Title: In-line rotary inserter
Inventor: FALLOS GEORGE
IPC: B65B51/10
Filed: 1990-04-12
Granted: 2003-11-18
Abstract: An in-line rotary inserter device comprises an envelope feed station and insert feeding modules, an inserting station, a sealing and stacking assembly, and various diverters. The envelope feed station withdraws envelopes from a hopper-held envelope stack and conveys them to the inserting station. Each insert feeding module comprises a hopper-held insert stack disposed above, along, and in line with an insert conveyor. The conveyor, along its track, carries inserts dispensed from the hopper-held insert stacks to the inserting station. Diverter stations for diversion of envelopes and inserts in various locations along their feed paths are provided for normal operational purposes and for rectification of sensed fault conditions. Subsequently to inserting, insert-filled envelopes are conveyed from the inserting station, are sealed, turned, stacked, and processed through operations that are customary in preparation of mailable items. Supervision and coordination of operation of the various assemblies and stations in concert is provided by computer control.

Abstract: Abstract of the Disclosure A method of connecting a waveguide substrate made of electro-optical crystal and an optical fiber by means of a bonding agent of the ultraviolet light curing type is disclosed.  According to the method, first, a reflection preventing film with an ultraviolet light intercepting function of passing therethrough light of a wavelength to be transmitted by way of the optical fiber but intercepting ultraviolet rays of a wavelength with which a bonding agent is to cure is formed on an end face of a waveguide substrate.  Then, an end face of the optical fiber is closely contacted with the reflection preventing film with the bonding agent applied to the end face of the optical fiber, and ultraviolet rays are irradiated upon the end face of the waveguide substrate from the side on which the reflection preventing film is formed to cause the bonding agent to cure.  Also detailed layer structures of such reflection preventing film with an ultraviolet light preventing function are disclosed.
