摘要： A workpiece-gripping chuck includes a converting mechanism provided in a body, which converts a driving force from a rotary driving source into a displacement in the axial direction. First and second pistons of the converting mechanism are displaced in the axial direction under a rotary action of a pinion gear. Further, the first and second pistons are displaced in the axial direction, respectively, by supplying a pressure fluid from a first or second port formed in the body. A workpiece may be positioned by means of a pair of gripping members under the driving action of the rotary driving source, and the workpiece is further gripped by the gripping members by applying a pressing force of the pressure fluid in addition to the driving force.

摘要： An ejector functioning as a vacuum generating mechanism is disposed in a main body constituting a vacuum generating unit, and an atmospheric air introducing valve is disposed between the ejector and a vacuum port. The atmospheric air introducing valve is brought into a valve closed state at times when a negative pressure is generated by the ejector under a condition in which a workpiece is held by the negative pressure generated by the ejector, whereby communication between the vacuum port and the atmosphere is blocked. On the other hand, at times when the vacuum is broken, in which the negative pressure state of the vacuum port is released, the atmospheric air introducing valve is brought into a valve open state, whereby the vacuum port communicates with the atmosphere.

摘要： Pressed shape steel, made of a low cost general steel material that is not hardened, forms a frame with long grooves cut therein. Guide rails, made of a specialized steel material that can be subjected to a hardening treatment, are hardened. Thereafter, outer surfaces of the hardened guide rails are ground and the guide rails are integrally joined in the long grooves. Ball-rolling grooves are formed in the guide rails, thereby completing a guide-equipped frame for an actuator. Because the general steel material and the specialized steel material are principally ferrous materials, both exhibiting a Young's modulus at or above 170 GPa with substantially the same coefficient of linear thermal expansion, the frame needn't be increased in size or have a complex internal structure to reinforce the strength of the frame, and the guide rails remain securely retained in the grooves even if the actuator experiences changes in temperature.

摘要： In a flow amount control valve, a rod is inserted through the interior of a housing, and first and second connecting members are connected coaxially to both ends of the rod. A first bellows and a second bellows, each having a bellows portion, are provided on the rod, for preventing leakage of fluid that is introduced into the interior of the housing. In addition, the first bellows and the second bellows are expanded and contracted by displacement of the rod along the axial direction, which is caused by driving an actuator, such that a valve element of the rod approaches and separates with respect to a valve seat, and a gap between the valve element and the valve seat changes so that a flow amount of the fluid is controlled.

摘要： A bent section, which is bent substantially perpendicularly toward a main cylinder body, is formed at one end of a slide table. Further, a pair of ball-rolling grooves, in which a plurality of ball bearings roll, are formed on side surfaces of the slide table opposed to a guide section. A relief groove, which has a width wider than a spacing distance between the ball-rolling grooves and which makes it possible to change the direction of a processing jig when the ball-rolling grooves are processed, is formed at ends of the ball-rolling grooves disposed on a side of the bent section.

摘要： A driver comprises a direction-switching means which switches a rotation direction of a rotary driving source based on a direction instruction signal, a current amplifier/limiter which converts a voltage outputted from the direction-switching means into a corresponding current and which limits the current to a preset reference current IMAX (threshold value), a current sensor which detects the current supplied to the rotary driving source, and a current loop which feeds back a detection signal supplied from the current sensor to an upstream side of the current amplifier/limiter.
