Patent EP-0108735-A3 (EP)
IPC: F41G1/14
Filed: 1983-11-02
Abstract: An optical aiming device with a front sight (1) and a rear 
sight (3). The front sight is in the form of an upstanding 
needle-like element or an illuminated fine spot. To prevent 
repeated accommodation movements of the lens of the eye 
during aiming of the weapon the rear sight comprises two 
prisms (4, 5) disposed at each side of the front sight (1). Each 
prism will produce an image of the front sight, said image 
lying at the same distance from the shot's eye as is the 
eye-front sight-distance.

Abstract: A decoupling capacitor is presented including a pair of 
conductors (14, 16), each having a lead connected thereto 
formed from a continuous strip of electrically conductive 
material (10) (lead frame), the strip having opposing planar 
surfaces. A pair of dummy leads (30, 36), each being 
associated with a conductor, but isolated therefrom, is also 
formed from the strip. Thereafter, a strip (42) of first 
insulating material is positioned across from one opposing 
surface of the conductive strip and a strip (44) of second 
insulating material having a plurality of openings or win­
dows (50) therein is positioned on the other opposing 
surface of the conductive strip. The two insulating layers (42, 
44) sandwiching the conductive strip are then heat tacked 
and hot press laminated to form a continuous strip of 
laminated material. The windows are positioned on the 
conductive strip to define access opening for the two 
conductors. Next, drops of solder paste (54) are deposited on 
each conductor through the windows (50) whereupon a 
multi-layer monolithic ceramic capacitor (56) is placed 
through each window, between the two conductors (14, 16) 
and in contact with the solder paste (54). The multi-layer 
capacitor (56) includes first and second conductive end 
surfaces (62) which are electrically and mechanically bonded 
respectively to each conductor (14, 16) via the solder (after a 
reflow process). The multi-layer capacitor is then encapsu­
lated and sealed by placing encapsulant material (64) (i.e., 
epoxy, silicon, etc.) in the space defined by the window (50). 
Finally, the now sealed, laminated and encapsulated decou­
pling capacitor is severed from the lead frame (10). The 
decoupling capacitor of the present invention will thus be 
both hermetically sealed and automatically insertable for use 
in conjunction with integrated circuit DIP inserter devices.
