Abstract: A method of manufacture of a glass substrate for a magnetic recording medium, which has both high substrate strength and low alkaline elution, includes an etching process of etching the inner-edge face of a donut-shaped glass substrate having an aluminosilicate composition, formed by removing the center portion of a die-molded disc-shaped glass substrate, and an alkali sealing process of performing alkali sealing treatment by proton substitution of alkali ions in the surface layer of the etched donut-shaped glass substrate. The process is used to manufacture a magnetic recording medium incorporating a glass substrate having a total alkaline elution amount of less than 3.1 ?g/disk, wherein the magnetic recording medium has a transverse rupture strength greater than 132 N.

Abstract: Information recording medium glass substrate which is a molded article composed of an alkali metal-containing glass material having a composition including at least B, Al, alkali metals, Zn, and Si, and satisfying certain relational equations in molar proportions in terms of oxides thereof, has a low molding temperature, excellent durability, and a reduced number of surface defects. An information recording medium having such a glass substrate and a magnetic layer formed thereon has excellent low-temperature workability and excellent weathering resistance. The glass substrate is suitable for perpendicular magnetic recording because the glass composition suppresses alkali elution from the glass substrate and the glass substrate has substantially no surface-attached foreign matter having a height of about 10 nm or less and having SiO2 as a main component thereof.

Abstract: The invention relates to an earth pressure system shield process. First of all, an excavation additive consisting of the mixture of an agent for improving fluidity and viscosity of an excavated soil and a mud improving main agent is added (Ic, P.sub.2) to the excavated soil at the time of shield excavation at the working face, inside a mixing chamber (1b) of a shield machine (1) and inside a soil discharge screw conveyor (3) to sufficiently mix the excavated soil with the improving main agent and a mud improving assistant agent is then added (5) inside the soil discharge screw conveyor (3), so that the seal covered by the improving main agent so as not to be disssolved in water is removed chemically by this assistant agent. In this manner, the excavated soil is improved to a high quality soil having low fluidity inside the soil discharge screw conveyor (3) and is discharged.
