摘要:
An input/output unit includes: input/output subunits each including an input/output card that has front-side connectors, which are engaged with back-unit connectors on a back unit of a control device, mounted on a front edge of a substrate and has mounted on a rear edge of the substrate, rear-side connectors to be engaged with connectors of field devices and a card holder that has at a front side, guide shafts to be inserted into guide holes of the back unit and holds the input/output card; and a case which is formed with slots into which the input/output subunits are inserted with a gap, which is formed on a front plate with a long hole into which the back-unit connectors are inserted with a gap and with shaft holes through which the guide shafts are penetrated from inside with a gap, and which is attached to the back unit.
摘要:
A substrate for liquid chromatography comprising a spherical particle of highly cross-linked polymer which is produced from (a) 100 parts by weight of a monomer of vinyl ester, acrylate or methacrylate, these esters having a long alkyl chain, if desired, together with a comonomer copolymerizable with the monomer and (b) 10 to 80 parts by weight of a cross-linking agent copolymerizable with the monomer and having at least two functional groups, and a process for isolating and purifying a fat-soluble substance, for instance, a lower alkyl ester of eicosapentaenoic acid or docosahexaenoic acid by means of the liquid chromatography on the substrate.
摘要:
A speaker apparatus comprises a slit structure, wherein the slit structure including a plurality of plate-shaped parts each of which extends so that a plurality of slits are formed, a plurality of fold-back parts each of which is folded back from an end of the plate-shaped part on the side of the speaker toward a side of the front surface of the housing, so that the plurality of slits are formed, and a drain part that is arranged on a side of one of the two side surfaces of the housing, and wherein each of a plurality of grooves formed by the plurality of plate-shaped parts and the plurality of fold-back parts communicates with the drain part and is inclined so that, in a posture of the slit structure when the operation panel is operated, liquid led from the plate-shaped parts flows to the drain part.
