Abstract
A technique for the repair of selenium photoconductor elements is disclosed. The particular method includes applying a concentrated heat source to a damaged area of the photoconductor in an oscillating motion traverse to the damaged area so as to effect a weld of same. The oscillating motion of the heat source enables quick melting and resolidification of a minute area of selenium wihout undesirable recrystallization of the photoconductor.
Claims8
A method for repairing damaged selenium photoconductors comprising:
- applying a concentrated source of heat to a minute region of the photoconductor including a damaged area of selenium, in an oscillating motion traverse to the damage for such period of time that a weld healing of the damaged photoconductor material occurs.
