Title: Semiconductor package
Inventor: YAMAMOTO MATSUKI
IPC: B29C45/26
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of failures such as a void or a sink, etc., without controlling under a severe molding condition by providing a resistant shape to suppress the resin flow at the end part parallel to the filling direction of resin. SOLUTION: In a semiconductor package wherein a semiconductor chip 4 is mounted on a die pad 2 of a lead frame 1, a lead pin 3 is allowed to project and the entire body is packaged with resin, a resistant shape is provided to suppress the resin flow at the end part in such a direction parallel to the filling direction of resin 5. That is, a tapered part is formed in a manner that the thickness of the resin at a position excluding a semiconductor chip or die pad is made small. In such a semiconductor chip, the flowing resistant of the resin 5 therein becomes because the thickness of the tapered part 6 is small, so that the resin 5 is hard to flow. As a result, the flowing of the resin 5 at both the central part including the chip 4 and the end part on the side of the lead pin 3 can be made uniform and the filling failure hardly occurs.

Abstract: PURPOSE:To switch the combustion without allowing the time for an exhaust-gas purge, that is, dead time, in switching of the alternated combustion of regenerative burners so as to enhance safety and enable enlarging the equipment and reducing exhaust loss. CONSTITUTION:Burners (main burner part with nozzles 4) are alternately burned in a setup to store in a heat reservoir 2 of one of the burners while the burner is not working the sensible heat of the combustion exhaust that passes through the heat reservoir 2. When, immediately after an alternating switching of the combustion and at the burner turned on, the combustion exhaust inside the piping from the heat reservoir 2 to a four-way switching valve 6 is drawn toward the heat reservoir 2 and forced into the burner under a push by the air for combustion, oxygen is fed into the combustion exhaust which is flowing into the heat reservoir 2 so that the combustion exhaust now containing thus fed oxygen is reacted with the fuel in a manner of combustion.
