摘要:
A balloon for a blood vessel-dilating catheter is fabricated from a biaxially oriented film of an aromatic polyamide or an alloy thereof. The balloon has a calculated modulus of elasticity of from 70 to 190 kg/mm.sup.2. When the balloon is fabricated from an alloy of an aromatic polyamide, the alloy may contain up to 50% by weight of an aliphatic polyamide. The balloon of the invention is soft and flexible as well as dimensionally stable. Therefore, the balloon catheter has a high trackability, and may be inserted into the blood vessel without inducing any injury in the inner surface of the blood vessel. The balloon of the invention also has a good blood compatibility.

摘要:
A treatment method of organic compounds included in waste water, comprising the steps of: supplying waste water to an adsorber 2 filled with an adsorbent 3 therein for adsorbing the organic compounds in the waste water by the adsorbent 3 in the adsorber 2, supplying a current between an anode 9 and a cathode 8 in water including an electrolyte in an electrolyzer 6 for electrolyzing the water including an electrolyte, and supplying an electrolyte resulting from electrolysis in the electrolyzer 6 to the adsorbent 3 in the adsorber 2 for contacting the electrolyte with the adsorbent 3, so that the organic compounds adsorbed by the adsorbent 3 are desorbed or decomposed.
摘要:
A method and an apparatus for removing dissolved organic substances from an oily water obtained as a by-product from an oilfield, characterized in that an oily water obtained as a by-product from an oilfield by separating a crude oil from a crude oil/brine mixture is brought into contact with an adsorbent to adsorptively remove organic substances dissolved in the water containing oil suspended therein and that the adsorbent is regenerated.

An apparatus for handling paper sheets and the like has a mechanism for discharging the paper sheets. The mechanism is provided with a scraper for scraping the paper sheets having wound around a wheel from the wheel. The scraper has a tip end and an opposite end that is rotatably supported in a direction close to or away from the wheel so that the tip end can maintain contact with an outer peripheral surface of the wound paper sheets. The scraper includes a first scraper section and a second scraper section. The first scraper section is rotatably supported in the direction close to or away from the wheel, and is urged toward an outer peripheral surface of the wheel. The second scraper section is rotatably supported on the first scraper section in the direction close to or away from the wheel, and is urged in a direction in which a tip end of the second scraper section rotates toward the outer peripheral surface of the wound paper sheets.
摘要:
An indwelling catheter is made of a blend of a plurality of polyurethane resins containing polyglycols having different molecular weights, or a polyurethane resin containing a plurality of polyglycols having different molecular weights. It shows a dynamic storage modulus of 1 GPa or more under a dry condition at 25° C. and decrease in dynamic storage modulus when changed from a dry condition at 25° C. to a wet condition at 37° C., a decrease percentage of the dynamic storage modulus being less than 60% at the elapsed time of 20 seconds and 60% or more at the elapsed time of 1 minute after placed under the wet condition at 37° C. Its Young's modulus is 50 kgf/mm2 or more under a dry condition at 25° C., which reduces to 25 kgf/mm2 or less within 5 minutes when placed under a wet condition at 37° C.

摘要:
A casing body of a transmission casing has an oil pan mounting flange including an oil pan joint surface for joining an end surface of the oil pan, and a housing mounting flange including a housing joint surface for joining an end surface of a housing. The oil pan mounting flange and the housing mounting flange are provided substantially perpendicularly to each other. A reinforcing rib is formed parallel to the oil pan joint surface to reinforce the casing body. A pocket part is formed on the back surface of the reinforcing rib opposite to the direction of the oil pan joint surface, and a processing/assembling reference hole is formed in the reinforcing rib at a location of the rib where the pocket part is formed. As the reference hole is obtained without protruding the flanges, a greater degree of design freedom is provided and material costs are reduced. Further, if the flange is clamped, a claiming force is not exerted on the reference hole, thereby preventing deformation or displacement of the hole.
