Abstract: In a power unit comprising an engine (13) and an HST (24) which are formed into an integral body, a lubricating oil for use in the engine and an operating oil of the HST (24) are commonized. After being cooled, the common oil is fed from the side of the engine (13) to the HST (24). Such arrangement suppresses the drop in viscosity of the common oil and prevents the drop in efficiency and the occurrence of seizing on the side of the HST (24).

Abstract: An HMT apparatus (T) is mounted on a vehicle (A). In the HMT apparatus (T), input rotational force from an engine (13) is once divided into two systems which are then transmitted by an MT device (23) and by an HST device (24) respectively and are re-synthesized for transfer toward wheels (12) and (16). The HMT apparatus (T) is disposed on the vehicle-body right side of the engine (13) which is sideways-mounted on a vehicle body (1), and its input and output shafts (25) and (26) are disposed in parallel with a crank shaft (13a) of the engine (13) and are disposed to run parallel with each other. The input shaft (25) is coupled directly to the crank shaft (13a) and an input gear (27) of the MT device (23) is mounted on the input shaft (25), and a hydraulic piston pump (30) of the HST device (24) is connected to the right side end of the input shaft (25).

Abstract: A rosin emulsion sizing agent for paper making comprising a rosin substance, a dispersing agent and water, the rosin substance comprising (a) a rosin or a fortified rosin and (b) a rosin ester or a fortified rosin ester, the dispersing agent comprising a (meth)acrylamide copolymer obtained by polymerizing a polymerizable monomer mixture containing (A) 70 to 95% by mole of (meth)acrylamide, (B) 0.5 to 10% by mole of a sulfo (salt) group-containing monomer or a phosphoric acid (salt) group-containing monomer and (C) 1 to 20% by mole of a hydrophobic monomer, and a method for paper sizing using the same.

Abstract: A positioning apparatus can perform high-accuracy positioning in a short time without a Curvic (trademark) or positioning coupling. With provision of a hydraulic motor having a rotary shaft fixed to a turret head and a hollow type rotary encoder for detecting the angle of rotation of the rotary shaft, rotation of the hydraulic motor is controlled by a controller via a control valve. Locking of the rotary shaft is performed by a rebound force of a spring provided in a hydraulic cylinder by pressing a pad provided at a tip portion of a rod against a disk. Unlocking of the rotary shaft is performed by supplying a hydraulic fluid into a cylinder chamber by switching a directional control valve.

Abstract: The sizing agent of the invention contains a rosin substance, a dispersant and water in which an amphoteric, anionic or cationic copolymer is used as the dispersant, the copolymer being prepared by copolymerizing (A) a vinyl carboxylate as an essential monomer and (B) an anionic unsaturated monomer and/or (C) a cationic unsaturated monomer.

Abstract: The present invention relates to a ketene dimer sizing agent for paper making comprising a dispersed phase containing a ketene dimer and an aqueous continuous phase containing a dispersing agent, characterized by containing polymeric aluminum hydroxide and/or polymeric aluminum chloride. The ketene dimer sizing agent for paper making of the present invention can be preferably used in, for instance, a neutral paper making and the like since it is excellent in sizing effect and storage stability.
