Title: Manufacture of tillage tooth
Inventor: NAGAMINE YOSHIFUMI
IPC: A01B33/10
Filed: 1986-01-10
Abstract: PURPOSE:To make the titled tooth light in weight, and also to prevent soil from being held in, by forming an oblong hole in the center part of an edge part of a tooth base material, and closing up the oblong hole by making its peripheral wall flow. CONSTITUTION:As for a tooth base material 10', an edge part 11' has a uniform thickness T extending over the whole surface, and in a part corresponding to a thin wall part 14 of this edge part 11', many oblong holes A are pierced in parallel at an interval by a punch press B. The oblong hole A is formed so as to be long roughly in the tooth rotating direction, and to be vertical to the center line. The tooth base material 10' which has been pierced is set to a press machine, and pressed by a pressure die P of a shape corresponding to a recessed part 15. By this pressure, a material of the periphery of the long hole A flows in all directions, concentrated so as to close up, and in the end, the oblong hole A is closed up and only a linear buried mark (a) is left. Accordingly, as for the material between the oblong holes A, that of a wall thickness T before stamping is varied to a wall thickness (t), the thin wall part 14 and the recessed part 15 are formed therein, and absorbed due to a fact that the oblong hole A is crushed.

Title: Method for pickling steel sheet
Inventor: SAIDA FUMIHIRO
IPC: C23G1/08
Filed: 1993-01-13
Abstract: PURPOSE:To remove an oxidized film on a steel sheet surface and to prevent discoloration by recognizing a pickling removing performance under relations between a pickling liquid concentration and a pickling liquid temp. and recognizing the presence or absence of subsequent discoloration under relations between a pickling liquid concentration and a line speed. CONSTITUTION:In a continuous annealing line, the generation of three kinds of typical oxidized films is expected. An oxidized film of type A is an extremely thin oxidized film generated in ordinary operation conditions. An oxidized film of type B is a thick oxidized film generated when an oxygen concentration or a dew-point in a furnace is high. An oxidized film of type C is one in which the oxidized films of type A and type B are laminated. Before real operations, an oxidized film removing performance under relations between the pickling liquid concentration and the pickling liquid temp. and the presence or absence of subsequent discoloration under relations between the pickling liquid concentration and the line speed are previously investigated for each oxidized film state generated on the steel sheets. Corresponding to the circumstances, pickling is performed by successively changing the conditions at the lower region capable of removing oxidized films.

Title: Semiconductor device
Inventor: MINOWA MASAYUKI
IPC: H01L23/522
Filed: 1989-01-10
Abstract: PURPOSE:To improve the yield rate of a multi-layer wiring structure semiconductor device and the reliability by providing a dummy wiring in parallel to a lower-layer wiring at a place where wiring layers cross. CONSTITUTION:When stress is applied thermally, an upper-layer wiring 5 shifts about 2-3mum by the difference of thermal expansion coefficient between silicon 1 and mold resin 7. For this reason, there is a case where cracks occur in an interlayer insulating film 4, and the dummy wiring 3' at the lower-layer and the upper-layer wiring 5 short-circuit. Also, the lower-layer wiring 3 and the lower-layer dummy wiring 3' are put at a proper distance, for example, at the minimum winding space which can be allowed in view of accuracy in processing, and when a flattening technique is adopted for formation of the interlayer insulating film 4, the upper-layer wiring 5 is flattened above the lower-layer wiring 3 and the lower-layer dummy wiring 3', and the stress of mold resin does not affect the lower-layer wiring 3. Hereby, even if cracks occur in the interlayer insulating film and the upper-layer wiring and the dummy wiring short-circuit, the short circuit between the upper-layer wiring and the lower-layer wiring can be avoided, and it can operate without problem in properties.

Abstract: PURPOSE:To reduce update processing time and to make it possible to always use a latest distributed file by users by replacing the record of a distributed file by a new one when a record which is newer than the record of the distributed file exists in the record of a master file. CONSTITUTION:When a distributed file 2 is used, the file history BFR of the distributed file 2 is compared with the file history MFR of a master file 1 at first. In the case of BFR=MFR, the distributed file 2 is used as it is and a message processing is started. But, in the case of BFRnot equal to MFR, the file history BFR of the distributed file 2 is compared with the record history MRRi of the master file 1. As a result of this comparison, if the record to be FR MRRi exists, a pertinent record 1i of the master file 1 is copied to the distributed file 2. Then, the message processing to be an original processing is started.

Abstract: PURPOSE:To prevent the influence of the light going backward, by giving the constitution where respective lights emitted from plural pairs of light sources pass the interference film filter and the anisotropic crystal once through the optical system and are coupled to one light waveguide path. CONSTITUTION:The horizontal polarized light emitted from light source 11 is connected to subordinate light waveguide path 2 directly or through the optical system such as a lens and is led to collimator lens 41. The light converted to a parallel light by collimator lens 41 passes through interference film filter 6 and is condensed by focusing lens 5 and is led to anisotropic crystal 7, and this horizontal polarized light is led to light waveguide path 3. Meanwhile, though the vertical polarized light of the different wavelength from light source 12 is incident to anisotropic crystal 7 through the same light path as the light from light source 11, the light path is bent, and this light coincides with the light from light source 11 at the emission end of anisotropic crystal 7 and is led to light waveguide equipment 3. Similarly, light emitted from light sources 13 and 14 are reflected by interference film filter 6 and pass through the same light path as lights from light sources 11 and 12 and are led to light waveguide path 3.
