Title: Spread spectrum data demodulation with phase correction
Inventor: MURAI HIDESHI C O MITSUBISHI D
IPC: H04B1/707
Filed: 1995-02-22
Abstract: A data demodulator circuit for spread spectrum communication, presenting improved demodulation characteristics by allowing the elimination of the influence of a carrier offset remaining after down converting, and the removal of the interference caused by pilot signals with different timing. In-phase axis received signal and quadrature axis received signal are provided to data demodulator circuits adapted to operate with their respective reception timing of pilot signal. A phase difference information extracting means extracts phase difference information from the input signals, and delay means delays the received signals so as to ensure that extracted phase difference information is equivalent to the amount of average phase revolution. A frequency and phase compensation means eliminates the influence of the carrier offset by use of thus extracted phase difference information. A data demodulation means with canceler removes an interference I DF  of pilot signals with different timing originating from the outputs of an interference amount calculating means.

Abstract: A stack of oxide (16) and silicon nitride (18) is grown/deposited over a patterned polysilicon line, which typically acts as a bottom capacitor plate. A thin layer of amorphous or polycrystalline silicon (20) is deposited over the blanket silicon nitride film. The thickness of the deposited silicon layer must be optimized according to the final amount of oxide desired over the silicon nitride, which will be roughly twice the thickness of the deposited silicon film. The oxide/nitride/silicon stack is then patterned and etched, stopping either at or underneath the bottom oxide. Any subsequent cleaning in potentially oxide-etching chemistries (including HF) is done with the protective silicon deposit on top of the silicon nitride. The entire structure is then thermally oxidized, transforming the deposited silicon into silicon oxide (30). Where the structure has been cleared down to the substrate by etching, a second gate oxide is simultaneously formed.

Abstract: In a wireless telephone of a mobile communication system, which performs transmission in series of bursts, in synchronism with a receive signal transmitted from the base station, each burst of transmission being performed responsive to a transmission timing signal, a sync signal is detected from the receive signal, the transmission timing signal is generated on the basis of the sync signal, and a each burst of transmission is effected in accordance with the transmission timing signal. When the sync signal ceased to be detected, said transmitting timing signal is autonomously generated for a certain time period after the sync signal is last detected. In another aspect of the invention, during reception in a first channel, the channel quality of another vacant channel is measured by transferring PLL data to the PLL prior to the slot in which the measurement is effected. In a further aspect of the invention, bit stream data transmitted from the base station is converted into byte stream data and used for control within the wireless telephone.

Abstract: Public networks for distribution of video and/or audio-signals are point-to-multipoint networks. Signals are transmitted from a main station to several subscribers. The public network is decoupled from the home network. Network termination units (NT1,NT2) transmit selected signals in digital form to set-top boxes (STB1,STB2,...STBTf) near the subscriber using redundant modulation. The network termination units feed the telephone signals selectively into the public network from the subscribers. Alternatively, the telephone signals are transmitted via extra lines to a position indication point (OVSt).

Abstract: The separation device (30) includes a container having a dome-shaped base (32) and a peripheral wall (34) surrounding the base to define a chamber for receiving a random mixture (16) of defective and nondefective articles. A spiral-shaped ramp on the peripheral wall (34) which surrounds the chamber and overhangs the base, leads to an elevated outlet opening (46). A vibrating device vibrates the chamber to excite movement of the defective and nondefective articles along the base and onto and up the ramp toward the outlet opening (46). The container also includes trap openings (54,56) in the base and ramp to eliminate defective articles from the chamber. Discriminating devices are provided on the ramp that cause defective material to fall from the ramp back onto the base of the chamber. Only the nondefective articles can move on the ramp past the trapping devices toward the outlet of the container for transfer to another processing station.

Abstract: An ultra-fine microfabrication method using an energy beam is based on the use of shielding provided by nanometer or micronmeter sized micro-particles to produce a variety of three-dimensional fine-structures which have not been possible to produce by the traditional photolithographic technique which is basically designed to produce two-dimensional structures. When the basic technique of radiation of energy beam and shielding is combined with a shield positioning technique using magnetic, electrical field or laser beam, with or without the additional chemical effects provided by reactive gas particles beams or solutions, fine-structures of very high aspect ratios can be produced with precision. Applications of devices having the fine-structure produced by the method include wavelength shifting in optical communications, quantum effect devices and intensive laser devices.
