Patent CA-2043760-A1 (CA)
Title: Method of producing corrugated metal sheeting and method of producing honeycomb structure therefrom for carrying catalystic agents used for purifying exhaust gases
Inventor: MINAMIDA KATSUHIRO
IPC: F01N3/28
Filed: 1991-06-03
Abstract: A method produces a corrugated metal sheeting including a flat metal sheet and a corrugated metal sheet joined to each other, which sheeting is used to produce a carrier or honeycomb structure for carrying catalystic agents used for purifying exhaust gases from, for example, an internal combustion engine of an automobile.  In the method, the flat and corrugated metal sheets are brought together so that corrugations of the corrugated metal sheet are successively brought into contact with the flat metal sheet in such a manner that the corrugated metal sheet is freely movable to thereby release resilient stresses therefrom, and a laser beam is incident on a contact line between the flat metal sheet and each of the corrugations of the corrugated metal sheet, to thereby weld them to each other.

Patent CA-2047224-A1 (CA)
Title: Structural member
Inventor: LEWIS SIMON J
IPC: E04C3/07
Filed: 1990-12-04
Abstract: ABSTRACT     A composite structural member (10) is fabricated by springing together two generally 'C' section components (11), each of which has a web (12) with a pair of ribs (16) extending along it, upper and lower main flanges (13) terminating at their edges in sub-flanges (14) directed towards each other, and each sub-flange terminates in a lip (15a, 15b) which is directed back towards the web (12).  The lips (15a, 15b) of each component engage respectively outer and inner surfaces of the ribs (16) of the other component, thereby inhibiting displacement of contiguous flanges (13), and maintaining a high moment of inertia which inhibits excessive deflection of the member  (10) under load.

Patent CA-2056272-A1 (CA)
Title: Combined range laser scanner
Inventor: SALATTO PATRICK JR
IPC: G02B26/10
Filed: 1991-11-27
Abstract: A combined range laser scanner and method for electro-optically reading indicia such as bar codes having parts of different light reflectivity which utilizes two laser diode optical illumination systems optimally focused for different working ranges. A first laser illumination system is optimized for contact operation and has a range extending to approximately two feet. The second laser illumination system is optimized for longer range scanning from approximately two to seventeen feet, and the two laser scanning systems are integrated into one combined range laser scanner. The combined range laser scanner incorporates therein logic circuitry which enables either laser illumination system as required fro the particular scanning application. Depending upon which laser illumination system is selected, the laser spot speed (e. g. amplitude of the drive signal for the scanning motor) is controlled to limit the frequency of received light signals to that of standard signal processing and decoding circuits. scanning is achieved with a common oscillating mirror element driven by a scanning motor, and the amplitude of the applied scanning motor driving signal is greater for the first laser illumination system optimized for contact or short range operation and less for the second laser illumination system for longer range scanning.

Title: Optical disk substrate, method for initialization thereof and driving apparatus for initialization of said optical disk
Inventor: MINODA TAKESHI
IPC: G11B20/12
Filed: 1992-03-27
Abstract: ABSTRACT      There are provided an optical disk substrate formatted according to the zone formatted system, method for initialization thereof, and driving apparatus for initialization of the optical disk.  The optical disk substrate is initialized while at least one track in the vicinity of the inner peripheral side and/or the outer peripheral side in the radial direction of the boundary between an optional zone and another zone situated on the outer peripheral side is left unused as a recording area.  By virtue of this construction, at least one of the tracks having a high possibility of bringing about the pit shift or double transfer is left unused as a recording area.   Accordingly, the information stored in a recording area can be read out without being influenced by the occurrence of the pit shift or double transfer, and thus it is possible to get rid of the occurrence of a burst error caused by such pit shift or double transfer.

The resulting binderless shaped article is then heated at 800 ·C for a period of time sufficient to completely remove the whiskers or fibers from the shaped articles. The article is then encapsulated in glass and hot isostatically pressed at a pressure of 30,000 psi to densify the article to approximately 99 % of theoritical. The resulting article has a complex geometry and a large cross-section but without detrimental cracks.
