Title: Production of aromatic polyamide
Inventor: IWAKIRI MASAMITSU
IPC: C08G69/32
Filed: 1986-02-13
Abstract: PURPOSE:To obtain the titled high-quality uniform polymer having a high m.p. and a high degree of polymerization and being excellent in strength, modulus, heat resistance and flame retardancy, by polymerizing p-phenylenediamine with terephthaloyl chloride by using a specified solvent system. CONSTITUTION:CaCl2 preheated, if necessary, to about 200 deg.C is heated for 5hr or longer at 250-500 deg.C in air or an inert gas such as N2 and cooled to about 80 deg.C in an inert gas such as N2 under the exclusion of moisture. The CaCl2 heat-treated under the above-specified conditions is dissolved in an N- substituted solvent (e.g., N-methyl-2-pyrrolidone) so that the concentration may be 0.30-0.90mol/l. About equimolar amounts of p-phenylenediamine and terephthaloyl chloride are dissolved in this solution so that the resulting solution may have a monomer concentration as high as 0.40-0.50mol/l, and the monomers are polymerized at -10-70 deg.C under an applied high shearing force.

Title: Dry etching method
Inventor: HAYASHI SENICHI
IPC: C23F4/00
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a dry etching method which is designed to detect an etching end accurately and which exhibits superior productivity. SOLUTION: This dry etching method is designed to cause a mass spectrometer to detect AlFx, which is a reaction product, one minute after the start of a dry etching process of an Al2O3 film, the processing of which comes after an SiO2 film has been completely dry-etched. Since it takes 7.5 minutes for the Al2O3 film to be completely removed by dry etching, a RF power supply is turned off to stop the dry etching, whereby the Al2O3 film is left unetched.

Filed: 1993-02-17
Abstract: PURPOSE:To carry out size reduction to the extent of the diameter of a code by laminating a thin film polarizer and a thin film analyzer via a magnetic optical effect element. CONSTITUTION:In the first optical fiber 1, a core 4 and a clad 5 are provided while a thin film polarizer 6 is laminated on a core 4 end face of approximately 0.3mum diameter. In the second optical fiber 2, a thin film analyzer 7 is laminated on the end face with being inclined so as to make 45 deg. with the polarizer 6 via a magnetic optical effect element 3. Random light enters the polarizer 6 passing through the optical fiber 1 from a light source to be converted into the linearly polarized light. As the linearly polarized light passes through the element 3 and the analyzer 7, the element 3 rotates the polarized face by a rotation angle in proportion to the magnetic field width around a cable while the analyzer 7, which inclines at 45 deg. to the polarizer 6, emits the light of proportional amount to the width of the magnetic field. This linear polarized light enters a light receiving part via the optical fiber 2 so that proportional signal to the width of the magnetic field, in other words, to the amount of the current is detected. In this way, the size is reduced to the extent of the diameter of the cord as the polarizer 6 and the analyzer 7 are used.
