An electric cylinder includes: an outer cylinder including, on one end side, a fixing section; a rod configured to be capable of expanding and contracting in an axis direction from an opening on the one end side of the outer cylinder; a bearing provided on the other end side end and on the inside of the outer cylinder; a rotating shaft supported by the bearing and driven to rotate; a screw mechanism configured to convert a rotational motion of the rotating shaft into a linear motion of the rod and transmit the linear motion; and a distortion detecting unit provided on the outer circumference of the outer cylinder. The outer cylinder includes at least two or more division members that can be divided and combined. The distortion detecting unit is provided in one division member among the two or more division members.

Electric cylinder and electric cylinder system

An electric cylinder system includes: an electric cylinder; and a control section that controls the electric cylinder. The electric cylinder includes: an outer cylinder; a rod configured to be capable of extending and retracting in an axis direction from an opening on one end side of the outer cylinder; a bearing provided on the inside of the outer cylinder; a rotating shaft rotatably supported by the bearing and driven to rotate with driving force of a motor; a screw mechanism that converts a rotary motion of the rotating shaft into a linear motion of the rod and transmits the linear motion; and a load detecting section that detects a load in an axis direction applied to the rod in a position where the load is transmitted from the rod through the screw mechanism. The control section controls the electric cylinder on the basis of a signal from an encoder of the motor and a signal from the load detecting section.

An apparatus is provided for manufacturing liquid-crystal panels with a uniform gap by pressing the entire surface of an empty cell, while any warp or undulation in the empty cell is corrected. The apparatus is characterized by a flat pressure-contacting plate 6 mounted on a horizontally fixed base stand 2, a suction frame 10 disposed movably up and down relative to the base stand 2, the frame 10 having a center opening 12 for accommodating and depressurizing the pressure-contacting plate 6 and an empty cell W, a film 13 for transmitting ultraviolet rays to close the opening 12, and ultraviolet-ray radiation means 17 disposed just above the suction frame.

Apparatus for manufacturing liquid-crystal panels

A press apparatus for use in manufacture of a liquid crystal panel presses upper and lower glass substrates placed between a pressure-exerting plate and a pressure-receiving plate while a seal located around the glass substrates is being heated and melted. The pressure-exerting plate is supported by a pressure-transmitting plate through three load cells. The pressure-transmitting plate presses the pressure-exerting plate against the pressure-receiving plate through the load cells and thereby presses the glass substrates uniformly. When a difference between the detection values of the load cells exceeds a predetermined value, it is determined that the glass substrates are not being pressed uniformly and the pressing operations thus stopped.
