Abstract: Système de communication cellulaire comprenant les communications de voie d'aller en direction des utilisateurs et les communications de voie de retour correspondant en provenance des utilisateurs mobiles. Les utilisateurs se déplacent d'une région à l'autre en traversant une ou plusieurs zones. Les communications de voie d'aller sont transmises directement aux utilisateurs dans une zone d'émetteur. Les communications de voie de retour en provenance des utilisateurs ne sont pas renvoyées directement mais sont rassemblement d'abord en des sites répartis dans l'ensemble de la zone d'émetteur, puis retransmises afin d'achever les communications en duplex. Les communications de voie d'aller sont du type point à multipoint tandis que les communications de voie de retour sont du type multipoint à point. Dans ce système de communication, le trajet d'aller point à multipoint s'effectue par transmission directe, et le trajet de retour multipoint à point passe par plusieurs points de rassemblement. Etant donné que les trajets d'aller et de retour ont des configurations indépendantes, ledit système optimise à la fois le trajet d'aller et le trajet de retour.

Title: Receiving apparatus for spectrum spread system
Inventor: YAMADA DAISUKE
IPC: H04B1/7073
Filed: 1997-03-26
Abstract: A spectrum spread receiver is provided with a delayed waveform phase determination circuit which determines whether or not a detected delayed waveform is in the phase as the previously-detected delayed waveform, and outputs a delayed waveform switch signal if they are out of phase with each other. If the delayed waveform switch signal is in an ON state, on the basis of the signal despread by a second despreading circuit 7 and the delayed waveform switch signa, a demodulation circuit 9 demodulates the first half and second half of a received signal, as a boundary is a received signal at which a delayed waveform switch signal is turned on, by using the phase estimated from a first known signal and the phase estimated from a second known signal, thereby preventing the received signal from becoming degraded.

Abstract: A heterojunction bipolar transistor with a vertically integrated profile includes a substrate layer, a collector contact layer, a collector layer, a base layer and an emitter layer, formed from AlGaAs, etched to form an emitter mesa leaving a relatively thin passivating layer, adjacent the emitter mesa. The base metal contacts are formed on the passivating layer, resulting in a wider bandgap, thus minimizing surface recombination velocity at the emitter-base junction and increasing the overall gain (β) of the device. The base metal contacts are formed by evaporating a p-ohmic metal onto the n-type passivation layer. The p-ohmic contacts are annealed, resulting in p-type metal diffusion through the passivating layer and reaction with the base layer, resulting in ohmic contacts.

Abstract: A decoding method includes using a plurality of first bitstreams that are obtained by dividing a main bitstream with a hierarchical structure as inputs, successively arranging the plurality of first bitstreams and arranging specified second bitstreams before first hierarchical information of specified bitstreams among bitstreams constituting a specified hierarchy in the main bitstream, each second bitstream being such that at least one of codes including portions of the second bitstream does not correspond to specified code tables that are used for decoding bitstreams, thereby forming a third bitstream. Consequently, even when first bitstreams at intervals are input at fast forward play and fast reverse play, and codes at the vicinity of connection parts between the first bitstreams are recognized as codes different from the original codes to be decoded, data different from the original specified bitstreams are not decoded, thereby obtaining a decoding method and a decoding apparatus in which normal decoding operation is possible at trick play, such as fast forward play and fast reverse play. Further, error detection is securely performed immediately before the first hierarchical information, and the third bitstream is not parsed as far as a part after the connection part between the first bitstreams, at which part a syntactic error clearly occurs. Therefore, the decoding means does not take wasteful time, and time required for the following normal decoding operation can be reserved.

Abstract: When a converter 14 is rotated via a rotation mechanism 17, the
arrangement inclination angle of two primary radiators 15a and 15b can be
adjusted in the range of 0 to 20 deg. with respect to an axis which is in parallel
with the ground. Also the reception polarization angle due to probes of the
primary radiators 15a and 15b can be adjusted in the range of 0 to 20 deg.
while maintaining a preset difference in polarization angle among the satellites.
Therefore, the arrangement inclination angle of the primary radiators 15a and

polarization angle in the primary radiators 15a and 15b can be simultaneously
easily adjusted by rotating the converter 14 via the rotation mechanism 17.

Abstract: A fluid sensor for heat exchanger system includes a
supporting device such as a tubular hose fitting for
mounting the sensor in the system so that heat exchanging
fluid circulated in the system comes into contact with the
sensor. A window or sight glass is mounted in the
supporting device along with corrodible separating means
interposed between the sight glass and the heat exchanging
fluid. A visual indicator such as a movable flap or a
coloured ball can be viewed through the sight glass when
the separating means is ruptured or broken by corrosion.
The viewing of the indicator provides an indication that
the heat exchanging fluid has reached a certain corrosive
state and requires replacement or treatment. In a preferred
embodiment, the separating means is a metal diaphragm
spaced from the sight glass. The diaphragm can be made of
one corrodible metal while a ring in which the diaphragm is
mounted can be made from a different nobler metal so that
the diaphragm and ring form an anode and a cathode of a
galvanic couple.

sentence, a combined code sentence forming section 14 forms
a combined code sentence by combining together the secret
key code sentence and the publicized key code sentence.

Abstract: An implementation of a Butler matrix transformation used to process
antenna signals and, in particular, to transform signals obtained from an N-port antenna
into mode signals used for direction finding and other purposes. A reverse transformation
is used when the antenna is operating in a transmit mode. Instead of using a single Nth
order transformation matrix, the circuit of the invention employs a decomposed form of
the transformation matrix, thereby reducing the complexity of the transformation by using
lower-order matrices. In an example of the invention for an 8×8 transformation, the circuit
complexity is further reduced by using an additional level of decomposition, in which
phase shifting is effected by a circuit implementation of a single 8×8 diagonal phase shift
matrix requiring only three phase shift circuits. Reduction in circuit complexity,
particularly in the number of phase shift circuits, reduces bias errors in the overall
transformation and reduces fabrication cost.

Abstract: In a cellular mobile communication system, each base station is
allocated common frequencies shared with other base stations in addition
to unique frequencies. One of the unique frequencies is assigned by a base
station to a mobile terminal in response to a call request. The field strength
of a signal from that mobile terminal is detected and one of the common
frequencies is assigned to it if the detected field strength becomes lower
than a threshold. The base station receives a field strength signal from a
neighboring station indicating the strength of a version of the signal
received at the neighboring station and compares it with a threshold, and
combines the direct signal from that mobile terminal with this version of
the signal relayed from the neighboring station when its field strength is
higher than the threshold. At the given mobile station, a signal from the
base station which assigned the common frequency is combined with a
signal from the neighboring station. In a modification, the field strength
of signals from surrounding base stations is detected by mobile terminals
and a start-of-diversity-mode request is transmitted when the field
strength of one of the surrounding stations is higher than a threshold and
an end-of-diversity-mode request signal is transmitted when the field
strength of such a surrounding station is lower than the threshold. The
base station responds to these requests for effecting diversity reception.
