摘要:
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. Thereafter, the compact is heated at a rate of 300° C. hour, and fired at 1,250° C. for three hours, to thereby produce a biocompatible implant material.
摘要:
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. The method is applicable to a substrate having poor heat resistance, such as synthetic resin fabric, due to omission of high-temperature treatment.

A parameter display part including a single upper-hierarchical parameter screen displaying only a selected parameter and a number of lower-hierarchical parameter screens corresponding to respective units displaying all parameters for the respective units, and providing switchable display capability. When selecting a parameter to be displayed on the upper-hierarchical parameter screen, moving the cursor to the parameter on any of the lower-hierarchical parameter screens and pressing the function key to select a display, the selected parameter is displayed on the upper-hierarchical parameter screen. When the parameter is selected again, the function key is pressed, and the display on the upper-hierarchical parameter screen is canceled.

摘要:
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.
