  • Patent number: 10343245
    Abstract: A liquid drainage mechanism drains oil (liquid) from a Y-axis slider that moves along a predetermined path. The liquid drainage mechanism includes an outflow hole and a nozzle flow passage that are provided in a C-axis rotary mechanism and configured to flow the oil in a stator, a nozzle configured to move integrally with the Y-axis slider and discharge the oil, and a Y-axis guide member configured to guide the Y-axis slider. The nozzle is disposed at a position that is close to but not in contact with the Y-axis guide member, and the nozzle discharges the oil so that the oil reaches the Y-axis guide member.

  • Patent number: 10312507
    Abstract: The initial charge/discharge efficiency and cycle characteristics of a non-aqueous electrolyte secondary battery that contains a silicon material as a negative-electrode active material are improved. A negative-electrode active material particle (10) according to an embodiment includes a lithium silicate phase (11) represented by Li2zSiO(2+z) {0<z<2} and silicon particles (12) dispersed in the lithium silicate phase (11). A lithium silicate constituting the lithium silicate phase has a crystallite size of 40 nm or less. The crystallite size is calculated using the Scherrer equation from the half-width of a diffraction peak of a (111) plane of the lithium silicate in an XRD pattern obtained by XRD measurement of the negative-electrode active material particle 10.
