Filed: 1983-03-14
Abstract: PURPOSE:To use a line in common for data communication and calling by discriminating automatically a signal transmitting a data communication request at incoming call depending whether a modulation and demodulation section detects the signal. CONSTITUTION:A modulating and demodulating device 12 incorporating a network controller is connected to the line 2 via a switching device 13. After the modulating and demodulating device 2 closes the line to the incoming call from the caller side, a calling code from the caller side is led to a calling code detecting section 29 via a switching section 27 from a demodulating section 24.

Filed: 1979-04-11
Abstract: PURPOSE:To take out an ohmic contact without a breaking of wire from a surface of chip by selectively forming a diffusion preventive film on the substrate contact taking out section and by removing the above film after a source drain layer is formed. CONSTITUTION:A field oxide film 2, a gate oxide film 3, a polycrystalline Si gate electrode 4, a source and drain forming windows 11 and 12, and a substrate contact taking out window 13 are formed on a p-type Si substrate 1. Then a resist layer 14 is selectively formed to the window 13 only in order to obstruct an ion injection, a p-ion is injected and an n-type source and drain layers 5 and 6 are formed. Next, a thin thermal oxide film 15 is formed on the whole surface except the layer 14 and a PSG 8 is laminated. Then an window is selectively opened and an Al wiring 10 is made. By performing this method, an n-layer does not appear on the p-type substrate located below the substrate contact taking out window 13. Therefore, the performance of the polycrystalline Si etching similar to the conventional one is necessary immediately after the window has been opened. Hence a difference in grade is not formed at the window-opened section and a breaking of wire does not occur on the Al wiring, thereby allowing to obtain an excellent ohmic contact.

Filed: 1978-04-17
Abstract: PURPOSE: To obtain the stable measurement results by determining the surface roughness with the use of a calibration curve from the optical intensity at the origin of a spacial frequency axis on the Fourier transforming plane of a scattered light.  
     CONSTITUTION: The beam from a laser light source 1 is changed into a parallel beam by a lens 3 to enter a transparent replica 4, which is taken out of a sample surface, so that it is scattered by the irregular surface roughness thereof. After that, the scattered beam is focused on a Fourier transforming plane a by a Fourier transforming lens 5. since there is arranged at the origin of the spacial frequency axis of the plane a a phototransistor 6 which has a minute light receiving surface, the  scattered beam of the replica 4 illuminates this so that it has an output corresponding to the illumination. As a result, if the relationship between the output of the  transistor 6 and the surface roughness is calibrated in advance with the use of a  sample having a known surface roughness, the stable measurement results of the  surface roughness can be determined from the output of the transistor 6. Incidentally, the transparent replica can be replaced by a split which has an inclination of  about 45 degrees with respect to the parallel beam from the reflective rough sample.
