  • Publication number: 20240160182
    Abstract: A control system controls a control object device on the basis of control information using a control device and includes: a conversion unit configured to convert an imaging signal obtained by capturing an image generated on the basis of pre-conversion input information which is input information including the control information to the input information and to output post-conversion input information; and a transmission unit configured to transmit the control information included in the post-conversion input information to the control device.

  • Patent number: 10723826
    Abstract: Provided is a modifier for polycarbonate, comprising: a graft polymer (A) having 30 to 80 parts by mass of a main chain composed of an ethylene-based polymer (a) and 70 to 20 parts by mass of a graft chain composed of a structural unit derived from a vinyl-based monomer (b), with a total amount of the main chain and the graft chain of 100 parts by mass; and a graft polymer (B) prepared by graft polymerization of a vinyl-based monomer to a rubbery polymer, at a mass ratio (A):(B)=9 to 98:91 to 2, wherein the vinyl-based monomer (b) comprises a specific aromatic vinyl monomer and vinyl cyanide monomer.

  • Patent number: 4739938
    Abstract: An improved grinding machine of the type in which raw material to be ground is agitated in the presence of a large number of grinding media is installed in the horizontal posture. An inner tube through which raw material is introduced into the interior of a grinding tank is fitted to a raw material inlet port which is disposed on the upper outer surface of the grinding tank at the one end of the latter. The inlet port is designed in the tubular configuration extending upwardly of the grinding tank and has a flange at the uppermost end thereof to which a flange on the inner tube is fastened. The inner tube is equipped with a vibrator adapted to be periodically actuated by compressed air or the like medium of which supply is controlled by means of a control valve. The vibrator may be actuated under the effect of electromagnetic force. The inner tube is joined to a raw material feed tube via a flexible joint tube which is interposed therebetween.
