Title: Fuel efficient methods for satellite stationkeeping and momentum dumping
Inventor: HO YIU-HUNG M
IPC: B64G1/26
Filed: 1998-12-08
Abstract: Satellite stationkeeping and momentum-dumping methods are facilitated by the use of diagonally-arranged thruster pairs which are positioned on a selected one of a nadir and an antinadir satellite face. A first one of the thruster pairs is directed so that its thruster forces are spaced by moment arms from the satellite's center of mass. Firings of this thruster pair are separated by a momentum-dumping right ascension difference that is chosen to enhance momentum authority. These firings generate momentum-dumping torques and contribute to stationkeeping velocity changes. A second one of the thruster pairs is directed so that its thruster forces substantially pass through the center of mass. Firings of this thruster pair are separated by a stationkeeping right ascension difference chosen to minimize fuel consumption while providing a major portion of stationkeeping velocity changes.

IPC: G01N21/39
Filed: 1998-04-08
Abstract: The method for analyzing an impurity in a gas comprises the steps of: introducing a gas with an impurity into a first cell (2); introducing a gas with no impurity into a second cell (3); maintaining identical pressures in the first and second cells; irradiating a light from a light irradiating means (1); splitting the light by a splitting means (4) in order to pass a first beam trough the first cell and to pass a second beam through the second cell; measuring the intensity of the light passing through the first cell by a first measuring means (5) and the intensity of the light passing through the second cell by a second measuring means (6); and determining an absorption spectrum of the impurity in the gas based on the difference between measuring data from the first measuring means and measuring data from the second measuring means.

Title: Stereo slide mount and masking-amount guide device
Inventor: INABA MINORU
IPC: G03B21/64
Filed: 1996-03-11
Abstract: A stereo slide mount is divided into a base frame  (21)  and  a  cover  frame  (22)  in  order  to facilitate  the  operation  for  mounting  the  stereo slide and to improve correctness.  The size of the windows of the base frame is equal to the size of the pictures of the films, and pins (25) are provided at four  corners   of   the  windows   to   engage  with perforations of the film.  The cover frame  (22)  has holes  (26)  that correspond to the pins  (25)  and can be fitted to the base frame.  The cover frames  (22) are prepared in plural kinds  (#0, #1,  ---)  in which the width  (C1)  between the windows is equal to the width between the windows in the base frame, and the width (W) of the window decreases stepwisely. Plural kinds of masking-amount guide devices (31) having the same size of windows as that of the cover frames and having a collimation pattern at the same position on the  right  and  left  windows,  are successively  and temporarily fitted to the base frame  (21),  and the image of the stereo slide films is observed using a stereo slide viewer.  The films are mounted on the base frame by using a cover frame of the same number as the number (#) of the masking-amount guide device (31) with which the sense of distance to the subject in a close-range view is in agreement with the sense of distance to the collimation pattern (35). There is thus obtained a stereo image with the parallax being suitably corrected.

Title: Oil containing lipid vesicles with marine applications
Inventor: WRIGHT D CRAIG
IPC: A23K1/18
Filed: 1997-04-30
Abstract: Disclosed is a new class of lipid vesicles, liposoils, which have high oil content, low water content, and protein. The liposoils are made using a combination of a surfactant and either dried egg yolk or dried whole egg as the wall material, oil, and an aqueous diluent. Unlike most lipid vesicles, the liposoils can be made with an aqueous diluent having high salinity; in fact, sea water is a preferred aqueous diluent. Liposoils have particular applicability as a food for marine environments, such as a food source for filter feeders such as oysters. Methods of making the liposoils are also disclosed.

Patent CA-2271554-A1 (CA)
Inventor: BABA MITSUO
IPC: H04L25/08
Filed: 1999-05-10
Abstract: Duty measuring circuitry of the present invention includes a pulse detecting circuit for detecting at least one of a convex pulse width and a concave pulse width included in an input data signal. A duty decision circuit determines whether or not the convex pulse width or the concave pulse width detected is smaller than a preselected value. If the detected pulse width is smaller than the preselected, the duty decision circuit determines that the pulse width is valid, and feeds it to an averaging circuit.      The circuitry obviates the need for an exclusive fixed pattern, a.g., ONEs and ZEROS alternating with each other customarily used for the measurement of a duty. In addition, the circuitry is capable of accurately measuring a duty even with a random pattern based on RZ (Return-to-Zero) code or NRZ (Non-Return-to-Zero) code.
