Title: Production of copolymer
Inventor: EBINA YOSHIAKI
IPC: C08F220/22
Filed: 1981-02-19
Abstract: PURPOSE: The emulsion copolymerization of perfluoroacrylic acid or its derivative is conducted by allowing its copolymerization to follow home polymerization of another fluorine-containing polymerizable monomer to give a copolymer.  
     CONSTITUTION: At least one of fluorine-containing monomers other than perfluoroacrylic acid or its derivatives such as tetralfluoroethylene is polymerized. At the start or after continuation for a certain time of the polymerization, perfluoroacrylic acid or its derivative such as perfluoroacrylic acid is added, further, a radical polymerization initiator and, when necessary, a polymerization degree regulator are added to effect the copolymerization at about 30W120°C. When the reaction pressure begins to drop, a prescribed amount of a fluorine- containing polymerizable monomer is added to continue the polymerization until the pressure comes down to about 10kg/cm 2 . At this point, the reaction is stopped to give the objective copolymer.  
     EFFECT: The reaction heat is easily removed, posttreatment is not needed and the polymerization rate is high.

Title: Projection exposure device
Inventor: NISHIGUCHI KATSUNORI
IPC: H01L21/30
Filed: 1985-02-08
Abstract: PURPOSE:To enable patterns of the same shape except that dimensions are different to be exposed by projection on the substrate at a desired position in a relatively short time, by a method wherein the magnification for enlargement-reduction of mask patterns is enabled to be arbitrarily set within a restricted range at every projection exposure. CONSTITUTION:A photo mask 2 is held by a mask supporting base and receives irradiation beams 4 coming out of an exposure optical system 3. This beam passes through an image-forming projection optical system which can control the magnification of enlargement-reduction with a control system 8, forming a photo mask image on the plane substrate 1 held on the plane substrate supporting base 7, and exposes it within a specific area. Thereafter, the whole substrate is exposed to light by the step and repeat system wherein the substrate 1 is moved to next exposure positions by driving a servomotor and the like for said supporting base by means of the control system 8 and is repeatedly exposed. This manner enables patterns of the same shape and different dimensions to be exposed by projection on a plane substrate of Si single crystal at its desired position in a short time.

Title: Magnetic head and its manufacture
Inventor: ITO KEIKO
IPC: G11B5/187
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of recording and reproducing output due to leakage of magnetic flux from the vicinity of a magnetic reluctance part by fitting a nonmagnetic electroconductive member to the magnetic reluctance part. SOLUTION: In the magnetic head having a regulated width for a magnetic track by partly eliminating a magnetic gap 23 and magnetic members 21 and 22 adjacent to this gap and forming the magnetic reluctance parts 24, the nonmagnetic elctroconductive member 28 is fitted to the magnetic reluctance parts respectively. Thus, since these magnetic reluctance parts 24 are magnetically shielded by the nonmagnetic electroconductive members 28, the leakage of magnetic flux from the vicinity of the magnetic reluctance parts 24 is suppressed. Moreover, since the nonmagnetic electroconductive members 28 become high resistance due to overcurrents generated at the time of passing the magnetic flux through the members, the leakage of magnetic flux from these surfaces is drastically reduced.
