摘要： In a drawing device for presses with a mechanically driven drawing ram (24) and with a sheet metal holder (5) exerting its holding force, acting on the metal sheet (27) and counteracting the drawing direction, by way of a pressure plate (7) by means of a die cushion piston (10), supporting the pressure plate and being under the effect of a pressure medium, in a fixed die cushion cylinder (12), the objective consists in avoiding, or at least reducing, the noise-generating impact shock upon impingement of the drawing ram (24) on the sheet metal holder (5) with the metal sheet (27) lying thereon.This objective has been attained by mounting to the pressure plate (7) a piston (9) with a working surface exposable in the drawing direction, and by providing a control means (22, 23) operating in dependence on the ram stroke, this control means making it possible, before placing the drawing ram (24) on the sheet metal holder (5), to accelerate the latter, by exposing the working surface to a pressure medium, toward a movement in the drawing direction, the velocity of this movement being equal to or not much lower than the velocity of the drawing ram (24) upon impingement on the sheet metal holder (5).

摘要： The invention relates to an encapsulated piezoelectric resonator device comprising an oscillating member having a quartz member and a frame integral with and surrounding the quartz member, the frame having two connecting faces, electrodes on the quartz member, and two cover members, each having a central depression defining a frame provided with a connecting face, each connecting face of the oscillating member being bonded with the connecting face of the cover member for sandwiching the oscillating member between the cover members.The invention also relates to a method for manufacturing such an encapsulated piezoelectric resonator device comprising the steps of machining a quartz plate by photolithography for making at least one oscillating member, forming electrodes on the quartz member, making at least two cover members having central depressions defining their peripheral frames and bonding the oscillating member with two cover members by their frames.
