Title: Couvercle chauffant electrique
Inventor: AFSANEH MAHYARI
IPC: A47J37/10
Filed: 2002-06-27
Abstract: Le couvercle chauffant électrique de la présente invention est un dispositif de cuisson et chauffage d'aliments nécessitant un couvercle, qui assure une cuisson en surface par transfert intensif et uniforme de chaleur au-dessus des aliments en cours de cuisson dans une cocotte, une poêle ou une poêle à frire. De nombreux aliments nécessitent un chauffage en surface permettant d'empêcher le débordement des aliments. Ces aliments sont mieux cuits et plus rapidement s'ils peuvent être chauffés simultanément des deux côtés, et la présente invention concerne la cuisson de tels aliments. L'appareil de cette invention est un couvercle qui s'adapte à diverses tailles de cocottes, poêles ou poêles à frire pour permettre de griller, cuire, chauffer la surface de produits alimentaires, ou pour faciliter le processus de cuisson à la vapeur du riz. Cet appareil comprend un couvercle incurvé métallique (24), un élément barrière résistant à la chaleur (64), des éléments chauffants à résistance électrique (52), un panneau de garniture inférieur fortement thermoconducteur (40), un évent à vapeur (41) ménagé dans un bouton (21) qui comprend un élément rotatif permettant l'échappement de la vapeur, une poignée creuse (35), longue et amovible, qui contient les dispositifs électriques et transmet l'énergie de la source électrique aux éléments chauffants présents dans le couvercle ainsi qu'une poignée transversale fixée au couvercle et permettant de soulever facilement ce dernier. En outre, afin de garantir la sécurité, un plateau doté de quatre pieds et résistant à la chaleur est associé au couvercle chauffant électrique pour que ce dernier y soit placé lorsqu'il n'est pas utilisé.

Title: Trench gate metal oxide semiconductor transistor
Inventor: SOLOMON ALLEN L
IPC: H01L29/423
Filed: 1990-01-17
Abstract: Abstract of the Disclosure A process  for  forming  a  trench  gate  metal-oxide semiconductor transistor, and the resulting structure  are disclosed.  The transistor is formed  by forming a  trench in the semiconductor substrate which is used to  construct the gate region.   Regions adjacent  the upper surface  of the trench are doped to form source and drain regions. A layer of insulator  is applied  along the  surface of  the trench and  a  conductive  layer,  forming  the  gate,  is applied on the surface of the trench above the  insulating layer.    The  source  and  drain  regions  are  therefore separated by the trench and the  gate region is separated from the source and drain regions by the insulating  layer lining the trench surface.

Abstract: A device for deterring theft of a protected article, including a pin and clutch for attaching the device to the article, with the pin and clutch being embodied in two components that are adapted to be locked together on opposite sides of a portion of the protected article to prevent unauthorized removal of the device from the article. One component includes a plurality of fragile elongated vials that fracture when flexed longitudinally, with each vial containing a detrimental substance that would damage the article if the vial were to be fractured while the device was attached to the article. The vial-containing component is so structured as to include a plurality of regions in which the vial-containing component flexes more easily in a predetermined direction than in other directions and regions, with the predetermined direction of easier flexing being different in different said given regions; and the vials era respectively disposed within each of the given regions of the vial-containing component such that when any of the given regions of the vial-containing component is flexed in the predetermined direction of easier-flexing for said given region, the vial disposed in said region is flexed longitudinally and fractures to thereby release the substance contained therein. The other component is so structured as not to flex when an attempt is made to pry the vial-containing component from the other component while the two components are locked together, thereby concentrating flexure forces resulting from said prying in the vial-containing component.
