Patent CA-2139086-A1 (CA)
Inventor: MATSUMOTO KIYOTO
IPC: G02B6/42
Filed: 1994-12-23
Abstract: A light-receiving structure for waveguide-type optical devices exhibits excellent productivity, is compactly-formed, and permits highly-efficient coupling. A recess is provided in part of the surface of a substrate on which an optical waveguide is formed, and a light-receiving element is mounted on the recess, with its light-receiving face upward. Near the recess is formed in advance an end face of the optical waveguide, so that a light is emitted therefrom. On the other hand, over the substrate is arranged a cover in which a groove is formed in a position opposite to the optical waveguide, and a reflector is formed in a position opposite to the light-receiving element. The light emitted from the optical waveguide is reflected by the reflector and coupled to the light-receiving element. A  through-hole can be bored in the substrate in advance so that the packaging density can be improved by mounting the light-receiving element on the underside of the substrate with the light-receiving face of the light-receiving element being directed toward the through-hole.

Title: Induction regulator valve for rotary compressors
Inventor: KINDL GERHARD
IPC: F04C28/24
Filed: 1995-07-26
Abstract: In order to provide for infinitely variable regulation of the output from a rotary type compressor, in particular a screw-type compressor, an induction regulator valve is incorporated in the induction manifold of the compressor. The closing piece of this induction regulator valve can be adjusted by means of an actuator system.  In order to improve the regulation performance of this system, in particular to reduce its sensitivity when the regulator valve is almost closed, the spring system is formed so that its stiffness varies along the length of its spring path, the stiffness of the spring system being smaller when the induction regulator valve is open than when it is close to the closed position of the closing piece of the induction regulator valve.

Title: Ultrasonic Side-Looker for Rail Head Flaw Detection
Inventor: HAVIRA ROBERT MARK
IPC: G01N29/24
Filed: 1994-03-11
Abstract: An ultrasonic rail flaw detection system and technique are described for the detection of flaws in the sides of rail heads. An ultrasonic transducer (20) is oriented, sized, and located so as to produce an ultrasonic beam (50) within the rail head (48) whereby at least a portion of the beam will intersect a lower side corner independent of the curvature of the rail head running surface and the amount of head wear. The presence of premature reflections or the absence of reflections can be used to detect flaws such as vertical fractures in the rail head. The side-looker is so oriented as to produce a beam in the rail head that lies within 45 degrees to 75 degrees of the normal to the rail surface, and can be located such that its beam and the beams from other ultrasonic transducers do not interfere with each other.

Title: Apparatus and method for replenishing laser dye solution
Inventor: FURUMOTO HORACE W
IPC: H01S3/02
Filed: 1994-07-27
Abstract: In a dye laser system, a porous bed filter (40) is loaded with dye prior to operation of the system. With repeated firings, the dye solution is filtered by the porous bed filter (40) to remove by-products of the laser process. Solute concentration is monitored (52) and dye and additives removed by the filter (40) are replenished by a metering pump (42). Precise temperature control (56) assures consistent filtering of dye by the filter (40) for more consistent color and energy output. To control (48) the metering pump (42), the differential output of a two-channel absorption detector (68, 70) is digitized (76). The digitized signal is loaded into a counter (78) which drives the metering pump (42). The useful lifetime of the dye solution is enhanced by incorporating pH buffers in die solution.

Title: Magnifying glass having a variable focus, variable enlargement ratio and automatic parallax correction
Inventor: OFNER ANTON G
IPC: G02B7/28
Filed: 1995-08-30
Abstract: The invention relates to a magnifying vision aid for use as magnifying spectacles.   The magnifying spectacles in accordance with the invention have an automatic and/ or a manual focusing device, a device for manually altering the magnification factor and a device for automatic parallax compensation corresponding to the current focal lenath.   If, for instance during a vascular surgical operation, an alteration of the working distance is necessary due to the position of the different operation sites, the vision aid in accordance with the invention takes account of this requirement by the possibility of automatic or manual adaptation of the focal length and the automatic adaptation of the parallax angle. An optimum optical configuration, which always corresponds to the action which is being performed, can thus be ensured and a substantially less fatiguing operation than previously can be rendered possible by the selection of the most advantageous ergonomic position.      Furthermore, the vision aid in accordance with the invention offers the possibility of matching the magnification factor to requirements at every selected working distance.
