77results about How to "Reduce contact surface area" patented technology

To provide particles that are free of particle blocking, that have a particle shape close to a perfect sphere, that are also industrially advantageous and allow easy reaction control, and that have exceptional properties such as dispersion stability, stability during particle isolation, and physical stability. These silica-coated silicone rubber particles have silicone rubber particles, and a coating layer that covers the surface of the silicone rubber particles and that comprises silica particles. The coating level of the coating layer is from 2.0 * 10-9 to 3.2 * 10-6 kg / m<2>, and the sphericity is from 0.8 to 1.0.

A hand-held surface preparation apparatus comprising a frame, a hollow semi-circular shaped housing member connected to said frame, a drive housing connected to said housing member, a motor secured to said drive housing aligned directly over said hollow semi-circular shaped housing member, a roller rotatably positioned inside of the semi-circular shaped housing member in communication with said motor, front and rear guide handles extending from said frame, and removably connected front and rear debris guards.

A radial sliding bearing provided with a sliding bearing (1), an inner ring (2), and an outer ring (3), the inner ring (2) is made of melt-cast metal and the outer ring (3) being constituted by an article molded from a resin composition, the inner ring (2) comprising a concavely curved surface (2a) on part of the axial direction of the outer circumference and a bearing hole (4) for mating with a support shaft on the inner circumference, the outer ring (3) having a convexly curved surface (3a) that contacts and slides against the concavely curved surface (2a) on the outer circumference of the inner ring (2) along part of the axial direction of the inner circumference, and the inner ring (2) and the outer ring (3) relatively rotating without contacting each other apart from the contact between the convexly curved surface and the concavely curved surface.

A video laryngoscope and elongate laryngoscope insertion section for a video laryngoscope, comprising a viewing port through which an imaging device within the insertion section can obtain images of a larynx, the insertion section extending between a distal end for insertion into a subject and an opposite proximal end, and having an inferior surface and an opposed superior surface, wherein the insertion section comprises a proximal region where the insertion section extends through a subject's teeth in use, a distal region extending to the distal end and an intermediate region therebetween, wherein the inferior surface of the insertion section comprises or consists of a curved region which extends from the proximal region through the intermediate region to the distal region, wherein the curved region of the inferior surface is continuously longitudinally curved along the length of the longitudinally curved region and wherein the longitudinal curvature of the curved region of the inferior surface varies in the intermediate region. Markings on an elongate laryngoscope insertion can be used to monitor depth of insertion and to indicate a path by which an endotracheal tube should be inserted.
