IPC: C07C67/00
Filed: 1983-10-19
Abstract: PURPOSE:To recover almost all of methacrylic acid in an aqueous solution thereof in a cooling column in the second stage or thereafter in cooling a formed gas in the production of the methacrylic acid by the vapor phase oxidation of an iso 4C compound, by removing high-boiling impurities and substances causing scum in the first column. CONSTITUTION:A reaction gas, obtained by oxidizing an iso 4C compound, i.e. isobutylene, tert-butanol or methacrolein, in the vapor phase, and containing methacrylic acid is cooled to an aqueous solution of the methacrylic acid. In the process, the reaction product gas is cooled in a cooling column in the first stage to collect a part of the methacrylic acid and substantially the total amoun of by- products having a higher boiling point than the methacrylic acid. The uncondensed gas in the first column is then cooled in a cooling column of the second column or thereafter to collect the methacrylic acid togehter with water. On the other hand, the bottoms of the cooling column in the first stage are simply distilled to distil away the methacrylic acid with water and separate from the high- boiling by-products, and the resultant aqueous solution of methacylic acid is combined with aqueous solution from the second cooling column and thereafter. The methacrylic acid is then extracted under very stable conditions.

Title: Laminate with one side cladded with metal foil
Inventor: YANO MASABUMI
IPC: C08L61/06
Filed: 1991-08-02
Abstract: PURPOSE:To prevent a low molecular weight component residual in resin from condensation-adhering in vaporization to the surface of copper foil in a period of stacking and storing a one side copper foil cladded laminate of paper base material-phenol resin. CONSTITUTION:The varnish obtained by blending a low molecular weight component residual in resin and reacting epoxy resin into drying oil modified phenol resin is impregnated and then dried into craft paper for making prepreg, and it is superimposed and then heat-pressed with copper foil in order to manufacture a one side copper foil cladded laminate. In this way, the low molecular weight component reacts with the epoxy resin and therefore it is fixed so as not to vaporize from the laminate. As a consequence, after grinding the surface of the copper foil, adhered grinding powers can easily be removed by washing.

Filed: 1988-08-03
Abstract: PURPOSE:To simplify the constitution and to reduce the cost by providing an amplification means receiving an input signal, amplifying it at a desired amplification factor and inverting the phase and plural changeover means controlled individually switchingly. CONSTITUTION:An amplification means 113 receives an input signal 111, amplifies the signal at a desired amplification factor and inverts the phase.
