Title: Bus coupling information processing system for multiple access to system bus
Inventor: UMETSU MASAKAZU
IPC: G06F13/364
Filed: 1994-01-27
Granted: 2000-01-18
Abstract: When a first bus master device issues a bus request on a first request signal line, a centralized arbitration circuit in a system bus manage circuit issues a bus grant signal on a first grant signal line if the bus is available for use. This causes the first bus master device having gained the ownership of the bus to issue a read request to a first slave device. At this time a first signal line is designated. Even before the sending of the read data constituting a response to this read request to the first bus master device, a bus request from a second bus master device can be accepted if the data bus is unoccupied.   Thus, the centralized arbitration circuit in the system bus manage circuit issues a grant signal on a second grant signal line. This causes the second bus master device having gained the ownership of the bus to designate a second end signal line, and to issue a read request to a second slave device. After that, the first end signal line is activated, and read data from the first slave device is sent to the first bus master device. On the other hand, the second end signal line is activated, and read data from. the second slave device is sent to the second bus master device.

Abstract: A reduced size three-terminal type capacitor for removing jamming signals from an electrical signal.  The three-terminal type capacitor comprises a ceramic substrate with a first ground electrode layer formed on the ceramic substrate, and a first dielectric layer formed on the first ground electrode layer. On the first dielectric layer reaching at least from one end of the first dielectric layer to the other end is a signal electrode.  A second dielectric layer is formed on the first dielectric layer to surround the signal electrode together with the first dielectric layer, and a second ground electrode layer is formed on the second dielectric layer together with the first ground electrode layer.  The second ground electrode layer is electrically connected to the first ground electrode layer.  The structure of this three-terminal capacitor is such that first and second conductive layers (i.e. dielectric layers) are surrounded by mutually conducting first and second electrode layers so that jamming signal removal is superior to that of the conventional printed type capacitor.

Title: Method and apparatus for transferring data between a host processor and a subsystem processor in a data processing system
Inventor: CHERICHETTI CORY A
IPC: G06F13/28
Filed: 1994-08-12
Granted: 1999-05-18
Abstract: Data  is  transferred  from  a  host  system  to  a  subsystem connected to the host by a system bus in an efficient manner using one or more virtual first in first out (FIFO) registers in host memory and a corresponding set of virtual FIFOs located in the subsystem memory.  A transmission controller controls the transfer of data from the host FIFOs to the subsystem  FIFOs  while  the  subsystem processor  reads  and processes data from the subsystem FIFO. By accumulating data in the host FIFOs before transfer to the subsystem, overhead associated with starting and stopping data transfers over the system bus is substantially reduced.

Granted: 2003-12-30
Abstract: The present invention is directed to a process for the manufacture of porous cellulose matrices with a defined particle size and a significantly higher porosity (i.e. pore volume) than conventional formulations, such as pellet formulations containing cellulose and binders. The process is applicable on a wide variety of substantially dry cellulose raw materials. The cellulose is mechanically treated with low adhesion to the process equipment during a controlled gradual addition of an aqueous based fluid, optionally containing a surface-active ingredient, into regular particles, which are finally dried to obtain dry porous cellulose matrices. The so obtained matrices can be used as carriers for bioactive substances in multiple-unit preparations or tablets.

Title: Method of honing a knife blade
Inventor: LUDWIG ANDRE
IPC: B24B33/08
Filed: 1995-11-14
Granted: 1997-05-15
Abstract: A chipping blade of the type used in the forestry industry is sharpened initially by grinding an incline surface between two parallel side surfaces of the blade so as to form a sharpened junction between the incline surface and one side surface. The grinding action generates a burr wire or bead at the junction and this is removed in a honing action in which the blade is inserted into the cusp between two rotating honing bodies and moved back and forth. The honing bodies each comprise a series of honing discs at axially spaced positions on a shaft so that the discs of one body intermesh with the discs of the other body by a distance greater than 1 inch. The discs are formed from stacked sheets of woven fabric so that the cylindrical outer surface is compressible and fibrous.

Filed: 1995-12-12
Granted: 2005-07-05
Abstract: Mutant glycosidase enzymes are formed in which the normal nucleophilic amino acid within the active site has been changed to a non-nucleophilic amino acid. These enzymes cannot hydrolyze disaccharide products, but which can still form them.      Using this enzyme, oligosaccharides are synthesized by preparing a mixture of an .alpha.-glycosyl fluoride and a glycoside acceptor molecule; enzymatically coupling the .alpha.-glycosyl fluoride to the glycoside acceptor molecule to form a glycosyl glycoside product using the mutant glycosidase enzyme; and recovering the glycosyl glycoside product. Particular enzymes include a mutant form of Agrobacterium .beta.-Glucosidase in which the normal glutamic acid residue at position 358 is replaced with an alanine residue.

Abstract: A trainable transceiver for learning and transmitting an activation signal that includes a rolling or other variable code for remotely actuating a device, such as a garage door opener. The trainable transceiver preferably includes a receiver, a signal generator, and a controller operating in a learning mode or in an operating mode. In the learning mode the controller recognizes the presence of a variable code, identifies a prestored cryptographic algorithm related to the cryptographic algorithm used by the remote transmitter to generate the variable code, and stores data identifying the cryptographic algorithm and last transmitted code of the activation signal. In the operating mode, the controller generates output data representing a next sequential code of the variable code using the identified cryptographic algorithm and the data representing the last transmitted code. The signal generator receives the output data from the controller and transmits a modulated signal, which corresponds to a received activation signal and includes a variable code recognizable by a receiver of a remotely actuated device.
