IPC: B31C1/06
Filed: 1982-09-07
Abstract: A method and an apparatus for manufacturing a tin-like container comprising a sleeve formed body or jacket (1) and at least one end closure (2, 3), in which the jacket (1) and the end closure or the end closures (2, 3) at the interior side of the container has a layer (5) of a constant heat weldable, high frequence weldable or ultrazonic weldable material, and in which the container is closed under sealed condition in that the end closure (2, 3) is formed with an edge flange extending all around the end closure and is introduced in the jacket (1) and is welded thereto. The introduction of the end closure (2, 3) in the jacket (1) is made by means of a press piston (14) having a press cone (15) which is formed with an expandable means (15d; 29). In the non-expandive condition the expandable means (15d; 29) is located inside of the cone surface, and it is adapted to become expanded before or at the same time as being welded to the innersurface of the container, whereby a resilient additional pressure line is obtained round the entire weld surface and along at least some part of the height of the weld surface.

Title: Linear motor supporting apparatus for vehicles
Inventor: KOBAYASHI NOBORU
IPC: B60L13/03
Filed: 1989-11-29
Granted: 1994-06-28
Abstract: ABSTRACT    The linear motor supporting apparatuses are mounted to the front and rear portion of each bogie of a vehicle to maintain the small distance between an on-board coil and a ground stator, the on-board coil and the ground stator together constituting the linear-induction motor.          The linear motor supporting apparatus incorporates a servo device which regulates the vertical position of the on-board coil according to the contour of the ground stator to keep the on-board-coil-to-ground-stator distance to a small predetermined value.  The servo device consists of a valve body, a valve box, and a servo device body.  The valve body is secured to a sensor member, which runs on and is kept in contact with the ground stator.  The valve box is secured to the on-board coil.  The servo device body is mounted through a spring to the bogie.  The ground stator has some laying errors and there are variations in its height.  When the sensor member during operation is lifted up due to height variations in the ground stator, the valve body moves up causing, through hydraulic pressure, the valve box to follow its upward motion.  This in turn causes the on-board coil, which is integral with the valve box, to move up thus keeping the distance between the on-board coil and the ground stator constant.

Abstract: A microdrive apparatus of a micromanipulator ac-cording to the present invention is such that a piezo-electric/electrostrictive element having an inertial member mounted at its tip is attached to a moving member supported on a frictional surface of a support member, and a miniature instrument for manipulation is attached to the moving member.  By applying an electric field to the piezoelectric/electrostrictive element, the minia-ture instrument for manipulation is controlled for fine movement by utilizing this kinetic energy, the inertial effect of the inertial member, and the reaction force acting upon the moving member.  In addition, the minia-ture instrument for manipulation can be controlled to assume a predetermined position and predetermined atti-tude by a micropositioning device having an articulated portion in which an inertial member is attached to an arm via a piezoelectric/electrostrictive element.

Abstract: APERTURE SYNTHESIZED RADIOMETER                USING DIGITAL BEAMFORMING TECHNIQUES                               ABSTRACT A digital aperture synthesized radiometer (10) for synthesizing and imaging an scene. A plurality of antenna arrays (12) receive radiation emitted or reflected from an scene, and an analog to digital converter (16) converts received radiation into digitized signals. A digital beamformer (18) synthesizes the digitized signals to pro-vide an image corresponding to the scene. The digital beamformer (18) comprises individual digital beamformers which generate a set of fanbeam signals (13) for each array. The beamformers (18) provide for cross track imaging of the scene. A digital interferometer (20) correlates corresponding pairs of fanbeam signals (13) from the two sets of fanbeam signals to produce a chirp signal for each pair. A matched filter (22) processes the chirp signals to transform each chirp signal into a corresponding image point of the scene. This provides for along track imaging of the scene. The beamformers (18) include an amplitude weighting and data turning circuit (32) to re-duce fanbeam signal sidelobe levels and eliminate alternate mainlobes from the digi-tized radiation signals to reduce mainlobe widening. A fast Fourier transform circuit (34) in the beamformers (18) generally comprises a decimation-in-time algorithm im-plemented by means of a plurality of parallel and cascaded butterfly computation cir-cuits. Image processing methods for achieving digital radiometry are also disclosed.

Granted: 1994-04-26
Abstract: RANDOM-ACCESS DIGITALLY-TUNED COHERENT OPTICAL RECEIVER Abstract A selectively tunable coherent optical receiver includes a tunable laser for producing a selectable local oscillator frequency for receiving any one of a group of received optical channel signals. The tunable laser is controlled by a feedback loop and a digital processor that stores values of laser bias current. The arrangement produces an exact local oscillator frequency for operating with any one of the group of selectable received channel signals which are spaced over a range of optical carrier frequencies. This receiver avoids frequency sticking and very long pull-in time and determines when there is a missing channel or missing channels.

Title: Voltage generator with voltage multiplier
Inventor: ISHII TAKAAKI
IPC: H02M3/07
Filed: 1990-04-17
Granted: 1996-01-09
Abstract: This invention discloses a voltage generator circuit having a voltage regulator and a voltage generator for supplying voltage to a load. The voltage regulator is powered by a power source which sup-plies a first voltage level and the voltage regulator provides a regu-lated output at a second voltage level lower than the first voltage level. The voltage generator receives power from the regulated out-put and provides a multiplied output having a third voltage level. Therefore, any level of voltage between the first voltage level and the third voltage level is available to the load circuit. Since the voltage regulator supplies the voltage generator with power at a regulated level, the voltage level applied to the multiplier may be adjusted for conserving power.
