  • Publication number: 20200040175
    Abstract: [Object] To provide a ring-shaped sealing member having both the sealing property and slidability. [Solving Means] A sealing member is formed in a ring shape and has a sliding surface. The sealing member includes: 100 parts by weight of fluorine rubber; and 0.5 to 50 (inclusive) parts by weight of a particulate resin. The particulate resin includes a compatible portion and a lubrication portion, the compatible portion having compatibility with the fluorine rubber, the lubrication portion having lubricity with respect to the fluorine rubber. A Shore A hardness measured using the sliding surface as a pressing surface is not less than 80. In this sealing member, since rubber elasticity is achieved by the fluorine rubber, a favorable sealing property can be realized. Further, it is possible to impart high slidability to the sealing member by the action of the lubrication portion of the particulate resin. Therefore, this sealing member has both the sealing property and slidability.

  • Publication number: 20200001401
    Abstract: According to a laser cutting method, a processed part is laser-cut so that the processed part doesn't drop off from a sheet-shaped workpiece. In the laser cutting method, a cut slit of a pressing protrusion, which is curved due to a laser cutting process along an outline of the processed part and then presses a peripheral surface of the processed part, is preliminarily formed around the processed part to be cut out from the workpiece. Then, the laser cutting process is carried out along the outline of the processed part. The pressing protrusion curves toward the processed part due to the laser cutting process of the processed part, and then the processed part is retained by the pressing protrusion.

  • Publication number: 20190228729
    Abstract: Provided is a display device which can quickly show an updated image to a user. A head mounted display (1) includes a display driving section (21) and a backlight (24). The display driving section secures a pause period between (i) a first display driving period during which display driving is carried out with respect to a first display region for a left eye and (ii) a second display driving period during which display driving is carried out with respect to a second display region for a right eye. The backlight does not irradiate the first display region and the second display region with light during a first period of the pause period. The backlight irradiates the first display region and the second display region with light during a second period of the pause period, the second period following the first period.
