An air cleaner includes a centrifugal fan runner equipped with backward blades, a core plate connected to an axis of a motor; and a side plate being opposing the core plate. The backward blades, being inclined in an anti-rotational direction thereof, are provided at a distance in a circumferential direction, and the backward blades are bent in a position at distance of about &frac12;-1/(3.5) of a length of the blade from an outer periphery thereof, so that an outlet portion thereof is inclined into a direction of rotation of the blade. An outlet angle of the outlet portion with respect to a tangential direction on an outer periphery of said side plate lies from about 40 degree to about 60 degree.

Centrifugal fan runner and air cleaner

A centrifugal fan runner, equipped with backward blades, being suitable to be applied to, in particular, an air cleaner, an air conditioner, and a fan for air blow and ventilation, with high fan efficiency, a large air volume, low noises, comprising: a core plate being connected to an axis of a motor; and a side plate being provided opposing to said core plate, wherein backward blades, being inclined in an anti-rotational direction thereof, are provided at a distance in a circumferential direction, and the backward blades are bent in a position at distance of about &frac12;-{fraction (1/(3.5))} of a length of the blade from an outer periphery thereof, so that an outlet portion thereof is inclined into a direction of rotation of the blade, and an outlet angle of the outlet portion with respect to a tangential direction on an outer periphery of said side plate lies from about 40 degree to about 60 degree.

An air cleaner includes a housing having an upper wall and side walls, an air filter mounted with respect to the housing, a fan including a vane-wheel having a plurality of vanes, a supporting plate extending substantially between at least two side walls for supporting the fan. An air flow directional member directs an air flow output from the fan. The vane is formed to have a winglike cross-section, and the vane-wheel includes not more than four vanes. The vane-wheel has a base plate and a shroud. Each of the base plate and the shroud is formed to have a reinforcement portion on its circumference. A U-shaped balance weight is attached to a flattened portion formed on the curled portion. The air cleaner of the present invention can reduce noise and vibration and improve efficiency of the fan.

Air cleaner having vanes with a winglike cross-section between a shroud

An air cleaner of the present invention includes a housing having an upper wall and side walls, a fan, a supporting plate extending between the two side walls for supporting the fan, a first air flow directional member extending between the supporting plate and the upper wall, and a second air flow directional member provided at a horizontal periphery of the housing. The first air flow directional member not only provides reinforcement to the supporting plate and the upper wall, but also directs an air flow output from the fan. The second air flow directional member has a horizontal plate and vertical plates for directing air flow at the horizontal periphery of the housing. The first air flow directional member and the second air flow directional member are adapted to equalize a velocity of an air flow distributed across an air flow output area of the fan unit. The supporting plate and the first air flow directional member are adapted to maintain a predetermined spacing between a predetermined portion of the fan and the first air flow directional member. The air cleaner of the present invention can reduce energy consumption by improving efficient of the fan.

A method of measuring the activity of interferon-.alpha., .beta. or .omega., which comprises bringing a sample containing interferon into contact with a cell and determining an induced protein is provided.

Method of measuring interferon acitivity

A forced air cooling apparatus having a blower for blowing air taken in from an intake surface or inlet of the blower to be blown against an electronic device in an installation wherein the blower is mounted for operation on a casing or a rack, and in which the apparatus has a flow regulating plate vertically intersecting the intake surface that is installed immediately before the intake surface. With this construction, eddy air current flow in the vicinity of the intake surface is prevented and the cooling ability obtained from the blower is optimized to thereby attain the effect that the electronic devices can be efficiently cooled without requiring the same separation distance between an intake surface of the blower and a wall surface of the frame or casing in which the blower is installed, as compared with a conventional installation of the same equipment in the same casing without the flow regulating plate.

Porous solid formulations containing proteinaceous physiologically

The present invention relates to a sustained-release injection, which comprises a suspension of a powder comprising an active ingredient and a pharmaceutically acceptable biodegradable carrier (e.g. proteins, polysaccharides and synthetic high molecular compounds, preferably collagen, atelocollagen, gelatin, and a mixture thereof) in a viscous solvent for injection (e.g. vegetable oils, polyethylene glycol, propylene glycol, silicone oil, and medium-chain fatty acid triglycerides). The sustained-release injection can release the active ingredient at an effective level for a long period of time when injected.

Sustained-release injection

A controlled release formulation which comprises a compound selected from the group consisting of organic acidic compounds and acid anhydrides or esters capable of generating one of the organic acidic compounds through hydrolysis together with an active ingredient and collagen as a carrier, said formulation being capable of exhibiting a predetermined release profile of the active ingredient. A process for producing said formulation is also provided.

Controlled release formulation

A preparation administrator has an administrator body including a solid preparation and having at its one end an inflow channel for solvent and at the other end an outflow channel for liquid preparation, a solvent container containing a solvent to dissolve, disperse or suspend the preparation and being connected to the inflow channel of the administrator body, and an ejector for ejecting the solvent together with the solid preparation in the body through the outflow channel of the body. A solid preparation in the administrator body is dissolved, or suspended or dispersed in the solvent fed from the solvent container and ejected as a liquid preparation through the outflow channel of the body.

Pharmaceutical preparation administrator

A solid sustained-release preparation in the form of a needle-like or bar-like shape, which consists essentially of an active ingredient and a pharmaceutically acceptable biodegradable carrier (e.g. proteins, preferably collagen, gelatin, and a mixture thereof). The sustained release preparation can be administered to the body or implanted into the body by injection or an injection-like method and can release the active ingredient at an effective level for a long period of time when administered.

Long-term sustained-release preparation

The invention relates to sustained pulsewise release pharmaceutical preparation which comprices drug-containing polymeric material layers (layers A) and polymeric material layers containing the drug in question only in a slight amount or free of the drug (layers B) disposed alternatingly, with the whole surface extending in the direction perpendicular to the layer plane being coated with a polymeric material which is insoluble in water or scarcely soluble in water (polymeric material C). This pharmaceutical preparation of this invention is designed so that active ingredients which should desirably be released pulsewise can be released therefrom in a pulse-like and clinically significant manner and thereby the pharmacological effects of said active ingredients can be maintained for a prolonged period of time.

Sustained pulsewise release pharmaceutical preparation

A sustained release composition applicable for human beings and mammals which comprises (a) a silicone elastomer and (b) a pharmaceutical substance optionally with (c) albumin. When the pharmaceutical substance is of high molecular weight, and can exert its pharmaceutical effect in a trace amount, its continuous release over a long period is attained by application of this invention.
