Abstract: A joint for a fluid transport pipe is provided for use in e.g. connecting and communicating a fluid piping device such as a branch pipe or a sluice valve to a through bore defined in a fluid transport pipe. The joint includes a joint body, to be connected to a fluid transport pipe. This joint body has a cylindrical connecting portion projecting therefrom. The cylindrical connecting portion includes a fixed cylindrical member formed integrally with the joint body and a movable cylindrical member fluid-tightly connectable to the fixed cylindrical member to be pivotable three-dimensionally relative thereto.

Abstract: A thixotropic material is charged in a container. The container also holds a movable member which is placed in the thixotropic material so as to stir the thixotropic material. A force transmitting element is connected to the movable member. When an object, the vibration of which is to be controlled, is out of resonance, the amplitude of vibration is so small that the thixotropic material is in a gel state, thus presenting a comparatively large spring constant for the vibration control apparatus. As the excitation frequency is increased towards the resonance range, the amplitude of vibration is increased correspondingly, so that the movable member stirs the thixotropic material to generate stress in the latter, whereby the phase of the thixotropic material is changed from gel to sol. Consequently, the natural frequency of the vibration system, including the object and the vibration control apparatus, is lowered, thus averting resonance.

Abstract: A photocoupler for image recognition is disclosed which comprises a case, a pair of a light emitting diode and a light sensitive transistor, and a cylindrical lens which forms the light emitted from the diode into a linear light image on a surface of an object having printed pattern. After reflected on a surface of the object, the linear light image passes through the cylindrical lens and is received by the light sensitive transistor.

Abstract: A casing of a stacker is provided with an opening and a chamber for disposing a pusher within the casing adjacent to the opening so that the pusher can be removably attached within the stacker. Also provided in the pusher is a slit-shaped inlet connected with an exit of a passageway within a transporter. By removing the pusher from the stacker and attaching same to another stacker having its compartment of different capacity, bill storing capacity may easily be changed. In malfunction of the pusher, it may easily be exchanged with new one for easy maintenance.

Abstract: A magnetic resonance imaging apparatus includes a magnet for generating a static magnetic field, a gradient coil for generating a gradient magnetic field in a measurement space, and a vibration damping means which includes a container and granular material disposed in the container. The vibration damping means is installed with a supporting bolt between the gradient coil and a supporting means. Since the gradient coil is supported at a constant position without any vibration and deformation, the magnetic resonance imaging apparatus generates an accurate image signal without any acoustic noise.

Abstract: A currency stacker is disclosed which a pusher is positioned within a first chamber of a casing. This pusher comprises a base plate, a pusher plate and a link connecting the base plate and pusher plate for traveling the pusher plate from the retracted position within the first chamber to the extended position in a second chamber of the casing toward and away from the base plate. A bill supplied to the first chamber through a slit of the casing is moved by the pusher plate to the second chamber when the pusher plate is moved to the extended position. Disposed within the first chamber is a driver for operating the link to travel the pusher plate between the retracted and extended positions. The driver keeps the pusher in the extended position to prevent unauthorized removal of the bill from the second chamber.

Abstract: A magnetic-resonance imaging apparatus has superconducting magnets for generating a large uniform magnetic field within a predetermined volume. Within that volume, coils for generating magnetic field gradients are supported on a bobbin, enabling an object within the bobbin to be investigated. The coils on the bobbin are subject to forces but are rigidly connected to the bobbin. Therefore, energy is transmitted to the bobbin which can cause the bobbin to vibrate and so generate noise. To dissipate that energy, the coils are attached to tubes, or other hollow members, on the bobbin, which tubes or hollow members contain movable bodies such as particulate material. The energy due to the forces on the coils cause the movable bodies to move and collide, so dissipating the energy and reducing the noise.

Abstract: In a floating type magnetic head support mechanism for a magnetic disk apparatus, a slider carrying a magnetic head floats a small distance above a magnetic disk in accordance with a rotation of the magnetic head to enable a reading/writing of information from/onto the disk by the magnetic head. The slider is coupled to a distal end of a load arm through a gimbal. The coupling portion is located in a common plane parallel with a floating surface of the slider, with the coupling portion including a center of gravity of the slider or being in a parallel plane closer to the floating surface than the center of gravity. The magnetic head support mechanism is so constructed that no rotational moment is applied to a slider during the access operation by the access mechanism.

Abstract: A transducer supporting device having a rigid-structure support member connected to a guide arm, and a flexible-structure support member attached to the rigid-structure support member on the side of a free end of the same. Portions of the rigid-structure and flexible-structure support members connected to each other are constructed so that the shear center of these portions is brought closer to the connection surface.

Abstract: A process for the recovery of rare earth elements from Bayer Process red mud includes the following steps: (a) digesting red mud containing rare earth elements with a dilute acid solution, e.g. sulphur dioxide dissolved in water, to selectively dissolve the rare earth elements while leaving iron in the red mud substantially undissolved; (b) separating the solution obtained from the solid residue and (c) recovering the rare earth elements from the solution.

Abstract: A process is described for the recovery of rare earth elements from a sulphurous acid solution containing them. The rare earth elements can be successfully separated and recovered by solvent extraction from the sulphurous acid solution, being an organo-phosphorus compound as extraction agent. Di-2-ethylhexyl phosphoric acid or 2-ethylhexyl phosphonic acid mono-ethylhexyl ester is preferred as extraction agent.

Abstract: An apparatus for supporting and reciprocating a magnetic head slider above a rotating magnetic disk comprises a carrying arm having a free end, a flexible base connected at one end thereof to the free end of the supporting arm, a pair of flexible fingers extending from the other end of the flexible base parallel to an axis of the carrying arm and defining therebetween a space, a traverse bar connecting two free ends of the fingers, and a flexible tongued member on which the magnetic head slider to be mounted, one end of the tongued member being connected to the traverse bar and the other end thereof extending into the space with gaps between the tongued member and the fingers and the base. A reduced part of a minimum cross-section is provided in each of the fingers. The reduced part is located between the one end of the tongued member and a center between the one end of the tongued member and the other end of the base.

Abstract: The invention designed to improve the precision in determining the position of the magnetic head and to enable more stable maintenance of the gap between the transducer and the recording disk is characterized in that the flange provided to the transducer supporting arm is made lower in height on the rigid arm side than on the magnetic head side.
