Title: Apparatus for use in a borehole to measure an electrical parameter of the formation surrounding the borehole
Inventor: MEADOR RICHARD A
IPC: G01V3/30
Filed: 1989-08-10
Abstract: In a well logging apparatus and method for measuring the resistivity of the formation surrounding a borehole two transmitting antennae (167, 181) are arranged around a housing or a drill collar in spaced relation from one another. A transmitting circuit (165, 179) alternately supplies an oscillating drive signal to each transmitting antenna (167, 181) with a sufficiently high frequency and such that one and then the other of the transmitting antennae (167, 181) radiates an electromagnetic wave signal which propagates through the formation. Two receiving antennae (175, 177) are located equally spaced between the transmitting antennae (167, 181) to produce pick-up signals from the electromagnetic wave propagating through the formation. Each receiving antenna (175, 177) includes a single turn coil connected in series with a capacitor to provide a reduced impedance circuit to resonate in the frequency region embracing the oscillating drive signal. Receive antenna circuitry (169) responsive to induced alternating current in the coil produces a signal indicative of the formation parameter under study. The method of positioning two series resonant single turn receiving antennae (175, 177) tuned to the oscillating drive frequency and alternately coupling an electrical drive signal to the pair of transmitters (167, 181) spaced equally on each side of the receiving antennae (175, 177) allows receiving signals which are self-cancelling for system-induced effects. <IMAGE>

Title: Optical fibre 1 to N splitter
Inventor: CASSIDY STEPHEN ANTHONY
IPC: G02B6/28
Filed: 1990-03-06
Abstract: An optical splitter comprises a primary optical fibre 36 which may have a D-shaped cross-section (D-fibre) which crosses at least two, e.g. three, secondary D-fibres 38, 40, 42 to form three cross-couplers by evanescent coupling of their cores. Equal splitting of an optical signal propagating along the primary fibre 36 is achieved by appropriate coupling constant of the cross-couplers achieved by fanning the secondary fibres 38, 40, 42 to provide different interaction lengths with the primary fibre 36. Another embodiment (Fig. 2) employs different separations of primary and secondary fibres to achieve the same result. <IMAGE>

Title: Automatic document feeder capable of feeding a document in the form of a computer form
Inventor: HASHIMOTO KENJI
IPC: G03B27/62
Filed: 1990-09-04
Abstract: An automatic document feeder (ADF) for use with an electrophotographic copier, digital copier or similar image recorder feeds ordinary documents in the form of separate sheets and a continuous document in the form of computer form (CF) paper 10. Sprocket holes formed through the CF paper are sensed 114, 116 to controllably transport and stop the CF paper on the basis of the number of sensed holes. A timer operates between successive detections of sprocket holes so that intervening cuts for fastening a carbon to the CF paper are ignored. Also if no sprocket hole detection is made after a predetermined time then the paper is considered jammed. The sensor 114, 116 is upstream of the image forming platen 40 so hole detection stops before the final page of CF paper has boon positioned. A pulse generator or timer then operates to bring the final page into position. <IMAGE>

Title: Attachment of inserts by press forming
Inventor: PHILLIPS JOHN CLIFFORD
IPC: F16B15/00
Filed: 1992-03-27
Abstract: An attachment means is applied to a fibre mat (18) by application of pressure which may be applied simultaneously with heat in the formation of a rigid article from the fibre mat. The attachment means comprises a plate (11) having two sets of perpendicular teeth (14), each tooth having a chisel point (15) and a weakened portion (16) on one face. The weakened portion yields under pressure when the fibre of the fibre mat (18) resists penetration of the teeth (14) under pressure. The sets of teeth are oppositely weakened (16) so as to be either splayed apart or crimped together when the attachment means is subjected to pressure. Applications for the attachment means include the attachment of stiffening ribs to interior covers and linings for use in vehicles made of resin impregnated waste textile fibre or similar material. <IMAGE>

Filed: 1992-05-07
Abstract: An analog-to-digital converter 103 converts an analog composite video signal on the basis of a sampling clock generated by a VCO 111 with a frequency four times that of a subcarrier. A BPF 113 extracts an input subcarrier from the digital composite signal. A local subcarrier reference generator 112 generates a local subcarrier. A multiplier 114 detects the phase differences between the input subcarrier and the local subcarrier. An averaging (I) circuit 115 averages consecutive 4 n phase differences and an averaging (II) circuit 116 further averages the averages thus obtained over a plurality of lines. A pulse generator 117 generates a pulse signal with a width corresponding to the averages thus obtained and an integrator 118 integrates the pulse signal thus generated thereby to control the oscillating frequency and phase of the VCO 111. <IMAGE>

IPC: H03L7/10
Filed: 1993-01-13
Abstract: A frequency synthesizer which can effect a high speed frequency hopping operation without causing deterioration in stability in phase and frequency in a phase frequency-locked condition and also in output spurious characteristic is disclosed. An output range controlling circuit (1) clips the output voltage of a phase frequency to voltage converting circuit (2) at a voltage corresponding to an input signal (3, 4). The phase frequency to voltage converting circuit (2) outputs a voltage corresponding to a pulse width inputted thereto from a phase frequency detector (7). A low-pass filter (11) removes high frequency components of a signal inputted thereto. A voltage-controlled oscillator (10) outputs a signal (5) having a frequency corresponding to a voltage of a signal having passed through the low-pass filter (11). The phase frequency detector (7) effects phase frequency detection between a reference signal (6) and a signal obtained by frequency dividing the output (5) of the voltage-controlled oscillator (10) by an arbitrary value by a variable frequency divider (8). <IMAGE>
