Abstract: An apparatus for examining urine for certain constituents thereof includes a vertically disposed cylinder for receiving urine therein. The cylinder includes a diametrically enlarged upper portion having an inside diameter which is larger than that of its remaining portion. A piston is vertically movably disposed in the cylinder. If the piston is lowered, urine can be stored in the cylinder. If it is raised, the urine is discharged from the cylinder, except that only a small portion thereof remains in a clearance defined between the piston and the diametrically enlarged portion of the cylinder. If the piston is lowered again, a reagent and water are supplied into the cylinder and mixed with the urine remaining therein. An electrode is connected to the cylinder for determining the concentration of sugar, etc. in the urine which has been mixed with the reagent and water.

Balls (60, 62, 160B, 160C) capable of plugging up the exit ports in the outer surface are mounted in the valve casing (38). The valve member (40) has arms or cams for moving the balls. The exit port in the end surface is opened and closed by the valve member (40) or one ball (160C).

Abstract: A method and an apparatus for measuring the concentration values of constituents of urine collected in a toilet bowl. A conduit extends from the urine-collecting portion of the bowl to a concentration-measuring device. A gas injector is mounted beside the conduit to intermittently inject gas into the conduit, for dividing the urine contained in the conduit into aliquots. The concentration values of urinary constituents of each aliquot are measured.

Further, a water closet unit capable of attaching the same to a toilet room and blowing warm air out, comprising: an adapter having a means for fixing the adapter to the toilet room, and a warm air generator; and a sitting type water closet having a warm air duct for conveying warm air from the generator to a space in front of the water closet; the water closet being attached at the rear portion thereof to the adapter, and furthermore, a prefabricated toilet room unit including the above water closet unit are also disclosed.

Abstract: An apparatus for setting the ion concentration in an ionic water generator which separates drink water between alkaline ionic water and an acidic ionic water by applying a DC voltage between electrodes in an electrolytic cell which are partitioned by an ion-exchange membrane apparatus comprises a device for measuring voltage drop at a portion leading to the electrolytic cell which is caused when a reference voltage is applied, and a calculator for calculating voltage Vx which is applied to the electrolytic cell to adjust ion concentration to a desired value from a proportion k of the voltage drop which is calculated by application of the reference voltage to water to be examined relative to the reference voltage drop caused by application of the reference voltage to reference water and a set voltage Vn which corresponds to the desired ion concentration on the basis of the following equation:Vx=k.times.Vn.

Abstract: The present invention relates to a solenoid valve disposed over a fuel tank and incorporating a liquid surface detecting valve for detecting the liquid surface in a fuel tank. The solenoid valve comprises a plunger and an adhesion preventive pin wherein the adhesion preventive pin is lowered in the direction of the liquid surface detecting valve at the time of opening of the solenoid valve and the same pin pushes the liquid surface detecting valve downward at the time when the liquid surface detecting valve is attached and adhered to a valve seat thereof, whereby the liquid surface detecting valve is open with assurance.

Abstract: This invention relates to an impulse wrench which has two blades but generates only one impact pulse on the main shaft per one rotation of a liner. In this invention, a liner has at least four seals and a main shaft has at least two seals. And the shape of both or one of the two seals out of at least two seals of main shaft is other than a linear shape parallel to the axial center.If both of said two seals of main shaft are in said shape, two of at least four seals of liner are in the same shape. The other seals of liner are in a linear shape parallel to the axial center.If one of said two seals of main shaft is in said shape, one of at least four seals of liner is in the same shape as this. All of the other seals of liner are in a linear shape parallel to the axial center.In this way, said two seals of liner and said two seals of main shaft coincide with each other only once per one rotation of the liner.

Abstract: A dry grouting agent comprises cement particles having baked on the surface thereof a coating including a water-soluble silicon resin and a surface active agent. The grouting agent is produced by preparing a liquid mixture including a water-soluble silicon resin, a surface active agent and an oily solvent, adding the liquid mixture to cement particles and uniformly kneading it therewith, heating the result to evaporate off the oily solvent and water and to bake onto the cement particles a coating layer containing the water-soluble silicon and the surface active agent, and cooling and pulverizing the resulting solid mass.

Abstract: An improved wippen heel arrangement for an upright piano includes: a pillar screwed into one end portion of a piano key so that the projecting length of the pillar which projects from the piano key is adjustable; a wippen heel attached to a wippen constituting one element of an action mechanism; and a wippen joint interposed between the pillar and the wippen heel for pivotal movement about a stationary shaft, in which the thrust applied to the pillar is transmitted through the wippen joint to the wippen. Accordingly, a key touch quality which may be experienced with a grand piano can be enjoyed using an upright piano.

Abstract: A gas-liquid contacting apparatus according to the present invention comprises a gas channel, a blowing device, a screen, a liquid feeding device and a pump. The screen is supplied continuously with liquid by means of the pump and the liquid dosing device, forming liquid film in intervals where gas passes through all the time. Gas fed out of the blowing device breaks through said liquid film or screen. In this moment, the gas-liquid contact is completed as the specific components contained in the gas are chemically decomposed and removed, being diffused in liquid. The liquid film is broken and re-formed repeatedly while the gas flows.
