Title: Roaster device, and burning interior protector for roaster device
Inventor: KIN AKIYOSHI
IPC: F24C3/04
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To manufacture roaster devices at smaller cost while ensuring their appreciable rapidness and safeness in burning and longer life. SOLUTION: While burning, solid fuel such as charcoal 1 put inside a grate part 30 elevates the interior wall temperature of a grate body 34 of the grate part 30.

The up and down recess binary images are synthesized, and the left and right recess binary images are synthesized, thereby forming two, i.e., up and down, and right and left recess binary images. An up and down, and a right and left judgment images are formed from the up and down, and the right and left recess binary images. A color unevenness defect is finally judged on the basis of the judgment images.
