Title: System for improving the quality of a received radio signal
Inventor: CHENNAKESHU SANDEEP
IPC: H04B7/00
Filed: 1997-12-10
Granted: 1999-06-21
Abstract: A delay spread is created in a digital radio signal to reduce the coherence bandwidth and facilitate frequency hopping to reduce the effect of fading losses within and enclosed propagation environment. The delay spread is introduced into the signal in several ways. One technique disclosed employs a transmitter with two separate antennas one of which transmits the digital signal and the other of which transmits the same signal after a phase delay has been introduced into the signal. The carrier frequency of the signals is hopped between at least two frequencies and the receiver processes the resulting signals. In another embodiment, a single transmit antenna is used but the signal is received by two different antennas with the output signal from one of those antennas being phase delayed before combining it with the other prior to processing by the receiver circuitry. Phase delay is also introduced at baseband into the signals to be transmitted by rotating the I and Q components of the waveforms before modulation.

Granted: 2000-09-11
Abstract: This invention is a kind of contact panel input apparatus whose topic is to provide the contact panel input apparatus with high transmission rate and rapid response. The solving means is to proceed tight sealing at the surrounding of the electric-conductive body layer (4) (5) of two sheets of transparent plate (2) (3); then, use the flexible reactive-type adhesion to solidify adhesive layer to form the electric-conductive body layer (4) (5) ,and open a little space to overlap support the tight-seal portion (10); next, inject the transparent insulated liquid (11) between the transparent plate (2) (3) tightly sealed according to the tight-seal portion (10). Since the transparent insulated liquid (11) is sealed, the reflective rate is lowered as the light transmission rate is increased; besides, since it adopts the reactive-type adhesion to adhere between the transparent plate (2) (3), the space between the transparent plate (2) (3) is being narrowed that could diminish the liquid quantity sealed inside; then, the movement quantity of the liquid (11) in the press position is reduced; and the response becomes rapid.

Granted: 2001-01-21
Abstract: The present invention provides a dielectric ceramic which exhibits an excellent electrostatic capacity-temperature characteristic; which allows use of a base metal such as nickel; which can be fired in a reducing atmosphere; and which is suitable for constituting a dielectric ceramic layer of a laminated ceramic electronic element such as a laminated ceramic capacitor. The dielectric ceramic is obtained by firing barium titanate powder in which a caxis/a-axis ratio in the perovskite structure is in the range of 1.003 to 1.010 and an amount of OH groups in the crystal lattice is 1 wt.% or less. The barium titanate powder serving as a starting material preferably has a maximum particle size of 0.5 mu m or less and an average particle size of 0.1-0.3 mu m, and individual particles of the barium titanate powder comprise a low-crystallinity portion 21 and a high-crystallinity portion 23, with the diameter of the low-crystallinity portion being less than 0.65 times the particle size of the powder. Moreover, when sintered, the powder satisfies the ratio of (average grain size of the fired dielectric ceramic)/(average particle size of barium titanate powder serving as a starting material), which is referred to as R, of 0.90-1.2, to thereby suppress considerable grain growth. The invention also discloses a laminated ceramic electronic element including a laminate of a plurality of layers of the above-mentioned dielectric ceramic, as well as a method for producing the same.

Title: Pseudo precise I-cache inclusivity for vertical caches
Inventor: ARIMILLI RAVI KUMAR
IPC: G06F12/08
Filed: 1999-02-10
Granted: 2001-04-01
Abstract: A modified MESI cache coherency protocol is implemented within a level two (L2) cache accessible to a processor having bifurcated level one (L1) data and instruction caches. The modified MESI protocol includes two substates of the shared state, which denote the same coherency information as the shared state plus additional information regarding the contents/coherency of the subject cache entry. One substate, SIC0, indicates that the cache entry is assumed to contain instructions since the contents were retrieved from system memory as a result of an instruction fetch operation. The second substate, SIC1, indicates the same information plus that a snooped flush operation hit the subject cache entry while its coherency was in the first shared substate. Deallocation of a cache entry in the first substate of the shared coherency state within lower level (e.g., L3) caches does not result in the contents of the same cache entry in an L2 cache being invalidated. Once the first substate is entered, the coherency state does not transition to the invalid state unless an operation designed to invalidate instructions is received. Operations from a local processor which contravene the presumption that the contents comprise instructions may cause the coherency state to transition to an ordinary shared state. Since the contents of a cache entry in the two coherency substates are presumed to be instructions, not data, instructions within an L2 cache are not discarded as a result of snooped flushes, but are retained for possible reloads by a local processor.

Title: Ash melting furnace and ash melting method thereof
Inventor: OSE KIMITOSHI
IPC: C22B7/02

Granted: 2001-12-11
Abstract: The object of this invention is to provide an ash-melting furnace which can respond to fluctuations in the load and which will be capable of highly efficient and stable operation. In an ash-melting furnace which heats and melts the primary ash and the fly ash obtained by combustion together, this invention is characterized by supplying the primary ash (ash containing rough particles) from upper end of the furnace to form an upper layer of a two-tiered layer of ash, supplying the fly ash (ash containing minute particles) from an upper end of the furnace to form a lower layer of the two-tiered layer of ash, moving the two-tiered layer together towards the far end of the furnace, and heating and melting the two-tiered layer by a burner to form molten slugs during the moving step. When the burner is an oxygen-enriched burner, this configuration makes it possible to control the volume of oxygen to be added to the burner air (including changing the density of the oxygen). This invention can control not only the volume of fuel but also the density of the oxygen-enriched air and the volume of the ash to be supplied in response to the state of flow of the molten ash melted by the oxygen-enriched burner.
