Title: Temporary center system in distributed data base system
Inventor: RYU TADAMITSU
IPC: G06F17/30
Filed: 1990-09-11
Granted: 1997-03-04
Abstract: A distributed data base system is formed by a pluality of terminal units connected in a public network or a private network, each terminal unit stores respectively the real data and a temporary center for storing the one or a plurality of control information among various pieces of control information such as contents corresponding to each real data, keyword or command assigned to data and moreover check information set up for acquiring security is provided as the one of the terminal unit.  A terminal unit utilizing data obtains identification information of termial units storing relevant real data by inputting contents, commands or keyword by making access to the temporary center and reads or extracts the necessary real data through the network from a terminal unit having real data based on such identification information but is capable of restricting users (terminal units) which are allowed to read the open data in accordance with a degree of importance of data.    This temporary center, when it is assigned to the one terminal unit forming a distribute data base system, executes the control by gathering necessary control information from each termnal unit.  This center having control information may be realized also by the one termial unit but a center may be provided individually corresponding to the items of information to be controlled and moreover the structure is also provided so that a center may be stablished and the center may be altered to the other terminal unit from the terminal unit having the function of the center.

Title: Low aberration field emission electron gun
Inventor: GESLEY MARK A
IPC: H01J37/073
Filed: 1992-02-13
Granted: 2000-04-04
Abstract: A field emission source is used in conjunction with a three element asymmetric lens system to provide an electron gun having greater magnitude beam currents focused on a smaller spot size than has been previously possible for intermediate energy beams. The three element asymmetric lens system has a lower spherical aberration than prior art electrostatic guns and a very low chromatic aberration coefficient, enabling precise focusing of beams with large currents and energy spreads. The electron gun produces high current densities in beams focused on small spot areas, despite the relatively large acceptance angle and energy spread of the source beams.

Granted: 1999-01-26
Abstract: A light assembly combined into a unitary structure with a liquid circulation fitting, such as a water return fitting, for use underwater or above water in a pool, tub, spa, fountain, or similar large liquid container. The combination is well suited for use as a combined underwater light and return water fitting in pools,  tubs,  or spas, and especially in above-ground pools, and as a combined ornamental light and fountain jet. The unitary structure eliminates the need for more than one hole in the pool wall and thereby simplifies installation and decreases the chance of leaks. The structure provides for both water and air cooling if the light is installed underwater.  Furthermore, the structure is connectable to water supply lines of various sizes, and includes a directionally adjustable port to control water returning to the pool or container.

Title: Studs and sockets for studded footwear
Inventor: KELLY PAUL ANDREW
IPC: A43B13/26
Filed: 1991-03-27
Granted: 2000-12-26
Abstract: In a stud and socket combination for studded footwear, a moulded plastics socket (1) provides a threaded axial hole (5) bounded byan inner ring (9). A co-axial outer ring (10) is radially separated from the inner ring to leave an annular space (11). A plastics stud moulding (19) comprises an externally threaded sleeve (21)which can be screwed into the socket hole and a co-axial ring (26) which is spaced radially outwards from the sleeve to slide over the inner socket ring (9) and enter the annular space (11) whenthe stud and socket are assembled. Four part-cylindrical webs (29) project axially from the ring (26) into the space (11) and provide four axially-extending locking ribs (28) at 90° intervals which project radially outwards from the ring. On the inner surface of the outer ring (10) of the socket are formed four corresponding formations providing recesses (15) to receive the ribs (28). Each recess is bordered on one side by a lead-in ramp (16) and on the other side by a stop block (17). When the stud is screwed into the socket the projections ride over the ramps in turn, offering increasing resistance to rotation successively, until finally the projections engage the stop blocks (17) to prevent further rotation.

Abstract: A plurality of 2-dimensional images having parallaxes in only the horizontal directions when an object to be displayed  is seen from different positions in the horizontal direction are inputted.  The 2-dimensional image  is divided in the vertical direction into 1-dimensional line images which are long in the horizontal direction.  A phase distribution of  a corresponding hologram  segment  is  calculated from the pixels of the line image.  The calculated phase distribution  is expressed on a hologram forming surface  of a phase expressing section using a display.  A reproduction light is irradiated and converted into an optical wave front and is further enlarged in the vertical direction, thereby displaying a solid image.  The 2-dimensional images are inputted by photographing the object by a plurality of cameras  arranged  in the horizontal direction.  The 2-dimensional images can be also produced by interpolating  calculations  from two 2-dimensional images which were actually photographed.  The 2-dimensional images which are used in the phase calculations are subjected to a process such as enlargement, reduction, or movement of the coordinate position, thereby adjusting the size and position of a solid image.  The phase distribution  is  calculated every RGB components from the 2-dimensional images and the reproduction light is irradiated every color, thereby displaying a color solid image.

Filed: 1994-09-07
Granted: 2000-08-01
Abstract: A method and apparatus is disclosed for measuring motion signals of gyroscopes in downhole instruments used to determine the heading of a borehole. An illustrative embodiment of the invention includes a measuring-while-drilling system which may experience motion even while the drill string is suspended in rotary table slips when the heading of the drill string is being determined. Accelerometer and magnetometer data along three orthogonal axes of a measurement sub are used to obtain unit gravitational vectors ~ at a first time and at a second time and unit magnetic vectors ~ at the first time and the second time. The difference between the two unit gravitational vectors at the different times, .DELTA.~, and the difference between the two unit magnetic vectors at the different times, .DELTA.~, are used along with the unit vectors ~ and ~ and the difference in time .DELTA.t to determine the rotation vector of the probe ~ which has occurred during such time difference. The vector representing the rotation of the earth, ~ is then determined by subtracting ~ from the vector ~ from three gyroscope instruments placed along the axes of the measurement sub. The heading of the drill string is determined from the gravitational vector and the earth rotation vector.
