摘要:
A liquid or powder measurement apparatus, usable also for mixing a plurality of measured materials and for distributing the mixture to a plurality of dispensing containers. A flow control valve having a wide flow rate range and excellent linearity between the degree of valve opening and flow rate is disposed in each of the liquid flow paths and is adjustable to have a flow rate linearly varying with the stroke of the valve. A mixing container receives the raw material from one or more supply containers and is weighed by a load cell to thereby detect the amount of material flowing into or out of the mixing container. A control unit operating according to fuzzy logic compares the measured weight with a target weight and accordingly adjusts the flow rate of a selected one of the flow regulators. The same load cell and control unit can also control the flows from the mixing containers to the dispensing containers.

The present invention relates to a device for preparing a photographic liquid which is to be applied in the manufacture of a photographic photosensitive material wherein multiple layers of photographic liquids are applied simultaneously. The present invention has at least one chemical measuring station which measures various kinds of chemicals sent from chemical storage tanks and prepares a photographic liquid which is to be applied to a film, supplies the measured chemicals to a pot and a conveys the chemicals in the pot to a hopper from which the chemicals are supplied to a liquid preparation tank.

A process for preparing an oil-in-water emulsion is described, comprising the steps of: adding a mixture of a hydrophobic substance and an emulsifying agent directly or after being dissolved in an organic solvent by heating in a dissolving-emulsifying tank with a high-speed agitation type dispersing means to form a hydrophobic substance solution as an oil phase, introducing water and/or an aqueous solution of gelatin into the tank through submerged inlet under the hydrophobic substance solution to form a water-in-oil emulsion, and further continuing the addition of water and/or an aqueous solution of gelatin to cause the phase inversion, whereupon the desired oil-in-water emulsion is formed. The mean particle size of the emulsion is decreased more than by the conventional emulsification method, and the particle size distribution is narrowed and made sharp.

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.

A method for detecting an analyte in a sample liquid, using a detection reagent which reacts specifically with the analyte to give structural information on the analyte, comprising the steps of: a step of dropping the sample liquid containing the analyte onto a substrate and evaporating a solvent in the droplet by feeding a gas to the droplet; and a step of contacting the droplet with the detection reagent.

According to the present invention, a continuous layer liquid used as a continuous layer of a diffusion phenomenon is injected into the first reservoir, and passed through the channels to the second reservoirs to fill the plurality of radially formed channels with the continuous layer liquid. Then, a predetermined amount of diffusion experiment reagent, for example, a coloring liquid used as a diffusion substance of the diffusion phenomenon is injected into the first reservoir. This causes the diffusion experiment reagent to be diffused from the first reservoir to the second reservoirs only by the diffusion phenomenon. At this time, the radially formed channels have the different sectional areas, and thus the diffusion experiment reagent is diffused through the channels at different velocities. This allows the diffusion phenomena that occur in the micro channels or the diffusion velocities to be observed or measured with ease using an inexpensive device.

According to a blood plasma collection tool of the present invention, a phenomenon that blood cells in blood spontaneously precipitate due to an effect of gravitational force takes place in the very narrow microspace (separation part) having the very narrow depth in the direction of gravitational force of not greater than 1 mm, and the overflow channel functions as a dam against the separation part so that the blood plasma separated out as supernatant fluid can overflow beyond the overflow channel, whereby the blood cells separated out can be prevented from entering the collection part. Therefore, blood plasma can be collected by accurately and readily separating blood plasma and blood cells in a small amount of blood from each other in a short time, using a small tool having a simple structure.

At least one of a nucleus forming process, a nucleus growing process, a chemical sensitizing process, and a spectral sensitizing process for producing a silver halide photographic emulsion is performed by using a microreactor. A minute region of the microreactor is used to precisely perform a reaction of nucleus formation. A condition under which host grains are allowed to react with newly supplied silver halide nuclei is made uniform to cause uniform crystal growth. A predetermined quantity of molecules for chemical sensitization is doped in a crystal lattice of a nucleus of silver halide to effect a sensitizing process. Alternatively, a spectral sensitizing process in which a single molecular layer of a spectral sensitizer is uniformly adsorbed on a silver halide nucleus grain surface is securely carried out.

An outdoor unit (1) of an air conditioner comprises a unit case having a rectangular shape in section and composed of side panels (4, 4, - -) in which a machine chamber (3) and a heat exchanger chamber (2) are defined so as to be vertically aligned in an installed state with the heat exchanger chamber being disposed above the machine chamber and being sectioned therefrom by means of a partition plate (12) which also acts as a drain plate or pan, and the side panels surrounding the heat exchanger chamber is formed with air suction ports (4a, 4a - -). The outdoor unit (1) further comprises a heat exchanger unit (17, 18) having four side wall sections at least opposing two of which are inclined inward by a predetermined angle with respect to inner surfaces of the side panels to which the air suction ports are formed. Thus, the outside air can be effectively and smoothly introduced inside the outdoor unit. The outdoor unit is also provided with a duct unit (20) arranged in the unit case in association with the drain pan (12) for effectively discharging drain, cooling electrical part such as heat sink (22) and improving the outer appearance of the outdoor unit.

Two or more indoor units are provided on ceiling and floor of a room. Each of the indoor units has an air heat exchanger for cooling indoor air, and a drain pan for catching drainage produced by the air heat exchanger. A drain pipe is provided in the ceiling and under the floor. The, drainage in each of the drain pans flows into the drainage pipe. The drain in the drain pipe is carried and discharged outdoor by a drain carrying unit.
