Abstract: A system is used for cooling a fuel cell arrangement, particularly a fuel cell arrangement with a gas generating system in a motor vehicle. A coolant circuit for the system is connected to a cooler, a coolant delivery device, a fuel cell and at least another component to be cooled. The coolant circuit has at least two valve devices which are each assigned to the fuel cell and the at least another component to be cooled. By means of the valve devices, a flow rate of the coolant through the fuel cell or the another component to be cooled can be influenced as a function of the temperature in the region associated with the fuel cell or the another component.

Abstract: A sigma delta circuit is provided having a sigma delta modulator configured to operate according to a first clock signal and a quantizer connected to the sigma delta modulator, where the quantizer is configured to operate according to a second clock signal. In operation, if a small amplitude signal is received by the sigma delta circuit, the circuit is configured to operate at a fixed output frequency. When a large amplitude signal is received, the circuit is configured to adjust to a different frequency to accommodate the larger signal. The second clock signal may be a variable clock signal, where the quantizer operates according to a variable clock signal in order to adjust to different input signals.

Abstract: A speed meter unit has a magnetic pointer position detector, including an output coil, a detection coil and a magnetic piece. The output coil generates magnetic flux. The detection coil is for detecting the magnetic flux from the output coil. When a pointer has returned to an initial position, the magnetic flux generated in the output coil can reach the detection coil through the magnetic piece, so that a microcomputer can detect the initial position of the pointer. Such the magnetic pointer position detector is resistive to the soil or the oxidization, so that the speed meter unit can detect the initial position of the pointer accurately and securely.

Abstract: A shock absorbing and magnetic levitating cushion used as a supporting pedestal for an audio-video equipment, the cushion including a housing, two mutually excluded annular magnets, a magnetic conductive member and a cover. The housing has two annular magnets mutually excluded and opposite to each other, and has a magnetic conductive member filled with material of high specific weight. The housing is covered with a cover. According to the principle of mutual exclusion between two poles of two magnets of identical polarity, the two annular magnets undergo a magnetic-levitating phenomenon and are provided therebetween with a space for movement, and the magnetic levitating cushion gets an effect of shock isolation and shock absorbing.

Abstract: A composition for treating a keratin based substrate that includes a cosmetically acceptable medium containing a water-soluble interjacent complex. The water-soluble interjacent complex includes a first water-soluble polymer and a second water-soluble polymer formed by polymerizing one or more water-soluble monomers in the presence of the first water-soluble polymer. The water-soluble interjacent complex is characterized in that it forms a solution in water that is free of insoluble polymer particles. The water-soluble interjacent complex is used in a method of treating a keratin based substrate, whereby a cosmetically acceptable medium is applied to the substrate and contains from 0.1-20% by weight of the water-soluble interjacent complex.

Abstract: The circuit comprises a differential amplifier with two inputs and two outputs and a common mode regulation circuit. Between a regulation terminal of the amplifier and the outputs there are connected first and second capacitors and first and second capacitive elements that by controlled switches are connected in parallel with, respectively, the first and second capacitors or alternately between first and second reference voltage terminals. The common mode output voltage is not exactly fixed at the beginning of the design, but is determined by attributing appropriate values to the first and second capacitive elements; more particularly, their capacitances C3 and C4 are chosen in such a way as to satisfy the following equality: Vcmn=Vrefl+[(Vrefp?Vrefm)/2]*(C4?C3)/(C3+C4), where Vcmn is the desired common mode output voltage, Vrefp and Vrefm are the differential output voltages and Vrefl is the voltage of the second reference terminal.

Via rollers clamping tight the long and short adhering sections synchronically for fastening thereof, the inner and outer blind layers are automatically assembled with large hollow arc patterns formed at the front section of the combined inner and outer blind layers, and small hollow arc patterns disposed at the rear side of the large transverse V-shaped folding sections thereof.

Abstract: A dynamotor capable of operating as either a motor or a generator is used with both the armature portion and the field portion thereof capable of being rotated. In the case where a pulley operatively interlocked with the output shaft of the prime mover is mounted on the rotary shaft of the armature portion, the drive shaft of the compressor is mounted on the rotating field portion. Once the dynamotor is operated in motor mode, the rotational speed of the compressor is increased to the sum of the input rotational speed and the rotational speed of the dynamotor. The compressor is stopped by disconnecting a power feed circuit. When the input rotational speed is too high, the dynamotor is operated in generator mode. In this way, the rotational speed is reduced in accordance with the generated electric energy.
