Title: Multipath torus switch device
Inventor: HAWAADO TOOMASU ORUNOUITSUCHI
IPC: H04L29/06
Filed: 1993-09-10
Abstract: PURPOSE: To provide a torus switch of short waiting time. CONSTITUTION: The connection time of a torus network is improved by supplying ability to try multiple paths by one high-speed operation. The multipath method is for simultaneously establishing connection between two specified nodes by various routes. When only one route is possible, the multipath method immediately finds the path and establishes desired connection with the minimum waiting time. When some links are possible, the multipath method establishes the desired connection by only one link among them and releases the other options for the other connection. Route selection in an intermediate torus network stage is the substantial improvement of a wormhole method.

Filed: 1988-10-04
Abstract: PURPOSE:To obtain an optical recording and reproducing device where information is not left unerased by making the diameter dimension of a beam for erasing on a recording medium larger than that of a beam for recording on it. CONSTITUTION:In the optical recording and reproducing device which records the information on the recording medium by the beam for recording 6 and erases the information recorded on the recording medium by the beam for erasing 8, astigmatism is introduced to the beam for erasing. Then, a beam spot 8 on the recording medium is converged in a track direction and extended in the width direction of a track. Due to such constitution, even when the beam spot for erasing 8 and a recording track 5 are relatively deviated in the width direction of the track, the beam spot for erasing 8 is still on the recording track 5 and the expanded part of a first layer 2 is continuously irradiated with the beam for erasing. Thus, all projections 4 on the recording track 5 disappear and the information is surely erased.
