Title: Base station apparatus of mobile communication system
Inventor: OHNO KOJI
IPC: H04B7/00
Filed: 1998-04-17
Abstract: A base station including a transmitting and receiving amplifier for amplifying CDMA signals exchanged with a mobile station; a radio stage connected to the transmitting and receiving amplifier for carrying out D/A conversion of a transmitted signal that undergoes baseband spreading, followed by quadrature modulation, and for carrying out quasi-coherent detection of a received signal, followed by A/D conversion; a baseband signal processor connected with the radio stage for carrying out baseband signal processing of the transmitted signal and the received signal; a transmission interface connected with the baseband signal processor for implementing interface with external channels; and a base station controller for carrying out control such as management of radio channels and establishment and release of the radio channels. The base station communicates with the external channels using ATM cells, and with the mobile stations using the CDMA signals by mapping a plurality of logical channels into a plurality of physical channels. The CDMA signals are spreading using two types of spreading code sequences, that is, a short code and a long code.

Title: Dosage forms and compositions for osmotic delivery of variable dosages of oxycodone
Inventor: FINK TRACY ANN
IPC: A61K9/22
Filed: 2003-05-28
Abstract: Dosage forms, compositions and methods for the controlled release of oxycodo ne over a prolonged period of time are described. The present invention disclos es a novel means for delivering varying doses of oxycodone using a drug composition having only oxycodone, a polymer carrier and varying amounts of salt to provide a particular viscosity of the hydrated drug core for deliver y of the drug at the desired release rate. The present invention functions by modulating the viscosity of the hydrated drug layer in operation by the addition or reduction of salts in the drug composition. The system is independent of solubility enhancers or pH modifiers. The sustained release dosage forms provide therapeutically effective average steady-state plasma oxycodone concentrations when administered once per day.

Inventor: OKUMURA HIRAKU
IPC: H04M1/20
Filed: 2005-03-22
Abstract: An apparatus is designed for processing a first audio signal at transmission and a second audio signal upon receipt so as to determine whether the second audio signal is provided under a double-talk state or a single-talk state. In the apparatus, a storage section stores the first audio signal. A convolution section convolutes the stored first audio signal with a variable coefficient to produce a reference signal. The variable coefficient is updated by an update addition value. A subtraction section subtracts the reference signal from the second audio signal to provide an error signal. A computation section computes the update addition value for the variable coefficient on the basis of the error signal and the first audio signal. A determination section determines whether the second audio signal is provided under the double-talk state or the single-talk state on the basis of the update addition value.

Abstract: A dual density powder metal mechanical face seal seat is provided including a hub portion integrally formed as a unitary piece with a seat portion. The face seal seat is formed of powder metal that has a higher density in the hub portion than in the seat portion. The higher density hub portion provides the seal seat with greater strength characteristics where the seal seat mounts to a shaft. The lower density seat portion allows greater amounts of lubrication to be impregnated in the seal seat portion where it is needed while a smaller amount of lubrication is provided in the hub portion where it is not needed. The higher density hub portion has a higher coefficient of thermal conductivity to draw heat away from the seal seat portion. The smaller pores in the hub portion provide a capillary effect to cause lubrication impregnated in the seal seat to be sucked back into the pores when the seal seat is not rotating. The duel density powder metal also eliminates the necessity to mask portions of the seal seat while the seal seat is being impregnated with lubrication since the dual density regions automatically control the impregnation amount in the different regions.
