Title: Treating method for anhydrous sodium dithionite production filtrate
Inventor: IIDA MITSUO
IPC: C01B17/66
Filed: 1978-10-05
Abstract: PURPOSE: To efficiently recover available salts contg. no sodium thiosulfate from a filtrate, obtd. by separating anhydrous sodium dithionite from a liquid reactant by filtration, by concentrating the filtrate to crystallize dissolved salts followed by hot filtration.  
     CONSTITUTION: Anhydrous sodium dithionite is produced using sodium formate as raw material. A liquid reactant contg. the dithionite is filtered to separate the dithionite, and the filtrate is concentrated to remove alcohol and water, thus crystallizing dissolved salts. The conc. filtrate is then hot filtered at about 48.2W60°C by centrifugal separation or other method. By this treatment most of salts available for production of anhydrous sodium dithionite can be separation-recovered as a mixt. contg. no sodium thiosulfate. The salts include sodium sulfite, sodium hydrogensulfite and sodium formate.

Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To provide a mechanism for linear movement with which a member to be moved can be moved smoothly and without being inclined while an installation space can be reduced. SOLUTION: A male thread part 31a and a cylindrical part 31b are formed on an outer peripheral surface of a screw shaft 31 and in pallel with a shaft center line, while a female thread part 4c threadedly engaged with the male thread part 31a and a fitting part 4d, which is fitted to an outside of the cylindrical part 31b, are formed in an inner peripheral surface of a cylindrical part 4B, which is provided so as to be connected to a holder 4A of a compensator lens group 4. A spring 32 installed between the cylindrical part 4B and a lens- barrel 2 energizes the screw shaft 31 toward a shaft supporting hole 2b of the lens-barrel 2. When the rotation of a motor 11 rotates the screw shaft 31 via a driving gear train 6, the cylindrical part 4B is guided/moved through sliding/contact between the fitting part 4d and the cylindrical part 31.  Thus, the compensator lens group 4 can be moved in the direction of an optical axis.

Title: Method for etching of fire-resistant metal layer at inside of parallel-plate reactor during manufacture of device on semiconductor substrate
Inventor: RITSUKII ERU DEIBISU
IPC: H01L21/302
Filed: 1992-04-17
Abstract: PURPOSE: To uniformly execute etching back and to fill contact bias by etching a semiconductor substrate, having a metal layer which is difficult to be worked in mixture containing NF3 and inactive gas. CONSTITUTION: In a semiconductor substrate, constituted of a lower layer 31 and a metallic layer 32 which is difficult to be worked, a tungsten layer for example, the most part of the tungsten layer 32 is etched uniformly by etching agents NF3 and Ar. Then, the remaining tungsten layer 32 and the most part of a titanium nitride layer 31 which are the lower layer are etched, and tungsten is left to be filled in a contact hole 25. The remaining parts of the tungsten layer 32 and the titanium nitride layer 31 are removed. An etching gas used in the process selectively etches Ti, TiW or TiN on W. Thus, the TiN layer 31 at a lower side is etched faster than tungsten which forms a contact filling material, and the contact filling material is made more uniform.

A cylindrical lens 11 which gives the astigmatism is fitted to an attaching groove 22 on the inside of the recessed part 21 in the direction orthogonal to the axial direction. Lenses 10 and 11 are fixed by adhesion with respective plane sides matched and are adjusted. Thus, optical axis deviation and inclination of lenses 10 an 11 are eliminated, and the deviation of the focus position from a photodetector is reduced.

Title: Exposing apparatus
Inventor: SAWADA SHIZUO
IPC: H01L21/30
Filed: 1982-07-15
Abstract: PURPOSE:To obtain an excellent pattern by the step and repeat exposure by using a theta-angle adjusting mark among the reference mark and theta-angle adjusting mark given to the X and Y axes and the mask in such a shape directed to the connecting direction of reference mark. CONSTITUTION:Connection of marks 22a, 22b of mask 21 forms an angle of 45 degrees against the X axis and an angle adjusting mark 22b is crossed by the line elements 231 and 232. At the time of positioning, the line element 231' of the angle adjusting mark 22b' exists on the extension line of the reference mark 22a and mark 22b' because expansion occurs equally in each direction if the mask expands (21'). Therefore, if positioning is carried out by stacking the mark on the exposing base on the line element 231, any rotation does not occur before and after the expansion and thereby the reference and angle adjusting marks can be stacked on the same coordinate. As a result, there is no deviation of alignment at the area near the reference mark but the deviation increases as the area is more apart from the reference mark. But in the step and repeat exposure method, the coordinate of the center of transferred pattern can be controlled accurately to below submicron order or less. Therefore, according to this structure, deviation of alignment due to expansion and compression of mask can be reduced to a large extent.

Title: Stripping method for magnetic recording medium
Inventor: KARASAWA YASUSHI
IPC: C23F1/00
Filed: 1986-05-29
Abstract: PURPOSE:To produce a reutilizable substrate capable of maintaining the initially polished roughness by dipping a plating-type magnetic recording medium in a soln. consisting of an oxidizing agent to strip off the magnetic layer and the protective layer. CONSTITUTION:The plating-type magnetic recording medium is dipped for <=about 20min in an aq. soln. contg. an oxidizing agent such as a Ce<4+> or Mn<4+> ion. In this case, when the medium is dipped for >about 20min, the nonmagnetic layer under the magnetic layer is significantly etched, surface roughness is deteriorated, and the substrate cannot be reutilized under such conditions. Since the magnetic plated film consists essentially of Co and Ni, the film must be oxidized with an oxidizing agent having an oxidation potential higher than the absolute values of the reduction potentials of respective components to dissolve the film. Although the protective film is hardly dissolved even by such oxidizing agents, the film can be simultaneously stripped off in consequence of the dissolution of the magnetic layer since the protective film has some pinholes.
