Abstract: PURPOSE: To correct various aberrations at high degree even when focusing at close distance, by combining two groups of lenses of specified constitution.  
     CONSTITUTION: A first lens group is constituted with, from the object side sequentially, a convex lens, a concave lens, and lens A of which distance from the object side face of the first convex lens is l 1 , l 2 ...lN≤l, with refration power ϕA, lens A containing the divergence face directed in one side towards the object side having refraction power of ϕB at curvature radius RB. A second lens group consists of lenses of negative refraction power containing the divergence face having the convex side directed towards the object side. F is the focal ength of the entire lens system. The lens groups are constituted so as to satisfy the conditions of 0.38F>lN...>l 2 >l 1 >0.15F, 1.2>ϕA.F>-1.0, 0.15F>RB>0.06F, 12.5> 1ϕB1.F>0.5.As a result, the incident height of the ray above the axis entering the lens divergence face having the convex side directed to the object side in lens A may be higher, and the occurrence of spherical aberration in the positive direction on this face increases and the spherical aberration increasing in the negative direction may be canceled.

Title: Substrate for information recording medium and its production
Inventor: NAGANO KAZUMI
IPC: G11B7/24047
Filed: 1989-04-27
Abstract: PURPOSE:To obtain the substrate for the recording medium which has excellent solvent resistance and obviates the degradation in recording sensitivity by forming the specular surface on the rear side of the resin substrate provided with rugged preformats on the front side to the degree of crosslinking higher than the degree of crosslinking on the preformat forming surface on the front side. CONSTITUTION:The substrate 1 has the surface 6 grooved with the rugged preformat patterns and the specular surface 7 on the rear side is formed of a transparent resin having the degree of crosslinking higher than the degree of crosslinking of the grooved surface 6 on the front side. The production of this substrate 1 is executed by providing a crosslinking agent layer 10 on a specular surface mold 9, then installing this layer onto a cast molding device 8, injecting the liquid transparent resin into the mold and solidifying the resin. Since the rear surface is provided with excellent chemical stability and high hardness in this way, the generation of roughening and cracking of the coated surface by the solvent used for forming the hard coat layer 5 by coating is prevented. The surface in contact with the recording layer 2 is low in the degree of crosslinking and the substrate surface does not suppress the deformation when the pits of the layer 2 are deformed at the time of recording. The degradation in the recording sensitivity is obviated.

Abstract: PURPOSE:To make the reduction of the temperature drop of cast bloom due to increase of temporary stock amount of cast bloom accompaying the increase of hot bloom amount possible, by a method wherein cast blooms are manufactured by arranging a part of the manufacturing period to lap with another one when cast blooms from plural cast bloom manufacturing units are continuously charged into a specified reheating furnace as hot one. CONSTITUTION:Periods for manufacturing cast bloom of continuous casters A and B are lapped and, for example, blooms are charged into a reheating furnace in sequence of casting unit and rolled so that temporary stock of lapped part may be disposed within the same casting unit. By designating a casting time of one casting unit of caster A (hereinafter) referred to as CC cycle) to be T and by designating the lap time between this cycle and the previous CC cycle of caster B to be L, the lap ratio R is defined as given by a formula. When R=0%, the immediate charge of cast bloom to reheating furnace and the unit power consumption is very high. When R is raised, line efficiency is increased, unit power consumption being decreased, fuel consumption being deteriorated according to the increase of temporary stock amount at the other side and its affect is decreased by reducing CC cycle amount (multiple conti-continuous casting amount). From these connelations, the optimum conditions are selected.

Abstract: Polyamines containing from 0.19 to 20.3 wt % primary amino groups are produced by hydrolyzing in a single stage an isocyanate with an excess of water, a relatively weak basic compound and a water-miscible polar solvent at a temperature from 50 DEG  to 165 DEG C. The hydrolysis is conducted in a manner such that the reactants are substantially homogeneous during the reaction. The isocyanate should have an NCO-content of from 0.5 to 40 wt %. The weakly basic compound may be a carbonate or hydrogen carbonate of an alkali metal or an alkali or alkaline earth salt of a monocarboxylic or polycarboxylic acid or mixtures of such materials. The polyamines produced by this process are particularly useful in the production of polyurethanes.
