance. During migration of data between storage subsystems, data migration methods are selected between a “PUSH” type and a “PULL” type method based on a data migration policy set in advance to perform data migration processes. An access characteristics of a file and a folder storing the file are determined based on a file access frequency or a final access date and time information in a migration source storage subsystem, and the migration order of a file group determined to have a high possibility of being accessed during data migration is changed between the “PUSH” type and the “PULL” type.

“Discharge delay” and “dependence of discharge delay on temperatures” are solved by improving a protective layer, thus a PDP can be driven at a low voltage. Furthermore, the PDP can display excellent images by suppressing “dependence of discharge delay on space charges.” Liquid-phase magnesium alkoxide (Mg (OR)2) or acetylacetone magnesium ate whose purity is 99.95% or more is prepared, and is hydrolyzed by adding a small amount of acids to the solution. Thus, a gel of magnesium hydroxide that is a magnesium oxide precursor is formed. Burning the gel in atmosphere at 700° C. or more produces powder containing MgO particles 16a-16d having the NaCl crystal structure with (100) and (111) crystal faces or with (100), (110) and (111) crystal faces. By pasting the powder on a dielectric layer 7 or a surface layer 8, the MgO powder 16 is formed so as to serve as the protective layer.

A feedforward control section computes, on the basis of a target current absolute value, a voltage limit value of a motor drive circuit, and a rotational speed ωr of a motor, a phase angle of a voltage vector which represents the output voltage of the motor drive circuit by a d-q coordinate system, the phase angle being a phase angle in relation to the d-axis of the d-q coordinate system. A feedback control section computes a phase angle based on a deviation between the target current absolute value and the actual current absolute value. A PWM control signal generation section outputs PWM control signals such that the motor drive circuit outputs a three-phase drive voltage whose electrical angle is advanced by a phase angle. Thus, in the case where a large reverse input is applied to a steering mechanism, the motor is caused to generate a large torque to thereby prevent the steering wheel from being rotated.

A vehicle operation assist system includes as assist yaw rate calculator which calculates a necessary moving amount to avoid an obstacle based on a detection result of the obstacle by a radar device, and a vehicle movement controller controls lateral movement of the vehicle based on the calculated moving amount. When an avoiding operation detector determines initiation of an obstacle avoiding operation by the driver, the vehicle movement controller operates a braking device to control the lateral movement of the vehicle, so that the obstacle can be reliably avoided. When a restoring operation detector determines initiation of a restoring operation, the vehicle movement controller operates a power steering device to control the lateral movement of the vehicle, so that delay in the steering operation by the driver, and excessive restoring operation of the steering handle to compensate for the delay are suppressed, thus stabilizing vehicle behavior.

The present method adds uplink data to a transmission request sent to the base station from the mobile station for obtaining permission for data transmission, or to a channel establishment request sent from the mobile station to the base station for establishing a channel in order to send the transmission request therethrough. This makes it possible to suppress delay caused by negotiation prior to actual uplink data transmission as much as possible, thereby realizing efficient uplink data transmission, that is, improved throughput of uplink communication.

A scheduling method for transmitting an uplink signal from a mobile station to a base station comprises transmitting the uplink signal in a first scheduling mode in which the mobile station can transmit the uplink data without permission of the base station if an uplink communication state between the base station and the mobile station is higher than or equal to a predetermined quality; and transmitting the uplink signal in a second scheduling mode in which the permission is necessary for the mobile station transmitting the uplink data if the uplink communication state is lower than the predetermined quality.

A light-emitting device having the quality of an image high in homogeneity is provided. A printed wiring board (second substrate) (107) is provided facing a substrate (first substrate) (101) that has a luminous element (102) formed thereon. A PWB side wiring (second group of wirings) (110) on the printed wiring board (107) is electrically connected to element side wirings (first group of wirings) (103, 104) by anisotropic conductive films (105a, 105b).

Accordingly, the homogeneity of the quality of an image is improved, and the operating speed of a driver circuit portion is enhanced.
