Title: Remote eddy current defectoscope
Inventor: KURUMAYA HARUMICHI
IPC: G01N27/90
Filed: 1991-06-25
Abstract: PURPOSE:To securely inspect an abraded and thinned part of a metallic tube or the like by obtaining the difference of outputs of a pair of magnetic detecting elements arranged symmetrically at both sides in the axial direction of a transmission coil. CONSTITUTION:A transmission coil T is magnetized by a power source 30. The outputs of the same polarity from first transmission coils R1A. R2A are added to a differential output means 13, where the difference of the outputs of the coils R1A, R2A is obtained. A level distinguishing means 14 judges when the output of the differential output means 13 exceeds a preset value, making a display means 15 indicate the fact. Similarly, the differential outputs of receiver coils R1B and R2B, R1A and R1B, and R2A and R2B are respectively displayed by display means 18, 21, and 24. If a metallic tube 7 is abraded at a part 25, and the coil R1A is present at the part 25 while the coil R2A is at the other position than the part 25, the outputs of the receiver coils R1A, R2A become different and the differential output level from the differential output means 13 exceeds the distinguishing level set by the level distinguishing means 14. As a result, the display means 15 displays the abraded and thinned part 25. Thus, the inspection of an abraded and thinned part is made possible.

Title: Anchor rod capable of being fixed by curing substance
Inventor: ORIBAA BERUHITORUDO
IPC: F16B13/14
Filed: 1987-06-22
Abstract: An anchor rod assembly includes an axially elongated anchor rod to be secured in a borehole by a hardenable mass inserted into the borehole around the anchor rod. The anchor rod is divided by slots into a plurality of circumferentially spaced axially extending segments extending from the leading end of the anchor rod. The anchor rod has an axially extending central bore located radially inwardly of the segments. A filler piece is inserted into the central bore and the slots between the segments. The filler piece closes off the slots between the segments at the outer circumferential surface of the anchor rod. Due to the filler piece, the hardenable mass cannot flow into the slots between the segments and the central bore. As a result, the segments follow movement of the borehole wall during any widening of the borehole because of cracked development, and the anchor rod is retained in the borehole. A radially inwardly formed constriction in the outer circumferential surface of the segments adjacent the trailing end of the anchor rod improves deformability of the segments.

IPC: G03G15/05
Filed: 1979-11-29
Abstract: PURPOSE: To enable remarkable reduction of imaging time, by imagewise exposing a photoreceptor with a precharged toner ribbon superposed between the photoreceptor and an opposite electrode.  
     CONSTITUTION: Light projected from the side of transparent electrode layer 3 is absorbed near the electrode side of photoconductive layer 4, and the irradiated part of layer 4 is made conductive. Charge on layer 3 induced by voltage applied between layer 3 and opposite electrode 6 moves to the border face between layer 4 and support tape 8a of toner ribbon 8 only at the irradiated positions, a strong electric field is produced across tape 8a and toner layer 8b between said charge and charge 20 on the surface of layer 8b, and since the area of this dot is small, discharge begins between them. Once discharge begins, the current continues until charge 20 on layer 8b is neutralized with the charge moving through layers 3 and 4, and the discharge current is stopped by peeling of layer 4 from ribbon 8.
