Abstract: Provided is a transfer device capable of suppressing shortage of memory resources even when the transfer device receives a diagnosis request from an external diagnostic equipment with respect to a plurality of electronic devices. A transfer device 20 receives a diagnosis request that is a message from an external diagnostic equipment 10 to a plurality of ECUs 18 from the external diagnostic equipment 10, and transfers the diagnosis request to some ECUs 18 out of a plurality of ECUs 18. Then, the transfer device 20 receives a diagnosis response that is a message from the ECU18 to the external diagnostic equipment 10 from some ECUs 18, transfers the diagnosis response to the external diagnostic equipment 10 and, thereafter, transfers the diagnosis request to ECUs 18 different from the above-mentioned some ECUs 18.

Abstract: Disclosed is a counterweight which is filled with a heavy-weight concrete containing, instead of currently used iron ores, a heavy-weight aggregate that scarcely causes the material segregation from cement paste and which can be produced at a low cost and is effectively enhanced in the filling factor of heavy-weight concrete into a case. A counterweight 6 comprises a case 62 and heavy-weight concrete filled therein, wherein the heavy-weight concrete contains a heavy-weight fine aggregate containing 20 mass % or more of aggregate particles having particle diameters of less than 0.15 mm and 20 mass % or more of aggregate particles having particle diameters of 2.5 mm to less than 5 mm.

Abstract: A mobile communication device includes power supply control switches corresponding to a local oscillator, transmitting frequency converter, receiving frequency converter, receiving amplifiers and transmitting power amplifier in a radio unit, and a battery saving control circuit in a control unit. By individually controlling the ON timing of the switches by means of the battery saving control circuit, it is possible, prior to a time slot period allocated to an individual mobile station, first to supply power to the local oscillator, then supply power to the frequency converters, and then supply power to amplifiers. By doing so the mobile communication device is set in a standby state for transmitting/receiving operation.
