A signal processing unit carries out signal processings necessary for a receiving/transmission processing of an adaptive array antenna. The signal processing unit also carries out a signal processing necessary for determining phase errors in quadrature modulation and quadrature detection to be done by radio units, namely, for determining a rotation amount of an initial phase correction value.

An object is to provide a cutting method capable of efficiently removing cutting chips around a cutting point with a little electric power, and cutting a work with high accuracy.

A ball end mill having a slit shaped-opening part at a portion adjacent to a rake face of a cutting edge and internally having a suction passage is used, and a work in which a cutting liquid is previously coated on an inclined face is cut while the cutting liquid is sucked in the area around the cutting edge from the opening part through the suction passage. As a result of this, in case of using non water-miscible cutting oil, when the cutting liquid in the area around the cutting edge is sucked from the opening part, a cutting power decreasing rate is higher than a case where the suction is not carried out.

An improved fuel processor for fuel cells is provided whereby the startup time of the processor is less than sixty seconds and can be as low as 30 seconds, if not less. A rapid startup time is achieved by either igniting or allowing a small mixture of air and fuel to react over and warm up the catalyst of an autothermal reformer (ATR). The ATR then produces combustible gases to be subsequently oxidized on and simultaneously warm up water-gas shift zone catalysts. After normal operating temperature has been achieved, the proportion of air included with the fuel is greatly diminished.

When a microcomputer does not charge an electric storage device, the microcomputer activates at an interval set based on a timer set value and determines whether an electric power voltage generated by a solar cell is equal to or higher than an electric power generation determination threshold. When the generated electric power voltage is lower than the electric power generation determination threshold, the microcomputer turns to a sleep state after increasing the timer set value by an addition set value while prohibiting charging the electric storage device. When the generated electric power voltage is equal to or higher than the electric power generation determination threshold and a generated electric power amount is equal to or larger than an electric power generation determination threshold, the microcomputer starts charging the electric storage device so the electric power device can be appropriately charged with an electric power generated by the solar cell.

The conductive polymer composition can contain melamine cyanurate so that it is flame-retardant.
