≪１級課題-化学-≫【問 1】[Claim 1]
A dental implant comprising:a jawbone-embedded section that has compatibility with a jawbone; anda gum-contacting section continuously formed with the jawbone-embedded
section and configured to be inserted into the gum, wherein a gum-contacting region of
the gum-contacting section is coated with a cell adhesive layer containing a polypeptide
or a protein so as not to impede the compatibility of the jawbone-embedded section withrespect to the jawbone.
[Claim 2]
The dental implant according to claim 1, wherein an outer surface of the cell adhesive
layer has an arithmetic mean roughness Ra of 2 micrometers or less.
[Claim 3]
The dental implant according to claim 1 or 2, wherein the outer surface of thejawbone-embedded section for contact with the jawbone is coated with an apatite layer
or is subjected to alkali and heat treatment.

【問 2】[Background of the Invention][0006]
In conventional electric double layer capacitors, since the capacity of the positiveelectrode is small, there is a problem that the capacitance of the capacitor does notincrease even if the capacity of the negative electrode is increased. That is, whenaluminum foil is adopted as a current collector of the positive electrode, if activatedcarbon is thickly applied in order to increase the capacity of the positive electrode, theutilization efficiency decreases or the activated carbon peels off, with the result that thecapacitance cannot be increased. For this reason, the capacity of the positive electrodeis small in relation to that of a carbon-based negative electrode that allows Li ions tomove in and out, and the energy density of the cell cannot be increased.
[0007]
Also, since the electric potential of activated carbon is 3 V (vs Li / Li +), the cellvoltage can only be raised to about 2.5 V in view of the withstand voltage properties ofan electrolytic solution. For this reason, there are problems in that the voltage is low,and the energy density and output power density are low.

【問 3】
For efficient oxidation treatment, it is preferred that, after copper smelting slag ischarged into a slag treatment furnace, a jet of a gas mixture formed of a fuel gas, suchas natural gas and/or propane gas, and oxygen gas be created and blown through alance into the slag. This may be performed by blowing a gas mixture containing excess
oxygen with respect to the gas composition for complete combustion, which allows
oxygen gas at an extremely high temperature to be supplied to the slag. For example,
the combustion gas produced by the combustion of natural gas and oxygen gas in theratio for complete combustion reaches a temperature of about 2,400 °C. Thus, the use ofa gas mixture containing excess oxygen provides oxygen gas at a high temperature ofaround 2,000 °C. This treatment increases the slag temperature and almost completelyconverts sulfides into oxides.

【問 4】
Surface Energy of Imprint Mold
The contact angle was first measured with a CA-S150 contact angle meter available
from Kyowa Interface Science Co., Ltd. Specifically, an imprint mold was set on ahorizontal measurement stage. Droplets of polar and nonpolar solvents with diametersof not more than 2 mm were dispensed with a droplet dispenser onto a flat portion of thesurface of the surface layer of the imprint mold where no master fine pattern wastransferred. The polar solvent used was deionized water, whereas the nonpolar solvent
used was n-decane. Each deposited droplet was then viewed along the surface of thesurface layer, and the angle θ made by the surface of the surface layer and a straightline connecting the contact point between the leftmost (or rightmost) end of the droplet
and the surface of the surface layer with the apex of the droplet was measured. Theangle θ was measured a total of five times, and these measurements were averaged todetermine the contact angle. The contact angle was used to calculate the surface (free)energy from Fowkes' equation and Young's equation.
