An integrated circuit includes a programmable logic device and optionally a control circuit coupled to the programmable logic device. A meeting room can be viewed via a map and selected for scheduling a meeting. The query processing software receives a query, determines one or more operations that are required to be executed to fully process the query, and issues one or more commands to one or more coprocessors that are programmed to perform one of the operations, such as a table scan operation andor a lookup operation. At least a portion of the magnets are magnetized through their widths or thickness, e. This method allows production of a \u03b2-nitrostyrene compound at a high yield in the industrially-safe reaction temperature range. As a shock absorbing cover made of a silicon material is attached to an outer surface of an outer skin, even when a certain external impact is applied to the outer skin, the impact is substantially absorbed and transferred to the outer skin, so the outer skin is not easily broken, and the stuff stored in the outer skin is stably stored.
