Patent EP-0304145-A2 (EP)
Inventor: GUHA SUBHENDU
IPC: H01F1/04
Filed: 1988-05-12
Abstract: One or more thin film solar cells (10) in which the intrinsic layer (18) of substantially amorphous semiconductor alloy material thereof includes at least a first bandgap portion and a narrower bandgap portion. The bandgap of the intrinsic layer is spatially graded through a portion of the bulk thickness, said graded portion including a region removed from the intrinsic layer-dopant layer (16, 20) interfaces. The bandgap of the intrinsic layer is always less than the bandgap of the doped layers. The gradation of the intrinsic layer is effected such that the open circuit voltage and/or the fill factor of the one or plural solar cell structure is enhanced.

Abstract: The invention relates to insulating lightweight refractory materials which are resistant to attack by molten metals, particularly molten aluminum and its alloys and compositions used to form such materials. More particularly, the invention provides a settable composition which comprises a mixture of ceramic fibres, wollastonite powder and aqueous colloidal silica having a solids content of about 5-25% and preferably 12-15% by weight. The weight ratio of the ceramic fibers to the wollastonite powder is 0.8-1.2 : 1.5-2.5, respectively. The composition option­ally contains carbon fibres or metal fibres as reinforce­ments. The composition can be cast to form shaped products or used as a joining material or as a "face-off" material to protect an underlying article. When dried, the composi­tion forms a material which is insulating, lightweight and resistant to high temperatures and chemical attack by metals. The material can be made even more resistant to attack by a silicate and/or fluoride surface treatment. The material is useful for forming items used in metal foundries and the like.

Abstract: According to the present invention, a cursor (41) is displayed on a screen of display of a supersonic image obtained by scanning the surface of an inspection object by use of a probe formed by arrangement of array elements and, further, the cursor (41) is moved to a desired position of the supersonic image in a first display portion (40) so that supersonic waves are emitted to a position of the surface of the object (3) corresponding to the aforementioned position and the reflection wave signals are displayed in another display portion (42). Accordingly, not only supersonic flaw detection (C-scope) in a plane of the object can be conducted, but also supersonic flaw detection (B-scope) in the direction of depth in a desired position of the object can be conducted simultaneously. Consequently, detailed flaw information, such as a flaw type, a flaw position, a flaw size and a flaw shape in the object can be detected quickly.

Abstract: An apparatus for and a method of addressing data storage elements (16) employs an ionizable gas to address the storage elements for storing data in and reading data out of them. The storage elements are defined by the overlapping areas of multiple column electrodes (18) extending in a common direction on a first substrate (48) and multiple channels (20) extending in a common direction on a second substrate (54). A layer of dielectric material (46) separates the first and the second substrates, which are positioned face-to-face and spaced-apart with the direction of the channels transverse to that of the column electrodes. Each of the channels is filled with an ionizable gas and includes a reference potential electrode and a row electrode electrically isolated from each other. The column electrodes receive data drive signals, and the row electrodes and reference potential electrodes receive data strobe signals. The addressing apparatus is configured so that for each storage element the ionizable gas functions as an electrical switch that changes between a conducting or plasma state and a nonconducting or de-ionized state in response to an applied data strobe signal. The ionizable gas functions to either store data in or read data out of the storage element. If the storage element includes a layer (44) of material having electro-optic properties and receives incident image-carrying light, the ionizable gas functions to select and store image data across the layer and thereby provide a display system having gray scale luminance.

Abstract: The pliable portion of the article (80) has a first end portion (1) and a second end portion located at opposite ends of the encircling portion of the article. The first end portion (1) includes an elasticized fastening system (120) having at least one segment (15) which is capable of being elastically shirred along at least a portion of its length. The shirrable portion of the segment (15) comprises an elastomeric member which, prior to the securement of the first and second end portions of the article to one another, is maintained in a prestretched and tensioned condition in the desired direction of shirring. The opposed ends of the shirrable segment in the article (80) are interconnected to one another through the prestretched and tensioned elastomeric member. The prestretched and tensioned elastomeric member is maintained in tension by securing it in fixed relation to at least one rigidifying member (28) to form a composite structure which is strong enough to resist collapse in a direction parallel to the tensile forces acting upon the prestretched and tensioned elastomeric member. In a particularly preferred embodiment, the rigidifying member (28) has a fixed portion (30) permanently secured to the first end portion (1) of the article (80) and a releasable portion (32) which can be separated from the first end portion of the article. The releasable portion (32) of the rigidifying member (28) preferably includes means for securing it to the second end portion (2) of the article (80), and the act of affixing the releasable portion (32) of the rigidifying member (28) to the second end portion (2) of the article (80) automatically releases the tension in the prestretched elastomeric member.   Elasticized fastening systems of the present invention can be produced at high speed from continuous webs and cut into discrete segments which are transferred onto a continuously moving web at predetermined points along its length, all while the elastomeric member is maintained in its prestretched and tensioned condition by the rigidifying member.

Abstract: In a method for Liquid Phase Epitaxy (LPE) of semi-­insulating InP, a solution of P, Ti and a p-type dopant in molten In is cooled in a non-oxidizing ambient at a surface of a substrate to grow an epitaxial layer of doped InP on the surface. The concentration of p-type dopant in the solution is such as to provide a concentration of p-type dopant in the grown epitaxial layer greater than the aggregate concentration of any residual contaminants in the grown epitaxial layer, and the concentration of Ti in the solution is such as to provide a concentration of Ti in the grown epitaxial layer greater than the concentration of p-type dopant in the grown epitaxial layer. The required melt concentrations are determined empirically. The method can be performed at temperatures below 650 degrees Celsius and is particularly suited to the LPE growth of semi-insulating InP to isolate InP-InGaAsP buried heterostructure lasers.
