1. A method for positioning the foot, comprising the steps of:
providing a foot device consisting of a knee belt adapted to be secured on a user below the knee on a leg, the knee belt comprising a double D-ring buckle at one end thereof for adjusting the fit of the belt to the user’s leg; a loop firmly attached to the knee belt at approximately 3 inches from the double D-ring buckle end of the belt, wherein the loop is attached to the belt via a rivet or stitching; a 6 inch wide therapeutic rubber band having a length of approximately 32 inches and first and second ends;
placing the knee belt on the user below the knee;
tightening the belt for a firm fit;
attaching a first end of the therapeutic rubber band to a shoe adjacent the toes;
wrapping the band under the shoe from the inside of the shoe around to the outside of the shoe such that the band is evenly spread on the outside of the shoe in a position that provides good toe lift and rotations of the foot such that the foot will sit flat on the floor; and
extending the second end of the band to the loop and attaching it thereto.
2. The method of claim 1, wherein the device is adapted to be worn on either the left or right leg.
3. The method of claim 1, wherein the therapeutic band is slid forward on the foot to achieve greater toe lift.
4. The method of claim 1, wherein the band can be changed to thin, medium, heavy and extra heavy in order to increase or decrease the strength of the band to provide the correct amount of toe lift.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1-15. (canceled)
16. A turbine fuel pump, comprising:
a casing for accommodating an electric motor;
a housing provided to the casing, the housing comprising an annular passage between inlet and outlet ports; and
an impeller rotatably arranged in the housing, the impeller comprising blades arranged on an outer periphery to extend in a radial direction of the impeller and feeding fuel through the passage while the blades are rotated by the electric motor,
each blade including a plate body of substantially rectangular section, the plate body comprising a front face located on the forward side of the impeller, a rear face located on a rearward side of the impeller, and a pair of side faces located between the front face and the rear face,
each blade comprising a chamfer arranged on the root side of the blade to extend in the radial direction of the impeller, the chamfer being obtained by slantly cutting a comer between the side face and the rear face of the blade, the chamfer having a predetermined length, wherein the predetermined length is (\u2156 to \u2157)\xd7L, where L is a radial length of the passage.
17. The turbine fuel pump as claimed in claim 16, wherein the predetermined length of the chamfer is ( 920 to 1120)\xd7L.
18. The turbine fuel pump as claimed in claim 16, wherein the chamfer comprises a root-side portion and a head-side portion, wherein the root-side portion has a substantially constant chamfer width and a predetermined length, and the head side portion has a chamfer width gradually reduced from a head of the root-side portion.
19. The turbine fuel pump as claimed in claim 18, wherein the predetermined length of the root-side portion is (\u2155 to \u2158)\xd7T, where T is an overall length of the chamfer.
20. The turbine fuel pump as claimed in claim 19, wherein the predetermined length of the root-side portion is (\u2156 to \u2157)\xd7T.
21. The turbine fuel pump as claimed in claim 20, wherein the root-side portion has a predetermined angle of inclination with respect to the side face of the blade, wherein the predetermined angle is 30 to 70\xb0.
22. The turbine fuel pump as claimed in claim 21, wherein the predetermined angle of inclination of the root-side portion is 40 to 60\xb0.
23. The turbine fuel pump as claimed in claim 22, wherein the predetermined length of the chamfer is \xbd\xd7L, the predetermined length of the-root-side portion is \xbd\xd7T, and the predetermined angle of inclination of the root-side portion is 50\xb0.
