Abstract: An automated analyzer includes: a measurement device; at least one sample tray on which a plurality of sample containers is placed; a conveyance device configured to select one of the plurality of sample containers placed on the sample tray, convey the selected sample container to the measurement device, and return the sample container to an original sample tray on which the sample container was originally placed after measurement by the measurement device; a control device for controlling an operation of the conveyance device; and a retreat portion provided at a position different from positions where the measurement device and the sample tray are provided, the retreat portion being configured to temporarily place the sample container. The control device causes the sample container to retreat to the retreat portion in a case where the sample container cannot be returned from the measurement device to the sample tray.

Abstract: Before start of analysis, a user inputs pipe capacity difference relative to reference pipe capacity and separation conditions, such as a mobile phase flow rate. A control unit calculates retention time shift from the pipe capacity difference and the flow rate. The control unit controls sample injection and data processing units so as to start collection of chromatogram data when a correction time has passed from the time point of sample injection in the case in which the value of the retention time shift is a positive value, and to perform sample injection when a correction time has passed from the time point at which the collection of chromatogram data is started in the case in which the value of the retention time shift is a negative value. Retention time shift caused by difference in the pipe capacity is corrected even when the mobile phase flow rate is different.

Abstract: A process for producing a biocompatible implant material which can be suitably shaped into a variety of forms. A binder is added to a mixture of hydroxylapatite powder and calcium phosphate glass frit (5 wt. %), to thereby prepare a slurry, and the resultant slurry is granulated, to prepare spherical raw material granules. Separately, spherical polyisobutyl methacrylate particles are prepared, and the particles are dry-mixed with the above-prepared granules, to thereby obtain a powder mixture. The powder mixture is compacted using a mold press, to thereby form a cuboid sample. The resultant compact is heated in a drier at 170° C. for three hours, to thereby melt spherical polyisobutyl methacrylate particles. Thereafter, the compact is allowed to cool, to thereby bind the raw material granules together via the polyisobutyl methacrylate that solidifies after melting. After the compact is allowed to cool, the compact is subjected to shaping by use of a copy machining machine and also to drilling.

Abstract: The present invention provides a method for producing a calcium phosphate coating film on the surface of a substrate, even a substrate which has poor heat resistance. The method comprises the steps of soaking a substrate in a first solution containing phosphate ions, inter alia, aqueous solutions of a basic phosphate salt such as Na.sub.3 PO.sub.4 or Na.sub.2 HPO.sub.4 ; removing the substrate and drying it; and soaking the substrate in a second solution (aqueous solution) containing calcium ions, to thereby obtain a coating film comprising hydroxyapatite or a mixture containing hydroxyapatite and a hydroxyapatite precursor. The substrate removed from the second solution may be soaked in a third solution (aqueous solution) containing an apatite component at a substantially saturated or supersaturated concentration, to thereby form a hydroxyapatite coating film. There may be used substrates formed of metals, ceramics, organic polymer materials, etc.

Abstract: An internal liquid for a reference electrode containing lithium chloride (LiCl) and ammonium nitrate (NH.sub.4 NO.sub.3) in a dissolved state at a ratio [NH.sub.4 NO.sub.3 ]/[LiCl].gtoreq. 4. Internal liquid also contains AgCl to saturation for use with an Ag--AgCl internal electrode, and is in a gellated state or impregnated in a highly water-absorbent synthetic resin. It is used in conjunction with a comparison electrode or an internal reference electrode for an ion-selective electrode.Drying up of the internal liquid in the gellated state is minimized so that the function of the internal liquid as a liquid bridge may be displayed for a prolonged period of time. If the ionic concentration of the liquid under examination is changed, liquid potential difference remains substantially unchanged to provide a stable reference electrical potential.
