  • Patent number: 11959198
    Abstract: A knit fabric production method includes a step of producing a knit fabric K1 from an untwisted yarn Y0 while producing the untwisted yarn Y0 by disposing a fiber bundle FB around a linear core member CP formed of a soluble polymer, falsely twisting the fiber bundle FB by using an air flow swirling in a predetermined first direction and simultaneously causing open end fibers OF to adhere to an outer circumferential surface of the falsely twisted fiber bundle FB by using an air flow swirling in a second direction opposite the first direction, and untwisting the falsely twisted fiber bundle FB.

  • Publication number: 20230271422
    Abstract: A liquid container includes a storage portion configured to store the liquid and a connection member. The connection member is provided with a liquid outlet which is inserted with a liquid introduction portion, a container-side electrical connector which makes electrical contact with an apparatus-side electrical connection unit while receive at least +Z direction force from the apparatus-side electrical connection unit, a first receiver configured to receive a first positioning portion, a second receiver configured to receive a second positioning portion, and a recess which houses a protrusion of the case. The recess and the container-side electrical connector are formed at positions which at least partially overlap each other when viewed from a Z direction in a mounting state. In the mounting state, the width of the liquid container in the Z directions is larger than the width in the Y directions and the width in the X directions.

  • Patent number: RE48556
    Abstract: A tube support member that puts a tube connected to an ink jet head and an ink tank in a bent state is provided. Accordingly, when a pulling force acts between the bent support member and the tube, a component force acting as contact force occurs at the surface that makes contact with the tube, and a high degree of friction is generated in response to this component force. The tube is thus strongly supported in a state in which the tube does not shift with the dimensions of the tube changing. Meanwhile, when the pulling force is released, the component force is also eliminated, and the tube is freed; the dimensions of the tube return to normal, and the tension is eliminated. An ink jet recording apparatus that prints using an ink jet head that is housed in a carriage is provided. The apparatus includes an ink tank that is provided outside of the carriage and is capable of being refilled.
