Abstract: A key telephone terminal (T1) connected via a four-wire line (useful connection a, b and control connection c, d) to the exchange (VE) is also connected to a subscriber line (ATn), in addition to a data terminal (fax, PC). Since when a request for a connection comes from such a device, an indication occurs both on the useful connection and on the control connection but when a data terminal is connected, an indication only occurs on the useful connection (a, b wire), the system can tell whether a data communication or a normal communication exists. If a data communication is recognised, a temporary data protection is put into effect during the period of time of data transmission. Thus, the relevant subscriber connection is blocked for particular service features which can be activated by the system or by another subscriber (for example call insertion, call waiting and intrusion). Follow-up functions of manipulations at the key telephone terminal which are transmitted via the control connection are also suppressed during the existence of the temporary data protection. <IMAGE>

Abstract: An optical switching system comprises an input terminal for receiving an optical wavelength-division multiplexed (WDM) signal in which optical signals differing in center wavelength  i  (i = 1 to N) are wavelength-division multiplexed, the optical signal being an optical frequency-­shift keying (FSK) signal which is a first optical FSK signal F i . A splitter splits the optical WDM signal correspondingly to the wavelengths λ i  to generate optical wavelength-corresponding WDM signals W i . Wavelength extracting circuits extract optical FSK signals F j  (j = 1 to N) pertaining to wavelengths λ j , to which the wavelengths λ i  are to be switched, from the optical wavelength-corresponding WDM signals W i  to generate optical amplitude-shift keying (ASK) signals A j  pertaining to the wavelengths λ j  to be switched to. Wavelength switches switch the optical ASK signals A j  to second optical FSK signals F i  corresponding to the wavelengths λ i . A wavelength multiplexer wavelength-­multiplexes the second optical FSK signals F i  into an optical switched WDM signal. This optical WD switching system reduces the signal deterioration due to crosstalk by optical signals of wavelengths other than that to be selected when an optical signal of a certain wavelength are being selected by a tunable or a fixed wavelength filter.

Abstract: The invention relates to a method for bending tubes made of a certain material and having a certain cross-sectional shape through a desired angle  alpha i and with a certain bending radius (referred to below as bending objective), in which first of all a check is made as to whether an appropriate bending angle  gamma i and a characteristic quantity, which is a measure of the springback of the tube in the case of the bending objective concerned, are already known for the bending objective. If the appropriate bending angle and the characteristic quantity are unknown, the tube is bent through an angle  alpha i; the characteristic quantity which is a measure of the springback of the tube in the case of the bending objective concerned, and any bending angle  gamma i, which is chosen so that, after the bending of the tube through  gamma i =  alpha i +  epsilon i taking into account the springback, a bend through the desired angle  alpha i remains, are determined and stored. The tube is bent further to the bending angle  gamma i. If the same bending objective has already been accomplished, then, in the case of further identical bending objectives, the tube is bent through the bending angle  gamma i. When these further identical bending objectives have been accomplished, the characteristic quantity is determined and compared to the already known characteristic quantity and, where required, a new appropriate bending angle is determined.

Abstract: A frequency of a chrominance signal including a jitter component and separated from a color video signal is converted from a first frequency to a second frequency by first frequency converting means (51). Then, the chrominance signal which frequency is converted to the second frequency is converted to have the original frequency by second frequency converting means (52). The first frequency converting means and the second frequency converting means both includes a multiplier (51a,52a) and a bandpass filter (51b,52b). One multiplier of the first or the second frequency converting means receives a frequency signal corresponding to a phase difference between a reference frequency signal and a color burst signal separated from the chrominance signal. As a result, the jitter component is removed from the chrominance signal either in the first or the second frequency converting means. In the first and the second frequency converting means the input signal and the output signal so widely differ from each other in frequency that the respective frequency components included in the output signal of the multipliers in the respective frequency converting means expend widely along an axis of a frequency. As a result, the bandpass filter in each frequency converting means is enabled to easily extract only a signal of a desired frequency component.

Abstract: An air conditioning system comprises an inverter that inverts commercial power into a variable-frequency AC and supplies it to a compressor; a DC power circuit for converting the commercial power into DC current; a unit for detecting an analog value of current supplied from the commercial power; and a control unit to control inverted digital data by compensating the digital current data discrepancy due to scattering of the DC control voltage, when there is A/D conversion after an actual power supplied to the inverter has been detected via the detector. The control unit comprises an A/D converter that uses the output of the DC current circuit as the reference for converting the current detection unit output into digital DC data, a controller that compares the allowable current data stored beforehand with the current data converted by the A/D converter and limits the output frequency of current inverted by the inverter so that commercial power current does not exceed the allowable value, a memory to store a compensated current value so that discrepancies in the current data can be compensated for on the basis of DC output discrepancies, and a compensator to compensate the current allowable value data.
