  • Patent number: 12070944
    Abstract: A liquid ejecting system includes a head unit that includes a nozzle for ejecting a liquid, a pressure chamber communicating with the nozzle, and a drive element for applying pressure fluctuation to a liquid in the pressure chamber by supplying a drive pulse, an acquisition portion that acquires output information regarding a usage condition of the head unit, a first connection portion that is communicably connected to a server through a network, a first output portion that outputs the output information through the first connection portion, a first input portion to which input information regarding a waveform of the drive pulse supplied to the drive element is input through the first connection portion. A decision portion that decides the waveform of the drive pulse supplied to the drive element based on the input information.

  • Publication number: 20200059705
    Abstract: A system for distributing a partial video portion in a series of imaged video to a user facilitates range correction of the video portion to reduce a burden on a person involved in video imaging. An information processing apparatus according to the present technology includes an information acquisition unit configured to acquire information of an in-point and an out-point specifying a partial range in an imaged video by an imaging device as a video portion to be distributed to a user, and a transmission control unit configured to perform control to transmit the information of an in-point and an out-point acquired by the information acquisition unit and the imaged video to an external device.

  • Patent number: 6160574
    Abstract: The transform arithmetic operations by spatial image transform matrixes and perspective transform matrixes to a screen surface thereon are executed on source video signal representing two-dimensional image so as to generate left-eye and right-eye video signals. It is possible to realize the stereoscopic image generation apparatus capable of setting the visual difference between a left eye and a right eye easily.

  • Patent number: 4870517
    Abstract: A cassette loading mechanism for loading a magnetic tape cassette, which has a front pivotal closure member openable for covering or exposing a front opening of the magnetic tape cassette, in a recording and/or reproducing apparatus includes a cassette holder which is movable between an eject position, at which the cassette can be inserted into or removed from the cassette holder, a lowered position vertically offset from the eject position, and a loaded position horizontally offset from said lowered position and at which cassette loading is completed. The upper portion of the cassette holder is covered with a cassette holder lid which has a recessed portion so that the front pivotal closure member may be moved to open in synchronism with movement of the cassette holder from the eject position to the lowered position. The cassette holder lid and the cassette holder are moved in unison.

  • Patent number: 4796115
    Abstract: In a cassette type recording and/or reproducing apparatus, such as an 8-mm VTR with a built-in camera, in which a tape cassette is so installed on a chassis as to have a pair of tape reels therein engaged with a pair of reel disks and then, a tape is drawn from the tape cassette by a tape loading means so as to be wound around a rotary head drum, the tape cassette is moved together with the reel disks toward the rotary head drum, after placed on the chassis on which the reel disks are provided, so that it becomes easy to make the cassette type recording and/or reproducing apparatus compact, while maintaining high tape-running stability and high recording and reproducing precisions.
