A hopper having a passage through which a medicine can be passed downward is provided. A part of a lower portion of the hopper is a deformable portion having flexibility, and the deformable portion is deformable so as to open and close the passage. According to this configuration, the deformable portion that is a part of the hopper is deformed to open and close the passage. Thus, there is no portion such as an opening and closing plate on which the medicine remains, thereby preventing a gap in which the medicine remains from being formed in the hopper, and preventing the medicine from easily remaining in the hopper.

The present invention relates to a method of cooling a static electronic power converter device including at least one electrical circuit including an assembly of active components and of passive components mounted in a closed radiator housing from which only the inlet and the outlet of the circuit communicate with the outside of the housing, in which the distribution of the heat energy given off by the active and passive components is made uniform throughout the inside volume of the housing, and the heat energy is transferred from the radiator housing by forced convection in substantially uniform manner over the entire inside surface of the walls of the housing by causing at least one fluid contained inside the leaktight housing to circulate in a closed circuit.

The present invention relates to an energy conversion substrate using a liquid and, more specifically, to an energy conversion substrate using a liquid capable of converting mechanical energy into electric energy through a flow of a liquid on a substrate having an energy conversion layer. Thus, the present invention enables easy manufacture and easy liquid circulation to be obtained by implementing an energy conversion device using a liquid through one substrate instead of a pair of opposing substrates and can implement the energy conversion device without a lubricating layer.

The invention relates to a device (1) for producing radioisotopes by irradiating a target fluid using a particle beam (13). This device comprises an irradiation cell (7) that includes a cavity (3) for receiving the target fluid. A non-cryogenic cooling device cools the walls of the cavity (3). The cavity (3) has an inclined surface (15) downwardly delimiting the cavity (3) so as to evacuate the target fluid, which condenses on contact with the cooled walls, under gravity towards a metal foil (4) which closes off this cavity (3). The inclined surface (15) intersects the plane formed by the metal foil (4), making an acute angle (a) with said plane, so as to form with the metal foil (4) a wedge-shaped zone (18) capable of collecting, by gravity, the condensed target fluid.

A reactor includes a tubular-shaped housing in which a stack of filter plates can be rotationally arranged. The cross-sectional area of the reactor container is, in the region of the stack of filter plates, a maximum of 40% greater than the cross-sectional area of the stack of filter plates. The longitudinal extension of the reactor housing is a multiple of the longitudinal extension of the stack of filter plates, such that inside the reactor, adjacent to the stack of filter plates, additional processing devices can be arranged. The rotating stack of filter plates ensures that the entire reactor is cross-flown in an intensive manner.

A drilling method in which a rotary drill bit is mounted on a tubular drillstring extending through a bore comprises: drilling through a formation containing fluid at a predetermined pressure; circulating drilling fluid down through the drill string to exit the string at or adjacent the bit, and then upwards through an annulus between the string and bore wall; and adding energy to the drilling fluid in the annulus at a location above the formation. The addition of energy to the fluid in the annulus has the effect that the pressure of the drilling fluid above the formation may be higher than the pressure of the drilling fluid in communication with the formation and that predetermined differential may be created between the pressure of the formation fluid and the pressure of the drilling fluid in communication with the formation.
