  • 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.

  • Patent number: 11951772
    Abstract: In a pneumatic tire, a tread portion includes a main groove extending in a circumferential direction, and land portions defined by the main groove. A center region is a region where a center land portion included in the land portions is closest to a tire equatorial plane. Shoulder regions are each a region between a position corresponding to 85% of a width of the belt layer in a lateral direction and an end portion of the belt layer in the lateral direction, and intermediate regions are each a region between the center region and a corresponding one of the shoulder regions. A relationship among a tire average thickness Gc in the center region, a tire average thickness Gsh in the shoulder regions, and a tire average thickness Gm in the intermediate regions is within a range of 1.05?(Gc/Gsh)?1.35 and satisfies Gc?Gm>Gsh.

  • Publication number: 20230059387
    Abstract: A mounting base (14) is fixed to an antenna (13) or an antenna bracket (15) for supporting the antenna (13). A baseband unit (11) and an RF unit (12) are fixed to the mounting base (14). The baseband unit (11) fixed to the mounting base (14) is disposed to face a back part (132) of the antenna (13) and to form a space between the back part (132) and the first enclosure (111). The RF unit (12) fixed to the mounting base (14) is disposed in the space formed between the back part (132) of the antenna (13) and the baseband unit (11) and is coupled to a waveguide flange (132) of the antenna (13). Thus, for example, in a configuration of a point-to-point wireless apparatus in which an RF unit and a baseband unit are separated, restrictions on installation space of the apparatus can be facilitated.
