  • Patent number: 8149367
    Abstract: An IPS-method liquid crystal display device which exhibits small directivity of a viewing angle and high brightness is realized. A planar common electrode is arranged below a pixel electrode which includes comb-teeth-shaped electrodes and slits. When a video signal is applied to the pixel electrode, an electric field is generated between the pixel electrode and the common electrode by way of slit portions formed in the pixel electrode thus controlling liquid crystal molecules. To reduce the occurrence of a phenomenon that an abnormal domain is generated in an end portion of the slit and the abnormal domain lowers transmissivity of liquid crystal, the structure in which the slits having both ends thereof closed and the slits having one-side end portion thereof opened are alternately arranged next to each other in parallel is adopted.

A transmission apparatus (eNB) transmits an instruction of CSI request distributed for each reception apparatus in a subframe concurrently with or earlier than a reference signal CSI-RS to each of reception apparatuses (UE1, UE2). Each of the reception apparatuses (UE1, UE2) detects the CSI request from the transmission apparatus and calculates CSI from a channel estimation value of CSI-RS received thereafter. Then, the reception apparatus identifies CSI report subframe of the own apparatus from CSI report interval information of a given time interval notified in advance, the subframe in which the CSI request is detected and transmission timing of CSI-RS, and transmits a feedback signal including CSI report value by using PUSCH at the timing of the CSI report subframe.

    Abstract: If a short circuit does not occur during deceleration of a wire feed speed in forward feed of a welding wire before the wire feed speed reaches a predetermined wire feed speed, a cyclic change is stopped and the wire feed speed is constantly controlled at the first feed speed. If a short circuit occurs during forward feed at the first feed speed, deceleration from the first feed speed starts, and the cyclic change is resumed for welding. This achieves uniform weld bead without increasing spatters even if any external disturbance such as change of distance between a tip and base material occurs.
