Abstract: A method for operating a digital logic semiconductor component, wherein: the logic semiconductor component is operated in several operational modes at respective fixed clock cycles depending on environmental temperatures; each operational mode is allocated a respective clock cycle with, in each case, a different clock frequency; each operational mode is allocated a respective temperature-dependent limit value with, in each case, a different limit temperature which when reached causes a change of operational mode to occur; and, when changing to an operational mode with a higher limit temperature, the clock frequency is reduced, and when changing to an operational mode with a lower limit temperature, the clock frequency is increased.

Abstract: A data transfer system has an address bus and a data bus, each divided into two parts by a bus switch. A microprocessor and program memory are connected to the first parts of the address and data buses. A data memory, data transfer controller, and input/output devices are connected to the second parts of tile address and data buses. While the microprocessor is fetching an instruction from the program memory, the bus switches disconnect the two parts of the buses, enabling the data transfer controller to transfer data directly between the data memory and input/output devices. At other times the bus switches connect the two parts of the buses, enabling the microprocessor to access the data memory and Input/output devices.

Abstract: A fuel cell generation apparatus including a plurality of fuel cells to be connected in parallel. Each of the fuel cells is connected in parallel with a serial circuit of a starting load and a switch. Each of the parallel circuit thus formed is connected in series with one of second switches, and the serial circuits thus formed are parallelly connected to form the fuel cell generation apparatus which is connected to a load. The starting loads are closed at the start of the operation of the fuel cell generation apparatus to drop the output voltages of the fuel cells to a voltage lower than a minimum voltage in no-load open-circuit voltages of the fuel cells. The fuel cell generation apparatus is started by closing the first switches, and then closing the second switches, and finally opening the first switches. This facilitates implementing a large capacity fuel cell generation apparatus whose efficiency is improved by eliminating diodes for preventing reverse currents from flowing.
