Patent EP-0263949-A3 (EP)
IPC: B41J2/27
Filed: 1987-08-28
Abstract: The trajectory of an electromagnetic actuator is adjusted by pulse-width-modulating feed-­
back control of the waveform which energizes the coil. As applied to actuators for impact 
printing, the objectives of the control scheme are to regulate the armature's time of flight and 
its velocity at impact, in spite of disturbances, thereby to provide higher-quality printing at 
increased speed. Each actuation is produced by energizing the coil with a series of pulses. 
Regulation is accomplished under microprocessor control by measuring the state variables 
of the system -- armature position, armature velocity, and coil current -- at the beginning of 
each pulse, comparing these measurements to ideal values, and modulating the width of the 
pulse as a function of the errors. In general, the appropriate functional relationship between 
the measure errors and the pulse-width modulation is nonlinear, and is different for each 
pulse in the series. Systematic means for determining these relationships are given.

Title: Active impedance line feed circuit
IPC: H04M19/00
Filed: 1987-11-20
Abstract: A typical active impedance line feed circuit includes tip and ring amplifiers (20, 40) being controlled in response to signals at tip and ring voltage taps (6, 7) by a control circuit (60) to exhibit a.c. impedance and d.c. resistance characteristics for the purpose of supplying energizing current via tip and ring terminals (2, 3) for tip and ring leads of two wire communication line. In one example of the active impedance line feed circuit, improved operational tolerance of longitudinal interference and of a ground fault condition is provided by a d.c. amplifier (210a) being responsive to voltages at the tip and ring terminals. The circuit is characterized in that an inverting input of the d.c. amplifier is connected via resistors (212a, 313a) to the tip and ring voltage taps. In operation, the d.c. amplifier provides complete cancellation of all common mode signals at the tip and ring voltage taps. A compensation amplifier (235) is also connected between the tip and ring voltage taps and is responsive to the output of a control amplifier (231) for compensating for non-symmetrical current, the non-symmetrical current being introduced between the tip and the ring voltage taps by normal operation of the control circuit. Thereby, a threshold of ground fault current limiting action is substantially constant under all operating conditions. The d.c. amplifier is conveniently manufacturable in integrated circuit technology along with the remaining amplifiers in the active impedance line feed circuit.

Title: Iron oxide for ferrite
IPC: C01G49/06
Filed: 1988-12-15
Abstract: According to the invention, an iron oxide is provided for ferrite having a Mn content of 0,1 to 0,3 % by weight and a P content of not more than 0,005 % by weight. Such an iron oxide can easily be produced by making an iron chloride solution, dephosphorizing the iron chloride solution by a simple process and oxidizing roasting the dephosphorized solution to provide the desired iron oxide. Although Mn is contained as an impurity the ferrite properties are not impaired thereby since attention is paid to the impurities of P which are at a low level. Accordingly, soft ferrite can be produced having excellent ferrite properties.

Abstract: In a vehicle window glass antenna, linear electrodes (10a,10b) are 
bonded to upper and lower edges of a transparent conductive film (2) 
desposited on substantially the entire surface of a glass window 
(1). Tuning conductors are formed by strip-shaped transparent 
conductive films (2a,2c) separated by cut lines (3a,3b) from a 
central portion (2b) of the film (2) which is connected by feeder 
electrodes (4a,4b) to a source (8) of heating current. The tuning 
conductors (2a,2c) are arranged to tune antenna elements including 
the linear electrodes to a specific reception band, thereby 
increasing a reception gain without degrading the radiant heat 
reflecting performance of the transparent conductive film (2). A 
diversity receiver (14) selects the better signal from the output of 
the two antenna elements (2a,10a; 2c,10b).

IPC: H04B3/23
Filed: 1989-12-07
Abstract: A procedure is described for cancellation of the echo produced in telephone connections with electrical time-variant characteristics such as for example those affected by phase roll. The echo canceller obtained in accordance with the procedure which is the object of this invention produces an estimate of the echo signal by means of appropriate digital filtering of the signal originated by the far-end talker. The estimated echo is then subtracted from the actual echo. Filtering is activated by an IIR digital filter (FTR) whose adaptive coefficients are updated by use of an adaptive algorithm based on decimation of the square error. The high convergence speed of said algorithm in the calculation of the coefficient correction step allows a correct estimate of the echo even in case of connections affected by phase roll.
