Abstract: PURPOSE:To improve the sensitivity to light of a near IR region such as semiconductor laser light by dispersing a light absorptive material which absorbs near IR light into an optical recording material to form an optical recording layer. CONSTITUTION:The optical recording layer 4 formed by dispersing the light absorptive material 3 having the compsn. consisting of xAs2Se3-yAs2Te3 into the optical recording material 2 consisting of As2Se3 is formed on a substrate 1 consisting of quartz glass.

IPC: H04L69/14
Filed: 1995-06-29
Abstract: PURPOSE: To provide an access controller which reduce communication delay without the need to time the start of communication. CONSTITUTION: A no-signal time measurement part 1a measures the continuance of a no-signal state on a communication line Ca and sends the measured value to a transmission control part 1d.

Title: Method for heat-treating boron-added silicon wafer
Inventor: AKATSUKA MASANORI
IPC: H01L21/20
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To heat-treat a boron-added silicon wafer without causing any slipping dislocation by empirically finding in advance the dislocation anchoring force caused by boron and easily and surely grasping the optimum temperature dropping/raising rate without conducting any experimental heat treatment by calculating the rate from relational expressions. SOLUTION: The temperature difference ΔT which occurs in the surface of a semiconductor wafer when the wafer is heat-treated is expressed by formula I, where, R, ρ, and d respectively represent the temperature raising/dropping rate, specific heat, wafer diameter and T, σ, w, and (t) respectively represent the temperature, Stefan- Boltzmann constant, wafer interval, and wafer thickness. The decompositional shearing stress S of thermal stress when the temperature difference T occurs in the surface of the wafer is expressed by formula II and exceeds the anchoring force τ caused by boron. From formulae II and III, formula IV about the temperature raising/dropping speed is derived. In formula IV, α, E, (r), and respectively represent the coefficient of linear expansion, Young's modulus, wafer radius, and dislocation anchoring force caused by boron.  When formula V is derived by substituting formulae I and II for formulae IV and the τ is empirically found, the critical temperature raising/dropping speed can be derived from formula III.

Abstract: PURPOSE:To prevent generation of a surface flaw like crazing to the surface of a continuous casting billet in the stage of casting continuously a steel contg. elements which are liable to produce carbonitride by applying work strain to the continuous casting billet at the point of the time when the surface of said billet is cooled down to a specified temp. and increasing further the surface temp. by the heat regenerated from the internal unsolidified molten steel part. CONSTITUTION:The continuous casting billet emerged from a continuous casting mold is once cooled until the surface temp. of the continuous casting billet decreases down to <1,000 deg.C in the stage of casting continuously an Al-killed steel or a molten steel contg. elements such as Nb, Ti, B or the like for improving strength and toughness of the continuous casting billet. The billet is subjected to impact working such as shot peening, air hammering or the like at the point of this time to apply work strain to the surface thereby forming the nucleus for carbonitride precipitation. The surface temp. is increased again to >=1,000 deg.C by the heat regenerated from the unsolidified molten metal in the continuous casting billet and is held for at least 5min to decrease the number of the precipitation of the carbonitride and to agglomerate and coarsen the carbonitride so that the straightening point is passed. The ductility of the continuous casting billet is considerably improved and the generation of the surface flow like crazing is suppressed.

Title: Wire rope torsion eliminating method and working jig for it
Inventor: IZUMIKAWA SHINICHI
IPC: B66C13/00
Filed: 1995-06-30
Abstract: PURPOSE: To easily and safely eliminate unavoidable torsion generated on a wire rope of an overhead crane. CONSTITUTION: After a takeup drum 7 is fixed, a rope end 1c is connected and supported to a handrail 2a on a crane crab side through a connecting member 11 so connected as not to be relatively rotated and a wire rope supporting member 12 connected to the connecting member 11 so as to be freely rotated. After fixing of the rope end 1c to the drum 7 by a fixing tool 6 is released, the connecting member 11 is rotated in the torsion eliminating direction of the rope 1 by an operating spanner 14 by the specified amount in a state where the rotation in the torsion direction of the rope 1 is stopped by a supporting spanner 13. After the rope end 1c is fixed to the drum 7 by the fixing tool 6, a jig 10 of the connecting member 11 is removed.  When the drum 7 is rotated, the torsion of the wire rope 1 is eliminated by being canceled by the torsion in the torsion eliminating direction applied to the wire rope 1 by the rotation of the connecting member 11.
