摘要:
An optimum path storage unit stores optimum paths on all wireless communication devices that can be destinations of data. A reception unit receives relay data as a relay target. A QoS judgment unit reads out an optimum path corresponding to a QoS requirement of relay data from the optimum path storage unit and judges whether or not the QoS requirement of data is satisfied by the optimum path. The QoS judgment unit outputs relay data to a transmission unit when it is determined that the QoS requirement is satisfied. The transmission unit transmits the relay data to the next node on the optimum path. When the QoS requirement of the relay data is not satisfied by the optimum path, a NACK information generation unit generates NACK information that includes the fact that transmission of the relay data has been interrupted and transmits the NACK information to neighboring wireless communication devices.

A mobile communication system using an adaptive multiantenna realizes improvement of reception characteristics, effective use of the band, and optimization of the throughput in comparison with a system in which application of the same multiantenna communication method is continued irrespective of a variation of the number of radio relay stations. The mobile communication system comprises a radio base station, a radio relay station, and mobile terminal stations for communicating with the radio base station through a radio relay station. The radio base station has a multiantenna and is characterized in that the radio base station judges if there is any variation of the number of radio relay stations when the radio base station carries out transmission through a radio relay station, and the radio base station communicates with the mobile terminal station by switching the multiantenna communication method using the multiantenna depending on the delay time of the feedback signal from the mobile terminal station if there is a variation of the number of radio relay stations.

A print control device includes a generating unit configured to generate image data, based on gloss control plane data for specifying a type of a surface effect to be given to a recording medium and specifying a region to which the surface effect is to be given in the recording medium; and an output unit configured to output the image data. The generating unit includes a tone correcting unit configured to perform a tone correction on a region in which the surface effect is designated in the gloss control plane data, the tone correction varying with each type of surface effect.

A pallet exchanger capable of providing a sufficient operation space on an operator's access side, for example, in front of a machining space, without increasing the size of the exchanger is provided.An arm 14 is formed in a chevron shape in a plane view including two forks as pallet supporting parts 14a and 14b, which are arranged radially from a turning spindle with less than 180° angle between them such as 120°. Further, by means of a table 12, the arm 14 is slidable between a stand-by position in front of a machining space and a retreating position in front of a tool magazine 8 which is adjacently provided to a machine tool 1. By moving of the arm 14 on the retreating position side, an operation space S can be provided in front of the machining space.

A microphone unit is provided to minimize the attenuation levels of received sound information, which differs depending upon the distance between the positions of microphones and a sound source. A sound source direction identification system is provided to identify the sound source direction. In addition, a moving head control system is provided, where the moving head control system includes a microphone system for receiving sound from a sound source, a sound source direction identification section for identifying the direction of the sound source by obtaining received sound information, a motor control section for generating an appropriate control command to a head moving motor, and a head moving motor for receiving the control command from the motor control section and moving or rotating a robot head in a direction according to the command.

A clamp device is provided that can prevent a table from being tilted at the time of clamping, can suppress a displacement in an axial direction at the time of clamping to a minimum, and also can be suitably used for a table unit with its table swiveling at a high speed. A table 2 has fixedly attached thereto a braking plate 7 swiveling with the table 2. A frame 3 has fixedly attached thereto fixing plates 6, 6 having inner flange portions protruding to a swiveling axis side of the table 2 with a predetermined pitch so that the inner flange portions interpose the braking plate 7. Moreover, a hydraulic cylinder 4 having a clamp piston 5 freely movable between a clamp position at which the braking plate 7 is clamped and an unclamp position at which the clamp state is released is provided with the flame 3.

A semiconductor device is fabricating using a photoresist mask pattern, and selectively removing portions of a liner nitride layer in a cell region and a peripheral circuit region. A modified FinFET is formed to reduce the influence of signals transmitted by adjacent gate lines in a cell region. A double FinFET and a substantially planar MOSFET are formed in a core region and in a peripheral region, respectively, concurrently with the formation of the modified FinFET.

In a machine tool, a support member to which a headstock is mounted movably in an upward-downward direction is movable so as to change a position thereof in a horizontal direction relative to that of a bed. A guide member is provided on the bed and configured to guide the support member. An engageable portion at which the support member is supported by the guide member is located in the support member at a level within a range of upward-downward movement of the headstock along the support member.

A method of forming a fine pattern of a semiconductor device uses a double patterning technique. A first mask pattern is formed on a first hard mask layer disposed on a substrate. A conformal buffer layer is formed over the first mask pattern. A second mask pattern is formed such that segments of the buffer layer are interposed between the first and second mask patterns, and each topographical feature of the second mask pattern is disposed between two adjacent ones of each respective pair of topographical features of the first mask pattern. A first hard mask pattern is formed by etching the first hard mask layer using the first mask pattern, the second mask pattern, and/or the buffer layer as an etch mask. A trench is formed by etching the substrate using the first hard mask pattern as an etch mask. An isolation layer, of a material that is different from that of first hard mask pattern, is formed in the trench.
