Patent CA-2071112-A1 (CA)
Title: Rate mode hand controller with force reflection
Inventor: HEGG JEFF
IPC: B25J9/16
Filed: 1992-06-12
Abstract: ABSTRACT OF THE DISCLOSURE      A rate mode robotic control system in which displacement of a hand-control element from a null position generates a robotic control signal to command acceleration and/or velocity of a controlled element.  A force generator urges the hand-control element to the null position with a force proportional to the displacement of the hand-control element from the null position.  A reflected force feedback signal increases or decreases the force urging the hand-control to the null position as a function of the resistance encountered by the controlled element.

IPC: A63B69/38
Filed: 1992-06-26
Abstract: ABSTRACT         An apparatus for developing strength and skill in striking a ball in sports such as golf, tennis, squash, raquetball, table tennis, baseball, cricket and the like where an increase of strength, hand-eye coordination, muscle memory, and/or concentration is advantageous to the participant. The apparatus provides at least two strings which pass through, or on, a system of anchor members or brackets, such as pulleys, slides, orifices or arcuate shapes. and a means of providing a resisting force, such as a set of weights of spring loaded devices. The distal end from the handle of the club, racket or other ball striking device is attached to the strings and the ball striking device is held and swung by the user. The strings run through the anchor members or brackets in such a manner that the forces applied to the ball striking device have both vertical and horizontal components of force throughout the swing which give beneficial exercise, muscle memory and coordination, and the ability to concentrate and focus when the ball striking device is moved slowly through the swing motion.

Title: Fiber-optic gyroscope
Inventor: NISHIURA YOZO
IPC: G01C19/72
Filed: 1992-07-09
Abstract: A fibre-optic gyroscope is provided herein for measuring an angular velocity of a fibre coil by propagating light beams clockwise and counterclockwise in a specified fibre coil, by detecting an intensity of an interference beam, and calculating a phase difference between a clockwise propagated beam and a counterclockwise propagated beam. The fibre-optic gyroscope includes a light source for emitting a quasi-monochromatic light beam. A photodetector is provided for detecting an intensity of the interference beam. A defined plurality of fibre paths are interconnected in a specific defined manner, with a polarizer, a first depolarizer and a second depolarizer as well as a first coupler and a second coupler being provided in specified fibre paths. The depolarizers are constructed by coupling a polarization-maintaining fibre to the front end and/or the rear end of the polarizer at a 45° inclin-ation angle between principal axes of the polarizer and the polarization-maintaining fibre. The polarization-maintaining fibre has a difference of optical paths between the quasi-monochromatic beam and the interference beam with different principal axes being longer than a coherent length of the light source.

Filed: 1992-09-14
Abstract: A method for controlling the energization of a thermal printing heating element by a succession of current impulses (I) separated according to a printing raster is described.  The current impulses (I) upon exceeding a pre-given energy content effect a printing event and in the case of falling below this energy content effect a preheating. At each raster time point (t1) the printing requirement is ascertained for a predetermined number of yet to follow raster time points (t2, t3) and for raster time points (t2, t1) without printing requirements and lying in advance of a raster time point (t3) with a printing requirement the current impulses (I1, I2) are progressively increased.  Through the use of this method a thermal printer with a high printing speed is achieved.

Abstract: An antenna employs the back radiation of a crossed-dipole to illuminate a parabolic cylindrical reflector. The crossed dipole is supported by a feed network mast which simplifies the feed network and eliminates the need for other supporting structure and its electrical blockage.  To form an antenna system having omni-directional radiation coverage, four of these antennas are located at the four quadrants, each covering one quadrant in the azimuth direction. The RF signal is fed through a single pole four throw switch to the selected antenna to be radiated to the desired direction.

Title: Process and device for producing metal strip and laminates
Inventor: FEICHTINGER HEINRICH K
IPC: B22D11/06
Filed: 1992-05-18
Abstract: ABSTRACT OF THE DISCLOSURE      A stream of superheated molten metal is deposited from a container, in a consolidated form by means of a pouring nozzle or separated into drops by a gaseous medium, at a casting point on the inner surface of a wound strip or laminate rotating in and together with a mould.  An initially liquid metal film is thus produced to which a fluid coolant, preferably a deep-cooled liquefied gas such as argon or nitrogen, is applied from a cooling nozzle at a cooling station staggered in the direction of rotation in relation to the casting point, by means of which a substantial proportion of the superheating and melting heat of the metal film is largely dissipated by evaporation.  Depending on the residual heat remaining after the cooling cycle, the metal film remains either insulated from the previously applied innermost metal layer, thus producing a strip, or melts with it, thus forming a substantially rotation-symmetrical laminate.

IPC: H05K3/40

Abstract: P0756.PCT     ABSTRACT     In the metal-clad laminate according to the invention it is assumed that the requirements concerning the mechanical strength are functionally separated from the circuit connection requirement, so as to be able to bring the circuit connection, particularly for signals, "closer" to the electrotechnical characteri-stics of the chips. For this purpose and without taking account of the mechani-cal strength of the substrate, the layout miniaturization is optimized. In placeof a circuit board (MCM), a laminate which can be built up to a circuit board is produced. The inventive laminate comprises an extremely thin foil with a plurality of extremely small holes simultaneously etched in an etching process. The hole diameter can be reduced by almost an order of magnitude (up to 20µm), which e.g. permits a sub-100 µm technology. Such a laminate is not used as a mechanical support and is only provided for signal guidance. The effect of the miniaturization can be seen in the diameter for the plated-through holes. With a hole diameter reduction there is an increase in the current path density, which gives over 10000 plated-through holes per dm2. The drawing shows the compression ratio compared with standard technology.            (Fig. 6g)
