Abstract: The present invention is hydrophobic silica gels having a reduced surface area and a method for their preparation under natural conditions. The method comprises two steps, where in the first step the pH of a mixture comprising a silica hydrosol and colloidal silica is adjusted with a base to within a range of pH 3 to pH 6 to facilitate formation of a silica hydrogel having incorporated therein colloidal silica. In the second step the silica hydrogel is contacted with an organosilicon compound in the presence of a catalytic amount of a strong acid to effect hydrophobing of the silica hydrogel to form a hydrophobic silica gel having a surface area within a range of about 100 m2/g to 450 m2/g in the dry state. In a preferred process the hydrophobic silica gel is contacted with a sufficient quantity of a water-immiscible organic solvent to convert the hydrophobic silica hydrogel into a hydrophobic silica organogel. A water soluble compound of cerium or iron may be added during conduct of the second step to improve heat stability of the hydrophobic silica gel.

Abstract: A pressure-type flow rate control apparatus for use especially in the gas supply system in semiconductor manufacturing facilities. The flow control apparatus is provided with a bore-variable orifice, which permits easy switching of the fluid flow rate control range as well as size reduction of the pressure-type flow control apparatus, and offers other advantages including improved gas replaceability, prevention of dust formation, and reduced manufacturing costs of the flow control system. The pressure-type flow rate control apparatus comprises an orifice, a control valve provided on the upstream side of the orifice, a pressure detector provided between the control valve and the orifice, and a control unit to calculate a fluid flow rate Q on the basis of a pressure P1 detected by the pressure detector with the equation Q = KP1 (K = constant) and to output in a drive for the control valve the difference between the set flow rate signal Qs and the calculated flow rate signal Q as control signal Qy, wherein the pressure P1 on the upstream side of the orifice is regulated by actuating the control valve for controlling the flow rate of the fluid downstream of the orifice with the ratio P2/P1 between the pressure P1 on the upstream side of the orifice and the downstream pressure P2 maintained at not higher than the ratio of the critical pressure of the controlled fluid, characterized in that a direct touch type metal diaphragm valve unit functions as the orifice and that the ring-shaped gap between the valve seat and the diaphragm serves as variable orifice wherein the gap is adjusted by the orifice drive. <IMAGE>

Abstract: Administration of a radioisotopic compound by infusion over a period of time greater than two hours, preferably greater than twelve hours, greatly increases the maximum radioactivity that accumulates in the target cell. The efficacy of the administration of the radiolabeled compound can be increased about five times higher than prior bolus injection or short infusion methods. This method enhances the tumor to background ratio by increasing the actual  radioligand accumulated inside the tumor cells. This technique works for any radiolabeled compound whose cellular uptake is limited by a cellular process of either binding to a cellular receptor or to a transport protein. Once the radiolabeled compound is bound and internalized, the ability of an unlabeled compound to compete with the radioligand is markedly decreased. The primary factor governing residence time after internalization is the physical half-life of the radioisotope, not biologic half-life.

Abstract: A machine for drilling oil-holes in crankshafts and the corresponding procedure. It can be used to drill one, two or more crankshafts per cycle. Each crankshaft can revolve on its own axis. The unit described is mounted on a horizontally-faced rotary table with vertical rotating axis, to place the crankshafts at different angles to the Z axis of the machining module, maintaining the horizontal position of the longitudinal axes of the crankshafts. Facing the unit is the machining module, provided with two horizontal spindles, drill tool-holders, with their corresponding guide bushings and parallel to each other, one on top of the other, at the same distance as the two crankshafts. The module has movement in three co-ordinates: axis X (horizontal-transverse), Y (vertical ) and Z (horizontal-presenting tools). A fourth axis W, (with additional module and independent action), moves parallel to Z and carries the guide bushings. It is provided with an automatic changeover, (tool+bushing or just the bushing), incorporating simultaneously the pair of spindles.
