Abstract: A method of imprinting a substrate (180), comprising affixing a flexible stamp (104) carrying an imprinting pattern (106) to a first carrier (102) comprising an array of apertures (112) which, by gas pressure, either pull the flexible stamp towards the first carrier or push it away; pushing it to a second carrier (170) carrying a substrate (180) with a resist layer (182), leaving a gap (190) for creating a controllable contact area between the flexible stamp and the substrate and space (196) between the first carrier and the flexible stamp; progressively pushing areas of the flexible stamp into the resist layer to imprint it; developing the resist layer; and progressively releasing the flexible stamp by applying suction through successive apertures whilst controlling the inward flow of gas to the space (196) through the apertures that are not yet under suction in order to maintain the space (196) there above ambient but below a predetermined maximum pressure.

Abstract: A mold for production of cast parts, having two mold parts in the form of mold plates, which mold parts arc movable with respect to each other from an open position into a closed position, wherein the mold parts in their closed position define a mold cavity which may be filled with liquid casting compound and in their open position enable removal of a cast part which has solidified by at least partial cooling, and are lockable in their closed position by a locking device which joining the two mold parts so as to be releasable, and which mold parts may also be swung, wherewith in the closed position the locking device produces the locking of the mold plates with the stipulation that the locking pressure is maintained. The locking device has an energy storage means with a gas pressure spring for maintaining the closing pressure which presses the mold plates together after they have initially been pressed together.

Abstract: A molding machine comprises a mold composed of lower and upper mold sections. A recess is defined in the lower mold section to receive a lead frame or other objects. The lead frame is sandwiched between the upper and lower mold sections. A mold cavity is defined in the lower mold section below the recess so as to receive a thermosetting resin or encapsulant. A gasket groove is defined adjacent to the mold cavity to receive a gasket. The gasket is subject to plastic deformation upon application of force. An oil chamber is communicated with the gasket groove and contains hydraulic oil. The hydraulic oil is pressurized to urge the gasket against the lead frame. As a result, the gasket is so deformed as to closely contact the surface of the lead frame and seal the mold cavity. The hydraulic oil is preferably mixed with thermoplastic resin in powder form.

Abstract: An oil circuit in which a meter-in circuit and a differential circuit are combined is disposed. Oil is supplied from a variable capacity pump in order to make a mold opening/closing control apparatus operate. A position instruction signal obtained by integrating a velocity instruction signal and a positional deviation of the displacement of the mold opening/closing control apparatus are obtained. A flow-rate instruction signal is set by the positional deviation. Then, a differential switching determining section receives the positional deviation and determines differential switching, following which a differential change-over valve switches between the meter-in circuit and the differential circuit. With a gain switching section connected to the differential switching determining section, the gain switching section switches between a pump gain for the meter-in circuit and a pump gain for the differential circuit. The above variable capacity pump is controlled by the switched pump gain. A fixed capacity pump may be connected to the variable capacity pump and used. In such a case, switching between un-load and on-load is performed in response the reception of a flow-rate instruction signal from the gain switching section.
