Abstract: A spherical puffing pump for an ice cream machine and an air inlet device thereof. The spherical puffing pump includes a spherical pump body, a clamping plate and an air inlet valve. A liquid feeding hole of the spherical pump body is connected to a milk slurry tank to feed milk slurry. The air inlet valve is connected to a channel of the liquid feeding hole to introduce air. A liquid discharging hole is connected to a liquid inlet of a refrigerating cylinder. A pump seat is fixed on the ice cream machine. An end portion of the pump seat protrudes from an inner wall of the tank. A cylinder of the spherical pump body is connected to the end portion through the clamping plate. A main shaft of the spherical pump body is connected to a motor shaft through a connecting shaft for power transmission.

Abstract: Disclosed are a hydrostatic pressure support and a spherical pump having the same. The hydrostatic pressure support is arranged between each of two parallel sides of a slipper and a sliding groove, and includes a first liquid flow channel, a second liquid flow channel, and a pressure-bearing groove. An inlet of the first liquid flow channel is communicated with one of two working chambers of the spherical pump, and an inlet of the second liquid flow channel is communicated with the other of the two working chambers. An outlet of the first liquid flow channel and an outlet the second liquid flow channel are respectively communicated with the pressure-bearing grooves provided on the two parallel sides of the slipper.

Abstract: This invention provides a fine particle composite comprising fine powder of a sulfide or sulfide complex comprising a given element. The fine particle composite is obtained by a method for producing a fine particle composite comprising fine powder of a sulfide or sulfide complex comprising at least one element selected from the group consisting of molybdenum (Mo), rhodium (Rh), ruthenium (Ru), and rhenium (Re). Such method comprises steps of: preparing a solvent mixture from at least one compound containing an element selected from among molybdenum (Mo), rhodium (Rh), ruthenium (Ru), rhenium (Re), and sulfur (S); and subjecting the solvent mixture to a hydrothermal or solvothermal reaction. The resulting fine particle composite comprises fine particles of a sulfide or sulfide complex comprising at least one element selected from the group consisting of molybdenum (Mo), rhodium (Rh), ruthenium (Ru), and rhenium (Re).

Abstract: According to the present invention, a fluorescent powder composed mainly of an acicular or fibrous zinc oxide single crystal with an aspect ratio of 5 or higher is produced by the following steps: a step of producing a raw material solution selected from the group consisting of a raw material solution (A) that is an alkali solution containing zing ions, a raw material solution (B) that is a solution containing zinc ions and ions of dopant element, and a mixed solution of the raw material solution (A) and the raw material solution (B); and a hydrothermal reaction step wherein a hydrothermal reaction of the mixed solution is carried out in a hermetically sealed vessel at a subcritical or supercritical temperature and at a subcritical or supercritical pressure. A zinc oxide single crystal powder can be produced at low cost without the need for a pulverization step or a similar step and high-density orientation can be realized by such crystal powder.
