    摘要: A swash-plate plunger-type hydraulic device has a cylinder block with a plurality of plungers slidably fitted in cylinder bores, a swash plate confronting one end of the cylinder block, and a distribution valve plate slidably held against the other end of the cylinder block. The cylinder block has an even number of circularly arrayed connecting ports communicating with the cylinder bores and opening at the other end thereof. The distribution valve plate has inlet and outlet ports. The cylinder block is rotatable through an angular displacement .theta.1 in which the hydraulic pressure in one connecting port between the inlet and outlet ports increases from a lower pressure to a higher pressure, through an angular displacement .theta.2 in which the hydraulic pressure in one connecting port between the inlet and output ports decreases from the higher pressure to the lower pressure, and through an angular displacement .theta.3 from a position where the hydraulic pressure starts to increase to a position where the hydraulic pressure starts to decrease. The inlet and outlet ports are defined such that the angular displacements .theta.1, .theta.2, .theta.3 are expressed by:.theta.1=.theta.2 and .theta.3=180.degree..

    摘要: A belt type cast sheet continuous caster of the type comprises a pair of opposed circulatorily movable belts, a pair of opposed side plates arranged along opposite side edge portions of the movable belts, coolers which each have numerous water feed openings and water discharge openings opened to the movable belt and are arranged behind the respective movable belts, and movable partition plates which are placed in respective cooling headers and each connected to driving means for moving the partition plates in a width direction of a cast sheet. A casting space is defined by the movable belt and the side plates. Melt leakage at sliding portions between mold short side plates and the metal belts in a belt type cast sheet continuous caster comprising the metal belts and the mold short side plates arranged along side edge portions of the metal belts and cooleres, which each have numerous water fed openings and water discharge openings opened to the metal belt and are arranged behind the respective metal belts, is prevented by controlling gaps between the metal belts and the mold short side plates through varying a pushing force of the metal belts to the mold short side plates.

    摘要: In a small particle detection system for use in detecting small particles, which float in a gas, by utilizing the light scattering effect thereof, a detecting cell is disposed in an external optical resonator which is adapted to resonate with the output light from a laser oscillator. When the detecting cell is disposed in the laser oscillating optical resonator, the position is selectively determined; the former is set in the position in the latter in which the diameter of a laser beam is minimal.

    摘要: An apparatus for continuously producing polyester comprises three single reactors, i.e. a single esterification reactor (first reactor), a single initial polymerization reactor (second reactor) and a single final polymerization reactor (third reactor or final polymerizer), where at least one of the first reactor and the second reactor is free from an external stirring power source, or the third reactor is a horizontal, one-shaft-type, low speed rotation type reactor. Necessary number of reactors for the esterification and polycondensation reactions can be a minimum and necessary stirring power consumption for the reaction can be a minimum, and thus polyester polymers of good quality can be efficiently produced at a minimum energy cost in a necessary minimum reactor structure.
