Title: Digitally frequency-locking a radio transceiver to the received signal
Inventor: MOLLER PAUL J
IPC: H04B1/40
Filed: 1991-01-11
Granted: 1994-05-17
Abstract: A unique cellular telephone (100) digitally frequency locks to the received base station transmitter signal. The cellular telephone (100) includes a radio transceiver (106), a reference oscillator (104), and microcomputer (102) with memory therein for controlling the operation thereof. The radio transceiver (106) includes a phase-locked loop (PLL) synthesizer 120, a receiver mixer (122) followed by one or more gain stages (124), a phase detector (126), and a divider (128). The PLL synthesizer (120) generates a signal locked to the reference oscillator (104) that is mixed with the incoming base station transmitter signal in the receive mixer (122) to generate an intermediate frequency signal. The output of the reference oscillator (104) also feeds the divider (128), which divides the reference oscillator signal by an amount so as to generate the divided signal having a frequency substantially the same as the frequency of the intermediate frequency signal from the mixer (122). The output of the divider (128) and the amplified intermediate frequency signal from the amplifier (124) are both fed into the phase detector (126), which generates a binary error signal (110). The microcomputer (102) is responsive to the binary error signal (110) for frequency locking reference oscillator 104 to the received base station transmitter signal.

Title: Vacuum coupling arrangement for applying vibratory motion to a flexible planar member
Inventor: SNELLING CHRISTOPHER
IPC: G03G15/16
Filed: 1991-06-11
Granted: 1996-03-26
Abstract: A resonator suitable for generating vibratory energy is arranged in line contact with the back side of a charge retentive member bearing an image on a surface thereof, in an electrophotographic device, to uniformly apply vibratory energy to the charge retentive member. The resonator comprises a vacuum producing element, a vibrating member, and a seal arrangement. When the vibratory energy is to be applied to the charge retentive surface, a vacuum is applied by the vacuum producing element at the point of contact with the charge retentive surface resonator, to draw the surface into intimate engagement with the vibrating member, and seal arrangement. The invention has application to a transfer station of enhancing electrostatic transfer for toner from the charge retentive surface to a copy sheet, and to a cleaning station, where mechanical vibration of the surface will improve the release of residual toner remaining after transfer.

Title: Impedance-matching coupler
Inventor: MARGULIS WALTER
IPC: H01P3/08
Filed: 1990-12-06
Granted: 2001-05-29
Abstract: The invention relates to the coupling of electric signals to and from high-speed electronic components, being particularly suited to couple high-frequency signals or very host pulses to diode lasers, and from high-speed photodiodes. The coupler consists of a device formed by joining at least two diverse planar transmission-line structures, the central signal-carrying conductor (22, 31) being shared among all the structures so joined, while the ground planes (26, 27, 29; 32, 33; 34, 36) maintain the positional relationship to said conductor that characterize each of the structures so joined. The characteristic impedance change, from 50-ohm usual line impedance to 5-ohm diode impedance is achieved gradually along the device through the cumulative effect of the individual impedance changes of each transmission-line structure forming said coupler, which result from the gradual change of the dimensions of the cross-section along said coupler.

Title: Method of processing image data
Inventor: NAKAGAWA YOSHIHIRO
IPC: B41J2/01
Filed: 1992-12-21
Granted: 2000-04-25
Abstract: At a data output apparatus side, raster image information, which is obtained by means of performing an exclusive OR operation between raster image information on the preceding line and raster image information on the current line, is compression-processed in a raster direction and then transmitted to a data processing apparatus. In the data processing apparatus, the received image information is expansion-processed, an exclusive OR operation between image information after the expansion and image information on the preceding line is carried out, and a processing for recording and the like is performed taking the thus obtained information as the raster image information on the current line. Thus it is possible to provide a higher compression rate of the image information with a simple processing and to improve a processing speed.
