摘要:
The present invention provides a method for producing an inorganic fine particle comprising the step of: reacting two or more reaction solutions for forming an inorganic fine particle while the reaction solutions flow in a non-laminar flow state in a microchannel, thereby form the inorganic fine particle, and an inorganic fine particle produced by the production method. The method for producing an inorganic fine particle of the present invention can stably produce monodisperse inorganic fine particles of nanometer size and allows for flexible response to formulation conditions (e.g., varying flow rate ratios between reaction solutions to be mixed) and for high-throughput production.

A method and an apparatus for precisely controlling flow rate of reactant solution such as silver nitrate solution or halide salt solution which is added into a precipitation vessel. The method comprises applying a pressure to each source of said two solutions and controlling both said applied pressure and a flow resistance of each feed lines of said two solutions so that each flow rate of the two solutions to be added into the precipitation vessel can be adjusted to a predetermined value. The apparatus comprises a storage vessel for the reactant, a feed line to feed the reactant into the precipitation vessel and a flow rate controller, wherein the storage vessel is connected to a pressure controller which includes a pressure vessel pressurized with air or other gases and a pressure control valve, the feed line has a pressure sensor for detecting a pressure inside the feed line, a flow meter and a flow path opening controller along its line in order, the flow rate controller controls the flow rate of the reactant fed into the precipitation vessel by controlling the pressure control valve and the flow path opening controller.

According to this invention, a plurality of indoor units each having an indoor heat exchanger are connected to a heat source unit having a compressor and a water heat exchangers, thereby constituting a multi-type air-conditioning apparatus. The heat source unit has an operation switch operated when a refrigerant amount is to be checked. When the operation switch is turned on, the refrigerant discharged from the compressor is circulated in only the heat source unit. At this time, the temperature of predetermined positions in the heat source unit is detected by a temperature sensor, and it is determined, in accordance with the detection temperature, whether the refrigerant amount in a refrigerating cycle is normal or abnormal. The determination result is displayed on a display unit of the heat source unit.

摘要:
A flow control having a wide flow rate range and excellent linearity between the degree of valve opening and flow rate. The valve includes a cylindrical or conical valve head formed on a circular-truncated-cone-shaped working face which is tapered towards the outlet of the valve with the valve head being located inside the outlet-side casing. With respect to the area of the valve opening defined by the valve head and the valve seat, the valve head is shaped so that the rate of change of the flow rate with valve stroke is small and linear, whereby fine control of the flow rate can be accurately achieved over the entire flow rate range. The valve stroke to fully open the valve occurs in the inlet-side casing. A servo motor or the like is employed as the drive source for operating the valve.
