    摘要： A method for producing polyamides, and to a method for producing primary polycondensates which are intermediates for polyamide production. More precisely, the invention relates to a method for producing primary polycondensates, which comprises a step of polycondensing a dicarboxylic acid component having a terephthalic acid content of from 60 to 100 mol % and a diamine component in which the amount of 1,9-nonanediamine and/or 2-methyl-1,8-octanediamine falls between 60 and 100 mol %, in the presence of water of being from 15 to 35% by weight, at a reaction temperature falling between 250.degree. C. and 280.degree. C. and under a reaction pressure (P) that satisfies the following formula (1):P.sub.0 .gtoreq.P.gtoreq.0.7 P.sub.0 (1)where P.sub.0 indicates the saturated vapor pressure of water at the reaction temperature, to form a primary polycondensate, followed by a step of taking the resulting primary polycondensate as formed in the previous step out of the reactor in an atmospheric environment while it is at a temperature within the same range as in the previous step and has a water content within the same range as in the previous step. The invention further relates to a method of polymerizing the primary polycondensate prepared previously into a polyamide having an increased molecular weight.

    摘要： A charging circuit comprises a main circuit for charging a battery and a power unit connected to an electric power source. The main circuit and the power unit are connected through a connector to each other. The power source transformed by a transformer located at the power unit is supplied to the connector through a contact of a direct current relay. After alternating current is introduced to the main circuit from the power unit, the alternating current is rectified by a diode bridge. The direct current from the diode bridge is supplied to the battery through a control circuit. When the battery is charged sufficiently, the control circuit outputs an instruction signal to a diode portion of a photo-triac connected between an output terminal of the diode bridge and the control relay. When the instruction signal is transmitted to the diode portion, a triac portion of the photo-triac, which is connected between one of an input terminal of the diode bridge and the connector, outputs another instruction signal to the relay located at the power unit for opening the contact through the connector.

    摘要： The present invention provides a polyamide resin composition not only having an appropriate melt viscosity despite addition of a conductive filler thereto but also having excellent moldability, conductivity, low-temperature impact resistance, and fuel barrier properties. The present invention is a polyamide resin composition containing specific amounts of a polyamide, a modified resin, and a conductive filler. The polyamide contains: dicarboxylic acid units containing 50 mol % or more of terephthalic acid units and/or naphthalenedicarboxylic acid units; and diamine units containing 60 mol % or more of aliphatic diamine units having 4 to 18 carbon atoms, and has terminal amino groups in an amount of 5 to 60 μmol/g. The modified resin has been modified with an unsaturated compound having a carboxyl group and/or an acid anhydride group. In the polyamide resin composition, a difference between the number of moles (MI) of the terminal amino groups of the polyamide and the number of moles (MII) of the carboxyl groups and the acid anhydride groups of the modified resin in 1 g in total of the polyamide and the modified resin is −5.0 μmol or more and less than 4.0 μmol, and the number of moles (MII) is more than 4.0 μmol.
