An input device includes a first part and a second part configured to move relative to each other according to an input operation, a magnetic viscous fluid whose viscosity changes according to a magnetic field, and a magnetic-field generator that generates the magnetic field applied to the magnetic viscous fluid. The second part includes a first surface and a second surface that are arranged in a direction orthogonal to a direction of relative movement between the first part and the second part. Gaps are formed between the first surface and the first part and between the second surface and the first part, and the magnetic viscous fluid is present in at least a part of the gaps.

A damping structure which dispenses of the connection of a resistor used for a conventional damping structure and undergoes diverse molding processings with a simpler structure, and a laminate damping base material constituting such a damping structure. A laminate damping base material made of a piezoelectric ceramic material or piezoelectric polymer material and a conductive fiber-reinforced plastic (FRP) composition is prepared. One to a plurality of this base material are stacked to constitute a first damping structure. A second damping structure is constituted by stacking at least a layer of piezoelectric polymer film or piezoelectric ceramic thin film between a multilayer laminate that is a laminate of conductive laminate FRP base materials.

The present invention provides a method for sorting post-consumed bottles exactly and efficiently and an apparatus for carrying out the method. The sorting apparatus comprises a supply section, a separating section, a detecting section comprising a first image pickup camera for detecting the size and contour of each post-consumed bottle and a second image pickup camera for high speed detection of color by a defined image pickup utilizing data from the first image pickup camera, a sorting section for sorting and discharging only post-consumed bottles already classified to sorting containers preliminarily placed in accordance with data received from the detecting section, and a control section for controlling a series of operations timely. Since the scope of the image pickup for detecting color of the post-consumed bottles is defined in accordance with the data from the detecting section, picture processing at a high speed is achieved resulting in remarkable sorting performance.

To apply exactly a variety of operating patterns to an automatic transfer apparatus for use in a forging press, an arrangement is proposed comprising: intermediate frames each mounted on an external frame so as to move freely up and down; a clamp frame mounted on the intermediate frame so as to move freely in a lateral direction; a pair of beams mounted on the clamp frame so as to open and close freely; servo motors for performing upward and downward motion, lateral motion and opening-and-closing motion; and drive control equipment. The operation patters are inputted to a microcomputer for picture processing and displayed. Accordingly, the driving operations are exactly controlled by pulse signals and feedback pulses of the servo motors. The arrangement is applicable to various types of motions. Feed motion being of the longest stroke is linear and therefore positioning becomes accurate. The construction is advantageous in accomplishing a small-sized and light-weight automatic transfer apparatus.
