  • Publication number: 20240082560
    Abstract: A connector (1) is constituted by a first member (10) and a second member (40). The first member (10) has a male connecting portion (11) at a first end and a screwing structure (26) at a second end. The male connecting portion (11) is inserted into a female connecting portion (41) of the second member (40). A first engagement structure (15) is provided on the first member (10), and a second engagement structure (45) is provided on the second member (40) so as to be able to abut against the first engagement structure (15) in the circumferential direction. When a rotational force of a predetermined value or greater is applied to the first member (10) in a tightening direction (R1) of the screwing structure (26), one of the first engagement structure (15) and the second engagement structure (45) is plastically deformed by the other, so that the first member (10) is then rotatable in both forward and reverse directions relative to the second member (40).

  • Patent number: 8292384
    Abstract: A liquid droplet ejection device includes a recording section, a moving section, and a driving signal supplying section. In the recording section, plural liquid droplet ejectors are arrayed, each liquid droplet ejector has a driving element, and ejects a liquid droplet onto a recording medium in response to a driving signal being supplied to the driving element. The moving section moves the recording section and the recording medium relative to one another in a direction intersecting the array direction of the liquid droplet ejectors. The driving signal supplying section generates, when plural types of liquid droplets having different droplet volumes are ejected onto the recording medium while the recording section and the recording medium are moved relatively, the driving signals such that, the smaller a droplet volume of a liquid droplet, the faster the ejection speed of the liquid droplet.
