Title: Optical coupler
Inventor: KIMURA HIROYUKI
IPC: G02B6/42
Filed: 1990-11-26
Abstract: PURPOSE:To make it unnecessary to change the specification for each optical fiber to be used by coupling an optical fiber and a photosensitive or a light emitting element through a guide beam fiber in the same diameter as the narrowest fiber among those connected with an optical coupler. CONSTITUTION:A guide beam fiber 5 consisting of a core 5a and clad 5b is provided between a housing 2a and an optical connector coupler 2b and positioning should be made with a spacer so that the core 5a and an optical fiber 4 are aligned on the same axis. Moreover, as a fiber 5, the narrowest fiber among the optical fibers connected to an optical coupler 20 is used. Therefore, when the fiber 4 is coupled with an optical element 2 by the optical coupler 20, the optical element 1 is coupled with the end face of the fiber 5 without relation to the core diameter 4a and the coupling coefficient can substantially be kept constant without relation to the core diameter of connected fiber 4.

IPC: H04N1/32
Filed: 1989-12-13
Abstract: PURPOSE:To prevent a line disconnected due to the reception of an echo by collating the coincidence/noncoincidence of a signal transmitted from its own equipment with a following reception signal and setting the reception waiting state of an original signal from opposite equipment again when the coincidence is obtained. CONSTITUTION:When the transfer of a signal is performed between facsimile equipment, a first FAX message is transmitted from a transmitter T side, and furthermore, after a multi-page signal MPS or procedure interruption MPS (PRI-MPS) being outputted, a response signal waiting state is set. When a certain response signal is received. it is collated whether the response signal is the multi-page signal MPS or the procedure interruption MPS(PRI-MPS), and when they are the same signals i.e., an echo signal, an original response signal from a receiver R is set at a receptable state again. Therefore, it is possible to precisely perform the transmission of a document even on a communication channel with the echo with high signal level or delay quantity.
