Abstract: PROBLEM TO BE SOLVED: To detect an underwater potential difference gradient between reference electrodes by arranging two or more reference electrodes for measuring the underwater potential difference gradient to the detector opposed to a steel material under the surface of the water at an equal interval. SOLUTION: Fine measured values at respective places in water measured between a steel material and a reference electrode 2 under the surface of the water and fine measured values at respective places in water measured between both potential difference gradient measuring reference electrodes 3, 4 are amplified to definite magnitudes suitable for handling by first and second ISO amplifiers 5, 6. Next, the steel material potential detection signals showing the potentials at respective places in water corresponding to the steel material and the potential difference gradient detection signals showing potential difference gradients at respective places in water are obtained and these detection signals are recorded and stored in a deta recorder 7 as measured data.  Further, the steel potential detection signals are set to reference values by a chart recorder 8 to further obtain potential difference gradients from the underwater potential difference gradient measured values to be diagrammed on a solid graph. By this constitution, the consumption state of anticorrossive current flow anode and the corrosion state of the steel material can be judged locally and concretely.

Title: Optical disc
Inventor: FUJIMOTO NOBUYUKI
IPC: G11B7/24
Filed: 1984-10-29
Abstract: PURPOSE:To eliminate the influence of the meander of a substrate which protects a recording film and to make focusing and tracking highly precisely by coating on the substrate protecting a recoding film a substance whose reflective index is larger than that of the substrate. CONSTITUTION:A laser light 4, passing through a glass substrate 2, is reflected by a recording layer 1 and returned to an optical head. The reflective index of the substrate 2 without a coating material 3 is assumed as n1 and the meander of the surface as l1, and when a substance 3 of the reflective index of n2 is coated on the surface, the meander of the surface is reduced to (d). The reflective index of the substance 3 is selected so that the optical distances of the raised part and the lower part of the surface winding be equal. Thus, the variance in optical distance caused by the meander of the substrate is reduced with the thin coating without raised in precision of the substrate surface.

Title: Picture reader
Inventor: NAKAJIMA AKIO
IPC: H04N1/00
Filed: 1987-09-10
Abstract: PURPOSE:To coincide with the center of an original at the time of magnification and at the time of a variable power by reading a prescribed pattern and detecting the center of the original by means of a picture reading means. CONSTITUTION:An optical system is moved to a pattern position, and since a distance from the pattern position to an original tip position (the tip of an original area on an original loaded glass 4) is already known, the value is set as the travel of a scan motor. Next, both edges of a black-plastered pattern 16b of a pattern 16 are detected, and the center address of a CCD9 is calculated by both edge addresses. Next, the optical system is moved by the scan motor to the tip position of the original. Since the travel is known in advance, scanning can be started correctly from the tip position of the original at the time of the variable power. When the optical system reaches the tip position if the original, an effective picture signal is turned ON, and the picture reading by a CCD8 is started. Therefore, the center of the picture output is not dislocated when the same original is made from unmagnification to variable power.
