Abstract: A laser beam direct imaging apparatus and an imaging method which can precisely determine a back-surface-side position with respect to a front-surface-side position even if any kind of photosensitive material is used. In the laser direct imaging apparatus, a laser beam is deflected toward a main scanning direction (X-axis direction) while a workpiece mounted on a table is moved in a sub-scanning direction (Y-axis direction) so that a pattern is imaged on the surface of the workpiece. Hollow pins are disposed on the table so that the tips of the hollow pins 20 project over the surface of the table by a predetermined distance. The workpiece is sucked onto the table so that indentations (indentations by the tips of the hollow pins) are formed on the back surface of the workpiece. When a pattern is imaged on the back surface, imaging is performed with reference to the indentations.

Abstract: The present invention eliminates a transmission-waiting operation which is unnecessary while accommodating a prioritized traffic. Although a communication station enters a transmission-disallowed state in response to detection of a signal addressed to another station in accordance with medium access control based on CSMA, if the communication station receives a frame transmitted with priority to a local station during the transmission waiting, it cancels the transmission-disallowed state, sends back a frame responding the frame transmitted with priority and effectively operates a transmission prioritized period. The communication station starts a search procedure to perform a processing of evading duplication of the transmission prioritized periods if it judges a possibility of a problem occurring in a time zone in which reception with priority is possible.

Abstract: Multi-carrier transmission is performed without inserting a repetitive signal into guard interval periods. A transmitter provides guard interval periods by using a null signal to save transmission power and prevent the deterioration of the SN ratio. Delayed waves at the head of each received symbol cause high-frequency waves to occur and carriers to interfere with one another. Accordingly, a receiver adds a component following each received symbol to a delayed-wave component at the head of the received symbol. As a result, the delayed-wave component at the head of the received symbol and the added component become continuous in wave form and subcarriers do not interfere with each other.

Abstract: A communication terminal under the control of a wireless base station recursively has wireless base station capabilities in a parent network, constructs a daughter network within a scope of resources of the own apparatus assigned by the wireless base station, and assigns the resources to an other communication terminal under the control of the communication terminal having base station capabilities. This novel constitution allows to configure two or more networks guaranteed not to interfere each other, thereby allowing the coexistence of a plurality of personal area networks on a same frequency channel. At the same time, the novel constitution allows expanding a network area without increasing the scale of equipment.

Abstract: There is provided a communication apparatus compliant with ultra wide band communication systems for improving resistance to interfering waves in combination with DS-SS (direct sequence spread spectrum). There is provided a training section based on short code spread with the same pattern repeated for each symbol length. Actual communication itself is preceded by coherent channel measurement of a transmission channel by using the training section to specify a length of the short code to be a measurement period and using N cycles of a carrier as a time resolution for measurement. A chip timing is controlled at the time resolution for measurement. At all points given by a time resolution for a measurement period, a measured value is obtained by using the short code to despread A/D-converted values from an input signal based on the chip timing.
