Patent CA-2000030-A1 (CA)
Title: Adhesion layer for platinum based sensors
Inventor: JOHNSON ROBERT G
IPC: G01F1/684
Filed: 1989-10-02
Abstract: ABSTRACT OF THE DISCLOSURE        The marginal adhesion of platinum to silicon nitride is a serious issue in the fabrication of microbridge mass air flow sensors.  High temperature stabilization anneals (500-1000°C) are necessary to develop the properties and stability necessary for effective device operation.  However, the annealing process results in a significant reduction in the already poor platinum/silicon nitride adhesion.          Annealing at relatively high temperatures leads to the development of numerous structural defects and the production of non-uniform and variable sensor resistance values.  The use of a thin metal oxide adhesion layer, approximately 20 to 100 angstroms in thickness is very effective in maintaining platinum adhesion to silicon nitride, and through the high temperature anneal sequence.  Moreover, incorporation of the thin metal oxide adhesion layer minimizes the development of structural defects, and results in significantly improved uniformity and control of platinum sensor/heater resistance characteristics.

Filed: 1989-11-22
Abstract: ABSTRACT:    The assembly comprises a first insulating housing having terminal receiving through cavities each having therein a resilient locking lance, and a second insulating housing having through cavities. There projects from the front face of the second housing a row of locking lance actuating tongues.  In a terminal loading position of the housings the front face of the second housing is spaced from the front face of the first housing so that each tongue projects to some extent beneath a respective locking lance.  In this loading position, an electrical terminal connected to a lead is inserted through each cavity of the second housing into a cavity of the first housing.  The housings are then moved relatively towards one another into a terminal locking position, so that each tongue is advanced further beneath the corresponding lance to lock the terminal in the cavity.  Pawl and ratchet means are provided on the housings for locating them in their loading and locking positions.

Title: Lamp package with an integral strut
Inventor: OLDHAM EDWARD H
IPC: B65D5/50
Filed: 1990-07-20
Abstract: This invention relates to a package which is suitable for the packaging of fragile articles such as electric light bulbs. The package is especially adapted far high speed packaging in that the package may be collapsed to a flat blank for shipping but may be quickly opened in such a manner that each of the opposing sidewalls of the package has a projecting tab extending inwardly therefrom so that the two tabs are joined together to form an integral strut and thus stabilize the two opposing sidewalls of the package.      Because of the symmetry of the devices being packaged the projecting tabs must be symmetrically located in a central area of the sidewalls. It will be found that this invention will be applicable to high speed packaging of fragile articles in chipboard cartons which are capable of receiving at least two similar articles such as lamp bulbs.

Title: Reclosable mechanical fastener based on a composite article
Inventor: LU SHIH-LAI
IPC: B29C71/04
Filed: 1990-10-01
Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to reclosable mechanical fasteners and to a method of making a reclosable mechanical fastener. A widely used quick  lose/quick release reclosable mechanical fastener is the "Velcro" hook and loop fastener, available from Velcro USA, Inc., Manchester, New Hampshire. These fasteners have several disadvantages.  For example, when these fasteners are used with washable articles of clothing, the hook portion of the fasteners tends to snag the fabric during washing. Moreover, the hook and loop portions of the fasteners tend to collect lint.  The cost of hook and loop fasteners is sufficiently high to increase the cost of an article of clothing.  These types of fasteners are not easy to manufacture.  This invention provides a reclosable mechanical fastener comprising a fastening component having a surface structure by which two such fastening components can become releasably attached. The novel fastening component is a composite of a tough substrate and a fastening layer that forms said surface structure, which fastening layer is formed from a cured oligomeric resin composition having one or more like or different hard segments, one or more like or different soft segments, and one or more like or different monovalent moieties containing a radiation-sensitive, addition-polymerizable, function group.  The novel fastener forms stronger linkages than were possible with similar fasteners of the prior art.
