Abstract: 1494708 Semi-conductor devices FAIRCHILD CAMERA & INSTRUMENT CORP 19 March 1975 [3 May 1974] 11462/75 Heading H1K In a method of making a MOSFET, the edges 25 around an opening in an insulating layer 22 are smoothed by heating the wafer 8 in a step which also includes the formation of a layer 21 in the opening of the oxide of the dopant used to diffuse-in source and drain regions 17, 18. The oxide layer 21 is then converted predominantly into material of opposite dopant type which diffuses into the source and drain regions. These shallow regions of opposite type to the main source and drain regions are hydrophobic and provide a visual indication of etching completion in the etching step to remove the new material from the opening 24 prior to forming a terminal. In the embodiment described, source and drain regions 17, 18 are diffused from a layer 14 of boron oxide formed over SiO 2  layers 11a, 11b, the SiO 2  gate insulator and terminal 15a and conductive polysilicon layer 15b. An oxidation step produces an underlying layer 19 and an outer SiO 2  layer 22 is formed over the whole wafer. During smoothing of the edges 25, a layer 21 of boron oxide is formed in the contact opening 24 which is treated with POCl 3  resulting in a predominantly phosphorus oxide layer. The shallow surface oppositely doped layers in regions 17, 18 are formed during this treatment. After removal by etching of the phosphorus oxide which is etched faster than the insulation, a metal connection is formed in the opening 24, the smoothed edges 25 preventing cracking of the metal.

Title: Instruments for use in gauging workpieces
IPC: G01B3/22
Filed: 1959-04-07
Abstract: 888,221. Gauging ovality or non-concentricity of workpieces. MERCER Ltd., THOMAS, and WEATHERBY, J. March 31, 1960 [April 7, 1959], No. 11720/59. Class 106 (2). An instrument used to gauge ovality or non-concentricity of a workpiece A has a feeler rod 2 which slides in the casing 1 and carries a pin 3 in the path of movement of a lever 4 pivoted at 5. A second lever 6 is pivoted at 7 and the levers carry contacts 8, 9 connected to an electric relay (not shown). A magnet 11 is carried by the casing and is adjacent to the disc-shaped, pivot end of the lever 4. A plunger (not shown) slides in the upper part 13 of the feeler rod 2 and carries a pin 10. It is spring-urged upwards and is in threaded engagement with one part of a differential screw 15 the other part of which is screwed into the end 13 of the rod 2. Thus the pin 10 can be adjusted relatively to the rod 2. The pin 10 is mounted in the path of turning movement of the second lever 6 which is spring-urged downwards into engagement with it. When a workpiece A is placed in position the pins 3, 10 carry their associated levers upwards, the contacts 8, 9 remaining open. The workpiece is then rotated and when the diameter being gauged is the largest one of the workpiece the contacts are still open, Fig. 5. If the rotation is continued and this diameter is passed the feeler rod 2 drops and is followed by the spring-urged lever 6. The lever 4, however, remains in its highest position under the action of the magnet 11. If the difference between the largest and smallest diameters is within the required tolerance the contacts 8, 9 remain open. However, if this difference is too great the contacts 8, 9 close and a " reject " signal is indicated by apparatus controlled by a circuit including the contacts 8, 9.

Title: Improvements in or relating to electric synchronising apparatus
IPC: H02J3/42
Filed: 1927-05-03
Abstract: 294,970. Reyrolle & Co., Ltd., A., and Warren, T. R. May 3, 1927. Synchronizing dynamo-electric machines.- Means dependent upon the direction of relative rotation of, and upon the phase difference between, incoming and running machines control the closing of a synchronizing circuit-breaker. In a polyphase system, Fig. 1, the secondaries of voltage transformers D, E on the incoming and running machines respectively are each connected in star and one corresponding phase on each is earthed. The leading phases are connected together through a resistance F, to the mid-point of which a synchronizing relay G, responsive therefore at phase coincidence, is conneeted. This relay is adjusted to close the circuit J of the circuit breaker coil A' at g, Figs. 2 and 3, 25‹ before phase coincidence a and to open it at g<3> 25‹ after. The circuit J or the circuit of the coil G also includes a switch operated by an auxiliary relay H connected between non-corresponding parts of the voltage transformer windings, in the case shown the terminals of the leading phase of the incoming machine and the lagging phase of the running machine. So connected the periods of minimum excitation of the relay H occur at h, 60‹ before synchronism, a with a slow incoming machine, Fig. 2, and at 60‹ after with a fast one, Fig. 3. With the relay H set, to close at h<2>, 90‹ after minimum excitation and to open at h<1> 225‹ later, the synchronizing circuit can only be closed when the incoming machine is fast. The arrangement according to Fig. 1 is for interlocking a. manually-controlled switch-coil A', but may be applied to a wholly automatic system. The synchronizing relay may have a time-relay mechanism. By connecting the auxiliary relay between the leading phase of the running machine and the lagging phase of the incoming machine synchronizing will only occur when the incoming machine is slow. A modification is described with two auxiliaries relays to allow synchronizing either fast or slow. For wholly automatic working the instant represented by g is arranged nearer to the synchronizing position a, e.g. 5‹ from it by making the auxiliary relay to open at this point and to'close simultaneously contacts in the closing circuit of the circuit-breaker; the synchronizing relay is arranged to complete a maintaining circuit for itself when it closes. The point of zero excitation of the auxiliary relay may be adjusted by connecting it at one end to a, point on a resistance between the leading and lagging phases of the running machine transformer, a mid-position on this resistance giving zero excitation at 30‹ from the synchronizing position a. A wholly automatic system involving these modifications and comprising an automatic speed control of the incoming machine according to Specification 290,071 is also described.
