摘要:
Disclosed is a water-absorbent polymer composite and composition thereof comprising a water-absorbent polymer particle and two or more fibers, wherein said polymer particle has a substantially spherical shape, at least one of said two or more fibers is partially wrapped in the polymer particle and partially exposed to outside the particle, and at least one of said two or more fibers is unwrapped in the polymer particle and partially adhered to a surface of the polymer particle. This water-absorbent polymer composite is characterized in that the fibers are stably fixed to the water-absorbent polymer not only in dry but also in wet through water absorption for swelling, the water-absorbent polymer content can be enlarged relative to the fibers, the polymer can be uniformly fixed to the fibers, the composite is flexible and can be thinned, opened and mixed with any other material uniformly.

Disclosed is a method for preparing a water-absorbent polymer composite comprising the steps of contacting a droplet containing a solvent and said polymerizable monomer before polymerization and/or under polymerization with first fibers fed through a first supply port of said reactor in a gas phase, proceeding with polymerization of said polymerizable monomer, contacting the resultant droplet containing said solvent, the polymerizable monomer under polymerization and said first fibers with second fibers fed through a second supply port of said reactor in a gas phase, and proceeding with further polymerization of said polymerizable monomer to form said water-absorbent polymer composite. The water-absorbent polymer composite prepared by the method is characterized in that the fibers are stably fixed to the water-absorbent polymer not only in dry but also in wet through water absorption for swelling, the water-absorbent polymer content can be enlarged relative to the fibers, the polymer can be uniformly fixed to the fibers, the composite is flexible and can be thinned, and it can be opened by itself and can be uniformly mixed with any other material.

The invention saves resources and energy. A cleaning/fluid-feeding head integrates a cleaning head portion and a fluid-feeding head portion. The cleaning head portion includes an organic substance cleaning unit, an inorganic substance cleaning unit, a rinsing unit and a drying unit. The organic substance cleaning unit, inorganic substance cleaning unit and rinsing unit selectively clean pattern forming regions on a substrate by feeding thereto a first cleaning fluid, second cleaning fluid and pure water, respectively. The drying unit dries the rinsed pattern forming regions by blowing hot air thereonto. The fluid-feeding head portion selectively feeds a liquid pattern forming material to the cleaned pattern forming regions.

A liner for a patch used for covering the surface of a base agent layer of the patch is provided. In the liner of the invention, a tear line portion for dividing and peeling the liner off the base agent layer is provided at a predetermined location, and the thickness of the tear line portion is made thinner than a generally average thickness of the liner. Therefore, when the patch is about to be used, the liner can easily be torn at the tear line portion and peeled off the base agent layer.

A method and apparatus for solid bonding without using a bonding agent are provided. A surface of metal, glass, or other bond members 16a and 16b is fluorinated by exposure to a mixture of HF gas from a HF gas supply unit 24 and water vapor from a vapor generator 26 in a fluorination process section 12. The bond members 16a and 16b are then placed in contact at the fluorinated surface on table 36 in bonding process section 14. Argon is then introduced to bonding chamber 34. Pressure is then applied to the first bond member 16a and second bond member 16b by a cylinder 46, and heated to below the melting point by a heater 48, to bond the first and second bond members together.

A disk cache is controlled to continue duel data writing even during a degenerated mode of operation due to a failure of a cache memory, and also to continue a FAST WRITE process while maintaining reliability for thereby avoiding a drop in performance. If a memory module MM#1 fails, processing of dirty data 111 stored in the memory module MM#1 is continued using backup data 122 stored in a memory module MM#2 for the dirty data 111 stored in the memory module MM#1. The backup data 122 stored in the memory module MM#2 for the dirty data 111 stored in the memory module MM#1 is copied to a memory module MM#3, generating backup data 111' for the dirty data 111. Then, dirty data 131 stored in the memory module MM#3 is copied to the memory module MM#2, generating backup data 112' for the dirty data 131 stored in the memory module MM#3, instead of backup data 112 stored in the memory module MM#1.
摘要:
In a surface treatment apparatus (30) of the face type, a porous dielectric (37) is supported by the outer periphery portion of the supporting member (45) under the bottom surface of a porous electrode (32). The dielectric can be supported by the supporting member to permit the thermal expansion deformation of the dielectric by forming an upward inclined-face (47) and a downward inclined-face (43) on the supporting member (45) and the dielectric (37), respectively. Further, a discharge gas can be supplied uniformly to a discharge region (51) through the electrode (32) and the dielectric (37), both of which are porous. Many gas exhaust ports (41), by which the flow rate of the gas can be regulated, are provided around the discharge region (51). Thus, the gas is uniformly exhausted around the discharge region (51). Especially, if the gap between the dielectric (37) and a work (39) depends on mounting accuracy or the like and varies with location, the gas can be exhausted uniformly around the discharge region (51).

L-aspartic acid is produced by repeating the following respective steps: (1) a reaction step of producing ammonium L-aspartate from an aqueous solution containing monoammonium maleate in accordance with an isomerization reaction and an enzyme reaction caused by aspartase in the presence of ammonia; (2) an ammonia-eliminating step of converting substantially all produced ammonium L-aspartate into monoammonium salt by distilling or stripping a reaction solution obtained in the step (1); (3) a crystallization step of crystallizing L-aspartic acid and producing monoammonium maleate from a solution obtained in the step (2) by adding maleic acid, maleic anhydride or both; (4) a solid-liquid separation step of separating L-aspartic acid crystals precipitated in the step (3) from a mother liquor containing monoammonium maleate; and (5) a recycle step of supplying the mother liquor containing monoammonium maleate obtained in the step (4) to the step (1) to be used as a raw material for the reaction.
摘要:
Magnetic tape pre-read method for using the buffer for pre-read efficiently is provided. This method is executed in a pre-read control unit provided with a buffer margin memory portion and a counter. In this method, the size of data block read from a magnetic tape and the contents of the buffer margin memory portion is compared. When the size of the data block is larger than the contents of the buffer margin memory portion, the counter is incremented. If the count of the counter reaches a predetermined value as a result of the increment, the maximum value of the seize of the data blocks read out in the past is set in the buffer margin memory portion. The count of the counter does not reach the predetermined value unless large blocks appear successively. Therefore, even if large data blocks appear sporadically, the contents of the buffer margin memory portion is maintained.
