Granted: 2002-09-17
Abstract: A product and a process for producing a matrix and a tool for use in abrasive or cutting applications including a base tool structure which may be armed with a plurality of triangular or conically shaped structures (24B) consisting of abrasive particles (32) bonded together in a braze metal (38). The structures (24B) may be prepared in a manner which provides a selectable rake angle. Rake angles including negative (46), neutral (46') and positive (46") may be produced. The process is accomplished by dif-fusing magnetizable abrasive particles on a release mechanism which has been placed on a reusable fixture (10) consisting of a plurality of balls (16) secured to a magnetized surface (14). The particles (32) stack to form structures (24) which are then encap-sulated in a braze paste (26). The axis of the structures (24) is aligned with the applied magnetic field, The cones are symmetrical if the magnetic field emanates perpendicularly from the magnetized surface. If the orientation of the magnetic field is distorted the conical structures will realign themselves therewith. In this manner conner conical structures (24) may be formed which offer selectable rake angles. The matrix (22) foamed by encapsulating the abrasive particles (32) may be removed from the release me-chanism (18) and secured to a base structure (30). Once this assembly has been brazed, the base structure may be used as an abrading or cutting tool.

Title: Detecting location of time slot where data begins using pointer in justification or stuffing synchronous tdm
Inventor: KANEKO HIROAKI
IPC: H04L7/08
Filed: 1992-06-29
Granted: 1997-12-30
Abstract: In a synchronous TDM communications system wherein the data is transmitted after being subject to zero, negative or positive justification, a location of a time slot where data having a predetermined length begins, is specified by detecting a pointer.  The pointer, which is included in a demultiplexed channel information, is extracted from the demultiplexed channel information. Further, a pointer value indicative of the predetermined length is detected.  Still further, a justification status is also detected using the pointer extracted.  On the other hand, a timing signal is received which corresponds to the zero justification.  A pointer offset is produced using the timing signal, while another pointer offsets are generated by advancing and retarding the pointer offset by one time slot.  Subsequently, one of the three offsets is selected depending on the justification status.  A comparator compares the pointer offset selected and the pointer value and outputs a signal indicative of the first time slot of the data in the event that the comparison coincidence has been detected.
