Abstract: The present invention has the object to decrease the peak factor of a
transmission signal and control impulse noise. The amplitude
characteristics are identical to those of a normal root Nyquist filter, and the
phase characteristics divide the passband into a plurality number, the root
Nyquist filters having the phase corresponding to each bit value of PN codes
with the length of the divided number are set on transmission and reception.
Accordingly, even when the transmission signal has a high amplitude peak
and a short connection time, the signal can be transmitted along the route by
decreasing the peak to control the peak factor. Also, impulse noise can be
restrained at reception.

Abstract: Regular burst signals from video line (n+0) to line
(n+3) are replaced by modified burst signals which function as
copy prohibit signals. The phase of the modified burst signals
is controlled by controlling at least one of the orthogonal
vectors into which the phase of the regular burst signal is
resolved, and the phase vector of the modified burst signals is
equal to the average value of the phase vector of the regular
burst signals in lines (n+0) through (n+3). The phase vector of
the modified burst signal in line (n+2) exhibits a phase
difference of 135° from the phase vector of the original regular
burst signal in that line and causes image disturbances when the
thus-modified video signal is recorded and reproduced by a VCR.
The phase vector of the modified burst signal in each of lines
(n+0), (n+1) and (n+3) exhibits a difference as small as 45° from
the phase vector of the original regular burst signal in those
lines.

IPC: G11B20/10

Abstract: A method and system retrieving data stored on a compact disk read
only memory (CD-ROM) device using the constant angular velocity (CAV)
reading technique. Unlike the constant linear acceleration (CLA) reading
technique, in the CAV reading technique the data retrieval rates of the CD-ROM
read head vary depending on the radius of the annular recording track
that is being read. Data rates can be as much as 2.5x faster for the outer
recording tracks compared to the inner recording tracks. The novel system
utilizes a narrow capture band phase lock loop circuit in conjunction with a
microcontroller which controls the center frequency supplied to the phase
lock loop circuit. The microcontroller adjusts the center frequency of the
phase lock loop circuit depending on the track (e.g., radius) position of the
read head of the CD-ROM device. With the center frequency adjusted close
to the data rate of the current track, the phase lock loop circuit needs only a
narrow capture band to accurately retrieve the read reference clock from the
current track. In one embodiment, the microcontroller is aware of the read
head position because it controls read head movement. A microcontroller
controlled programmable oscillator (e.g., synthesizer) is used in one
embodiment of the novel system to generate the required center
frequencies. Direct computation or a look-up table based on the read head
position can be used by the microcontroller to determine the required center
frequencies. A decoder is supplied with the read reference clock for data
decoding.

Abstract: A method and system for handling incoming calls when no destination
stations are available. When an incoming call from an originating station is
received, it is determined whether a destination station is available. If a
destination station is not available, a telephone number of the originating station
is stored, Shortly before its current call is concluded, a destination station
indicates its approaching availability. Responsive to this indication, an outgoing
call is placed to the originating station. If the originating station does not
answer the outgoing call within a predetermined time, the outgoing call is
terminated and rescheduled. If the originating station answers the call within a
predetermined time, the outgoing call is connected to the available destination
station.

Abstract: An encoder (1) demodulates an input signal of a program. Main data (8)
of the program are recorded in a recording medium (3) as main information in
the form of data blocks. Auxiliary information (Figs. 2A-2K) of the program
are recorded in the recording medium as packs having a fixed length shorter
than a length of the data block. A memory (2) temporarily stores designated
auxiliary information of a concerned program in connection with identification
information of the recording medium in response to a recording of the main
data into the recording medium. A controller (100) causes the encoder to read
all of the auxiliary information of the program stored in the memory at a time.
The readout auxiliary information have same identification information
corresponding to the same recording medium. The readout auxiliary
information are modulated as packs and recorded in the subcode areas (13) of
the recording medium having the corresponding identification information.

     A pressure chamber (196) communicates with the outlet
valve, and comprises a control actuator (104), including a
diaphragm !194) retained between the pump body and plate,
which actuator extends though a control aperture (202) in
the pump plate selectively to enable and disable the pump in
dependence on pressure in the pressure chamber, a pump
outlet (102) communicating with the pressure chamber. 
     A dump/yield valve (122) releases excessive pressure in
the pressure chamber. A switch button (30) operates the
pump, the switch button serving to adjust spring bias (284)
on the valve between a first high value in which the valve
serves as a yield valve, and a second low value, where the
valve serves as a dump valve.

Abstract: A plurality of linear images are cut, the cut linear
images are scanned successively on other images to detect
positions where the degree of similarity is high, and these
detected coordinate values are partially combined, and when
the image is collated, combinations which does not satisfy
the relative positional relation corresponding to these
linear images are excluded from the processing target with
reference to the relation between coordinate values of the
detected positions. The image collation device thus enables
a fingerprint collation device to obtain collation result
consistently within a short time.

Abstract: A method for fabricating a memory integrated circuit having
a storage capacitor, the method including the step of forming a
transistor having a contact region 453 at a surface of a
semiconductor substrate. The transistor, excluding the contact
region is then covered with a first material 462, 466. The
contact region and first material are covered with a layer of a
second material 470, which is then planarized using a technique
such as chemical-mechanical polishing. Portions of the layer of
second material are removed to form a cavity having a bottom
made of the first material and sides made of the second
material. The cavity also exposes the contact region. A first
conductive layer of polysilicon 472 for example is then formed
in the cavity to conform to the bottom and sides. The first
conductive layer also extends over the surface of the first
layer 470. This portion of the first conductive layer may then
be selectively removed from the portion of the layer 472 in the
cavity by chemical-mechanical polishing, given the planar nature
of the underlying layer 470. The process continues with the
formation of a dielectric layer over the first conductive layer
in the cavity and with the formation of a second conductive
layer, the field plate, over the dielectric layer.
