An echo control system for an adaptive echo canceller which forms a pseudo-echo or its residual signal by combining respective outputs from a tapped delay line holding an estimated characteristic of an echo path as a tap weight and receiving a received signal or its residual signal as an input signal, subtracts the pseudo-echo or its residual signal from an echo signal or its residual signal, and corrects the tap weight using an amount of correction obtained by the resulting residual echo signal or its residual signal and the received signal or its residual signal. In accordance with the invention, there are provided a circuit noise estimation circuit for estimating a circuit noise of the echo path, a parameter error estimation circuit for estimating a parameter error between the characteristic of the echo path and its estimated characteristic, and a coefficient calculator for determining a correction coefficient obtained with the circuit noise, the parameter error and the received signal, wherein the said tap weight is corrected in accordance with the result of multiplication of the amount of correction and the correction coefficient. The system may be further provided with a device for transferring, as the said tap weight, the tap weight of the tapped delay line in the circuit noise estimation circuit when the circuit noise formed in the circuit noise estimation circuit is smaller than the residual echo signal.

The present invention provides microsphere manufacturing method and apparatus capable of stable obtaining microspheres of a desired size and reducing facility cost. According to the method and the apparatus, to manufacture microspheres made of a second liquid in a first liquid, the first liquid is supplied into a first channel to flow therein and the second liquid is supplied to an intermediate part of the first channel through a second channel. The supply velocities of the first and second liquids are set such that the second liquid closes the first channel and the closing part of the second liquid is cut off due to a pressure difference between an upstream side and a downstream side to form microspheres.

An inattention determining device includes range changing unit and inattention determining unit. When a curve detection result is output from curve detector, the range changing unit changes a first predetermined range to a second predetermined range by the predetermined amount in the curve direction before a turning direction of an acquisition result is changed in the curve direction of the curve detection result. The inattention determining unit determines whether or not a driver is in an inattention state on the basis of the second predetermined range.

A method of upgrading coal which comprises: pulverizing low-grade coal; mixing the pulverized low-grade coal with an oil to form a slurry; heating the slurry to or above the boiling point of water to vaporize the water contained in the low-grade coal and dehydrate the coal; compressing a vapor mixture of the steam resulting from the slurry heating and that part of the oil which has vaporized simultaneously and thereby elevating the temperature and pressure of the vapor mixture; and supplying the vapor mixture increased in temperature and pressure by the compression and utilizing this vapor mixture as a high-temperature heat source to heat the slurry. In the method, the vapor mixture before being compressed is brought into contact with an oil in a liquid state. This method is a process in which low-grade coal containing water in a large proportion and hence having a low calorific value is dewatered in an oil to thereby upgrade the coal to a high-calorie fuel for thermal power generation, wherein the vapor mixture to be supplied to a compressor can be purified.
