Abstract: A charging circuit includes a generator, a step-down circuit for reducing an output voltage of the generator to a predetermined voltage, a current controller for controlling a charging current that is supplied from the step-down circuit to a secondary battery, based on an amount of power generated by the generator, a mode selector for selecting charging modes, and a monitor for monitoring an amount of stored electricity. The step-down circuit receives an output of the generator, in charging, at a high voltage and a small current and is used to charge the battery at a low voltage and a large current.

Abstract: A packet relaying apparatus includes queues holding packet information, and queue control units controlling dequeueing. The dequeueing means transmission of packet information from a queue of a previous stage to a queue of a next stage. The packet relaying apparatus further includes a packet information control unit that, on receiving packet information to be dequeued at the time of dequeueing, returns discard information and data volume corresponding to the received packet information, a first bandwidth adjusting unit that, on determining that the received packet has been discarded, discards the packet information, maintains a usable bandwidth, and transfers the discard information and the data volume to the previous stage, and a second bandwidth adjusting unit that, on receiving the discard information and the data volume from the next stage, adds the data volume to the usable bandwidth and transfers the discard information and the data volume to a previous stage.

Abstract: A resin composition includes a polyester capable of forming a crystal structure, at least one member selected from uracil and a uracil derivative used as a nucleating agent. A resin molding obtained from the composition is also provided.

Abstract: A material for acoustic apparatus housing, which is advantageous not only in that it prevents the resin from suffering corrosion and is unlikely to impose a burden on the environment, but also in that it has excellent performance as an acoustic apparatus housing. A material for acoustic apparatus housing, characterized in that it comprises a biodegradable polymer compound, an inorganic material, and a hydrolysis inhibitor.

Abstract: According to the present invention, a water absorbent material and materials to be sucked included in a water permeable bag type member form a water absorber. Thus, the water absorber is small both in weight and volume upon its transportation, and accordingly, the water absorber can be rapidly conveyed in large quantities without depending on a human power. The water absorber absorbs water upon its use to adequately satisfy a function of a form traceability for weight, volume and outline.

Abstract: A reactor comprising a reacting vessel 31 that contains a fluid including high temperature and high pressure water under target reaction temperature and reaction pressure condition and performs a reaction treatment to a reactant by the fluid, a first pipe 25 connected to the reacting vessel 31 to supply the reactant to the reacting vessel 31, and a first partition means 50 for partitioning between first pipe 25 and the reacting vessel 31 so as to prevent a leakage of any one of the fluid, the reactant, and a reaction product from the reacting vessel 31 side to the first pipe 25 side. The first partition means 50 is comprised of for example a valve 51, a shaft 52, a weight 53, a supporting member 54, and a pipe 55, and normally, due to the weight 53, the valve 51 closes an opening of a bottom end of the pipe 55. That is, it isolates the pipe 55 and the inside of the reacting vessel 31.
