Title: Communication apparatus
Inventor: ISHIKAWA KO
IPC: H04B14/08
Filed: 1990-04-18
Abstract: A communication apparatus includes a transmission unit and a reception unit. The transmission unit superposes a subcarrier on one value of a baseband signal consisting of binary values, modulates a carrier with the baseband signal on which the subcarrier is superposed, and transmits the result as a transmission signal wave. The reception unit shown extracts the subcarrier from the demodulated signal using a bandpass filter 61, 62 or 70, and detects the baseband signal using an envelope detector 65, 66 or 72. As described the reception unit is an interrogator which transmits power/carrier f1 and interrogation signals f2 in the form of orthogonal polarised microwaves to the responder (Fig 2) which returns both a phase modulated version of the carrier f1 and an amplitude modulated version of a harmonic 2f1 thereof to the interrogator which compares at 21 the demodulated signals to reproduce a response or an error signal. <IMAGE>

Title: Methods for the high speed transmission of Chinese fonts or graphics via a printer port on a computer
Inventor: YANG JEN-TSUN
IPC: G06F3/00
Filed: 1991-10-10
Abstract: Data about Chinese fonts or graphics is transmitted via a printer port (11) on a personal computer (1) to a Chinese fonts or graphics generator (2) byte by byte, after being treated by the computer so that successive bytes are different. An automatic detection circuit detecting changes generates a control signal to notify the generator (2) that data is ready for retrieval so that the computer (1) does not have to send another control signal. A status signal is used by the generator for transmission of data to the computer; such data is encoded according to the continuous, incremental or decremental characteristics of the Chinese fonts or graphics to minimise the volume of data before it is transmitted; and after receipt of such data, the computer decodes it to restore the original data so that the generator can transmit data to the computer at high speed. <IMAGE>
Patent GB-2248862-A (GB)
Title: Structural member resistant to buckling
Inventor: IMAI KATSUHIKO
IPC: E04C3/08
Filed: 1991-10-11
Abstract: A structural member (1) resistant to buckling comprises two elongate members (2, 3) disposed one within the other. The elongate members (2, 3) are movable relatively to one another in the longitudinal direction so that an axial compressive load (P) applied to one of the elongate members (2) is initially not resisted by the other elongate member (3). When the elongate member (2) which initially resists the said axial compressive load (P) begins to buckle, the two elongate members (2, 3) come into contact and together resist buckling. Thus, member (2) is deformed in the axial direction only when it begins to deform plastically. When a buckling resistant structural member (1) of the type described above, is used in the construction of a truss, the truss is prevented from collapsing suddenly, since the structural members (1) are able to deform to a large extent and in a stable manner before failure occurs. Such an arrangement is particularly suitable for the construction of earthquake resistant building; the structural members (1) are capable of absorbing a large quantity of energy and hence should prevent the building from collapsing or at least delay collapse so that occupants of the building may escape. <IMAGE>

Title: Circuit for simultaneous amplification of signals with different frequencies
Inventor: HUUSKO RISTO
IPC: H03D7/00
Filed: 1991-11-07
Abstract: The present invention relates to a circuit with which first and second signals are amplified. The second signal, of which the frequency f2 is different from the frequency f1 of the first signal, is derived with the aid of a frequency changing operation (P) from the first signal. The circuit comprises a first diplexer (d1) for combining the first signal and the second signal entering the input of the circuit into a sum signal, an amplifier (A) for amplifying the sum signal, a second diplexer (d2) for separating from the amplified sum signal of frequency f1 + f2 the amplified second signal to be carried to the output of the circuit and the amplified first signal to be carried at least through frequency changing means (P) back to the first diplexer (d1). The circuit can be employed in amplifying radio frequency and intermediate frequency signals for a radio telephone. <IMAGE>

Title: Automatic ink-jet jetting-axis adjustments in ink-jet printers.
Inventor: MUTOH MASAYUKI
IPC: B41J2/125
Filed: 1993-02-22
Abstract: In an ink jet recording apparatus of the continuous jet type the position of an ink jet jetting axis or nozzle axis is automatically adjusted to an optimum position by a deflecting electric field. When a carriage is at its home position, jetting of ink from nozzle (1) is started, and a microprocessor MPU changes over a changeover switch SW to a test signal generator side. The test signal generator TSG generates a test signal, which is the sum of an amplified recording signal and a bias potential outputted from a bias power source BS, and applies the test signal to a controlling electrode 3. The microprocessor MPU checks an output of a current detector CD (jet current) based on charged ink drops caught by a conductive drop catcher 8 to discriminate the positional relationship between an ink jet jetting axis and a knife edge 5. The microprocessor MPU then changes the bias potential of the bias power source BS in accordance with a result of the discrimination. Consequently, the controlling signal applied to the controlling electrode 3 is varied to adjust the ink jet jetting axis to its optimum position. A similar method of adjustment is described wherein the adjusted bias potential is applied to the droplet generator rather than to the charging electrode. <IMAGE>

Title: Speech/facsimile transmission system
Inventor: SUZUKI SHIGEAKI
IPC: H04M11/00
Filed: 1993-06-29
Abstract: In a circuit multiplex transmission system for transmitting speech/facsimile signals, a transmission circuit allocation control unit 9 outputs a data transmission rate designation signal according to the load of the transmission circuit in order to designate a facsimile base band data transmission rate. The result is that since the facsimile base band data transmission rate is controlled according to the load of the transmission circuit, it is possible to accommodate the same number of input telephone lines as that if every input signal is a speech signal. <IMAGE>
