Abstract: PURPOSE:To convert unstable harmful heavy metal salts into a stable state and to separate and recover alkali metal salts, by adding an iron salt and alkaline substance to the aqueous slurry of pulverized waste matter containing heavy metals, separating it by filtration, and then heating the formed residues. CONSTITUTION:Waste matter A such as dust is charged in a water tank B and changed into suspension, so as to dissolve water-soluble alkali metal salts and heavy metal salts in water. Iron salt C and alkali D are then added to convert the heavy metal salts into water-insoluble hydroxides with the added iron salt. Thereafter, the suspension is precipitated and filtered by a filtering device E. The alkali metal salts transfer to the side of a filtrate F, while the heavy metal hydroxides, etc. remain at the side of filtering leftovers G. The mixture 3 of the hevy metal hydroxides, ferric hydroxide, etc. at the side of filtering leftovers G is converted into residues 4 stable even to acidic water by heating it at a predetermined temperature in a heat-treating device 1.

IPC: G06F15/16
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To improve the reliability against a memory fault by constructing a memory subsystem which has an error correcting function by using hardware. SOLUTION: A redundant code memory 16 and a BIB/CM controller 15 which controls it are provided, and when the execution of data writing to a main memory 14 is detected by monitoring a bus transaction issued on a bus 10, a redundant code corresponding to the data is automatically generated in the controller 15 from the value of the data on the bus 10 and stored in a corresponding storage area of the redundant code memory 16.

Title: Information recording medium
Inventor: KOBAYASHI TADASHI
IPC: G11B7/24062
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To secure a sufficient tilt margin and mechanical strength even if a recording density is increased by setting the distance from the recording surface to the surface to be irradiated of a substrate smaller than the thickness of the substrate, and forming the bonding and adhering surface of the substrate to a smooth surface or a surface having recessed parts. SOLUTION: Embossing pits 2 corresponding to recording data are formed on the surface of the substrate 1 and the reflection film 3 is deposited on this recording surface. Further, the surface thereof is over-coated with a protective film 4. The reading of the recorded data is executed by condensing a light beam 5 with an objective lens 6, making the condensed beam incident on the recording medium from the protective film 4 side and detecting the light intensity change of the reflected light from the reflection film 3 as the recording data of the embossing pits. The distance from the embossing (recording surface) to the surface (surface to be irradiated) on the protective film 4 side is regulated to the distance smaller than the thickness of the substrate 1 and, therefore, the film thickness of the protective film is smaller than the substrate thickness.  Then, the recording medium is hardly restricted in the tilt margin by the substrate thickness and a higher density recording is made easy.

Abstract: PURPOSE:To properly correct density irregularity even when density irregularity is not accurately corrected by detecting the density distribution of a pattern to form the correction data of a driving condition for uniformizing density at the time of image formation and forming the test pattern so as to make the same larger than the region subjected to the formation of the correction data. CONSTITUTION:Density correcting data is formed in a step S27 and signals are sampled in the number corresponding to the number of emitting orifices from density irregularity reading signals to be set to the data corresponding to the respective emitting orifices. When these data are set to R1, R2,...RN (N: number of emitting orifices), these data are subjected to operation becoming Cn=-log(Rn/RO) (wherein RO is a constant becoming RO>=Rn and n is 1<=n<=N) to be converted to density signals. Next, mean density C'=SIGMANCn/N is calculated by operation. Continuously, the shift degrees of the densities corresponding to the respective emitting orifices with respect to the mean density are operated according to DELTACn=C'/Cn. Next, the signal correction quantity (DELTAS)n corresponding to (DELTAC)n is calculated according to DELTASn=AXDELTACn (wherein A is the coefficient determined by the gradation characteristic of a head). Succeedingly, the selection signal of a correction straight line to be selected corresponding to DELTASn (step S27) and irregularity correcting signals are stored in a backup RAM in the number corresponding to the number of the emitting orifices in a step S29. The correction straight line is sleeted at every emitting orifice on the basis of each of said irregularity correction data to correct density irregularity.

IPC: G03F1/00
Filed: 1992-05-19
Abstract: PURPOSE:To make fluidities of resists at the time of spin coating with the resists for all unit patterns uniform and to form thicknesses of resists all the same by forming patterns of the unit including electrodes in rotationally symmetric with respect to the center of a wafer. CONSTITUTION:Unit patterns including electrodes are so arranged rotationally symmetric with respect to the center of a wafer. Thus, angles formed between the sides of the electrodes and a radial line become equal for all unit patterns of a circumferential direction. Accordingly, when the resists are spin coated, fluidities of the resists become equal for all unit patterns of a circumferential direction. As a result, thicknesses of the resists become constant, and an irregularity in sizes of the patterns is reduced when gate electrodes and wiring patterns are formed later. Thus, devices having uniform electric characteristics can be manufactured.
