Filed: 1986-05-16
Abstract: PURPOSE:To reduce the occupying time of a network in the high speed transmission of picture by using the transmission of data and picture in common and sending a picture signal with a quickened clock rate so as to attain compatibility. CONSTITUTION:A signal generated from a data terminal equipment 8 is processed into a signal proper to the transmission by a data processing circuit 5 and fed to a transmission signal processing circuit 2 via a changeover circuit 4. A data signal from the changeover circuit 4 is given to the circuit 2 at the generation of data signal when no output is given from a picture processing circuit 13. In case of a picture signal, an identification signal generated by an identification signal generating circuit 3 is inserted to a transmission signal and then sent. An identification circuit 11 discriminates whether or not the identification signal for the picture signal exists in the sent signal, and when no identification signal exists, an output of the circuit 12 is given to a data processing circuit 6. Thus, the high speed sending of the picture is attained even by one transmission while keeping the compatibility with the system and equipment of a conventional data system.

Filed: 1979-09-06
Abstract: PURPOSE:To obtain an output of stable light frequency and high power, by making the direction of polarization of a laser oscillator different from that of an injection synchronization type light amplifier to which the output of the oscillator is applied. CONSTITUTION:A compact laser oscillator 1 of low output is provided. Its oscillation output is amplified by an injection syncrhonization type light amplifier U.

Title: Thin-film treating apparatus
Inventor: NAKAMURA MORITAKA
IPC: H01L21/3065
Filed: 1982-06-29
Abstract: PURPOSE:To permit an etching gas to easily cause discharge even in a vacuum vessel maintained under a high vacuum thereby to make it possible to accurately pattern a thin film, such as an Al wiring film, by expanding a part of a discharge gas introducing tube to form a gas introducing chamber, and contracting the lower part of the tube to form a thin tube. CONSTITUTION:A discharge gas introducing tube 11 is locally expanded at a part thereof which is to be exposed to an electric field to form a gas introducing chamber 12 of quartz. The lower part of the tube 11 is contracted to form a thin tube 13. When a voltage is applied between a substrate support 15 and an electrode 18, an CCl4 gas being introduced from the gas introducing tube 11 easily causes discharge, since the pressure at the thin tube 13 is higher than that inside a treating vessel 14. With this discharge serving as if it were a pilot flame, discharges are easily caused successively even in the treating vessel maintained under a comparatively low pressure. Since it is possible to treat a thin film while maintaining the inside of the treating vessel under a comparatively low pressure, the thin film can be accurately etched in a desired pattern.

IPC: H01L21/322
Filed: 1989-05-08
Abstract: PURPOSE: To eliminate getter substance, to avoid corrosion of a semiconductor surface and to prolong the life of a carrier irrespective of diffusion depth by dropping a diffusion temperature to a desired one and generating a getter operation in a second process. CONSTITUTION: Boron is adhered to one of the double main faces of a silicon monocrystal disk-like semiconductor substrate 10 as doping substance and phosphorus is adhered to the other face as doping substance. In a first process, boron and phosphorus are diffused into the substrate 10 until they reach prescribed depth with a prescribed condition. In the condition, the diffusion temperature is 1265±C and diffusion time in an oxide atmosphere is thirty hours. In the following second process, diffusion is executed with the diffusion temperature of a value between 1050'C and 1150 deg.C, by which diffusion depth is not affected at all or not affected so much, namely, 1100 deg.C here for thirty hours. Thus, the getter operation for prolonging the life of the carrier is generated and the forward voltage of the diode is dropped in the substrate 10 in the process. Consequently, the life of the carrier can considerably be prolonged irrespective of the diffusion depth.
