  • Patent number: 8991965
    Abstract: A liquid ejecting apparatus includes: a transport roller that transports a medium in a transport direction; a head that moves in a direction orthogonal to the transport direction, and ejects liquid to the medium; a cutter that moves in the transport direction and the orthogonal direction and cuts a part of the medium positioned in a predetermined range from a first position to a second position in the transport direction; and a controller that performs a first process of forming an image on the medium by controlling the transport roller to transport the medium in the transport direction and controlling the head moving in the orthogonal direction to eject the liquid, and performs a second process of forming a cutting line on the medium by controlling the cutter to cut the part of the medium over the predetermined range during the first process.

  • Patent number: 4479879
    Abstract: A process for dewatering aqueous sludges of organic nature by adding to the sludge a cationic organic flocculant to effect a first stage agitation of vigorous intensity, and then adding thereto an anionic organic flocculant to perform a second stage agitation of mild intensity and subjecting the thus formed flocs to a dewatering operation, which process comprises the use of a cationic organic flocculant composed of any combination of A- and B-components, wherein the A-component consists of one or more polymers selected from the group consisting of A.sub.1 - and A.sub.2 -components, in which the A.sub.1 -component consists of polymers having a structural unit of vinylimidazoline or partially hydrolyzed products thereof and the A.sub.
