Title: Method of fabricating a semiconductor device comprising a metal deposition process
Inventor: KATSUYA KOSAKI
IPC: D06M23/14
Filed: 1992-02-05
Abstract: In order to form a solder pad for a field-effect transistor electrode (2), on this electrode, which constitutes a base metal layer, an amorphous layer of Ni-P is formed, obtained by chemical deposition, which eliminates the effects of the crystalline nature of the base metal layer; and next, on the amorphous layer, an electrolytic gold plating layer (9) is formed.

Title: Bird trap, with automatic reset - has a pivoting landing platform, which tips bird into holding cage, and then returns to await next one.
Inventor: YVES BOSSE
IPC: A01M23/04
Filed: 1992-07-06
Abstract: The birds are attracted, by the lure of bird calls or by food, to land and rest on the external part of the platform (2), which is stabilised by the support (3).  As it advances towards the interior, it passes through the entrance and crosses over the pivot axis. The platform tips under the action of the weight of the bird and the bird slides into the holding cage (5).  If the bird overcomes its surprise and tries to fly off, the anti flight case (1) acts to prevent the bird from flying away and it drops into the cage. The platform returns to the horizontal position thus sealing off the access hole. USE/ADVANTAGE - It produces a large holding cage with a simple and reliable mechanism, which automatically resets.
