Abstract: In an ultrasonic motor wherein a driving signal is applied to an electro-mechanical energy conversion element provided in a vibration member to thereby excite flexural vibrations of the same shape in the two different planes of the vibration member with a phase difference in time and thereby create rotational motion on the surface of the vibration member, thus frictionally driving a movable member which is in pressure contact with the vibration forming surface, electro-mechanical energy conversion elements for exciting the flexural vibrations are each disposed at a position whereat the sum totals of strains created in the electromechanical energy conversion elements are substantially equal to each other.

Abstract: In a method for the correlative digital signal processing at the receiver end in a system for transmitting digital information having fixed-duration signal shapes, multiplications of received signal X and reference signals Yi and accumulations of the products are carried out in the course of n clock steps in a systolic arithmetic circuit (4). During the time when the input (1) of the arithmetic circuit (4) receives digitised samples X of the received signal, the input (2) is supplied with suitable reference values from a digital memory (9) which is connected to the address counter (10), and the accumulation values Ai already accrued are input at input (3) for adding up further products X.Yi. With the aid of a synchronising device (14), the digital circuit (8) controls the appropriate provision of the reference values Yi from the memory (9) and ensures that the registers of the arithmetic circuit (4) are emptied at the beginning of each signal shape to be received, and that the n accumulation values are successively read out of the register Rn of the arithmetic circuit (4), with open feedback loop from the output (6) to the input (3), via the connection (7) at the end of each signal shape duration and are processed further so that the received digital information items become available at the output (13) of the digital circuit (8). Using a device according to the method described, it is possible to build up matched filters operating purely digitally for signal shapes of a large variety in a simple and perfectly reproducible manner. Because of the low costs of such a structure, which can be achieved by large-scale integration, for example power supply grids can be opened up as a reliable medium for transmitting digital information by means of a band spreading technique, for example by means of frequency shift keying, for a large variety of applications. Complete modems consisting of transmitter and receiver can be implemented which can be widely adapted to various requirements, for example with respect to data rate and resistance to interference, due to their purely digital mode of operation.

Abstract: A method and apparatus are disclosed for the calibration of a multichannel printer. The printer comprises a plurality of diode lasers which are modulated in accordance with an information signal. Radiation from the diode lasers is imaged onto a receiving medium such as a thermal print medium. The thermal print medium is supported on a drum which is rotatable about an axis. In order to balance the output from the diode lasers, test patterns are formed on the receiving medium with each of the lasers using known power inputs. The density of each of the test patterns is measured, and the density values obtained are correlated with the input power levels for each of the lasers. The measurement of densities produced by a single laser is facilitated by slowing the print head down by a factor of the number of lines normally printed and writing with one line source at a time.

Abstract: An interface transceiver (16) circuit and method for communicating transceiver control and status information between a signal processor (20) and either an audio source (12) or an audio sink (24). During transmission of digital audio data from audio source (12) and signal processor (20), a comparator (49) compares a cyclic redundancy check (CRCC) byte of a block of channel status information to a theoretical CRCC byte generated by a CRC generator (48). By comparing actual and theoretical CRCC bytes, comparator (49) indicates in a single bit whether audio data was transmitted correctly. Remaining bits of the CRCC byte are then used to transfer status information corresponding to transceiver (16). Similarly, during transmission of digital data from signal processor (20) to audio sink (24), a parity bit of a subframe of the digital data is used to transfer programming information from signal processor (20) to audio sink (24).

Abstract: When a tape cassette having a special tape, such as a lettering tape, is mounted into a tape printing device, which normally permits user set margins, for printing image data on a tape by driving a thermal head and a tape feed motor until all image data is printed out, the user set margin is disregarded and the tape is automatically fed for predetermined amount for setting a predetermined rear margin behind the print end portion. The tape is then automatically fed further for the same amount prior cutting the tape, at the rear end of the margin by driving a tape cutter mechanism. Thus, a rear margin is provided for the cut tape and a front margin established before the next print start portion. The amount the tape is fed is an amount that is long enough to hold the lettering tape when an image printed on the tape is transferred onto the image receiving medium.

Abstract: An amplifier having an automatic threshold control circuit (ATC, 10) and a limiting amplifier (40). The ATC (10) detects and holds a top value (peak value) and bottom value of an input signal, and outputs the middle value between the top and bottom values as a reference voltage. The limiting amplifier (40) amplifies the input signal in a linear operating region whose center is set at the reference voltage, thereby maintaining the output amplitude at a constant value. Even if the amplitude and the level of the input signals instantaneously changes by a large amount, the ATC can follow the change, so that the offset compensation and gain compensation of the amplifier can be achieved instantaneously. This makes it possible to continue producing the output of a constant amplitude with little phase deviations.

Abstract: An ink jet (10) apparatus and method provides high-resolution gray scale printing by providing multiple PZT drive waveforms (100, 110, 120), each having a spectral energy distribution that excites a different modal resonance of ink in an ink jet print head orifice (14). By selecting the particular drive waveform that concentrates spectral energy at frequencies associated with a desired oscillation mode and that suppresses energy at the other oscillation modes, an ink drop (170, 180, 190) is ejected that has a diameter proportional to a center excursion size of the selected meniscus surface oscillation mode. The center excursion size of high order oscillation modes is substantially smaller than the orifice diameter, thereby causing ejection of ink drops smaller than the orifice diameter. Conventional orifice manufacturing techniques may be used because a specific orifice diameter is not required. Jetting reliability and contaminant susceptibility are, thereby, improved by eliminating the need for an unconventionally small orifice. Changing a selected PZT drive waveform amplitude changes drop ejection velocity without changing drop volume. This invention, therefore, provides for selection of ejected ink drop volumes having substantially the same ejection velocity over a wide range of ejection repetition rates.
