Title: Inspection device for foreign material in ic
Inventor: DOUKAWA YOSHIHIRO
IPC: G06T7/00
Filed: 1994-06-27
Abstract: PURPOSE:To properly detect a foreign material deposited on the lead of an integrated circuit without any erroneous judgement about a mold cutout remnant adjacent to an outermost lead as a 'foreign material'. CONSTITUTION:Data (d) covering all of leads for one side of an inspection object IC 2 is binarized at a binarizing level to make leads into '1's' through a binarizing circuit 6 and, then, at a higher level after counting the number of '1's' along a Y-axis direction, thereby obtaining the first binarized projection data (g). Also, data (h) resulting from the differentiation of the data (d) is binarized at a binarizing level to make lead spans into '0's' and at a lower level after counting the number of ''I's'' along a Y-axis direction, thereby obtaining the second binarized projection data (k). Regarding an X-axis direction, the position where the '0'' of the data (k) first appears, is retrieved in an outward direction from the position of '1' at both ends of the data (g), and provided that a span between the positions of two '0s' is taken as the range of a foreign material detection object, judgement is made as to whether the continuous numbers of '1's' and '0's' are within the preset range, regarding respective data (g) and (k) in the range of the foreign material detection object.

Title: Message communication processing system
Inventor: TAKAHASHI MASAYASU
IPC: H04L12/26
Filed: 1994-06-27
Abstract: PURPOSE:To maintain the stable message communication even at the time of the change of the condition or a fault or the like with respect to the system for message communication processing among plural processors constituting a parallel computer system. CONSTITUTION:Time information indicating the transmission time of a message is newly added as discrimination information of this message. Based on contents of the reception message and its time information, a reception destination processor P discriminates whether the message is a new message or a retransmitted message, and the processing corresponding to the discrimination result is performed. A repeating installation N abandons messages received over a certain time after transmission and changes an initially set transmission route to set a bypass route again in the case of a fault in another repeating installation N of the repeating destination. Thus, the load to the communication line is prevented from being quickly increased by the message retransmission processing or the like, and stable message communication is maintained to improve the reliability of the computer system.
