IPC: H04J3/06
Filed: 1987-02-13
Abstract: PURPOSE:To prevent a signal spectrum of each transmission line from being remarkably distorted or an fault from being induced in succeeding lines by detecting a device fault of a transmission line sent from a host terminal station through out of synchronism of a frame synchronizing circuit and inhibiting a descrambled signal. CONSTITUTION:If a device fault takes place in a transmission line connected to the host terminal station, the fault of the transmission line from the host terminal station is detected by using an out of synchronism signal (h). If a demodulated signal (f) becomes a signal string having remarkably biased mark rate because of the device fault of the host terminal station through the transmission line, the out of synchronism signal (h) goes to logical value '0', and since an AND gate 14 inhibits a descrambled signal (k), the signal 1 outputted from the AND gate 14 and the output signal (m) being the signal of destuffed signal 1 become a signal string of a prescribed logical value '0'. As a result, the output signal (m) is not a signal string remarkably similar to the scramble pattern (b).

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent static electric power based upon a bias voltage operating on a cantilever from exerting influence on a working force image by applying the bias voltage to obtain a current image and not applying the bias voltage to obtain the working force image. SOLUTION: The figure shows a scanning signal and a bias voltage at the time of a raster scan and is part of a control signal at the time of the scan, showing the state of (y)-directional three-time stepwise movement. In the direction wherein an (x) scanning signal increases, i.e., on the going way of the (x) scan, the bias voltage is set to 0 to detect an output signal and in the direction wherein the (x) scanning signal decreased i.e., on the return path of the (x) scanning, the bias voltage is set to Vb to detect the current signal. Consequently, even when a soft cantilever is used, as accurate working force image and a current image are obtained by a scanning type force microscope(SFM)/ scanning type tunneling microscope(STM) hybrid machine.
