Abstract: A pneumatic tire includes a cylindrical annular structure disposed around a rotational axis; a carcass portion including a rubber covered cord, at least a portion of the carcass portion being disposed to the outer side of the annular structure in a direction parallel to the rotational axis; and a rubber layer including a tread portion, at least a portion of the rubber layer being disposed to an outer side of the annular structure in a radiation direction with respect to the rotational axis. In such a pneumatic tire, SW/OD?0.30 is satisfied, where SW is a total tire width and OD is a tire outer diameter.

Abstract: A game piece and game board assembly includes a game piece body having a weight mounting section. A weight member can be mounted at various locations on the weight mounting section to vary the center of gravity. The game piece can strike an opponent's game piece on a game board to score points. A cover can obscure the location of the weight member on the game piece.

Abstract: A toy dump arranged so as to be suitably applied to children of today. The toy dump includes a dump body and a weight member detachably mounted on the dump body. The dump body is formed into a plate-like shape and provided with at least one mounting section for detachably mounting the weight member therein.

Abstract: An information management apparatus dealing with waste in a waste recycling system comprises an information management device for managing information on waste of each depository, and a device of determining the waste collection method based on the information and the process volume of a recycling processor. The apparatus determines the waste collection method so that recycling products can be delivered stably.

Abstract: Projections are removed from the surfaces of ion exchange resin particles by contacting the resin particles with a liquefied gas or supercritical gas in advance. The ion exchange resin thus prepared can remove ions from raw water so thoroughly that the water quality can be improved to that of ultra-pure water.

Abstract: The present invention relates to an apparatus for removing suspended matter, organic matter and nitrogen compounds in the sewage. A processing tank is provided with a floating-separation zone at the upper portion thereof and an electrolysis zone below the floating-separation zone. A bed of porous adsorbent is disposed in the electrolysis zone and electrodes are disposed among the adsorbent. Bubbles generated upon the feed of current to the electrodes rise up through the floating-separation zone to remove the suspended matter and the organic matter in the sewage before introducing the sewage into the electrolysis zone. The porous adsorbent is polarized by the feed of current to the electrodes and results in removing matter remaining in the sewages, especially nitrogen compounds.

Abstract: The present invention relates to a method for removing suspended matter, organic matter, foaming matter and nitrogen compounds in sewage and to an apparatus for the method.The suspended matter and the organic matter are removed by means of first fine bubbles and the foaming matter is removed by means of second bubbles having a larger bubble average diameter. The sewage treated by the first and second bubbles passes through a bed of porous adsorbent polarized by the feed of current, so that nitrogen compounds and the organic matter remained in the sewage are adsorbed and removed. It is also provided with a step for removing the suspended matter and the organic matter remained in the sewage by means of third fine bubbles before transferring the sewage to the bed of adsorbent.

Abstract: A method of regenerating zeolite by heating wherein zeolite having adsorbed (NH.sub.3 -N) in foul water has sodium hydroxide added thereto, the sodium hydroxide containing Na.sup.+ equivalent to NH.sub.4.sup.+ adsorbed to the zeolite, water is added until the total quantity of the zeolite is submerged, and the resultant zeolite is heated at 400.degree. C. for 30 minutes, whereby a regeneration rate of 90% is attained.

Abstract: In regenerating an adsorbent by eliminating water and an adsorbed matter which are contained therein, the adsorbent is indirectly heated while descending within a drying furnace and is indirectly heated while ascending within a regenerating furnace in order to prevent the adsorbent from scattering due to water vapor and the adsorbed gas separated by the heating of the adsorbent and to prevent the adsorbent from burning itself due to heat.

Abstract: An apparatus for separating non-magnetic materials of different densities, which apparatus includes a material separating portion, in which a magnetic fluid is retained in a magnetic field having a gradient in a vertical direction. In this apparatus, a single conveyor is jointly used for the supply, and charging of materials to be separated, into the material separating portion, and the transporting of floating materials of a low density through the magnetic fluid and their recovery outside.
