Abstract: A method of producing a group III nitride such as aluminum nitride, comprising the step of reacting a group III halide gas such as aluminum trichloride gas with a nitrogen source gas such as ammonia gas in a growth chamber to grow a group III nitride on a substrate held in the growth chamber, wherein the method further comprises premixing together the group III halide gas and the nitrogen source gas to obtain a mixed gas and then introducing the mixed gas into the growth chamber without forming a deposit in the mixed gas substantially to be reacted each other. For the growth of a group III nitride such as an aluminum-based group III nitride by HVPE, there are provided a method of producing the group III nitride having as high quality as that obtained by the method of the prior art at a high yield and an apparatus used in the method.

Abstract: An optical member driving device having a movable member formed integrally with a frame member holding an optical member, without requiring a reinforcement of any abutting regions on the driving friction member is comprising a driving friction member capable of a reciprocation in an axial direction thereof, a movable member formed integrally with a frame member holding an optical member which engages frictionally with the driving friction member, wherein the movable member is made from fiber reinforced polyphenylene sulfide formed with an injection molding process, and an engaging surface of the movable member abutting on the driving friction member is processed so as to remove some material after the injection molding process.

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.
