21. Other advanced stylus shapes appeared following the same goal of increasing contact surface , improving on the Shibata. 22. Nipples with a spherical contact surface to the rim that do not exhibit this tendency have been introduced. 23. A train has a very narrow contact surface between its wheels and the rail, but has adequate traction. 24. These data indicate that the critical routes involve the hands, hand and food contact surfaces and cleaning utensils. 25. The displacement is used to calculate the contact surface area, A _ s, based on the indenter geometry. 26. The needle bearings ( compact roller bearings ) were opened and cleaned and the abrasive contact surfaces were reground. 27. The large bearing contact surface and metal lubricant provide an effective method for conduction of heat from the anode. 28. When squeezed upon installation, they seal with 4 contact surfaces 2 small contact surfaces on the top and bottom. 29. The contact surfaces are not in perfect contact and offer the highest resistance and are thus heated up first. 30. The interior milk contact surface of the transfer tube shall be mechanically cleaned, sanitized and dried after each use.
