Title: Semiconductor switching device for power device
Inventor: KURACHI KAZUHIRO
IPC: H03K17/72
Filed: 2001-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor switching element that prevents power loss from being concentrated on a part of a wafer of the element, furthermore enhances the turn-on capability of the element, can be downsized and simplified. SOLUTION: An on-gate current rising rate diG/dt is controlled so that a ratio of (a main current rate of rise di/dt at turn-on)÷(on-gate current rate of rise diG/dt at turn-on) is 1.25 or below. For example, when an anode reactor in a main circuit is decreased to a half of that of a conventional switching element to rise a main current increasing rate to be 1000 A/μs, the on-gate current rate of rise is controlled to be 800/μs or over. The inductance of a loop including the element and a gate driver is reduced to 1/3 of the inductance of the conventional element and the capacitance of a capacitor of a part generating an on-gate current in the gate driver is enhanced to be a required capacitance to attain the above.

Inventor: GALICKI PETER
IPC: H04L12/701
Filed: 2001-08-13
Abstract: PROBLEM TO BE SOLVED: To achieve a pull transfer and transfer reception confirmation in a data pipe routing bridge. SOLUTION: In the network of digital signal processor nods which are connected in peer-to-peer relation, return transmission from a node is performed with a data packet sent to the node. A requester digital signal processor sends the data packet to a target digital signal processor (1001). After the data packet reaches the target digital signal processor, its receiver expels the arrival request packet into an I/O memory to trigger a transmitter interruption (1002). Then the transmitter executes a pull request packet (1003) on the next packet border by a pull interruption (1004). Lastly, the transmitter extracts part of a local I/O memory by the execution of the pull request and send it back to the requester digital signal processor (1007). At the same physical part of the I/O memory, two logical uses of a receiver channel and a transmitter code block are overlaid.
