Title: Magnetic detecting method and apparatus therefor
Inventor: ANDO SEIGO
IPC: G01N27/82
Filed: 1992-02-24
Granted: 1996-07-02
Abstract: In a magnetic detecting method of the invention, a low-pass filter (107) extracts the low-frequency signal component contained in a signal (106) output by a mag-netic sensor (104) which detects a leakage flux result-ing from a magnetically defective portion of an object (101) moving in a magnetic field.  The low-frequency signal component extracted is amplified and supplied to a compensating coil (111).  The compensating coil (111) generates a magnetic flux, which cancels out a floating flux crossing the magnetic sensor (104).     A magnetic detector of the invention comprises a low-pass filter (107) for extracting the low-frequency signal component contained in a signal (106) output by a magnetic sensor (104) which detects a leakage flux resulting from a magnetically defective portion of an object (101) moving in a magnetic field; an amplifier (110) for amplifying the low-frequency signal component extracted by the low-pass filter (107); and a compensat-ing coil (111) excited by a signal output by the amplifier (110), for generating a magnetic flux which cancels out a floating flux crossing the magnetic sensor (104).

Abstract: A method of continuously painting one side of a moving substrate metal strip (1) utilizing a thermosetting polymer based paint composition comprises pre-heating the strip in a pre-heat furnace (2) to a pre-heat temperature above the glass transition temperature of the paint composition, driving a solid block (8) of the paint composition into collision with the strip at a predetermined block speed to cause liquid paint to be melted from the block and applied to the strip at a precisely controlled deposition rate. The deposit, which for thin paint coats is discontinuous, is then spread over the surface of the strip by a pressure roll (14) and emerges therefrom as a smooth coat of wet paint. A bead of liquid paint (17) builds up on the strip on the up stream side of the pressure roll and the block speed may be adjusted in response to the bead size. The emergent strip then travels through a paint curing furnace (5) and a bath (6) to complete the process.

Abstract: A robotic gripper module, which can be fitted to a robotic arm or other support means, houses a rotor which is rotatable relative to the frame of the module. The rotor has at least two equiangularly positioned slots, each extending at the same relative angle to a radius of the rotor. A cam follower mounted on radially-moveable slide members is positioned in each of those slots and also in a respective radial slot in the module frame, and rotation of the rotor causes the cam followers and slide members, on which finger assemblies may be mounted, to move together radially inwardly or outwardly on the frame. An arcuate gear segment on the periphery of the rotor meshes with a gear rack on one end of a rod; the other end of the rod connects to a piston-and-cylinder actuator. In one form of the module two rotors rotate on a single axle, one on each side of the module. The two rods associated with the two rotors extend from opposite sides of the cylindrical space between the rotors, and the pair of associated actuators are positioned outside that space. This arrangement allows for a thin module with a significant space saving over other robotic modules.

The lower body port ion, which includes a plurality of longitudinally extending projections, is poled in a first direction generally orthogonal to bot h its longitudinal and vertical axes. The upper body portion also includes a plurality of longitudinally extending projections. The l ower and upper body portions are mated such that the lower and upper body projections are spaced interdigitally with each other.

Abstract: In a telephone network having a number of telephone switching offices which have CCS7 signalling capabilities and wherein each switching office is linked to STPs  (Signalling Transfer  Points),  or  other  switching  offices  with  CCS7 signalling links,  a method of detecting mass calling events using CCS7 signalling data is disclosed.  Each signalling link connecting a switch is monitored.   For each call, an Initial Address  Message  sent  from  an  originating  switch  to  a terminating switch is identified.  The IAM is then temporarily stored in storage means.   When the occurrence of a release message  indicative  of  an  unsuccessful  call  attempt  is detected,  an  identification  of  which  of  the  stored  IAMs corresponds  to  the  release message  is  made.    A count  is computed  for  each  directory  (DN)  having  an  IAM  with  a corresponding release message indicative of an unsuccessful call  attempt  such  that mass  calling  events  directed  to  a directory number can be detected.

Abstract: A speech compression system called "Transform Predictive Coding", or TPC, provides for encoding 7 kHz wideband speech (16 kHz sampling) at a target bit-rate range of 16 to 32 kb/s ( 1 to 2 bits/sample). The system uses short-term and long-term prediction to remove the redundancy in speech. A prediction residual is transformed and coded in the frequency domain to take advantage of knowledge in human auditory perception. The TPC coder uses only open-loop quantization and therefore has a fairly low complexity. The speech quality of TPC is essentially transparent at 32 kb/s, very good at 24 kb/s, and acceptable at 16 kb/s.
