摘要:
According to the present invention, a control apparatus for an electric generator includes a power generation cost determiner determining a power generation cost of the generator, a threshold determiner determining a threshold of power generation cost as a function of a state of charge of an electric energy storage device, a comparator comparing the power generation cost of the generator with the threshold, and a controller. When the power generation cost of the generator is lower than the threshold, the controller controls the generator to generate an increased amount of electric power, so as to both charge the electric energy storage device and feed an electrical load. Otherwise, when the power generation cost of the generator is higher than the threshold, the controller controls the generator to generate a decreased amount of electric power, so as to allow the electric energy storage device to discharge to feed the electrical load.
摘要:
An electric power generation control apparatus mounted to a motor vehicle predicts an operational point of an internal combustion engine in the future based on driving path information supplied from a navigation system mounted to the motor vehicle. The apparatus further predicts an increased amount of fuel consumption which is caused by electric power generation of an alternator based on the predicted operational point of the internal combustion engine. The apparatus sets a reference value of an electric power economy index which is an amount of fuel consumption per electric power generation. On driving the motor vehicle on a path, the apparatus sequentially predicts the operational point of the internal combustion engine, and controls the alternator so that the actual electric power economy index becomes equal to the reference value based on the operational point of the internal combustion engine predicted.

A first bit-sequence, which is to be transmitted from a control section to an authentication chip according to an encoding scheme that transmits each one and zero by a pulse with a width of 200 μsec and 100 μsec respectively, is converted to a second bit-sequence to be transmitted according to NRZ encoding. The converted second bit-sequence is stored in a register with the MSB of the second bit-sequence aligned in the MSB of the register. Timing to set the pulse width for transmission of a one or zero by NRZ encoding is performed repeatedly, and at the start of each timed interval, the signal transmission level output to the authentication chip is set corresponding to the value of the bit stored in the MSB of the register. After setting the signal transmission level, the register is shifted left one bit.

Provided is an aligning method capable of setting a sample observation unit such as an optical microscope to a probe microscope observation position at high precision. A sample having a known structure is used in advance. A surface of the sample and a shape of a cantilever provided with a probe are observed using the sample observation unit such as the optical microscope. A sample observation position and a probe position which are obtained using the sample observation unit are verified, and a relative positional relationship therebetween is recorded. Then, a first mark indicating a position of the cantilever and a second mark which is displayed in conjunction with the first mark and has the relative positional relationship with the first mark are produced to align the sample relative to the second mark.

The present invention relates to an optical fiber product suitable for fabricating an optical cable that requires a complicated length adjustment. The optical fiber product includes an effective use portion used as the optical cable, surplus portions connected to both ends of the effective use portion, and a distinguishing structure clearly indicating boundary portions between the effective use portion and the surplus portions. With the above structure, the surplus portions that become finally unnecessary are surely cut off in a fabrication step of the optical cable, thus enabling collect use of only effective use portion as the optical cable.

Positive-side and negative-side voltage power lines of each of the positive-side and negative side voltage management ICs are connected to positive-side and negative-side output terminals of the battery equipment so that all the battery modules supply electric power to each of the voltage management ICs. The voltage management ICs have a common ground line.
