The microwavable shipping and / or retail package described here for heating food includes a material suitable for use in a microwave oven. The food disposed in the package is preferably at least partially raw. Taking into account the water content of the food, enough liquid is present in the package for the food to be cooked in a steam atmosphere which develops in the package when heated in a microwave oven. The package has a one-way valve in a wall, which opens automatically to the outside when there is an internal excess pressure, then closes again automatically after the pressure drops, thus limiting and / or reducing the vapor pressure that develops in the package during heating in a microwave oven. The valve membrane may automatically open and automatically close until the membrane deforms during heating, thereby causing said valve to remain open.

A keybar or clamping bolt with a high-resistivity coating to protect an electric machine. The coating engages the laminations, flanges and frame rings and forms a part of electrical circuits through which harmful eddy currents circulate. One class of eddy currents, viz., core-fault currents, due to edge burrs or insulation defects, are forced to flow through this coating. The high resistance of the coating weakens the fault currents, preventing creation of hotspots that can cause core failure. Such coated keybar is in inexpensive alternative to traditional recoating and / or core-fault detection. Another class of eddy currents, viz., keybar currents, caused by over-fluxing, are also forced to flow through this coating. The high resistance of the coating weakens the keybar currents, so prevents core-end overheating. A coated keybar also allows the machine to operate at higher leading power factor. It also prevents core-decompression hence protects the machine against loose laminations.

The method comprises the following steps: when a memory compression triggering condition is met, performing memory compression on a target memory page in a memory space to obtain a compressed target memory page; determining the compression rate of the target memory page according to the data volume of the target memory page before and after compression; if the compression rate indicates that the target memory page meets a writing condition, writing the compressed target memory page into a memory compression space in the memory space; and if the compression rate indicates that the target memory page does not meet the writing condition, stopping writing the target memory page into the memory compression space. By setting the write-in condition and refusing to write the memory pages which do not meet the write-in condition intothe memory compression space, the useless decompression process of the CPU is reduced, and the overall compression ratio of the memory compression space is further improved.
