Abstract: PURPOSE: To inexpensively obtain an excellent naphthenic lubricating oil base stock, by contacting a lubricating oil crude stock obtained from a paraffin base crude oil with an extracting agent, separating the extract thereby to form a raffinate layer, and recovering the raffinate layer.  
     CONSTITUTION: A lubricating oil crude stock is introduced to a rotary disc extractor 2 through a conduit 1 and is contacted counter-currently with furfural introduced from a conduit 3. The furfural selectively dissolves and extracts aromatic components thereby to form the first extract layer. The extraction residue forms the first raffinate layer. The first extract layer is passed to a separation tank 7, after being cooled in a cooler 6 or after depletion of the solvent. In the separation tank 7, the first extract layer readily separates into the second raffinate layer containing saturated components and aromatic components and the second extract layer mainly containing aromatic components. The second raffinate from which the extracting solvent has been removed in a solvent stripper 13 is obtained from conduit 15, and is used as a naphthenic lubricating oil stock.

Abstract: PURPOSE:To receive TV signals of the B/PAL and M/NTS systems with simple circuit constitution, by switching horizontal frequencies of a horizontal oscillating circuit by a detection signal obtained by detecting output amplitude variations of a vertical oscillating circuit due to a difference in field frequency. CONSTITUTION:To a vertical oscillating circuit 1, the 1st and 2nd different vertical synchronizing signals for B/PAL system reception and M/NTSC system reception are inputted, and the 1st and 2nd saw-tooth waves which correspond to those synchronizing signals are outputted. The peak value of each saw-tooth wave is rectified by a peak rectifying circuit 2, whose peak rectification output is applied to a Zener diode 3. This diode 3 turns on when the rectification output exceeds some constant voltage, and the output of the diode 3 is inputted to a switch circuit 4, which outputs a signal different in level. This different level is inputted to a horizontal oscillating circuit inputting a horizontal synchronizing signal to switch horizontal oscillation frequencies automatically, thus receiving TV signals of the B/PAL and M/NTSC systems.

Abstract: PURPOSE:To attain a highly accurate position matching operation between a reference image and its subject image including a position error between both images and the rotational extents of both images by defining a relative coordinate system based on the centroid positions of two independent patterns and on an image plane of each pattern and collating both patterns with each other between the reference and subject images in the relative coordinate system. CONSTITUTION:The independent patterns 22 and 23 corresponding to the independent patterns 12 and 13 are detected. Then the relative coordinates x' and Y' are defined by the positions of the extracted patterns 22 and 23, and all independent pattern positions are registered in a repative coordinate system. Then two coordinate positions of all registered patterns are collated with each other by means of the relative coordinates. Thus the independent patterns corresponding to each other are detected. As a result, a reference-subject pattern table is obtained. Then the feature value of each pattern is obtained and the feature values of the patterns to be paired are collated with each other. Thus an image omission, etc., can be decided if the paired patterns have the different circumferential lengths, the different areas, etc. Then such decision data are obtained. As a result, the reference and subject images can be matched with each other with high accuracy.

Abstract: PURPOSE:To obtain a seal impression which is light but has a sufficient strength, and is strong against corrosion, transmutation or burning, etc., and does not chip at the time of processing, and also make precise machining for details easier and improve the precision of characters and design by a method wherein after having machined a conductive ceramic sintered body with an electrical resistance value of not more than 1OMEGA.cm into a seal impression shape, discharge processing is performed using an electrode machined into an impression form to engrave the impression form. CONSTITUTION:As a material for a seal impression, a sintered body of conductive ceramic with an electrical resistance value of not more than 1OMEGA.cm at room temperature is prepared. By cutting and then grinding this material, it is machined into a shape of seal impression, i.g., a cylindrical shape. The reason why the electrical resistance value of the conductive ceramic is kept not more than 1OMEGA.cm is that discharge processing is possible at or under 1OMEGA.cm. Then, the material machined into a seal impression shape is set in a discharge processing machine, and discharge processing is applied on one end surface to become an impression part, using an electrode which is previously made to correspond with the impression, to from an impression part 2 shown in figure 1. By this method, chipping etc. is not generated during the processing for the impression part, and precise machining for details of the impression part can be easily performed, and therefore, the precision of design such as characters, etc. can be improved.
