摘要:
An oil-cooled type screw compressor capable of improving the oil separating efficiency is provided. The oil-cooled type screw compressor includes an outer casing 21 which encloses at least a bearing portion on a discharge port 12 side of a compressor body 1 in an isolated state from a suction port 11, an oil separating element 22 which comprises an inside portion 22A and an outside portion 22B partitioned from each other by an annular partition plate 26 and which bisects the inside space of the outer casing into a space 27 on the compressor body side and a space 28 on the side opposite to the compressor body, a first discharge pipe 23 which conducts a compressed gas discharged together with oil from the discharge port 12 to the inside portion 22A, a shielding plate 24 for isolating the inside portion 22A from the compressor body-side space 27, and a second discharge pipe 25 extending through both the oil separating element 22 and the portion of the casing 21 which covers the space 28 on the side opposite to the compressor body, to conduct the compressed gas which has entered the compressor body-side space 27 from the opposite-side space 28 to the exterior.

A perforated soundproof structure is formed by oppositely arranging an external plate 1 and an internal plate 2 having a number of through-holes 2a. The board thickness, hole diameter and open area ratio of the internal plate 2 are set to satisfy design conditions to give rise to a viscous effect in the air passing through the through-holes 2a, and the design conditions are set so that the frequency bandwidth to attain an absorption coefficient of 0.3 or more is 10% or more of the resonance frequency.

Provided is an industrial robot system which enables a reduction in an installation/adjustment period, and an increase in a no-error continuous operation period, and includes an action planning section (4) for temporary halts, an error-inducing-task restraining section (5), a section (6) for teaching task, an operation mastering section (7), a hand library (8), an optimum-task-operation generating section (11), a specific task library (9), an error-recovery-task teaching section (12), an error recovery library (10), a finger-eye-camera measurement section (32), a three-dimensional recognition section (33), a controller (30), a manipulator (31), and a universal hand contained in a manipulation device group (34).
摘要:
Engine noise of a construction machine is effectively reduced without reducing cooling performance and with an increase in the height of a body cover kept minimum. To achieve the above, an air-intake opening portion (10) and an air discharge opening portion (11) are arranged in a body cover (8) of an upper rotating body (1), and a cooling fan (5) in an engine room covered by the body cover (8) is driven, taking cooling air in from the air-intake opening portion (10) to cool a heat exchanger (7) in the body cover (8) and discharging the air from the air discharge opening portion (11). The air-intake opening portion (10) is laterally offset from a position facing to a ventilation surface of the heat exchanger (7). Alternatively, plural air-intake opening portions are located in a scattered manner such that the plural air-intake opening portions include the offset air-intake opening portion offset from the ventilation surface of the heat exchanger (7).

摘要:
A phase line tilt calculating unit (actual measurement) receives phase characteristics Pa(f) and Pb(f) outputted from frequency conversion units, and calculates phase difference characteristics of actual measurement based on a phase difference on each frequency component between the phase characteristics. A phase line tilt calculating unit (model) calculates phase difference characteristics between a transfer function Ga(f) and a transfer function Gb(f) calculated by a transfer function calculating unit, and outputs the calculated phase difference characteristics to a search unit. The search unit fits a variable k and determines a variable kopt (optimum solution) in which a tilt g(k) and a tilt gexp substantially match each other. The variable kopt is an index indicating a degree of arterial sclerosis of a subject.
