Title: Magnetron with increases stability
Inventor: MULCAHY BERNARD RICHARD
IPC: H01J23/213
Filed: 2001-07-14
Abstract: A magnetron comprises a plurality of anode vanes 12-19 and straps 20, 21, 22 in contact ith alternate ones of the vanes. Each strap comprises an open ring having two free end portions. The end portions of each pair overlap in a spaced relationship to provide a capacitance in use. The provision of a capacitance in the, or each, strap ring increases the stability of operation of the magnetron in the wanted   f   mode and limits oscillations at undesired frequencies. Preferably, the capacitance is variable. This may be realised by arranging so that the relative distance between the end portions is adjustable. In a further described embodiment (Fig. 8), an intermediate strap portion (46) is used along with the open ring strap free ends (49, 50) to provide the capacitance.

Title: Lightweight rubber composition containing clay
Inventor: AJBANI MANOJ
IPC: C08K7/00
Filed: 2001-11-16
Abstract: This invention relates to a light weight rubber blend that can be beneficially used in rubber articles, such as power transmission belts and tires. In the rubber blends of this invention a 2:1 layered silicate clay, preferably an organophilic 2:1 layered silicate clay, is substituted for a portion of the carbon black that is normally used in the rubber as a filler. This can be done without sacrificing the physical properties of the rubber composition in cases where the rubber in the blend contains an amino group. Tire tread compounds that utilize such rubber compositions offer increased vehicle fuel economy. This invention also relates to improving the strength, modulus and elongation of carbon black and silica filled compounds by the addition of 2:1 layered silicate clays thereto without modifying the level of carbon black or silica. Such compounds have increased flexibility and tensile strength for tire side-wall applications and improved traction and cornering performance in tire treads. This invention more specifically discloses a light weight rubber composition that is comprised of: (1) an amino group containing rubbery polymer, wherein said amino group containing rubbery polymer contains from about 0.1 weight percent to about 20 weight percent of a monomer containing an amino group, (2) from about 0.1 phr to about 25 phr of a 2:1 layer type silicate clay, and optionally (3) a silica coupling agent. The present invention further discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads; wherein said tread is adapted to be ground-contacting; wherein the tread is comprised of the rubbery polymer of this invention.

Title: Data compression encoding where groups of character whose codes exactly fill a transmission data unit are stored in the encoding table
Inventor: MURASHITA KIMITAKA
IPC: H03M7/42
Filed: 1997-09-01
Abstract: Input data including a plurality of elementary data elements is encoded into data units having a fixed data length as follows. Combinations of consecutive elementary data elements in the input data are first detected which match identified combinations as represented by data encoding information used to encode the data (see below). Each matching combination of elementary data elements is then encoded using its corresponding data unit as represented by the data encoding information. The corresponding data unit is then outputted. The data encoding information is produced by first assigning to each elementary data element a code having a code length corresponding to a frequency of appearance of that elementary data element. Combinations of elementary data elements are then identified for which a total length of the codes assigned to the elementary data elements in that combination is equal to the fixed data length. The data encoding information is then created based on the identified combinations to represent a correspondence between each identified combination of elementary data elements and such a data unit, the data unit corresponding to each identified combination having the fixed data length and including the codes assigned to the elementary data elements of that combination.
