A method of soil improvement work drills the ground with a drilling head arranged at a lower end of a rotary shaft and sends the rotary shaft into the ground. The method mixes pressurized water with compressed air on the ground, to prepare a fluid mixture, feeds the fluid mixture through a feed path arranged along the rotary shaft into an ejector arranged on the drilling head, and ejects the fluid mixture from the ejector toward the ground to drill. An envelope defined by a front end of the drilling head has a conical shape.

A sand pile driving method for making a sand pile which does not cause trouble in terms of strength even at a soft point in the actual ground, and enables secure limitation of the increase in total construction time and total amount of sand. A compaction procedure is a procedure for compacting a granule pile 15 by pressing and rotating the casing pipe 13 downward. This is performed based on thrust force P by which the casing pipe presses a granule pile and a driving torque T for rotating the casing pipe against a granule pile.

A suspension or a particle-solvent mixture system, which contains microparticles of zinc-containing calcium phosphate with particular chemical composition, specifically, microparticles of sparingly soluble zinc-containing calcium phosphate, and a therapeutic agent for treating zinc deficiency are provided. Particulary, a suspension or particle-solvent mixture system is prepared by mixing microparticles of zinc-containing calcium phosphate consisting of from 0.6 ppm to 13% by weight of zinc, 33-57% by weight of P2O5, 10-65% by weight of CaO and 0-28% by weight of H2O with a water-miscible or water-immiscible solvent. Such a suspension or particle-solvent mixture system can be used as a therapeutic agent for treating zinc deficiency.

A sustained release drug carrier comprises a ceramic composite which is formed by bonding a plurality of ceramic bodies together, and drugs impregnated into the ceramic composite. A method of manufacturing the sustained release drug carrier comprises the steps of: (i) preparing ceramic bodies to be bonded together, each of the ceramic bodies having a bonding surface; (ii) preparing a slurry in which primary particles of a bonding ceramics are dispersed; (iii) applying the slurry to the bonding surface of at least one of the ceramic bodies to be bonded; (iv) sintering the ceramic bodies between which the slurry has been interposed to bond them together, to obtain a ceramic composite; and (v) impregnating a drug into the obtained ceramic composite. According to the structure and method described above, it is possible to provide a sustained release drug carrier whose drug release properties can be controlled and which is capable of exhibiting better drug release action suitable for the application sites, type of drugs to be carried, and the like.

A transmission type X-ray tube includes an electrode lead holding a cathode filament and a stem unit to which a sealing member, an exhaust tube, and the like are attached by brazing, and an irradiation window frame having an X-ray irradiation window attached by brazing. The other end side of the sealing member is attached to an open end of the irradiation window frame by welding. Thus, it is possible to obtain a high-quality transmission type X-ray tube having a long service life at a low cost.

An optical disk drive includes a pickup main body that radiates a laser beam to a surface or a region of an optical disk, where no track information is present, thereby recording and/or reproducing predetermined information on the surface or the region, and that is movable in a radial direction of the optical disk, a position sensor for detecting movement and/or a position of the pickup main body, and a control unit that controls the position of the pickup main body and/or an objective lens on the basis of information relating to the movement and/or position of the pickup main body that is detected by the position sensor.

摘要:
Amorphous piretanide having the following characteristics a) exothermic peaks at about 136.degree. C. and about 209.degree. C., b) an endothermic peak at about 207.degree. C., and c) a melting peak at about 225.degree. C. in differential thermal curves; d) a halopattern without diffraction peak in X-ray powder diffraction analysis; and e) characteristic absorptions at around 1700 cm.sup.-1 and 3200-3500 cm.sup.-1 in infra-red absorption spectrum, and having a superior solubility around neutrality and a high bioavailability effective in the manner of oral or injection administration. Methods of preparing amorphous piretanide are also described.
