IPC: H04L12/56
Filed: 1989-12-19
Abstract: PURPOSE: To reduce the size, the complexity, and the cost of a communication network by dividing reception packets by transmission destinations and sorting groups independently of one another combining sorted groups again by plural expansion-type output switches. CONSTITUTION: An output path 103 of a distributor 101 is connected to inputs of sort units 104 to 107 with a prescribed pattern. Reception packets received by the distributor 101 are equally distributed to sort units based on output switches of transmission destinations of arriving packets by this connection pattern. Intermediate sort units 104 to 107 are sorted into plural groups based on output switches 108 to 115 of transmission destinations of packets. By a merging part of sort unit groups of output switches 108 to 115, groups of these packets are combined again so as to be finally connected to output ports.

Title: Method and device for detecting phase error between phase current and drive voltage
Inventor: CHEN HAO
IPC: H02P6/16
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To control a motor in a large-capacity storage by determining a limit where signals indicating a phase current are symmetrical around the middle point of time intervals and generating phase error information accordingly. SOLUTION: In a phase detection circuit 36, a phase current 92 generates phase error information by measuring symmetry around a middle point 100 in an observation window 98. When the phase current 92 is a symmetry around the middle point 100 in the observation window 92, its low peak 101 is aligned with the middle point 100. On the other hand, when the phase current 92 is asymmetrical, it is not aligned with the middle point 100 but the degree of asymmetry is related to a phase error. In the observation window 98, current flowing to a sense resistor 48 is within a specific time interval where current from one of three electrical coils of a motor 20 is predominant, so that the phase detection circuit 36 processes a voltage crossing the sense resistor 48 and can means the symmetry of the phase current, thus controlling the motor in a large-capacity storage.
