    • The injection apparatus, which injects a molding material into a mold by operating an injection cylinder and fills the mold with the molding material, includes a plurality of actuating mechanisms that is connected to the injection cylinder. Each actuating mechanism includes an actuating cylinder that supplies an incompressible fluid to the injection cylinder, and a drive part that drives a piston of the actuating cylinder. In a low-speed step and a high-speed step for injecting the molding material, the piston of each actuating cylinder is driven forward, and hydraulic oil is supplied to the injection cylinder. In a pressure-increasing step, the pistons of the actuating cylinders are driven forward, and hydraulic oil is supplied to the injection cylinder. As the injection apparatus includes a plurality of actuating mechanisms, the speed and pressure of the injection cylinder can be increased without requiring high performance from the drive parts.
    • 注射装置通过操作注射圆筒并且用模制材料填充模具将模制材料注射到模具中,包括连接到注射圆筒的多个致动机构。 每个致动机构包括致动气缸,其将不可压缩流体供应到注射缸,以及驱动部件,其驱动致动缸的活塞。 在用于注射成型材料的低速步骤和高速步骤中,每个致动缸的活塞被向前驱动,并且液压油被供应到注射缸。 在增压步骤中,致动气缸的活塞被向前驱动,液压油被供给到注射缸。 由于注射装置包括多个致动机构,所以可以增加注射缸的速度和压力,而不需要来自驱动部件的高性能。

    • The invention provides an axial flow machine that effectively reduces the unstable hydrodynamic force induced by leakage flow and thereby prevents unstable vibrations.A steam turbine comprises: a ring-shaped cover 6 connected to the outer circumferential side of a rotor blade row 4; and a ring-shaped concave section 12 provided on an inner circumferential surface 8 of a casing 1 for housing the cover 6. A narrow passage 15 is formed between an outer circumferential surface 13 of the cover 6 and a bottom surface 14 of the concave section 12. A narrow inflow passage 18 is formed between an upstream lateral surface 16 of the cover 6 and an upstream lateral surface 17 of the concave section 12. A narrow outflow passage 21 is formed between a downstream lateral surface 19 of the cover 6 and a downstream lateral surface 20 of the concave section 12. Between the narrow inflow passage 18 and the narrow passage 15 lies an expanded inflow passage 22. The expanded inflow passage 22 has a substantially uniform structure in a circumferential direction and is formed such that it is located on the more outer circumferential side than the bottom surface 20 of the concave section 12 and such that it is located upstream side in terms of the rotor's axial direction with respect to the upstream lateral surface 17 of the concave section 12.
