Abstract: A method for measuring trace quantities of OH groups in quartz glass comprises preparing a set of test pieces comprising a reference test piece from a blank of a quartz glass body whose OH group content is known and a sample test piece from a quartz glass body whose OH group content is to be measured, having two planar planes faced to each other, setting the sample test piece and the reference test piece in an infrared spectrophotometer; successively irradiating perpendicular to one of the two planar planes an incident infrared radiation in a wavelength region of approximately 2500 nm to approximately 2950 nm, while simultaneously detecting the outgoing radiation spectrum from the other plane; obtaining the difference of the outgoing radiation spectrum of each of the test pieces; selecting the absorbance peak assigned to OH groups at a wavelength of 2720 nm to obtain the peak height thereof; and calculating the concentration of OH groups from the peak height in the sample test piece.

Abstract: A reproducing magnetic field correcting unit is provided, a reproducing state is monitored while increasing a reproducing magnetic field by using a predetermined reproducing magnetic field as an initial value H1, and a reproducing magnetic field when a reproducible state is obtained is determined as an optimum magnetic field. A reproducing magnetic field obtained by adding a predetermined value to the reproducing magnetic field in the reproducible state is used as an optimum reproducing magnetic field. A change in reproducing magnetic field is started from the low magnetic field in which a predetermined value is subtracted from the initial value. A shoulder portion is certainly detected and the optimum magnetic field is set.

Abstract: There is provided an optical storage device that can position a lens carriage and objective lens even when position sensors for the lens carriage and objective lens are excluded in an effort to make an optical disk unit thinner. When a seek of the carriage relative to an optical disk is started, the carriage is accelerated smoothly, decelerated smoothly, and thus positioned on a target track. The vibration of a lens actuator on the carriage occurring during seek can be minimized, and the lens actuator is locked substantially in the center of the carriage. During a seek operation of the carriage, a false lens signal equivalent to a lens signal used to lock the lens actuator in the center of the carriage is produced using the envelope of a tracking error signal obtained from reflected light of the light beam emanating from the optical disk. With the false lens signal, the lens actuator is locked in the center of the carriage.

Abstract: A low speed lens lock control unit detects an amount of an optical axial deviation of an objective lens from an offset of a tracking error signal which is obtained in a low speed seeking mode and drives a carriage actuator so as to set the optical axial deviation of the objective lens to zero. A high speed lens lock control unit detects an amount of an optical axial deviation of the objective lens from an offset of a tracking error signal which is obtained in a high speed seeking mode and drives a lens actuator so as to set the optical axial deviation of the objective lens to zero.

Abstract: The present specification discloses a ruminant feed additive composition which contains as an active ingredient a phosphoric acid-amino acid-polyvalent metal composite salt (final composite salt) which is insoluble in neutral or alkaline water and is soluble in acidic water and which can be obtained by treating a composite salt composed of a basic amino acid, magnesium and phosphoric acid with a salt of a divalent or trivalent (polyvalent) metal other than magnesium, or by treating the above-mentioned composite salt with the polyvalent metal salt and a condensed phosphoric acid component (alone) or the condensed phosphoric acid component and a phosphoric acid component (in combination), this composition taking the form of a powder or granules. The above-mentioned final composite salt can exhibit the excellent stability to neutral or slightly acidic water, namely, the low solubility therein in comparison with the intermediate composite salt, and it can have both the excellent insolubility of the basic amino acid in a rumen of a ruminant and the excellent elution thereof in an abomasum and lower digestive organs.
