Abstract
Abstract A means and method for removably operably connecting a light conducting and directing filament means of small diameter (in the order of 0.005 to 0.020 inches) with a limited or minute lightsensitive area on a photoconductive element such as a phototransistor or photodiode in order to direct and register a maximum amount of radiant energy such as light on the lightsensitive area. The connecting means and method provides precise positioning and holding of an end face of a filament means in spaced relation to the light-sensitive area while permitting removal of the filament means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
Means for connecting a light-conducting means with respect to a light-sensitive area on a photoelectric means to precisely direct conducted light thereon, comprising in combination: a photoelectric means including a light-sensitive surface lying in a plane; means for directing and conducting light from a remote source onto such surface; said light-conducting means including a single filament means having an exit face lying in a plane spaced from and parallel to said light-sensitive surface and defining a space therebetween; means for positioning and holding said filament means with its exit face in light transfer relationship to said light sensitive surface; clear light-transmitting material means surrounding and shielding said exit face and said light-sensitive surface at said space; and means for removing said filament means and its exit face from said spaced light transfer relationship with respect to said light-sensitive surface.
Claim 2
Dependent Claim
139 words
Means for connecting a light-conducting means with respect to a light-sensitive area on a photoelectric means to precisely direct conducted light thereon, comprising in combination: a photoelectric means including a light-sensitive surface lying in a plane; means for directing and conducting light from a remote source onto such surface; said light-conducting means including a single filament means having an exit face lying in a plane spaced from and parallel to said light-sensitive surface and defining a space therebetween; means for positioning and holding said filament means with its exit face in light transfer relationship to said light sensitive surface; clear light-transmitting material means surrounding and shielding said exit face and said light-sensitive surface at said space; and means for removing said filament means and its exit face from said spaced light transfer relationship with respect to said light-sensitive surface.
Claim 3
Dependent Claim
31 words
In a means as stated in claim 1 wherein said positioning and holding means includes a seat for one end of said filament means formed in said clear light-transmitting material means.
Claim 4
Dependent Claim
43 words
In a means as stated in claim 1 wherein said positioning and holding means includes a holder member having a throughbore to receive said single filament means; and attachment means adjacent said exit face for securing said holder member to said photoelectric means.
Claim 5
Dependent Claim
37 words
In a means as stated in claim 3 wherein said attachment means includes an outer mass of opaque material surrounding such light sensitive surface, said light-transmitting material means, and at least a portion of said holder member.
Claim 6
Dependent Claim
41 words
In a means as stated in claim 3 wherein said releasable, frictional securement means includes a cap member having an opening aligned with said throughbore; And means between said cap member and said holder member for frictionally holding said filament means.
