As a result, differences in level, of the insulating film 8, which are produced among individual interconnection layers 7a, 7b, 7c can be reduced, and the surface can be flattened. As a result, the coverage of interconnection layers 12a, 12b as next layers can be made good, and the layers are hard to disconnect. At this time, the metal ring 13 is formed when the interconnection layer 12a, 12b are formed.

     CONSTITUTION: A rotating side work piece 2 is gripped by a rotary chuck 1, and a stationary side work piece 3 is placed in the set position. The stationary side work piece is gripped with clamps 4, 5 and pressure cylinders 12 are actuated to move the clamp bases 7, 7 in the direction of pressure-sandwiching the same, whereby gripping claws 13, 13 are contacted with the work piece. At this time, the gripping  claws are oscillatable about the pins 14, 14 and therefore even if the center of the  gripping part of the work piece 3 deviates from that of the body part, it may be  gripped in the form conforming to the same. When the gripping of the work piece 3  is finished, friction-pressure-welding is done by a conventional method. Since the  work piece is firmly gripped near the faying part, the occurrence of vibrations is  obviated.

Title: Method and apparatus for binary data processing
Inventor: ERUNSUTO AUGUSUTO MUNTAA
IPC: H04L7/04
Filed: 1987-03-25
Abstract: The invention provides a method of redundantly encoding 2<n> binary words into 2<m> encoded binary words, wherein m > n, well as circuits for the encoding and decoding of the encoded binary words. The m words exhibit x invariant bits between themselves and the n words and the m - x bits are mapped uniquely to the remaining n - x bits of the binary words. As a result, the encoding and decoding circuits require translation devices of greatly reduced size from what would be expected through conventional design. The encoded data also exhibits all the desirable attributes of edge density and DC balance.

Filed: 1989-03-23
Abstract: PURPOSE:To enhance triboelectrifiability and coloring ability by mixing the water-containing cake or the aqueous dispersion of an organic pigment with a monomer, migrating and dispersing the pigment into the monomer phase from the aqueous phase by flashing treatment, and then polymerizing the monomer to form the polymer particles each containing the finely dispersed pigment. CONSTITUTION:The color developer of a polymer containing the organic pigment is prepared by mixing the water-containing cake or the aqueous dispersion of the organic pigment with the monomer, migrating and dispersing the pigment into the monomer phase, and then polymerizing the monomer to form the polymer particles each containing the finely dispersed pigment. The pigment cake or aqueous dispersion dispersed into an aqueous medium in a finely dispersed state is, in the usual case, dried and dispersed into the polymerizable monomer by kneading or the like. On the contrary, in this method, the pigment dispersion is migrated and dispersed into the monomer phase without agglomerating the fine particles of the pigment, thus permitting coloring ability and triboelectrifiability to be enhanced.

Filed: 1987-03-23
Abstract: PURPOSE:To constitute a high speed type photoelectronic integrated circuit, by integrating a hetero-bipolar transistor, which can respond at a high speed, and a PIN photodiode having a light guide layer. CONSTITUTION:A PIN photodiode in a photodetector part is reverse-biased. A depletion layer is expanded in a light absorbing layer 4. Signal light 13, which is inputted into a light guide layer 5 that is held between an emitter layer 2 and a region as a clad layer, i.e., an N-InP layer 7, is propagated toward the light absorbing layer 4 in the light guide layer 5 and absorbed in a depletion layer. Thus electrons and holes are generated. The electrons and the holes become a current in the reverse direction with respect to the PIN junction by an electric field. Said current is supplied from a region of a photodetector part in a base.anode layer 3 into a region in the same base.anode layer 3, which is to become the base of a hetero-bipolar transistor. The current is take out of an emitter electrode 9 and a collector electrode 11 as an amplified signal current. Therefore, a base resistance value becomes low and the junction capacitances between the emitter and the base and between the collector and the base become small. Thus the high speed operation can be carried out.
