Title: Phosphating method
Inventor: OTA TOSHIYUKI
IPC: C25D11/36
Filed: 1988-12-05
Abstract: PURPOSE:To form a phosphate coating film having firm adhesion and superior corrosion resistance on the surface of a metal by carrying out cathodic electrolysis with a phosphating soln. having a specified weight ratio of phosphate ions to all of anions. CONSTITUTION:The weight ratio (P/An) of phosphate ions (P) to all of anions (An) in a phosphating soln. contg. phosphate ions, other active anions and film forming metal ions is regulated to 0.6-0.08. A metal is immersed in the phosphating soln. and subjected to cathodic electrolysis at a low temp. Since the phosphating soln. is rich in the active anions, the metal is considerably etched even at the low temp. By the cathodic electrolysis, only the etched surface is made alkaline, the film forming metal ions in the phosphating soln. are firmly electrodeposited on the surface and simultaneously a phosphate coating film is firmly deposited.

Abstract: PROBLEM TO BE SOLVED: To provide an optical thin film excellent in spectral characteristics and environmental resistance by forming a protective film comprising an oxide on a metal fluoride-contg. film. SOLUTION: A metal fluoride-contg. film 13 is formed on a base body 11. As the base body 11, for example, a CaF2 substrate or a quartz glass substrate is used.

When the metal fluoride-contg. film 13 is a reflection film for light in a UV region, especially for ArF laser light (193.4 nm wavelength), SiO2 having >=70 % transmittance in 1 mm optical length for the light in the above wavelength region is used as the material for the protective film 15. SiO2 is deposited by vapor deposition on the metal fluoride- contg. film 13 to form a protective film 15 (process B). Then the metal fluoride- contg. film 13 on which the protective film 15 is formed is subjected to heat treatment (process C).

Title: Interruption control device for multiprocessor system and its interruption communication method
Inventor: SHIGA MINORU
IPC: G06F13/24
Filed: 1990-11-14
Abstract: PURPOSE:To rapidly receive an interruption by allowing an interruption priority deciding means to previously decide whether a processor itself receives an interruption request or not based upon the execution levels of respective processors stored in an execution level register at the time of generating the interruption. CONSTITUTION:In a processor module interruption control device 200, the interruption priority deciding means 200-6 previously decides whether the processor 100 itself is to receive an interruption or not based upon the execution levels of respective processors stored in the execution level register 200-5 at the time of generating an interruption. At the time of receiving the interruption, an interruption level comparing means compares an interruption level with the least significant execution level (LSEL) of each processor detected by the means 200-6, and only when the interruption level is higher, the LSEL of the processor 100 for receiving the interruption request stored in the register 200-5 is updated to the interruption level.

Abstract: PROBLEM TO BE SOLVED: To obtain a phenol novolak resin compsn. which has a narrow mol.wt. distribution, a low melt viscosity, and a low ortho ratio and is suitable for a curative for an epoxy resin by incorporating a specified amt. or higher of a specific trinuclear compd. into the same. SOLUTION: This compsn. contains 50wt.% or higher trinuclear compd. represented by formula I (wherein R<1> is a 1-10C alkyl; and R<2> and R<3> are each H, a 1-10C alkyl, or a halogen) and has an ortho ratio of 42% or lower. When used as a curative for an epoxy resin, the compsn. enables, because of its low viscosity, the increase in the amt. of an inorg. filler compounded and gives a cured material having a low water absorption and a good moisture resistance. The trinuclear compd. is produced by reacting 1mol of an ortho-substd. phenol represented by formula II with about 1.8-2.2mol of formaldehyde under an alkaline condition, condensing the resultant resole with the phenol represented by formula II under an acidic condition, and removing water and the unreacted phenol from the resulting product.

Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To utilize residual soil by constructing bank bodies with a slurry and highly viscous fluidization treated soil comprising mainly residual soil and back filling a slurry and low viscous fluidization treated soil comprising mainly residual soil between the bank bodies. SOLUTION: A burying ditch 1 is excavated, and a buried matter 3 such as Hume pipe is laid down on a laid sand 2 formed at the bottom part of the burying ditch 1. Next a slurry and highly viscous fluidization treated soil comprising mainly residual soil is sprayed or deposited by a mold work method in the excavation advancing direction of the burying ditch 1 so as to construct a bank body 4. Also a slurry and low viscous fluidization treated soil as backfilling material 5 comprising residual soil is back filled in the burying ditch 1 divided by the bank bodies 4 and 4a. In this case, a buoyancy F generated on the buried matter 3 is cancelled by the self gravities W and W of the bank bodies 4 and 4a so as to stop their rise. The same procedure is repeated so as to bury the buried matter. Thus residual soil for construction can be utilized effectively.

Title: Fixing device
Inventor: ADACHI TAKEFUMI
IPC: G03G15/20
Filed: 1992-11-18
Abstract: PURPOSE:To obtain a fixing device provided with a bearing having high load resistance and requiring small space by using a needle bearing for at least one pair of bearings holding a heat roller and a pressure roller. CONSTITUTION:The heat roller 21 is received by a heat roller bearing 28, which is the needle bearing, and held by a frame 30. In the case load imposed on the heat roller 21 is equivalent, the needle bearing has higher pressure resistance than a ball bearing, so that the bearing diameter phiD is made smaller by adopting the needle bearing. In the case thrust load imposed on the bearing 28 is comparatively small, such a needle type bearing can be used enough. The needle bearing is constituted of an inner ring 28a, a needle 28b and a metallic outer ring 28c. Since the inner ring 28a facing to the heat roller 21 is made of heat insulating resin such as polyphenylene salfite, for example, a heat insulating bush need not to be interposed.

Title: Replacement algorithm and computer system using the same

IPC: G06F12/08
Filed: 1990-11-16
Abstract: PURPOSE:To accelerate communication between CPUs by defining a data having old reference or registration as the object of replacement when the degree of importance is much lower or equal. CONSTITUTION:In a storage controller (SC) 3, a communication buffer storage device (CBS) 14 is provided to copy only the data to be exchanged between CPUs 1 and 2 from a main storage device (MS) 4 and to store the data, and a CBS replacement array (CBRA) 13 is provided to store an index for selecting a block to be the object when replacing the registration unit of this data. In a system having only one kind of instructions, it is judged for the block referred to by the specified instruction that the data standard is high, and it is judged for the other that the data standard is low. When the number of times for referring to the same block within the fixed period exceeds the regulated number of times, the data standard is increased and when it is lower than the regulated number of times, the data standard is lowered. Thus, since CPUs 0 and 1 exchange the data through the CBS, communication between the CPUs 0 and 1 can be accelerated and therefore, the processing can be accelerated.
