Patent CA-2007794-A1 (CA)
Inventor: MALOUIN JACQUES
IPC: G01C9/18
Filed: 1990-01-15
Abstract: FORMULE 24 ( art. 21, 31, 34 et 142 ) P R ? C I S Dans un outil de précision comme le niveau, j'ai découvert à l'utilisation, que la vision était souvent un problème. La bulle ne peut être située et vue parfaitement à cause du manque d'éclairage ambiant, de ce fait l'on a trop souvent besoin d'une source d'éclairage facultative pour que la mesure soit précise. Plusieurs utilisateurs, pour remédier aux conditions visuelles inadéquates, utilisent briquets, allumettes, lampes de poche, baladeuses et même les phares de leur véhicule. Tous ces moyens leur laissent plus souvent qu'autrement qu'une main de libre pour fixer leurs matériaux en place. La plupart du temps les deux mains sont nécessaire pour effectuer l'installation de la pièce que l'on vient de mesurer. La flamme (briquet et ou allumette) représente des risques d'incendie et des blessures aux travailleurs. Tous ces inconvénients sont résolus en incorporant un dispositif d'éclairage à l'intérieur du niveau. Ce dispositif possède quatre charactéristiques importantes. Premièrement, un couplage de lumière normale a l'extrémité de la fiole diminue grandement les reflexions parasites. Par conséquent, la bulle est parfaitement visible en toutes conditions. L'utilisateur, étant souvent pressé dans son travail peut oublier de fermer l'éclairage. Deuxiemement, de ce fait un commutateur/intérupteur électronique ( à pression de type "touch switch" ), à faible consommation d'énergie, a été développé et équipera tous les modèles afin d'éliminer le drainage des piles. Troisièmement, un capteur/chargeur solaire servira a recharger les piles lorsque l'outil ne sera pas utilisé. Le dispositif sera effectif lorsqu'il est placé sous une source quelconque de lumière . Quatriémement, le choix du niveau en forme de " torpille " représente, selon moi, la structure justifiant l'utilisation des trois charactéristiques précédentes. En effet, la majorité des utilisateurs de ce type de niveau travaillent souvent dans des endroits où il n'y a pas et ou très peu d'éclairage ambiant.

Abstract: ABSTRACT OF THE DISCLOSURE      A disc drive translation and defect management method and apparatus.  The method and apparatus includes an index table  to  translate  a  host  computer's  logical  cylinder request into an arbitrarily designated physical cylinder location  in the disc drive  system.   Once the physical cylinder is located, the physical head and sector location is determined with a quick, relatively simple mathematical translation.  If a defect is present on the indexed physi-cal  cylinder  in  question,  the  index  table provides  a defect flag and a pointer which points into a predetermined entry of a defect table.  The selected entry in the defect table provides  a defect  offset value  for the physical location in question.   The offset value is added to the physical cylinder, head and sector location to push it into a defect-free physical location.

Title: Ambulatory ladder
Inventor: KUPERMAN ARIEH
IPC: E06C5/00
Filed: 1991-04-29
Abstract: AMBULATORY LADDER -- ABSTRACT   The typical folded ladder construction used in repairing, painting. and remodeling work must be repositioned as the work progresses.  It is the purpose of this invention to provide a novel stepladder constuction with a user-powered drive.  The user-powered drive is operable by a drive arm extending from the drive and accessible to a user while aboard the stepladder.  By pumping action of the drive arm. the drive transmits rotational power to the base wheels on which the ladder is mounted, moving the ladder forward.  A steering mechanism provided on the drive arm allows the user to direct the motion of the ladder during the pumping action.  Thus, without requiring the user to dismount. the ladder may be easily repositioned by operation of the user-powered drive.  A brake mechanism is provided to lock the base wheels, preventing continued rotation once the ladder has been repositioned.  The ladder is designed for lightweight constuction, and may be folded and stored when not in use.  By virtue of its novel design. a simple, durable, practical, and lowcost ladder may be constructed for use in many applications.

Title: Semiconductor optical functional device
Inventor: ISHIKAWA TAKUYA
IPC: G02F1/313
Filed: 1991-07-09
Abstract: Provided as an optical functional device which comprises a substrate, a lower cladding layer, a waveguide layer, and an upper cladding layer each formed of a semiconductor, and in which at least one of the three layers except the substrate has a quantum well structure at a quantum confined potential. The well plane of the quantum well structure is symmetrical with respect to the center position thereof, and varies in proportion to the square of the distance from the center position.        If an electric field is applied perpendicular to the well plane , the respective changes in the absorption coefficient and refractive index in the vicinity of the absorption edge are influenced by absorption peak shifts attributable to both 1e-1hh and 1e-11h transitions. Thus, the optical functional device operates in response to both TE and TM mode light without depending on polarization.
