摘要： A coated or encapsulated granular fertilizer which comprises an olefin polymer and/or copolymer and a polyether polyol in a defined amount. The olefin polymer is an ethylene or propylene homopolymer and/or a copolymer of an olefin monomer and a copolymerizable monomer such as olefinic monomers, vinyl acetate and carbon monoxide. The polyether polyol is polymers of ethylene oxide, propylene oxide and mixtures thereof with or without etherification with polyhydric alcohols. By the addition of the polyether polyol, a dissolution rate of the fertilizer can be arbitrarily controlled without a sacrifice of physical properties of the coated film.

摘要： A thermal power transfer system using a phase change liquid gas fluid in a closed loop configuration has a heat exchanger member connected to a gas conduit for inputting thermal energy into the fluid. The pressure in the gas conduit is higher than a liquid conduit that is connected to a heat exchanger member for outputting thermal energy. A solid electrolyte member acts as a barrier between the gas conduit and the liquid conduit adjacent a solid electrolyte member. The solid electrolyte member has the capacity of transmitting ions of a fluid through the electrolyte member. The ions can be recombined with electrons with the assistance of a porous electrode. An electrical field is applied across the solid electrolyte member to force the ions of the fluid from a lower pressure liquid conduit to the higher pressure gas conduit.

摘要： A wide range electric resistance type moisture meter is disclosed wherein a current flowing through a sample such as grain or wood is scaled by a load resistor and a feedback resistor of an operational amplifier to derive a scaled current which is proportional to the sample current, and the scaled current is current-voltage logarithmic-converted by a logarithmic conversion circuit including another operational amplifier connected to the output of the first-mentioned operational amplifier and diodes, so that a moisture content indicating voltage is linearized even in a high moisture content range. The output of the logarithmic conversion circuit is processed by an operation circuit to produce the moisture content and temperature compensated and the resulting moisture content is indicated by a moisture content indicator.

摘要： In an induction machine having power windings disposed coaxially about the iron core thereof, means for reducing an axial mechanical force produced in any given winding by the interaction of the radial components of leakage flux produced at a time of short-circuiting and an electric current flowing in the given winding at that time. The reducing means includes a plurality of loops mounted respectively at the ends of the given winding and adapted to link the radial components of leakage flux produced at the ends of the given winding at the short-circuiting to generate induced currents in said loops. These currents produce magnetic flux for cancelling the radial components of leakage flux, respectively. In order to equalize the quantities of the radial flux components having opposite directions at the given winding to each other to reduce the axial force, one or two search coils are mounted at the ends of the given winding so as to link the radial flux components, respectively and then the windings are axially relatively moved till the difference between the elctromotive forces induced in the search coils becomes zero. If the power windings include a winding of a relatively large radial width, or three or more in number, an auxiliary winding arrangement can be used in order to detect the axial displacements between the electromagnetic median planes of the power windings across the length axes thereof, which planes respectively have equal ampere-turns on either side thereof. The auxiliary winding arrangement is adapted to be disposed coaxially around the outermost power winding and which is adapted to be placed in electromagnetically coupled relationship to a given one of the power windings which is being excited, thereby to produce a magnetic flux having opposed radial components linking the search coils.
