IPC: H03K3/03
Filed: 1990-11-06
Abstract: A method and apparatus for recovering a clock signal from a random NRZ data signal is shown to include a phase detector (22) for detecting the phase difference between the random NRZ data signal and a clock signal and for generating a phase signal representative of the phase difference. The phase signal is a binary signal having first and second logic levels, wherein the first logic level is representative of the clock signal having an early phase relationship with the data signal and wherein the second logic level is representative of the clock signal having a late phase relationship with the data signal. Clock recovery also incorporates an integrator (24) for integrating the phase signal over a period of time and for generating an integration signal representative of such integration and an oscillator (26) for generating the clock signal at a clock frequency responsive to both the phase signal and the integration signal. The clock frequency is determined by a centering factor and an offset factor. The centering factor is controlled by the integration signal and the offset factor is controlled by the phase signal. There is also shown a particular phase detector (36,38,40,42,44), several integrators and a preferred oscillator (28,30,32,34) for practicing the invention.

Abstract: There is disclosed a power source apparatus for an alternating-current arc welding. In the power source apparatus, a reference signal generator periodically generates a reference signal having a predetermined waveform, and a direct-current power source outputs a current periodically changing in response to the reference signal, the outputted current having a waveform corresponding to that of the reference signal. Thereafter, a switching circuit supplies an alternating-current welding current to a welding load so as to sequentially change the polarity of the welding current from a straight polarity to a reverse polarity and from the reverse polarity to the straight polarity in synchronization with the reference signal by switching the current outputted from the power source in response to the reference signal.

Abstract: This invention relates to a method of identifying attributes when documents are grouped to form document relationships within a document management system. Document groupings frequently require the identification of all documents within the relationship with a particular attribute. However, when individual documents store attributes along with document contents, individual querying of each document is required when the information is sought later. This invention provides a Vector Relational Characteristical Object, available to access mechanisms, and containing fields to identify a particular attribute. Each field in the Vector Relational Characteristical Object is followed by an identifier which uniquely identifies the document which possess the particular attribute.

Abstract: A fluid connector and lock combination is described for connecting a tube (40) to a base element (12). The relatively fixed, threaded base element (12) has a passageway for pas­sing fluid. A threaded mounting connector (42) for surroun­ding the circumference of a portion of a tube (40) is provided and which also mounts the tube (40) to the relati­vely fixed, threaded base element (12) through threaded en­gagement. The connector (42) maintains a seal between the tube (40) and a corresponding surface in the base element (12) when the connector (42) is sufficiently threaded to a sealed position relative to the base element (12) to prevent leakage of fluid across the seal. A linkage (30,124) is provided between the connector (42) and the base element (12) for preventing unthreading of the connector (42) from sealed position relative to the base element (12). The linkage in­cludes a first portion (124) which is linked to the connec­tor (42) and a second portion (30) which engages slidingly in an axial direction the base element (12) for preventing relative rotation between the connector (42) and the base element (12).

IPC: H03M7/40
Filed: 1991-02-22
Abstract: A coding system comprises the comparing circuit which compares a magnitude of the range on the number line which is allocated to the most probability symbol with a magnitude of the fixed range on the number line which is allocated to the Less Probability Symbol. If the range allocated to the MPS is smaller than that to the LPS, and when the symbol is the MPS, the range allocated to the LPS is generated. If the range allocated to the MPS is smaller than that to the LPS, and when the symbol is the LPS, the range allocated to the MPS is generated. By the system, a coding efficiency is improved especially when a probability of occurrence of LPS (Less Probability Symbol) is approximate to 1/2.

Abstract: A computer system coordinates the handling of error codes and information describing errors in a commit procedure. The system supports a first resource manager of a first type and a second resource manager of a second type. An application is coupled to a sync point manager and initiates a two-phase commit procedure. The sync point manager is coupled to the first and second resource managers and coordinates the two-phase commit procedure involving the first and second resource managers. The sync point manager receives notification of a failure or failures relating to the first and second resource managers that prevent completion of the commit procedure and identification of the resource manager or resource managers associated with the failure or failures. The sync point manager sends to the application a failure notification after receipt of the notification of a failure or failures relating to either or both of the resource managers, and upon request, also sends to the application the identification of the resource manager or resource managers associated with the failure or failures. The sync point manager also receives cause of failure information for each failure, and sends the cause of failure information to the application upon request.

Abstract: A method for synchronously interlocking feed axes (Z1, Z2) of a lathe is disclosed. In particular, a numerical controller (NC) controls the operation of a lathe by sending position command signals to servo amplifiers (30, 31). The lathe turns a long workpiece (5) chucked by two opposed headstocks (12, 22) which are driven synchronously. The servo amplifiers (30, 31) send signals to corresponding directional servo motors (14, 24) for moving the headstocks (12, 22) in respective directions. The present invention overcomes the problems of mechanical and workpiece displacement developed as loads on the servo motors (14, 24) by compensating for the positions of the feed axes (Z1, Z2) by means of position offset values determined from the displacement of the machine or workpiece (5). Specifically, the displacements are detected in accordance with a difference between the torque of the two feed axes (Z1, Z2) to be controlled for synchronous interlocking. In this manner, the displacement of the machine or workpiece (5) is compensated for by moving the headstocks (12, 22), which are synchronized in the corrected positions.

Abstract: A device (10) for marking curved surfaces of workpieces, for example casting moulds, has a tool holder (28), which is movable in the three planes perpendicular to one another and on which a writing head (13) is held, and a work holder (38), by means of which the workpiece (11) to be marked can be rotated about an axis. Superimposed on this rotary movement of the workpiece (11) to be marked is a linear movement of the writing head (13) in a direction perpendicular to the axis of rotation and to the transverse extent of the workpiece (11). The two movements are interlinked in a predetermined manner. It is thereby possible to mark, essentially over their entire periphery, workpieces (11) with curved outer and/or inner surfaces (12) and, when used on casting moulds or the like, to at the same time easily demould moulded parts to be produced with the casting moulds even from solid or hard materials, which ease of demoulding is adequate over the entire surface. <IMAGE>

Abstract: The present invention forms non-magnetic particles in a acicular shape as dispersed in a dispersoid liquid, forms a lower non-magnetic layer by coating the above-mentioned dispersoid liquid on a continually transported non-magnetic supporting base, forms an upper magnetic layer by coating the above-mentioned magnetic coating liquid in dual layers either consecutively or at the same time while the lower layer is still in its wet state, and performs an orientation of the magnetic particles by exposing the particles to a magnetic field while the dual layers as thus formed are still in their undried state. The orientation effect is achieved by making the specific gravity of the non-magnetic particles equal to or greater than that of the magnetic particles. The orientation effect is further enhanced by making the particle size of the non-magnetic particles equal to or less than that of the magnetic particles as measured along the long axis of the magnetic particles.
