  • Patent number: 6402070
    Abstract: A bone mill has a pair of cutter units, a first cutter unit and a second cutter unit. A bone to be crushed is taken in between the first cutter unit and the second cutter unit. While passing between the first cutter unit and the second cutter unit, the bone is crushed. Each cutter unit has a plurality of disks disposed in parallel to one another at regular intervals. Each disk is provided on the periphery thereof with blades for crushing the bone. The cutter units are positioned such that the disks of the first cutter unit are fitted in the gaps between adjacent disks of the second cutter unit. Both the disks of the first cutter unit and the disks of the second cutter unit are mutually inwardly rotated. Accordingly, when a bone to be crushed is supplied between the cutter units, the bone is taken in by and between the disks of the first cutter unit and the disks of the second cutter unit, both sets of disks being mutually inwardly rotated.

  • Patent number: 5937391
    Abstract: A service system in an online shopping mall established through a network realizes an improvement of a service to a customer by not having to carry a magnetic card and shortening a time from issuing points to redeeming points. To attain the objects of the system, a points issuing unit issues points corresponding to the purchase amount of a customer. A points storage device stores the number of points accumulated by the customer. A points redeeming unit reduces a purchase amount of the customer as points to be redeemed. A points issue ratio and a points redeeming ratio can be set for each shop forming part of the online shopping mall.
