摘要:
A method of grinding semiconductor wafers including simultaneously grinding both surfaces of multiple semiconductor wafers by rotating the wafers between a pair of upper and lower rotating surface plates in a state where the wafers are held on a carrier so that centers of the wafers are positioned on a circumference of a single circle, wherein a ratio of an area of a circle passing through the centers of the wafers to an area of one of the wafers is greater than or equal to 1.33 but less than 2.0; surfaces of the fixed abrasive grains comprised in the surface plates are comprised of pellets disposed in a grid-like fashion, with the pellets provided in a center portion and pellets provided in a peripheral portion being larger in size than the pellets provided in an intermediate portion.

A housing 1 contains a plurality of signal processing units for performing signal processing corresponding to a plurality of operation modes. At a front surface 1a of the housing, an operation panel 3, a display, and a plurality of signal terminals 5a are provided, the signal terminals being located close to the display and shared by the signal processing units. A signal name memory stores signal names 11 allocated to the respective signal terminals for each of the signal processing units. A changeover switch is switched such that the signal processing units are connected to the signal processing unit corresponding to the designated operation mode in response to the operation-input operation mode designation, and the signal name corresponding to the designated operation mode is read out from the signal name memory, and is then displayed in the vicinity of the corresponding signal terminal on a display screen 4a of the display.

Provided is a multistage method and apparatus for concentrating a solution by reverse osmosis, comprising the steps and means for: maximizing the concentration of absolute in a solution in a multistage apparatus having only standard capacity pumps, including steps of providing first concentrating means for concentrating a solution to a first concentration, said first concentrating means comprising a least one concentrating unit which positioned upstream with respect to a direction in which a solution to be concentrated flows, and providing second concentrating means for concentrating the solution that has been concentrated by first concentrating means to a second concentration which is higher than said first concentrating means comprising at least one concentrating unit which is positioned downstream with respect to said direction; said concentrating units comprising consisting essentially of respective membrane modules and respective standard capacity pumps, the membrane module of the concentrating unit of said first concentrating means comprising a tight reverse osmosis membrane with a high rejection percentage sufficient to achieve a high concentration of said solution with a high flux density of solvent flowing through the membrane, and the membrane module of the concentrating unit of said second concentrating means comprising a loose reverse osmosis membrane with a lower rejection percentage sufficient to easily achieve a further concentration of said first concentrating means with a high flux density of solution flowing through the membrane.
摘要:
There is disclosed a horizontal type hydrohoist, in which slurry is forced to feed under lower pressure into feed pipes which are connected to a transport pipeline at their one ends and to a high pressure clear water pump at the others, said pump being adapted to deliver clear water under a high pressure, after which clear water is transferred under a high pressure through said feed pipe from said high pressure clear water pump, thereby transferring said slurry. This hydrohoist system presents the provision of means for preventing mixing and its spreading at the boundary portion between slurry and water within the feed pipes. More particularly, a separator which is designed not to rotate during the transfer is inserted in the aforesaid boundary portion in a manner that the separator may be transferred together with fluid, thus preventing the mixing of water with slurry as well as the resultant spreading thereof. According to a further aspect of the invention, at the completion of the slurry transfer under a high pressure, the separator is caused to be gradually slowed down to stop for the purpose of obviating a water hammer phenomenon within the pipings. In addition, after the removal of the slurry remaining around the separator by using a high pressure water, the feeding of the high pressure water is interrupted, thereby preventing mixing and its spreading at the boundary portion of water with slurry at the time of the subsequent introduction of slurry under lower pressure.
