Title: Blade structure in a gas turbine
Inventor: ITO EISAKU
IPC: F01D5/14
Filed: 2002-01-11
Granted: 2006-05-09
Abstract: In the blade structure in a gas turbine, inlet included angles are made large. As a result, a curve of a relative relationship between incidence angles icl and isl and pressure loss becomes mild. Entrance metal angles, which are formed by an axial direction of the gas turbine and a tangential direction to a camber line at the front edge of the stationary blade, are made small. As a result, it becomes possible to make the incidence angles small.      Chord length of a tip portion of a moving blade is made large. As a result, it becomes possible to make small the deceleration on a rear surface of the tip portion of the moving blade. Accordingly, it becomes possible to make the pressure loss small, and therefore, it becomes possible to improve the turbine efficiency.

Abstract: The present invention provides a method and apparatus for selectively destroying dividing cells in living tissue formed of dividing cells and non-dividing cells. The dividing cells contain polarizable intracellular members and during late anaphase or telophase, the dividing cells are connected to one another by a cleavage furrow. According to the present method the living tissue is subjected to electric field conditions sufficient to cause movement of the polarizable intracellular members toward the cleavage furrow in response to a non-homogenous electric field being induced in the dividing cells. The non-homogenous electric field produces an increased density electric field in the region of the cleavage furrow. The movement of the polarizable intracellular members towards the cleavage furrow causes the break down thereof which results in destruction of the dividing cells, while the non-dividing cells of the living tissue remain intact.

Title: Process to manufacture high impact natural composites
Inventor: SAIN MOHINI M
IPC: C08J5/04
Filed: 2002-10-26
Granted: 2011-02-01
Abstract: The use of natural fibers as reinforcing filler in thermoplastics is a relatively new innovation and has great potential to replace glass fiber products in building, consumer goods, furniture and automotive industry. Our published results demonstrated that laying natural fiber mat and polymer film in a definite pattern and orientation can enhance mechanical strength. In this invention, a unique process has been developed to manufacture high impact strength composite that contains loose natural fiber and/or a combination of loose natural fiber and natural fiber mat to develop green composites outstanding impact strength and other mechanical properties. Loose fibers used in this process can be obtained from agro-plant and wood. Mats, if used, can be obtained from similar sources. Polymer those are used include thermoplastic polyolefins (TPOs), acrylic and polyester films. This invention is especially useful for natural composites with natural fiber content above 40% by weight up to 93 wt% fiber. Film stacking and fiber spraying methods were used to construct sheet, laminates and thermoforming and compression molding were used to design a product. A range of impact strength was obtained which varies from 100 J/m to as high as 250 J/m with a significant increase in flexural and tensile strengths. Products having uniform density profiles yield maximum enhancement in impact properties.

Title: Circuit de polarisation maintenant constante la valeur du rapport entre transconductance et capacite de charge
Inventor: BAZARJANI SEYFOLLAH
IPC: G05F3/08

Granted: 2009-05-26
Abstract: L'invention concerne un circuit de polarisation (126) destiné à polariser un amplificateur opérationnel (110), afin de maintenir constante la valeur du rapport entre transconductance et capacité de charge (c'est-à-dire une valeur constante g¿m?/C¿L?), malgré les variations de température, de processus et les effets de variation de substrat. Le circuit de polarisation (126) comprend une paire de sources de courant et un circuit de résistance (SC) équivalant à un condensateur commuté (136) qui établit une résistance équivalente entre les sources de courant. Le fait de mettre en place le circuit de résistance équivalant à un condensateur commuté, synchronisé par des signaux d'horloge fixes sans chevauchement, permet de maintenir une valeur sensiblement constante g¿m?/C¿L? du circuit de polarisation. On maintient ainsi une largeur de bande fixe dans l'amplificateur opérationnel polarisé. En association avec les amplificateurs opérationnels d'un circuit à condensateur commuté, la largeur de bande constante permet à ce type de circuit de fonctionner à une vitesse de commutation constante malgré les variations de température et de processus. De plus, en plaçant le circuit de résistance équivalant (136) à un condensateur commuté entre les sources de courant du circuit de polarisation, on élimine les différences de tension entre les sources, ce qui supprime tout défaut d'adaptation de tension de seuil, et on compense les variations des effets de substrat.
