Title: Method and device for copy grinding inner surface of weld groove
Inventor: TSUJI JIROU
IPC: B24B17/00
Filed: 1979-12-29
Abstract: PURPOSE: To grind the entire inner surface of a weld groove uniformly by making a grinding wheel copy a weld groove under a constant grinding pressure to grind the inner surface, and when it becomes impossible to move forward, by swivelling the grinding wheel to make it copy towards the bottom of the weld groove.  
     CONSTITUTION: While a grinding wheel 27 is pressed against the inner surface of a weld groove 36 by spring 30 to copy the surface, a copy control mechanism P is moved forward to the direction of the depth of the weld groove 36. When the grinding wheel 27 grinds to the bottom 36" of the groove, the forward movement of the copy control mechanism P becomes impossible and the drive of a straight feed driver 7 is stopped, while the hydraulic motor of a swivelling feed driver 14 is rotated forwardly to swivel the copy control mechanism P horizontally and make the grinding wheel 27 copy to the bottom direction of the weld groove 36. Next, when the swivelling of this mechanism P becomes impossible, this mechanism P is swivelled reversely to return the grinding wheel 27 to its position before the swivelling. By moving back this mechanism P in the direction of depth for a distance corresponding to the depth of the weld groove 36, the grinding wheel 27 is returned to its initial position.

Title: Catalyst for converting c3 and c4 hydrocarbon and conversiontherefor
Inventor: KOLTS JOHN HENRY
IPC: C07B61/00
Filed: 1986-07-23
Abstract: Novel compositions of matter include: mixed oxides of (a) at least one oxide of chromium, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals, preferably lanthanum and cerium, and/or niobium; (b) at least one oxide of chromium, at least one oxide of calcium, strontium, tin and/or antimony, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals and/or niobium; - (c) at least one oxide of chromium, at least one oxide of iron and at least one oxide of magnesium, , Lanthanum Series metals and/or niobium; and (d) at least one oxide of chromium, at least one oxide of liron, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals and/or niobium. These compositions are particularly effective as catalyst compositions for the conversion of C, and C, hydrocarbons to less saturated hydrocarbons, with high selectivities to ethylene and ethane and particularly ethylene, and the addition of the chromium significantly extends the activity of the catalyst for such selective conversion before regeneration is necessary. A method of converting C, and C, hydrocarbons to less saturated hydrocarbons, and selectively to ethylene and ethane and particularly ethylene, is also disclosed. Carrying out the process in the presence of steam is essential to the process when the catalyst contains iron and is optional when the catalyst does not contain iron. Limiting the amount of bound or fixed sulfur in the catalyst also improves the catalyst.

IPC: G01B11/24
Filed: 1991-07-15
Abstract: PURPOSE:To obtain a general purpose optical device which can measure an unspecific object shape with high accuracy by recording the reference wave front in a liquid crystal element. CONSTITUTION:Interference fringes having a feature of a reference object shape is formed on the image pickup screen of a camera 108 by a laser light source 100 and a Michelson type interferometer. An output of the camera 108 is A/D- converted, and inputted to a computer 109. During this time, only a bias voltage is applied to a liquid crystal element 104, so that the reference wave front becomes a plane. The liquid crystal element 104 is used as a phase shifter, and the shape of a reference object is calculated by a fringe scanning method. Calculated shape data is inputted to the liquid crystal element 104 through a signal generator 110, and a phase distribution corresponding to the shape of the reference object is made. This phase distribution becomes the reference wave front of the interferometer. In such a state, when an object to be measured is placed in a position of the reference object, interference fringe are formed between the reference wave surface reproduced from the liquid crystal element 104, and the object wave surface. The interference fringes are inputted to the camera 108, and displayed on a monitor 111.

Abstract: PURPOSE:To realize a diffusion-preventing layer whose wiring resistance is small and whose close contact property with an upper layer and a lower layer is good by a method wherein a first diffusion-preventing layer is formed on the surface of an interlayer insulating film in parts other than a contact part and a second diffusion-preventing layer is formed on its surface and on the inside of a contact hole. CONSTITUTION:An interlayer insulating film 7 composed of SiO2 is formed; after that, a first diffusion-preventing layer 13 whose material is TiW is formed on it in a film thickness of about 200Angstrom  by a sputtering method. The layer 13 and the insulating film 7 are etched; contact holes 10 are made. A remaining resist 12 is removed; after that, a second diffusion-preventing layer 14 whose material is W is formed in a film thickness of about 1800Angstrom  by a sputtering method. Then, an aluminum-based alloy layer 9 is formed by a sputtering method. The W of the layer 14 has a property that its close contact property is good with reference to two layers of the layer 13 and the layer 9. As a result, the layers are not stripped off. The layer 14 of the W whose electrical resistance value is small comes into direct contact with a source region 2 and a drain region 3 and the resistance at the contact parts is reduced.

Title: Floating point arithmetic processor
Inventor: KATSUNO AKIRA
IPC: G06F7/552
Filed: 1988-07-15
Abstract: PURPOSE:To increase arithmetic processing speed for extraction of the square root by supplying the output of a bit inverting circuit to a rounding circuit via a multiplexer only in a partial arithmetic process for extraction of the square root and performing a right shift by one bit after addition of 1 to the minimum digit. CONSTITUTION:A multiplexer 8 supplies the output of a bit inverting circuit 7 to a rounding circuit 6 only in a partial arithmetic process for extraction of the square root. The output of the circuit 7 receives 1 at its minimum digit and is shifted to the right by one bit in the circuit 6. Otherwise the output of a right shift circuit 5 is supplied directly to the circuit 6 via the multiplexer 8. Thus it is possible to perform the binary calculation of 1/2*(3-AXi) where 0<AXi<=1 is satisfied in a single step via an arithmetic processor capable of the multiplication of floating points just with addition of the circuit 7 and the multiplexer 8. Then the repetitive calculation is carried out at high speed for the extraction of the square root.
