Abstract: PURPOSE:To provide an optical pattern detection circuit which can detect a bit pattern as it is an optical signal and which does not deteriorate the quickness of light CONSTITUTION:The present circuit is devised utilizing the fact that 'when the bit pattern of (n) bits are added by properly variously weighting the respective bits, the added value has a unique value decided by the content of the bit pattern. This circuit is constituted so as to uitlize it.' By a weighting means 20 having optical circuit constitution, the respective bits of the inputted optical signal 250 are weighted. By an addition means 21 having the optical circuit constitution, the weighted respective bits (optical signals) 261-264 are added. By a comparison means 22 having the optical circuit constitution, it is compared and decided whether the power of the added optical signals (AL timing of 270) is the optical power peculiar to the bit pattern desired to be detected or not.

Title: Aluminum wiring method
Inventor: NUMATA ATSUSHI
IPC: H01L21/3205
Filed: 1987-07-03
Abstract: PURPOSE:To enable the selective aluminum wiring, by introducing conductive impurity like As in both ends of polycrystalline silicon resistor element to stop reaction with aluminum when the polycrystalline silicon resistor element or the like is formed in a wiring. CONSTITUTION:An n-type polycrystalline silicon resistor element 4 is formed in a part of wiring on which a polycrystalline silicon film 3 is spread after an oxide film 2 is spread. On both ends of the element, apertures are made. n-type conductive impurity As 6 is ion-implanted. After a resist 5 is eliminated, an oxide film 7 is spread, and heat-treated for activation. Aperture parts to bring aluminum into conact with the polycrystalline silicon 3 are made, and aluminum 8 is spread, which is subjected to patterning. When heat treatment is performed at a temperature lower than or equal to the melting point of aluminum, it reacts with polycrystalline silicon, but does not react with the polycrystalline silicon resistor element 4, because a region 9 in which As is ion-implanted acts as a stopper of reaction. A polycrystalline silicon resistor element can be formed in a part of a low resistive aluminum wiring.

Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To switch the order of articles easily by mounting a feeding belt capable of rotation of 180 degrees on a supporting part so as to reverse the arrangement at which articles are transferred from the feeding belt to a loading belt. SOLUTION: Articles on a feeding belt 1 is passed through from a belt 2 to belt 3, and a sensor 7 checks the respective destinations of articles. Grasping the destinations causes either of two cases; the placement of two articles is set as desired to load a machine without need for reversing the placement of loading, or the placement is not placed as desired and should be reversed. In the latter case, the articles are transferred from the belt 3 to a belt 8, and a supporting part 9 is rotated by 180 degrees to dispose the articles in reversed placement. Relative velocity between the articles and the belt receiving them is preferably zero so as to prevent the articles from rotating and the necessary alignment from being crashed down and so that the articles may pass through the one belt to the other belt. An intermediate transferring belt is applied for such a reason and transferring the articles from the belt 8 to the belt 11.
