摘要:
A fuel cell power generator having an output controlling system for preventing the deterioration of the fuel cell performance caused by fuel gas shortages. The fuel cell power generator includes a fuel reformer, a fuel cell, an inverter, and an output controlling system. The output controlling system includes an output control regulator for controlling the output power of the inverter as close to the current value corresponding to the output power set value as possible, a current command computing unit, an inverter controller, and an output correction section. The output correction section includes an available output computing unit for computing the maximum available output power value of the fuel cell on the basis of the detected flow rate of fuel gas flowing into the fuel cell or fuel exhaust gas flowing out of the fuel cell; a low level selector for selecting either the computed maximum available output power value or the output power set value, whichever is the lower; and an output correction regulator for supplying the output control regulator with a signal for correcting the output power set value so as to control the detected output current from the fuel cell as close to the current value corresponding to the output current value of the low level selector as possible.

The present invention provides a sealing member for fuel which includes a fluororubber base and a sliding-treated layer coating the surface of the base. The sliding-treated layer includes a matrix made from a fluororubber, a sliding thin film formed in the surface portion of the matrix from a molten first particulate solid lubricant, and a second particulate solid lubricant dispersed in the matrix and the sliding thin film without being melted.

An account transfer process instructing system uses payment request information issued from a payment request institution device that performs payment requests to the user to thereby process authentication of the person in question. When a payment instruction is made by the user, the account transfer process instructing system executes transfer processings to transfer payments from the user's bank accounts to an account of the payment request institution.

Financial advisory methods and systems for creating a steady lifetime income stream within an investment plan is provided. According to one embodiment, based on an investor's current holdings in the investment plan, a pattern of periodic cash payouts is identified that can be made to the investor from an in-plan payout program implemented with the limited universe of financial products available within the investment plan. The assets of the investment plan are rebalanced to form a payout portfolio and an equity exposure portfolio. The payout portfolio is constructed to create an annuity-like stream of income to support the pattern of periodic cash payouts and includes multiple bond funds. The equity exposure portfolio is constructed to address inflation risk by providing an ability to rise with equities markets. Finally, a periodic cash payout of the pattern of periodic cash payouts is caused to be paid to the investor from the investment plan.

In producing rod-form high-purity polycrystalline silicon by depositing silicon on a silicon core by the thermal decomposition of a silane gas, the occurrence of defects near the interface of the silicon core and polycrystalline silicon newly deposited thereon is prevented. A silicon core before depositing silicon thereon is subjected to a hydrogen treatment. In this case, the treatment temperature and the treatment time are controlled according to the dew point of the hydrogen gas. After the hydrogen treatment, the hydrogen gas in a reactor may be replaced with a high-purity hydrogen gas, followed by producing a polycrystalline silicon by a silane gas.
摘要:
A hot diffusion welding method wherein a first part generally made from a material different from a second part and the second part made from copper alloy are united with an insert material interposed between the joint faces thereof under a heated and pressurized condition. The insert material at the joint between the first and second parts is copper plating formed on the joint face of the first part made from the different material, so that the thermal conductivity between the two parts is improved to perform smooth resistance heating. This enables continuous welding operation without polishing the conductive surfaces of a pair of electrodes in order to eliminate oxides therefrom.When the insert material interposed between the joint faces of the two parts is a normal brazing filler metal, resistance heating is carried out with an even number of superposed bodies in each of which the second part, insert material, first part are superposed, the superposed bodies being assembled in such a manner that the respective second parts are brought into contact with each other. In this case, the first parts having a greater thermal capacity are in contact with the pair of electrodes, whereby polishing for eliminating oxides from the conductive surfaces of the electrodes is no longer necessary and continuous welding operation can be thus accomplished.

There is disclosed a system for predicting desynchronization of a synchronous machine by detecting a phenomenon of radical variation of the magnetic flux in the gap of a synchronous machine immediately before falling in an asynchronous state. For example, a functional value of the fundamental harmonic component and that of the higher harmonic component of the flux in the gap are detected for comparing the variation of each functional value with a predetermined reference level to predict desynchronization of the synchronous machine.

Desynchronization of a synchronous machine is predicted by detecting a phenomenon of radical variation of the magnetic flux in the gap of a synchronous machine immediately before falling into an asynchronous state. For example, each functional value of the direct axis flux and the quadrature axis flux in the gap is detected for comparing the variation of each functional value with a predetermined reference level to predict desynchronization of the synchronous machine.
