Abstract: A vacuum kneading and deaerating device has a rotatable body provided in a chamber held under a closed or pressure-reduced condition, and which is rotated in a horizontal plane around a basic driving rotation axis. A container holder is provided in the chamber rotationably on an operating rotation axis parallel to the basic driving rotation axis in a revolution edge portion of the rotatable body, and detachably holds a paste container such that a central axis of the paste container obliquely intersects the operating rotation axis. A driving mechanism rotates the rotating body and the container holder. A deaeration valve for opening an internal space of the paste container to an internal space of the chamber by the action of centrifugal force attending on the rotation of the paste container, or a paste material-impermeable and gas-permeable membrane, is provided in an opening portion of the paste container.

Abstract: Disclosed herein is a plasma generator, in which a plasma forming space, into which the air is introduced, is provided, band plate-like first and second electrodes are arranged in opposed relation to each other through a dielectric in the plasma forming space, and plasma is generated by discharge caused by applying voltage between the first and second electrodes, wherein the first and second electrodes are arranged in a state relatively displaced in a surface direction of the dielectric so as to satisfy the specific relationship.

Abstract: The paste feeding apparatus is equipped, within a cylindrical container having a paste feeding opening at its lower end, with a spiral pump composed of a vertical mantle tube having a paste inlet and a paste outlet, which are spacedly formed at lower and upper positions, respectively, and a screw shaft provided coaxially within the mantle tube; a drive motor connected to the screw shaft; and a piston moving up and down in an annular space in the container. A raking blade which is connected to the screw shaft and serves to rake a paste in the paste inlet of the mantle tube may be provided. The paste feeding apparatus is composed of a drive section and a pump-container section detachably installed thereto. According to the paste feeding apparatus, the kneading of a paste, the adjustment of its viscosity and the control of its feed rate can be stably achieved with high precision, and hence high reliability can be attained.

Abstract: An automatic urinalysis system which can be readily installed at an excretion site such as a toilet and by which means a subject itself can test its urine easily at any time and can obtain results of such test. The system comprises a sample collecting means for collecting a sample of urine within a stool or the like at an excretion site, a guiding means for introducing the collected urine sample into a testing area within a body of the system, a urine testing element located within the system body, a contacting means for automatically contacting the urine testing element with the urine sample in the testing area, a urine testing means for automatically testing the urine testing element contacted with the urine sample by the contacting means, a display means for displaying test data from the urine testing means, and a discharging means for discharging the urine sample into the stool after the urine sample has been contacted by the urine testing element.

Abstract: A rotating viscometer for a paste is constructed of a rotary member, a stationary member provided in opposition to the rotary member with a small clearance therebetween, said stationary member being displaceable angularly relative to the rotary member, a paste inlet formed in communication with the small clearance to allow the paste to flow into the small clearance upon rotation of the rotary member relative to the stationary member, a paste outlet for allowing the paste to flow out of the small clearance, and a means for sensing a torque applied to the stationary member owing to the viscosity of the paste introduced in the small clearance by the rotation of the rotary member.
