Abstract: Improved apparatus and technique for the circular weft knitting of articles including an improved knitting machine control synchronization system for computer control operation using independently operable, modular components. Needle selection for knit, tuck or float operation is effected by a unique presser cam system which flexes the lower end of compound needles outwardly where they are selectively and magnetically held or released according to a prescribed program to enter one or one set of plurality of cam tracks (3120) depending on the intended function of the needle. The upper end of the needles are positively engaged and held at a prescribed position above the fulcrum (3108) during such selection operation. A modified sinker element (2090) and sinker drive system accommodate an increased range of stitch length control and compensate for variations in yarn elasticity. The yarn knitting cylinder is directly driven by a hollow core motor concentrically arranged with respect to the longitudinal axis (1904) of the knitting cylinder.

Abstract: A phase signal estimator (1) receives a first phase signal having a first frequency and generates a first filtered signal phase-locked with the first phase signal as an estimated phase signal. A phase locked loop section receives a second phase signal having a second frequency which corresponds to a predetermined multiple of the first frequency of the first phase signal, and outputs a second filtered signal phase-locked with the second phase signal as a desired phase signal. In the phase locked loop section, a phase comparator (4) receives the second phase signal and the desired phase signal and generates a phase difference signal. A filter (5) low-pass filters the phase difference signal from the phase comparator. A signal generator (6) generates a signal having a predetermined frequency in accordance with the output from the filter. A phase adder (7) adds the signal having the predetermined frequency from the signal generator and the estimated phase signal from the phase signal estimator and outputs the desired phase signal. A frequency compensator (2) is selectively connected to the estimated phase signal, the second phase signal, and the desired phase signal so that the phase locked loop section has substantially the same low-pass filtering response characteristic as the first frequency of the first phase signal.

Abstract: A track seeking method is provided which relies on sampled seek information. No external sensors are employed and the seek information is intermittently stored along the tracks provided on the disk surface. In determining the actual velocity of the seek actuator, at least two methods for counting crossed tracks are utilized. Preferably, a 1/2-­count method is used at lower seek velocities and a 16-count method is used at higher seek velocities. The 1/2-count method involves the recept of two counts for each track that is crossed, while the 16-count method involves counting every sixteen tracks that are crossed. The selection of the 1/2-count and the 16-count methods for counting tracks crossed results in a velocity gap region. The velocity gap region is a range of seek actuator velocities in which the servo loop is underdamped for the 16-count method and where folding occurs for the 1/2-count method. To overcome the underdamping and folding problems, various solutions have been devised. In one embodiment, the velocity profile is configured so that the gap region is crossed in a relatively short amount of time and the 16-count method is used in providing velocity feedback.

Abstract: Inductive proximity sensor for detecting an object (3) having electrical conductivity comprising a sensor housing, a measuring coil (L1) and reference coil (L2) placed on either side of a plane of symmetry (10) through the sensor housing. Each coil (L) is partly surrounded by a piece of magnetic material (8) which leaves the measuring coil (L1) or reference coil (L2) respectively free at the front which faces the direction of the object (3) to be detected or a reference member (9). An electronic circuit is provided for supplying both coils (L) with an AC signal and for measuring the change in a specific property of the measuring coil (L1) with respect to that of the reference coil (L2) when an object (3) approaches and determining therefrom the distance (d1) or the presence of the object (3). The pieces of magnetic material (8) around the two coils (L) are formed essentially from the same homogeneous material forming a block. Means (4) are provided in the sensor housing for screening magnetic fields produced by both coils (L) in order to suppress thereby mutual crosstalk. The electronic circuit for each coil has a separate synchronous detector with its own oscillator for effecting a frequency-selective measurement such that the effect of changes in the properties of the magnetic material and of the measuring coil on the detection distance is compensated for electronically. Both oscillators of the synchronous detectors have a frequency offset from each other.

Abstract: A collision detection system with less computation time and higher performance is provided. The shortest distance between the surface of one object and the surface of another at the beginning or end of a period to be checked is compared with the sum of the maximum length of paths along which points of the surface of the one object move in the period, and the like of the another. If the former is bigger than the later, then it is sure that the two objects can not collide in the period. If not, it is not sure, and the period is divided into two parts, and then such a test is done for each partial period. Such a test and dividion are recursively performed until the whole period is ensured to have no collision or an approximate collision is detected, which is easy to be so. The approximate collision is defined as a state of the shortest distance between the surface of the one object and the surface of the another being less than a perdetermined minute threshold. THis in vention is useful in CAD/CAM system in particular for off-line robot movement teaching.
