Title: Phase-sensitive detectors
Inventor: BOWES ROBERT COLIN
IPC: H03D1/22
Filed: 1967-12-13
Abstract: 1,246,449. Phase detectors. NATIONAL RESEARCH DEVELOPMENT CORP. 13 Dec.. 1968 [13 Dec., 19671, No. 56686/67. Heading H3A. A phase detector comprises a first pair of PNP transistors Tr1, Tr2, Fig. 5, in long-tailed pair connection, together with a second pair of NPN transistors Tr3, Tr4 also in long-tailed pair connection. Signals whose phase is to be determined are applied via terminal TP1 to the emitters of the transistors, via capacitors C2, C5 and resistors R6, R8. Comparison square wave switching signals are applied in one phase to the bases of transistors Tr1, Tr4 via terminals TP3, and in opposite phase to the bases of transistors Tr2, Tr3 via terminals TP2. An indication is obtained on voltmeter V, which is connected across RC network R1, C1 connected between the collectors of transistors Tr2, Tr4 and earth. According to the invention the tail resistors R2, R7 are connected to either end of a common floating power supply. The signal may alternatively be fed in between earth and the end of resistor R2, via capacitor Csup. In a modification the switching signals are applied to the transistors (Tr1-Tr4, Fig. 6, not shown) via field-effect transistors D.C. coupled to them. In a further modification the "tail" resistors are replaced by transistors Tr9, Tr11, Fig. 7, to which the signals are applied from terminal TP1 via D.C.-coupled field-effect transistors Tr1O, Tr12, respectively; the switching signals are fed in from terminals Tr2, Tr3 via field-effect transistors Tr7, Tr8, respectively. To obtain full-wave demodulation, a pair of the circuits described may be used with their outputs in parallel and driven with signals in push-pull.

A golf ball is mounted on one end of a first arm 4 mounted at its opposite end for rotation about the horizontal axis of a second arm 24, the ball and a lower portion 16 of the first arm being rotatable about its own axis. Means for counting the number of revolutions of the first arm about the second and means for detecting rotation of the ball and lower portion 16 of the first arm with respect to the upper portion 7 are included. Said first means comprises a screw threaded rod 26 pivoted to an end plate 36 of a clamp ring 32 rotatably securing, by means of a ball race 30, the arm 4 to the arm 24, the rod being rotatable in a bore 25 in said second arm and a nut 50, secured against rotation, cooperates with the rod. The second said means comprises the portion 16 being rigidly connected to an inverted U shaped housing 11, the upper portion 7 having an end portion 9 and washer 20 urged into engagement with the housing 11 by a spring 12. On striking the ball, the lower portion 16 may initially rotate relative to the upper portion 7, however centrifugal force due to rotation of the arm 4 about the arm 24 "locks" the two portions together. A braking device comprises an arm pivotally connected inside the clamp 32, spring urged towards an adjustable sleeve 49 on the arm 24, centrifugal force initially overcoming the action of the spring. The tensioning of the brake is adjustable by means of a screw 43 for use with differing golf clubs; the sleeve 49 may have parts of differing frictional coefficients. A further arm (64, Fig. 2) parallel to the arm 24 and having on one side an arcuate row of flexible fingers and, on the other, a putting gate formed by two members and a strap bridging said members, is rotatably mounted on a flange 62 rotatable on the arm 24 for rotation of either the fingers or the gate into the line of rotation of the ball about the arm 24, a side on the flange 62 indicates differing putting distances. The arm 4 is pivoted about the clamp ring 32 on a pin 8, a nut 13 locking it in position. A base plate having a pocket to fill with materials simulating differing ground conditions may be provided. The apparatus is adapted for use by left or right handed players.

Abstract: In a method of manufacturing a field effect semiconductor device, an insulating layer (e.g. nitride 11 on oxide 9) is formed as a first step on a suitably prepared surface of a substrate. This layer is subsequently selectively removed, leaving areas of the layer which carry an electrode structure, and the same layer is also used as a mask during formation of a relatively thick layer 13 of insulating material surrounding the device, preferably by thermal oxidation. The method is applicable to the manufacture of charge coupled devices and MOS transistors, and ensures that the channel region is subjected only to a single thermal oxidation process.
