Abstract: The ball (34) of the second ball valve (30) has a ventilation opening (60). This is connected to the through bore (42) in the housing (32) of the fitment facing away from the first ball valve (10) when the second ball valve is closed. The ventilation bore is at right angles to the through bore (48) in the ball. The second ball seating ring (38) is axially movably mounted in an annular groove (52) in the housing of the fitment. An arrangement (56) of spiral springs or one or more plate springs is positioned between the second ball seating ring and the base (54) of the groove and prestresses the second ball seating ring towards the ball. An annular sealing element (58) is positioned between the spring arrangement and the ball seating ring. <IMAGE>

Abstract: The sealing device includes a shield (1) and an inflatable expansion body (2). The expansion body consists solely of a layer of elastic material. The expansion body, lightly inflated, initially takes the form of a hollow cone, rounded at the tip, extending from the shield.   When further inflated, it takes on a cylindrical form, fitting into the branch channel (3) and its angling towards the main channel (4). The inflatable body expands into the branch channel. When the pressure in it is relieved, it can be taken out of the branch channel.

Abstract: A data copyright management system comprises a database for storing original data, a key control center for managing crypt keys, copyright management center for managing data copyrights, and a communication network for connecting these sections each other; data supplied from the database to users is encrypted and distributed, and the users decrypting the encrypted data by crypt keys obtained from the key control center or copyright management center to use the data. 
     To supply data to users, there are the following two methods: one for one-way supplying encrypted data to users by means of broadcasting or the like, and the other for two-way supplying encrypted data to users corresponding to users' requests. 
     A crypt key system used for encrypting data uses a secret-key cryptosystem, a public-key cryptosystem or a cryptosystem combining a secret-key and a public-key and moreover, uses a copyright management program for managing data copyrights. 
     When a user stores, copies, or transfers data, the data is encrypted by a crypt key different from a crypt key used for supplying the data. The former crypt key is supplied from the key control center or from the copyright management center, or generated by the copyright management program. 
     Moreover, the present invention can be applied to a data copyright management system for using not only signal data but also a plurality of data supplied from a single database or a plurality of data supplied from a plurality of databases. 
     Furthermore, an apparatus to be used by the user to perform data copyright management is also proposed.

Abstract: An accelerated video controller operates in conjunction with a video driver to accelerate certain video operations. If the operating environment requests a polygon operation, the driver (or software on the video controller) will determine whether the specified polygon is simple convex. The determination of whether a convex polygon is simple convex is accomplished by tracing between the vertices of the polygon and comparing the changes in direction relative to a predetermine coordinate axis to a threshold number. If the polygon is simple convex, certain operations can be performed using simpler code or hardware accelerated features. For a polygon fill, if the polygon is simple convex, the edges of the polygon are inspected to determine whether the polygon can be decomposed into a rectangle and a smaller polygon. If so, the video controllers bit engine will be used to perform the fill of the rectangle at high speed, thus reducing the time of the operation.

Abstract: A device isolation method divides a semiconductor substrate into active and inactive regions. A first device isolation layer (38) is formed in a first inactive region using a trench isolation method.

Title: Ink-jet swath printer with auxiliary ink reservoir
Inventor: BOHORQUEZ JAIME H
IPC: G01D15/18
Filed: 1996-05-10
Abstract: An ink-jet swath printer employing a cartridge (50) with a spring bag primary reservoir (62) and an auxiliary ink reservoir (230) interconnected via a tube (240) to form a closed ink replenishment system. The primary reservoir creates a negative pressure which draws ink from the auxiliary reservoir as ink is expelled from the cartridge printhead (76) during printing operations. The auxiliary reservoir can either be mounted on the cartridge carriage (210) or on the printer body (202). The auxiliary reservoir is a large capacity collapsible bag mounted below the level of the printhead to establish an ink pressure head at the primary reservoir connection which is not so large as to destroy or diminish the negative pressure and allow ink to drool from the printhead, yet is sufficient to permit replenishment of the primary reservoir to avoid printhead ink starvation.

Abstract: The invention provides apparatus and a method for the analysis of the surface of a specimen by the techniques of electron energy spectroscopy and secondary ion time-of-flight mass spectrometry. For the former technique, the invention provides a substantially conventional electron energy analyzer (14), typically having hemispherical electrodes (46, 47). For the latter technique, the same energy analyzer is used as an ion deflector and in conjunction with a linear drift region (53, 54 of Fig. 3) and a pulsed primary ion beam gun (8) provides a time-of-flight mass spectrometer having at least first-order time focusing properties. By using the energy analyzer (14) in both techniques a combined instrument is provided at much lower cost than prior combined instruments which comprise different analyzers for the two techniques.

Abstract: Methods for compressing digital video signals that fully utilize temporal compression techniques. Each of the methods disclosed compresses digital video signals not only in the spatial domain, as with current implemented MPEG compression methods, but also in the temporal domain. A group of video signals is input to a signal compressor (16). The signal compressor (16) performs discrete cosine transforms in both the spatial and temporal domain. The transformed data is then input into a three-dimensional quantization matrix (18), where rate and distortion optimization parameters are calculated for compression purposes. In a first method, rate-distortion performance and transmission order are optimized for the quantized, three-dimensional transform coefficients. In a second method, rate-distortion performance is optimized for the quantized, three-dimensional transform coefficients. Temporal dequantization and inverse transform are performed before transmitting the two-dimensional transform coefficients in MPEG-compatible intraframe format. The data is transmitted to a signal decompressor (40).

Title: Multimode electromagnetic wave energy rejection filter arrangement for a slot waveguide
Inventor: BRODSKI YOURY
IPC: H05B6/76
Filed: 1997-03-29
Abstract: A multimode electromagnetic wave energy rejection filter arrangement for a slot waveguide includes at least one system of series coupled LC-circuits located, at least partly, within a cavity of the slot waveguide and arranged along a predetermined line intersecting the wave vectors of electromagnetic waves to be rejected, the LC-circuits including lumped elements and the coupling between the LC-circuits being substantially weak. The LC-circuits may be located, at least partly, within grooves formed in a wall of the slot waveguide. As applied to a heating apparatus employing high frequency electromagnetic wave energy or microwave energy for heating dielectric materials, the series coupled LC-circuits are arranged along a closed line which envelopes the access opening in a body of a multimode resonator heating chamber, in which the high frequency electromagnetic wave energy is employed for heating. By optimizing the parameters of the system of series coupled LC-circuits it is possible to provide rather low transmittance for a wide range of angles of incidence of waves, as well as to minimize the transmittance dependence on the angles of incidence of these waves. The later enables to achieve high protection against leaks of electromagnetic energy from the resonator heating chamber of a heating apparatus, for example, of a domestic microwave oven.
