Abstract: A pneumatic tire seater for seating a tubeless tire on a rim has an advanced rapid air release (RAR) valve mounted on a tank suitable for containing pressurized air. A nozzle is mounted on one end of the RAR valve, and the other end of the valve is in unconstrained pneumatic communication with the interior of the air tank.

Abstract: A glass cutter is provided which can form, using a wheel, a uniform crack in glass even when a projection or an earlier-formed scribe line is present on the glass. When the wheel is moved on the glass, a fracture layer is formed causing a rib mark to be formed below the fracture layer and a crack to be formed below the rib mark. To cut the glass, the crack is required to be formed uniformly. Applying a force to resist the rotating force of the wheel makes it possible to form a uniform crack even when a projection is present on the glass. This improves glass cutting yield.

Abstract: The scribing wheel achieves increase in its longevity and ensures high strength in end face of segmented substrate obtained by severing brittle material-made substrate scribed by the scribing wheel. Disc-shaped scribing-wheel base material in use is so designed that mid-portion of disc periphery has the largest diameter. Diamond film is formed on the periphery by CVD method. The periphery is ground in the middle so that a plane including a circle defined by ridge line becomes perpendicular to the central axis of the scribing wheel. This helps reduce the roughness of ridge part. When the scribing wheel is used for scribing on brittle material-made substrate, upon severing of the scribed substrate, the end face of the segmented substrate can be made with greater accuracy and higher strength. The scribing wheel suffers little from abrasion at its ridge part even under continuous scribing, and thus enjoys longer operating life.
