    • A transmission method for use in a multi-hop wireless communication system is provided. The system includes a source apparatus, a destination apparatus and one or more intermediate apparatuses. The system has access to at least one predetermined transmission introduction sequence and also has access to a time-frequency format for use in assigning available transmission frequency bandwidth during a discrete transmission interval, said format defining a plurality of transmission windows within such an interval. Each window occupies a different part of that interval and has a frequency bandwidth profile within said available transmission frequency bandwidth over its part of that interval. Each said window being assignable for such a transmission interval to at least one of said apparatuses for use in transmission. The method includes, when transmitting a message with a preamble in a particular transmission interval, transmitting the preamble in a first transmission window of that transmission interval. Furthermore, the method includes transmitting the transmission introduction sequence in a second transmission window of that transmission interval other than the first transmission window preferably as control information for use by at least one said intermediate apparatus or the destination apparatus.
    • 提供了一种用于多跳无线通信系统的传输方法。 该系统包括源设备,目的地设备和一个或多个中间设备。 该系统可以访问至少一个预定的传输介绍序列,并且还可以访问用于在离散传输间隔期间分配可用传输频率带宽的时间 - 频率格式,所述格式在这样的间隔内定义多个传输窗口。 每个窗口占据该间隔的不同部分,并且在该间隔的部分内在所述可用传输频率带宽内具有频带配置。 每个所述窗口可分配给用于传输的所述设备中的至少一个的这种传输间隔。 该方法包括:在特定发送间隔中发送具有前导码的消息时,在该发送间隔的第一发送窗口中发送前导码。 此外,该方法包括:在第一传输窗口之外的传输间隔的第二传输窗口中优选地传输传输介绍序列作为至少一个所述中间设备或目的设备使用的控制信息。

    • The object of the invention is to ease of operation of the power impact tool. Such object is achieved by a representative power impact tool according to the invention including a motor, a tool bit, a trigger and a mode changing member. The trigger is manually operated by a user to control energization and non-energization of current to drive the motor. The motor is energized when the user operates the trigger to turn on and the energized state of the motor is maintained until the trigger is again operated in a same manner with the turning-on operation. According to the invention, once the trigger is depressed from the initial position to the operating position, a hammering operation can be performed by the striking movement of the tool bit without the need to lock the trigger in the operating position. Therefore, ease of operation of the hammer drill is enhanced.
    • 本发明的目的在于便于动力冲击工具的操作。 这样的目的是通过根据本发明的代表性动力冲击工具实现的,其包括马达,工具钻头,扳机和模式改变构件。 触发器由用户手动操作以控制电流的通电和不通电以驱动电动机。 当用户操作触发器导通并且电动机的通电状态保持直到触发器以与接通操作相同的方式操作时,电动机被通电。 根据本发明,一旦触发器从初始位置按压到操作位置,则可以通过工具钻头的打击运动来执行锤击操作,而不需要将触发器锁定在操作位置。 因此,提高了锤钻的易操作性。

    • With a recording medium causing a computer to execute a color adjustment program used for the color adjustment of a display, weights are assigned to the adjustment amounts of colors included in an adjustment range in correspondence with a positional relationship with a target color in color space, and the adjustment amount of the target color, when information about the target color to be adjusted, the adjustment amount indicating the amount of the color adjustment made to the target color, and the adjustment range for deciding the range of colors to be adjusted along with the target color are input. According to the weights, colors after the adjustment for the target color and the colors included in the adjustment range are calculated, and a three-dimensional region corresponding to the calculated colors is drawn in the color space.
