Patent EP-0406764-A2 (EP)
Inventor: ERNSTBERGER JOHANN
IPC: G01R1/073
Filed: 1990-07-02
Abstract: The invention relates to an adapter for testing integrated circuits (8) mounted on a film, with the aid of a test device containing a load board (2) with spring-loaded needle contacts (10). The test device itself contains a load board of complex construction on which spring-loaded contact needles are located in a pattern which is advantageous for the production of this board. Since the grid dimensions of the chip connections (1) (spider) are much smaller than the grid dimensions of the spring-loaded contact needles (10) of the load board (2), it is not possible to test such chips mounted on film without changing the grid dimension of the load board (2). To eliminate this disadvantage, the invention provides that an intermediate circuit board (4) with conductor tracks fanning out from the centre is arranged to adapt the chips with the load board (2) of the test device, the grid pattern in the centre corresponding to the grid pattern of the chip terminals (1) and the grid pattern at the periphery corresponding to the grid pattern of the load board and the chip terminals (2) being pressed against fixed needle contact pins located at the circuit boards of the centre by means of test stamps (7). <IMAGE>

Abstract: In a method of forming an insulating film, a first insulating film of silicon dioxide is formed on a silicon substrate by performing heat treatment in an oxidizing gas atmosphere which does not contain nitrogen, and then a second insulating film of oxynitrided silicon dioxide is formed on the first insulating film by performing heat treatment in an atmosphere which contains nitrogen. The steps of forming a silicon dioxide film and an oxynitrided silicon dioxide film may be repeated to obtain the insulating film of the desired thickness. Prior to the formation of the silicon dioxide and oxynitrided silicon dioxide films, the silicon substrate is cleaned by heating it in a reducing gas atmosphere, and then heating it in a reactive gas atmosphere.

Abstract: An ultrasonic inspection and imaging instrument for scanning an object (16) under examination, the object having an inspection plane at a predetermined depth, in the direction slanted to the depth (slant scanning), in such a way as to cause rectilinear scanning as viewed from the plane. Measured data on a peak value corresponding to each measurement point obtained from the slant scanning is displayed in the form of a picture on the screen of a display (12) relative to each measurement point. The image displayed at that time is most clearly demonstrated, provided an image portion in the vicinity of a test portion corresponding to a test surface is brought into focus in the depth direction. An operator is supposed to select the image portion clearly indicated out of the picture displayed on the display (12) and to input the position of the image thereon to an input unit, whereby an image processor (10) bases the positional information about the display data thus fed and the relevant information indicating the positional relationship in the depth direction on obtaining the position of the probe (3) in the depth direction when the measured value resulting from the image is collected. The image processor (10) positions the probe thereat, so that the probe (3) is automatically focused on the test surface.

Abstract: The present invention uses tunable and fixed frequency lasers as an optical light source in imaging laser detection and ranging (LIDAR) systems. This invention provides a high energy, short pulse length laser output which is tunable to or set at a desired wavelength. The tuning is used for performance optimization of lidar system; and for scientific investigations carried out using these systems. An example of performance optimization is the tuning to or setting of the laser at the so-called Jerlov minimum, which is dependent upon the optical characteristics of the particular water used. The improved system may be used for scientific investigation, such as determining K s  (the frequency-dependent optical attenuation coefficient) in the ocean at depth, as well as imaging various opaque objects under battlefield conditions, at depth. This invention has the effect of significantly improving the optical signal to noise ratio for all of these applications.

Abstract: A flat panel display is provided with overlying interconnected and hence redundant bus lines (90, 94; 82, 86) to reduce fatal defects. The redundant, generally row lines (90, 94) are interconnected at least at two locations (92, 96) on a line and can be connected at each pixel (72) to further reduce defects. The redundant row or gate line is formed by an overlying light shield line (132) which preferably is of low resistivity and enhances the operation of the displays. The pixels (72) can be subdivided into subpixels (74, 76, 78, 80) and one defective subpixel is generally an acceptable non-fatal display defect, since the rest of the subpixels are still operative. The subpixels can be formed with common or redundant column bus lines (82, 86)

Abstract: A package having means for producing an audible signal, such as a "click", which signals the consumer as soon as a predetermined level of engagement between a container and a closure has been achieved. Normally the desired level of engagement establishes some type of seal between the package components which contact one another. In a particularly preferred embodiment, a semi-rigid polymeric container having a discharge orifice, a sealing member preferably comprising a filter support member secured across the discharge orifice of the container and a closure having attachment means capable of forming a substantially gas-tight atmospheric seal between all three components upon initial closing of the package to the atmosphere is provided. The container and closure are further provided with interfering projections, at least one of which is resiliently deformable, which will contact one another only after the sealing member has been removed from the package and discarded and the closure reapplied to the container. These projections are so positioned relative to the sealing surfaces on the closure and container that the projections cannot interfere with one another until after the closure and container have achieved the desired level of engagement with one another. In a particularly preferred embodiment, means to prevent overtorquing of the closure onto the container after the audible signal has been sounded are also provided.

Abstract: Because of the heavy thermal stress, high-load electric lamps have a quartz-glass lamp bulb. During operation, these lamps produce high-energy UV radiation which is transmitted almost unattenuated by the quartz-glass vessel and which is in many cases undesirable and even harmful. The novel lamps therefore have on their lamp bulb (1) a UV-absorbing coating (6) containing CeF3 and Al2O3.SiO2 in a ratio by weight of 2:1. To produce the coating, a suspension of CeF3 and Al2O3.SiO2 in industrial alcohol is prepared and finely ground. After further dilution with industrial alcohol and possibly adding nitrocellulose as a binder, the suspension is applied to the lamp bulb (1), dried and then fired. <IMAGE>
