Abstract: A method and apparatus for grinding a brake pad forms inclined faces at both ends of the brake pad through a single route of movement and no grinding limit quantity is involved whether boundary lines are parallel with each other or not. The apparatus includes: a fixing portion 11 for fixing a brake pad 3; a rotary whetstone 21 having a rotation axis parallel to a friction face 3a of the brake pad 3, a grinding face of which a distance to the rotation axis increases gradually or in a plurality of steps in one direction of the rotation axis, and another grinding face of which a distance to the rotation axis decreases gradually or in a plurality of steps in the one direction of the rotation axis; and a transporter 10 for moving one of the brake pad and the rotary whetstone in relation to each other in a intersecting direction to the rotation axis.

Abstract: A method for controlling replacement of plural terminal equipment in a building management system is disclosed, in which a system can be effectively replaced, without providing any temporal apparatuses and without any obstacle on the operation. The method for controlling replacement of plural terminal equipment connected to plural points to be managed in a building, includes the steps of tabulating a connecting status showing which existing terminal equipment or new terminal equipment is used in each point to be managed and correspondence between hard addresses of the existing terminal equipment and the new terminal equipment, which correspond to the points to be managed, and switching hard addresses corresponding to the points to be managed according to the tabled connecting status of the terminal equipment and the correspondence between the hard addresses of the existing terminal equipment and the new terminal equipment.

Abstract: To provide a method of and an apparatus for grinding a brake pad in which inclined faces at both ends of the brake pad can be ground along a single route and no grinding limit quantity is generated whether the boundary lines are parallel with each other or not. The apparatus according to the present invention comprises: a fixing portion 11 for fixing a brake pad 3; a rotary whetstone 21 having a rotation axis parallel to a friction face 3a of the brake pad 3, a grinding face of which distance to the rotation axis increases gradually or in plurality of steps in one direction of the rotation axis, and another grinding face of which distance to the rotation axis decreases gradually or in plurality of steps in the one direction of the rotation axis; and a transporter 10 for moving one of the brake pad and the rotary whetstone in relation to each other in a intersecting direction to the rotation axis.

Abstract: A network system according to the present invention comprises an IP encoder connected with a plurality of clients through a network. The IP encoder compresses and encodes inputted video information, forms a packet comprising the compressed and encoded video information, and multicasts the formed video information to the plurality of clients.
