Title: Vertical bearing device
Inventor: KWANGIK NA
IPC: H02K7/08
Filed: 2018-02-20
Abstract: Vertical bearing device 10 has a thrust collar 21 that rotates with a vertical rotating shaft member 12. The thrust collar contacts a thrust bearing 23 and a radial journal bearing 25. Casing 24 surrounds the shaft and is formed into a container shape defining with a base plate 22 an oil chamber with an upper and a lower chamber 46, 47. Cooling part 26 is provided integrally on a radially outer side of the casing and has a lubricating oil passage part 51 exposed from the casing. This allows lubricating oil to flow from the upper chamber to the lower chamber, cooling the oil before it is recirculated in the casing. A cover 27 outside the casing defines an airflow space. The cooling part has an air inlet into which cooling air flows, which is positioned within a preset range (fig. 22). The air inlet is positioned between 1/4h above and 5/4h below the upper end of the oil chamber and within 2a of the outer peripheral face of the casing. h is the distance from the upper to the lower end of the oil chamber and a is the shortest distance between the casing and the cover.

Title: Liquid crystal panel drive method
Inventor: CHUNPENG GUO
IPC: G09G3/36
Filed: 2016-02-25
Abstract: A liquid crystal panel drive method, characterized in that the drive method comprises: (A) applying a first overdrive voltage to a common electrode of each pixel of a liquid crystal panel at the moment of conversion to a touch scanning time period from a normal display time period of a current frame (S100); and (B) applying a second overdrive voltage to the common electrode of each pixel at the moment of conversion to the normal display time period of the next frame from the touch scanning time period of the current frame (S200). According to the method, a time of reaching a pre-set level voltage of a common electrode can be shortened, so that the problems of poor display and touch of an in-cell touch screen caused by signal abnormity at the moment of mutual switching between touch scanning and normal display can be effectively solved.
