Patent CA-2176814-A1 (CA)
Title: Method of manufacturing crystalline microporous material
Inventor: SHIMIZU SHINICHI
IPC: C01B39/38
Filed: 1995-09-28
Abstract: A process for producing a crystalline microporous body under mild conditions using simple equipment in a highly safe state, which process is suited for producing various crystalline microporous bodies usable as adsorbents, catalysts and separating materials. The process is characterized by the use of a crystallization regulator comprising a cationic compound or an amine and the starting material containing a silicate having an ideal compositional formula of NaHSi2O5 or silicon dioxide or the use of the starting material containing silicon dioxide and an aluminum salt, and comprises the step of mixing the reactants, the step of conducting solid-liquid separation of the fine particles thus formed, and the step of crystallizing the solid component thus separted. As compared with the conventional hydrothermal synthesis process requiring such severe conditions as high temperature, pressure and alkalinity, this process is improved in safety and economy, serves to control the pore diameters arbitrarily, and gives a molded body retaining a high content of the porous structure.

Patent CA-2184310-A1 (CA)
Inventor: DOSMANN ANDREW
IPC: G01N21/78
Filed: 1996-08-28
Abstract: A diffused light reflectance readhead is disclosed. The readhead employs an improved light emitting diode (LED) providing a more strongly collimated beam of light around a beam axis onto a reagent test pad. The reagent test pad is supported on a strip guide at an angle .alpha. of 5 degrees with respect to the perpendicular of the beam axis. It has been discovered that when .alpha. is between 3 and 8 degrees that specular reflection is dramatically reduced in relation to the small reduction in reflected light received by a sensor. The diffuse reflected light travels to the sensor by passing through a staircase optical baffle at an angle of 45 degrees to the perpendicular of the beam axis. The sensor converts the optical signal into an electrical one for processing and analysis. One embodiment of the present invention can detect the presence of glucose in a blood sample.

Abstract: A modular door handle assembly has a door handle on a rotatable handle shaft mounted on a housing having a face with a bore for receiving the handle shaft. Dual-function studs retain a cover on the housing and have provision for mounting the door handle assembly to a door. Other provisions, within the housing, provide for operating a door latch in response to rotation of the door handle together with a mechanism for returning the handle to a parked position upon release of the handle from rotating force and a locking feature for releasably locking the door handle assembly to prevent operation of the door latch. The handle return and locking features are both driven by a pair of dual acting springs.          The modular design simplifies repair and replacement of the assembly.

Inventor: HILLMAN JOSEPH T
IPC: C23C16/34
Filed: 1995-04-03
Abstract: Il est possible de déposer à basse température et dans un même réacteur plusieurs couches sur un substrat de semi-conducteur. Pour obtenir une couche de nitrure de titane, on dépose d'abord par plasma CVD une pellicule de titane puis l'on crée à 25 mm de la surface un plasma qui se répartit uniformément sur la surface. La pellicule déposée peut ensuite être soumise à un recuit par un plasma d'ammoniac créé à 25 mm de la surface du substrat (28) suivi d'un dépôt par plasma CVD de nitrure de titane obtenu en créant un plasma de tétrachlorure de titane et d'ammoniac à 25 mm de la surface du substrat (28). Cela permet d'effectuer les dépôts et recuits à des températures relativement basses de moins de 800~. Lorsque du titane est ainsi déposé sur une surface de silicium, du siliciure de titane se forme sur la jonction laquelle peut ensuite être nitrurée et recouverte de titane ou de nitrure de titane en utilisant la présente invention. Le procédé objet de l'invention permet ainsi de constituer des couches multiples de titane, de nitrure de titane et de siliciure de titane sur un substrat en utilisant un même réacteur (20).

Inventor: ZEITER PATRIK
IPC: B29C51/14
Filed: 1996-12-04
Abstract: Process for manufacturing cold formed shaped forms of packaging having at least one recess from a metal-plastic laminate 20. Examples of such shaped forms of packaging are the base parts of push-through packs or blister packs. The process is such that the laminate 20 is held between a retaining tool 5 and a die 1. The die 1 exhibits at least one opening 8 and a stamp 6 is driven into the die opening 8 causing the laminate to be shape-formed into a packaging, correspondingly exhibiting one or more recesses. The die 1 and the retaining tool 5 exhibit facing edge regions 11,12 and the die 1, within the edge region 11, exhibits a shoulder region 13 that surrounds the die opening 8 or openings 8. The surface of the shoulder region 13 lies 0.01 to 10 mm lower than the surface of the edge region 11 of the die 1, and a first stamp 6 or first stamps 6 with high friction forming surface form the metal-plastic laminate in one or more steps down to 100 % of the final depth of the recess and subsequently a second stamp 6 or stamps 6 with low friction forming surface perform the final forming of the laminate 20 in one or more steps to at least 100 % of the final depth of the recess.

Filed: 1995-06-29
Abstract: An indium phosphide semiconductor substrate (10) is prepared for subsequent growth of epitaxial layers (12 to 16) to form a semiconductor device (5). In the preparation, the substrate (10) is first annealed to promote any tendency for surface accumulation of impurity atoms by diffusion from the substrate and to promote impurity atom removal from the surface of the substrate. The substrate (10) is then surface etched to remove further impurities and to provide a clean, flat surface for subsequent epitaxial layer growth. The final stage of preparation involves growing a semi-insulating buffer layer (11) on the substrate to isolate the device epitaxial layers (12 to 16) from the substrate.

Abstract: A magazine for a nail-driving tool, which may be pneumatically powered or combustion-powered, is arranged to store plural nail strips in side-by-side relation. A spring biased mechanism is used to bias the stored strips toward a side rail. Being movable along a frame between an advanced position and a retracted position, a feeding member in the retracted position engages the shank of an endmost nail of the stored strip nearest to the side rail. A negatorspring mechanism biasing the feeding member toward the advanced position includes a spring leaf arranged to be longitudinally pulled between the nail heads of the stored strip nearest to the side rail and the nail heads of the next strip when the feeding member is moved from the advanced position into the retracted position. The feeding member has a wedging portion arranged to push between some of the nail shanks of the stored strip nearest to the side rail of the magazine and some of the nail shanks of the next strip and to lead the spring leaf when moved from the advanced position into the retracted position and a rail-engaging portion arranged to push between the side rail and some of the nail shanks nearest to the side rail when moved similarly. In an operative position, in which it can be releasably latched, a biasing member bears against the nearest strip. A floor member can be adjustably positioned. When latched, the biasing member latches the floor.
