Title: Forming method of multilayer interconnection structure
Inventor: HORI MINORU
IPC: H01L21/3205
Filed: 1983-04-12
Abstract: PURPOSE:To prevent wire breakdown and defective insulation, by forming a groove in a silicon oxide film, forming a first metal layer only in the groove, forming an interlayer insulating layer and a second metal layer sequentially, thereby reducing the difference in steps formed at the end parts of the wiring metal layers. CONSTITUTION:A photoresist film 6 is attached to a silicon oxide film 6, which is formed on a silicon substrate 1. A groove is formed in the silicon oxide film 2 by etching the part of an opening 7. A metal for the first wiring layer of Al and the like is deposited, heat treatment is performed, and a first metal layer 3 is formed in the groove. Thereafter, the photoresist film 6 is removed, and an unnecessary metal layer 3' is removed together with the photoresist film 6. Then, an interlayer insulating layer 4 is formed, and finally a second metal layer of Al and the like are formed. Since the first metal layer 3 is embedded in the silicon oxide layer 2, the difference in steps yielded in the interlayer insulating layer 4 and the second metal layer 5 at the end parts can be reduced.

Title: Addition system and its circuit
Inventor: SUZUKI KAZUMASA
IPC: G06F7/50
Filed: 1991-03-28
Abstract: PURPOSE:To increase the adding speed of two numbers by processing previously the carry signals which are continuously propagated in order to eliminate the carry propagation and also to simplify the hardware configuration by applying frequently a simple logical arithmetic for each bit. CONSTITUTION:When two numbers A and B are added together, the carry processing is previously applied to a part where the carry signals are continuously propagated. Then the value given in such a form that causes no carry propagation is deformed so as to increases the adding speed of the two numbers. An AND X and an OR Y of numbers A and B are obtained by an AND circuit 1 and an OR circuit 2. A carry range detecting circuit 3 obtains the value M showing a carry occurrence range from the values of X and Y. Then an EX-OR circuit 4 applies the batch carry processing to Y, and an EX-OR circuit 5 performs the addition for each bit to obtain a sum S.

Title: Method for measuring laitance thickness on upper surface of concrete
Inventor: NISHIDA HIROKAZU
IPC: G01N11/00
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To measure the thickness of a laitance layer by removing a spherical body having the radius larger than the thickness of the laitance layer after pressing the spherical body into the laitance layer to measure the diameter of the spherical trace on the surface of the laitance layer and figure out the thickness of the laitance layer from the diameter of the spherical trace and the diameter of the spherical body. SOLUTION: A steel ball V having the radius r larger than the thickness of a laitance layer U is placed on the laitance layer U and pressed from above into the laitance layer U. Thereafter the steel ball V is removed to measure the diameter d of the spherical trace on the surface of the laitance layer. Assuming that the center of the steel ball V is O and the diameter d of the spherical trace is PQ, r=OR=OP=OQ is obtained, so that assuming that the thickness of the laitance layer U is (x), OP<2> =PS<2> +OS<2> , i.e., r<2> =+OS<2> is obtained. Thus, since OS<2> =r<2> -(d/2)<2> and thereby RS=OR-OS, x=r-(r<2> -(d/2)<2> )<1/2> is obtained. By this method, the thickness (x) of the laitance layer U can be simply quickly measured.

Title: Low-temperature decomposition method of hardly decomposable polyhalogenated organic compound
Inventor: MATSUNAGA KAZUYOSHI
IPC: A62D3/176
Filed: 1994-04-01
Abstract: PURPOSE:To provide an efficient and simplified photochemical low-temp. decomposition method of hardly decomposable polyhalogenated org. compds. CONSTITUTION:A soln. mixture composed of a methanol soln. of the hardly decomposable polyhalogenated org. compds, such as PCBs, semiconductors (SiC, TiO2, etc.) and an aq. ferric salt soln. is heated up to 75 to 95 deg.C by heat generation and the org. compds. are decomposed by the free radical mechanism when 60% H2O2 is slowly dropped while the soln. mixture described above is irradiated with low-pressure UV light. Electrons are excited by the low- pressure UV light in the semiconductors immersed in the soln. These excited electrons reduce Fe<3+> to Fe<2+> and hydroxy free radicals (.OH) are generated by reaction of the F<2+> and H2O2. These free radicals decompose the org. compds. The excited electrons act on dissolved oxygen to form superoxide (O2<->). The decomposition reaction of the org. compds. is conceivably progressed by action of this O2<-> on the Fe<3+>.

Abstract: PURPOSE:To tilt an edge part in the forward direction of a wiper blade without fail irrespective of the travel speed of a vehicle, by changing a tilt angle of the wiper blade to a glass surface separately in each case of outgoing and returning movements, and holding it rotatably to a wiper arm. CONSTITUTION:A wiper blade 4 is supported on a wiper arm 5 so as to cause its tilt angle to a windshield surface 2 differ in each case of outgoing and returning movements via a rotary supporting mechanism 20 so as to make the specified angle rotatable. Therefore, when the wiper blade 4 reciprocatively travels, there is produced frictional force between an edge part 7 of blade rubber 3 and the glass surface, whereby the rotary supporting mechanism 20 is turned round up to one side of rotation end points, and the wiper blade 4 is tilted to the forward direction side, thus the edge part 7 is tilted in the forward direction of the wiper blade 4. Therefore, an unwiped part and a chattering phenomenon due to air pressure to be produced at the time of car running are preventable.

Abstract: PURPOSE:To enhance heatproof characteristics by a method wherein at least one coil or more other than a main detecting coil for exciting a metal fiber is provided. CONSTITUTION:In an element in which a coil is wound on a magnetic core of a crystalline metal fiber 1 composed of an alloy of which a cross section is circular having a soft magnetic characteristic, and of which a main component is iron, this magnetic sensor has at least one coil 4 or more for exciting the metal fiber 1 in addition to a main detecting coil 3.
