Title: Production of nonaging high strength cold rolled steel plate of superior painting baking hardenability
Inventor: TAKAHASHI NOBUYUKI
IPC: C21D9/46
Filed: 1980-10-04
Abstract: PURPOSE:To produce a nonaging high strength cold-rolled steel plate of superior painting baking hardenability inexpensively by conbining a component system consisting mainly of addition of P, high cold drafts and continuous annealing by low- temp. soaking. CONSTITUTION:The steel of 0.02-0.12 C by wt%, <=1.0 Si, 0.10-1,2 Mn, 0.025- 0.15 P, 0.010-0.10 acid-soluble Al, and the balance Fe and unavoidable impurities is melted to make a slab. This is hot-rolled, and is coiled to below 550 deg.C. After descaling, it is cold-rolled at >=65% draft. Following this, it is soaking for max. 3min at above its recrystallization temp. and below 720 deg.C, after which it is quickly cooled at >=5 deg.C/sec, whereby a steel plate is obtained. Here, the amt. of P is required at above the lower limit in order to improve strength and painting baking  hardenability, but in excess of the upper limit, said hardenability, etc. degrade. The  high draft is intended for reduction of the solubility limit of C and the formation of deposition site for carbide and nitride. The lower limit of the annealing temp. is determined from the balance between strength and ductility, and the upper limit from the prevention of the cohesion of AlN and the lumping of carbide, and an excessively long time results in the cohesion of carbonitride.

Filed: 1989-06-02
Abstract: PURPOSE:To shorten time for accessing data by providing one alternative sector at least in each recorded track and replacing a sector, where a defect is generated, with the alternative sector of the same recorded track or the other recorded track close to the recorded track. CONSTITUTION:In each recorded track, the final sector is set to the alternative sector and the defective sector, which is generated in the same recorded track or the closed recorded track, is replaced with the alternative sector.

Filed: 1986-06-16
Abstract: PURPOSE:To remove an interference with etching of a contact hole and the like in a subsequent process, by laying a polycrystalline silicon film beforehand under a boron phosphorus glass layer. CONSTITUTION:A silicon oxide film 6 is formed in such a degree that a resistance value of a source-drain element is not increased and that a polycrystalline silicon gate edge is not raised. Next, polycrystalline silicon 7 is made to grow, by a reduced-pressure chemical vapor deposition method or the like, to have a thickness a little smaller than a half of the thickness of the oxide film whereby the polycrystalline silicon is oxidized, during a time required for implementing a flow processing of a boron phosphorus glass layer by water vapor. Thereafter the boron phosphorus glass layer 8 is formed by deposition. When heat treatment is applied in an atmosphere of water vapor and at a high temperature of 800 deg.C or above, subsequently, the boron phosphorus glass layer 8 of the surface shows fluidity, the polycrystalline silicon turns entirely to be an oxide film, and simultaneously the surface becomes smooth.

Abstract: PURPOSE:To reproduce a voice excellently with a small arithmetic quantity irrelevantly to a bit rate by dividing a frame into subframes corresponding to a pitch period and using multipulses which are found by pitch interpolation and multipulses which are found on the whole frame without pitch prediction. CONSTITUTION:The voice signal from an input terminal 100 is divided into specific frames and an LPC and a pitch analysis part 150 finds an LPC coefficient of specific degree as a spectrum parameter representing a spectrum envelope from the voice signal of a frame. A pitch interpolation multipulse calculator 250 divides the frame into subframes by using a pitch period, finds the amplitude and position of multipulses in one specific section, and finds gain correction coefficients and phase correction coefficients of other subframes. Then a sound source signal is restored by specific arithmetic operation through a subtracter 260 and a multipulse calculation part 270 and then processed by composition. Consequently, the excellent voice can be reproduced with a small arithmetic quantity irrelevantly to the bit rate.
