What is claimed is:
1. A buffing pad for use on a rotary powered buffer apparatus comprising:
a resilient buffing pad body including a working face and a backing portion, said working face having an outer periphery and a central portion; and
an outward slanted surface provided at said central portion of the pad for facilitating outward dispersion of buffing compound onto a friction area of the pad.
2. The buffing pad in accordance with claim 1, wherein said outward slanted surfaces further comprise:
a hollowed out frustro-conical shape through the center of the pad with the wider part of the conical frustum at the working face of the pad and the narrower portion at the rear or mounting surface of the pad, which prevents build up and saturation of compound at the center of the pad by utilizing centrifugal force to spread buffing compounds outward from the center.
3. The buffing pad in accordance with claim 1, wherein said resilient buffing pad body is made of a foam material.
4. The buffing pad in accordance with claim 1, wherein the peripheral edge of same is rounded.
5. The buffing pad in accordance with claim 1, wherein said backing portion further includes a hook and loop fastener for attachment to a rotary powered buffer apparatus.
6. A buffing pad for use on a rotary powered buffing apparatus comprising:
a resilient buffing pad body including a working face and a backing portion, said working face having an outer periphery and a central portion; and
a frustro-conical surface formed at said central portion with the wider portion of the conical frustum at the working face of the pad, whereby build-up of material at the center of said pad is prevented by said frustro-conical surface biasing any buffing material in the center toward movement onto the friction area of the pad.
7. The buffing pad of claim 6 wherein the outer periphery has a rounded edge.
8. The buffing pad of claim 6 wherein the resilient buffing pad body is made from a foam material.
9. The buffing pad of claim 6 wherein a hook and loop fastener material is attached to the backing portion for attachment of the pad to the rotary powered buffer apparatus.
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. A base station comprising:
a processor configured:
to perform communication with a terminal by using a cell defined as a combination of a frequency and an area reachable by a signal transmitted from the base station,
to specify, for each of cells, a first area in which disconnection of communication with a terminal occurs more frequently as compared to another area, and
to control handover that changes a current cell of a first terminal to another cell, based on information on the specified first area and the current cell of the first terminal, and a position, moving speed, and moving direction of the first terminal; and
a memory configured to store information on areas and the cells.
2. The base station of claim 1, wherein
the processor determines whether or not the first terminal is expected to enter one of the specified first areas that corresponds to a cell having a frequency equal to that of the current cell of the first terminal, based on information on the one of the first areas and the position and moving direction of the first terminal;
the processor calculates a time needed for the first terminal to enter the one of the first areas, based on information on the one of the first areas and the position and moving speed of the first terminal; and
the processor causes the first terminal to perform handover thereof when it is determined that the first terminal is expected to enter the one of the first areas and the calculated time is less than a first threshold.
3. The base station of claim 1, wherein
the processor obtains a first report transmitted from each of terminals each time communication for the each terminal is disconnected, the first report including positional information of the each terminal at a time when the communication is disconnected; and
the processor counts, based on the obtained first report, a count value defined as a number of times the communication is disconnected, for each mesh code, and sets, as the first area, an area corresponding to a mesh code for which the count value is equal to or greater than a second threshold.
4. The base station of claim 3, wherein
the processor groups a plurality of mesh codes for which the count value is equal to or greater than the second threshold and whose corresponding areas form a continuous area, into a same group.
5. The base station of claim 4, wherein
the processor sets, as the first area, a rectangular area including all of areas corresponding to mesh codes included in the same group.
6. The base station of claim 1, wherein
the processor performs handover of the first terminal to a cell that includes neither the first area of the base station nor the first area of adjacent base stations adjacent to the base station.
7. The base station of claim 2, wherein
the processor cyclically obtains, from each terminal included in an area of the base station, a second report including a position, moving speed, and a moving direction of the each terminal; and
when a transmission source terminal that has issued the obtained second report is connected to a cell including the first area of the base station, the processor determines whether or not the transmission source terminal is expected to enter the first area of the base station.
8. The base station of claim 7, wherein
the processor sets a cycle of the second report transmitted by the transmission source terminal connected to a cell including the first area of the base station, at a value shorter than a cycle of the second report transmitted by the transmission source terminal that is not connected to a cell including the first area of the base station.
9. The base station of claim 1, wherein
the processor determines whether or not the first terminal is expected to enter the first area, based on information on one of the first areas whose frequency is equal to that of the current cell of the first terminal, and the position and moving direction of the first terminal;
the processor calculates, based on the position and moving speed of the first terminal, a time needed for the first terminal to pass through the first area; and
the processor excludes the first terminal from targets of handover when it is determined that the first terminal is expected to enter the first area and the calculated time is less than a second threshold.
10. A handover control method comprising:
specifying, for each of cells, a first area in which disconnection of communication with a terminal occurs more frequently as compared to another area, the each cell being defined as a combination of a frequency and an area reachable by a signal transmitted from the base station; and
controlling handover that changes a current cell of a first terminal to another cell, based on information on the specified first area and the current cell of the first terminal, and a position, moving speed, and moving direction of the first terminal.
