Title: Frequency stabilization of a laser beam by using a birefringent body
Inventor: SHIBUTANI MAKOTO
IPC: H04B10/564
Filed: 1990-08-30
Abstract: ABSTRACT OF THE DISCLOSURE     To supply a frequency control signal to a laser diode module for generating a laser beam susceptible to a variation in frequency or wavelength, a frequency stabilizing device comprises a birefringent body (21) for converting the variation to a variation in a polarization state of the laser beam to produce a polarization varied beam, which a polarization separating element (22) separates into first and second beam components having orthogonally polarized directions and first and second beam intensities.  Optical detectors (26,27) detect the beam intensities to produce first and second detection signals.  A subtracter (28) calculates a difference between the beam intensities.  A control signal producing arrangement (29) produces the frequency control signal in compliance with the difference.          Preferably, the difference is normalized by a sum of the beam intensities.  The birefringent body may be a uniaxial or a biaxial body.  The uniaxial body should have an optic axis which forms an angle of 45° with a predetermined plane of polarization of the laser beam.  In this event, the orthogonally polarized directions should be parallel and perpendicular to predetermined direction of polarization.          It is possible to use the sum in stabilizing an output power of the laser diode module.

The sticking material is adhered  weakly at a portion of the first heat adherent resin layer and is adhered strongly at the portion of second heat adherent resin layer.          Therefore, the base material is not accidentally peeled off from the postcard material with a force applied to the second heat adherent resin layer.    When peeled off the base material at the portion where the second heat adherent resin layer is not formed, the base material are peeled off from the postcard material  in the postcard material including the base material having the suppressiveness, while, the base material, the suppression layer, and the first heat adherent resin layer are peeled off from the postcard material in the postcard material including the suppression layer having the supprssiveness.  Therefore, the surface of the postcard material can be seen.    According to the present invention, a sticking material which is able to cover preferabley and temporarily the surface of the postcard material without any process on the surface of the postcard material, and a manufacturing method thereof are obtained.

Abstract: FLUIDIZED BED STEAM TEMPERATURE ENHANCEMENT SYSTEM                ABSTRACT OF THE DISCLOSURE    A reactor in which a furnace and a heat recovery area are provided.  A bed of solid particulate material including fuel is supported in the furnace and air is introduced into the bed at a velocity sufficient to fluidize same and support the combustion or gasification of the fuel.  The products of combustion (or flue gases) pass upwardly through the furnace and transfer heat energy to the walls thereof to produce steam.  Flue gases leaving the upper region of the furnace section are transported to a heat recovery area, which functions to remove additional heat energy from the flue gases for producing the steam.          A flue gas by-pass system is provided which transports relatively hot flue gases from a lower region of the furnace section to the heat recovery area for improving isothermal operating conditions and optimizing reactor performance.  One or more conduits pass flue gases directly from selected extraction points within the lower region of the furnace to an upper portion of the heat recovery area.  A dust collector may be connected to the gas extraction conduits for separating particulate material from the flue gases, if needed.     ld-4906s

Title: Air-floated apparatus
Inventor: FASSAUER ARTHUR L
IPC: A47L9/00
Filed: 1990-08-17
Abstract: An air-floated apparatus, such as a lawn mower, is comprised of an endless housing (12) having a bottom opening defined by a relatively flat plate member (42) projecting inwardly from around substantially the entire bottom part of the housing (12). At least one air impeller (14) is provided for pressurizing air within the housing (12) sufficient to float the housing above a support surface. The plate member (42) directs air laterally into the housing (12) to inhibit the escape of air from the housing (12) and maintain a relatively constant pressure in the housing (12). The rotary action of the lawn mower cutting blade (16) centrifuges grass cuttings within the housing. The plate member (42) acts as a shelf to support the centrifuged grass cuttings and cooperates with an inner wall (38) of the housing (12) to direct the grass cuttings into a discharge duct (30) for collection in a bag or other receptacle.
Patent CA-2039856-A1 (CA)
Inventor: BOHON WILLIAM M
IPC: F04B9/02
Filed: 1991-04-05
Abstract: ABSTRACT The present invention provides a method and apparatus for eliminating at least a portion of the energy losses in a well pumping system which are due to "regeneration" (i.e. those periods during the pumping cycle in which the pumping system experiences negative net torque). This is accomplished by positioning a clutch means in the driving connection between the prime mover and the pumping unit of the well pumping system so that the clutch means forms a driving connection between said prime mover and said pumping unit during periods when said pumping unit experiences positive net torque and but effectively disengages the driving connection between said prime mover and said pumping unit to allow freewheeling therebetween during periods when said pumping unit experiences negative net torque.

Title: Endarterectomy catheter and method of use thereof
Inventor: HALLIBURTON ALEXANDER G
IPC: A61B17/22
Filed: 1991-06-03
Abstract: An   endarterectomy   catheter   for   removing obstructions  from an artery comprises  a  cylindrical housing, the housing having an opening across which a primary shear is movable. The primary shear is razor sharp and cylindrical and movable by means of a cable and trigger backward and forward within the housing to excise obstructions that protrude into the opening. A guide wire positions the catheter in an artery.         The edge of the housing at the opening may be sharp to grip the obstruction and to assist in the cutting action of the primary shear. The shear is hollow and  collects  debris  from  the  excised  obstruction. Openings in the housing allow blood to pass through the body.     A method of removing obstructions from an artery includes  locating  a  housing  in  an  artery  with  an obstruction protruding into an opening in the housing, moving a razor sharp cylindrical shear across the opening to excise the obstruction,  encapsulating the excised obstruction in the housing, and removing the housing from the artery.

Title: Sucette a medicament
Inventor: CANTIN MARCEL
IPC: A61J7/00
Filed: 1991-07-02
Abstract: SUCETTE ? MEDICAMENT PRÉCIS Les instruments d'usage courant pour administrer un médicament à un jeune enfant ne lui sont aucunement familiers et crée de la part de l'enfant une réticence naturelle qui nuie à l'administration d'un médicament. Dans la présente invention le médicament est administré à l'aide d'un instrument qui a la forme d'une sucette, mais dont la sucette est trouée devenant ainsi une tétine qui permet à l'enfant de téter le médicament. La sucette comporte de plus un réservoir pour emmagasiner une quantité suffisante de médicament correspondant à une dose usuelle de médicament. MÉMOIRE DESCRIPTIF La présente invention se rapporte à une sucette utilisée pour administrer un médicament à un enfant. Donner un médicament à un enfant n'est jamais chose facile. En bas âge, alors que l'enfant est malade, il recherche l'attention d'autrui et la présence d'objets familiers. L'approche pour administrer un médicament à un enfant a toujours été jusqu'à aujourd'hui d'utiliser des outils d'absorbtion auquels l'enfant n'est aucunement familier, tel seringue ou cuiller en plastique graduée.
