  • Patent number: 11131343
    Abstract: Provided is a resin bush capable of slidably supporting a shaft when the bush has been fitted in a housing; particularly, a resin bush suitable for use in an environment in which the effects of a difference in thermal expansion coefficients are likely to be prominent, such as a high-temperature environment, even when the housing and the shaft are made of a material such as a metal that has a different thermal expansion coefficient from that of the resin bush. In the resin bush (1), which is molded by extrusion molding, a slit (12) is formed from one axial end surface (11a) towards another axial end surface (11b). A recessed section (13) for a gate (a gate position), which is provided to the one axial end surface (11a), is provided in a position that is deviated from being symmetrical with the slit (12), at least with respect to a center axis O of a bush body (10).

  • Publication number: 20210273832
    Abstract: Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S2(i) and S2(i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S1(i) and S1(i)? obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.
