Abstract: A supporting member or first synthetic resin sheet with conductive bumps disposed at predetermined positions are superposed on a second synthetic resin sheet under the condition that the resin component of the second synthetic resin sheet is plastic deformed or the temperature thereof exceeds a glass transition temperature so that the conductive bumps are pierced into the second synthetic resin sheet. In other words, the conductive bumps are pierced vertically into the second synthetic resin sheet so as to form through-type conducive lead portions exposed to the first (supporting substrate) and second synthetic resin sheets. The through-type conductive lead portions are used to electrically connect electric devices and circuit and to connect wiring pattern layers. The conductive bumps can be precisely and densely formed and disposed by printing method or plating method. The conductive bumps can be pushed and pierced into the second synthetic resin sheet.

Abstract: A process for purifying and recovering phenol present in a mixed solution containing phenol and one or more compounds capable of forming azeotropic mixtures with phenol wherein an additive which is at least one compound belonging to the following groups 1 to 5 is added to the mixed solution and the resulting mixture is distilled:group 1: dialkylene glycols having 2-10 carbon atoms, polyalkylene glycols having 2-10 carbon atoms, and the ethers thereof,group 2: alkanediols having 2-20 carbon atoms,group 3: ethanolamine-type compounds represented by the formula (1) shown below,group 4: lactam compounds represented by the formula (2) shown below,group 5: quinoline, sulfolane, and N,N-dimethylimidazolidinone, ##STR1## wherein R.sub.1 represents an alkyl group having 1-6 carbon atoms, a cycloalkyl group having 1-6 carbon atoms, a monohydroxyalkyl group having 1-6 carbon atoms or a hydrogen atom, m represents an integer of 1-4, and X represents a hydroxyl group, an amino group or a hydrogen atom provided that R.sub.

Abstract: A capacitor network is provided for noise elimination on the input/output terminals of an electric computer or the like. A plurality of data electrodes are disposed on one surface of a dielectric substrate, and a common electrode is disposed opposite to the data electrodes on the other surface of the dielectric substrate. A pair of lead terminals are connected to each data electrode at both ends of the electrode, and at least one ground terminal is mounted to the common electrode, thereby forming a plurality of three-terminal capacitors in network.

Abstract: This disclosure is directed to an improved LC filter which includes a cylindrical ferrite member of a semi-conductor material formed with an inner bore which axially extends through its central portion, and having its grain boundary and/or at least its outer peripheral surface formed into an insulating layer, an electrode provided at least on the outer peripheral surface of the cylindrical ferrite member, and a through-conductor inserted into the inner bore of the cylindrical ferrite member.

Abstract: A high voltage variable resistor section (8) for deriving the focusing voltage and screen is attached to an open portion formed on one surface of a first case (47) which receives primary and secondary windings (2, 3) included in a flyback transformer section (1). An insulating substrate (16) on which resistor elements (9-13) included in the high voltage variable resistor section are formed in housed in a second case (15). An opening is formed in one surface of the second insulating cases (15). With this opening communicating with the opening in the first insulating case, the two insulating cases are integrated. These insulating case define insulating case means, in which a high voltage capacitor (14) for compensating cathode ray tube capacity is housed.
