Title: Method for detection of installation position of driving shaft system in marine propelling device
Inventor: SUGIMOTO IWAO
IPC: B63B9/00
Filed: 2002-04-18
Granted: 2003-01-11
Abstract: The installation height of the bearing devices other than the basic reference bearing device of the proper shaft and the crank shaft is provisionally set as reference data, and the crank deflection at each crank throw and the bearing load on the propeller shaft are calculated by using a transmission matrix method based on the data of the installation height. Thereafter, an evaluation value is calculated based on the difference between the calculated deflection and the calculated bearing load and the actually measured, tested deflection value and tested bearing load is calculated. The evaluation value is compared with an allowable value, and if the evaluation value exceeds the allowable value, a provisional installation light in the binary form is newly prepared by using a genetic algorithm, and a new evaluation value is calculated based on the new installation height data. This process is repeated until the evaluation value falls within the allowable value.

Title: Reaction-sintering process for perovskite Pb(Mg1/3Nb2/3)O3 and Pb(Fe1/2Nb1/2)O3 ceramics
Inventor: LIOU YI-CHENG
IPC: C04B35/495
Filed: 2002-05-15
Granted: 2004-05-21
Abstract: Pb(Mg1/3Nb2/3)O3 (PMN) and Pb(Fe1/2Nb1/2)O3 (PFN) have been reported difficult to produce as single-phase perovskite ceramics by traditional oxide route due to the appearance of stable pyrochlore phases. Swartz and Shrout proposed a columbite/wolframite route to produce 100% perovskite PMN and PFN. PMN (PFN) powders are prepared by first mixing and reacting MgO (Fe2O3) and Nb2O5 at 1000 DEG C for 4h to form columbite (wolframite) precursor MgNb2O6 (FeNbO4). Then reacted with PbO at the second calcining stage. After sintering, perovskite PMN (PFN) ceramics are produced. In this reaction-sintering process, no calcining stage is carried and a mixture of raw material powders is pressed and sintered directly to form pyrochlore-free PMN and PFN ceramics. This process is simpler than the columbite and wolframite route. PMN ceramics produced by reaction-sintering process and sintered at temperatures 1250 DEG C and 1270 DEG C for 1h, 2h and 4h are all pyrochlore-free. Density reaches 8.09 g/cm<3> and maximum dielectric constant under 1kHz is higher than 18500. As for PFN ceramics, 100% perovskite phase ceramics are obtained after sintering at temperatures between 1120 DEG C and 1210 DEG C for 2h and 4h. Density of 8.25 g/cm<3> is obtained in PFN ceramics.

Title: Hydrophilic silicone elastomer material usable especially for taking dental impression
Inventor: TORTO MARCO DEL

Filed: 2002-06-10
Granted: 2007-01-21
Abstract: The invention relates to a crosslinkable silicone material made of a silicone elastomer by polyaddition reactions, usable especially for taking impressions, for example dental impressions. The objective is to obtain a material making it possible in particular to achieve a pronounced level of hydrophilicity by obtaining contact angles theta (cf. figure 1 in which reference 1 represents the surface of a film of the crosslinked silicone material and the reference 2 represents the drop of water deposited on the said surface) which can be as low as those ranging from 25 to 27 DEG. The invention relies in particular on the introduction, into the crosslinkable silicone material of: (a) at least one nonionic surfactant consisting of an ester obtained by esterification of a C10-C14 fatty acid by a poly(oxyalkylene) glycol of low molecular weight; or a synergistic combination (a)+(b), where b denotes at least one nonionic surfactant consisting of a polyalkoxylated C5-C16 fatty alcohol of low molecular weight. The intended applications relate to the use of the silicone material for taking impressions, for example dental impressions, and for the manufacture of moulded parts, other than duplicates in dental applications, which are capable of developing a pronounced hydrophilic and/or antistatic character on the surface.
