Patent EP-0223527-A2 (EP)
Inventor: LEVY ROLAND ALBERT
IPC: H01L21/302

Abstract: A glass reflow step to round off sharp edges of contact vias (42,44) is typically included in processes for making integrated-circuit devices. In the course of making such devices with closely spaced vias, it has been found that unacceptable overhangs occur on the sidewalls of the vias. Neither changes in the composition of the glass nor modifications in the processing parameters of reflow were effective to avoid the overhang phenomenon. In accordance with the invention, it has been discovered that the overhang problem can be consistently avoided if the ratio of glass thickness (t) to via-to-via spacing (s) is about 0.4 or less.

Abstract: In an assembly device (2) for gluing together individual veneer sheets (1), a veneer web is formed, the veneer sheets (1) with a parallel fibre course thus being glued to one another in the transverse direction. The veneer web obtained is divided into suitable formats (24) by means of a clipper (5). These are transferred to a depositing device (6), on which a web (8) of laminating material is intermittently moved transversely relative to the oncoming format (24). When the web of laminating material is stationary at least in this region, a format is deposited. It is then fed in the fibre direction, that is to say in the longitudinal direction of the veneer sheet, by means of the web (8) of laminating material to a press (15), where gluing with the glue already contained in the web of laminating material takes place by the effect of heat. Advantageously, the format (24), before being introduced into the press (15), is fastened by means of an adhesive fastening device and likewise by the use of the glue or the like of the web of laminating material. The laminated formats are thereafter formed by means of an additional clipper (17) or else there is a winding of the web of laminating material equipped with formats in a longitudinal-format rolling-up device (19). <IMAGE>

Abstract: irst and second lines respectively receive first and second complementary input signals representing a binary bit. Each of the input signals has first and second logic levels respectively corresponding to a binary "1" and a binary "0". The input signals produce a current through a load in accordance with the relative logic levels of the first and second input signals. The difference between the logic levels of the input signals is amplified and introduced as a negative feedback to a particular one of the first and second lines in accordance with the relative logic levels of the signals on the lines. The feedback causes a current to be produced in the load with a polarity opposite to the polarity of the current produced in the load by the input signals and with a magnitude less than the magnitude of the current produced in the load by the input signals. The negative feedback is effective in minimizing the time for the load to respond to changes in the relative logic levels of the first and second input signals. In this way, the frequency of response to a system including the circuitry of this invention can be significantly increased. The embodiment described above may the used in a system in which first particular input signals are provided to identify a selected word and second particular input signals are provided to iden- itify a bit in the word one and in which a cell (a load) is selected common to the selected word and the selected bit. The circuitry described above may be included to minimize the time for producing in the load a signal representative of the selection of such cell.

Abstract: According to a oscillator circuit of the present invention, there is provided a negative switched capacitor circuit (10) having negative equivalent resistance, the value of which is determined according to the reference frequency and a frequency to be compared, and a positive switched capacitor circuit (20) having positive equivalent resistance, the value of which is determined according to the reference frequency. A constant DC voltage (V) is supplied in parallel to one terminal of the two switched capacitor circuits. The respective terminals of the switched capacitor circuits are commonly connected in order to produce the composite current of both output currents of the two switched capacitor circuits. The composite current is integrated by an integrator (30). Further, there is provided a Schmitt-type oscillating circuit (83). The oscillating frequency signal from the Schmitt-type oscillating circuit is supplied to the negative switched capacitor circuit. The higher level threshold voltage (V H ) of the Schmitt-type oscillating circuit (83) is determined according to the composite current of both output currents of the two switched capacitor circuits, thereby adjusting the frequency of the oscillating signal of the Schmitt-type oscillating circuit (83). The oscillating signal is supplied to the positive switched capacitor circuit. The lower level threshold voltage (V L ) of the Schmitt-type oscillating circuit is determined according to the composite current of both output currents of the two switched capacitor circuits. Therefore, the frequency of the oscillating signal of the Schmitt-type oscillating circuit is adjusted.

Abstract: To measure the amount of phenol or α-naphthol in an aqueous sample, the sample is (a) mixed in aqueous solution with a diamine (preferably an aniline e.g. having a para- amino group, e.g. p-diethylaminoaniline), in the presence of an oxidant (e.g. potassium ferricyanide, chloramine T, Na metaperiodate or H 2 0 2  and a peroxidase) to form a quinone dye having a maximum absorption near 670 nm, and (b) measuring the depth of color (absorbency) formed compared to that of a control. The concentration of phenol or naphthol can be calculated from the absorbancy of a standard solution. 
     The test sample can be one obtained from the action of an enzyme (e.g. an alkaline or acidic phosphatase, kallikrein or antithrombin III on a substrate (e.g. disodium phenyl phosphate) from which phenol or α-naphthol is liberated enzymatically; the enzyme activity can thus be determined. A reagent test paper can be dipped in a liquid sample (e.g. of urine) and developed with a drop of oxidant solution. 
     The method is rapid, sensitive and highly reproducible.

Abstract: The sensor apparatus (300) comprises a passive ring Sagnac interferometric arrangement having a light source circuit (308) and a series of three multi-turn fiber optic rings (302, 304, 306). The rings form three gyroscope channels, and an optics/modulator circuit (312) selectively switches optical waves emitted from the light source circuit (308) into the gyroscope channels. Nonreciprocal phase modulation is applied to the counter-propagating waves, and the waves are recombined so as to produce a "zero order" fringe pattern. The phase modulation produces an intensity signal which tends to alternate between values of substantially maximum change with respect to given changes in phase shift resulting from the non-reciprocal phase modulation. Optical waves are selectively applied to one particular gyroscope channel during a given time period, while the photodetector circuit (324) is detecting light waves from a ring path of another gyroscope channel. Signal processing circuitry (328) is time-shared with respect to signals associated with each of the   gyroscope channels. The optics/modulator circuit (312) can be realized by means of a single integrated optics chip.

Abstract: To reduce the mechanical stress of wool during washing, it is known, during a washing cycle, to provide longer intervals and changes of direction of rotation between successive drum movements of constant speed and, for a further reduction of the mechanical stress, to cause the drum to rotate at a constant speed of approximately 35 revolutions per minute intended specifically for this. The new method makes it possible to wash with a low degree of wool shrinkage and with low residual deformation, in which the movement times (1, 1') are always very short and are coordinated with the starting of the drum drive by means of a ramp (3), so that a drum speed of approximately 45 revolutions per minute is not exceeded. The method allows a careful washing of wool in drum-type washing machines. <IMAGE>
