Abstract: This invention relates to a process for producing a quality-improved water-absorbent polymer in which the aqueous liquid ( I ), which is obtained by mixing in an aqueous medium at least one kind of a water-soluble salt ( A ) selected from a group of halogenated compounds, sulfates, acetates, and nitrates, which are derived from at least one kind of a polyvalent metal selected from a group of aluminum, calcium, and magnesium, with at least one kind of a water-soluble salt ( B ) selected from a group of monovalent metal salts and ammonium salts, which are derived from at least one kind of an oxyacid selected from a group of sulfurous acid and thiosulfuric acid, is mixed with a water-absorbent polymer ( II ) in a proportion of that the water-soluble salt of the polyvalent metal ( A ) is in a range of 0.1 ∼ 10 parts by weight against 100 parts by weight of the water-absorbent polymer ( II ) and the water-soluble salt of the oxyacid ( B ) is in a range of 0.­1 ∼ 10 parts by weight against 100 parts by weight of the water-absorbent polymer ( II ). The mixture which is obtained by mixing the aqueous liquid ( I ) with the water-­absorbent polymer ( II ) has relatively-improved capacities   in the fluidity and the amount of residual monomers. This invention displays a more sufficient effect by compulsorily bringing the mixture into contact with an oxygen-containing gas.

Abstract: A system suitable for use on a computer network provides a user interface (10) on a local node and an application (34) to be run on a remote node. An application (14,30) for accepting input from the user and translating it to appropriate commands for the remote application is divided, and located partially on the local node and partially on the remote node. That portion located on the local node (14) gathers any information required from the user and transmits it to the portion located on the remote node (30) in a single package. The remote location portion uses the transmitted information to interface with the remote application and obtain results. The results are collected and transmitted to the local portion, from which they are returned to the user.

Abstract: When linearizing FMCW radars it is customary to produce a synthetic target signal independently of the radar signal and to use the synthetic target signal to linearize the sweeping of the transmitted VCO frequency or the sampling of the radar if signal to be analysed. In order to reduce the overall number of microwave rf components, the present invention uses one mixer (18) to produce the radar if and linearizing if. In one embodiment an rf STALO (32) is coupled by a directional coupler (34) into the return path of the radar signal. In other embodiments (not shown) the mixer comprises a dc biased waveguide harmonic mixer and the STALO generates a lower frequency which is applied to the mixer by way of either the bias port or the radar if output port. The linearizing arrangements (28) disclosed are based on known designs.

Abstract: A method of controlling a stepping motor for supplying a drive current to each of the phase windings (5a, 5b) thereof in response to control signals. The control signals are formed by combining logically phase exciting signals (c, d, e, f) and overdrive signals (b₁, b₂) in synchronism with a clock pulse signal (a). Each of the overdrive signals includes a pulse with a longer width (t w1 ) at an earlier stage of a phase exciting duration during which a drive current flows in the stepping motor, and a pulse with a shorter width (t w2 ) at a later stage of the phase exciting duration. hence, a smaller drive current flows in the phase windings (5a, 5b) during a later stage of the exciting duration, reducing power consumption.

Abstract: The data processing system translates a logical address made up of a partial space number, a logical space number and an address within a page to a physical address made up of a physical page number and the address within a page and accesses a memory section under the coexistence of a plurality of page sizes. The system further comprises a table holding section for holding a plurality of sets of copies of a plurality of address translation tables stored in the memory section on a partial space basis. The plurality of sets of copies are each assigned to a particular page size. A load control section loads one of the plurality of address translation tables into the table holding section in response to an address translation table load command. A directory supervising section supervises partial spaces each corresponding to one of the plurality of address translation tables held in the table holding section. A first loading section executes by defining the partial spaces assigned to the same page size as a single supervisory unit in the directory supervising section, load control over the plurality of address translation tables independently. This data processing system is capable of translating addresses having a plurality of page sizes dynamically to thereby enhance efficient use of a memory and improve the overhead of an operating system.
