    摘要： An water-based surface treatment agent used for the copper on a printed wiring board (PWB). Chemical layer formed on PWB shows excellent heat-resistance and moisture-resistance; therefore, the treated PWB preserves excellent soldability for a long time. The water-based surface treatment agent contains, as an active ingredient, a 2-arylimidazole compound represented by the following formula, ##STR1## wherein R is a hydrogen atom or a methyl group, R1 and R2 are hydrogen atoms, lower alkyl groups or halogen atoms, and R3 and R4 are hydrogen atoms, lower alkyl groups, halogen atoms, lower alkoxy groups, di-lower alkylamino groups, cyano groups or nitro groups, ##STR2## wherein R is a hydrogen atom or a methyl group, and R1 and R2 are hydrogen atoms, lower alkyl groups or halogen atoms, but excluding the case where R, R1 and R2 are all hydrogen atoms.

    摘要： A card convey device includes a first convey path, a second convey path, a third convey path, jam detector, convey controller, and card sorter. The first convey path conveys a loaded card. The second convey path is branched from the first convey path and conveys a non-defective card distributed from cards conveyed from the first convey path. The third convey path is branched from the first convey path and conveys a defective card distributed from the cards conveyed from the first convey path. The jam detector detects jam of a card occurring in each of the first, second, and third convey paths. The convey controller conveys a card through each of the first, second, and third convey paths at a predetermined speed, stops a convey operation of the card when the jam detector detects jam of the card, and reconveys the card in response to a reconvey command. The card sorter distributes the card conveyed from the first convey path to one of the first and second convey paths on the basis of non-defective/defective information of the card, and forcibly distributes a reconveyed card from the first convey path to the third convey path.

    摘要： A variable displacement piston pump of the type in which the hydraulic pressure in a pressure chamber of an output flow variable element is controlled by a proportional electro-hydraulic control valve to control the displacement of the variable element against a spring to vary the output flow within a range between a maximum output flow and a full cut-off and the output pressure or both the output pressure and the output flow of the pump are controlled electro-hydraulically through a closed loop. The variable displacement piston pump includes flow detector for generating an electric signal corresponding to the output flow of the pump, pressure detector for generating an electric signal corresponding to the output flow of the pump, and control amplifier responsive to the difference between a flow setting signal and the output signal of the flow detector to control a driving control current supplied to the proportional electro-hydraulic control valve and also responsive to the detected output pressure reaching a predetermined value to control the driving control signal in accordance with the difference between a pressure setting signal and the output signal of the pressure detector.
