Title: Injection molded parts having improved surface gloss
Inventor: LEE BIN
IPC: C08J9/30
Filed: 1998-01-19

Title: Breath-powered mist inhaler
Inventor: VOLGYESI GEORGE
IPC: A61M11/06
Filed: 1998-01-26
Abstract: A breath-powered inhalation device is disclosed comprising a hollow cylindrical body having an air inlet at one end and an air outlet at another end. The air outlet is narrowed so that air velocity increases as air moves through the outlet. At the air outlet is positioned a releasing mechanism which preferably comprises a fibre tip impregnated with a medicament or the like. As the air rushes past the releasing mechanism, the medicament or the like is atomized and carried into the respiratory tract of the user by the air. The breath-powered inhalation device of the present invention provides advantages over conventional inhalation devices using compressed gases as propellants since it is more compact, simpler and does not require synchronization of activation of the device and inhalation by the user.

Patent CA-2231102-A1 (CA)
Inventor: SCHULZ HARALD
IPC: E06B3/263
Filed: 1996-09-05
Abstract: L'invention a pour objet un profilé composite utilisé comme isolant thermique, présentant une traverse isolante (6) deux parois de limitation (6.1, 6.2) sensiblement parallèles, formant un espace creux entre elles. Ces parois peuvent être réunies entre elles par au moins une entretoise (10). En partant d'une épaisseur de paroi s = 0,5 mm et d'une conductibilité thermique lambda = 0.35 W/mK des parois de limitation (6.1, 6.2), la largeur (D) de la traverse isolante est déterminée comme étant égale, respectivement, à 20 mm, lorsqu'on cherche à obtenir une résistance d'isolation comprise, pour cette traverse isolante, entre 0.15 m?2¿K/W et 0,30 m?2¿K/W, à 30 mm, pour une résistance d'isolation de 0,25 m?2¿K/W à 0,50 m?2¿K/W, à 40 mm, pour une résistance d'isolation de 0,35 m?2¿K/W à 0,65 m?2¿K/W, à 50 mm, pour une résistance d'isolation de 0,40 m?2¿K/W à 0,80 m?2¿K/W. La largeur (d) de l'espace creux ou chambre creuse est alors inférieure ou égale à la largeur (D) de la traverse isolante, et supérieure ou égale au tiers de la largeur (D) de cette traverse, pour autant que la hauteur de cet espace ou de cette chambre (11) soit inférieure ou égale à 5 mm. Pour une hauteur de l'espace creux ou de la chambre creuse supérieure à 5 mm et jusqu'à 20 mm, et avec au moins une entretoise (10), le rapport de la hauteur (h) à la largeur (d) est supérieur ou égal à 0,2 et inférieur ou égal à 5. Lorsque l'épaisseur de paroi (s) varie entre 0,25 et 1,0 mm, il y aura lieu de tenir compte, pour la variation de la résistance d'isolation en fonction de l'épaisseur de paroi (s), conformément à la relation R(s)=R(s=0,25 mm)+(s - 0,25)/0,25 * delta R, d'une valeur delta R comprise entre 0,025 et 0,05. Un accroissement de la conductibilité thermique des parois (6.1, 6.2) de 10 % dans un intervalle compris entre 0,15 W/mK et 0,40 W/mK entraîne une diminution de la résistance d'isolation de 2 à 4 %, dont on tiendra compte en fonction des grandeurs initialement choisies.

Inventor: NAZZAL GREG
IPC: E21B47/024
Filed: 1997-08-08
Abstract: The method and apparatus of the present invention allow the creation of a window in casing downhole using explosive techniques. Locating stakes (10) are initially placed and subsequently surveyed for their depth and orientation. The window-cutting tool locates itself on one of the stakes, and the explosive charges are oriented with respect to the lug downhole so that when the tool is fired, the cuts are made with the appropriate orientation at the proper depth. In the preferred embodiment, horizontal cuts are made, followed by vertical cuts. The tool has the capability of positioning itself adjacent the casing which is to be explosively cut. The strips that are created after the horizontal and vertical cuts are concluded are fished out using a variety of alternative techniques. Another locating or orienting lug, which has been initially installed, can subsequently be used to locate and orient an anchoring device for a whipstock so that the sloping face of the whipstock is pointed directly at the window that has just been explosively cut.

Filed: 1996-12-16
Abstract: A pipe connector has a coupling (22) with a first cylindrical land (34), a second cylindrical land (36), and a third cylindrical land (38). There is a first annular recess (42) defined between the first cylindrical land (34) and the second cylindrical land (36), and a second annular recess (44) defined between the second cylindrical land (36) and the third cylindrical land (38). A gate channel (50) communicates between the two recesses (42, 44) through the second cylindrical land (36).      Circumferential seals (46, 48) extend around the first and third cylindrical lands (34, 38).      A cement injection port (52) communicates between the outside of the connector of the first recess (42), and a cement vent port (54) communicates between the outside of the connector and the second recess (44). In use, a pipe (24) is inserted into the coupling to rest upon the three lands (34, 36, 38), and cement is forced into the injection port (52). The cement flows circumferentially around the first annular recess (42), through the gate opening (50), circumferentially around the second annular recess (44), and out through the vent port (54). The seals (46, 48) prevent the cement from flowing out of the interior of the connector.

Title: Multidirectional time-division multiplexing wireless data communications system
Inventor: SHIMADA HIDEAKI
IPC: H04J3/00
Filed: 1999-01-18
Abstract: A multidirectional time-division multiplexing wireless data communications system can prevent erroneous data from being transmitted through a data communications line even when a bit error has occurred in transmission data through interference, etc. occurring in a wireless area. An error correcting redundant bit, obtained by performing an error correcting code operation by an error correcting code circuit on a low-speed continuous signal, is multiplexed to a specific vacant slot in a wireless frame. A burst signal, converted by a continuous/burst signal conversion circuit through an interleaving operation, is multiplexed to a predetermined time slot, and transmitted to a wireless area. The burst signal is received by the burst/continuous signal conversion circuit, and converted into a continuous signal through a de-interleaving operation. A division circuit divides an error correcting code to generate a syndrome. Based on the syndrome, an error position detection circuit specifies bit error position in data, and an addition circuit corrects errors.

Title: Naphthalene derivative and liquid crystal composition comprising the same
Inventor: NEGISHI MAKOTO
IPC: C07C255/50
Filed: 1999-04-21
Abstract: Disclosed is a novel liquid-crystalline compound which is a naphthalene derivative useful as an electro-optical liquid crystal display material, a liquid crystal composition containing such naphthalene derivatives and a liquid crystal display device comprising the same. The naphthalene derivative provided by the present invention exhibits an excellent liquid-crystallinity and miscibility with currently widely used liquid crystal compositions or compositions. The addition of the naphthalene derivative makes it possible to drastically lower the threshold voltage of the liquid crystal composition while maintaining its high response. The naphthalene derivative of the present invention is characterized by a large birefringence index.  Further, most of the naphthalene derivative of the present invention has no strongly polar group in its molecule and thus can also be used for active matrix driving. Moreover, as shown in the foregoing examples, the naphthalene derivative of the present invention can be easily produced and is colorless and chemically stable. Accordingly, the liquid crystal composition comprising tha naphthalene derivative of the present invention is extremely useful as a practical liquid crystal composition, particularly a liquid crystal composition which can operate within a wide temperature range and requires a high speed response and a low voltage driving.
