Abstract: PURPOSE:To obtain an evaluating value indicating the painting sharpness with good correlation to the visual evaluation by a method whereby the rough shape of a painting surface is subjected to the frequency-conversion, and the texture adjusted by the obtained spatial frequency is separated and digitized, so that the sharpness of said painting surface is quantitatively evaluated as a function of the texture. CONSTITUTION:A measuring apparatus 1 for measuring the surface roughness sweeps the painting surface of a sample 3 on a vibration-proof base 2 with a diamond needle at a constant speed, and changes the vertical movement of the needle due to the roughness of the painting surface to waveforms of a voltage changing with time. This apparatus 1 is controlled by a controller 4. The result measured by the apparatus 1 is indicated by a plotter 7 and recorded by a printer 8. An analog signal obtained by the apparatus 1 is A/D converted in a Fourier transform apparatus 5 and frequency- analyzed through Fourier transform. Accordingly, the roughness of each frequency component is quantified as a power spectrum. The roughness of each frequency component obtained by the apparatus 5 is integrated by a computer 6 in a range of wavelengths corresponding to three kinds of the texture of the painting film, i.e., smoothness, roughened surface feeling and glossiness, or such an operation as weighing integration etc. is conducted.

Abstract: PURPOSE:To obtain a device which can transmit the high-speed and large-capacity information with a long life time, by securing a contactless transmission of the information by use of the optical system having the same optical axis as the shaft of the turntable. CONSTITUTION:The signal to be transmitted to turntable 5 is originated from information source 1 in the form of the electric signal and then converted into the photosignal through electro-optical converter 2 to reach rod lens 4 through optical fiber 3. The optical axis of lens 4 coincides with the center axis of table 5, and the lower face of lens 4 is opposing in vicinity to the upper face of rod lens 6 attached to the center of table 5.

Thus the electric signals necessary for the apparatus within the turntable are transmitted. Accordingly, the large- capacity information can be transmitted even to the rotor having a long life time and a high-speed rotation.

IPC: G21C7/00
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To set the flow rate of core to the lower limit in the operating range during rated and normal outputting (equilibrium xenon state). SOLUTION: Xenon is accumulated in plenty in the upper side of a core such that the output distribution in the axial direction of core may be a peak in the upper side in the control rod pattern before the completion of final control rod pattern, and the output distribution in the axial direction is made to be a peak in the lower side at the completion of the final control rod pattern, by the deviation of distribution of xenon in the axial direction, and then the xenon is accumulated in the lower side in the axial direction of core from the completion of the final control rod pattern to equilibrium xenon state of core. Such an accumulation of xenon reduces the lower peak of the output distribution, so that the quantity of void in the lower side of core can be reduced and its average fraction be also reduced.
