Abstract: A wide range monitor apparatus for the output from a nuclear reactor has a logarithmic count rate measuring circuit and a Campbel measuring circuit corresponding to different neutron flux density ranges of the neutron flux output from a neutron detector. The apparatus monitors the nuclear reactor output as a single output which has a linearity with the neutron flux density over a wide range thereof. A logic circuit combines two comparison discrimination signals obtained by comparing low and high comparison voltages corresponding to the hysteresis width in an overlap region of the outputs from the two measuring circuits with detection output voltages from the two measuring circuits. One of the outputs from the two measuring circuits is selected in accordance with the logical level signal obtained by combining the two comparison discrimination signals by the logic circuit.

Abstract: A device for conversion between flow and rotation includes a fixed revolution center shaft integrally provided with a center sprocket, at least one vane having a self-rotation shaft and turnable about the revolution center shaft and on the self-rotation shaft, a vane sprocket fixed to the self-rotation shaft and having twice as many teeth as the center sprocket, and a chain connecting the two sprockets, whereby the vane rotates through 180.degree. on the self-rotation shaft while it revolves around the revolution center shaft through 360.degree.. The device, even if made comparatively small in size, can efficiently convert energy of a flow to rotational energy or vice versa since the orientation of the vane or vanes is continuously varied to enhance the efficiency. Thanks to the self-rotation of vane, the device has an additional advantage that foreign substances, such as string, rope and straw, are automatically removed.
