Filed: 2011-03-31
Abstract: PROBLEM TO BE SOLVED: To collect meter reading data at low costs, in a short time, and with high reliability in a system in which a plurality of meter terminals transmit meter reading data to an aggregation device by multi-hop radio communication.SOLUTION: When data are simply transmitted in order from a terminal whose number of hops is large as seen in (a) in order to secure a retransmission time within a communication validating time of 120 seconds, the deviation of traffic per time is increased between the first half (0 to 60 seconds) and the second half (60 to 120 seconds). In (b), an assigned communication time is specified from the distribution of the number of terminals with respect to the number of hops before (a). While the deviation of the traffic is reduced, a peak is still large (concentrating in 60 to 100 seconds). In (c), a random standby time is added in addition to (b). Thus, it is possible to largely reduce the peak.

Title: Game machine
Inventor: MATSUSHITA SHINSUKE
IPC: A63F7/02
Filed: 2011-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a technique for suppressing the lowering of motivation for continuing a game even when the lottery of a first stage has to be performed again since the lottery of a second stage is not cleared.SOLUTION: The first stage lottery is the lottery related to whether advance can be performed to the succeeding second stage lottery. The succeeding second stage lottery is the lottery having no pure loss and relating to whether a shift to a first time shortening state (chance zone) is substantially performed, and thereby having a higher added value. When the entry to the first time shortening state is won in the second stage lottery, the entry to the first time shortening state is performed, and thereby providing expectations for profit continuity. Alternatively, even when the entry to the first time shortening state is not won in the second stage lottery, room for shift to a second time shortening state (special symbol: low/high probability and variable time shortening, and normal symbol: time non-shortening state), by which entry is easily performed to the first time shortening state, is left, and thereby suppressing the lowering of motivation for continuing a game.

Title: Power circuit
Inventor: NOMURA KOSAKU
IPC: H02M7/12
Filed: 2011-04-11
Abstract: PROBLEM TO BE SOLVED: To provide a power circuit that implements reduced power consumption and improved reliability.SOLUTION: A power circuit 1 includes a relay 5, a main rectification circuit 22, a standby power circuit 3, and a main power circuit 4, and in a standby mode, it shuts off the output of the main power circuit 4. The relay 5 is inserted in a power supply path L1 from an external power supply 20 to the main power circuit 4 and is turned off in the standby mode. The main rectification circuit 22 is downstream of the relay 5 to rectify an AC voltage from the external power supply 20 before input to the main power circuit 4. The turnoff of the relay 5 in the standby mode can shut off voltage supply to the main power circuit 4 to reduce power consumption. Since the voltage whose supply is shut off by the relay 5 is the AC voltage yet to be rectified by the main rectification circuit 22, a shutoff shock applied to the relay 5 can be reduced to reduce the risk of failure.
