Title: Method and device for obtaining sat solver architecture with a little overhead of synthesis and layout
Inventor: ASHAR PRANAV
IPC: G06F17/50
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To make solvable a Boolean satisfiability test(SAT) formula by using a Boolean SAT solver composed of plural reconfigurable hardware modules. SOLUTION: The Boolean SAT formula is read and expressed in a regular AND form (S200). The Boolean SAT formula is divided and limited within the number of variables in respective predetermined clauses. Each division of the Boolean SAT formula is divided into regular AND expressions (S210). A clause module is shaped and a compiled clause module is arranged on an entire field programmable gate array(FPGA) (S220). The Boolean SAT formula division is assigned to a circuit array in plural reconfigurable hardware modules (S230). In each circuit array of the hardware module, a function and a connection peculiar for each division of the Boolean SAT formula are programmed (S240).

Title: Magnetic disk device
Inventor: TSUNODA MOTOYASU
IPC: G11B20/10
Filed: 2000-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent decrease in a memory capacity due to defective memory areas by selecting one recording area from residual recording areas subtracted from original plural disk form recording areas by the fixed number of recording areas only for areas of defective tracks or defective sectors. SOLUTION: The magnetic disk device receives m-bit parallel data, and divides them into small data of n-systems of which each consists of m/n (m, n are integers, and n<=m) bit parallel data, and each small data is parallel-serial converted and encoded, and then, written on n-pieces of disk form recording areas in parallel. After these n-pieces of small data are read out, decoded, and serial-parallel converted, they are integrated into m-bit parallel data and outputted. When a defective track or defective sector is detected, a selecting circuit selects one of the plural residual disk form recording areas only for the defective area, a head corresponding to the area is made to write or read the data in the substitution track or a substitution sector.

Title: Silicon compound thin film deposition method, and article obtained by using it
Inventor: TOYOSHIMA TAKAYUKI
IPC: C03C17/22
Filed: 2000-04-03
Abstract: PROBLEM TO BE SOLVED: To solve the problem that an antireflection coating prepared by a vacuum film deposition method is conventionally deposited on a substrate by means of the so-called multilayer structure consisting of a lamination of high- refractive index film and low-refractive index film but the resultant coating is increased in internal strain and liable to cause peeling at the interface between the coating and the substrate and, further, the use of two or more kinds of vapor deposition material is required. SOLUTION: A vapor deposition material of silicon metal is evaporated by arc discharge plasma irradiation in a deposition chamber where reduced- pressure atmosphere is regulated, by which a glass plate is coated with a silicon compound thin film. At this film deposition, a gradient of refractive index is provided in a film-thickness direction by changing the gas ratio between oxygen and nitrogen in reactant gas constituting the reduced-pressure atmosphere in the course of evaporation of silicon metal. By this method, the antireflection coating, capable of reducing the reflectivity of the surface of the glass plate from 4% to 0.5%, can be the deposited in a state of a single- layer structure.
