Abstract: A travel operation structure of a work vehicle, comprising a pair of left and right side brake pedals disposed on either the left or right of a steering wheel; a hydro static transmission for changing the speed of travel; and a stop operation pedal disposed on the other of the left and right of the steering wheel; wherein the corresponding left or right side brake is applied when one of the pair of left and right side brake pedals is depressed, and when both the left and right side brake pedals are depressed, both the left and right side brakes operate, and travel is stopped; and when the stop operation pedal is depressed, operating oil of the continuously variable speed change device is directed into an oil tank, and the continuously variable speed change device is switched to a neutral stop position for blocking transmission of power to the travel device.

Abstract: A cabin for a work vehicle comprises: a driver's seat positioned within the cabin; cabin frames including at least a transverse frame located in a rear region of the cabin; a roof supported by at least some of the cabin frames; at least one air-conditioning duct located within the roof; an air conditioning unit located rearwardly with respect to a rearward end of a seat portion of the driver's seat and adjacent the transverse frame for conditioning air and for feeding air-conditioned air into the at least one air-conditioning duct.

Abstract: A method for producing uridine diphosphate N-acetylglucosamine comprising culturing osmo-tolerant yeasts in aerobic conditions in a medium having inorganic salt concentration of about 2-8%.

Abstract: A granular to fine-granular dry mix powder (an artificial kidney perfusion component A of uniform composition) for use in the preparation of an artificial kidney perfusion fluid for bicarbonate dialysis and a method of producing the same.A granular to fine-granular Composition A comprising granules each comprised of a plurality of NaCl grains carrying KCl, CaCl.sub.2, MgCl.sub.2 and sodium acetate adhered to the surface of each grain.NaCl, KCl CaCl.sub.2, MgCl.sub.2 and sodium acetate are mixed in the presence of not less than 10 weight parts of water based on 100 weight parts of sodium acetate and the resultant mixture is heated at not less than 50.degree. C. to bring the sodium acetate into a transiently molten state and mixing acetic acid with the same mixture.

Abstract: A moisture-absorbent composition contains 100 parts by weight of thermoplastic resin and 5 to 400 parts by weight of at least one among the group consisting of magnesium sulfate (represented generally by MgSO.sub.4.NH.sub.2 O (O.ltoreq.n.ltoreq.3), aluminum oxide, calcium oxide, silicon oxide, zeolite, barium oxide, and cobalt chloride. A moisture-absorbent molded item is formed of this composition in a shape of a film, a sheet, a plate, a bag, a pellet, or a container. The molded item may be used as a cushion insert, etc. which requires moisture absorption properties. A moisture-absorbent composition and an molded item made of the composition are provided with an indicator function, by specifying the amount of anhydrous cobalt chloride.

Abstract: The invention provides a pasty composition for perfusing artificial kidney systems for dialysis, the composition comprising about 30 to about 70% by weight of solid electrolyte components consisting of NaCl, KCl, CaCl.sub.2, MgCl.sub.2 and CH.sub.3 COONa and about 70 to about 30% by weight of water, and the composition having a viscosity of about 1,000 to about 7,000 cps at 25.degree. C., and also provides a process for preparing a pasty composition for perfusing artificial kidney systems for dialysis, the process comprising the steps of uniformly mixing NaCl, KCl, CaCl.sub.2, MgCl.sub.2 and CH.sub.3 COONa, adding water and finely dividing the mixture.
