Title: Seal for cylindrical surface
Inventor: WASHIDA AKIRA
IPC: F16J15/32
Filed: 1978-08-25
Abstract: PURPOSE: To effectively cool the inside cylindrical surface of a seal ring, by providing the cylindrical surface with an annular recess and a plurality of oblique recesses which communicate with the annular recess.  
     CONSTITUTION: The inside sealing surface 7 of the lip 6 of the seal ring 4 is fluid- tightly fitted on the peripheral surface of a shaft 3. The annular recess 9 is provided on the sealing surface 7. The annular recess 9 communicates with one end of the sealing surface 7 through the oblique recesses 11, 12. When a shaft 3 rotates, a fluid is caused by the screw pumping action of the oblique recesses 11, 12 to flow into the annular recess 9 from the end of the sealing surface at one of the oblique recesses and flow out from the other oblique recess. The sealing surface 7 is thus cooled by the fluid.

Abstract: PURPOSE:To prevent an impurity element from penetrating into a semiconductor region at the bottom of a contact hole by a method wherein a semiconductor substrate is introduced into a heating furnace to be used for a contact reflow process and a temperature is increased up to a reflow temperature after its introduction by using an oxidizing atmosphere. CONSTITUTION:A contact hole is made in an interlayer insulating film 14; after that, when a reflow heat-treatment process to flatten the surface of the interlayer insulating film 14 and to taper the contact hole is executed, a semiconductor substrate is introduced into the heating furnace by using an oxidizing atmosphere and at a comparatively low temperature of 700-850  deg.C. Furthermore, also an operation to increase a temperature up to 850-1100 deg.C as a reflow heat-treatment temperature is executed in the oxidizing atmosphere. By this setup, a silicon oxide film 15 with a thickness of 50-400 Angstrom is formed at the bottom of the contact hole. The silicon oxide film 15 acts as a barrier and prevent that an impurity element such as boron, phosphorus arsenic or the like contained in the interlayer insulating film 14 penetrates into an N<+> or P<+> layer 12 during the reflow heat-treatment process. As the oxidizing atmosphere, a gas containing oxygen, water vapor, ozone, trichloroethane, trichloroethylene or the like can be cited.

Abstract: PURPOSE: To uniformly disperse sodium alginate for the solidification treatment of surplus soil having high water content by adding sodium alginate to surplus soil in powdery state. CONSTITUTION: Wet wood flour 1a moistened by spraying water 17 from a nozzle 16 and a powdery mixture 2 containing sodium alginate are mixed with each other by a kneader 18, dried by a drier 24 and crushed by a crusher 31 to obtain powder 4 of a solidification treatment agent composed of wood flour 1 and sodium alginate integrally bonded with each other.
