    摘要： Wafer suitable for semiconductor deposition application can be fabricated to have low bow, warp, total thickness variation, taper, and total indicated reading properties. The wafers can be fabricated by cutting a boule to produce rough-cut wafers, lapping the rough-cut wafers, etching the lapped wafers to remove a defect, deformation zone and relieve residual stress, and chemically mechanically polishing the etched wafers to desired finish properties. Etching can be performed by immersion in a heated etching solution comprising sulfuric acid or a mixture of sulfuric and phosphoric acids. A low pH slurry utilized in chemical mechanical polishing of the spinel wafer can comprise α-Al2O3 and an organic phosphate.

    摘要： Methods using a motor, and a rolling tube or rod of sufficient strength to apply a pull force on one side of a sheet on the bed with the patient lying on the sheet to help pull up the patient on his bed or turn patients on his side with little manual effort. Patients having mobility issues under care in homes, nursing-homes or hospitals have to be regularly pulled up and turned on their sides to make them comfortable and to avoid formation of bed sores among other reasons. Currently this is done manually by nurses or caregivers. These simple but strenuous operation has been the cause of back problems for many caregivers. The current method is a way to reduce or eliminate this cause of injury to caregivers by providing a mechanized help for the operations.

    摘要： A mechanism using a motor, and a rolling tube or rod of sufficient strength to apply a pull force on one side of a sheet on the bed with the patient lying on the sheet is provided to help turn patients on his side with little manual effort. Patients having mobility issues under care in homes, nursing-homes or hospitals have to be turned on their sides often to reduce formation of bed sores among other reasons. Currently this is done manually by nurses or caregivers turning the patient by pulling up on one side of the sheet to turn the patient on his side. This simple but strenuous operation has been the cause of back problems for many caregivers. The current invention is a way to reduce or eliminate this injury to caregivers by providing a mechanized help for the patient turning operation.

    摘要： A system using a motor, and a rolling tube or rod of sufficient strength to apply a pull force on one side of a sheet on the bed with the patient lying on the sheet to help pull up the patient on his bed or turn patients on his side, to make the patient comfortable. A slide-sheet used for pull-up has a slidable underside to reduce the friction. The sheets used comprise a plurality of loops on the sides to connect to pull straps. The loops to which the pull straps are connected are chosen to apply equal force to pull or turn the patient on the sheet. Patients having mobility issues have to be routinely pulled up or turned on their sides to make them comfortable and avoid formation of bed sores. The mechanized system disclosed enables a single care giver to handle these operations.

    摘要： A pulling mechanism using a motor, and a rolling tube or rod of sufficient strength to pull a patient lying on a sheet on the bed is provided to move patients up the bed with little manual effort. In most hospitals and care facilities a common problem is that patients tend to slip down the beds causing discomfort for the patient. Patients have to be moved-up to comfortable position on the bed. Currently this is done manually by two nursing staff one on either side of the bed, with the patient on a slide sheet and pulling the patient manually up using the slide sheet. This simple but strenuous operation has been the cause of back problems for many nursing staff. The current invention is a way to reduce or eliminate this injury to nursing staff by mechanizing the pull-up operation.
