摘要:
Attitude control is implemented by detecting the phase difference between signals received by at least two antennas and detecting the angle of deflection between the direction of arrival of radio signals and the antenna beams. By using antennas that are separately driven, within the plane of rotation in which the deflection angle is to be detected, the phase of the received signals can be shifted equivalently to when the antennas are driven as a consolidated unit. Also, when at least three antennas are used in an orthogonal arrangement for detecting the deflection angle in two directions, the antennas are divided into two groups which are individually driven. This reduces the inertia of the moving parts and enables the size and weight of the drive mechanisms to be reduced. In addition, two orthogonal functions are used to represent the phase of the deflection angle of the direction of arrival of the radio wave and the antenna beam as a multiplicity of quadrants, and by storing these, when there is a change in the deflection angle, the sequence of change can be traced back and the control effected accordingly. This enables pointing error to be eliminated.

The object of the present invention is to neutralize acidity of bio-oil so as to allow practical use of bio-oil as fuel. Neat liquid of acidic bio-oil is flow in the treatment bath 1. Magnesium powder is added to the liquid from the input chute 3 and the mixture is stirred in the stirrer 7 until the magnesium powder is completely dissolved. The treated oil is taken from the outlet tube 4. The hydrogen gas generated is collected by the suction duct 5, and the reaction heat generated is collected by the heat exchanger 6.

摘要:
A bent pipe forming apparatus for extruding and forming a fluid material into an annular member having a central mandrel (22) and a die (21) defining an annular gap between the mandrel (22) and the die (21), wherein one of the mandrel (22) and the die (21) is supported to move in a direction perpendicular to an axis of the mandrel (22). The movable mandrel (22) or die (21) is provided on its outer periphery with a guide circular surface (XX) integral therewith. An inner movable ring (4) having inner and outer circular peripheries eccentric to each other is rotatably fitted on the guide surface. An outer movable ring (5) having inner and outer circular peripheries eccentric to each other is rotatably fitted on the periphery of the inner movable ring (4). The outer movable ring (5) is provided with an outer circular peripheries which is rotatably fitted in a stationary circular guide surface (YY). Driving motors (12a, 12b) are provided to independently move the inner and outer movable rings (4, 5).
