Title: Pulse laser welding method for aluminum alloy
Inventor: MATSUNAWA AKIRA
IPC: B23K26/32
Filed: 1993-01-13
Abstract: PURPOSE:To join an aluminum alloy without a weld defect such as a weld crack, etc., by irradiating with a pulse laser beam. CONSTITUTION:Four pulses LB (1) to LB (4) are repeated with an intermittent time (for instance, lmsec) in a laser output waveform per one time or one cycle. The peak values of these pulses LB (1) to LB (4) go down successively, that is, in order of LB (1), LB (2), LB (3), and LB (4). When the weld zone of a material to be welded, being made of an aluminum alloy, is irradiated with such a pulse laser beam LB, a crack does not occur except for only on the surface part of a molten metal part in a weld zone. The crack occurred on this surface part does not cross the joint surface of the material to be welded, and it is not a weld defect.

Title: Self-routing channel system
Inventor: URUSHIYA SHIGEO
Filed: 1988-01-29
Abstract: PURPOSE:To continue routing by bypassing a stage element in which a fault is generated by using a spare migration link and an inter-spare stage link by providing the inter-spare stage link between elements on the same row of adjacent stages. CONSTITUTION:Routing information (d) is attached on communication information by a routing information attaching circuit 2-4. Since the routing information (d) is the difference of an output line number 3(output line 4-3) and an input line number 4(input line 1-4), it goes to (3-4)mod4=3. The value of routing communication information is reduced by 1 since the routing information is not 0 in the element E41, it is transferred to the element E12 via a migration link Y12, and is transferred to migration links Y23 and Y34 similarly in the elements E12 and E23. Since the routing information is 0 in the element E434, it is transferred to an inter-stage link X35, and the routing information of the routing communication information is eliminated by a routing information elimination circuit 3-3, then outputted to the output line 4-3.
