A system for taking out a molded product that does not require an operator to determine the sucking operation start time for a vacuum sucker by himself/herself by trial and error is provided. A controller includes a time interval measuring section configured to measure a time interval judging from an output from a pressure detector. The time interval measuring section measures a stable time interval since the pressure in a pipe reaches a predetermined pressure until a sucking operation start pressure is detected judging from an output from the pressure detector. The sucking operation start pressure indicates that a suction nozzle starts operation to suck up a molded product hereby the predetermined pressure is maintained. A sucking operation start time determining section of the controller determines a sucking operation start time such that a stable time interval is longer than a bias time interval, concurrently with movement control for a moving mechanism.

According to the present invention, there is provided a pipe forming apparatus for forming a pipe at an installation site. The apparatus includes a former upon which material is wound, and a mold for receiving the former bearing the wound material. An applicator is provided for applying curable liquid within the mold. Advantageously, the pipe is formed at site to provide for efficient formation of a pipeline. A transported ISO container providing the material and curable liquid to the site can produce 800 metres of pipeline section, compared with 60 metres in the prior art, representing a significant increase in efficiency.

A mold for encapsulating an electrical component. The mold includes an encapsulation chamber and an air inlet. The encapsulation chamber is defined by a housing, an open top, and a solid bottom. The housing includes a solid outer wall, a permeable inner wall, and an air chamber between the solid outer wall and the inner wall. The air inlet is configured to introduce a gas into the air chamber. The encapsulation chamber is sized and shaped to receive the electrical component while leaving a gap for the introduction of encapsulant around the electrical component. The encapsulant may be silicone rubber. To remove an encapsulated electrical component, pressurized air may be introduced through the air inlet into the air chamber, passing through the permeable inner wall, separating the outer surface of the encapsulant from the housing, and allowing the combination casting to be removed from the mold.

A method of packaging a flexible toner bag holding toner including placing the toner bag in a reduced pressure bag; removing at least a portion of the air inside the reduced pressure bag; and sealing an opening of the reduced pressure bag to form a reduced pressure bag assembly.

A process for fabricating an optical device includes injecting (301) optical silicone into a mold cavity formed by two or more mutually matching mold-elements, curing (302) the optical silicone contained by the mold cavity, and separating (303) the mold-elements from the optical device constituted by the optical silicone. The reversible elasticity of the optical silicone after the curing phase is utilized in the process so that at least one of the mold-elements has counterdraft which causes a reversible deformation in the optical device when the mold-element is separated from the optical device. As the counterdraft is allowable, the shape of the optical device as well as the dividing joints between the mold-elements can be designed more freely. For example, walls of the mold cavity corresponding to optically active surfaces of the optical device can be arranged to be free from dividing joints between the mold-elements.

A jig includes mold parts that have a contact surface of a cylindrical part of a material to be molded having a shape complying with the inner peripheral surface of the cylindrical par and are arranged in a direction crossing one direction; a bladder having on a side opposite to the contact surfaces of plurality of mold parts relative to the mold parts, capable of accommodating a fluid therein, and expandable/retractable according to a pressure of the accommodated fluid; a joining part that joins the plurality of mold parts and the bladder; and a connection part that connects a one-side mold part and an another side mold part adjacent to the one-side mold part among a plurality of mold parts to each other and restricts an interval between the one-side mold part and the other-side mold part in a direction crossing the one direction with a prescribed range.

Embodiments of the invention provide clip blow-off pulses of pressurized gas to clip dies using pressurized gas diverted from an onboard knife, gate and/or punch cylinder/valve during a reset or idle period of a clipping cycle and may be particularly suitable for rotating platform systems with circumferentially spaced apart respective clipper stations. Packaging systems include at least one clipper assembly with at least one pulse valve in communication with a pressurized gas (e.g., air) supply configured to generate a respective clip blow-off pulse of pressurized gas across a clip die.
