Abstract: 1,091,450. Cutting tools. GENERAL ELECTRIC CO. Dec. 23, 1965 [Feb. 16, 1965], No. 54544/65. Heading B3B. A tool comprises a shank 4 having a recess and a seat 2 for a cutting bit 1 and a locking pin 3 which is loosely threaded to the lower portion 15 of a hole in the shank beneath the cutting bit and seat; when tightened down, a tapered portion 17 of the pin 3 makes wedging contact with an offset tapered portion 14 of this hole to force the upper end of the pin 3 against the side of a hole 21 in the cutting bit thereby locking the bit against the shoulder face of the recess. In order to hold the cutting bit 1 firmly on seat 2 the pin 3 has an enlarged portion 18 positioned to make contact with the side of hole 21 near the lower face of the cutting bit while the shoulder of the recess is disposed at a slight angle with the face of the cutting bit so that the latter contacts the shoulder near its upper edge. To facilitate the wedging movement of the pin 3 the threaded portion 16 is made very slightly convex. In a modification (Fig. 6, not shown), the seat is omitted. In another modification (Fig. 5, not shown) the cutting bit is formed with positive rake and the hole therein and the complementary portion of the locking pin are tapered. In this embodiment the axis (C-C) of the hole in the cutting bit is offset from the axis of the pin and shank hole in a direction away from the shoulder of the recess. Triangular, square or circular cutting bits (Figs. 7-9, not shown) may be employed.

Title: Ultrasonic scanner with nonoverwriting gray-scale storage
IPC: A61B8/00
Filed: 1974-12-24
Abstract: 1495539 Ultrasonic inspection devices ROHE SCIENTIFIC CORP 24 Dec 1974 55859/74 Heading G1G In an ultrasonic pulse-echo system providing a visual image of an object area scanned by a transducer, echo signals are fed to a storage tube which for each image point stores the intensity of only the strongest echo produced by multiple scans of the corresponding object point, and the stored intensities are used to form the image. This technique ensures display intensity fidelity by preventing "overwriting" of image parts when some object points are scanned more times than others. One embodiment, for medical diagnosis, uses a transmit-receive probe with one rotational and two translational scan components to form A-scan and B-scan displays on respective CRT display units. A conventional scan-converter of the storage-tube type is used. With the converter in the "write" mode its target is flooded with electrons to record a uniform charge pattern. This pattern is then selectively erased imagewise by the echo signals. At any point of the pattern the degree of erasure depends on the maximum echo intensity arising from multiple scans of the corresponding object point. Finally, the converter is used in the "read" mode to drive the B-scan display unit. The A-scan unit is driven by the echo signals without storage.

Abstract: 1291448 Semi-conductor devices WESTERN ELECTRIC CO Inc 21 Nov 1969 [22 Nov 1968] 56971/69 Heading H1K An insulating guard ring defining the periphery of a planar rectifying surface barrier on a Si substrate and extending into the surface beyond the depth of the rectifying barrier is formed by means of a gas plasma of oxygen, nitrogen or carbon or combination thereof such as NO+ or CO<SP>+</SP>. The barrier may be a metal/  semi-conductor contact, e.g. Al on Si, but in the embodiment shown it comprises a layer 13 of a silicide of a metal such as Ni, Ti, Zr, Hf, or a Pt-group metal on an N type Si body 11. The silicide 13 is formed by heating the body after evaporation or sputtering of the appropriate metal, either over the entire surface or, as shown, within a window in an oxide layer 12 produced by steam or plasma oxidation or by pyrolytic deposition. The silicide 13 is covered with layers of Ti 14 and Pt 15 and a central portion of these layers is masked with a thicker layer 16 of Au. The exposed areas of Ti and Pt are then rernoved by back-sputtering, and the thus exposed silicide is converted to oxide extending beyond the depth of the remaining silicide 13 by means of a high energy oxygen plasma. If Pt silicide is used it must first be removed by back-sputtering, since it resists oxidation. In a second embodiment a metal silicide layer is formed over the entire surface of a Si body (21), Fig. 2 (not shown), and a localized area of this layer is masked with a layer (23) of a metal such as Au, Ti, Al, Ta, Nb, W, Zr or Hf, to which leads may next be applied. The whole surface is then plasma-oxidized to a level (24) below the Si/ silicide interface, and the portion (22) of silicide underlying the metal mask (23) is left undisturbed, defining a planar rectifying barrier with the Si body (21) surrounded by an insulating guard ring.
