  • Publication number: 20090234482
    Abstract: When inputted with a loading plan table file including item names to be loaded into a process line and the number of item names to be loaded, an equipment loop is executed for each equipment. The equipment loop includes an item name loop and a machine-type loop. In the item name loop, a condition group representing a combination of machine types is acquired for each process. In the machine-type loop, distribution factor data for each machine type is acquired for each condition group, and data of a required number of pieces to be processed by process and machine type, the data to be assigned to each machine type on the basis of the distribution factor data. Based on this data of the number of pieces to be processed by process and machine type, machine-type load factor data for each machine type is determined for each equipment.

  • Publication number: 20080255599
    Abstract: An acupuncture needle gives skin a favorable stimulus without invading the skin when in contact with or pressed against the skin. The acupuncture needle includes a base plate and projections formed on a surface of the base plate integrally therewith. Each of the projections have elasticity and includes a base portion and a substantially cylindrical head portion formed on the base portion. The head portion has a flat top surface substantially parallel to the surface of the base plate and a side perpendicular to the surface f the base plate. The base portion has an inwardly depressed external curved line in a central vertical section and a diameter in a transverse cross section gradually becoming larger toward the surface of the base plate. The projections sway in a direction substantially parallel to the skin when the acupuncture needle is in contact with or pressed against the skin.

  • Patent number: 6638141
    Abstract: A polishing apparatus for CMP is provided. Heating means heats the substrate held by the holder. Temperature detecting means detects temperature of the heating means. Temperature compensating means sets temperature compensation values in such a way that a polishing rate is approximately uniform over a whole polishing surface of a polishing film. The polishing film is formed on the substrate. The heating means is controlled in such a way that the temperature detected by the temperature detecting means corresponds to the temperature compensation values. The substrate is heated by the heating means while controlling the heating means with the controller within a polishing period of the film. The heating means may comprise heaters arranged to cover the substrate and controlled by a controller.

  • Patent number: 6004304
    Abstract: The present invention relates to a subcutaneous needle in which a needle body and an adhesive tape are reliably secured together with a resin material enabling the operation to be correctly executed, and a method of producing the same. The subcutaneous needle is constituted by an adhesive tape, a separate paper, a needle body and a resin material. The adhesive tape has a hole formed in the central portion and has an adhesive surface on one side thereof. The separate paper has a hole in the central portion and is stuck on the adhesive surface of the adhesive tape. The needle body is bent in an L-shape and its top end side protrudes penetrating through the holes of the adhesive tape and of the separate paper. The base end side of the needle body is arranged nearly in parallel with a nonadhesive surface of the adhesive tape. The resin material is injection-molded onto the nonadhesive surface of the adhesive tape so as to cover and secure the base end side of the needle body.
