Title: Method and apparatus for compressing a light pulse
Inventor: CHANG DAVID B
IPC: H01S3/00
Filed: 1993-02-08
Abstract: METHOD AND APPARATUS FOR COMPRESSING A LIGHT PULSE     ABSTRACT OF THE DISCLOSURE This invention discloses a method and apparatus for shortening the length of a pulse of light.  Generally, the method entails altering the index of refraction of an optical medium (14) through which the pulse of light is traveling at an area of the medium (14) where the front end of the pulse of light is located, such that the front end of the pulse of light travels slower than the back end, thus enabling the back end to catch up with the front end in order to shorten the length of the pulse.   To accomplish this, it is proposed to generate an electric field across the optical medium (14) by a charge carrying medium  (12)  positioned relative to the optical medium (14), such that the index of refraction is altered by the electro-optic effect.   In addition,  it is possible to alter the index of refraction of the optical medium (14) by   surrounding  the  optical  medium   (14)   with   a piezoelectric material (20) and applying an electric field to  the  piezoelectric  material  (20)  such  that  the piezoelectric material (20) compresses the optical medium (14), thus altering the index of refraction.

Title: Multi layer plastic product, method of manufacturing same, and co-extruder
Inventor: TAKEDA ISAMU
IPC: B29C48/10
Filed: 1993-08-30
Abstract: ABSTRACT OF THE DISCLOSURE The wall of a plastic product is made a laminated structure formed by colored resin layers and transparent resin layers. A transparent window is formed at part of the circumference of the wall. The window is formed by removing the colored resin layer at the window and filling the removed area with the transparent resin layer. Not all layers are discontinuous at the window area and other area of the wall, but at least one transparent layer is continuous over the whole circumference of the wall, thereby preventing the strength of the wall from being lowered at the window.

Inventor: SCHINDEL DAVID W
IPC: H04R17/00
Filed: 1993-09-07
Abstract: An acoustic transducer which is operable in air up to at least 2MHz is described. A conducting substrate, usually a silicon wafer is etched to provide a selected pattern of micro pits up to about 30µm or more deep. A dielectric film, such as a polyimide film is placed over the etched surface so as to trap air in each individual pit. A conducting upper layer is then superimposed over the dielectric film. When a potential is applied between the substrate and the upper layer the upper layer is driven into motion and enhanced by the vibrations of the air pockets. Alternatively a smooth substrate may be employed in conjunction with an etched dielectric film to achieve the same result. These transducers are useful for non-destructive testing of large structures or for medical diagnostic and therapeutic purposes, without the need for a liquid or gel coupling agent.

Title: Conformable compressed gas storage tank
Inventor: MAHONEY MURRAY W
IPC: F17C1/14
Filed: 1994-01-28
Abstract: ABSTRACT OF THE DISCLOSURE A compressed gas storage tank is fabricated to conform to the dimensions of a convenient and/or available space, such as under the floor of an automobile. The tank comprises a shell having at least a portion fabricated from a superplastically formable material. The superplastic material is bonded to internal structural support members and the remaining portions of the shell. Bonding may be achieved by known methods such as welding and/or diffusion bonding. The internal support members, which need not comprise superplastic material, are positioned internally to provide optimum resistance to gas pressure hoop stresses. In contrast to a thick-walled cylinder, the tank of the present invention may be formed into an irregular shape allowing the tank to fit, for example, under a large fraction of the floor of an automobile by conforming to the available space. The relatively low gas containment efficiency of such an irregular shape is reinforced by the strength and toughness of the shell material, the internal trusses, and stiffening beads or ribs that together constrain the hoop stresses caused by the compressed gas.

Abstract: Orbiting satellites (12) project footprints (30) on the earth. Each footprint (30) is divided into cells (28). Footprints (30) of nearby satellites (12) overlap one another, and the overlap increases as satellites (12) approach a pole from the equator. Positions of all cells (28) generated by all satellites (12) are simulated (36) at numerous points throughout an orbit. Channel sets are assigned to cells (28) within a reference footprint (30a). This assignment is propagated throughout all footprints (30) except for those footprints (30) residing adjacent one side of a seam (16) between orbits (14) where satellites (12) travel in opposing directions. The channel sets are assigned near the seam (16) in response to previously assigned channel sets. Each satellite (12) stores channel set assignments for its cells (28) at various points throughout its orbit. All satellites (12) switch their communication parameters simultaneously in response to the channel set assignments. <IMAGE>

Abstract: A satellite tracking antenna system comprises three or four plane antennas juxtaposed on a single plane.          A first and a second antenna are juxtaposed in an azimuth direction, and a phase difference between signals received by these antennas is detected in order to determine a declination of an antenna unit with respect to the satellite as viewed in the azimuth direction.  The first and a third antenna are juxtaposed in an elevation direction, and a phase difference between signals received by these antennas is detected to determine a declination of the antenna unit with respect to the satellite as viewed in the elevation direction.  The antenna unit is driven so as to reduce these declinations to zero.  Stated differently, values of a sine and a cosine function are extracted which have a phase difference between signals received by a pair of antennas as a parameter, and a tangent value representing the ratio therebetween is calculated and is then inversely converted to provide phase difference information.
