Patent application numberDescriptionPublished
20100195569COMMUNICATION TERMINAL DEVICE AND COMMUNICATION METHOD - Provided is a communication terminal device that reduces, in a network using a power line, the percentage of bands consumed for transmission of control packets in the bands consumed for all the communication, so as to ensure transmission of data intended to be transmitted. A PLC terminal F08-05-2010
20100195656COMMUNICATION APPARATUS AND COMMUNICATION METHOD - There is provided a communication apparatus which, in an ad-hoc network, when receiving control packets from a plurality of terminals, can determine whether or not there is a collision among the control packets, and, based on the determination, can be prevented from continuing to be out of the network due to a collision among the control packets transmitted from the plurality of terminals. In the communication terminal, a communication section receives a control packet which periodically comes up on a communication path. When the communication apparatus receives a plurality of control packets which are defective in at least payload portions thereof within a predetermined time period, if a control section determines that source addresses included in header portions of the control packets which are defective in the payload portions thereof include a source address which is not identical to the other source addresses, the control section determines that the control packets are transmitted from a plurality of terminals and collide with each other.08-05-2010
20100227495RESIN MOLDED PARTS WITH LOCK ARM, CONNECTOR USING IT AND METHOD FOR FORMING RESIN MOLDED PARTS WITH LOCK ARM - In resin molded parts with lock arms, a peripheral wall 09-09-2010
20100248528LIF CONNECTOR - A connector comprising a first connector provided with a first projection and a second projection on an outer surface thereof; and a frame including a wall portion defining an opening, the wall portion provided with a first guide running in a direction and a second guide on an inner surface thereof, wherein the first connector is inserted into the frame through the opening along the direction while the first projection is guided by the first guide and the second projection is guided by the second guide, and at least a part of a distance between the first guide and the second guide shortens along the direction.09-30-2010
20100270074MOLD STRUCTURE FOR MOLDING HOUSING, METHOD FOR MOLDING HOUSING, AND HOUSING - A mold for forming a housing having a lance includes a first mold and a second mold. The lance has a first projection for engaging a terminal and a second projection provided at a position nearer with an end of the lance than the first projection. The first mold includes a first member having a third projection. The second mold includes a second member and a third member. The second member has a first concave portion into which the third projection is inserted. The third member is configured to be moved with respect to the second member. The second member defines, with the first member, a first space where the housing is adapted to be formed. The third member defines, with the first member, a second space where the first projection and the second projection are adapted to be formed.10-28-2010
20100290393COMMUNICATION TERMINAL AND COMMUNICATION METHOD - Provided is a communication terminal that is capable of securing a route having the finest state while suppressing a bandwidth that is consume by a transmission of a control packet at a low level, when applied in an ad-hoc network which uses an electrical power line. The communication terminal included in the ad-hoc network acquires a plurality of route candidates at the beginning of a data transmission by conducting a broadcast transmission of a route creation packet, and acquires a route having the finest state by conducting an unicast transmission of a route estimation packet to each of the route candidates in each predetermined period.11-18-2010
20110261706COMMUNICATION APPARATUS AND COMMUNICATION METHOD - A source apparatus writes, in a route request packet, the number of routes requested by the source apparatus. When a relay apparatus receives a route request packet for the first time, the relay apparatus determines a waiting time period, based on a route evaluation value that indicates a state of a route through which the route request packet has passed, and starts a timer. The relay apparatus selects route request packets having as high route evaluation values as possible, among route request packets that have been received until the timer expires, the number of route request packets to be selected being equal to the number of routes requested by the source apparatus, and then broadcasts the selected route request packets.10-27-2011
