摘要： A cassette loading device of a tape recorder comprises a cassette holder and a pair of link mechanisms which are disposed to the right and to the left of the cassette holder and which operatively connect the cassette holder to the stationary portions of the tape recorder so as to allow the cassette holder to smoothly move between a cassette loading position and a disengaged position giving easy access to the cassette. Each of the pair of link mechanisms includes a first link arm that has one end rotatably mounted on the corresponding stationary portion and an opposite end slidably mounted on the cassette holder for travel within communicating straight and arcuate slot portions; a second link arm has one end rotatably mounted on the cassette holder and an opposite end slidably mounted on the corresponding stationary portion. The first and second link arms of each link mechanism intersect and pivot each other at their intersection. For synchronous movement of one of the link mechanisms with the other, the first link arms and/or second link arms are interconnected for a unitary movement.

摘要： A hydraulic press has closed loop feedback control on a slide, a slide pad and bolster cylinders. Hydraulic cylinders actuating various components of the press are controlled according to ideal position estimates to produce consistent and precise pressing action. A closed loop control consists of an ideal position/pressure value generator, a position/pressure detector and an arithmetic unit comparing the ideal and actual position/pressure values. Using the ideal and actual comparison result, the arithmetic unit produces a control signal to drive a cylinder to a desired position/pressure. The hydraulic press is capable of performing several operations on a workpiece in one press cycle, an improvement over presses requiring several operation steps or die changes. The bolster cylinders augment clamping force, reduce shock, and improve die alignment to produce better results with less wear on press components.

摘要： A plurality of closing cylinder devices are provided between a bolster of a press machine and a bed containing a lower mold of a hydroforming device. An upper mold is attached to a slide of the press machine. The upper mold and lower mold come together to form a cavity having the shape of the exterior of the desired molded product. A closing block, being movable between a first position which is between the slide and a crown of the press machine, and a second position, which avoids the slide, permitting free movement of the slide from the crown to the lower mold. When a material to be hydroformed is place in the lower mold, the upper mold is lowered. The closing block is fit into its first position, thereby restricting movement of the slide in the vertical direction. A inner work pressure is provided by a fluid inside the material to be molded. The closing cylinder devices provide a pressure, based upon the inner work pressure, to maintain the cavity at the desired shape, preventing the upper mold and the lower mold from being separated by the inner work pressure.
