Abstract: PURPOSE:To enhance a reliability to a heat cycle by a method wherein protrusions are provided on the peripheral parts of a chip or at one side or the both sides of two sites on a substrate to oppose to the chip and the interval between the surfaces of the chip and the substrate is regulated. CONSTITUTION:Bump electrodes 2 are provided on the central part of a chip 1 and protruded bodies 5 are provided on the four corners in the peripheral parts of the chip 1. The protruded bodies 5 consist of solder in the same manner as the bump electrodes 2, but are higher than the bump electrodes 2. This chip 1 is placed on an insulating substrate 3 facing downward the surfaces of the bump electrodes 2 in such a way that the bump electrodes 2 oppose over wiring conductor layers 4 coated with solder layers 41 on the substrate 3. At that time, as the protruded bodies 5 are higher, the bump electrodes 2 do not come into contact to the solder layers 41, but when they are heated, the chip 1 sinks when the protruded bodies 5 are welded to solder layers 61 and the bump electrodes 2 come into contact with the solder layers 41. As a result, the coupling parts 7 between the bump electrodes 2 and the solder electrodes 41 are expanded and are formed in a snare drum form.

Filed: 1987-08-11
Abstract: PURPOSE:To easily insert an endoscope device into the deep position of a pipe to be inserted with said device even if the inside surface of the pipe cavity has foreign matter, rust, etc., by ejecting air jets backward from the ejection holes opened to the wall part forming a space communicating with a channel hole. CONSTITUTION:The high-pressure air fed from the channel hole 6 flows through a communicating pipe 8 to the space part 9 of the front wall part 11 and flows into a space part 10 existing in the rear wall part 12 through a communicating path 15. The high-pressure air flowing into the space parts 9, 10 ejects the air jets from the respective ejection holes 17, 18 toward the diagonal rear side of the insertion part 1. This air jets float the insertion part 1 to form a spacing 21 with the inside surface of the pipe 20 which is the object to be inspected. The friction force to the pipe 20 is, therefore, decreased and the pushing force is decreased. The insertion part is thus easily inserted into the deep part of the pipe without being affected by the foreign matter, rust, ruggedness, etc., and without being caught by the same even if such foreign matter, etc., exist on the inside surface of the cavity, etc., of the pipe to be inserted with said part.

Filed: 1992-07-27
Abstract: PURPOSE: To provide a method to precisely measure a period of time when the external interruptions are inhibited by executing a special version program into which a specific intentional malfunction is inserted. CONSTITUTION: A scan program 120 generates a special version program 122 from a changed source code.
