Title: Method for directly depositing metal containing patterned films
Inventor: HILL ROSS HENRY
IPC: H01L21/3205
Filed: 1995-11-10
Abstract: A photoresist-free method for making patterned films of metal oxides, metals, or other metal containing compounds is described. The method involves applying an amorphous film of a metal complex to a substrate.  The film may be conveniently applied by spin coating using standard industry techniques. The metal complex used is photoreactive and undergoes a low temperature chemical reaction in the presence of light of a suitable wavelength. The end product of the reactions depends upon the atmosphere in which the reactions take place. Metal oxide films may be made in air. Patterned films may be made by exposing only selected portions of the film to light. Patterns of two or more materials may be laid down from the same film by exposing different parts of the film to light in different atmospheres. The resulting patterned film is generally planar. Separate planarization steps are not generally required.

Abstract: In sorter systems of the grader type a selective unloading or throwing out of conveyed objects is effected, from a conveyor (8) to selected receiver stations therealong. Each of these stations is equipped with a receiver bin (10) having a bottom outlet valve (22) and an upper mouthing, which, due to some spreading in the unloading function, should have a certain minimum size. In order to increase the capacity of such a system without prolonging the conveyor, the invention provides for the receiver stations to comprise more than one operative receiver bin or bin section each, which are currently switchable in a controlled manner. Preferably, use is made of a single, fixed container (10) separated in two sections with individual bottom valves, viz. separated by means of a pivot plate (18), which, with a maintained full size of the container mouthing, is pivotable against two opposed container walls for selectively guiding the received articles to the respective two sections, from which the collected article portions may be let out individually.

Patent CA-2228480-A1 (CA)
Inventor: COPE DENNIS
IPC: B65D81/07
Filed: 1996-06-05
Abstract: La présente invention se rapporte à un récipient sans valve pour fluide ou pour gaz et qui se ferme hermétiquement de lui-même, pouvant être utilisé dans une grande diversité d'applications, notamment des matériaux de calage, de remplissage, des matelas, des radeaux et autres. Le récipient est formé d'un ou plusieurs éléments gonflables (101) se fermant hermétiquement d'eux-mêmes, chaque élément gonflable étant formé d'une paire de cellules gonflables (103, 105). Chaque cellule est composée d'une feuille intérieure (17) et d'une feuille extérieure (109) de matériau thermoplastique ou imperméable, les feuilles étant scellées ensemble à leurs bordures (111), définissant ainsi la cellule gonflable. Les feuilles intérieures (107) de chaque cellule dans la paire sont scellées ensemble de telle sorte que les bordures du joint hermétique définissent un conduit (115) de remplissage à travers lequel le fluide ou le gaz peut passer entre les cellules. Des passages (119) dans les feuilles intérieures des deux cellules à l'intérieur du conduit de remplissage permettent au fluide ou au gaz de passer du conduit de remplissage vers les deux cellules afin de provoquer le gonflage. Lorsque les cellules ont été entièrement gonflées, la pression interne du gaz et les forces d'étirement latéral conduisent les feuilles internes de cellules de venir en contact, ce qui provoque la fermeture du conduit de remplissage, et isolant ainsi les passages de l'environement extérieur et provoquant la fermeture hermétique automatique du récipient. En outre, le récipient peut être créé en utilisant des agencements de tels éléments de fermeture hermétique automatique pouvant être gonflés individuellement ou à partir d'une source unique alimentant un distributeur commun.
