IPC: H05K3/34
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To improve reliability of solder connection and packaging density by making a constitution where a lead is led out from at least one out of the bottom of a package and a surface facing the bottom and is laid along the side surface of the package. SOLUTION: A semiconductor device is provided with a lead frame 7 which has been formed beforehand such that a lead 71 is led out from the bottom 5 of a package or an upper surface 6 facing the bottom 5, and a structure where a package 9 is formed by resin encapsulation after electrical connection of a pellet P is obtained, and the lead 71 is bent along a side surface 91 of the package 9 and stretched as far as a surface which face the surface from which the lead 71 is led out. That is, at the time of resin encapsulation, forming is so performed that the lead frame 7 is led out from the bottom 5 or the upper surface 6 of the package 9, and the lead length can be set to be more long.  As a result, the area of the lead 71 which is connected with solder at the time of soldering becomes adequately wide, and high connection reliability is obtained in spite of the semiconductor device of a small package.

Title: Steam generator
Inventor: OKAMURA KENJI
IPC: F22B1/28
Filed: 1987-12-18
Abstract: PURPOSE: To obtain an inexpensive highly stable steam generator, by interposing a faucet packing incorporating a compression spring between the front end of the threaded part of the main body of a water supply tank and the bottom face of the threaded part of a faucet, so that the spring may tightly bring the bottom face of the threaded part of the faucet into contact with the front end of the threaded part of the main body by pressing the bottom face against the front end. CONSTITUTION: A compression spring 32 is inserted between the upper and lower sides 31a and 31b of a faucet packing 31 having a U-shaped cross section, so that the spring 32 may urge the upper and lower sides 31a and 31b upward and downward. When the threaded part B28a of the faucet 28 is screwed in the threaded part A27a of the main body 27 of a water supply tank 26, in such a state that the front end 27d of the threaded part A27a and bottom face 28b of the threaded part B28a can come into contact with the packing 31, the upper and lower sides 31a and 31b urged by the spring 32 are respectively pushed by the front end 27d of the threaded part A27a and the bottom face 28b of the threaded part B28a, and the connection between the main body 27 and faucet 28 can be sealed highly airtightly.  Even when the tightening force becomes weaker at the time of screwing the threaded part B28a in the threaded part A27a, the connection can be sealed surely as far as the weakened tightening force falls within the range of elastic deformation of the spring 32. Therefore, the tank 26 can stably supply water, because no air gets in the tank 26 from the connection.
