摘要:
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.

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.

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.

A pattern inspection method in which an image can be detected without an image detection error caused by an adverse effect to be given by such factors as ions implanted in a wafer, pattern connection/non-connection, and pattern edge formation. A digital image of an object substrate is attained through microscopic observation thereof, the attained digital image is examined to detect defects, while masking a region pre-registered in terms of coordinates, or while masking a pattern meeting a pre-registered pattern, and an image of each of the defects thus detected is displayed. Further, each of the defects detected using the digital image attained through microscopic observation is checked to determine whether its feature meets a pre-registered feature or not. Defects having a feature that meets the pre-registered feature are so displayed that they can be turned on/off, or they are so displayed as to be distinguishable from the other defects.

An operation assisting system enhances the operator's willingness to participate in energy-saving efforts. The operation assisting system stores information about the actual operation of operated equipment carried out by the operator, evaluates the stored operation information, and displays the results of evaluation. The evaluation results relate to the cost concerning the operated equipment, the cost of supplying energy to the operation target facility, the cost concerning the operated equipment, the amount of emission of carbon dioxide, nitride oxide, and global warming substances, the amount of primary energy consumption, the crude oil-converted amount of energy consumption, the amount of excess or shortage of supply of energy, or electric power quality.
