Title: Optical waveguide component and a manufacturing method therefor
Inventor: OHTA TOSHIHIKO
IPC: G02B6/30
Filed: 1993-10-06
Abstract: ABSTRACT OF THE DISCLOSURE    Provided is an optical waveguide component which has end faces to be connected with optical fiber connectors by means of guide pins, comprising an optical waveguide component body formed having an optical waveguide core portion, and a resin mold portion covering all the faces of the optical waveguide component body except the end faces, each end face of the resin mold portion being formed having guide pin holes with the optical waveguide core portion used as a positioning reference.  Since the guide pin holes for connection with the optical fiber connectors are formed in the resin mold portion which covers the optical waveguide component body, the guide pin holes and a substrate can be restrained from being broken even though they are subjected to a load after connection.     Marker portions for the arrangement of the guide pins, unlike conventional ones, need not be deep grooves in the upper surface of a cladding portion. Even in the case of a component whose optical waveguide core portion has a two-dimensional pattern, therefore, the marker portions can be formed without cutting the core pattern into pieces.

Patent CA-2124606-A1 (CA)
Inventor: STONE MAUREEN C
IPC: G06F17/30
Filed: 1994-05-30
Abstract: A method is disclosed for operating a processor-controlled machine to produce a composite view of an original, or first, image by combining the functions of multiple viewing operations and using the model data structure from which the first image was produced (called the "FIMDS".) A first viewing operation region (1VOR) in a first viewing position in the display area of the display device has displayed in the 1VOR a second image produced according to a first viewing operation (VO1), associated with the 1VOR, that maps the FIMDS to image definition data defining the second image. Request signal data is received from a signal source to present a second viewing operation region (2VOR) in the display area coextensive with at least a portion of the 1VOR, forming a composite viewing operation region in the overlapping region. The 2VOR has a second viewing operation (VO2) associated with it for mapping an input model data structure, typically but not necessarily the FIMDS, to image definition data defining a second image for display in the 2VOR (2VOR-SI), providing an alternate view of the FIMDS that is different from that provided by the VO1 associated with the 1VOR. In response to the request signal data, a composite viewing operation, composed from the functions of the VO1 and the VO2, maps the FIMDS to image definition data defining a composite image for display in the composite viewing operation region substantially at the same time as the first image is being displayed in the display area. This gives the perception to the machine user of applying composed viewing operations to information presented in the original image.

Title: Resequence method and resequencing device realizing such a method
Inventor: PESCHI ROBERT N L
IPC: H04L49/111
Filed: 1994-06-28
Abstract: ABSTRACT         The resequencing device resequences information packets of an information stream transmitted from a transmitter station (IWU1) to a receiver station (IWU2) over a network (SMDS).  This information stream includes first packets which may be received in the receiver station out of sequence with respect to each other or with respect to second packets which are always received in sequence. The network is for instance a Switched Multimegabit Data Service network where the first packets have a group address and are transmitted from the transmitter station to the receiver station and to other receiver stations (IWU2, IWU3) belonging to the same group, and the second packets have an individual address and are transmitted from the transmitter station to the receiver station.          The transmitter station includes a counter circuit (C1) providing a counter value and a processing circuit (P1) which assigns the counter value to the second packets and the counter value incremented by one to the first packets.          In this way the sequence numbers of the first packets form an ascending monotonous series and the second packets have sequence numbers equal to the sequence number of the preceding first packet.  Based thereon the packets can easily be resequenced by a second processing circuit (P2) located in the receiver station, and which therefor uses a second counter circuit (C2), a timer (T) and a buffer (B).
