Abstract: Mulling contents of an intestine 12 and a gas-liquid mixture is promoted to increase a contact area between adventitious moisture and detained feces at an increasingly fast rate, thereby fluidizing the detained feces. The use of a liquid component and a gas component in combination enables development of an adventitious liquid component to the entire intestine while discomfort and ache are suppressed. As a result, increase in total excretion amount of liquefied detained feces is reduced. Injection and discharge control of the adventitious component enables coping with various defecation impairment.

Abstract: A multiple-position solenoid-operated control valve having a valving member in the form of a spool fitted in a valve body so that it is normally held at its normal position by a first spring and slidably movable at least to two or more operated positions on one side of the normal position. The spool is moved by a movable iron core upon energization of a solenoid which produces actuating forces of different magnitudes increasing in at least two steps including a first operating force to move the spool to the first operated position against a first biasing force of the first spring, and a second operating force greater than the first operating force. At least a second spring is provided to cooperate with the first spring to hold the spool at the first operated position against the first operating force until the second operating force is produced.

Abstract: Scrap of thermosetting plastics is reclaimed and recycled by an integrally combined apparatus including means for pulverizing scrap into atomized powder and means for mixing and agitating the atomized powder with a virgin material at a desired ratio. An improved recycling apparatus for thermosetting scrap comprises compactly a pulverizer, an atomizer, a mixing device to mix uniformly atomized powder with virgin material, and a purifying device for Noxious gas generated during pulverizing process.
